River restoration and economic development through grassland management:a case study of the James River,South Dakota,U.S.A
Introduction Efforts are currently underway to develop a Watershed Management Plan ( WAM ) for the James River,South Dakota.The purpose of the WAM is to determine potential actions for flood damage reduction and ecosystem restoration.Agricultural uses predominate in the watershed with the river and its tributaries critically important to the region for drainage,irrigation,recreation,and wildlife habitats.Current economic pressure for corn production has resulted in a 14 million acre increase in corn planted in the U.S.This pressure has caused corn production to shift to marginal lands with high erosion potential.A newly proposed policy by the U.S.Department of Agriculture would allow harvesting of conservation grasslands for the production of biofuels.The purpose of this study was to determine if an economically viable compromise could exist that would allow row-crop agriculture to continue on prime agricultural land and grassland to exist on marginal lands.
