Résumé:
Ce rapport présente les liens entre changement climatique et eau, en s’appuyant sur la littérature scientifique et la littérature grise pour un public informé mais non expert. Commandé par WaterAid UK, ce rapport a deux principaux objectifs :
- faire une synthèse des prévisions et scénarii des impacts du changement climatique sur les ressources en eau et la délivrance des services d’eau, d’assainissement et d’hygiène en Afrique sub-saharienne et en Asie du Sud
- envisager ces implications à différents niveaux, de l’investissement international à la planification et mise en œuvre d’interventions au niveau des communautés.
Abstract:
Water is predicted to be the primary medium through which early climate change impacts will be felt by people, ecosystems and economies. Both observational records and climate projections provide strong evidence that freshwater resources are vulnerable, and have the potential to be strongly impacted. However, impacts on water resources and water-dependent services have yet to be adequately addressed in either scientific analyses or water policy.
This report aims to fill in some of the gaps. No new research is presented; rather the aim is to pull together what we know about the links between climate change and water, drawing on both the scientific and non-scientific literature, for an informed but non-specialist audience. Commissioned by WaterAid in the UK, the report has two broad objectives:
•To summarise current understanding of climate change projections and scenarios, and the impacts climate change may have on water resources, and water supply, sanitation and hygiene (WASH) in Sub-Saharan Africa (SSA) and South Asia.
•To discuss implications of the above for policy and practice at a range of different levels, from funding for climate change adaptation at an international level, to the planning and implementation of WASH interventions at a community level.
