Landuse change and its impact on rice productivity in Sleman Regency 2007-2017

Abstract

Landuse change is a serious phenomenon which faced by some of the suburban areas. Sleman Regency is one of regencies that is located in suburban area or outskirts of Special Region of Yogyakarta. The imbalanced between the need or the demand and the availability of land in Special Region of Yogyakarta, trigger a city expansion to the surrounding areas, especially in Sleman Regency. The purpose of this research is to study and to examine the impact of landuse change towards to the paddy productivity in Sleman Regency. The landuse analysis was performed by comparing the RBI map of Sleman Regency in 2007 and the RBI map of Sleman Regency in 2017. The result of the research showed us that during 2007-2017 period, the decreasing areas were fields by 0.93%, shrubs by 0.12%, and rice fields by 47.5%. Landuse that experienced increase in area were buildings by 2.89%, plantations by 12.62%, and settlements by 34.26%. The decreasing area of paddy fields did not significantly reduce the productivity of the rice. Rice production from 2007-2017 period is stable and tends to be increase. That is because the area of harvested land from 2007-2017 has also increase due to the agriculture diverification program in Sleman Regency. This research shows us the projection of paddy productivity until 10 years later from 2017.
