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 …
Rice (Oryza sativa L.) production is facing major challenges, including scarcity of irrigation water and ongoing climate change. Modifications of the current cropping techniques could increase yield, save water, and mitigate greenhouse gas emission. We investigated the effect of planting methods (young seedlings, wide spacing with alternate wetting and drying …
Attribution of Antarctic ozone recovery to the Montreal protocol requires evidence that (1) Antarctic chlorine levels are declining and (2) there is a reduction in ozone depletion in response to a chlorine decline. We use Aura Microwave Limb Sounder measurements of O3, HCl, and N2O to demonstrate that inorganic chlorine …
In September 2017, China’s Ministry of Environmental Protection issued the first national standard for portable emission measurement system (PEMS) testing of heavy-duty vehicles (HDVs). The regulation is a supplement to all existing requirements under the China V standard, and it requires additional on-road PEMS testing for new and in-use China …
Poor air quality is one of the leading five health risks worldwide, along with high blood pressure, tobacco smoking, diabetes and being overweight. In 2015, it contributed to nearly 8% of all deaths worldwide. Long-term exposure to polluted air has been linked to respiratory infections, chronic obstructive pulmonary disease, stroke, …
Nagpur: On Monday when the apex court observed Delhi's situation to be emergency-like, the air quality recorded in the industrial area of Chandrapur was even worse than the Capital. The average air quality index (AQI) of Chandrapur was recorded to be 500 while at most places in Delhi it was …
While parts of North India battle the life-threatening smog, there is some good news and some bad news. The good news is that apart from big cities, what the northern plains (including Punjab and Haryana) are witnessing is not smog but fog. And the bad news is that the weather …

It is estimated that about 1,000 units directly and nearly 10,000 allied units …
In response to global warming, the Brewer–Dobson circulation in the stratosphere is expected to accelerate and the mean transport time of air along this circulation to decrease. This would imply a negative stratospheric age of air trend, i.e. an air parcel would need less time to travel from the tropopause …
Green activist Sunita Narain on Thursday said the Environment Pollution Control Authority, of which she is a member, is determined to get a ban on petcoke import as the country should not become a dumping ground for the fuel from the US and other countries. "We have recommended a ban …
Noting that air pollution has reached crisis level in Northern India, government think-tank Niti Aayog has recommended a slew of measures like imposing higher taxes on petrol in and around the more polluted cities to encourage commuters to share cars and take public transportation. The Aayog, in its 'Three Year …
Nowadays, most of the research on air pollution and its adverse effects on public health in China has focused on megacities and heavily-polluted regions. Fewer studies have focused on cities that are slightly polluted. Shenzhen used to have a favorable air environment, but its air quality has deteriorated gradually as …
Scientists have developed a catalyst that can curb emissions of nitrogen oxides from diesel-powered vehicles, an advance that may help reduce air pollution and smog. Nitrogen oxides (NOx) is a priority air pollutant that is a key ingredient in smog. "Diesel engines power virtually all heavy-duty trucks, and NOx emissions …
Sixty three signatories from civil society organisations, medical professionals and concerned citizens all over India have written to the Minister of Environment Forest and Climate Change, urging implementation of new norms for emission standards and water use of the coal fired thermal power plants.

Deadly ozone has raised its ugly head in Delhi and NCR and without a time bound implementation strategy and preventive action this can deepen into a serious public health crisis. Already dealing with the high particulate matters in the air, the national capital this summer has witnessed an alarming build-up …
Already dealing with the high particulate matters in the air, the national capital this summer has witnessed an alarming build-up of ozone, a Centre for Science and Environment (CSE) study said on Saturday. According to the CSE findings, on several occasions and several locations, between February and May 2017, the …
The study was carried out during the months of April-May, 2017 to assess the status of air quality by monitoring and assessment of some selected air pollutants namely Respirable Suspended Particulate Matter (RSPM or PM10), Fine particles (PM2.5), Sulphur Dioxide (SO2), Oxides of Nitrogen (NOx) and trace metals-Lead (Pb) and …
PARIS: "Excess" diesel truck and car emissions claimed about 38,000 lives worldwide in 2015, said a study Monday that sought to quantify deaths due to pollution that carmakers sought to hide. Four-fifths of these additional premature deaths due to nitrogen oxide (NOx) pollution occurred in three regions — the European …
