Although global food production has substantially increased in the past few decades, the Millennium Development Goal that aims to halve the proportion of people who suffer from hunger between 1990 and 2015 appears to be beyond reach. Nearly 870 million people still live in hunger today, most of them in South Asia and sub-Saharan Africa. These highly-populated regions with widespread poverty, have large areas under low agricultural productivity. They are prone to high climatic stresses which further compound the problem. These are regions which have been identified as climate change ‘hotspots’.
