In the Middle East and North Africa, food security and water security are tightly entwined. In particular, choices about the extent to which food security policies rely on trade rather than domestically produced staples have stark consequences for the region's limited water resources. This paper...

Climate-driven water variability is a natural phenomenon observed across river basins, but predicted to increase due to climate change. Environmental change of this kind may aggravate political tensions, especially in regions that are not equipped with an appropriate institutional apparatus....

This paper assesses the impact of water supply variability on treaty cooperation between international bilateral river basin riparian states. Climate change is anticipated to change the variability of water supply, as well as its expected magnitude. Previous studies have focused mainly on water...

This paper summarizes the methods and findings of the hydrological assessment component of the project studying likely impacts of climate change on water resources and agriculture in Africa. The first phase of the study used a version of a conceptual rainfall-runoff model called WatBal (Water...

Although water variability has already been observed across river basins, climate change is predicted to increase variability. Such environmental changes may aggravate political tensions, especially in regions that are not equipped with an appropriate institutional apparatus. Increased...

The paper presents the development and implementation of a geo-spatial model for mapping populations' access to specified types of water and sanitation services in Nigeria. The analysis uses geo-located, population-representative data from the National Water and Sanitation Survey 2015, along...

Management of common-pool resources in the absence of individual pricing can lead to suboptimal allocation. In the context of irrigation schemes, this can create water scarcity even when there is sufficient water to meet the total requirements. High-frequency data from three irrigation schemes...

This paper provides new evidence on how effectively piped water consumption subsidies are targeting poor households in 10 low- and middle-income countries around the world. The results suggest that, in these countries, existing tariff structures fall short of recovering the costs of service...

Utilities the world over grapple with how to set prices to recover fixed costs. This paper considers optimal utility provision and pricing when consumers form habits without being aware of it. Data from a multi-year pricing experiment among nearly 1500 rural piped water customers in Vietnam...

The main purpose of this paper is to argue that the optimal design of regulation of water and sanitation monopolies should be the outcome of a detailed diagnostic of the institutional constraints impacting the ability of the operator -- whether public or private -- to deliver the services....
