The water resource shortage is a crucial factor in restraining the development of society and the economy in Xinjiang, where there is drought and little rain. The assessment of the water resources carrying capacity (WRCC) is a prerequisite for socioeconomic sustainable development in Xinjiang. In this paper, a convenient and effective model is established for assessing the WRCC under the influence of social welfare and water use efficiency. Meanwhile, a pedigree chart for WRCC is put forward. Then the developed approach is applied to investigate the sustainable utilization of water resources in Xinjiang. The results indicate that the WRCC of Xinjiang is not overloaded in 2018. The status of the WRCC is worse in northern Xinjiang than in southern Xinjiang, especially in Karamay, Shihezi, and Urumchi. The areas with potential water resource exploitation in Xinjiang are mainly located in the Yili Kazak Autonomous Prefecture and Altay Prefecture. The efficiency of agricultural water use is of vital importance to the WRCC in Xinjiang. The WRCC of Xinjiang can be improved by saving agricultural water, water recycling, and optimizing industrial structures. The maximum population carried by the water resources in Xinjiang is predicted to be 33.63 million and 35.80 million in 2035 and 2050, respectively. The assessment of the WRCC provides a valuable reference for the sustainable utilization of water resources in Xinjiang.

Unbalanced development is an urgent issue that needs to be resolved in the sustainable development strategy of Jiangsu Province, which inhibits Jiangsu’s industrial transformation and upgrading. A relative resource carrying capacity model is extended based on resource carrying capacity to analyze the resource carrying capacity of the different regions of Jiangsu Province. Three indicators of water resources, land resources, and energy resources are included in the natural resources. In social resources, factors of population quality are included in the analysis scope. Based on the improved model, this paper analyzes the relative resource carrying capacity of Jiangsu Province. The results show that: (1) under both traditional resource carrying capacity model and the improved model, Jiangsu Province has a surplus population; however, there is a certain difference between the result from two modules; (2) contributions of environmental resources, economic resources, and social resources to the comprehensive carrying capacity of resources is obviously higher than the contributions of natural resources; and (3) significant regional differences exist in relative resource carrying capacity within Jiangsu Province between the southern region and the middle region, in which the capacity is surplus to the population demand, and the northern region, in which the capacity is overloaded.

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.

The concept of driving force-state-response (DSR) framework was used to identify and develop the assessment model of water-land environment carrying capacity (WLECC) for a river basin. The river basin water-land management (RBWLM) decision support system was developed, based on the assessment model of WLECC, as a decision making tool. The Chung-Kang river basin, located in northern Taiwan, was used as a case study to generate a sustainable water-land management strategy. This strategy simultaneously derives the optimal solutions for land use management, water demand allocation, and water quality management. Furthermore, the sustainable WLECC can also be obtained. The WLECC can be used as the area-based indicator of sustainability to accurately measure the progress towards sustainable development for a river basin.

The assessment of ecological environment during the large-scale development of islands is a major topic in the study of current coastal islands. Choosing the appropriate assessment method to evaluate the suitability of carrying capacity of islands and making relevant suggestions are significant to the sustainable development of islands. Ecological footprint method is used to analyze the ecological carrying capacity of Pingtan Island (PI) from 2005 to 2016 for promoting the coordinated rational development and construction and ecological environment of the island. Although PI is in rapid urban development and construction, the island maintains secure and stable ecological conditions. PI is used as a research case to analyze the sustainable development of the ecological environment through the carrying capacity of the island ecosystem.

The paper presents an assessment of the acceptable tourist bathing load with regard to the physical, real, and effective carrying capacity of coastal beaches. In the case study of the Town of Mali Lošinj (Croatia), the paper scrutinises the carrying capacity of beaches categorised according to their basic characteristics and presents an analysis of beach capacity in the real conditions of the 2018 tourist season and in three hypothetical scenarios, two of which involve the application of recommendations for COVID-19 epidemiological measures. The basic hypothesis of the paper is that the real carrying capacity of beaches in the researched area under normal conditions is close to the upper load limits and that the carrying capacity of beaches will no longer be sufficient (vis-à-vis demand) when epidemiological recommendations are applied. The aim of this paper is to provide measurable bases for sustainable physical plans and development policies in tourism.

