The water level of River Godavari has crossed the 52-feet mark, just one feet below the third warning (danger) level of 53 feet, at the temple town of Bhadrachalam on Friday afternoon, prompting the authorities to evacuate people living in the flood prone areas to safer places in the Bhadrachalam Agency.
Earlier, the authorities issued the second warning at 7.15 a.m. on Friday morning after the river surpassed the 48-feet mark. The swollen river is likely to touch the danger level of 53 feet on Friday afternoon.
Flood threat looms large over 111 villages in low-lying areas in Venkatapuram, Charla, Wajedu, Kunavaram, V R Puram, Dummugudem, Chintur and Bhadrachalam mandals as water level neared the third warning level.
A high alert has been sounded in the flood-prone areas along the river course in the Bhadrachalam Agency as the river turned perilous owing to the unabated rains in the catchment areas. All the tributaries of the Godavari including Taliperu are in spate.
Road communication to more than 60 villages in Wajedu, Charla, Velerupadu, Kunavaram, Aswapuram, Dummugudem, Venkatapuram and some other mandals was snapped as swollen streams swamped the low-level culverts and causeways at various points on Charla-Venkatapuram main road and other routes in the Agency areas.
Backwaters from the swollen river touched some low-lying areas in Bhadrachalam town and floodwaters entered houses at various flood-prone villages in Charla, Aswapuram and Venkatapuram mandals. The officials shifted people living in the flood-prone areas to temporary shelters set up in ashram schools and other government buildings. Wajedu mandal in Bhadrachalam division received the highest rainfall of 460.4 mm, followed by Venkatapuram, which recorded 210.2 mm of rainfall in the last 24 hours, till 8 a.m. on Friday.
The flood situation turned grim ahead of the gram panchayat elections in the Bhadrachalam division slated for July 23. A flood control room (08742-231600) has been set up at the Collectorate in Khammam. Another control room (08743-232444) has been functioning at the Sub-Collector’s office in Bhadrachalam.

PM's address at the ASSOCHAM Annual General Meeting

“I am delighted to be with you today to inaugurate the ASSOCHAM’s AGM, 2013. ASSOCHAM has, over the years, provided valuable inputs from time to time for shaping our policies for economic and industrial growth. I would like to compliment Shri Rajkumar Dhoot and all his colleagues for their work and I am happy to share my thoughts with you today.
Let me begin by stating upfront that we, like most other countries, are going through a difficult period. I know that business is deeply concerned about the slowdown in our economy. It is looking to the government to bring the economy back to a higher growth path. This, I believe, is a legitimate expectation and is also upper most in our mind.
When things are going well, government should interfere as little as possible. When things are going bad, as they seem to be at present, it is the responsibility of the Government to become more pro-active.
The most immediate cause of worry is the recent volatility in foreign exchange markets. Much of this was due to global markets reacting to the likelihood of a withdrawal of Quantitative Easing III by the US Federal Reserve Bank. Large volumes of funds were withdrawn from emerging markets and there was a depreciation in many emerging market countries including Turkey, Brazil and South Africa.
We too experienced a significant depreciation in the exchange value of the rupee. In our case, it was perhaps exacerbated by the fact that our current account deficit in the balance of payment had increased to 4.7 percent of GDP in 2012-13.
I can assure you, we are committed to bringing the current account deficit under control by addressing both the demand side and the supply side of the problem. On the demand side, we need to reduce the demand for gold and the demand for petroleum products – the two biggest components of our trade deficit.
We have taken measures to control the demand for gold and I am happy to say they have had some affect. Gold imports declined sharply in June, and I hope they will stay at normal levels from now on.
On petroleum products, we began a process of correcting the prices of petroleum products last year. The gradual correction that was taking place in diesel prices had reduced the gap in under-recoveries from almost Rs 13 per litre to less than Rs 2 per litre. Unfortunately, some of this has been undone by the depreciation of the Rupee. However, our policy of adjusting prices to progressively eliminate under-recoveries remains in place.
On the supply side, we need to push our exports. The depreciation in the rupee will help. Of course, there is a time lag before this benefit will be felt in terms of export volumes, but orders being booked from now on would certainly benefit. We are also trying to remove the constraints in the export of iron and other ores which saw a considerable decline during the last one year.
The Reserve Bank has done its bit to stabilise market expectations. Initially it injected dollars into the market. This helped to some extent. More recently, it took additional steps to raise short term interest rates. These steps are not meant to signal an increase in the long term interest rates. They are designed to contain speculative pressure on the currency. Once these short term pressures have been contained, as I expect they will be, the Reserve Bank can even consider reversing these pressures.
Looking ahead, the rupee depreciation will help Indian industry to compete effectively with other countries, both in export markets and against their imports in our markets.
I hope industry is thinking seriously of how to become more competitive. It is because we are confident that it can that we have entered into Comprehensive Economic Partnership Agreement with the ASEAN countries as well as the Republic of Korea. We are hoping to conclude a similar agreement with the European Union soon.
Ideally we should bring the current account deficit down to 2.5 percent of our GDP. It is clearly not possible to do this in one year, but I expect that the current account deficit in 2013-14 will be much lower than the 4.7 percent level recorded last year. It will decline further next year. We will use all policy instruments available – fiscal, monetary and supply side interventions to ensure that the Current Account Deficit declines further over time.
Looking at the medium term prospects, I feel we can and we should remain optimistic. The basic fundamentals of our economy are sound and healthy. We have been taking all possible measures to correct imbalances on the macro front.
The fiscal deficit, which is the accumulated effect of the fiscal stimulus given in the past, had expanded and it needs to be reduced. The Finance Minister has targeted fiscal deficit of 4.8 percent of GDP in the year 2013-14 and announced continuing reductions of about half a percentage each year subsequently, up to 2016-17. We are determined to meet the target for this year.
We also need to take steps that will revive the momentum of investment. A major focus of concern in the past few months is that many projects have been held up for various reasons. We have seen a very strong expansion in power generation capacity but coal supply became a problem. We have now resolved this problem and the fuel supply agreements are being signed which will ensure that all plants that are commissioned by 2015 will have adequate supplies of coal consisting of a mix of domestic and imported coal.
Many projects have been held up for lack of regulatory approvals. These are being expedited. A separate cell has been set up in the Cabinet Secretariat recently to identify big ticket projects, both in the public and private sectors, and to see how they can be helped through various hurdles.
Infrastructure is absolutely critical for our medium term growth prospects and we are monitoring progress in this area on a quarterly basis. Several initiatives are being pursued.
• The Government has plans for setting up two major ports in Andhra Pradesh and in West Bengal.
• New airports are envisaged to come up in Navi Mumbai, Juhu, Goa, Pune and Kannur.
• At 50 other locations, new small airports are being built.
• Major railway projects, including an elevated rail corridor for Mumbai, are being processed.
• The feasibility of a bullet train from Mumbai to Ahmedabad is being studied.
• Industrial Corridors from Delhi to Mumbai, Amritsar to Kolkata and Chennai to Bangalore are being considered.
All these initiatives are being monitored at the highest level with a sense of urgency.
There are several other reforms that have been undertaken over the last one year.
• The Banking Laws have been amended to raise the cap on voting.
• Subsidy reform and rationalisation has started in full force. Direct Benefit Transfer Scheme is being rolled out across the country to reduce both wastage and corruption in delivery of public service.
• Foreign Direct Investment has been liberalised in single brand retail, multi-brand retail, civil aviation and power exchanges. More FDI reforms are on the anvil as has been reported.
• A new bank licensing policy has been announced and new licences are soon to be awarded.
• GAAR, which has been a subject matter of considerable concern to industry, has been postponed by 2 years and there is greater clarity on the rules.
• Taxation issues of the IT sector and of development centres have been resolved based on the Rangachary Committee report.
• Public Sector investment has been fast-tracked and I have estimated that over Rs 120,000 crores has been invested by major Public Sector Units last year.
• Infrastructure Debt Funds have been rolled out.
• Sugar has been fully decontrolled.
• Railways have corrected their fares for the first time in a decade.
• Construction has begun on the Dedicated Freight Corridor.
• The investment policy for urea has been approved.
• Gas pricing has been corrected to reflect market realities better.
• Procedural improvements have been made in the road sector to improve the economic viability of projects.
I could go on, but my purpose was only to show that we have acted on several fronts. We will persevere with these initiatives and I hope that their impact will be felt in the second half of this year.
I would not like to make a forecast of what our growth will be in the year 2013-14. The IMF has recently reduced its earlier projection of growth rates for all countries including India, for 2013. We had targeted 6.5 percent growth at the time the Budget was presented. But it looks as if it will be lower than that.
Industrial growth has not yet recovered. However, I am happy to say that agriculture looks well set to show a good performance. In fact, one of the important achievements of our Government is that agricultural performance has improved considerably. In the Tenth Plan period agriculture grew at 2.4 percent. In the Eleventh Plan period it grew at the rate 3.6 percent. In the Twelfth Plan we have targeted 4 percent growth for our agricultural sector. I am hopeful that the current year, with the rains being plentiful thus far, agriculture will do well. This will help revive demand in rural areas which will contribute to stronger industrial performance in due course.
I must emphasise that it is not the exact growth number for 2013-14 that matters. What is important is that the economy should turn around from 5 percent achieved last year. There is a very good chance that we can achieve that with good agricultural performance and the effect of the various actions we are taking on infrastructure.
Thereafter we will try to accelerate to higher grounds in 2014-15.
Before concluding, let me address the issue of UPA Government’s performance. Our political critics focus on the experience of one bad year. This makes for good television but it is a very distorted picture. I invite you to consider the following.
• The average growth rate in the 8 years of the UPA from 2004-05 to 2012-13 was 8.2 percent per annum. This is much better than the 5.7 percent reached in the previous 8 years.
• I have already mentioned that agriculture did much better in the Eleventh Plan than in the Tenth Plan. This is reflected in real per capita rural consumption rising at 2.9 percent per year between 2004-05 and 2011-12 compared with only one percent between 1993-94 and 2004-05.
• Rural real wages have also risen much faster (6.8 percent per year in the 11th Plan as compared to an average of 1.1 percent per year in the ten years preceding it).
• The percentage of population below the poverty line declined at 0.75 percentage points per year before our government came to office in 2004-05. It has fallen more than 2 percentage points per year between 2004-05 and 2011-12.
I think this is a record that any government can be proud of. I agree we have had one bad year. I assure you we will get out of it.
I have touched upon some of the issues that I know concern the captains of industry and have talked about the areas where action needs to be taken. I assure you we will leave no stone unturned to ensure that our economy rebounds. I appeal to each one of you not to be overcome by negative sentiments. We should stay the course, and work together to achieve our collective national goals.
With these words, I wish this conference and the ASSOCHAM all success.”
Thank You.
 

