Recent innovations in land capability classification for sustainable development: a brief overview.

Land is a finite resource that must be managed wisely to ensure its sustainability. Consequently, land evaluation has become essential. Identifying and utilizing productive capacity of land efficiently and profitably is crucial; otherwise, resource degradation can severely impact natural ecosystems and food production. Over the years, various methodologies have been employed to assess land resources, and one such method is the Land Capability Classification (LCC). LCC is a widely used and fundamental approach to land-use planning, traditionally assessing land based on its intrinsic qualities and climate. This study aims to highlight new approaches and developments in land evaluation techniques. It provides a brief overview of recent technological and scientific advancements integrated into land evaluation. The findings suggest that LCC alone is inadequate for precise land assessment, emphasizing the need to integrate new technologies. Remote Sensing (RS) and Geographic Information System (GIS) technologies are becoming increasingly significant. Integrating various software, decision-making systems, and mathematical models can also enhance the accuracy of land assessment results. The continuous advancement of GIS and remote sensing technologies is paving the way for new tools to facilitate natural resource mapping, appraisal, surveillance, and management. Utilizing these technologies for future projections will be highly beneficial in accurately assessing the long-term impacts of current land management practices.

A method to map land use impacts on microclimate regulation supply in urban environments

Land use impacts land surface temperature (LST), especially in urban areas where anthropogenic materials have a high capacity to store energy. Nevertheless, cities have many other land uses (e.g., forests, lawns) that can reduce LST and contribute to high microclimate regulation. In this work, we develop a method to map land use impacts on microclimate regulation supply using an Unmanned Aerial Vehicle (UAV). A detailed methodology was developed for 1) UAV's mission planning, 2) field data collection for method validation, 3) RGB and thermal mission reconstruction, 4) land use classification, 5) data extraction and 6) spatial and statistical analysis. The method developed can be beneficial to local authorities and transferable to other realms. It will allow us to understand the impacts of different land uses on microclimate regulation. For this, an area with heterogeneous land uses was used as a test site.• A novel methodology was created to map land use impacts on microclimate regulation supply in urban areas;• High-resolution UAV RGB and thermal imagery for land-use classification and surface temperature analysis;• The method can help understand the capacity of the different land uses on microclimate regulation;

KAJIAN RENCANA TATA RUANG WILAYAH BERDASARKAN RISIKO BENCANA GEMPA BUMI DI KOTA JAYAPURA

A study has been conducted on the typology of earthquake disaster-prone areas in the city of Jayapura and the suitability of Regional Spatial Planning (RTRW) for land use capacity in the city of Jayapura. The study onearthquake disaster-prone area typology aims to determine the distribution of stability levels of the area againstthe risk of earthquakes. This study employs a weighting matrix method for area stability based on the Minister ofPublic Works Regulation No. 21 of 2007 concerning Guidelines for Spatial Planning of Volcanic Eruption andEarthquake-Prone Areas (Department of Public Works, 2007). The research results indicate that the final score forthe city of Jayapura is between 30 - 45, which falls into all stability categories: stable and less stable. Thepercentage of area for each category is 97.81% for Stable Type A, 1.91% for Stable Type B, and 0.28% for LessStable Type C. The typology of earthquake disaster-prone areas in Jayapura based on stability scores falls intocategories A, B, and C. The study on the suitability of the Regional Spatial Planning (RTRW) for 2013-2033 with the land usecapacity in Jayapura was assessed by scoring data on land capacity and land use, followed by an overlay analysis.This resulted in a land capacity suitable for development of 57,039.39 hectares, or about 60.48% of the study area,while approximately 37,272.96 hectares, or around 39.52%, were deemed unsuitable.

