2025 was one of the driest years for global rivers since the 1980s.

The United Nations Environment Programme (UNEP) highlights how drought devastates households and ecosystems, pushing communities to adopt innovative adaptation measures. In Sri Lanka, ancient tank cascades are being revived to manage water resources more effectively. Meanwhile, in Niger, zai pits—small planting holes filled with compost—are helping farmers cope with scarce rainfall.

These strategies aim to reduce the risk of drought by improving water retention and distribution, ensuring that communities can better withstand dry periods.

The long-term vulnerability remains high as climate change intensifies drought conditions. Ecosystems face degradation due to prolonged water stress, threatening biodiversity and agricultural productivity.

What is the long-term climate outlook for this region?

Communities must continue adapting with local solutions like tank cascades and zai pits to build resilience against future droughts. However, these measures alone may not be enough as global warming exacerbates water scarcity issues.

The outlook is challenging without broader climate action.