Environmental degradation costing India 5.7% of its GDP: World Bank

MUMBAI: At a time when many of India's infrastructural projects are caught in the throes of an environment versus development conundrum, a new report released by the World Bank estimates that environmental degradation is costing India around 5.7% of its GDP every year.
The report, "Diagnostic Assessment of Select Environmental Challenges in India" is the bank's first national economic assessment of environment-related degradation in India. It analysed the losses of environmental health and natural resources, and provided a valuation of biodiversity and ecosystem services in India, among other valuations.
"The annual cost of environmental degradation in India amounts to about Rs 3.75 trillion ($80 billion) equivalent to 5.7% of GDP," stated the report. Among the highest to blame was pollution, mainly outdoor pollution arising from particulate matter (PM10) that was largely due to the burning of fossil fuels along with the losses due to the lack of access to clean water supply, sanitation and hygiene, stated the report.
"The costs for outdoor/indoor air pollution are primarily driven by an elevated exposure of the young and productive urban population to particulate matter pollution. This results in a substantial cardiopulmonary and Chronic Obstructive Pulmonary Disease mortality load among adults," stated the authors of the report in a press note.
The report was meant to underline the need for India to green its growth. The issue of lowering emission has been a contentious one between developed and developing nations, with the latter including India stating that they should be allowed to grow on par with countries which have had an early advantage before they impose emission cuts.

Bihar school meal poisoning incident

Location of Bihar in India
Location     Mashrakh, Bihar, India
Date     July 16, 2013
Deaths     23–27
Injured (non-fatal)     ~25

On 16 July 2013, at least 23 students died and dozens more fell ill after eating a contaminated free meal at a primary school, in Dharmashati Gandaman village, Mashrakh block, Saran district, Bihar, India.[1][2] Angered by the deaths and illnesses, villagers took to the streets in many parts of the district in violent protest.[3]

Background

Across India, the Midday Meal Scheme provides roughly 120 million children with free lunches, making it the world's largest school lunch program.[4] Inspite of corruption involved in implementing the scheme, it aims to fight widespread poverty, improve children's school attendance and health, as large number of India's children suffer from malnutrition.[5][6]

Bihar in northern India is among the nation's poorest states.[7] According to Mashrakh residents, students have suffered from food poisoning after eating school lunches on multiple occasions.[8] Bihar's education minister, P. K. Shahi, said complaints about food quality were not uncommon, but that there were no reported incidents of widespread food poisoning during his tenure.[5] The nonprofit Iskcon Food Relief Foundation says the meal programs in Bihar and neighbouring Uttar Pradesh are the worst in India. Public health is poor in general, with most water sources contaminated, and hospitals are underfunded.[3]

The primary school in the village of Dharmashati Gandaman was established in 2010 and enrollment in 2013 was 89 children.[9] Since the school did not have permanent infrastructure, the food materials for midday meals were stored at the house of the headmistress, Meena Devi.[10]
Incident

On 16 July 2013, children aged between four and twelve years at the Dharmashati Gandaman primary school complained that their lunch, served as a part of the Midday Meal Scheme, tasted odd.[3] Children who questioned the food were rebuked by the headmistress.[5] Earlier, the cook had told the headmistress the school's new cooking oil was discoloured and smelled odd.[8] She replied that the oil was purchased at a local grocery store and safe to use.[8][7] The cook, who was hospitalized with food poisoning, later told the press it looked like there was "an accumulation of residual waste at the bottom [of the oil jar]".[7] The meal consisted of soya beans, rice, potato curry, that were cooked at the school.[7]

About 30 minutes later, the children began to have stomach pains and shortly thereafter began to have vomiting and diarrhoea. The number of ill children overwhelmed the school and local medical system. Some sick children were simply sent home, forcing their parents to seek help on their own.[3] According to the official count, 23 children died as a result of the contaminated food.[1] Parents and local villagers, however, said at least 27 had died.[2] Sixteen children died onsite, while four others were declared dead upon arrival at the local hospital. Others died at the hospital. Among the dead were two children of a female cook, Panna Devi; her third child survived.[10][11] A total of 48 students fell ill from the contaminated food. Three remained in critical condition as of 17 July.[7] Thirty-one children were moved from the local hospital to Patna Medical College Hospital (PMCH) for further treatment.[5]
Cause

Initial indications are that the food was contaminated by organophosphorus compounds, a class of chemicals commonly found in insecticides.[5] A local government administrator commented "It appears to be a case of poisoning but we will have to wait for forensic reports.  Had it been a case of natural food poisoning, so many children would not have died".[7] Late on 17 July, officials stated that they believed the cooking oil had been placed in a container formerly used to store insecticides.[3] According to state officials, the cooking oil used in the food had been purchased by the school's headmistress from a grocery store owned by her husband.[1]
Reaction

Nineteen of the children's bodies were buried on or near school grounds in protest. Across Bihar, numerous students refused to eat their meals in the days after the poisoning incident.[1]

On 17 July, hundreds of Mashrakh residents took to the streets in protest.[8] Demonstrators lit fires and burned effigies of Bihar Chief Minister Nitish Kumar.[7] Four police vehicles were damaged by the fires.[8] Others threw stones at the police station and chanted slogans denouncing the government.[7] Some villagers demanded that the Midday Meal program be abolished.[2] Roads and rail lines were blocked by angry protestors carrying sticks and poles.[8] Desks and chairs from the school were taken and smashed, while the kitchen area was destroyed.[1][2] In nearby Chhapra, multiple arsons were reported, including reports that a crowd set fire to a bus.[8][2] No injuries were reported in either city.[3]

Shahi commented that many people involved in the program are looking for easy money and that "it is just not possible to taste meals in all the 73,000 schools before children eat the food."[3] He alleged that the poisoning was the work of political conspirators aiming to destabilize the government.[10] He also alleged that the contaminated oil had been purchased from a member of a rival political party.[2] Opposition party members accused the ruling Janata Dal party of acting too slowly.[7] Some politicians called for a general strike.[5]

The Bihar government promised a thorough investigation and offered INR200,000 (US$3,400) compensation for families of the dead children. Kumar called an emergency meeting and dispatched forensic experts to Mashrakh.[8] Headmistress Devi and her husband fled after the deaths became public knowledge and she was suspended by administrative authority.[7][8] A First Information Report has been filed against Devi and police are searching for her.[10]

Uttar Pradesh Plan for 2013-14 Finalized

The Annual Plan for 2013-14 for the State of Uttar Pradeshwas finalised today at a meeting between ShriMontek Singh Ahluwalia, Deputy Chairman, Planning Commission and Mr.AkhileshYadav, Chief Minister of Uttar Pradesh. The Plan size has been agreed at Rs.69,200crore which includes the central assistance to the State Plan of about Rs.11,225crore. In addition, an amount of about Rs.18,000crore is likely to flow from the Centre to Uttar Pradesh through various Centrally Sponsored Schemes. Thus, Plan funding from the Central Government to the State of Uttar Pradesh, from all sources, is expected to be over Rs.30,000crore during 2013-14.

