Crop Modelling for Climate Change Studies

Global climate change is likely to affect world’s food production and poses a serious threat to the agricultural production system. With the increasing pressure of the growing world population agricultural systems needs to take adaptive measures to cater the need of the increasing food demand. Crop models are major tools available to assess the impacts of climate change on the agricultural production system and formulate adaptation measures for the same. This chapter covers the recent trends in greenhouse gases, rainfall, temperature, sea level and extreme weather events. The associated impacts of these changes on food crops were also explained briefly. We also discussed the basics of crop models in brief followed by their applications in climate change study including adaptation strategies. At last, we discussed the key limitations, challenges and uncertainties in the use of crop models in the agricultural production system.
