Space Adequacy Analysis Based on Population Pressure National park Area (Case Study : Putri Betung Sub District, Gayo Lues, Aceh)

The land requirement for Putri Betung Sub District in Gunung Leuser National Park (GLNP) area kept increasing along with the population growth. The population density in the Putri Betung Sub-district was driven by the need for cultivation and residential area along the GLNP conservation boundary. This study aims to analyze the space adequacy for Putri Betung Sub-District in the GLNP area based on the population pressure prediction for 20 years. The research method was conducted by field survey using remote sensing, interviewed the residents, and analyzed the population pressure index using the Soemarwoto formula. The Population Pressure Index (PPI) for the cultivation area was determined from 13 villages in Putri Betung Subdistrict and shows that 12 villages had a PPI 1 value (population pressure was over the land carrying capacity limits). Only one village had PPI 1 (population pressure less than the land carrying capacity. Based on data surveys obtained, the cultivation area set in the Putri Betung area was no longer sufficient for population, resulting from the expansion in the GLNP area of 4,776.97 ha. Meanwhile, predictive analysis on space adequacy for people living decently in Putri Betung Sub District for 20 upcoming years is 6117.15 ha. In conclusion, 12 out of 13 villages in the Putri Betung SubDistrict have PPI 1 value, which is inversely proportional to the land carrying capacity. The PPI values could result in other pressures on the ecology and biodiversity conservation in National Park. It is suggested that the government need to surpass the pressure by making new policy on people’s resettlement, expanding the cultivation area, or shifting people's livelihoods

Analysis of land carrying capacity and production factors of cocoa (Theobroma cacao L.) in Banggai Regency

This study aimed to determine the carrying capacity of land and production factors in the development of cocoa production in the Banggai Regency of Central Sulawesi. This research was conducted in 23 sub-districts of the Banggai Regency. Determination of respondents using cluster sampling method or grouping based on area or population location with 114 cocoa farmers. The research data were obtained from primary data, i.e., interviews, questionnaires. In contrast, secondary data were obtained from the Central Statistics Agency, the Banggai Regency Agriculture Office, and the Center for Research and Development on Agricultural Land Resources. The variables analyzed include regional economics (used LQ and SSA), land carrying capacity (DDL), and the production factors were land area (X1), number of workers (X2), fertilizer costs (X3), and pesticide costs (X4). Thus, this study indicated the direction of land allocation based on the regional economy, land carrying capacity, and cocoa production factors. Overall, cocoa plants could be developed in the Banggai Regency with an area of 419,236.9 hectares. However, there was a need for sound land use data management and intensive cocoa cultivation assistance to increase comparative and competitive human resources and improve the economy for the welfare of the cocoa farming community in the Banggai Regency.

Integrated Assessment of Urban Land Carrying Capacity (ULCC) for Reducing Earthquake Risk Risaster in Palu City

The land is a natural resource that has limitations to accommodate human activities. Rapid urban population growth, continuous expansion of urban scale, rapid socioeconomic development, and increased pressure on land resources between residents and urban land are monumental contradictions when urban planning does not match land carrying capacity. Assessing urban land carrying capacity is very important to evaluate and obtain an overview of the land capability level by classifying its capacity to be designed according to the area function; to get an overview of the potential and constraints of each land capability class, and to serve as a basis for future regional development. This research was conducted in Palu City, a national urban area in Indonesia. It has limited regional development because it is an area prone to high earthquake disasters. Developing the area requires assessing the land's carrying capacity, especially to minimize the risk of earthquake hazards. The assessment involves three stages of analysis, namely Mapping Earthquake-Prone Areas with Mapping of Earthquake-Prone Areas with seismic micro-zonation; Land Capability Assessment; and Comparative Analysis of Land Capability and City Planning of Palu 2030. This study's results indicate that 74.56% of Palu City is an earthquake-prone area, dominated by land capability classes type A to B, namely low to very low land capability classes (55.42%). Thus, there are physical limitations in urban development. However, suppose it is integrated with the spatial plan of Palu City until 2030. In that case, most (56.07%) are already in accordance with the carrying capacity of their land, especially in protected areas. However, land development still does not comply with their carrying capacity (35%) in cultivation areas with earthquakes. High and covering an area of 24% of the total area of Palu City requires special attention in the development of its area going forward. The requirement that land use plans that do not comply with their carrying capacity must be strictly controlled, especially in high disaster-prone areas.

