A-GIS BASED POTENTIAL EVALUATION OF NAPIER GRASS PLANTATION IN THAILAND : According to the Alternative Energy Development Plan (AEDP 2012-2021) initiated by the Ministry of Energy (MoE), the future power generation sourced by alternative energy resources is planned to be increased up to 25% of total power generation in next 10 years. Among various alternative energy resources, biogas will contribute as high as 3600 MW of which 83% or 3000 MW will be produced from Napier grass. By an approximate estimation, an enormous area of 480,000 ha throughout Thailand is needed for Napier grass plantation in order to achieve the AEDP 2012-2021’s target. This study aimed to develop a method in locating suitable areas of Napier grass plantation and estimating the potential of its productivity using geographic information system (GIS) technique via ArcGIS software. Integrating with statistical data obtained from pilot plantation sites, it was found that the total suitable area, including all different classifications was 51,324,101 ha and the total yield potential was 30,784,515 tons/year. The largest usable area was found at North-Eastern region which approximately 45% of total usable area.