In his comments Mr Ahluwalia appreciated the plan performance of the State and said that State was moving in the right direction and social indicators were positive. He said UP’s performance is very important as it will have major impact on the outcome in the 12th Plan. On the plan performance of the State, he complemented the State Government for restoring economic activity and focusing on the development of social and physical infrastructure. He said the State needs to further encourage private participation by creating an atmosphere conducive to investment. Education& Health should be given priority while working out development strategy.

The State Government was appreciated for the reforms being taken up and it was pointed out that the State like Utter Pradesh can take lead in this direction and encourages others to follow. The State was advised to available benefit available under the innovation initiative of the central Government. While appreciating initiatives taken in water management, the State Government was advised to resort to optimum utilization of limited water resources while planning for five per cent growth in agriculture.

The heavy dependence on ground water for irrigation by the State is a major cause of concern the State should initiate a comprehensive study for mapping the aquifer so that use of ground water can be optimized. The funds from MGNREGA may be dovetailed to take up work in water conservation/harvesting activities. The Command Area Development activities should be implemented pari-passu with the project implementation so that the last mile connectivity to the Major & Medium Irrigation projects can be ensured.

Attention was drawn to the share of manufacturing sector/industry in GSDP and it was pointed out that it was declining in the State due to unfavourable macro-economic conditions. The proposed new industrial policy aimed at creating investor friendly environment was step in the right direction. Private investment has to be incentivised to revive the industrial sector in the State. The efforts of the State Government to develop NOIDA and greater NOIDA as a centre of excellence are appreciable. Regarding the State Government’s proposal to connect all district headquarters by four-lane roads and construct 300 bridges and 100 ROB in the State, it is suggested that State may use PPP mode for these projects so that they could avail of benefits under Viability Gap Funding Scheme.

Briefing the Commission on the development strategy, Chief Minister AkhileshYadav said that a number of new policy initiatives have been taken. State has made public its development agenda which will be strictly followed throughout the year. This includes time bound implementation of national flagship programmes and effective implementation of agriculture policy. He said infrastructure and industrial policy is being implemented to attract private investment and all district headquarters are being connected by 4 lane roads by the end of the plan while all 500 plus habitations will be connected with all-weather roads in two years.

He said the State Government would focus on development of economic infrastructure and more than 20 per cent of the outlay would be ear-marked for this sector. He said on social infrastructure the State Government was proposing to spend 32 per cent of outlay. He added that the State achieved better than national growth rate during 2012-13. Against all India average of 5.0 per cent Uttar Pradesh achievement was 5.4 per cent. Growth in agriculture was 2.6% while industry and service sectors grew by 2.8 and 7.6 per cent.

Andhra Pradesh Plan for 2013-14 Finalized
The Annual Plan for the year 2013-14 for the state of Andhra Pradesh was finalised here today at a meeting between Deputy Chairman, Planning Commission, Mr. Montek Singh Ahluwalia and Chief Minister of Andhra Pradesh, Shri N.Kiran Kumar Reddy. The plan size has been agreed at Rs.53,000crore.

Mr Ahluwalia complemented the State Government for efforts to make development truly inclusive and also for the efforts aimed at promoting public private partnership in the development of both social and physical infrastructure. He said better involvement of private sector would be needed during 12th plan period as State funds would not be enough to meet the needs of infrastructure development. He said the State Governments should come forward with the suggestions that can improve efficiency of flagship schemes and commission would consider them while finalizing plan document. Efforts are on to permit state specific flexibility in the guidelines of Centrally Sponsored Scheme for this purpose. On plan performance of the State, Mr Ahluwalia said the State has been doing fairly well on all sectors. Both financial management and social welfare are well prioritized in the planning strategy. He said the State has been truly following Planning Commission’s policy of more inclusive growth with focus on farmers and under privileged. Appreciating performance in the agriculture, he said Andhra is among the large States which have registered four per cent plus growth.

Performance in Human Development is satisfactory. There was a fall in the IMR during the Eleventh Five Year Plan but the achievement fell short of the target of 28. The total IMR of the State is 43 per thousand live births with wide disparity in IMR between rural and urban sectors. It is 47 and 31 per thousand live births in rural and urban sectors, respectively. The decline in MMR during the plan period was also less than the target of 65 during the plan period. The State may consider introduction of 4th ANC to emphasize planned delivery, strengthening of referral transport system and commencing mobile linked mother and child tracking system in all the districts.

It was pointed out that in the 11th plan outlay for Andhra Pradesh was approved at Rs. 187797 crore of which it has achieved Rs. 161756 crore, i.e. 86% of the approved outlay. The 12th Five Year Plan of the State has targeted plan outlay is Rs.342842 crore of which Rs.48935 crore was approved for 2012-13.The GSDP growth of the State is more than the national level growth rate and the sectoral growth rates also places the state above the national growth rates. In terms of mobilization of resources, Balance from Current Revenue (BCR) has remained positive at about 43% of the aggregate plan resources, with State’s Own Resources (SOR) contributing about 50% of aggregate resources during the 11th Five Year Plan. In 2012-13, BCR (Latest estimates) account for 40% of the aggregate resources and SOR is 40% of the aggregate resources. Tax-GSDP ratio for Andhra Pradesh has improved to about 8.5% of GSDP in 2012-13 as compared to 7.9% of GSDP in 2007-08. The State is revenue surplus, and fiscal deficit is within a comfortable level of 3%.

Planning Commission expressed concern over the slow progress in the literacy rate and pointed out that as per Census 2011, the State’s literacy rate is 67.6% with male literacy at 75.6% and female literacy at 59.74%. The State’s literacy rate is much lower than the national average of 74.0%.

In the agriculture sector, it was suggested that crop diversification and intensification in the rice fallows of coastal districts through oilseeds and pluses should be pushed under National Food Security Mission and RKVY. The processing facilities for fruits and vegetables may be promoted in PPP mode. The state may utilise the funds provided in the new initiatives on Public Private Partnership for Integrated Agricultural Development (PPPIAD) under RKVY.

On Communication and information technology the State was asked to formulate a suitable e-governance plan for the State may and implemented and also re-engineering of the present processes for weeding out obsolete processes and procedures must be undertaken for implementing any e-governance project on priority basis. The state government was also advised to get impact study done on Industrial Investment Promotion Policy (2010-15), under which various incentives/concessions like 15% capital subsidy, 100% VAT/CST reimbursement, 100% stamp duty remission and other subsidies are given to micro, small and medium enterprises.

Giving an account of plan performance and future strategy, Mr Reddy said that despite constraints State has been able in maintaining a satisfactory growth rate while pushing for truly inclusive growth strategy. He said human development indicators are exhibiting positive trend as State continues to focus on faster development of backward areas, education, health and infrastructure of SC/ST population.

He said the 12th Five Year Plan has recognized the importance of giving a big push to the Industry sector for accomplishing the envisaged growth, whose contribution to the State GSDP remained around 25% during the last decade. A targeted approach giving focus to MSMEs and small industries for generation employment through skill up-gradation remained core agenda for the 12th Plan. He said the State would target a growth rate of ten per cent during 12th plan. It would broad-base growth involving all sectors and all sections of people. Facilitate and enhance the ability of all sections of society to contribute to the development process and thereby benefit from growth.

He requested the Planning Commission for pushing central Government to expedite implementation/ completion of projects which have major bearing on the development of the State. He also requested that Indira Sagar Polavaram Project be given early revised investment clearance and along with Ambedkar Pranahita project be declared national projects.

Political meddling proves toxic for pollution control boards

 Boards are understaffed, have little time for meetings, inspection or regulation, says study

