Farmland conversion: national lessons for Iowa

, : Farmland conversion: national lessons for Iowa. Professional Geographer 33(1): 113-121

Between 1967 and 1975, cropland in the USA declined by 30.5 M acres, of which 8 M acres were prime farmland. The rising gross farm product continues to outweigh such losses owing to short term adjustments such as irrigation, but longer term measures to conserve farmland are widely urged. Even Iowa, where urban growth is modest, is incurring some loss of superior farmland.
