From page 75... ... In a preliminary study in 1974, the Economic Research Service of the United States Department of Agriculture estimated future production of cotton lint under a series of alternative assumptions (Quance 1974; Smith et al, 1974) Its Agricultural Baseline projection assumes a medium growth (series E) Read the entire page →
From page 77... ... In this projection, a declining demand indicated by a per capita consumption dropping from 16 pounds in 1974 to 14 in 1985 and to 12 pounds in 2000, coupled with little change in per-acre yields, would result in a decline in acreage planted to cotton from a present 13 million acres to slightly more than ten million acres. A more realistic scenario would include a continuing rise in yields per acre. Read the entire page →

From page 81... ... In terms of acreage, cotton currently accounts for 13 million, or less than 4 percent of the total United States crop acreage of 360 million acres. The projected acreage is expected to drop to 10 million acres by 2000 in the Economic Research Service projections and to range from 11.8 to 14.2 million acres in the low and high levels of the Cotton Council of America projections.
