What is water-related poverty, and how does it vary over space?
As part of the CGIAR Challenge Program on Water and Food, we analyzed water-related poverty, and its correlates, across the Niger Basin, West Africa. We compared findings across 10 river basins over three continents to identify broad connections between water, agriculture and poverty. Conducted in collaboration with colleagues at CSIRO and Institut de recherche pour le développement (IRD).

What is the impact of climate change on Australian agriculture, and can markets help mitigate water resources uncertainty?
We investigate the likely impacts of climate change on irrigated agriculture in the Murray Darling Basin, Australia’s most important food growing area. We use a mathematical programming model to predict land use change and economic effects of reduced water availability under different policy settings. We consider the merits and challenges of using markets to manage water resources under future uncertainty. After a rocky two decades of reform, the Australian water market is the most effective and expansive in the world. Conducted in collaboration with colleagues at CSIRO.

What institutional innovations can help alleviate the economic costs of groundwater depletion?
We undertake a cost-benefit analysis of alternative approaches to groundwater management in the Diamond Valley, Nevada. Rapid groundwater depletion is forcing the State Government and irrigators to consider the curtailment of existing water rights. The costs and benefits of different curtailment options – including innovations such as trading systems – are assessed using a mathematical programming model. We consider the distribution of impacts on farmers with different types of water rights. Conducted with colleagues at the Nicholas Institute for Environmental Policy Solutions.
