Agriculture is multi-functional, producing economic goods including food, feed, fibre, and fuel, as well as providing several intangible or non-tradable services to society free of cost. Non-tradable services, unlike economic goods, remain unpriced; as a result, farmers are not compensated monetarily for the benefits of the several non-tradable services they …
NEW DELHI: A thick haze over Delhi on Friday has set the alarm bells ringing over growing air pollution in the city. While pollution normally rises during winter, Friday's level at places was more than 10 times the prescribed limits. For instance, levels of oxides of nitrogen (NOx), the prescribed …
The world is undergoing a phenomenally fast wave of urban growth. Research that can help tackle some of the ensuing problems is likely to originate in cities themselves. (Editorial)
It is well demonstrated that the responses of plants to elevated atmospheric CO2 concentration are species-specific and dependent on environmental conditions. We investigated the responses of a subshrub legume species, Caragana microphylla Lam., to elevated CO2 and nitrogen (N) addition using open-top chambers in a semiarid temperate grassland in northern …
The Centre for Science and Environment had recently pointed out that continued heavy subsidisation of diesel had resulted in people shifting to buying of diesel vehicles. The subsidy on diesel had led to a situation where consumption by private vehicles — passenger cars and SUVs — exceeded consumption by the …
To check the increasing pollution levels in the country’s most polluted city, the Punjab Pollution Control Board (PPCB) has decided to study the vehicles’ contribution towards the problem in the city. For this purpose, the PPCB officials would be collecting samples of ambient air quality from five parts of the …
Lanco Infratech Limited (LITL), has announced that Lanco Tanjore Power Company Limited (Formerly known as Aban Power Company Limited) has won the Rajiv Gandhi Environment Award for Clean Technology for the year 2009-2010 in recognition to its contribution to cleaner production as well as its commitment towards environmental pollution control …
Health experts lamented a move by U.S. President Barack Obama to halt rules on limiting smog pollution, saying the decision could endanger many people already susceptible to respiratory problems. Under pressure from businesses and Republican lawmakers, the Environmental Protection Agency had delayed issuing a rule on ozone limits several times. …
Nitrogen (N) limits the productivity of many ecosystems worldwide, thereby restricting the ability of terrestrial ecosystems to offset the effects of rising atmospheric CO2 emissions naturally. Understanding input pathways of bioavailable N is therefore paramount for predicting carbon (C) storage on land, particularly in temperate and boreal forests. Paradigms of …
Ecosystems acquire nitrogen from the atmosphere, but this source can't account for the large nitrogen capital of some systems. The finding that bedrock can also act as a nitrogen source may help solve the riddle.

Kolkata is one of the most polluted cities of the world. The city has been plagued by one of the most prominent pollution problems of the of the world, the air pollution. The time period of 2000-2008 saw a huge number of vehicles hitting Kolkata’s streets, which has lead to …
An Autoricshaw ride in Delhi comes at a great cost, and not just for your pocket. A recent study conducted by Joshua Apte, a PhD candidate from the University of Berkeley, has found that a single trip in an autorickshaw in Delhi could expose you to levels of air pollution …
New Delhi: Ten years after the city’s public transport switched to CNG, air pollution has again become a major threat to public health in Delhi, say environmentalists. With 69 lakh vehicles plying on city roads, a growth of about 60 lakh in 20 years, experts say oxides of nitrogen (NOx) …
Ten years after the city’s public transport switched to CNG, air pollution has again become a major threat to public health in Delhi, say environmentalists. With 69 lakh vehicles plying on city roads, a growth of about 60 lakh in 20 years, experts say oxides of nitrogen (NOx) and particulate …
Dynamics of nitrous oxide (N2O) emission and the relationship of soil properties with N2O emission were studied from the tea ecosystem of North East India situated at north bank plain agroclimatic zone at Tezpur, Assam. The gas samples were collected from the tea bush at weekly intervals from 30 August …
This article reports the greenhouse gas emissions of anthropogenic origin by sources and removals by sinks of India for 2007 prepared under the aegis of the Indian Network for Climate Change Assessment (INCCA) (note 1). The emission profile includes carbon dioxide (CO2), methane and nitrous oxide.
Centre for Science and Environment (CSE) has welcomed and supported the move of finance minister Pranab Mukherjee to consider removing diesel fuel subsidy for diesel car owners. CSE has consistently raised its voice over misuse of public policy on fuel pricing inciting dieselisation, increasing toxic risk from diesel emissions, worsening …
Earth’s climate is warming as a result of anthropogenic emissions of greenhouse gases, particularly carbon dioxide (CO2) from fossil fuel combustion. Anthropogenic emissions of non-CO2 greenhouse gases, such as methane, nitrous oxide and ozone-depleting substances (largely from sources other than fossil fuels), also contribute significantly to warming. Some non-CO2 greenhouse …
There have been many studies on the effects of enriched levels of atmospheric carbon dioxide on soils. A meta-analysis shows that emissions of other greenhouse gases increase under high-CO2 conditions. http://www.nature.com/nature/journal/v475/n7355/full/475177a.html
Increasing concentrations of atmospheric carbon dioxide (CO2) can affect biotic and abiotic conditions in soil, such as microbial activity and water content. In turn, these changes might be expected to alter the production and consumption of the important greenhouse gases nitrous oxide (N2O) and methane (CH4). However, studies on fluxes …
