Climate change affects both water resources and nutrition profoundly, putting pressure on achieving key human wellbeing goals. Measures to address adverse climate-induced nutrition and water impacts, such as reduced agricultural productivity, malnutrition and illness, can, in turn, affect and even accelerate climate change. While evidence on the interlinkages between climate change -water - and nutrition is only emerging, key development actors and investors are requesting support today to implement nutrition-sensitive, climate-smart and water-secure policies. This session will present an overview of climate-water-nutrition interactions as well as a series of interventions to strengthen nutrition outcomes through water interventions and to strengthen water security through changes in diets and nutrition, which are becoming more important as a result of climate change. We will also hear from individuals on the ground what they are doing to improve nutrition and health through better irrigation design and management.
