Farming is Pakistan's largest economic activity. In FY 1993, agriculture, and small-scale forestry and fishing, contributed 25 percent of GDP and employed 48 percent of the labor force. Agricultural products, especially cotton yarn, cotton cloth, raw cotton, and rice, are important exports. Although there is agricultural activity in all areas of Pakistan, most crops are grown in the Indus River plain in Punjab and Sindh. Considerable development and expansion of output has occurred since the early 1960s; however, the country is still far from realizing the large potential yield that the well-irrigated and fertile soil from the Indus irrigation system could produce. The floods of September 1992 showed how vulnerable agriculture is to weather; agricultural production dropped dramatically in FY 1993.
Land Use
Pakistan's total land area is about 803,940 square kilometers. About 48 million hectares, or 60 percent, is often classified as unusable for forestry or agriculture consists mostly of deserts, mountain slopes, and urban settlements. Some authorities, however, include part of this area as agricultural land on the basis that it would support some livestock activity even though it is poor rangeland. Thus, estimates of grazing land vary widely--between 10 percent and 70 percent of the total area. A broad interpretation, for example, categorizes almost all of arid Baluchistan as rangeland for foraging livestock. Government officials listed only 3 million hectares, largely in the north, as forested in FY 1992. About 21.9 million hectares were cultivated in FY 1992. Around 70 percent of the cropped area was in Punjab, followed by perhaps 20 percent in Sindh, less than 10 percent in the North-West Frontier Province, and only 1 percent in Baluchistan.
Since independence, the amount of cultivated land has increased by more than one-third. This expansion is largely the result of improvements in the irrigation system that makes water available
