Abstract
The research objective is to drought the risk of mapping in Ninh Thuan for agricultural production through multiple-criteria decision-making (MCDM). The study uses data from Ninh Thuan hydro-meteorological stations from 1986 to 2020. The research used the Fuzzy Analytical Hierarchy Process (FAHP) and TOWS analysis to build a drought risk mapping and solutions. The research results have created maps of the Standard Precipitation Index (SPI), Moisture index (MI), Rainfall Anomaly Index (RAI), map of rainfall distribution, and the general map of drought in the period 1986 - 2016. Besides, the study has also proposed priority solutions for agricultural production in different periods through the pairs of the TOWS matrix. Research results have proved that qualitative and quantitative methods are necessary. This combination helps evaluate criteria and propose more objective solutions when performing a task. Besides, the results can be applied in many different fields in the future, although there are still some weaknesses. However, these weaknesses can be overcome when adding other techniques in the MCDM group with fuzzy logic.