Environmental protection seems to be in shaky hands with political appointees nominated to head state pollution control boards (SPCB) in some places. In one case, the educational qualification of the chairperson was tenth standard.
In Karnataka, for instance, the chairperson of the SPCB is Vaman Acharya, a senior BJP leader. In Himachal Pradesh, it is Kuldip Singh Pathania, a Congress party leader and former MLA, and, in Uttar Pradesh, Waseem Ahmed Khan was the head of the board for six months till he was removed in February 2013. Khan was appointed at the behest of a political party leader.
In Arunachal Pradesh, Ramol Barang, a sitting NCP MLA heads the SPCB and in Manipur the honour has fallen on E. Dwijamani Singh, also a sitting MLA. In Maharashtra J.S. Sahani, a former bureaucrat, heads the board. Ms. C. C. Sangdarpa, a tenth standard pass, was chairperson of the SPCB in Sikkim from 2005- 2009, according to a new study based on information culled under the Right to Information (RTI) act, which has found serious lacunae in the functioning of 28 SPCBs in India, mandated to implement laws related to environmental protection and air and water quality.
The study says such appointments are in blatant violation of Supreme Court guidelines and the law, according to which chairpersons should be qualified in the field of environment or should have special knowledge of the subject. Mr. Sahani has retired and by appointing him for only one year, the Maharashtra government has violated section 4 of the Water (Prevention and Control of Pollution) Act 1974 which says the minimum tenure should be three years.
Titled “Environmental Regulatory Authorities in India: An assessment of state pollution control boards,” by Geetanjoy Sahu, assistant professor, Centre for Science, Technology and Society, School of Habitat Studies at Tata Institute of Social Sciences (TISS), the study raises doubts about the efficacy of SPCBs but finds no evidence to support new regulatory bodies in the form of the National Environmental Protection Authority or the National Environment Assessment and Monitoring Authority proposed by the Ministry of Environment and Forests (MoEF).
Apart from unqualified political appointees, the SPCBs are understaffed and have little time for meetings, inspection or regulation, says the study. Chairpersons remain symbolic and data shows that except in Arunachal Pradesh, Chhattisgarh, Goa, Nagaland and Tripura, the average tenure of the chairperson in all other SPCBs has been less than three years. Though it is mandatory for the SPCBs to meet at least once in three months, the study finds that the meetings have not been consistent and often not well attended. They also have less than 17 members stipulated under the law. Board members should have a three-year tenure which is rare.
The study found a shortfall in human, technical and financial resources and increasing political interference and inability of SPCBs to adapt to emerging environmental problems. Poor resources and increasing political interference created hurdles in implementing environmental standards and norms effectively at the grassroots level, the study concludes.
The TISS study was conducted in March-June 2012 and analysed data from RTIs, reports and interviews. Even earlier studies pointed to environmental regulatory bodies facing a number of challenges such as lack of resources and increasing political interference in the performance of their statutory duties.
No industry can be set up without prior permission from the SPCBs that mainly regulate air and water quality and also approve locations for industries and conduct inspections or determine effluent standards for waste, among other duties. The Central Pollution Control Board in June 2006 said there were 2672 highly polluting industries and more than 1551 industries were not complying with norms laid down by SPCBs. Inspections are not conducted to check compliance as stack tests are rarely conducted. According to MoEF, Small and Medium Enterprises (SME) contribute to 70 per cent of the environmental pollution load in India.
Many States have not increased the staff strength of the SPCBs and report many vacancies. For example the study quotes a media report saying Kerala still operates with the staff strength it had been allocated in 1995, though new areas like municipal solid waste management, biomedical waste and high-rise buildings have been brought under its ambit. Of the sanctioned strength of around 320, 150 remain vacant. A committee appointed by the Supreme Court had recommended sanctioning 20 additional posts to the Kerala SPCB around six years ago, but nothing has been done so far.
Shortage of staff is a serious issue and Bihar, Chhattisgarh and Odisha SPCBs have not recruited even one person in the last five years. While environmental engineers and scientists have been recruited, these appointments are contractual and the salary is so low that most of them either leave or work under tremendous pressure.

The flood situation in two Godavari districts of coastal Andhra continued to be grim with hundreds of villages marooned, and the Met Office has forecast more rain over the next two days.
A large number of villages in East Godavari and West Godavari districts in coastal Andhra remained under water as the Godavari river continued to be in spate while the level has receded at upstream Bhadrachalam in Khammam district, officials said.
The water level in Godavari river at Sir Arthur Cotton Barrage at Dowleswaram crossed 17-foot mark on Monday morning and the outflow through all 175 gates reached a whopping 18 lakh cusecs, flooding the 'Lanka' villages, as the island villages in Konaseema region are called.

The floods in the two Godavari districts have hit over 1.5 lakh people. Many villagers are going without food and water. Over 5,000 people were shifted to relief camps and safe places, officials said.
Several villages in flood-hit Khammam, Karimnagar and Adilabad districts of Telangana region were still cut off.
North Telangana, which received some respite from heavy rain for the last two days, is facing a fresh threat with the forecast of more rain over the next two days.
Parts of Warangal, Adilabad, Karimnagar and other districts received heavy rain Monday. Intermittent rain also continued in Hyderabad.
The rain and floods over last one week have claimed 12 lives. Revenue, Relief and Rehabilitation Minister Raghuveera Reddy told reporters in Hyderabad an ex-gratia of Rs.2 lakh each will be paid to the families of the victims.
He said the rains have damaged 5,204 houses. More than 8,000 people have taken shelter in the relief camps opened in the flood-hit districts.
Electricity supply to 804 villages was disrupted and restored in 480 villages. The heavy rain and floods have damaged crops over 60,000 hectares. Reddy said 294 tanks had breached.
Krishna, the other major river that flows through the state, is also receiving huge inflows from upstream areas in Karnataka. The water level in Jurala project in Mahabubnagar district rose to 317.6 feet. Authorities have opened 13 gates to release the water. The outflow is reaching Srisailam dam.
This has raised the hopes of farmers in Krishna delta in downstream Krishna, Guntur and Prakasam districts.
The state has so far received 29 percent excess rainfall this monsoon. Officials said 13 districts have received excess rainfall this season while it was normal in eight districts. Only Anantapur and Visakhapatnam districts have received deficit rainfall.
 

Good agriculture practices can control environment degradation

NAGPUR: The ever-increasing environmental degradation can be attributed to various causes. But human or anthropogenic activities are the biggest culprits. Yet it is science and technology developed by man which alone can restore the environment. And good agriculture practices and use of biotechnology can play a very big role in this direction.
These views were expressed by Raviprakash Dani, vice-chancellor of Panjabrao Deshmukh Krishi Vidyapeeth ( PDKV) here on Wednesday. He was delivering the Ashok Juwarkar memorial lecture organized by National Environmental Engineering Research Institute (Neeri). Juwarkar was a senior institute scientist who died in a plane crash while on duty. He had conducted many environmental restoration projects, including the remediation of mine dumps of MOIL in Dongargaon.
The talk titled "Biotechnology and environmental reclamation: The agriculture factor" though focused on agriculture, it did raise issues of environmental pollution by industry, transport and domestic sources. Agriculture activities like excessive use of pesticides, fertilizers, illegal cleaning of forests besides pollution and degradation of soil, water and air have also reduced the biodiversity.
Dani suggested certain solutions for restoration of environment through minimizing use of pesticides and fertilizers, preventing soil erosion, phyto-remediation of contaminated soil, conversion of agri-waste into valued added products, development of new technologies to mitigate climate change and green house gases.
Biotechnology, Dani said, also can help mitigate environment pollution. Diseases and drought-resistant varieties, use of biotechnology in conservation of biodiversity, improving soil fertility through nitrogen fixing, bacteria use of genetic engineering and manipulations are some of the biotechnological methods of minimizing environment degradation. Biotechnology, he said, could also be used for reclamation of toxic waste sites.
He advised scientists to pursue research which is justified by community and revisit their research work regularly based on the updated information and changed circumstances. He emphasized on the need for community managed sustainable agriculture.
Earlier, Satish Wate, Neeri director, apprised the gathering of various achievements of the institute in the recent past. He stressed on the need for proactive research to solve pollution-related issues. He said the research work done by Dr Juwarkar laid a new foundation in the area of agriculture and environment, and Neeri is continuously progressing in this area.
Jaya Sabjiwale conducted the proceedings while Prakash Kumbhare, head, R&D Planning Division, proposed a vote of thanks.

EETD Scientists Develop Effective Approaches for Removing VOCs from Indoor Air

EETD Scientists Develop Effective Approaches for Removing VOCs from Indoor Air

Researchers estimate that those of us in developed countries spend 90 percent of our time indoors, which means that most of the time we are breathing air polluted by emissions from indoor sources. Providing more outdoor air ventilation can improve indoor air quality; however, energy is needed to heat, cool, humidify or dehumidify, and sometimes filter the ventilation air brought indoors from outdoors. Studies have shown that about 10 percent of the energy consumed in U.S. commercial buildings is used to thermally condition ventilation air. To improve a building's energy efficiency, we would like to reduce ventilation rates while maintaining good air quality—or better yet, to do so while improving indoor air quality.
Scanning Electron Microscopy images of synthesized catalyst LBNL-100 and of commercial MnO2

Through their work at the Indoor Environment Department of Lawrence Berkeley National Laboratory's Environmental Energy Technologies Division (EETD), William Fisk, Hugo Destaillats, and Meera Sidheswaran are devising solutions to this challenge. Recently, they have been evaluating two ways to reduce indoor air pollutants without increasing ventilation rates: by developing a synthetic catalyst to reduce indoor formaldehyde concentrations, and by evaluating the effectiveness of activated carbon fiber filters in reducing other volatile organic compound (VOC) concentrations.

