With drought looming, Sri Lanka tries something new
With rainfall in many areas just a third of that last year and many water reservoirs far below normal levels, Sri Lankans have begun holding traditional ceremonies to invoke rain - some with the participation of President Maithripala Sirisena. But this time, national officials are also doing something new to prepare for what many fear could be the worst drought in decades: Developing plans, in advance, to deal with it.
Those include everything from allowing communities to take only drinking water from drying reservoirs to removing taxes on imported rice and looking for alternatives to hydropower to maintain the national electric grid. “The change came about because we were able to predict the onset of the drought well in advance and with detailed information,” said Lalith Chandrapala, the head of Sri Lanka’s Meteorological Department. The country has had clear signs since last October that drought was coming, officials say.
During 2016, Sri Lanka had only one period of exceptionally high rainfall, with some areas receiving over 300 mm of rain in three days, leading to flooding and landslides. Apart from that, rain was less than normal almost all year. “We have a rainfall deficit and it is likely to stay that way until the next monsoon” in June and July, Chandrapala said. According to the Meteorological Department, in some districts rainfall has been 30 to 40 percent of normal levels. Some of these districts are also among the country’s largest agriculture producers.
Less rice, less power
The lack of rainfall severely affected paddy rice production in the last growing season. According to the Disaster Management Center (DMC) only around 300,000 hectares out of a possible 800,000 were cultivated, largely because of a lack of irrigation water. Reservoirs that will provide water for the next growing season, which starts in March, need to be at least half filled by that time to support a normal harvest. But DMC officials and Chandrapala said the country’s main reservoirs were currently less than a third full.
“It nothing like I have ever seen before,” said Ranjith Punyawardena, an agro-climatologist at the Department of Agriculture. The lack of water is likely both to hurt agriculture and cut into supplies of vital hydropower. Already, as a result of drought, the country is getting 80 percent of its electricity from coal and oil and only 11 percent from hydropower. Normally, at this time of year, the country would get at least 40 percent of its electricity from hydropower, according to the electricity board. — Reuters