Determination of the location of dragon fruit agrotourism development in Bangorejo Sub-district, Banyuwangi based on agrotourism development factors and land carrying capacity

Bangorejo Sub-district has abundant dragon fruit potential and can be developed into an agrotourism area. However, there are still problems including the drop in the price of dragon fruit when the main harvest arrives, the lack of added value of dragon fruit, and problems related to the land carrying capacity in which Bangorejo Sub-district contains expansive soil, namely land that is expanding and shrinking. This research was conducted to determine the location of dragon fruit agrotourism development in Bangorejo Sub-district, Banyuwangi based on the land carrying capacity. The methods used were the content analysis method for the first objective, namely identifying the factors that influence the development of dragon fruit agrotourism in Bangorejo Sub-district and scalogram analysis as well as the overlay for the second objective, namely identifying prospective agrotourism locations for agrotourism development in Bangorejo Sub-district based on agrotourism development factors and land carrying capacity. The results of this research found that the suitable villages for the dragon fruit agrotourism development includes Sukorejo, Ringintelu, Sambirejo, Sambimulyo, Temurejo, and Kebondalem Villages with the widest suitable land is at Kebondalem Village.

The land carrying capacity and environmental risk assessment of livestock and poultry breeding considering crop planting

At present, the contradiction between survival and ecology necessitates the integration of crop planting, chemical fertilizer application and livestock and poultry breeding. Reasonably integrated crop-livestock systems (ICLSs) have become an important part of regional ecological and agricultural development. In this study, the relationship between manure nutrient demands for crops and manure nutrient supply from livestock is considered based on the balance of ICLSs in Jiangxi Province, China. The land carrying capacity index and potential of livestock breeding under uncoordinated systems are further discussed. The study also addresses water environmental risk due to surplus nutrients by integrating a traditional land carrying capacity framework and hydrological model. The results show that phosphorus absorption in land areas is the main limiting factor for the development of the livestock and poultry industries. In addition, manure nutrient demand exceeded supply in most districts, while the unbalanced regions with nutrient pollution are located in the upper and middle reaches of the Ganjiang basin. In addition, expanding the crop demand for manure or increasing the manure collection rate will help reduce environmental harm; however, attention should be paid to the risk of excessive manure returns. Additional livestock manure can be transferred to regions with developed crop planting systems. This study supports more harmonious and common ICLSs construction.

Study on Relative Carrying Capacity of Land Resources and Its Zoning in 31 Provinces of China

Land carrying capacity is an important indicator to quantitatively assess and judge the extents of sustainable economic developing and coexistent harmonizing between human and nature. The significance of land carrying capacity has been highlighted recently by the Sustainable Development Goals (SDGs) of the United Nations, which set clear requirements for arable, construction, and ecological lands. Theories and models of land carrying capacity, however, are suffering from the interference of artificial parameter setting and poor applicability. This paper attempts to overcome these limitations and propose a single factor assessment of the carrying capacity of cultivated land, construction land, and ecological land in terms of the relative carrying capacity from the perspective of a single factor assessment. Through mutual comparison, we found that the deviation caused by simulated parameter setting has been eliminated, and the relative status of each province and/or region in China has been obtained, which could provide a reference for the management and utilization of land resources. We argue that China can achieve basic self-sufficiency in both space capacity and food production without placing pressure on the global sustainable development. The results also indicate that carrying capacity state of the advanced development areas such as the eastern coastal region is relatively poor, while the carrying capacity state of the western region is relatively good.
