Phytoplankton are sensitive to changes in river ecosystems. However, the spatial impacts of dams on phytoplankton communities have not been well documented, and the relationships between environmental drivers and phytoplankton communities in different types of river reaches need to be further...

We estimate the effect of large dams on malaria incidence in India between 1975 and 1995. We combine instrumental variables approach with a panel model with unobserved common factors allowing us to fully capture the endogeneity of dam location and unobserved time-varying heterogeneity. Dams...

Traditional interventions for mitigating flood risk and increasing water security continue to focus mainly on large-scale engineering solutions despite a growing body of evidence showing that large-scale water infrastructure investments can incur large cost overruns and produce significant,...

We use satellite, hydrology, and census data from 1990 to 2014 to examine the distributional impacts of dams on cropland productivity and economic development in China. We exploit a county’s river gradient and elevation to deal with the endogeneity of dam location. We find that an additional...

The Klamath River, draining some 12,000 square miles in southern Oregon and northern California, was once the third largest salmon stream on the West Coast, the life force of Native Americans. The river runs 263 miles from headwaters in Oregon and flows through the Cascades to the Pacific Ocean...

The construction of large dams is one of the most costly and controversial forms of public infrastructure investment in developing countries, but little is known about their impact. This paper studies the productivity and distributional effects of large dams in India. To account for endogenous...

The Nile as a transboundary river attracts worldwide attention. 85% of the river originates in Ethiopia. However, Ethiopia has historically been excluded from using this resource for development purposes. Since 2011, Ethiopia has been building a dam on the Blue Nile. However, downstream...

In the 21st century Ghana has seen the revival and construction of dam projects which had previously been stalled for decades as a result of financing constraints and socio-environmental concerns. What has enabled Ghana’s contemporary dam-building revival? What are the risks and benefits? This...
