This briefing paper presents findings from Oxfam’s recently commissioned research on climate predictions for 2040 and 2050 in the Middle East, the Horn, East and Central Africa (HECA), West Africa and Asia regions. Analyses show how temperature increases will influence water insecurity in these regions and the potential impacts on food security, the spread of diseases, and other factors. This briefing paper also reveals severe under-investment by national governments and donors in water, sanitation and hygiene (WASH) systems, with critical implications not only for water security but also for poverty and inequality. Oxfam is calling for urgent action to increase investments in sustainable, climate-adapted water management for the people who are most at risk from the worsening climate crisis.