Benefit evaluation of sloping land conversion program in the upper reaches of the Yellow River

This study used forestry statistical data and field survey data from 2000 to 2018 to analyze the ecological restoration effect of the returning farmland to forest project in the upper reaches of the Yellow River, considering four perspectives, namely, project construction goals, ecosystem quality, ecosystem service functions, and ecological restoration driving factors. One-way ANOVA and logit regression analysis methods were used for comparison. The results show that the implementation of the Grain for Green Project has reduced the carrying capacity of rural land, effectively curbed the continuous deterioration of the ecological environment, and protected and benefited the forest ecosystem. (1) Initiatives of the return farmland to forest project have achieved the expected goals, and the forest coverage rate has increased significantly from 5.26 % (in 2000) to 15.63 % (in 2019); the proportion of primary, secondary, and tertiary industries related to forestry has reached a reasonable level, and the economic benefits thereof continue to improve. (2) Indicators such as total forest and grass vegetation coverage, vegetation net primary productivity, and forest and grass health index reflect that the functional quality of the regional forest and grass ecosystem is gradually improving. (3) The ecosystem service function of the project region has improved considerably, and the ecological benefits are significant. (4) In terms of the contribution value of the driving forces for this ecological restoration project, they can be ranked as follows: government investment > reducing land carrying capacity > policy of returning farmland to forest > government management > hydrological factors > meteorological factors. (5) After the implementation of the Grain for Green Project, farmers' income has increased significantly, but the changes in livelihood capital income are not synchronized. As the ecological environment in the Grain for Green project areas gradually improved from deterioration, the natural capital and social capital of farmers' livelihood capital decreased significantly, while the physical capital and financial capital increased significantly, with no significant change in human capital. Farmers' satisfaction with the Grain for Green Project is as follows: natural capital has a significant negative impact, while financial capital and social capital have significant positive impacts, and there are no significant changes in physical capital and human capital. Finally, the consistency test results show that the fit is as high as 95 %, and the accuracy exceeds 90 %. Notably, the implementation of the Grain for Green Project has played a pivotal role in ecological restoration and contributed greatly to ecological benefits. These achievements provide a scientific basis and theoretical support for the country to formulate relevant policies for forestry projects, which holds great significance for the country in addressing the contradiction between economic and social development and ecological protection.

Quantifying and Zoning Ecological Compensation for Cultivated Land in Intensive Agricultural Areas: A Case Study in Henan Province, China

Cultivated land ecological compensation (CLEC) is an important way to solve regional development imbalance and cultivated land problems, and the scientific quantification of the ecological value of cultivated land is the key to CLEC. This study quantified the total amount and urgency of CLEC in China’s main grain-producing region using the cropland ecological footprint (EF) and ecosystem service value (ESV) methods. Furthermore, this study analyzed the comprehensive zoning of CLEC considering natural and economic development. The results showed that the spatial distribution of EFs and the ecological carrying capacity of cultivated land in Henan Province are similar, presenting the spatial characteristics of being high in the southeast and low in the northwest; the cultivated land in most of the counties and districts is in a state of ecological surplus, and the cultivated land resources are sufficient to support their own consumption needs. Henan Province as a whole is an ecologically compensated region, with a compensation amount of CNY 1.39 billion, and the total amount of compensation is in a positive value of 94.94%. The Southwest Yu and North Yu economic zone of Henan are the areas of high and low values of cultivated land compensation. The priority compensation region is the most extensive and widely distributed type in the five regions of Henan Province, accounting for 55% of the counties and districts. The degree of compensation is most urgent in the Huanghuai, Southwest Yu, and North Yu economic zones. This study’s findings provide new ideas for the development of differentiated ecological compensation policies, and provide references for the participation of multiple market participants and the diversification of compensation forms.

