Analyzing water poverty in basins

Abstract

Inadequate provision of water-related services in developing countries continues to undermine strategies for poverty alleviation. The root lies in the inability of policy makers to tackle resource development in a holistic and integrated manner. This requires a multi-faceted approach to combine physical estimates of water availability with the socio-economic drivers of poverty. It is with this in mind that the Water Poverty Index (WPI) was created. However, water resources are dynamic, and the linkages between water scarcity and poverty incorporate complex cause-effect relationships. Water poverty should thus be addressed in a more systemic way. This would allow a comprehensive understanding of the crosscutting nature of water issues and impacts. In this paper, a system approach has been adopted to develop a structured framework for a multi-dimensional evaluation of water poverty in basins. It is an attempt to assess the diverse, interacting components of catchment processes, societal pressures, and policy actions. An enhanced Water Poverty Index (eWPI) has been developed and is proposed in this study. To exemplify the utilisation of the index, and to test its applicability and validity, eWPI has been piloted in a Peruvian watershed as initial case study. Results highlight the likely utility of the tool to identify areas for improvement, and ultimately guide appropriate action towards better service delivery and sustainable management of water resources.
