Abstract
Almost 800 million people lack access to basic water supply, and almost 2000 million lack access to sanitation. Therefore, achieving universal access remains a crucial goal of the global development agenda. In order to shed light on whether international aid might help accomplish that goal, this study evaluates its impact in a sample of 121 developing countries during 1990–2015. A new approach is adopted in which aid affects access not only through provision of infrastructure (supply) but also through health education (demand). Additionally, the long-held concern about the persistence of impacts over time is addressed by estimating panel vector autoregressive models (PVAR). The results show that both supply- and demand-side interventions financed by aid can contribute to promoting access to water, but consistent long-term investments are needed.
期刊介绍：
Water Resources and Economics is one of a series of specialist titles launched by the highly-regarded Water Research. For the purpose of sustainable water resources management, understanding the multiple connections and feedback mechanisms between water resources and the economy is crucial. Water Resources and Economics addresses the financial and economic dimensions associated with water resources use and governance, across different economic sectors like agriculture, energy, industry, shipping, recreation and urban and rural water supply, at local, regional and transboundary scale.
Topics of interest include (but are not restricted to) the economics of:
Aquatic ecosystem services-
Blue economy-
Climate change and flood risk management-
Climate smart agriculture-
Coastal management-
Droughts and water scarcity-
Environmental flows-
Eutrophication-
Food, water, energy nexus-
Groundwater management-
Hydropower generation-
Hydrological risks and uncertainties-
Marine resources-
Nature-based solutions-
Resource recovery-
River restoration-
Storm water harvesting-
Transboundary water allocation-
Urban water management-
Wastewater treatment-
Watershed management-
Water health risks-
Water pollution-
Water quality management-
Water security-
Water stress-
Water technology innovation.
