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 higher CO2 on crop growth. Dynamics of pests and diseases will be significantly altered. Agriculture contributes 28% of the Indian greenhouse gases emissions, primarily due to methane emission from rice, enteric fermentation in ruminant animals, and nitrous oxides from application of manures and fertilizers to the soils. Potential approaches to reduce these emissions include mid-season drainage or alternate drying in rice, approaches to increase N-use efficiency and soil carbon, and improvement in livestock diet. Simple adaptation strategies, such as change in planting dates and varieties could help in reducing impacts of climate change to some extent.
