This imagery was combined with rice land-cover classification data from the Landsat satellite program. FAS used ArcGIS to perform spatial analysis and create maps of the damaged rice production regions of Myanmar. These maps revealed the cyclone's effect on cropland and livestock, the severity of flooding, and the rate of cropland recovery. The United Nations and nongovernmental organizations (NGO) are using the maps to evaluate the scope of the cyclone's impact. The information is also been of great interest to the international agriculture industry for determining market impacts.
"Our GIS maps and flood classification data show that the areas originally inundated by the storm account for approximately 1.7 million hectares of rice, 24 percent of the national rice area, or roughly 2.5 million tons of rice production on a milled basis," says FAS international crop assessment analyst Michael Shean. "The core region most severely damaged by the tidal wave and high winds, however, accounted for approximately 900,000 hectares of rice land, 13 percent of the national rice area, and roughly 1.35 million tons of milled rice production. In addition, field reports from inside the affected region indicate that within these rice production areas, large numbers of villages were destroyed along with much of their food stocks, livestock, and farming supplies."
A commodity intelligence report and maps issued June 10, 2008, demonstrate that approximately 80 percent of the original inundated rice production area is still affected by some degree of flooding, though conditions in the core damage zone had improved considerably, with only 418,000 hectares, or 46 percent of the original area, still showing flood effects. FAS will continue to produce reports and maps and perform analysis of Myanmar's rice production re
