EVALUATION OF AGRICULTURAL DROUGHT USING LSWI, MSI INDICES: CASE STUDY IN THUAN NAM DISTRICT, NINH THUAN PROVINCE

Abstract

This study was applied Land Surface Water Index (LSWI) and Moisture Stress index (MSI) based on Landsat-7, Landsat-8 images data from the 2004-2016 period to observe and evaluate drought situations in Thuan Nam district, Ninh Thuan province. The results show that LSWI and MSI reflect the level of drought consistent with the drought events recorded from the ground monitoring station data in the years 2004-2005, 2015- 2016. This paper proposes that LSWI, MSI can be used to monitor agricultural drought, as well as use these two indices for building drought prediction models.
