Spatial analysis for land suitability of Arabica coffee ( Coffea arabica L.) in Bogor District

Abstract

Arabica coffee requires land suitability criteria to support its growth and productivity. If an area has infertile soil conditions and has a climate that is not in accordance with the criteria for growing Arabica coffee, then several alternative solutions are needed to determine the suitability of land in that area. Insufficient knowledge about suitable land can contribute to inefficient land use. Information on land suitability for Arabica coffee in Bogor district is not yet available. This study aimed to analyse the spatial distribution of potential land to develop of Arabica coffee commodities in Bogor. Hence, spatial analysis of land suitability was carried out by utilizing the capabilities of the Geographic Information System used an overlay based on Digital Elevation Model (DEM), agroclimatic variables, physical (adequate depth, soil texture), soil chemical properties (pH, base saturation, cation exchange capacity/CEC and land use information. The proportion of land suitability for Arabica coffee was classified into suitable, marginally suitable, and not suitable consisted of 398.68 ha, 32,209.4 ha, and 266,617 ha of which area size. The potential land for Arabica coffee showed that there was 126 ha for S2 suitability class, 18,681.00 ha for S3 suitability class, and 280,418.58 ha for the non-potential land.
