註釋U.S. land and water resources are analyzed as a basis for projecting national agricultural cropland and other land needs to the year 2000. Impact of changes in technology and resource development as well as environmental and institutional factors affecting the availability of these natural resources are discussed. Emphasis is placed on the continuing responsibility of federal, State, and local governments to assess the adequacy of our natural resources to meet future needs and to improve the quality of the environment.
