Résumé:
Ce rapport présente les conclusions d’une recherche axée sur les risques posés par le changement climatique sur la délivrance des services d’eau, d’assainissement et d’hygiène en Afrique. Il s’appuie sur une revue de différents cas d’étude au Malawi, en Sierra Leone et en Tanzanie. Un document d’étude complémentaire fournit les données et résultats détaillés des projets cités. Abstract:
This report presents the findings of research into the risks to delivery of WASH results posed by climate change in Africa, drawing on rapid case study reviews of WASH programming in Malawi, Sierra Leone and Tanzania. A separate Case Study Report provides further detail on country background and findings.
Given the uncertainties with rainfall projections, but also the known risks associated with existing variability, there are strong arguments for a vulnerability rather than an impact-led approach to risk assessment and planning. This implies a stronger focus on ensuring the reliability and protection of drinking water sources and simple changes to latrine design to reduce the risks of flooding under current climate variability as a first step towards adaptation through relatively low cost changes in design or practice.
