A substantial proportion of the population of the Indian sub-continent depends on cool season grain legumes (in particular, dry pea, chickpea and lentil) as a major component of their diet. From 2001 to 2007, India was the main producer of the major cool season grain legume crops, followed by Canada, China, France and Russia. Although India was the main producer of cool season grain legumes from 2001 to 2007, it was also the main importing country of these crops over the same period, followed by Spain, Egypt, Bangladesh, Belgium, the Netherlands and Pakistan. The main exporter of cool season grain legume crops from 2001 to 2006 was Canada, followed by Australia, France, the USA and Turkey. An important feature of the data is that the major exporting countries are developed countries, while major importers are India, Bangladesh and Pakistan, the three largest countries with respect to population in the Indian sub-continent. Climate change models predict increasing temperatures, decreasing rainfall and hence decreased yields of cool season grain legume crops in substantial areas of the Indian sub-continent over the next fifty years. If these predictions prove to be correct, and demand is augmented further due to rapidly growing populations, then it is likely that the Indian sub-continent will need to rely more heavily on imports of grain legumes. In relation to the current major export countries, climate change models predict increases in yields in Canada, USA and France but decreased yields in Australia and Turkey. Because of this, and because Canada, USA and France have an established infrastructure favourable to increases/ shifts in production of cool season grain legumes, they are the countries most likely to be able to respond to increased demand. In conclusion, if climate change results in decreased productivity of cool season grain legume crops in the Indian sub-continent, then Canada, France and the USA are likely to be the countries that would meet the increased demand for these crops.