A life cycle-based comparison study of sludge recycling technology incorporating subjective and objective evaluations

Inadequate land capacity and low sludge recycling rates have become a major global environmental challenge. Low organic sludge content and inadequate waste management policy mean that there is an urgent need to improve sludge solutions in China, which has the world's largest WWT capacity. Decision-makers face difficulties in selecting sustainable sludge-to-resource technologies given the existence of multiple social, environmental and economic objectives, and also in optimizing the allocation of sludge between different available technologies. In this paper we used a combined analytic hierarchic process (AHP) and entropy weight (EW) method to evaluate four recycling technologies: aerobic composting (AC), dry-incineration (DI), hydrothermal carbonization (HTC) and pyrolysis (PY), in terms of five economic, environmental and land resource indicators. The results showed that human toxicity was viewed as the most important indicator, while economic value of sludge product was the least important. HTC had the best overall performance of the evaluated technologies while PY was the least attractive. However, all four sludge recycling technologies showed greater potential for reducing carbon emissions and human toxicity than landfilling when sludge dewatering was included. Sensitivity analysis showed that adjustments to AHP weights only had a limited impact on the technical ranking. Finally, the result was further verified by a particle swarm optimization algorithm. Considering capacity constraints, the optimal proportion of the four technologies was found to be 44.9%, 42.7%, 0 and 12.4% for HTC, DI, PY and AC respectively. The paper demonstrates the effectiveness of combining subjective and objective methods to evaluate multiple indicators, providing decision-makers with a practical analysis framework for waste technology selection.

Land Cover Simulation and Carbon Storage Assessment in Daqing City based on FLUS-InVEST Model

Considering Daqing City as the research area, the impact of land cover change on carbon storage in the future was discussed, and the hot spots of carbon sequestration capacity were identified. The future land use simulation （FLUS） model was used to simulate the land cover pattern of a natural succession scenario, ecological protection scenario, urban development scenario, and comprehensive development scenario in 2030, and the integrated valuation of ecosystem services and trade-offs （InVEST） model was combined to estimate carbon storage in 2010, 2020, and 2030. Finally, the hot spot analysis tool was used to identify the cold hot spots of carbon sequestration capacity. The results showed the following： ① From 2010 to 2020, the area of cultivated land, water, and artificial surface increased, whereas the area of other land cover types decreased, and the total carbon storage decreased by 8.6×105 t. ② The land cover change of the natural succession scenario and urban development scenario in 2030 was similar to that of 2010-2020, with carbon storage decreasing by 1.16×106 t and 1.20×106 t, respectively. The carbon storage of the comprehensive development scenario decreased by 1.00×106 t compared with that in 2020, and carbon storage of the ecological protection scenario was 5.677 7×108 t, which increased by 2.53×106 t compared with that in 2020. ③ The conversion of grassland and wetland to cultivated land was the main cause of carbon storage loss, and the main contributor of carbon storage in the ecological protection scenarios was wetland. ④ The hot spots of carbon sequestration capacity were mainly located in the wetland area, and the cold spots were mainly distributed in the central part of Daqing City. The carbon sequestration capacity of cultivated land was not significant. According to the research results, to realize the urban transformation of Daqing City, we should insist on returning farmland to forest and grass, increase the intensity of returning moisture, improve the utilization rate of urban land, and increase green infrastructure in the main urban area.

Оптимизация пастбищной нагрузки на степные экосистемы аридной территории Ставропольского края

Abstract. The article considers the issues of rational use of grass of steppe phytocenoses in their pasture use; the correspondence of pasture capacity and the number of grazed livestock. The purpose of the study is to assess the current state of steppe communities used as pasture lands for grazing existing livestock of large and small cattle and to propose ways to optimize pasture livestock breeding in the arid territory of the Stavropol Territory. Methods. A statistical analysis of the number of cattle and small cattle in the study area was carried out. The expeditionary study of natural herbages was carried out in 2021–2023 on accounting sites (100 m2) according to the requirements of methods generally accepted in phytocenology. The results of the study. Statistical analysis showed that by the beginning of 2000, the number of sheep in the territory under consideration had decreased by 2.6 times, and cattle by 1.6 times. In subsequent years, with the gradual recovery of the livestock industry from the crisis, a steady increase in the number of small and large cattle was noted in this zone to 1306.1 and 74.8 thousand heads, respectively. It was revealed that the vegetation of natural lands used in pasture farming in the arid zone of the Stavropol Territory is secondary, stunted and monotonous in terms of flora composition and plant associations. The capacity of the pasture lands does not correspond to the feed needs of the grazed livestock. At the moment, the shortage of pasture feed is 323.7 thousand tons of feed units. On such pasture lands, animals do not receive food in sufficient quantities. It is recommended to optimize pasture management by limiting the pasture load and bringing the number of grazed livestock in line with the feed capacity of pasture lands. This will help to provide the existing livestock with food that meets their regulatory needs. Scientific novelty. New data have been obtained on the current state of steppe communities in the arid territory of the Stavropol Territory and the correspondence of the number of grazed livestock to the pasture capacity.

