Abstract

Land allocation for agricultural lands is required when the region have potency to be developed while the same time, conservation aspects are still considered. Central Kalimantan Province with total areas of 15, 451, 287 hectares has potential land available for agricultural development. At initial stage, with a landscape scale, land resource potential is needed to be assessed for planning purposes. The aimed of this study was to design the spatial concept of agricultural landscape planning on sustained basis. Methodology used in this include concept of land capability evalution (LCE) approach and geographic information system (GIS) application. The result of evaluation showed that Central Kalimantan was classified into 6 land capability classes i.e class II, III, IV, VI, VII, and VIII with several limiting factors such as peat depth, drainage, slope, and texture. Within GIS environment, the result of spatial analysis shown that total areas of agricultural land region was 9,571,231 hectares or 61.95% of total Central Kalimantan province. This indicates that the lands are still widely available for agricultural development. These areas are located not only in wetlands typology but also found in dryland areas. Specific program that specific to location can then be formulated in order to develop the areas.

Highlights

In spatial planning process, determination of arable lands for agriculture on sustained basis cannot be ignored and should even be considered
This is in line with government policy by establishing a superior sustainable industrial agricultural system based on local resources to increase food self-sufficiency, added value, exports and farmer welfare as a vision of agricultural development
The land capability evaluation (LCE) proposed by USDA (United State Department of Agriculture) was used in which class I, II, III, and IV were suitable for agricultural land utilization, while for class V, VI, VII, and VIII, the lands were established as non-arable lands (Girmay et al, 2018)

Summary

INTRODUCTION

Determination of arable lands for agriculture on sustained basis cannot be ignored and should even be considered. The result of preliminary study showed that the lands that have been opened for agricultural purposes only 3,091,280 hectares or 20% of total areas of Central Kalimantan Province. This indicate that land resources are still available for agriculture with considering the other land use purposes. Land capability evaluation (LCE) is an analysis approach to assess and identify land resources for specific kind of use It can determine capability classes based on potential and limiting characteristics for their sustainable use. The data available was used for LCE and further spatial analysis and this study was conducted to identify land resource potential for agricultural land use and landscape planning purposes. The aimed of this study was to design the spatial concept of agricultural landscape planning on sustained basis
