Background/Question/Methods

Multinational development banks and national governments have begun to appreciate the value of investing in watershed protection for the delivery of water to cities and the reduction of flood risk, but they have lacked tools for evaluating the potential return on investment of natural infrastructure. This talk presents an analysis done to inform the Latin American Conservation Council, which serves to prioritize investment in “water funds” in Latin America.

Results/Conclusions

We briefly discuss the results of a continental assessment that ranks the 70 largest cities in Latin America based on the potential for natural infrastructure to mitigate water quality, stormwater, and riverine flood risks. We then focus the majority of the talk on how we tailored the assessment to the needs of decision makers in Latin America, and how our city rankings were used by decision makers.