Étude capacité théranostique 2023–2024 – Modélisation sur la base de la RIV-PSMA. Radiothérapie interne vectorisée (RIV), une approche théranostique à laquelle le patient doit avoir accès. Partie II : analyse approfondie

This in-depth analysis highlights the issues and perspectives regarding the deployment and optimization of vectorized internal radiotherapy (VIR), based on the VIR-PSMA model, which is the first theranostic modality that changes the scale of clinical management in nuclear medicine. It made it possible to confirm a characterization of health establishments based on their experience and their ability to integrate this new treatment modality into their care offering. Here are 8 key points and recommendations highlighted in the following pages: 1. Current and future reception capacity: “experienced” and “initiated” establishments have the greatest short-term reception capacity, while “medium-term future” and “long-term future” establishments will come, in the medium and long term respectively, strengthen the provision of care. They will be able to strengthen the healthcare offer and the territorial network if the award of a B rating allows them to do so. 2. Discrepancy between capacity and need: a gap is already observed between the number of patients who can be treated and the real needs of patients eligible for VIR-PSMA, even though capacity projections are voluntarily restricted to “experienced” and “initiated” services only (the “future” services in the medium and long term are not to date uniform in obtaining the necessary authorizations). This gap between capacity and need can be considered initially by optimizing the use of existing resources (in particular thanks to available land capacity), which remains mainly limited by the shortage of professionals. Secondly, the granting of authorizations to “future” services will make it possible to complete the system, and in particular to promote the regional distribution of care provision which shows disparities that could be sources of inequitable access to care in France. 3. Clinical pathway and harmonization of practices: the clinical pathway for patients benefiting from a VIR requires harmonization of practices and the making of recommendations by the SFMN (from the assessment of eligibility to post-dose monitoring, including the organization of treatments and the reception of patients). 4. Training and recruitment needs: the anticipated growth in demand for VIR requires strengthening teams through the recruitment of all staff involved in the patient's journey, as well as the creation of cooperation protocols between all health professionals by strengthening the initial and continuing training of all professionals involved. 5. Investments and adaptation of infrastructure: significant investments in specialized infrastructure and in the upgrading of “up-and-coming” establishments are necessary to support the increase in VIR-related activity. 6. Define a valuation model allowing these care activities to be sustained while meeting specific constraints in terms of operation, infrastructure, and regulations. 7. Role of regional health agencies (ARS): the ARS play a crucial role in coordinating the deployment of the VIR, requiring adaptation of the offer to local needs and a coherent national policy to face the challenges, particularly in the awarding of B grades, but also by ensuring that the teams of professionals are sufficient and trained and that the service meets logistical and security requirements. 8. Short, medium and long term strategies: to respond to the anticipated saturation of reception capacities, strategic actions are necessary in the short-term (less than 2 years), in the medium-term (less than 5 years), and long-term (more than 5 years), including the structuring of the organization, the expansion of recruitment, the harmonization of practices, and the strengthening of reception capacities.

