Climatic changes and increasing climatic variability are likely to aggravate the problem of future food security by exerting pressure on agriculture. However, there are lot of uncertainties about the assessment of impact, adaptation and mitigation of climate change in agriculture. It is largely b...

South Asia perspectives on climate change and agriculture: adaptation options
Global warming is a prominent environmental issue of the twenty-first century. Agriculture contributes to the global warming primarily through the emission and consumption of greenhouse gases (GHGs), viz. methane, nitrous oxide and carbon dioxide. The major sources of emission of GHGs in the agri...

Low carbon technologies for agriculture: a study on rice and wheat production systems in the Indo-Gangetic plains
Increased use of irrigation and nitrogen (N) in rice and wheat would increase productivity. It would also enhance the emission of greenhouse gases from soil causing global warming and climate change. This study quantified the trade-offs between increased production with N fertilizer and irrigatio...

Carbon emission occurs during various stages of life cycle of food products. Greenhouse gases (GHG) emission from 24 Indian food items showed that animal food products (meat and milk) and rice cultivation mostly contributed to methane (CH4) emission, while food products from crops contributed to ...

The Rice-wheat (RW) cropping system is one of the major agricultural production systems in four Indo-Gangetic Plains (IGP) countries: India, Pakistan, Bangladesh and Nepal of South Asia covering about 32% of the total rice area and 42% of the total wheat area. The excessive utilization of natural...

The intensified rice and wheat cropping systems consume most of the fertilizer and irrigation water in India and are major sources of greenhouse gas (GHG) emissions. The InfoCrop simulation model was evaluated to calculate methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) emissions fro...

A low-cost free-air carbon dioxide enrichment (FACE) system has been developed at the Indian Agricultural Research Institute, for assessing the climate change impacts on crops. In the FACE system, the supply and monitoring of CO2 is regulated by the computer-based SCADA system. Carbon dioxide con...
