Abstract
The objective of this study was to analyze the fire risk areas of Kuan Kreng peat swamp during a drought in the non-hunting area of Bo Lo and Thale Noi, specifically in Nakhon Si Thammarat province. Decision based on the Analytic Hierarchy Process was applied with geographic information system techniques (GIS-AHP) to generate a map of the fire risk areas in the Kuan Kreng peat swamp. The study used various physical and environmental factors relating to peat fires. These factors can be divided into 5 main categories, i.e. the aridity of the area, topography, economic and social facet, human activities, and characteristics of the available combustible material. The study results found that most of the Kuan Kreng peat swamp during the drought is at a high risk of fire, estimated to be 375.31 square kilometers or 53.28% of the study area. Critical areas include Hua Sai District, Cha Uat District, and Chian Yai District with 107.73, 77.64, and 74.68 square kilometers, respectively. Most of these areas are ecotones of peat swamp forests connected to agricultural areas which are constantly undergoing development for agricultural preparation. Furthermore, these areas are often grassland, and there is also some overlap between the agricultural areas and the areas dedicated to preservation. This map can be used as a guideline for planning, monitoring, and preventing fires in Kuan Kreng peat swamp forest preservation.