Spatiotemporal Variation Characteristics and Driving Factors of Cultivated Land NPP in the Shandong Area Around the Bohai Sea

The Bohai Rim Plain is an important grain-producing area in China. The cultivated land resources have great potential for production, but there are many influencing factors. Understanding the spatiotemporal change characteristics and driving factors of the net primary productivity （NPP） of cultivated land vegetation in this region is of great significance to improve the regional cultivated land production conditions, excavate and enhance the production capacity of cultivated land, and ensure national food security. In this study, Theil-Sen Median trend analysis, Mann-Kendall significance test, Hurst index, and other methods were used to explore the spatiotemporal change characteristics, stability, and sustainability of regional cultivated land NPP. The influence of driving factors on the spatial heterogeneity of cultivated land NPP was analyzed by using optical parameters-based geographical detectors. The results showed that： ① From 2001 to 2019, due to the expansion of construction land during industrialization and urbanization, the cumulative decrease in the area of cultivated land in the Shandong area around the Bohai Sea was 2 004.51 km2. ② During the selected research period, the interannual variation of average cultivated land NPP showed a fluctuating and increasing trend. In terms of spatial distribution, the NPP of cultivated land was bounded by the Dongying District, with the spatial heterogeneity in the north being significantly lower than that in the south. ③ The area with increasing NPP of cultivated land accounted for 88.06% of the total area of cultivated land, mainly with low and medium fluctuations. The NPP of cultivated land will maintain an overall sustained trend of increase across the region in the future. ④ The average annual relative humidity study area had the strongest explanatory power for the spatial variability of NPP in cropland, with a q-value of 0.26, followed by surface soil salinity and subsoil salinity, with q-values greater than 0.2. The interactions between the different drivers all showed either nonlinear enhancement or bifactorial enhancement. The results of this study will help to reveal the characteristics of the changes in cultivated land production capacity and its driving forces in the Bohai Sea region and also provide a theoretical basis for the ecological protection and sustainable development of the region.

And for a period of 30 years, 2032, 2042, and 2052, Mandiangin Koto Selayan sub-district and Aur Birugo Tigobaleh sub district still have a surplus while Guguk Panjang sub-district is still in deficit.

ANALISIS DAYA DUKUNG LAHAN PERTANIAN SEBAGAI UPAYA MENDUKUNG KETERSEDIAAN PANGAN DI KAWASAN SLEMAN TENGAH

The Central Sleman area is a peri-urban area directly adjacent to Yogyakarta, making land conversion increasingly prevalent and unavoidable. In comparison, the Central Sleman area has a role as one of the food barns due to fertile land conditions and is suitable for agriculture. Intensive conversion of agricultural land to non-agricultural land will result in the loss of productive agricultural land, resulting in decreased rice production. This will result in high rice imports and reduced employment in the agricultural sector. This research aims to analyze the development of agricultural land use, its projection, and the carrying capacity of agricultural land in the Central Sleman Region. The calculation of the agricultural land carrying capacity is based on Odum, Howard, and Issard. The results showed that the Central Sleman Area has a decreasing rate of change in the agricultural land area every year in Kapanewon. The calculation results of agricultural land's carrying capacity show that in 2020, land's carrying capacity exceeded 0.83. The results of the projection calculation in 2024 found that 4 out of 5 Kapanewon in the Central Sleman Region cannot achieve food self-sufficiency. Therefore, efforts are needed to increase the carrying capacity of agricultural land, mainly through increasing the productivity of food crops and protecting agricultural land from land conversion.

South Tapanuli District has quite potential in developing beef cattle by maximizing the potential of land with various types of plantation and agricultural plants as a source of animal feed. The objectives to be achieved in this research are to analyze the availability of feed based on plantation crops and food crops that support beef cattle feed sources, analyze variables in beef cattle development in influencing the number of beef cattle populations, and analyze strategic factors that influence the success of developing beef cattle and formulating strategies to increase beef cattle production in South Tapanuli District. Multiple linear regression analysis was used to examine the data. The study's findings demonstrate the abundance of potential carrying capacity of the region's land, with plantation area having the capacity to support 1,420 beef cattle annually and agricultural land having the capacity to support 14,508 cattle annually.

