At a time when climate change is set to impact rice production in Asia, simple water management by farmers as an adaptation strategy will minimise the damage, an expert said.
“Climate change will impact rice production in large parts of Asia, including India. Water management will be a key feature of decisions aimed at adapting to the impacts of climate change,” Dennis Wichelns, Senior Research Fellow of Thailand-based Stockholm Environment Institute (SEI), said during the Knowledge Forum on Climate Resilient Development in Himalayan and Downstream Regions.
The event was organised jointly by the Ministry of Agriculture and Farmers Welfare, Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD) and Delhi-based IEG.
According to Wichelns, improvement in water management will help in areas where higher temperatures are likely and where shift in rainfall pattern is expected.
In certain areas, crop yields will increase in some seasons, perhaps in response to higher rainfall during the production cycle or with a reduction in summer days in the northern regions. In other areas, yields might be reduced due to higher night temperatures, untimely drought conditions, or submergence caused by massive natural events.
According to Wichelns, improvement in water management will also help in reducing methane emissions and arsenic uptake in the rice fields.