Tackling Formaldehyde with a Manganese Oxide Catalyst

Formaldehyde is a common indoor pollutant that the World Health Organization and the U.S. Department of Health and Human Services lists as a human carcinogen. Formaldehyde concentrations in indoor air are routinely above the maximum recommended indoor level, so efforts to improve indoor air quality often target formaldehyde.
"Mean formaldehyde concentrations in a typical U.S. building are about 17 parts per billion," says Destaillats, "although 20 to 50 parts per billion are fairly common." The California Environmental Protection Agency guideline for the maximum recommended long-term-average formaldehyde concentration is 9 parts per billion.
To reduce these formaldehyde concentrations, Fisk, Destaillats, and Sidheswaran developed a catalyst that could be applied to the filters routinely used to remove particles from airstreams. They formed the catalyst samples by co-precipitation of manganese-containing precursors, and cured them at different temperatures to compare their effectiveness. The synthesis resulted in a black powder containing agglomerates of particles smaller than 50 nanometers (nm) in diameter, giving the formaldehyde plenty of surface area with which to react. The research team used porosimetry and surface area analysis; X-ray diffractometry; SEM imaging analysis; and ICP-MS analysis to characterize the catalyst.
"Surface area and porosity are important for good reactivity with the formaldehyde," explains Fisk, "but the manganese oxide can also have a variety of crystal structures and chemical compositions that influence their effectiveness as a catalyst."
The team applied the catalyst to particle filters, passed air containing formaldehyde and other contaminants through the filters, and measured the formaldehyde removal rates by the treated filter over time. Experiments were performed with various air speeds and with variable humidity. For reference, they also tested a commercially available manganese oxide under the same conditions.
The results have been encouraging. With air velocities typical of those in particle filtration systems, the initial formaldehyde removal efficiency was 80 percent; and even after 2,300 hours of continuous operation, the formaldehyde removal efficiency was approximately 60 percent.
"Typically, particle filters are replaced approximately every 1,500 hours of ventilation system operation, so the catalyst remains effective over the necessary time frame," says Destaillats. "The catalyst is inexpensive enough to be able to deploy it on particle filters and not have to recover the material when the filter is changed out every three or four months," says Fisk.
The synthesized sample that was conditioned at 100°C (LBNL-100) performed significantly better than the commercial sample. In fact, even when the amount of the commercial catalyst used was three times that of the LBNL-100 catalyst, the LBNL-100 catalyst still performed better, showing consistent single-pass formaldehyde removal of > 80 percent—far outperforming the commercial catalyst, which removed only 5 to 10 percent of formaldehyde over four days. Tests currently under way have shown that the LBNL catalyst also removes other VOCs.
Destaillats and Fisk attribute the effectiveness of the LBNL-100 to its higher available surface area, and its intrinsic redox properties seem to contribute to its much-longer effective lifetime, compared to the commercial version."The synthesized catalyst has a much higher surface area, and a different particle size and chemical composition than the commercial product, which results in superior performance," says Fisk.
In a separate set of experiments, measurement of upstream and downstream formaldehyde and CO2 concentrations showed that mineralization (breakdown of the formaldehyde into CO2 and water) in both experiments reached 100 percent, without formation of formic acid, a potential by-product of an incomplete reaction."This indicates to us that the catalyst should be able to achieve complete mineralization in buildings with the typical level—tens of parts per billion—of formaldehyde," says Destaillats." Preliminary tests at high velocities indicate that particles from the catalyst are not being entrained into the airstream.
Relative humidity has minimal effect on the effectiveness of the LBNL-100 catalyst. High relative humidity (90 percent) slightly reduced its formaldehyde removal efficiency, but its efficiency returned once relative humidity levels were reduced.
The 60 to 80 percent formaldehyde removal efficiencies are more than adequate. In fact, even a 20 percent formaldehyde removal efficiency in the supply airstream in a commercial building ventilation system could counteract the expected indoor formaldehyde increases associated with a 50 percent reduction in minimum outdoor air supply.
In some commercial buildings, this formaldehyde control could, by itself, enable energy-saving reductions in ventilation rates. However, in many situations the catalyst-treated filters would need to be supplemented by air cleaning systems or by pollutant source control measures for other pollutants. That approach could result in improved indoor air quality and simultaneous, significant ventilation energy savings. One very promising approach is to use activated carbon fiber air cleaners to remove other air pollutants.

Activated Carbon Fiber (ACF) Filters Prove Effective in Removing VOCs

While formaldehyde is a key indoor air pollutant, high concentrations of other VOCs in indoor spaces also pose health risks and inhibit the ability to decrease ventilation rates and energy use. In a separate study focusing on reducing ventilation and energy consumption while maintaining or improving indoor air quality, Fisk, Destaillats, and Sidheswaran evaluated the use of a commercial activated carbon fiber (ACF) media as a filter for cleaning air in heating, ventilating, and air conditioning (HVAC) systems.
Volatile organic compounds in the air flow adsorb to the ACF filter, removing them from the indoor air. To create space on the filter for more VOCs to adsorb, the VOCs must be desorbed from the filter periodically and exhausted outdoors—a process known as "regeneration." The research team studied three different regeneration methods for the filters, using outdoor air under ambient conditions, with humidified air, and with the filter or regeneration air heated. The best performance occurred when the ACF filter was regenerated for 15 minutes once every 12 hours using air heated to 150°C. The air flow during regeneration is only 1 percent of the airflow during the 12-hour period of air cleaning, so only a very small amount of air must be heated, and the amount of energy required for regeneration is small.
The research team studied ACF system performance with mixtures of VOCs, with VOC properties ranging from those of formaldehyde (with a molecular weight of 30 and a boiling point of -21°C) to undecane (with a molecular weight of 156 and a boiling point of 196°C). For all VOCs other than formaldehyde, the time-averaged VOC removal efficiency was above 70 percent. The efficiency of formaldehyde removal was approximately 20 percent. However, using a double layer of the ACF cloth, the efficiency of formaldehyde removal jumped to 40 percent, and the efficiency for other VOCs exceeded 90 percent. The ACF system imposed a low airflow resistance, so the system will have only a minor impact on fan energy use.
Modeling indicates that the combination of ACF air cleaning and a 50 percent reduction in ventilation can decrease indoor concentrations of VOCs by 60 to 80 percent and reduce formaldehyde concentrations by 12 to 40 percent. Thus, the system reduces exposures to VOCs and formaldehyde, while allowing the ventilation rate to be cut in half to save energy
"Energy modeling indicated the potential to reduce the energy required for heating and cooling of ventilation air by 35 percent to almost 50 percent," says Sidheswaran.

Ongoing Work Looks at Associated Issues

Fisk, Destaillats, and Sidheswaran continue to evaluate both solutions; looking at the catalyst's lifespan, the effect of other VOCs on its effectiveness, and its ability to remove other VOCs, as well as a combined approach that uses both the LBNL catalyst and the ACF filter.
"We're really pleased with the results on both products so far," says Fisk."Often when you work on something like this, things go wrong, but overall, our results here have been very satisfying."

Cool Car Colors Could Improve Fuel Economy, Reduce Emissions

Cool Car Colors Could Improve Fuel Economy, Reduce Emissions

Nearly all cars sold in California have air conditioners—the most energy-consuming car accessory. Cars painted with reflective coatings stay cooler in the sun and are easier to air condition to a comfortable temperature, according to a recent study by researchers in Lawrence Berkeley National Laboratory's (Berkeley Lab's) Environmental Energy Technologies Division.
"Solar reflective paints can decrease the 'soak' temperature of the air in a car that has been parked in the sun," says Ronnen Levinson, scientist in the Heat Island Group and lead author of the study."This could improve the vehicle's fuel economy by letting the manufacturer install a smaller air conditioner that draws less power from the engine."
White, silver, and other light colors are coolest, reflecting about 60 percent of sunlight. However, the study showed that dark "cool colors," which reflect primarily in the invisible "near infrared" part of the solar spectrum, can also stay cooler than traditional dark colors.

Soaking in the Sun

In the study, researchers parked two nearly identical Honda Civic four-door sedans, loaned by the California Department of General Services, in a lot in Sacramento, California. One was silver, and one was black. The shells (opaque elements) of the black and silver cars had solar reflectances of 0.05 and 0.58, respectively (on a scale of 0 to 1). Higher solar reflectance keeps a surface cooler in the sun.
Testing black and silver colored cars in a parking lot.
Figure 1. Black and silver experimental vehicles parked facing south in Sacramento, California, on July 17, 2010.
During the course of a sunny summer day, the cars were run through five identical cycles of soaking in the sun. Each cycle consisted of an hour with the air conditioners off, followed by a half hour of cooling with the air conditioners running at maximum. The researchers continuously measured the roof, ceiling, dashboard, windshield, seat, door, vent air, and cabin air temperatures in each car, as well as the external weather conditions in the lot.
At the peak of the soak phases, the roof of the silver (high reflectance) car was as much as 25°C (45°F) cooler than the roof on the black (low reflectance) car. The study found that increasing the solar reflectance of the car's shell by about 0.5 lowered the "soak" temperature of cabin air by about 5°C to 6°C (9°F to 11°F).