Status of Land Carrying Capacity for Agricultural and Environmental Sustainability in the Nusa Penida Tourism Area

Land resources are very important in supporting tourism activities. As a developing tourism area, Nusa Penida requires sufficient land resources. The increasing population and tourists have triggered new activities affecting land use patterns, negatively impacting land availability and agricultural sustainability. This study aims to calculate the availability, needs, and status of land-carrying capacity to support the sustainability of agriculture in the Nusa Penida Tourism Area until 2028. The research method uses a quantitative approach by collecting primary data obtained directly in the field, secondary data originating from previous research, and data originating from official sources. The result of the calculation of land requirements based on the ecological footprint is the number of inhabitants multiplied by the ecological footprint (gha/capita); the land requirement for 2020 is 49,849 people multiplied by 0.36958702, which is 17,724.283 hectares, while the availability of land in Nusa Penida is 9,894 hectares. This shows that the carrying capacity of land in Nusa Penida has exceeded the threshold or a deficit of 7,830.283 hectares. The area of land in Nusa Penida reaches 20,284 hectares. In contrast, the availability of land in Nusa Penida is based on calculations using the actual production of each type of commodity and the price of rice at the producer level, the unit price of each commodity at the producer level, and the productivity of rice in Nusa Penida is only 9,894 hectares. The projection of land needs until 2028 is 24,640 hectares, so the land carrying capacity in Nusa Penida is a deficit. The results of the calculation of land requirements based on the ecological footprint are 14,746.283 hectares, while the availability of land in Nusa Penida is 9,894 hectares. This shows that the land carrying capacity in Nusa Penida has a deficit of 12,374.283 hectares.

Evaluating dynamic soil quality by the soil management assessment framework (SMAF) in the watershed scale in a semi-arid Mediterranean ecosystem in Turkey

Soil is an indispensable and important natural resource and it is necessary to manage and monitor soil quality with appropriate methods in order to ensure the sustainability of the soil. The aim of this study is to determine the current state of soil quality in different land uses where soil functions change. This study was carried out in the Karasu river watershed with an area of 19,178 ha where Entisols soil order is dominant, located Andırın, Kahramanmaraş. The Soil Management Assessment Framework (SMAF) method and Principal Component Analysis (PCA) was used to assess the dynamic soil quality in watershed scale. In the evaluation of soil quality, random samples were taken from a total of 360 topsoil layers (0−30) according to land use and physiography. Soil indicators such as bulk density, aggregate stability, total organic carbon, pH, electrical conductivity, available phosphorus (P), potassium (K), available water amount and water-filled pore volume were selected to create the minimum data set (MDS). The results showed that the productivity, environmental protection, waste recycling quality scores and general soil quality index of forest lands are higher than agricultural lands. According to expert opinion, general soil quality scores were found to be 0.86 in forest land, 0.78 in crop land and 0.83 in grassland, while in PCA, general soil quality scores were calculated as 0.85 in forest land, 0.79 in crop land and 0.78 in grassland. Contribution level of soil functions to management targets was observed in water relations function the most. The contribution levels of the water relations function to the productivity, environmental protection and waste recycling management targets are 0.38, 0.32 and 0.34 in forest lands, 0.42, 0.33 and 0.35 in croplands, respectively; It was showed that 0.40, 0.33 and 0.36 in grasslands. Contribution rates of productivity, environmental protection and waste recycling management targets to soil quality were 30%, 37% and 33%, respectively, in forest lands; 29%, 37% and 34% in crop lands; It has been determined as 30%, 36% and 34% in the grasslands. Negative effects such as heavy rainfall in the watershed, wrong agricultural practices (excessive fertilization and irrigation, improper tillage, and crop selection, etc.) and excessive grazing have led to soil degradation and erosion, reducing the soil function capacity of agricultural lands and meadows. In order to increase the functional capacity of the soil, a soil management approach aimed at protection, improvement and sustainability must be adopted and implemented.

This aims of this study 1) to analyze the carrying capacity of agricultural land in supporting food security in Mataram City. 2) to determine the availability and need for staple food (rice) in Mataram City. The research method used quantitative descriptive methods using secondary data from the Central Statistics Agency of City of Mataram and other related agencies in Mataram City in 2023. Data was analysed using land carrying capacity analysis and analysis of the availability and demand for rice in the City of Mataram. The results of the research showed that 1) the carrying capacity of agricultural land in the City of Mataram is 0.0231 or less than 1, meaning that the need for rice in the City of Mataram has not been able to be met from the existing agricultural land area and the current rice production, 2) The availability of rice in the City Mataram in 2023 is 13,510.83 tonnes, while the demand for rice is 67,980.76 tonnes, resulting in a shortage (deficit) of rice demand of 54,469.93 tonnes or a deficit in rice availability of 400%.

