Extractions: There is a broad consensus that tropical areas are slated to see an expansion of arid zones. This will be accompanied by a contraction of 31-51 million ha of favourable cultivation areas and a significant reduction in food production in the most vulnerable areas where population density is high and food already scarce. Nearly one billion affected people live in these vulnerable environments, dependent on agriculture. These vulnerable populations have limited capacity to protect themselves from the environmental hazards that will accompany climate change, like drought and floods, and will suffer most from land degradation and biodiversity loss. According to estimates, a little less than half the production potential in certain developing countries could be lost. In South Asia, the biggest blow to food production is expected to come from the loss of multiple cropping zones. The worst affected areas are predicted to be the double and triple cropping areas like Punjab, Haryana, western Uttar Pradesh from where the surplus grain for our buffer stock comes. This means areas where two to three crops are produced in a year and which are predicted to turn into single crop zones, where only one crop can be taken in a year because the rest of the season will be too hot and dry for cultivation. For South Asia, particularly India, one of the most serious impacts is anticipated in wheat production. Wheat is the single largest winter crop of north India and states like Punjab, Haryana, Western Uttar Pradesh produce the surplus wheat that goes into the PDS. Wheat is a particularly temperature sensitive crop and it has been estimated that for every one degree rise in temperature, wheat producing areas in India and South Asia will lose about four to five million tonnes of production. This will have a cascading effect on food for the poor.
