Climate change has altered not only the overall magnitude of rainfall but also its seasonal distribution and interannual variability worldwide. Such changes in the rainfall regimes will be most keenly felt in arid and semiarid regions, where water availability and timing are key factors controlling biogeochemical cycles5, primary productivity, and the phenology of growth and reproduction, while also regulating agricultural production.

Tropical rainforest regions have large hydropower generation potential that figures prominently in many nations’ energy growth strategies. Feasibility studies of hydropower plants typically ignore the effect of future deforestation or assume that deforestation will have a positive effect on river discharge and energy generation resulting from declines in evapotranspiration (ET) associated with forest conversion. Forest loss can also reduce river discharge, however, by inhibiting rainfall.

The habitats of many common plants and animals will shrink dramatically this century unless governments act quickly to cut rising greenhouse gas emissions, scientists said on Sunday after studying

Works taken up as part of NREGA scheme were found to help maintain ground water levels, aiding crop productivity

The UPA government’s flagship employment guarantee programme can play an important role in conserving natural resources and sustaining water supply and food production, according to a study. Conceived to provide livelihood security for the rural poor, the scheme can also help reduce and counter the impact of climate change in villages, according to the study, “Environmental Benefits and Vulnerability Reduction through Mahatma Gandhi National Rural Employment Guarantee Scheme” by IISc, Bangalore in collaboration with the rural development ministry and the German international co-operation agency, GIZ.

Maharashtra is facing one of the worst droughts this year. Union Agriculture Minister Sharad Pawar as well as Chief Minister Prithviraj Chavan have said that this year’s drought is worse drought than the one in 1972, which was termed as a ‘famine’.

Global warming will increase the intensity of extreme rainfall events leading to more flooding in future, new research has predicted.

Blame it on climate change as Uttar Pradesh is witnessing a shift from the traditional variety of foodgrains to hybrid ones as there is a sharp decline in production of conventional varieties of wh

Proxy indicators of relative moisture balance, in combination with long control simulations from coupled climate models, show that the Indian Ocean drives multidecadal hydroclimate variability by altering the local Walker circulation, whereas the influence of the Pacific Ocean is minimal on these timescales.

Black carbon, the soot produced by burning fossil fuels and biomass, is a more potent atmospheric pollutant than previously thought, according to a four-year international study released on Tuesday

Black carbon is the second most powerful climate pollutant behind only carbon dioxide, according to a landmark four-year assessment lead by T.C. Bond, S. J. Doherty, D. W. Fahey, and P.