Agrivoltaic systems for sustainable energy and agriculture integration in Turkey

In recent years, the use of solar photovoltaic (PV) energy, which is one of the leading renewable energy sources, has become increasingly widespread around the world due to its numerous advantages. However, PV-based electricity generation necessitates a large amount of land. Agrivoltaic (AV) systems, an innovative approach to combining agricultural and electricity production in the same area through solar modules positioned several meters above the surface of the ground, are growing rapidly in renewable energy and farming communities. This study explores Turkey's solar power generation and agricultural activities, combining crop cultivation and electricity generation for sustainable development on the same land. Furthermore, the AV potential for the most agriculture ten cities in different climate zones in Turkey is investigated using the PVsyst program. A list of the most commonly grown crops in the ten selected cities and the types of AV systems that can be employed with these crops is provided. The results show that AV systems present a great opportunity for the optimal integration of solar power generation with food production, especially for the cities of Konya, Kayseri, and Manisa, with the most ideal conditions for agricultural and solar power production. By combining the solar power potential of the country with the production capacity of arable lands, the increasing energy needs can be met and more efficient agricultural production can be provided. This study is expected to demonstrate that in specific regions of Turkey, AV farming will be suitable for certain crops.

Social Capital and Human Capital in Supporting Sustainable Aquaculture: The Case of Patuguran Village, Indonesia

Patuguran Village is one of the aquaculture center in Pasuruan Regency. Aquaculture that is carried out by the village community is able to improve the local economy. By implementing sustainable aquaculture, the development of aquaculture not only focuses on profit, but also reduces losses and other negative impacts on nature and society. However, the carrying capacity of pond land, availability of fish seeds, limited use of technology, along with limited assistance and training are problems faced by fish farmers in Patuguran Village. Social capital and human capital can be a strategy for aquaculture development by considering the ability of human resources. This study aimed to determine the influence of social capital and human capital in developing sustainable aquaculture in Patuguran Village, Rejoso District, Pasuruan Regency. The data collection method used a questionnaire aimed at 93 respondents and was analyzed with descriptive statistical analysis to identify the characteristics of social capital, human capital, and aquaculture that will be followed by SEM (Structural Equation Modeling). The result showed that the social capital, human capital, and aquaculture is in good condition. There is a positive and significant relationship between social capital and human capital towards sustainable aquaculture.

Livelihood, irrigation, and landslide: Unfolding the human-water-land nexus using an integrative framework

Irrigation-induced landslides occur globally and cause destructive consequences. Farmers’ dual roles as the cause and victim of irrigation-induced landslides call for systematic assessment of the nested human-water-land interactions to mitigate landslides. This study develops an analytical framework based on social-ecological system framework (SESF) and sustainable livelihood framework (SLF), which is applied to diagnose human-water-land interactions in the case of Heifangtai (HFT) in Loess Plateau, China. A three-tiered indicator system includes 68 indicators to explicitly assess the first- and second-tier variables in the integrative SESF-SLF. Multi-sourced data was collected, triangulated, and analyzed to unfold the interactions, dynamics, and evolutions in the regional SES and individual livelihood. The results show that the interactions between farmers’ livelihood strategies and the carrying capacity of regional land and water systems are the primary drivers shaping social-ecological relationships in HFT, followed by resource utilization and actors’ decision-making. Development opportunities are provided based on SES diagnosis, and methodological issues of framework construction and method and data integration are discussed. Integrating individual livelihood perspectives into SES provides a more nuanced solution to explain the specifics of resources utilized in livelihood strategies, which shows applicability and suitability in HFT and other similar cases of human-water-land interaction.
