Climate change poses many threats to the achievement of the Global Goal on Water and Sanitation – droughts, floods, cyclones, heat waves and rising sea levels all impact on the water cycle and the sustainability of WASH services. Fortunately, developed countries have committed to a goal of jointly mobilising US$100 billion a year by 2020 to help poor countries both mitigate and adapt to climate change. This presents a unique opportunity to drive, at least in part, a paradigm shift in WASH sector development. WaterAid research, alongside interviews with the major global climate funds, has shown that the water sector has not been as effective as have other sectors in building a case for why climate-resilient WASH is a valid adaptation mechanism, what exactly this looks like, and how adaptation financing could be effectively spent. As such, WaterAid is leading a new Climate Finance Initiative with the overarching objective of building collaborative partnerships in several countries to demonstrate, through project execution and associated institutional strengthening, the changes that are needed to ensure that a proportion of future climate finance flows is spent on increasing the water security and climate resilience of people living in WASH poverty. The next step in the Initiative requires in-depth research of the global climate finance architecture in addition to an analysis of the sector blockages in a number of case study countries that will then be used as demonstration sites. Research questions include: What are the contextual, institutional and political factors that can help to secure global climate finance for WASH? What specific changes are required at national and sub-national levels to ensure climate finance is accessed to develop, and ultimately provide a proportion of funds to, a climate-resilient water sector strategy or climate-resilient WASH projects? WaterAid is requesting short proposals (2000-3000 words) by 16 November 2015. Read more information in the request for proposal.
