The water purification functions of forests represent one of the most frequently invoked examples of non-market ecosystem services that are economically valuable. Yet, there has been a paucity of statistical estimates that robustly quantify such benefits. This study enriches this thin evidence base through valuing forests’ water purification services in the form of the ensuing cost savings of municipal drinking water treatment, using a rich panel dataset from China’s Sichuan province.

Distributional Statistics of Municipal Water Use During Cape Town’s Drought: Implications for Affordability, Conservation and Tariff Design 20-23

Submitted by Eugenia Leon on 7 July 2020

We calculate the first distributional statistics for municipal water supply deliveries using 14.9 million monthly billing records for a half-million households in Cape Town, South Africa, from 2014-2018. These years span a historic drought and a multi-faceted package of conservation programs that achieved a 50% city-wide drop in consumption. We find that the top 10% of households consumed 31% of water deliveries before the drought, with the Gini coefficient
