Agriculture is a vital sector of Pakistan's economy and accounted for 25.9 percent of GDP in 1999-2000, according to government estimates. The sector directly supports three-quarters of the country's population, employs half the labor force, and contributes a large share of foreign exchange earnings. The main agricultural products are cotton, wheat, rice, sugarcane, fruits, and vegetables, in addition to milk, beef, mutton, and eggs. Pakistan depends on one of the world's largest irrigation systems to support production. There are 2 principal seasons. Cotton, rice, and sugarcane are produced during the kharif season, which lasts from May to November. Wheat is the major rabi crop, which extends from November to April. The key to a much-needed improvement of productivity lies in a more efficient use of resources, principally land and water. However, change is dependent on the large landowners who own 40 percent of the arable land and control most of the irrigation system, which makes widespread reform difficult. Assessments by independent agencies, including the World Bank, show these large landholdings to be very unproductive. Pakistan is a net importer of agricultural commodities
Pakistan is one of the world's largest producers of raw cotton. The size of the annual cotton crop is a crucial barometer of the health of the overall economy, as it determines the availability and cost of the main raw material for the yarn-spinning industry, much of which is concentrated around the southern port city of Karachi. . A major problem is that the cotton crop is highly susceptible to adverse weather and pest damage, which is reflected in crop figures.
Pakistan is a major rice exporter and annually exports about 2 million tons, or about 10 percent of world trade. About 25 percent of exports is Pakistan's famous fragrant Basmati rice. Rice is Pakistan's second leading source of export earnings. Pakistan's main competitors in rice trade are Thailand, Vietnam, and India.
Tobacco is grown mainly in the pakhtoonkhwa and Punjab and is an important cash crop.
important cash crop. Yields in Pakistan are about twice those for neighboring countries largely due to the extension services provided by the industry. Quality, however, is improving only slowly due to problems related to climate and soil. Farmers have started inter-cropping tobacco with vegetables and sugarcane to increase returns. About half of the total production is used for cigarette manufacturing and the remainder used in traditional ways of smoking (in hand-rolled cigarettes called birris, in water pipes, and as snuff). The share of imported tobacco is increasing gradually in response to an increased demand for high-quality cigarettes.
Minor crops account for only 5 percent of total cultivated area; these include oilseeds (sunflower, soybean), chilies, potatoes, and onions. Domestic oilseed production accounts only for about 25 percent of Pakistan total edible oil needs. As a result, Pakistan spends more than US$1 billion annually in scarce foreign exchange to import edible oils, while its oilseed processing industry operates at less than 25 percent of capacity due to an inadequate supply of oilseeds.
Pakistan's fishing industry is relatively modest, but has shown strong growth in recent years. The domestic market is quite small, with per capita annual consumption of approximately 2 kilograms. About 80 percent of production comes from marine fisheries from 2 main areas, the Sindh coast east from Karachi to the Indian border, and the Makran coast of Baluchistan. Ninety percent of the total marine catch is fish; the shrimp which constitute the remainder are prized because of their greater relative value and demand in foreign markets. .
Livestock accounts for 40 percent of the agricultural sector and 9 percent of the total GDP. Principal products are milk, beef, mutton, poultry, and wool. During 1999, the livestock population increased to 120 million head. That same year Pakistan generated 970,000 tons of beef, 640,000 tons of mutton, and 190,000 tons of poultry.
Forests cover an area of 4.2 million hectares or about 5 percent of the total area of Pakistan. The principal forest products are timber, principally for house construction, furniture, and firewood.
