Book Description
California experienced severe water supply shortages in 2009, which led to economic disruption across the state, incl. losses in agricultural areas in the western portion of the Central Valley ¿ areas already experiencing declines in the housing industry and the economic downturn in general. At the same time, several fish species whose habitat lie at the heart of California¿s water supply system and throughout its northern rivers are in decline and some face the possibility of extinction. This situation too has had economic implications, resulting in job and income losses in northern California. Contents of this report: (1) Intro.; (2) What is Drought?; (3) Drought in California; (4) Regulatory Restrictions Affecting Water Deliveries; (5) California Water Rights. Illus.

Book Description
The underlying concept of the paper is that the amount of precipitation required for the near-normal operation of the established economy of an area during some stated period is dependent on the average climate of the area and on the prevailing meteorological conditions both during and preceding the month or period in question. A method for computing this required precipitation is demonstrated.

Book Description
Drought is a natural hazard with potentially significant societal, economic, and environmental consequences. Public policy issues related to drought range from how to identify and measure drought to how best to prepare for, respond to, and mitigate drought impacts, and who should bear such costs. This report provides information relevant to drought policy discussions by describing the physical causes of drought, drought history in the United States, examples of regional drought conditions, and policy challenges related to drought. What is drought? Drought is commonly defined as a lack of precipitation over an extended period of time, usually a season or more, relative to some long-term average condition. While the technology and science to predict droughts have improved, regional predictions remain limited to a few months in advance. History suggests that severe and extended droughts are inevitable and part of natural climate cycles. What causes drought? The physical conditions causing drought in the United States are increasingly understood to be linked to sea surface temperatures (SSTs) in the tropical Pacific Ocean. Studies indicate that cooler-than-average SSTs have been connected to the severe western drought in the first decade of the 21st century, severe droughts of the late 19th century, and precolonial North American “megadroughts.” The 2011 severe drought in Texas is thought to be linked to La Niña conditions in the Pacific Ocean. What is the future of drought in the United States? The prospect of extended droughts and more arid baseline conditions in parts of the United States could suggest new challenges to federal water projects, which were constructed largely on the basis of 20th century climate conditions. Some studies suggest that the American West may be transitioning to a more arid climate, possibly resulting from the buildup of greenhouse gases in the atmosphere, raising concerns that the region may become more prone to extreme drought it was in the 20th century. Some models of future climate conditions also predict greater fluctuations in wet and dry years. California's 2007-2009 drought exacerbated ongoing tensions among competing water uses. While drought is most common in California and the Southwest, drought also can exacerbate water tensions in other regions. For example, the 2007-2008 drought in the Southeast heightened a long-standing dispute in the Apalachicola-Chattahoochee-Flint River (ACF) basin. Both California and the ACF are again experiencing drought conditions, as are the Rio Grande and Upper Colorado River basins. What are some drought policy challenges? Although the impacts of drought can be significant nationally as well as regionally, comprehensive national drought policy does not exist. Developing such a policy would represent a significant challenge because of split federal and non-federal responsibilities, the existing patchwork of federal drought programs, and differences in regional conditions and risks. While a comprehensive national policy has not been enacted, Congress has considered and acted upon some of the recommendations issued by the National Drought Policy Commission in 2000. In coming years, Congress may review how federal agencies such as the U.S. Army Corps of Engineers and the Bureau of Reclamation respond to droughts. Congress may also assess other federal programs or choose to reassess the National Drought Policy Commission's recommendations.

Book Description
This assessment provides input to the reauthorized National Integrated Drought Information System (NIDIS) and the National Climate Assessment (NCA), and it establishes the scientific foundation needed to manage for drought resilience and adaptation. Focal areas include drought characterization; drought impacts on forest processes and disturbances such as insect outbreaks and wildfire; and consequences for forest and rangeland values. Drought can be a severe natural disaster with substantial social and economic consequences. Drought becomes most obvious when large-scale changes are observed; however, even moderate drought can have long-lasting impacts on the structure and function of forests and rangelands without these obvious large-scale changes. Large, stand-level impacts of drought are already underway in the West, but all U.S. forests are vulnerable to drought. Drought-associated forest disturbances are expected to increase with climatic change. Management actions can either mitigate or exacerbate the effects of drought. A first principal for increasing resilience and adaptation is to avoid management actions that exacerbate the effects of current or future drought. Options to mitigate drought include altering structural or functional components of vegetation, minimizing drought-mediated disturbance such as wildfire or insect outbreaks, and managing for reliable flow of water.

Book Description
Recognizing drought as a characteristic feature of the North American climate, the contributors to this volume seek to organize available evidence of both prehistoric and modern drought events and to provide information on the severity of droughts, especially those which have occurred since weather records have been kept. The impacts of modern-era droughts on production and the potential impact of future droughts on the productivity of North American agriculture are examined. The authors explore the effeats of past droughts on the social, cultural, and political life of the population; the possible effects of drought on today's energy- and techno logy-intensive society; and the ramifications of drought for the national economy. The social and political strategies that local, state, and federal governments may use to meliorate the effects of drought are also considered, as are some possible technological defenses against drought—weather modification, expanded irrigation, new techniques of water harvesting and storage, and new agronomic adaptations. Finally, the critical question of whether future droughts can be forecast is examined.
