We estimate the potential reductions in methane and carbon dioxide emissions from several livestock and pasture management options in the mixed and rangeland-based production systems in the tropics. The impacts of adoption of improved pastures, intensifying ruminant diets, changes in land-use practices, and changing breeds of large ruminants on the …
China has tremendous climatic and ecological diversity, so the impacts of climate change on natural and managed systems might likewise be expected to be diverse. Yet so far systematic studies have been rare. Here, the impacts of historical and future climate change on water resources and agriculture in China are …
THE Great Indian Desert, Thar, is expanding, swallowing and degrading about 12,000 hectares of productive land every year. An alarmed Rajasthan government recently asked the state pollution control board to suggest how to arrest the land degradation and soil erosion. The board reviewed about 200 research papers on the impact …
BLACK carbon, or soot, was known as a threat to only the public health until 2007 when the UN climate agency, IPCC, said it is a major contributor to global warming after CO2. The fine particulate matter, which efficiently absorbs sunlight and causes atmospheric warming, is released in large amounts …
Cloudbursts are usually triggered by mountain formations that lead to lifting of moisture-laden winds and forming of a convective cloud. Cloudbursts are common in the western Himalaya. Western disturbances over the Leh region on August 5 might have also triggered the cloudburst, said M Rajeevan, of National Atmospheric Research Laboratory, …
Humans have reduced the abundance of many large marine vertebrates, including whales, large fish, and sharks, to only a small percentage of their pre-exploitation levels. Industrial fishing and whaling also tended to preferentially harvest the largest species and largest individuals within a population. We consider the consequences of removing these …
Geoengineering has been proposed as a feasible way of mitigating anthropogenic climate change, especially increasing global temperatures in the 21st century. The two main geoengineering options are limiting incoming solar radiation, or modifying the carbon cycle. Here we examine the impact of five geoengineering approaches on sea level; SO2 aerosol …
The draft action plan on climate change by Union Territory of Puducherry. It highlights various approaches and activities formulated for adopting six missions under NAPCC to mitigate the climate impacts.

Promoters of nuclear plants need patience and deep pockets. That’s the lesson being reinforced for India—from a showpiece project in its backyard and another in Finland, where French company Areva’s flagship project, is running into time and cost overruns. Both have implications for India’s programme of taking nuclear generation capacity …
HOW do small fish survive predators lurking in the deep ocean? Nature has its way of cautioning them. Species of fish, like mackerel, clownfish and damselfish, have a heightened sense of smell to detect threats and find shelter. Not for long though. Scientists from James Cook University in Australia said …
SEA level is rising, but only in parts of oceans. US researchers have said certain countries across the Indian Ocean, including Bangladesh, Sri Lanka and Indonesia, and Bay of Bengal would see higher than the average sea level rise predicted by UN’s Intergovernmental Panel on Climate Change. On the contrary, …
Why is the river so notorious? Assam has lost about 170,000 hectares to the Brahmaputra and its major tributaries between 1990 and 2007. These are mostly prime land such as tea gardens and the economic loss is phenomenal. The problem is the Brahmaputra transports heavy sediment load—about 800 million tonnes …
Pune Leh cloudburst was an impact of global warming, feel scientists at the Indian Institute of Tropical Meteorology (IITM), Pune. They said extreme events have been increasing in monsoon season due to warming.
Siddharth Kelkar Was the Leh cloudburst a result of the global warming? Scientists at Indian Institute of Tropical Meteorology (IITM), Pune, think it was.
The Public Consultations Report on Green India Mission, one of the eight missions under National Action Plan on Climate Change. It has been prepared by Centre for Environment Education (CEE) for the Ministry of Environment and Forests (MoEF) On May 24, 2010, the Ministry of Environment & Forests released a …
