A Methodology to Identify the Best Cities for Water Funds
The Water Security Working Group will develop and demonstrate a methodology to identify the most promising cities for replicating and scaling up water funds.
The conceptual approach is that the most suitable areas for water fund expansion are where there is the greatest overlap between (i) high risk —
quantified as vulnerability times exposure; and (ii) high opportunity — where biophysical, economic and social characteristics of the region are best suited for natural infrastructure to be effective.
The Working Group will focus on a methodology to compare major and emerging cities across Latin America. In this region, influential decision-makers such as multilateral banks, federal water agencies, and multinational partnerships are positioned to use the deliverables of this project to replicate and scale up investments in water funds over the next 5 to 10 years.
The Working Group will focus on three major components in developing the methodology:
- Source water protection:calculating the potential return-on-investment in biophysical and monetary units for natural infrastructure strategies to mitigate risks and help regulate water supply and water quality to meet urban needs.
- Flood risk mitigation: analyze extent of current and projected future flood risks on people and urban infrastructure and identify watersheds likely to respond to natural infrastructure interventions to reduce flood peaks in rivers before entering urban areas and stormwater systems.
- Institutional enabling conditions:computing indicators summarizing institutional factors that predict the durability of a water fund mechanism, based upon experience from existing funds and other payment for ecosystem services programs.
From these three components, the Working Group will produce a flexible and customizable “dashboard” of information and associated products that will enable key stakeholders to evaluate the strengths and limitations of watershed strategies in major cities throughout Latin America. Stakeholders will also be able to use this information to catalyze water fund expansion where it is most promising and enable replication of the approach to other regions.
