Daftar Isi:
- The purposes of this research are: (1) to know landuse changes direction between time, area of, proportion of and distribution of converted agricultural lands to building and their influencing factors, (2) to estimate the impacts of the converted agricultural lands to the lost of food productions, lost of agricultural jobs opportunities, and lost of total economic values of multifunctionally of agricultural lands, (3) to estimate the perceptions of communities about: (a) the prospect of agricultural sustainability, (b) farmers' ability to sustain farming and their influencing factors, (c) public awareness of sustainable farming and their influencing factors, and (d) the changes of environmental condition as the impact of the agricultural land conversion to building on the peri urban areas of Yogyakarta City. This research was conducted on the peri-urban areas of Yogyakarta City covering 6 subdistricts regions that consisted of 29 villages or 47 sub-clusters (sub-zones). These areas were splitted to be three zones are Inner Ringroad Zone (ZDRR), Outer Ringroad Zone (ZLRR), and Far Distance from Ringroad Zone (ZJRR). There are two analysis units in this research namely (i) farmer or nonfarmer responden as the individually unit and (ii) each sub-cluster as the area unit. The samples were collected ramdomly with sum of 6-10 members in each sub-cluster. Lansat TM satelite senses of 1996 and 2006 were used as the data sources of landuse. The Geographical Information System was used to analyze the satellite senses and digital maps spatially, and then the analytical descriptive technique involved Ordinary Least Square (OLS) and Seemingly Unrelated Regression (SUR), and also the valuation methods were used to analyze those collected data. Research results showed that (1) the built areas increased but the agricultural lands areas decreased as the time functions and there are variations among the zones, (2) the direction of landuse changing among agricultural lands were reversible and tended dominantly to the ZJRR, but the changing from agricultural lands to buildings were irreversible and tended dominantly to the ZDR, (3) the changing from agricultural lands to building had characteristics of (a) increased as the time function and reached the highest on the ZLRR, (b) the highest was taken placed from perennially crops lands, followed by from opened lands, and the smallest was from annulay crops lands, (c) supported by the factors of: increased land price, length of roads, built areas, increased population density, occourances of growth center, but inhibited by the agricultural land owning area, (d) created impacts to: lost of food production, lost of agricultural jobs opportunities, and lost of total economic values of multifunctionally of agricultural lands, and in these cases the losts from the annually crops lands were much bigger than from the perennially crops lands, (4) based on the communities perceptions about the impacts of the agricultural lands conversion could be stated that: (a) the prospect of farming sustainability was decreased as the conversion increased, (b) farmers' ability to sustain farming was decreased to the ZDRR direction, (c) Willingness to Accept (WTA) positively influenced by farming income, age, their knowledge about the multifunctionally of agricultural lands, family dependency ratio, but negatively influenced by nonfarming income, agricultural lands owning area, and zone (ZJRR), (d) public awareness of sustainable farming increased to the ZDRR direction, (e) Willingness to Pay (WTP) were positively influenced by household income, age, their knowledge about the multifunction of agricultural lands, but negatively influenced by the distance of settlement to the agricultural lands and zone (ZJRR), (f) there were decreasing of wellwater quantities, wellwater qualities, air quality, safety, amenity, sum of farmer, sum of agricultural jobs opportunities, and the prospects of farming sustainability, there were increasing noisy, flooded, garbages, land tax, nonfarming jobs opportunities, and land price.
