Abstract

The annual precipitation in the Southern Central Region is unevenly distributed over time and space, so drought and severe water shortage usually occurs in dry season almost every year. In the last three  years 2014 - 2016, due to El-Nino phenomenon, which directly affected the Southern Central Region, servere  precipitation and high rising temperature causing drought and water shortage have resulted in extreme damage to production and people's lives. As prolonged drought along with water stored in the irrigation system does not meet the water irrigation amount for agricultural production, many areas of rice land have been stopped in production; the areas of ​​other crops have been lacked of irrigation water at mid and late seasons. This paper presents the tools for water resources management for supporting decision-making on water supply for agricultural production that actively contributes to prevent drought in the Southern Central Region. The tools are mainly focused on remote sensing data to calculate and monitor water resources for production planning as well as actively responding to droughts in the area.
