Feasibility and Effectiveness Assessment of Multi-Sectoral Climate Change Adaptation for Food Security and Nutrition

Purpose of Review This review aims to identify the evidence for the assessment of the effectiveness and feasibility of multi-sectoral climate adaptation for food security and malnutrition. This review and the assessments of the evidence inform the contents and confidence statements in section “multi-sectoral adaptation for malnutrition” and in the Executive Summary of the IPCC AR6 WGII Chapter 7: Health Wellbeing and Changing Community Structure. Recent Findings A review of adaptation for food security and nutrition FSN in West Africa concluded that food security and nutrition and climate adaptation are not independent goals, but often go under different sectors. Summary Most of the adaptation categories identified here are highly effective in reducing climate risks to food security and malnutrition, and the implementation is moderately or highly feasible. Categories include improved access to (1) sustainable, affordable, and healthy diets from climate-resilient, nutrition-sensitive agroecological food systems; (ii) health care (including child, maternal, and reproductive), nutrition services, water and sanitation; (iii) anticipatory actions, adoption of the IPC classification, EW-EA systems; and (iv) nutrition-sensitive adaptive social protection. Risk reduction, such as weather-related insurance, and risk management are moderately effective and feasible due to economic and institutional barriers. Women and girls’ empowerment, enhanced education, rights-based approaches, and peace building are highly relevant enablers for implementation of the adaptation options.
