Dar said changes in climate will alter populations and the geographic spread of pests and pathogens, which also need to be countered with more resistant plant varieties. Experts from ICRISAT urged governments and international donor agencies to invest more in crop research in view of the adverse projections on agriculture due to global warming. They said focus should shift to crops such as pearl millets and sorghum that grow in arid and semi-arid tropics. Refocusing research in this way would have implications in training programmes for plant breeders and agricultural education systems, they say. Production of rice, staple food of billions, most of whom live in poor countries, will be the most affected by global warming, as higher temperatures shift the time of pollination and affect grain formation, said Dyno Keatinge, ICRISAT deputy director-general.
Increased frequency of droughts as a result of global warming will reduce crop production, with most of the people vulnerable to hunger being in
