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 …
Inter-Governmental Panel on Climate Change has shown that the earth temperature has increased by 0.74 degree C between 1906 and 2005 due to increase in anthropogenic emissions of greenhouse gases. It is estimated that crop production loss in India by 2100 AD could be 10-40% despite the beneficial effects of …
Atmospheric nitrogen oxides (NOx =NO+ NO2) play a pivotal role in the cycling of reactive nitrogen (ultimately deposited as nitrate) and the oxidative capacity of the atmosphere. Combined measurements of nitrogen and oxygen stable isotope ratios of nitrate collected in the Arctic atmosphere were used to infer the origin and …
Pulses in India contribute less to global warming greenhouse gas emission during pulse cultivation in India is much less than in developed countries because of minimal use of nitrogenous fertilizers. India has just got a proof of it. Pulse crops are known to release nitrous oxide, a greenhouse gas, but …
Tropospheric NO2 concentrations derived from spaceborne measurements of Global Ozone Monitoring Experiment (GOME) on board ERS 2 and Scanning Imaging Absorption Spectrometer for Atmospheric Cartography (SCIAMACHY) on board Envisat, respectively, for the time period of 1996
There is a gradual increase in the concentration of greenhouse gases (GHGs)like CH4 and N2O in ambient air due to intensive agriculture, rapid industrialization and the expanding transport sector. About 80% of N2O is produced biologically and the major sources are agricultural fields, wetlands, sediments, animal wastes and landfills. Emission …

Molecular chlorine (Cl2) is an important yet poorly understood trace constituent of the lower atmosphere. Although a number of mechanisms have been proposed for the conversion of particle-bound chloride (Cl-) to gas-phase Cl2, the detailed processes involved remain uncertain. Here, we show that reaction of dinitrogen pentoxide (N2O5) with aerosol-phase …
Shipping is one of the most fuel-efficient ways to move freight, but the industry still produces significant greenhouse-gas emissions, including more than a quarter of the world's nitrogen oxides emissions. And it also produces more sulphur dioxide emissions than all land transportation combined. In the latest of Nature's our Future …
The effluent and emission standards for oil refineries were notified under Environment (Protection) Act in the years 1986 and 1990, respectively. These standards were same for old & new refineries and considered only few parameters. There was need to include additional parameters viz. Oxides of Nitrogen (NOx), Volatile Organic Compounds …
Indian scientists seek clarity on nitrogen emissions if emissions of reactive nitrogen gases (oxides of nitrogen and ammonia, but especially nitrous oxide) ever get hitched to the international debate on global warming, in the form of a
living close to main roads could put your child at risk. A study conducted by German researchers in the Munich metropolitan area showed that traffic- related pollution could be responsible for increasing the risk of allergy and respiratory diseases by more than 50 per cent in children. Parents were asked …
In the late 1980s and very early 1990s, when scientists worldwide began to highlight global warming as a problem that needed urgent attention, pointing to carbon dioxide from fossil fuel burning as the most potent cause, there emerged a counter-discourse that laid the blame of global warming squarely on another …
Dinitrogen (N2) fixation is widely recognized as an important process in controlling ecosystem responses to global environmental change, both today and in the past; however, significant discrepancies exist between theory and observations of patterns of N2 fixation across major sectors of the land biosphere. A question remains as to why …

The International Maritime Organization recently revised the MARPOL Annex VI so regulations are clearer and nitrogen oxides emissions are further reduced.
Given the intensity of agriculture and the position of environmental degradation in the country it is necessary to strike balance between fertilizer use and developmental goals for the achievement of economic and environment sustainability. The development could be possible only through judicious management of natural resources without losing much on …
Here the authors present results of the first multi-decadal experiment to examine the impacts of chronic, experimental nitrogen addition above ambient atmospheric nitrogen deposition. This total input rate is comparable to terrestrial nitrogen deposition in many industrialized nations. The researchers found that this chronic low-level nitrogen addition rate reduced plant …
The concentration of CO2 in the atmosphere is at its highest since the past 650,000 years, says the US National Oceanic and Atmospheric Administration. Between 1979 and 2007, the level of CO2, the primary driver of climate change, increased at an average rate of 1.65 parts per million. The growth …
