Due to its low economic efficiency, irrigation water is often regarded as a major portion of regional water demand in the national water resources master plans and also the potential sources for supporting municipal and industrial (M&I) sectors during droughts. However, farmers and the agricultural sector often did not get proper compensation on water transferring to M&I sectors. This study proposes a framework for risk analysis of agricultural droughts. Through more effective drought risk allocation among sectors, water managers could look after both sides, including agricultural and economic development. The water demand estimation is an important part for building a drought allocation model. Regional water demand involves human activities and spatial-distributed attributes, such as land-use, land cover, infrastructures, etc. Therefore, GIS is used to capture these spatial variations. GIS-based irrigation water demand estimation model has been established last year. The purpose of the study in this year is to build a GIS-based M&I water demand model. Despite many efforts done on the research of M&I water demand for individual industrial classes, per capita or per unit area water demand are used as basis for most regional water demand estimations. A framework is proposed in this year for capture of divergences of M&I water demands among different types of water-use at different locations. GIS is used for data management of related geographic and census data. A model is proposed to include various regression forms for M&I water demand estimation. Graphic user interface is used for easy of use and related decision information for regional water demand planning are presented to the decision maker through charts and tables. A better regional planning decision may be made through the provided information.農業水資源規劃乾旱調配地理資訊系統農田水利會農業用水移轉agricultural water resources planningdrought allocation,geographic information system (GIS)irrigation associationirrigation water transfer
