2. Impact of Climate On Major Crops

The UN Panel on Climate Change is informing the world on what damage global warming can cause. But a recent study shows how temperature changes have already hit the global economy and Indian agriculture is suffering the brunt of it. The study proves that agriculture losses worth US$5 billion annually from 1981-2002 can be correlated to temperature rises over the period. The study published in 'Environmental Research Letters', a journal published from the UK, has shown that almost 30% of the variation in global agricultural yields can be explained by rise in temperature.[1]

Climate change and an increasing population could trigger a global food crisis in the next half century as countries struggle for fertile land to grow crops and rear animals, scientists warned on Thursday. To keep up with the growth in human population, more food will have to be produced worldwide over the next 50 years than has been during the past 10,000 years combined, the experts said.[2]
