Saved health/Saved wealth

An approach to quantify adaptation benefits in terms of avoided economic damages, illnesses and mortality

Description

Saved Health/Saved Wealth is an approach to quantify the benefits of adaptation measures in terms of avoided economic damages, illnesses and mortality. It can be used a priori based on scenarios to select the most promising adaptation options, or as an evaluation tool for ongoing or completed adaptation projects. Its methodology compares a baseline situation (economic assets and life expectancy) with economic and health losses that have been avoided through adaptation. The calculation requires data on possible health impacts (Disability-Adjusted Live Years: DALY) and/or economic impacts as well as assumptions about the counterfactual (what would have happened without adaptation). To limit complexity, the approach is typically applied to a single climate change impact such as flooding. A pilot application has been undertaken for a coastal protection project in Viet Nam. The methodology is described in detail in the publication and illustrated by comparing two adaptation options in Viet Nam: building a dyke or planting mangroves. An excel tool is provided for calculation of Saved Health and Saved Wealth.

A special feature of the Saved Health / Saved Wealth approach is that it can also be used to estimate adaptation benefits before a project starts based on scenarios of climate change impacts.
