The article discusses a study conducted in India to determine the carbon and water footprints of rice, wheat, and corn cultivation across different regions, highlighting the highest water footprint for rice farming and the highest carbon footprint for rice cultivation in South India.

Accumulation of greenhouse gases (GHGs) in the atmosphere has exposed us to the potential warming and its adverse effects on agriculture. The present study deals with the impact of climate change on winter wheat and maize using the Infocrop model. Simulation studies were performed for different timeperiods using HADCM3 factors at four centres located in three different agroecological zones, with prevalent management practices. The results showed that under changed climate, wheat yield decreased whereas the yield of winter maize increased due to warmer winters and enhanced CO2 compared to baseline. Duration of both the crops has decreased owing to the higher temperatures during the growing period. The increase in yield of winter maize points to the suitability of the region for its cultivation in future. Further, increase in maize cultivation in locations with poor wheat yield could well be considered as an adaptation option. [ABSTRACT FROM AUTHOR]
