New Delhi: With the international fraternity giving the issue of global warming top priority and involving in a blame game, its first victim may be the platter of the common man.

According to a detailed study conducted by David B Lobell and Adam Sibley of Stanford University and J Ivan Ortiz Monasterio of ‘International Maize and Wheat Improvement Centre’ in the main wheat growing land areas in North India, one degree rise in the temperature can affect the wheat production by about ten percent.

According to the research published in the international magazine ‘Nature’, the impact of rise in temperature on wheat yield has been scarcely calculated. The study revealed that in some cases, a minor rise in temperature of 2 degrees reduced the production of wheat by a whopping 50 percent.

Studying satellite records of nine years, direct effect of rise in temperature was recorded on the production of wheat. Also, the temperature variation had a visible effect on the number and shape of wheat grains. When the temperature increased by 2 degrees some 30 days before the ripening of the crop, it not only reduced the number of wheat grains but a change in the shape of the grains was also observed.

As a result, they concluded that one degree rise in temperature can reduce the crop yield by ten percent.

According to the officials of the Directorate of Wheat Research, “The facts evolved in the study are very significant. It requires us to be attentive on two levels. One, we would have to speed up the global efforts made to control climate change and develop a wheat variety which can bear the increasing temperature.”

There is an urgent need of boosting crop production amid the swelling population and increasing urbanization. The United Nations Food and Agriculture Organisation says, the food production need to be increased by 70 percent around the globe by 2050.
