Economic Impacts of Cloud Seeding in Southwest Minnesota

David F McGinnis


The purpose of this paper is to identify the economic impacts associated with weather modification in Southwest Minnesota. Although it is recognized that cloud seeding could directly affect many sectors of the economy, the scope is restricted to the direct benefits on agricultural production and first order income and sales taxes returned to Minnesota. Sectors not covered by this report include electrical power generation, municipal and agricultural surface and underground water supplies, recreation, and wildlife. That is, crop yield response to precipitation change estimates are used to derive dollar benefit figures. These dollar benefits are based on the assumption that an actual cloud seeding program could produce timely increases in growing season precipitation equal to those derived hypothetically, or about 1.00" (15 percent above the 50 year median).