Sangalaki Island Nature Tourism Park (NTP) is one of the tourist destinations in Derawan. As a conservation area, tourism development in Sangalaki Island NTP must pay attention to the carrying capacity of the area. The purpose of this research is to calculate the carrying capacity in the NTP area of Sangalaki Island. The research was conducted in October 2021 through literature studies, field observations, and interviews. The calculation of the carrying capacity is carried out with the concept of Physical Carrying Capacity (PCC). The PCC of the area in Sangalaki Island NTP is 259 people/day with details of beach tourism 77 people, snorkeling 69 people, diving 44 people, tracking 13 people, and animal watching 57 people. The PCC data can be the basis for the manager to determine the maximum number of visits that can carry out tourism activities at Sangalaki Island NTP. Carrying capacity is intended to reduce the impact of tourism development on the ecological aspects of the area. In addition, the application of environmental carrying capacity is a manager's step to apply the concept of sustainable tourism at Sangalaki Island.

The research aims to quantify the environmental carrying capacity of both Petrified Forest Protectorate in East Greater Cairo and Hassanah Dome Protectorate in West Greater Cairo, with their sustainable use and preservation. The environmental carrying capacity works as a sustainable method not to exceed the environmental limits of nature reserves or in other words, the number of visitors does not exceed the maximum allowed for visiting the reserve. The methodology used in the International Union for Conservation of Nature (IUCN) has been used. The elements of the methodology are at 3 levels, namely, physical carrying capacity (PCC), which depends on the optimal rate of space used per capita and open period, real carrying capacity (RCC), which depends on environmental and social factors, and effective carrying capacity (ECC), which depends on administrative and operational capacity. The results of the research found that the Petrified Forest Protectorate (East of Greater Cairo) accommodates 186,286 visitor per day, and Hassanah Dome Protectorate (West of Greater Cairo) accommodates 26,612 visitor per day. In addition to assessing the level of the ecological carrying capacity index (ECCI), which measures the extent of support for the population and its activities, and by comparing the total environmental carrying capacity of the two protectorates that reached 212,898 visitors per day with the population of Greater Cairo (Cairo Governorate and Giza Governorate), which reached 17 million (Capmas, 2017), it was found that the environmental carrying capacity of the two protectorates is not sufficient to support recreational activities and environmental tourism for people of Greater Cairo.

Like in many Mediterranean countries, the coastal areas in Albania are recognised among the country’s great assets both from the development and environmental point of view. Their scenic beauty, favourable climate, diversity of ecosystems, rich cultural and historical heritage make them excellent resources for the development of tourism, which is recognised as one of most important sector contributing to country’s national long-term growth. During the last twenty years, the coastal areas in Albania have attracted the major part of tourism investments, which due to the lack of legislation, urban planning and institutional capacity for sustainable development, have been spontaneous and have negatively affected the sustainable use of natural recourses. Thus, the proper planning and implementation of sustainable tourism development model together with the assessment of tourism carrying capacity, take a paramount importance for sustainable development of the coastal resources. Yet such assessment in Albania is not considered part of integrated planning and management of the coastal areas, therefore the carrying capacity assessment (CCA) should be considered an extremely important tool that should be used during the course of drafting policies and development plans for coastal areas. The CCA should not only be considered as a concept, or scientific calculation that shows the precise number of tourists for a particular area. Instead, it should be used as a flexible management tool for sustainable development of tourism allowing for optimum level of capacity in a certain area. Carrying capacities should also be considered an integral part of defining development scenarios for a given area in order to ensure a harmonised and sustainable development for the future. This process should be more effective if it develops in sympathy with the nature and character of costal environment, tourist needs and local population’s expectation for tourism development. This article presents the necessity of assessing and applying the CCA concept during the course of developing various tourism development models of coastal areas, with a a strong focus at application of sustainable tourism development scenario.

A sustainable tourism approach is a requisite for ecotourism sites to provide a quality tourism experience. Tourism Carrying Capacity and Recreational Carrying Capacity is an influential concept in ecotourism management as for the assessment of the maximum permissible number of users in a destination. Bacuag Octopus Islet Adventure, a tourist destination, is anticipated as an area susceptible to carrying capacity issue which has not been recognized and no thorough implementation guidelines provided. This study focused on the determination of the site’s tourism and recreational carrying capacity. Questionnaires were administered to the participants of 385 tourists and 136 local residents. The tourism carrying capacity (TCC) was determined through the three levels of Boullon’s Carrying Capacity Mathematical Model (BCCMM) while recreational carrying capacity was determined utilizing the social norm/impact acceptability curve and importanceperformance matrix. As a result, the estimated TCC for the area of Bacuag Octopus Islet Adventure is 225 visitors per day. For the specific activities, the calculated carrying capacity for swimming, viewing, zipline, and skybike are 119, 10, 16, and 8, respectively. Using image capture technology, consecutively, the recreational carrying capacity by means of social indicators was 202 combining the tourists’ and local resident’s preferences. Thus, it is recommended to the management to implement the estimated carrying capacity on the visitors for the sustainability of the tourism area