Downsizing the Air Conditioner

The researchers developed a thermal model that predicted the air conditioning capacity (rate of heat removal) required to cool each vehicle to a comfortable final temperature of 25°C (77°F) within 30 minutes—an industry standard for vehicle air conditioner performance. Based on the experimental measurements, the analysis predicted that the capacity required to cool the cabin air in the silver car is 13 percent less than that required in the black car.
Temperature over time graph for black and silver cars.
Figure 2. Comparison of roof surface temperatures measured during soaking and cooling trials.
Using a vehicle simulation tool called ADVISOR, the research team modeled the effect of air conditioner capacity on fuel consumption and pollutant emissions in each of several standard driving cycles. These include an urban cycle, a highway cycle, and a transient driving cycle with numerous increases and decreases in speed. They combined these simulations with the output of the thermal model to estimate the potential energy savings and emission reductions from using solar-reflective car paint to downsize the air conditioner.
Their results suggest that replacing a traditional black paint, which has a solar reflectance of 0.05, with a typical cool-colored paint that has a solar reflectance of 0.35 would increase fuel economy by 0.24 miles per gallon (mpg) (1.1 percent). This benefit would result from using a smaller air conditioner that draws less power from the car's engine. The change would also decrease carbon dioxide emissions by 1.1 percent, and reduce other automotive emissions, including nitrogen oxides, carbon monoxide, and hydrocarbons, by about 0.5 percent.
Using a white or silver paint (with a solar reflectance of 0.60) instead of a black paint would raise fuel economy by 0.44 mpg (2.0 percent). It would also decrease carbon dioxide emissions by 1.9 percent and reduce other automotive emissions by about 1 percent.
A roughly one- to two-percent improvement in fuel economy, when scaled to the fleet of light-duty vehicles in the U.S., represents an eventual potential savings of billions of gallons of gasoline, if these design changes are adopted by the automotive industry.
This research was supported by the California Energy Commission's Public Interest Energy Research (PIER) Program, and the U.S. Department of Energy.

Increased Ventilation Rates in Office Buildings Can Bring Billions of Dollars in Savings

Current standards for U.S. offices require approximately 8 liters per second (L/s) of outdoor air ventilation per person. Providing twice as much ventilation would reduce sick building syndrome symptoms (SBS) and absences, improve work performance, and result in billions of dollars in annual economic benefits in the U.S., according to a recent study from Lawrence Berkeley National Laboratory (Berkeley Lab).
Glass skyscrapers in a city.
A second study found that four remedial measures in U.S. offices—increasing low ventilation rates, improving temperature controls so that offices don't get too hot in winter, performing dampness and mold remediation, and adding economizers—would reduce adverse health effects and health care costs, decrease absence rates, improve thermal comfort, and improve work performance. The projected societal economic benefits of non-overlapping combinations of these remedial measures range from $17 billion to $26 billion per year.
These are among the conclusions of scientists at Berkeley Lab's Environmental Energy Technologies Division reported in two recently published journal articles.

Two Studies Examine Costs and Benefits

Two articles describing the results were published in the peer-reviewed journals Indoor Air and Building and Environment.
The Indoor Air article estimates the benefits of selected improvements in indoor environmental quality (IEQ) in U.S. offices compared to the existing level of IEQ in U.S. office buildings. They studied four improvements:
  • Increasing ventilation rates when they are below 10 or 15 L/s per person, (the current major standard in the U.S. specifies 8.3 L/s per person; 10 L/s is prevalent in other countries).
  • Adding outdoor air economizers and controls where absent. Economizers are control systems that increase the supply of outdoor air (the ventilation rate) above a minimum value when the additional ventilation will reduce the energy costs of air conditioning.
  • Avoiding office overheating—eliminating winter indoor temperatures greater than 23°C (73°F)—accomplished through adjustments in thermostat setpoints and other measures.
  • Reducing dampness and mold problems—accomplished through better maintenance to prevent and fix water leaks, changes in design and construction practices, and improved humidity control systems in some buildings within hot and humid climates.
The authors created scenarios and evaluated the impacts of improving existing IEQ conditions with equations derived from research on how IEQ parameters affect SBS health symptoms, absence, and work performance. They also used EnergyPlus, a building simulation model developed by Berkeley Lab, to estimate how the addition of economizers would affect ventilation rates and building energy use.
"The estimates of health benefits rely on dozens of studies of the relationship of IEQ with health, absence, and office work performance," says William Fisk, the principal investigator and head of the Indoor Environment Department. The benefits from these four improvements in office building IEQ are the result of small increases in work performance, reductions in absence, and decreases in health care costs spread over a large population of workers.
"The estimated annual benefits of increased ventilation rates (increased outdoor air supply) in offices are as high as $22 billion," says Fisk, "with annual energy costs less than $0.1 billion." The addition of economizers was a particularly attractive method of increasing ventilation rates. Projected net benefits are $12 to $22 billion, annual energy cost savings are $0.2 billion, and annualized implementation costs are also $0.2 billion, according to the research.
The study found that the estimated benefit of avoiding office overheating is $3.4 billion. Avoiding overheating prevents 7.7 million weekly sick building syndrome symptoms during winter, improves wintertime work performance on average by 0.2 percent, reduces winter dissatisfaction with thermal comfort by 12 percent among 40.4 million workers, and saves energy (not quantified in this study). The annual implementation cost is estimated at less than $0.4 billion.
The estimated annual benefit of reducing dampness and mold in offices is $0.5 billion, resulting from the elimination of 1.5 million days of absence.

Focus on Ventilation Rate Changes

The second article, appearing in the journal Building and Environment, estimates the benefits of increasing ventilation rates in U.S. offices, assuming that all existing offices have the minimum ventilation rate prescribed in the leading U.S. ventilation standard. The article is called "Changing Ventilation Rates in U.S. Offices: Implications for Health, Work Performance, Energy, and Associated Economics."
A body of prior research has shown that higher ventilation rates decrease indoor air pollutant levels, improve satisfaction with indoor air quality, lower SBS symptoms in office workers, and improve work performance. Some research also suggests that lower absence rates are linked to higher ventilation rates (VRs).
The study conducted by Fisk, Douglas Black of Berkeley Lab, and Gregory Brunner of the U.S. Environmental Protection Agency, assumed a baseline ventilation rate in U.S. office buildings of 8 L/s, which is slightly below the current ventilation rate recommended by ASHRAE (Association of Heating, Refrigeration, Air Conditioning Engineers). Eight liters of air per second is about 16 cubic feet per minute. ASHRAE sets voluntary minimum standards for buildings, and ventilation standards are designed to prevent high concentrations of indoor pollutants.
Two scenarios assumed that ventilation rates increased from 8 to 10 L/s per person and from 8 to 15 L/s per person. The third scenario assumed that ventilation rates decreased from 8 to 6.5 L/s per person. In a fourth scenario with an 8 L/s per person minimum ventilation rate, economizers were added to the 50 percent of U.S. office floor space in buildings that do not have them.
The result showed that with a 25 percent increase in ventilation rate to 10.0 L/s per person, the total economic benefit was $13.0 billion, and the estimated annual energy cost was $0.05 billion. The estimated benefits include prevention of SBS symptoms in half a million workers, elimination of 9.4 million days of short-term absence, and an average 0.3 percent increase in work performance.
With a 90 percent increase in ventilation rate to 15.0 L/s per person, the research showed a total benefit of $37.5 billion, at an estimated annual energy cost of $0.19 billion. The increased ventilation rate prevented SBS symptoms in 1.4 million workers, eliminated 30 million days of short-term absence, and increased work performance on average by 0.9 percent.
With a minimum ventilation rate of 8 L/s per person, adding economizers to buildings that do not have them was projected to save $0.32 billion in energy costs each year. In this scenario, the measure prevented SBS symptoms in 1.2 million workers, prevented 28 million days of short-term absence, and increased average work performance by 1.6 percent. The total annual economic benefit was estimated at $32.9 billion.
The benefits are again the result of small increases in work performance, reductions in absences, and decreases in health care costs spread over a large population of workers.
"Our study shows that the widespread benefits of increasing ventilation rates in office buildings far outweigh the energy costs by an order of magnitude, says Fisk, "and increasing the use of economizers in more commercial buildings would retain the benefits of higher VRs as well as result in energy savings."
Fisk cautions that there are several uncertainties in this study."Our understanding of how ventilation rate affects health, performance, and absence is the main source of uncertainty," he says.
"The value of this study to building owners and energy managers, architects and engineers, and policy makers is that, although there are uncertainties in the absolute magnitude of health benefits and energy costs, the study has shown that the economic benefits from improved health, reduced absenteeism, and improved work performance are far higher than the implementation cost."
"Most importantly," Fisk concludes, "there are opportunities to improve the health of building occupants and save on costs while reducing energy use simultaneously."

Based on the successes on NRM technologies ( like water harvesting and recycling, construction/renovation of water bodies, watershed management, agroforestry / afforestation, vermicomposting / enriched composting etc), an ICAR-RD interface has been initiated for generation of rural livelihoods through creation of employment under NREGA.
An extensive programme on 'More crop and income per drop of water " funded by Ministry of Water Resources in participatory mode has been launched for the conservation and better utilization of rain water in rainfed areas. A special programme on scaling up of water productivity in Agriculture for livelihood through teaching cum demonstration has also been taken up.
Besides, based on the NRM findings, several important policy decisions namely nutrient based fertilizer subsidy, customization/fortification of fertilizers with micro & secondary nutrients, revival of SSP etc. have been made to ensure balanced fertilization in the country.
Future Outlook :
Sustainable management of natural resources is vital as agricultural development with positive growth and long term sustainability cannot thrive on a deteriorating natural resource base. We are today, confronted with widespread land degradation, ground water imbalances, impaired soil health and contamination of food and environmental pollution etc. The situation is getting further compounded with the recent climate change impacts on agriculture. To have a holistic solution to these emerging problems, the division has set future priority research on abiotic stress management (droughts, cold waves, floods, salinity , alkalinity, acidity and nutritional disorders etc ), climate resilient agriculture, conservation agriculture including organic farming, bioremediation of contaminated soils and water, biofortification, biofuels, bio-industrial watersheds and development of decision support systems for micro level land use planning etc.
Another research priority domain is applications of nanotechnology to enhance nutrient and water use efficiency and development of bio-censors for soil quality assessment etc.

