Sustainable Development and Agriculture in the United States
Introduction
Agriculture in the United States eludes easy categorization and description. The system is diverse in climate, geography, crops, and agronomic practices. For example, it includes the truly vast midwestern dryland grain belt as well as some 46 million acres of land in organized irrigation systems. Because this system is built upon the energies of successive waves of immigration, it also reflects a healthy diversity in its cultural approaches to farm production.
Agriculture has received support of one kind or another from the federal government throughout the nation's history. Land, railroads, farm-to-market transportation, scientific research, technology, education, rural infrastructure, electricity, and irrigation water have been provided. It was the Dust Bowl and economic depression of the 1930s, however, that made the federal government the financial partner of "commodity" agriculture which it is today. A significant part of that pattern of subsidy has been in the form of "conservation" practices. Some of these practices, such as terracing, land retirement, and improved forage crops have made important contributions to protection of the natural and human environment. Others, particularly land drainage, have damaged seriously the natural hydrologic environment.
