This paper uses two years of agriculture census data to build a panel dataset that consists of all the small towns in Bhutan. This dataset is used to estimate the impact of irrigation gaps and drought on the yields of paddy, maize, and other crops. The paper compares the estimated impacts from a panel fixed effects model and a spatial first differences model. The findings show that irrigation gaps reduce paddy yields and droughts reduce maize yields. Estimates from the spatial first differences model are found to be consistent relative to those from the panel fixed effects model. The paper further finds that water constraints reduce yields of vegetable crops, and other constraints, such as labor shortages, wild animals, insects, and diseases, also reduce the yields of cereal crops.

The current state of knowledge on climate change and water points to predominantly negative effects. This paper reviews the literature on these effects by geographical region and notes the differences as well as the uncertainties. An important feature is the fact that the climate effects will occur on top of water scarcity that currently prevails in many parts of the world. The impact of climate change on scarcity is present but generally small compared to the impact of the socioeconomic factors. Changes in efficiency of water use could make a big contribution to water problems, including those caused by climate change. In-depth estimates of damages from climate change related to water have been made to 2060 and, less accurately, to 2100. The 2060 estimates indicate that the impacts from water supply changes or changes in water-related extreme events and marine flows add up to about 1.5 of GDP in 2060 in the absence of mitigation or adaptation. This average figure, however, may be an underestimate of a number of reasons. Estimates to 2100 of potential damages in economic terms are even more uncertain but there are strong reasons to believe they will be greater as a percentage of GDP, perhaps around 10 globally and possibly even higher. Adaptation can make a major contribution to reducing damages from climate change for all mitigation scenarios, and more so when mitigation is absent or limited. Adaptation will require both private and public actions.

The aim of this paper is to provide a strategic overview of a decade of experience in supporting public administrations in their efforts to confront excessive groundwater resource exploitation for agricultural irrigation. Special emphasis is put on a series of on-the-ground pilot projects mainly in South and East Asia and Latin America, which are profiled through a series of boxes introduced in the paper. In these pilots' appropriate packages of technical, economic, institutional and social measures, in the main selected through use of a 'pragmatic framework' for groundwater resource management, have been introduced with agreement of stakeholders in an attempt to promote more sustainable groundwater use in agricultural irrigation. They have achieved varying degrees of success but do provide hope and orientation for the future in this important aspect of water resource management.
