Yogyakarta city is the provincial capital and administrative center in Yogyakarta. Bantul and Sleman are two districts which directly adjacent to the city of Yogyakarta. Although the city of Yogyakarta only has an area of 32.5 km2 (1.02% of Daerah lstimewa Yogyakarta), but the urban effect exceed that area. The urban phenomenon has spread from the city of Yogyakarta on the sub-districts in Sleman and Bantul district directly adjacent to the city of Yogyakarta. Thisurban sprawl will potentially disrupt food security in Yogyakarta, especially in the sub-districts themselves.
Study area in this research is the sub-districts in Sleman and Bantu! directly adjacent to the city of Yogyakarta, which are Mlati, Depok, Gamping, Banguntapan, Kasihan, and Sewon. This research used secondary data obtained from Districts in Figures published by Statistics Indonesia. Analysis of the data showed that the wetland area on the outskirts of the city of Yogyakarta in general has decreased from 2003 to 2013. The decline in land area causes a decrease in rice production. In fact, the number and density of population in this period increased which will potentially be a problem for maintaining people’s needs of food within the sub-districts. Solutions that can be done are (1) to implement consistencyof regional planning to the areas that have been designated as agricultural land, (2) take firm action against any violation of the regional planning, and (3) provide incentives for farmers who still maintain their farm by giving them tax-free policy.
