New Delhi : How does a warming environment affect rainfall, cropping patterns, livelihoods? What could be the alternatives that people whose livelihoods are hit by the effects of climate change do to cope? An initiative by Britain and Canada seeks to study and tackle the effects of climate change in South Asia, in tandem with TERI and Jadavpur University in India and similar institutes in neighbouring Pakistan and Bangladesh.
Canada’s International Development Research Centre (IDRC) and the UK’s Department for International Development (DFID) have launched a research programme to “take a fresh approach to understanding climate change and find ways to adapt” in some of the hot spots.
The programme, named Collaborative Adaptation Research Initiative in Africa and Asia (CARIAA), a seven-year Canadian dollar 70 million research initiative, seeks to study the effects of climate change in three hot spots — semi-arid regions, river deltas and Himalayan river basins.
K.S. Murali, senior programme officer with IDRC, told IANS: “We try to understand what are the different scenarios that can happen with one degree rise in temperature, with a two-degree rise in temperature.”
In semi-arid regions, for example in Madhya Pradesh, where there is relatively high temperature and the rainfall hovers between 300-700 mm a year, rise in temperature can badly hit cropping patterns, said the researcher.
Semi-arid areas are dominated generally by dry land and agriculture is rain fed, or dependent on rainfall. “If the rain becomes erratic, or the area receives less rain, or it is not distributed equally, the cropping pattern is affected badly and cultivation is hit. Not just the summer temperature, the winter temperature too gets affected, and there is high rate of evaporation,” he said.
The effects of climate change on river deltas, where the river meets the sea, and coastal estuaries are also to be studied. This includes the Sundarbans mangrove forest shared between India and Bangladesh.Climate change would also affect the Himalayan river.
