Land resource management on environment and sustained basis for agricultural land use planning using landform and land evaluation approach (a case study in North Barito District, Central Kalimantan Province)

Abstract

One of strategic policies that has been established in order to achieve and maintain food security in Central Kalimantan is opening the potential lands for agriculture. North Barito district as one several districts in this province, with total areas of 998,908 hectares, has the availability of arable lands for agricultural development. This study was then carried out to provide data and information for appropriate land and environment management through proper agricultural land use planning. Landform approach through digital elevation model (DEM) analysis and land evaluation procedure were used to define land allocation on sustained basis. The technology of geographic information system (GIS) and remote sensing were also employed to produce geospatial data to support land evaluation purpose. The result provide geospatial management of land and environment concept that can be implemented as basic consideration for agricultural planning especially in land use. In the case of North Barito, the region can be allocated for agricultural system of estate crops, food crops and forest ecosystem with each total area of 558,319 hectares (55.89%); 221,920 hectares (22.22%); and 218,669 hectares (21.89%), respectively. Specific program and policy can then be designed to develop the region for the development of agricultural purposes.
