Monsoon 2019 was a bit humdrum, at first. For some time, it seemed many parts of India wouldn't receive as much rainfall as they typically do. But a sudden change of gear — pouring cats and dogs in a short span — led to deluges and flash floods, even cloud bursts. These district-specific charts based on IWMI/WLE data show how this is happening.
A new urgency is being felt on climate change. Schoolchildren are striking, there are protests in the streets, and politicians across the world, including the UK, are pushing to call climate change a national emergency. In some regions, heat and pests will not be the most significant climate threat – flooding will. The International Water Management Institute is therefore trialling several options to keep farmers’ yields and profits safe from the storms.
In the mountainous areas of Nepal, springs are the primary source of water for remote communities, serving as a mainstay of rural livelihoods. Springs are especially critical for dry-season agriculture because they can provide access to water stored in groundwater aquifers. The discharge from springs is declining, however, possibly as a result of population growth and changes in land use (including agricultural expansion and deforestation) and the climate. Recharging and sustaining groundwater aquifers is key for ensuring year-round water availability in connected springs and for reducing the reliance of upland communities on rainfall.

IWMI researchers are using environmental isotopes analysis, hydro-meteorological and hydrogeological measurements to identify the dominant recharge zones for springs.
Much of the developing world, including Sri Lanka, is facing an organic waste challenge, but the right economic incentives and business models can help turn waste into food and energy, WLE/IWMI told a recent business forum in Colombo.
Following the successful debut of index-based flood insurance (IBFI) in India’s Bihar State during 2017, the International Water Management Institute (IWMI) and its partners have continued their search for ways to make this tool more effective in helping farm families manage disaster risk. Bihar is the country’s most flood-prone state, with about 40 million hectares subject to periodic flooding.
Colombo is one of the first 18 cities that has been accredited as a Ramsar Wetland City at the 13th meeting of the Conference of the Parties to the Convention (COP13) held in Dubai, United Arab Emirates on October 25, 2018.