Soil Quality Evaluation: An increasingly felt issue in agriculture

Soil Quality Evaluation: An increasingly felt issue in agriculture
Although soil has evolved through millions of years of weathering and is sustaining various forms of terrestrial life, its management has become an essential component of strategy for sustenance of ever increasing population. Assessment of soil quality is prerequisite for devising any intervention(s) in the existing management practices so as to achieve the desired goal. It focuses on the dynamic or management-affected, properties of soil, which are assessed in the context of its inherent capability. Soil quality cannot be measured directly because it is a broad and purpose-oriented concept. Instead, we analyze a variety of proxy measurements (called indicators) that together provide clues about how the soil is functioning as viewed from soil-use perspectives, which are subsequently integrated to arrive at certain numerical value that is indicative of overall quality of soil. Although importance of soil quality evaluation has not been realized in the era of high input dependent agriculture, rising cost of fertilizers/manures, decreasing availability of irrigation water and increasing impact of industrial activity on land are compelling us to devise policies based on soil quality.
Since the origin of this concept in early '90, several workers both in India and abroad have made efforts for identifying indicators for assessing the quality of soil within certain boundary conditions using several techniques, which can be grouped into two broad categories. In the first category, statistical techniques are employed for identification of indicators influencing goal variable (e.g. crop yield, produce quality etc.). As selection of indicators is based on the goal variables, experiments are required to be conducted under controlled condition for eliminating/minimizing influence of other factors not related to soil (like microclimate, disease/pest infestation & control, seed quality, irrigation water amount and quality etc.). Under this background, identification of indicators of soil quality on the basis of crop yield data generated from farmers' fields may not give a true picture. Information generated under an on-going NAIP project has also revealed that many of the important soil parameters known to have strong influence on crop growth did not figure-in as identified indicators and as a result, quite a lower degree (28%) of the variability in yield could be explained by the indicators of soil quality. The result also showed that soil quality index (SQI) values derived from the identified indicators for any agro-ecological sub-region (AESR) were not comparable with SQI values of other AESRs of the country.
Other group of workers/organizations has proposed indicators of soil quality based on the knowledge pool generated through detailed investigations on soil properties and its functions. Soil quality index computation based on this approach appears to be very simple and can be easily adopted by soil testing laboratories. Although this approach appears more appropriate, difficulty arises while deciding upon (1) contribution of each of the indicators towards goal variable, (2) whether a similar set of indicators is applicable to all soil types, cropping types (like annual, perennial or horticultural) and management conditions or otherwise. Detailed investigations as well as thorough discussions are required among peer groups on these issues.

NEEM OIL & NEEM COATED UREA
The neem coated urea , a slow release fertilizer was included under Schedule- I Part –A of the Fertilizer Control Order.

Neem oil or Margosa oil is botanical oil extracted from kernel of neem tree seed by Cold Pressing or CT Cold Pressing method or Solvent Extraction. Among these methods CT cold pressing yield purest neem oil because solvent is not used for extraction.

Properties of Neem Oil:

Neem Oil or Neem Seed Oil is a Brownish Yellow color Liquid, with smell of Garlic. Neem Oil is slightly soluble in water and has 6.5 to 7.5 pH value, it boils at more than 200 degree Celsius and freeze at 13 degree Celsius.

Uses of Neem Oil:

For Agriculture Use:
Neem Oil is used to manufacture neem oil insecticide because it contains azadirachtin which effects over 600 species of pests including insects, nematodes, fungi and viruses and is completely safe to non target organisms like beneficial predators, honey bees, pollinators, fish, birds, cattle and human beings.
Azadirachtinof neem oil is a famous natural Anti-feedent, growth regulator and ovi-positional repellent for insects, as a major active ingredient which make it a perfect alternative to chemical pesticides.
For Pets Use:
Neem Oil is used as Veterinary Medicines for Pets and Live Stock from ancient time. Ozoneem Oil is used in various diseases, precautions, accidental condition, hygiene and wounds as an ingredient of medicines or alone.
For Human Medicines:
Neem Oil is also used as and in various medicines for human beings. Most common utilities are: Birth Control, Lice Control (in hairs), Piles, Ulcers, Asthma, Skin Disorders, Chronic Diarrhea.
Cosmetics :
Neem Oil is used for preparation of various cosmetic and toiletries. All Purpose Cream, Hair Oils, Tooth Paste, Bathing Soaps, Hair Shampoo, Face Pack, Dog Shampoo
Urea is the major fertilizer used in the world as a nitrogen supplier which is a criitical nutrient for crop growth. Urea contains highest nitrogen content of all solid nitrogenous fertilizers currently available.
Nitrogen use efficiency in rice is hardly 40 %, even under well managed conditions. Fertilizer materials that are better than prilled urea should be promoted to get a higher fertilizer use efficiency. There is a considerable potential to improve the N use efficiency by promoting neem coated urea.
Nitrogen from Urea is released in the soil and water and leached by activity of nitrifying bacteria NItrobactor and Nitrosomonas. These bacterias turn nitrogen in nitrite and then nitrate which are highly mobile in nature when present in soil. By these processes approximate 50% of nitrogen provided by urea is lost.
Solution to this problem of nitrogen loss of urea is to coat the urea with a substance that can prevent bacterial activity of nitrification.
Neem Based Urea Coating Agent
Why to use neem as urea coating agent?
Neem has proven nitrification inhibition properties. This way it slow down the process of nitrogen release from urea. It is the best nitrification inhibiting agent till date and better then sulpher.
Benefits of Neem Coated Urea
  • 1. Slow Down the process of nitrification of urea.
  • 2. Enhance the yield by 48%.
  • 3. Decrease urea requirement, hence save Money.
The nitrogen (N) fertilizer-use efficiency (20–50%) is low in rice fields in India. The neem-oil coated urea can increase N-use efficiency in lowland rice, but the desirable thickness of neem-oil coating onto urea is not known yet. Therefore, field experiments were conducted during kharif (rainy) season years 2004 and 2005 at the Research Farm of Indian Agricultural Research Institute, New Delhi to know the suitable thickness of neem-oil coating on prilled urea (PU) for increased N-use efficiency and yield. The treatments comprised of twelve combinations of four N sources (PU coated with neem-oil thickness of 0, 500, 1000 and 2000 mg kg−1 PU) and three N levels (50, 100, and 150 kg N ha−1) plus a no-N control. Prilled urea (PU) refers to the common urea available commercially in prills, which is different from urea super granules. Application of urea coated with neem-oil thickness of 1000 mg kg−1PU resulted in significantly higher growth, yield parameters, grain yield, N uptake, and efficiency of aromatic rice (Oryza sativa L.) over uncoated PU. Nitrogen application at 122 kg ha−1 was optimum for increased yield of rice. Nitrogen-use efficiency decreased significantly and substantially with each successive increase in levels of N from 50 to 150 kg ha−1.





NEEM COATED UREA: A STEP IN RIGHT DIRECTION. MORE NEEDS TO BE DONE:

By: Dr. B. N. Vyas - GM, Research & Technical Development,
Godrej Agrovet Ltd., Pirojshanagar, Eastern Express Highway, Vikhroli, Mumbai – 400 079 India



With limited scope for horizontal expansion in the net cultivable area due to demands of an ever-increasing population, it is essential that highly efficient management practices and modern scientific techniques are adopted to increase agricultural production in India. Efficient water and nutrient management are the key elements of intensive agriculture. At the current use levels of primary nutrients (N, P, K) of 20 million tons, almost two thirds of this quantity is accounted for, by nitrogen alone.  Globally, nitrogenous fertilizers are produced in 72 countries, the total production being 94 million tons in 2002–03 as compared to nearly 50 million tons in 1970.  Forecasts suggest that the consumption of nitrogenous fertilizers is likely to rise to 134 million tons in the next decade
.

It is worthwhile to note that urea constitutes nearly 80% of the total straight nitrogenous fertilizer consumption in India. In quantity terms nearly more than 20 million tons of urea is used in India currently, and it is safe to presume that urea would continue to maintain its predominant position among nitrogenous fertilizers.  On the other hand, globally, due to use of other nitrogenous fertilizers, namely, liquid ammonia, ammonium sulphate and ammonium nitrate, the contribution of urea usage is less than half of the total nitrogenous fertilizers.

