3 September 2012 MURUMA, India – Vilas Dinkar Mukane lives halfway around the world from the corn farmers of Iowa, but the Indian sharecropper is at risk of losing his livelihood for the same reason: not enough rain. With the nourishing downpours of the annual monsoon season down an average of 12 percent across India and much more in some regions, farmers in this village about 250 miles east of Mumbai are on the brink of disaster. “If this situation continues, I’ll lose everything,” said Mr. Mukane, whose soybean, sugarcane and cotton crops were visibly stunted and wilting in his fields recently. “Nothing can happen without water.” Drought has devastated crops around the world this year, including corn and soybeans in the United States, wheat in Russia and Australia and soybeans in Brazil and Argentina. This has contributed to a 6 percent rise in global food prices from June to July, according to United Nations data. India is experiencing its fourth drought in a dozen years, raising concerns about the reliability of the country’s primary source of fresh water, the monsoon rains that typically fall from June to October. Some scientists warn that such calamities are part of a trend that is likely to intensify in the coming decades because of climate changes caused by the human release of greenhouse gases. A paper published last month blamed global warming for a large increase in the percentage of the planet affected by extreme summer heat in the last several decades. And the World Meteorological Organization, a division of the United Nations, recently warned that climate change was “projected to increase the frequency, intensity and duration of droughts, with impacts on many sectors, in particular food, water and energy.” Scientists say that in addition to increasing temperatures, climate change appears to be making India and its neighbors Pakistan, Sri Lanka and Bangladesh more vulnerable to erratic monsoons. Studies using 130 years of data show big changes in rainfall in recent decades, said B. N. Goswami, director of the Indian Institute of Tropical Meteorology, a government-backed research organization. Climate models suggest that while overall rainfall should increase in the coming decades, the region can expect longer dry spells and more intense downpours — forces that would seem to cancel each other out but in fact pose new threats. “Heavy rains are normally short duration, and therefore the water runs off,” said Dr. Goswami, who added that more research was needed to fully understand the impact of climate change on monsoons. “Weak rains are important for recharging groundwater.” India is more vulnerable to disruption from drought than countries like the United States. While agriculture accounts for just 15 percent of India’s economy, half of its 1.2 billion people work on farms, and many of its poorest citizens already cannot afford enough food after price increases of 10 percent or more in the last couple of years. “These kinds of rainfall failures have a lot of human effects,” said Yoginder K. Alagh, chairman of the Institute of Rural Management and a former Indian minister. “A large number of people don’t get employment. There are acute drinking water problems.” Food grain and oilseed production in India could fall up to 12 percent this year as a result of poor rain, said P. K. Joshi, director for South Asia at the International Food Policy Research Institute. […]
