The agrarian reform execution considered some factors, including land quality, land availability, market access, and others. One of agrarian plus programs is land redistribution. To speed up land redistribution program, spatial information technology can be utilized due to time efficiency in handling coverage areas. This research aims to test important variables to identifY available land for allocation supporting agrarian reform program. The research was conducted in Riau and West Java province. Spatial database was first developed then followed by designing land availability from land status, physical suitability, occupation status, and land cover. By employing multi-criteria evaluation in GIS then available land was determined The research showed application of different combination of variables generated different land acreages. Acreages of available land on West Java and Riau showed different minimum requirement for standard of living. the difference on standard of living, price structures and land fertility implied to difference on minimum acreage to support farmers' living. The farmers of West Java required less land to support their standard of living than farmers in Riau. The available land of Riau distributed in all kabupatenslkota, while in West Java there were some kabupatens lack of available land for agrarian reform, for instances in Bekasi, Cirebon, Indramayu and Depok.