Urea Transformations:

Under the environmental conditions encountered in most parts of India, urea after application to soils hydrolyses fairly rapidly to ammonium carbonate, over a maximum period of about a week. The ammoniacal form of nitrogen is subsequently converted to nitrite and then to nitrate by the action of nitrifying bacteria viz. Nitrosomonas sps. and Nitrobacter sps., respectively. The processes of hydrolysis and nitrification of urea fertilizer are to a large extent completed in about 15–20 days under most agroclimatic conditions. In this context, it should be noted that the duration of most cultivated crops extends beyond 90–100 days, and therefore, nitrates formed as a result of the relatively rapid hydrolysis and nitrification of urea being highly soluble, and in excess of the limited quantities required by the crops at their early stages of growth are liable tobe leached down the soil profile, beyond the active root zone of crops.  Moreover, under waterlogged conditions nitrates are reduced to elemental nitrogen and nitrous oxide by the action of denitrifying bacteria to meet their oxygen demand.  This leads to the development of nitrogen deficiency and poor crop yields.  In view of this it is most important that fertilizer use efficiency needs to be improved to make fertilizer use economically viable and more attractive.

Scientists around the world are concentrating their efforts on regulating the nitrogen supply to crops by reducing the rate of either hydrolysis or nitrification or both, so as to ensure continuous and optimal supply of nitrogen to match the requirements of crops at different stages of growth. A considerable volume of data is available on the potential of the constituents of neem (Azadirachta indica) seeds known as triterpenes as effective nitrification inhibitors. In fact the Indian Council of Agricultural Research in its publication ‘Technology for Rice Production’ for different states has recommended the use of neem cake blended or coated urea. In spite of the encouraging results obtained with the use of urea coated with neem cake, this practice has not attracted the attention of farmers on a large scale because the process of coating urea with neem cake is cumbersome and because neem cake is not readily available at the farm level.

Industrial Developments:

During late eighties and early nineties, some industries including M/s. Godrej Agrovet Ltd. developed ready to use neem extracts containing neem triterpenes which could be mixed with urea straight away to obtain the neem coated urea (NCU), thus eliminating the use of neem cake and coal tar and other additives. Neem coated urea produced using concentrated extracts were extensively evaluated under large field trials and were found to show great yield improvements. At this stage it was envisaged that neem coated urea could be produced by urea manufacturers, however, urea being controlled under Essential Commodity Act and Fertilizer Control Order, a special permission by concerned Ministry was required to produce and market fortified urea (neem coated urea) fertilizer.


Since this exercise was going to take quite sometime, as an interim arrangement, manufacturers started marketing neem based urea coating agents in the market and farmers were advised to mix urea coating agent with urea before application. Currently, more than 20 entrepreneurs sell such neem based urea coating products in the market
.

Industry Representation:
 
Since production of neem coated urea at urea manufacturing location was the ultimate solution, the industry continued its efforts with Government of India to seek their approval for the endeavor.  At this stage Neem Foundation also joined the industry to serve the novel cause.  In fact a delegation under the leadership of Dr. R. C. Saxena, Chairman - Neem Foundation, met Mr. Suresh Prabhu, the then Minister of Fertilizers and Chemicals, Government of India with the following demands.


(i)    Inclusion of neem coated urea as accepted category of fertilizers in Schedule I of the Fertilizer Control Order.
(ii)    Subsidy component available for uncoated urea should also be available for neem coated urea.
(iii)    Grant of small premium in price of neem coated urea vis-à-vis uncoated urea in order to take care of the cost of coating agent and technology for coating urea with neem extracts.
(iv)    Directing fertilizer factories to coat at least 10% of their production with neem.

It is heartening to mention here that due to continuous efforts and perseverance of the Industry and Neem Foundation, Government of India finally on May 12, 2003, issued a notification indicating FCO Amendments to include specifications of neem coated urea to be produced by M/s. National Fertilizers Ltd. (NFL). However, it was clarified that Government of India has decided to permit all the manufacturers who wish to manufacture neem coated urea at their factories.


It may be pointed out here that only one out of the four demands listed above have been met. NFL, producer of neem coated urea are absorbing additional costs in their system and do not wish to seek additional selling price for their neem coated urea.


It would not be out of place to mention here that NFL produces neem coated urea by using very low quantity of neem oil emulsion, which is primarily aimed at prevention of caking and reduction in losses during storage.  Increase in yield upto 4-5% as claimed by producers (NFL) is considered incidental, whereas on the other hand the product developed by the industry is aimed at improvement in agronomic efficiency as primary objective and reduction in caking and losses during storage being additional advantage. As it has been established for several years, higher agronomic efficiency is attributed to presence of neem triterpenes for which products need to be specifically formulated. A efficacious and stable Neem coating product would certainly require price support from Government of India. 
 

Therefore, it is emphasized here that by granting permission to manufacture NCU, the authorities in India have taken one step in right direction. However much more needs to be done, if we have to really reap the benefit of this wonderful technological innovation.

In summary, the advantages of the neem coated urea can be enumerated as follows:

1.    Saving of 10% of the losses of urea would amount to 2 million tons of urea or a reduction in subsidy component to the tune of Rs. 1,200 crores per annum (considering total subsidy on urea to be Rs. 12,000 crores per annum).
2.    Proportional saving in the consumption of naphtha or natural gas.
3.    Increased crop yields due to better nitrogen utilization.
4.    Reduction in environmental pollution of ground water due to leaching of nitrates and gaseous emissions.   
5.    Opportunity for entrepreneurs to commercialize local Neem Resources and Development of Small Scale Industries in rural areas.

USE OF NON-UREA FERTILIZERS



16:39 IST




Government policy is to support balanced use of fertilizers to sustain soil health in the country.

The following steps are taken for the balanced use of fertilizers:

i. Nutrient Based Subsidy Policy, which has been implemented w.e.f. 1.4.2010, promotes competition amongst the fertilizer companies. The fertilizer companies tend to focus on farmers through farm extension services and educate farmers about the modern fertilizer application techniques, soil health and promote soil test based application of soil and crop specific fertilizers, which is necessary for balanced application of fertilizers.

ii. Use of customized fertilizers is encouraged with the objective to promote site specific nutrient management so as to achieve maximum fertilizer use efficiency of applied nutrient in a cost effective manner. These fertilizers are multi-nutrient carrier designed to contain macro and micro nutrients and are soil specific and crops specific formulated on the basis of soil testing results. The Government has also allowed the use of subsidized fertilizers for manufacturing mixture and customised fertilizers to promote use of customized fertilizers.

iii. Subsidy on sulphur content in the fertilizers is provided.

iv. To meet the requirement of micro nutrients, a fixed subsidy is also provided on fortification of fertilizers by Boron and Zinc. Use of Neem Coated Urea is also encouraged.

v. Soil test based balanced and integrated nutrient management through conjunctive use of both inorganic and organic sources (compost, manures, bio-fertilizers etc.) of plant nutrients is recommended to sustain sound soil health.

vi. Soil testing facility is provided to the farmers free of cost or with some nominal fee by State Governments. In this regard soil health cards are issued by the State Governments to farmers.

vii. A National Project for Management of Soil Health & Fertility has been launched during 2008-09. Under the project financial assistance is provided to set up new static Soil Testing Laboratories (STLs) and new Mobile Soil Testing Laboratories besides strengthening of existing laboratories.

viii. Indian Institute of Soil Science (IISS), Bhopal under ICAR has been sanctioned a project for preparation of Geo-Referenced Soil Fertility Maps including interlinking of soil fertility status with Soil Test Crop Response (STCR) data to generate site specific recommendations in 19 major States (171 districts).

This information was given by the Minister of State (Independent Charge) for Chemicals and Fertilisers, Shri Srikant Kumar Jena in a written reply in the Lok Sabha today.

What Scientists Are Seeing Over Antarctica 

 NASA's Operation IceBridge has launched its Antarctic 2012 campaign, flying high-priority missions measuring polar ice from a base of operations at the tip of Patagonia on the Strait of Magellan. They have even made a return visit to the Pine Island Glacier, the site of last year's discovery of a massive rift in the ice.

Sea ice doesn't always hold the allure of a massive ice sheet, or a crevassed blue glacier spilling between mountains, but it comes in array of shapes and sizes and has its own ephemeral beauty. Operation IceBridge studies sea ice at both poles, and also runs across interesting formations on route to other targets. Operation IceBridge returned to the Pine Island Glacier twice in 2012, and NASA glaciologist Kelly Brunt discusses the implications of the glacier's impending calving event.

Operation IceBridge has now returned to the Pine Island Glacier, not once, but twice in 2012. And the year-old giant crack in the glacier, poised to create an iceberg the size of New York City? Well it's still there, and that iceberg has yet to break free. But the rift has grown longer, much wider, and spawned a secondary crack. Before we talk about when that mighty berg will be born, let's take a look at the IceBridge missions themselves. IceBridge's first return to the region was a high altitude flight over the entire region, including the Thwaites, Smith, and Kohler glaciers. After this campaign is over, scientists will be able to compare this broad survey with previous years' measurements in order to better document the rapid and widespread changes in the region over time.
