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 …
The negative effect of increasing atmospheric nitrogen (N) pollution on grassland biodiversity is now incontrovertible. However, the recent introduction of cleaner technologies in the UK has led to reductions in the emissions of nitrogen oxides, with concomitant decreases in N deposition. The degree to which grassland biodiversity can be expected …

Biochar, a carbon-rich, porous pyrolysis product of organic residues may positively affect plant yield and can, owing to its inherent stability, promote soil carbon sequestration when amended to agricultural soils. Another possible effect of biochar is the reduction in emissions of nitrous oxide (N2O). A number of laboratory incubations have …
From 2017, thermal power plants across India will have to cut particulate matter emissions by as much as 40 per cent and reduce their water consumption by nearly a third according to this notification by the Union Ministry Of Environment, Forests and Climate Change. The Ministry of Environment, Forest & …
While high levels of pollution due to increasing number of vehicles is one problem, poor Pollution under Control (PUC) test centres worsen the air. In a workshop organised by the Centre for Science and Environment (CSE) on 'Urban air quality challenge and strategies to reduce emissions from in use and …
New Delhi: Taking a serious note of the recent Volkswagen emissions scandal, experts on Monday said India is also vulnerable to such fraud due to its weak emission regulations. In a workshop titled, "Urban air quality challenges and strategies to reduce emissions from in-use and new vehicles" organized by the …
When it’s protecting us from harmful ultraviolet rays of the sun at higher altitudes, ozone is great. But at ground-level, the gas is classified as an air pollutant that poses serious health risks, and its increase in Delhi has experts alarmed. Ozone is not found naturally at ground-level; it is …
The observation of high aerosol hygroscopic growth in Madrid is mainly limited to specific atmospheric conditions, such as local stagnation episodes, which take place in winter time. One of these episodes was identified in December 2014 and the hygroscopic growth factor (GF) measurements obtained in such episode were analysed in …
The US Environmental Protection Agency (EPA) has alleged that Volkswagen Group of America (VW) violated the Clean Air Act (CAA) by developing and installing emissions control system 'defeat devices' (software) in model year 2009–2015 vehicles with 2.0 litre diesel engines. VW has admitted the inclusion of defeat devices. On-road emissions …
The Delhi government is planning to make public real-time air pollution levels in various parts of the city this winter. While real-time data is already available on the Delhi Pollution Control Committee's website, it's now working on placing information boards at crowded places and areas prone to snarls. The idea …
Europe’s biggest countries are lobbying for a proposed EU cap on nitrogen oxide (NOx) pollution from cars to be weakened in a vote on Wednesday, despite the VW diesel emissions scandal and revelations that 90% of cars do not currently meet pollution standards when on the road. The UK has …
Revelations that Volkswagen, the world’s biggest car maker, rigged its emissions testing in the United States to circumvent regulations and boost its sales have sent shock waves through the car industry. On 22 September, the company admitted that it had used special software to lower emissions during laboratory tests of …
Satellite remote sensing of tropospheric nitrogen dioxide (NO2) can provide valuable information for estimating surface nitrogen oxides (NOx) emissions. Using an exponentially modified Gaussian (EMG) method and taking into account the effect of wind on observed NO2 distributions, we estimate 3-year moving-average emissions of summertime NOx from 35 US (United …
Low nitrogen availability in the high Arctic represents a major constraint for plant growth, which limits the tundra capacity for carbon retention and determines tundra vegetation types. The limited terrestrial nitrogen (N) pool in the tundra is augmented significantly by nesting seabirds, such as the planktivorous Little Auk (Alle alle). …
Directly aping Euro norms might be a problem considering the driving conditions peculiar to India that might require the adaptation of critical components to work in these conditions. Even as Minister for Road Transport & Highways (MoRTH) Nitin Gadkari has urged automobile manufacturers to leapfrog from Bharat Stage-IV emissions norms …
China's emissions of two key pollutants fell slightly in the first half of 2015, according to the environment ministry, as authorities stepped up punitive measures to combat environmental degradation. Emitted levels of sulfur dioxide and nitrogen oxide - both associated with acid rain - were down 4.6 percent and 8.8 …
China’s Ministry of Environmental Protection revealed Sunday that the country’s major polluting emissions declined in the first half of 2015. Published on the Ministry of Environmental Protection’s website and sourced through China’s state news agency, Xinhua, the statistics reveal that China’s major polluting emissions “have been on a large-scale decline …
SALT LAKE CITY (AP) - Utah residents buying a new water heater will soon be required to pay more for one that emits less nitrogen oxide due to a new rule designed to reduce wintertime pollution. Joel Karmazyn, an environmental scientist with the Utah Division of Air Quality, said officials …
Analyzes results of emissions tests on 32 Euro 6 diesel passenger cars from 10 different manufacturers. Results show some automakers meeting diesel NOx emissions standards under more realistic driving conditions, while others lag badly. Controlling nitrogen oxide (NOx) emissions from Euro 6 diesel passenger cars is one of the biggest …
Nitrogen fixation rates of the globally distributed, biogeochemically important marine cyanobacterium Trichodesmium increase under high carbon dioxide (CO2) levels in short-term studies due to physiological plasticity. However, its long-term adaptive responses to ongoing anthropogenic CO2 increases are unknown. Here we show that experimental evolution under extended selection at projected future …
