Quantification of agricultural land balance sheet of Purworejo District in 2009 and 2018

Abstract

Some districts in Central Java have problems regarding the shrinkage of agricultural land area and a high decrease in the number of farm households. The increase in population and economic development is one reason for the increased demand for land to convert agricultural land. The faster rate of land use change can affect the conditions of domestic food availability in an area, so it is important to quantify the area of agricultural land to monitor changes in land area. This research aims to calculate changes in agricultural land area through the balance of agricultural land resources. This research was conducted with quantitative methods and analyzed descriptively and spatially. Agricultural land is calculated using the land resource balance through a skronto table in 2009 and 2018. The results show that a decrease in area is more dominant than an increase in land area. The largest decrease in total land area occurred in tegal/farm area of 21.12 % and paddy field area of 3.43 % of the previous area. Spatially, changes of land area influenced by land conversion with two factors, namely physical condition and accessibility of the area.
