Impact, Mitigation, Adaptation, and Food Security for Promotion of Sustainable Agriculture Through Green Technology

Over the past few decades, the man-induced changes in the climate of the earth have become the focus of scientific and social attention. The most imminent of these is the increased levels of greenhouse gases (GHGs) such as carbon dioxide, methane, and nitrous oxide in the atmosphere leading to global warming. The recent report of the Intergovernmental Panel on Climate Change (IPCC) has reconfirmed the increasingly strong evidence of global climate change and projected that the global average temperature of the air above the earth's surface would rise by 1.8-6.4oC by the end of the century depending upon the developmental pathways of the countries. For the Indian region (South Asia), the IPCC has projected 0.5-1.2oC rise in temperature by 2020, 0.88-3.16oC by 2050, and 1.56-5.4 oC by 2080, depending on the scenario of future development. Overall, the temperature increase is likely to be much higher in winter (rabi) than in the rainy (kharif) season. Precipitation is likely to increase by 15-40% by the end of the century.
