Show PART V REGIONAL NEEDS AND DEMANDS Land Requirements Projections of production requirements and the changes brought about by economic considerations will require a significant difference in land use in the future. Blocks of land will be converted from one use to an- other. Increased acreages will be required for urban and industrial, irrigated agriculture, recreation, fish and wildlife, and mineral develop- ment; a large amount of presently grazed land will be retired, and a de- crease will occur in timber and dry cropland. The following tabulation summarizes the projected land needs and the changes from the 1965 condi- tion.
