Crop models for assessing impact and adaptation options under climate change

Increased amount of green house gases (GHG) in the atmosphere will cause climate change that adversely impact crop production especially arid and semi-arid regions developing countries. Development implementation field level adaptations measures to cope up with are necessary farmers whose livelihood depends on crop-based income. Crop simulation models incorporate soil-crop-climate processes plant growth sensitive factors can be used quantify evaluating prioritizing adaptation at farm level. This paper analyses impacts plausible agronomic, land water management genetic options for major crops tropical region examples from selected sites India other The need linked improved pest, disease weed analyze predict yield losses, those due change. also extreme weather events is projected increase
