Abstract

Conversion of agricultural to non-agricultural land use causes a decline in food security. Population density, land productivity, and social welfare are assumed as the factors causing this conversion. This research is aimed not only to know the influence of population density to land use conversion, but also the limit of food self-supporting happened in Badung and Gianyar Districts. Research used correlational method by taking samples from the survey of data in 2005 – 2015, and the population is all sub districts located in Badung and Gianyar districts where the land use conversion took place from year of 2005 up to 2015. Result of analysis using multiply regression shows that population density and social welfare influence the conversion of agricultural to nonagricultural land use. To analyze the limit of food security used variable of population increase, and conversion used exponential equality. The result of analysis shows that limit of food selfsupporting in Badung and Gianyar districts will happen in 12,41 years future or year of 2027 with the size of agricultural land is 15,289.41 ha. Agriculture land consolidation takes place in the subdistricts of Abiansemal, Payangan, Petang, Sukowati, Tampaksiring, and Tegallalang. In the meanwhile, urban land consolidation is in the sub-districts of Blahbatuh, Gianyar, Kuta Utara, and Mengwi. This research can be used as agriculture land consolidation modeling for food security in other areas. Keywords: land use conversion, food security limit, land consolidation.
