Policy Practicum: Integrating Water and Land Use Policy in the West: The Missing Link

Catalog description

The western United States is currently experiencing what may be the longest and most severe "megadrought" in modern U.S. history. Current U.S. drought data shows virtually all of the Southwest in severe, extreme, or extraordinary drought. Reservoirs on the Colorado River are reaching record lows, and many farmers throughout the West have had their deliveries cut dramatically or face potentially massive cutbacks. Media discussion of episodic, emergency "droughts" has been replaced by a recognition of the permanent "aridification" of the West under climate change. Resolving the West's growing water crisis will require far greater linkage of water management and land use. Land use drives water demand, while water availability constrains land use. While water and land use are integrally related in fact, water and land-use policies in practice are far from integrated. Developments are approved without reference to water availability, and water agencies often have to scramble to find and fund new projects to augment or conserve water. New land developments or more intensive farming can lead to increased groundwater pumping that can cause neighboring residents' wells to run dry. In other cases, a failure to link water and land use can lead to abrupt building bans and/or emergency rationing. To meet the needs of a more water constrained future under climate change, a more integrated approach to water management and land use is warranted. While John Wesley Powell once recommended close integration of water and land use, western states have historically ignored the imperative. In the past decade or so, some states have ventured more fully into the connection between land use and water. Some states, for example, have enacted "Show Me the Water" statutes that require land developments above a certain size to demonstrate that they have 50 to 100 years' worth of water available…
