In response to Sudan’s challenges stemming from climate change, conflict and fragility, the UN Environment Programme (UNEP) and the European Union launched phase two of the Wadi El Ku Catchment Management Project (WEK 2). The first phase of the project (WEK 1) aimed not only to enhance agricultural production and mitigate the impacts of drought in North Darfur, but also to resolve natural resource conflicts, bolster stability, and provide valuable lessons for sustainable environmental management, conflict resolution and community resilience. Building on the successes of WEK 1, this second phase of the project (WEK 2) stands as a testament to collaborative efforts to address the far-reaching consequences of climate change and conflicts over natural resources. WEK 2 linked climate change adaptation, natural resource management, peacebuilding and livelihood approaches. By leveraging water as a tool for peace and increasing agricultural productivity, WEK 2 exemplifies a strategic response to the development of and security challenges posed by a changing climate.
