Abstract:
Food security is a global issue. FAO studies show 925 million people worldwide hunger. Population growth, land conversion, reduction of investment and low agricultural technology led to agricultural production is not optimal and inhibition of food security. The purpose of the study was to determine the long-term food security optimization model-based environment, while specifically determine the suitability of food security and agricultural land. Food security in question is the level of food sufficiency. Environmental base in research focused on the physical and socio-economic variables. Physical variables include the shape of the land, land use, slope, soil and climate. Socioeconomic variables include production (rice, maize and potatoes), resident. Physical and socio-economic variables obtained from secondary data (CBS, BIG and BMKG) and primary (interviews and surveys). The location determined by purposive sampling research on volcanic slopes of Merapi. The research sample is based on land units of the overlay form of land, land use and slope. Analysis of basic physical research analysed with GIS and survey the field while the social economy through quantitative analysis of food adequacy calculation. The analysis showed that the suitability of land on the slopes of Merapi volcanic included in the category suitable (S1, S2 and S3) and the level of food sufficiency in the category of surplus unless the District Mlati and Depok. This is because the two districts located on the outskirts of Yogyakarta city with a high population and a low amount of agricultural land. However, food security in all regions is optimized by minimizing the bias is still a limiting factor that increases food security by increasing the number of production.
