The U.S. Agricultural Commodities in Drought website provides information about the percentage of growing area that is affected by drought for various agricultural commodities, according to the U.S. Drought Monitor.
Statistics are calculated each week by overlaying U.S. Drought Monitor data on drought extent and severity over maps of major and minor agricultural areas for several commodities. Agricultural data are obtained from the U.S. Department of Agriculture National Agricultural Statistics Service Census of Agriculture, which is undertaken every five years.
Users can view statistics, time series, and maps for both row crops and livestock & forage, as well as drought monitoring, risk management, and planning resources for speciality crops.
In addition, users can view current and historical crop progress reports from the U.S. Department of Agriculture. During the growing season, these maps are generated each week by the USDA Office of the Chief Economist, based on Crop Progress report data from the USDA National Agricultural Statistics Service, to facilitate internal USDA assessments of domestic crop progress and conditions.
