Research: Sustainability and scalability

Introduction

A persistent challenge in the water and sanitation sector is designing service improvements that are both sustainable, i.e., that continue to provide safe, reliable, affordable services over the long-term, and that can achieve impact at large scale quickly. Indeed, in many cases these two objectives can be in conflict. Our group is interested in operationalizing different conceptions of sustainability (e.g., financial, social, environmental), as well as investigating the linkages between user demand (preferences) and sustainability. 

Current projects

Using data from communities in Bolivia, Peru, and Ghana we are investigating the linkages between pre-construction community investments and post-construction financial sustainability of rural water systems.

We are also investigating the contribution that productive uses of water (e.g., for raising livestock, small-scale irrigation, etc.) makes toward sustainability of rural water systems in Kenya, Colombia, and Senegal.
