Remote sensing and GIS applications for sustainable food agricultural land mapping and supporting the preparation of regional spatial plans (case study of Badung Regency)

Abstract

Local Government (LG) provincial and district/city in Bali until now does not have a Regional Regulation (RR) on determination of Sustainable Food Agricultural Land (SFAL). This is related to the provision of land for non-agricultural development permits. Map of SFAL has been established as a condition for the drafting and revision of the Spatial Plan (SP) [1]. Multi-analytical research methods: super impose analysis of thematic maps, ten thematic maps of physical and environmental conditions (river basin area, land use, irrigation, relief, rainfall, elevation, regional spatial planning, land suitability, productivity, and distance from city center) will be analysed and scored to numerically scoring (numerical classification), toolbox - analysis tools-overlay-intersect. Materials and tools: Quick Bird satellite images 2013 and QGIS software 10.3. Field survey to compile a data base of SFAL at each location. Map and data base SFAL obtained from the analysis of thematic maps of physical and environmental conditions. SFAL 9,642.76 ha was recommended for the revision of SP for 2013-2033; SFAL = 8,824.36 ha is recommended to reflect SP year 2034-2054 ha and 6,510.11 ha for the drafting of SP year more than 2055 location are in the. SFAL location are in the upstream and center (Petang, Abian Semal, and Mengwi District). Subak rice field that can be converted 829.41 ha - 3,143.66 ha is located in the districts of Kuta and Nort Kuta. Remote sensing and GIS technology can be used for SFAL mapping, through the classification of numerical thematic maps of the physical and environmental conditions of the region.
