Spatial landuse planning for developing sustainable food crop areas using land evaluation approach and GIS application (a case study of Pulang Pisau Regency, Central Kalimantan)

Abstract

Abstract The need of landuse planning become apparent since the lands have the opportunity to be developed. Appropriate landuse planning based on spatial land resource data management is then required, in order to achieve sustainable landuse. The objective of this study was to design and allocate appropriate agricultural land regions for land use policy through extensification and intensification programs in order to support sustainable food crops development areas. The procedure of land resource evaluation consisting of land capability evaluation (LCE) and land suitability evaluation (LSE) was applied to determine land allocation of arable lands for rice farming development. The use of geographic information system (GIS) technology was also employed not only for spatial data management but it can also be applied to support decision making within establishing landuse planning. In the case of Pulang Pisau District, land allocation for extensification and intensification regions are mainly found in southern part and mostly located at watershed areas with each total area of 380,261 ha (36.81%) and 29,941 ha (2.90%), respectively. In order to support these potential areas, specific programs can then be formulated to increase the yield and productivity for these regions.
