| Abstract | The study was conducted to evaluate land of Upland farming system in Playen Sub District, Gunung Kidul, Y ogyakarta Province, Indonesia. Base on F AO framework, land evaluation has done by integrated application of GIS technology and socio-economic analysis combine with field data. The main objective of this study was to design an appropriate land suitability classification for selected of three upland crops including upland rice, soybean, and ground nut, which regard to the best use of land given environmental, social and economic constraints for improving quality of live the farmers. Landuse, land form, geology, slope and soil maps were produced using ARC/Info program packages. By overlay function, physical land suitability classifications for selected upland crops were classified, regard to F AO framework. Result showed that 41 . 5 percent of total areas is moderately suitable (S2) for upland rice, and about of 28.1 percent is marginal suitable (S3), which limitation on rooting condition. Result of land suitability analysis for soybean and ground nut reveals that study areas have land marginal suitable (S3) of 45 percent, which limitation on rooting condition and terrain conditions. The dominant of limitation factors on land not suitable (Nl and N2) of crops were rooting condition, the others limitation factors were terrain condition like slope terrain, rock outcrops, surface stoniness, and soil erosion. However, Some areas are found lack of nutrients for crops. Integration of land evaluation and farming systems analysis can improve current practices in landuse planning as an aid for sustainable landuse, sustainable agriculture and rural development. These integration have provided an efficient and effective method of analysis for land use planning. Land evaluation with GIS support given spatial analysis, however, farming system analysis has given socio-economic condition of farmers. Based on socio-economic analysis, the averages of land holding size in study areas are small farm category which are primarily devoted to the subsistence. These farms are characterised by subsistence and commercial system. The subsistence of farm is characterised by agriculture work which carried out by family labour, however, most of farm subsistence requirement are met directly from farm production (rice crop). The major problems of land resource in the study area, and continued of farmers activities depending on forest resource are lead to deforestation, soil erosion, and land degradation. The proposed landuse planning in the study area is settlement (21,2% of total areas ); agriculture land (29.4%); agroforestry area (26.3% ); and forest land (23 .1 %). |
