Drought assessing scenario in bangladesh

摘要

Drought is perhaps one of the most widely investigated climatic events in climate-society interactions, because it directly affects societies through changes in the abundance and availability of food and fiber, water resources and energy supply. Dryness or Drought (in case of extreme dryness) has become an important national issue in Bangladesh in recent years. Analysis on rainfall and temperature data from the year of 1996 to 2000, provided the basis of developing drought maps and this incorporated significant uses of Geographic Information System (GIS). Analyzing the changing pattern of dryness condition between two years (1996 and 1999), nature of the slope of dryness has been identified for different regions of the country. Drought assessment will assist in decision making as well as policy planning especially for the agriculture sector of the country.
