Assessing Pakistan’s rice and cotton crop damage
From late July through August, Pakistan received excessive monsoon rainfall across the country including many of the major rice and cotton growing areas. The extraordinary rainfall triggered severe overland and river flooding. The impact of the floodwater is most severe in Khyber Pakhtunkhwa (NWFP), Baluchistan, Punjab, and the northern districts of Sindh. These provinces have suffered significant loss of cropland and damage to agricultural infrastructure. The major kharif season (June-November) crops are rice and cotton, but a substantial amount of corn, millet, and sorghum is grown during the kharif season as well.
The floodwaters are receding in the mid- and upper-reaches of the Indus Valley but continue to expand in the southern district of Sindh. The final extent of the floodwaters and the resulting damage to crops is still uncertain. The USDA has made a preliminary assessment, based primarily on satellite imagery, which indicates significant crop damage in major rice and cotton areas along the Indus River in Punjab and Sindh provinces.
The USDA forecasts 2010-11 Pakistan rice production at 5.3 million tons, down 19 percent from last month, and down 1.5 million or 22 percent from last year. Area is estimated at 2.4 million hectares, 14 percent down from last month, and down 0.4 million or 14 percent from last year. Yield is forecast at 3.31 tons per hectare, down 5 percent from last month and down 9 percent from last year. USDA damage estimates, based primarily on satellite imagery, indicate rice cropland losses of 400,000 hectares. The rice crop is at various development stages ranging from the early vegetative to the reproductive stage. Satellite-derived vegetative indices indicate that upland cropping areas will benefit from abundant soil moisture, where flooding did not occur.
Cotton production is forecast at 9.3 million 480-pound bales, down approximately 2 percent from last month, and down 0.3 million or 3 percent from last year. Area is estimated at 3.0 million hectares, 2 percent down from last month, and the same as last year. Yield is forecast at 675 kilograms per hectare, down 0.4 percent from last month and down 3 percent from last year. Analysis of satellite imagery suggests cotton cropland losses at around 200,000 hectares. The crop is at various development stages ranging from early vegetative to advanced maturity, and vegetative indices indicate that most upland cropping areas, away from the flooded areas, benefited from abundant soil moisture profiles.
