“…The built-up land cover also experienced a significant increase in the area due to large changes (>40,000 ha) contributed by changes in non-field agricultural land cover and rice fields. The built-up land area increases due to space requirements, population growth, economic growth, and the fulfilment of facilities to support human activities [17] [18] [19]. The level of development of districts/cities in Central Java Province in 2014 and 2019 based on the regional development index is presented in Figure 4.…”

The high population of Central Java Province has become a factor triggering the dynamics of land cover change and regional development. Uncontrolled urban expansion and development threatens sustainability. This study aims to identify the types and patterns of land cover change, the level of regional development, the index of sustainable development in environmental, social, and economic dimensions, and the typology of regencies/cities based on the index of sustainable development. This research was conducted in Central Java Province from January to April 2023 using land cover data, village potential data, provincial statistics, and administrative maps. Land-cover changes were identified using overlay analysis in QGIS. The level of regional development was determined using the scalogram. The index of sustainable development was constructed using factor analysis, while the regional typology was identified using cluster analysis. The results showed a dynamic change in forest cover, with a significant decrease from approximately 1 million hectares to 550,000 ha from 2014 to 2019. Agricultural land and built-up areas increased by 312,000 ha and 164,000 ha, respectively. A scalogram analysis indicated an improvement in the regional development index. Sustainability analysis reveals that the sustainability index in the economic dimension is lower than that in the social and environmental dimensions. The cluster analysis indexes that approximately 60.31% of the areas had a low sustainability index. All urban areas have a high sustainability index in the economic and social dimensions, otherwise in the environmental dimension.

“…There are lands incompatible for cultivation including timber plantation, plantation, dryland agriculture, and mixed dryland agriculture. Ramadhan et al (2016) claimed that land situated on >40% of slope are vulnerable to erosion and landslide. Yi et al, (2010) who did research in Enshi, China declared that human activities in using land for dryland agricultural cultivation and farms play important role in accelerating soil weathering which resulted in slope instability.…”

“…The changes of forest areas into agricultural lands also cause damages in the ecosystems at watershed level as considerable areas in the landscape become incompatible with its capability, affecting its carrying capacity and quality (Sinukaban 2007;Harjianto et al 2016). Ramadhan et al (2016) reported that incompatibility in terms of the use of an area could cause landslide problems. Large changes in land uses without taking into account natural resources sustainability and environmental functions would cause land degradation which may trigger erosion, sedimentation, flood, and landslide in watershed ecosystems.…”

Abstract. Sopian A, Hardwinarto S, Aipassa MI, Sumaryono. 2019. Gap analysis of land availability and land needs to identify potential development of agricultural lands in Santan watersheds, East Kalimantan, Indonesia. Biodiversitas 20: 1097-1105. Pressures caused by high population growth in various places increase the needs for lands. The aims of this research are to determine the availability and needs of agricultural lands in Santan 1 and Santan 2 watersheds, East Kalimantan, Indonesia as well as to classify land capability which are key aspects in managing land resources. Land availability was determined based on the local actual total production of all commodities, such as agriculture, plantation, and livestock at the sub-district level. Land needs were determined based on the land area required for decent life needs per resident. While land capability was determined using weighting analysis of the limiting factors. Results of this study show that land availability on Santan 1 and Santan 2 watersheds is inadequate to fulfill the needs of inhabitants for agricultural lands. There are 19,053 hectares of lands currently available for agriculture, while there are 56,969 hectares of lands required for agriculture, implying a deficit of 37,916 ha of land. Analysis on land capability shows that lands with eutropepts and tropudults soil with total extent of 16,650,9 hectares are potential to be developed for dryland agriculture, such as seasonal crops, while tropohemist soil is suitable for farmland development, such as lowland rice. The spatial plans in Santan 1 and Santan 2 watersheds do not have adequate lands with agricultural capability since the cultivation areas are situated in VI and VII class with limiting factor of slope and erosion. We find there is undeveloped land in the form of bushes with an extent of 12,989,3 hectares in Santan 1 watershed and 7,055.54 hectares in Santan 2 watershed as potential lands to be developed for dryland agriculture. The results of this study suggest that when establishing neighborhood and hamlet should refer to soil characteristics with certain land capability and cultivation activities not to be done on lands with slopes of >15%.
