Spatial Representation Of Agroclimatology In A Study Of Agricultural Drought, Olga V. Wilhelmi, Kenneth Hubbard, Donald A. Wilhite

Agricultural drought is the leading cause for crop failure throughout the world. In the USA, significant impacts of recent droughts on agricultural production indicate the continuing vulnerability of the country to drought. This paper presents a methodology for spatial representation of the agroclimatic component of agricultural drought vulnerability. This methodology was developed as a part of an integrated assessment of drought vulnerability. For the spatial analysis, the state of Nebraska was selected as a study area because of the considerable variation in climatology, soil characteristics, land use, and cropping patterns. The underlying approach assumes that the best spatial characterization of …

Assessing Vulnerability To Agricultural Drought: A Nebraska Case Study, Olga V. Wilhelmi, Donald A. Wilhite Jan 2002

Assessing Vulnerability To Agricultural Drought: A Nebraska Case Study, Olga V. Wilhelmi, Donald A. Wilhite

Drought Mitigation Center: Faculty Publications

Recent drought events in the United States and the magnitude of drought losses indicate the continuing vulnerability of the country to drought. Until recently, drought management in many states, including Nebraska, has been largely response oriented with little or no attention to mitigation and preparedness. In 1998, Nebraska began to revise its drought plan in order to place more emphasis on mitigation. One of the main aspects of drought mitigation and planning is the assessment of who and what is vulnerable and why. This paper presents a method for spatial, Geographic Information Systems-based assessment of agricultural drought vulnerability in Nebraska. …