This study aims to assess the outcomes of the transition period in terms of sustainable development in Lithuania in 1990–2004. The author aims to reveal the synergies and contradictions between the period of transition and the progress to sustainability. The research uses the conceptual framework for assessment of progress towards achieving sustainable development (APASD) for economies in transition (Kobus, 2005). The framework is based on three principles of sustainable development: the principle of carrying capacity, the principle of intergenerational equity and the principle of intragenerational equity. A three-tier system has been formed: each principle has been assigned two operational criteria and a number of sustainable development indicators. Finally, the framework has been applied to Lithuania unveiling the situation of sustainability and providing recommendations for policy response. The transition period has moved the national development closer to sustainability according to the principles of carrying capacity and intergenerational equity; however, it has not been so favourable for the principle of intragenerational equity.

Scientific assessment of tourism environmental carrying capacity is key to geotourism sustainable development. Based on exploring the definition of tourism environmental carrying capacity of geoparks and its characteristics, by adopting methods of AHP and literature review this paper focuses on establishing an appraisal indicator system of tourism environmental carrying capacity of geoparks. However, its more reasonable to give weights of appraisal indicators for a given geopark for geoparks greatly differ in terms of natural, economical and socio-cultural environment. Thus, taking Xinwen Karst World Geopark in Sichuan province as an example, the paper calculates weights of indicators of the parks tourism carrying capacity with AHP method and measures its tourism environmental carrying capacity by using average weighted method. The findings reveal that Xinwen Karst World Geopark is in mild overloading.

Purpose Uncontrolled and unsustainable urban development has a significant impact on the overall quality of the environment. Contemporary spatial management does not take into account the non-economic conditions of ecosystem functions and their biophysical limits, which results in a deterioration of the environment. Furthermore, urban development continues all over the world, which is associated with a projected population increase, particularly in cities. Therefore, there is need to include analyses in the field of environmental carrying capacity (ECC) for more sustainable spatial management and development. The ECC concept is a tool for sustainable development of human settlements. It could be defined as threshold level of anthropopressure, which the environment is able to balance and withstand without serious degradation and irreversible changes. The use of ECC assessment will help ensure the needs of the city’s residents, which are conditioned by the environment. The paper aims to discuss this issue. Design/methodology/approach This review study presents an overview of the ECC concept and its potential for use in spatial management at local level, especially for cities. The content analysis introduces definitions of spatial management and others main actions of spatial economy as well as the definitions of ECC. The overview of existing ECC models is a part of presented review. Findings The paper shows the ECC approach from global to local level on Poland as an example country. Originality/value The literature review identified that the idea of ECC could be a useful concept and tool for sustainable spatial development and management. This concept allows for verification of the resources and environmental state of given territory unit. Therefore, the assessment of ECC allows to verify if development of given area, for instance country, region or even city, is conducted within the framework of sustainable principles. Despite this, the assessment of ECC is not taken into account when future spatial management is defined. Thus, this circumstance could be a reason for this research area development.

Abstract With the quick development of social economy, the sharp contradiction between supply and demand of urban water resources is becoming much more obvious. Comprehensive assessment of urban water resources carrying capacity is of great significance to urban sustainable development planning. In this study, the urban water resources carrying capacity of Qingdao based on basin unit over 2010–2030 is predicted using analytic hierarchy process and system dynamics method. The results showed that the total water demand of all the nine basins have an upward annual trend from 2017 to 2030, among which the domestic water consumption increase obviously. The urban water resource carrying capacity indexes in all basins over 2017–2030 show a downward annual trend under the current social development model. So it is urgent to improve the water resource carrying capacity of each river basin by means of industrial structure optimization and upgrading and active development of new water sources.

The implementation of ecological restoration programs is intensively changing the original ecological carrying capacity and the status of ecological security. To evaluate the spatiotemporal variation of ecological carrying capacity and ecological security in China’s eco-engineering areas, an indicator system of ecological carrying capacity and ecological security should be developed. This study developed an evaluation indicator system that contains 29 indicators. The indicators were generated by long-time series and multi-source data. The indicator system presents the relationship between ecological carrying capacity and ecological security and reflects the dynamic change of them in eco-engineering areas. We selected the Three-River Headwaters Region (TRHR) and implemented the Ecological Conservation and Construction Program (ECCP) as a case study. The results showed the variation of ecological carrying capacity (ECC) and ecological security (ES) in the TRHR before (2000–2004), during early term (2005–2009), and during medium term (2010–2015) implementation of ECCP, and limiting factors of ecological carrying capacity and ecological security in TRHR was analyzed. The results showed that the ECC index and the ES index were significantly increase, indicating that the ECC improved and that the ES state got better in the TRHR after implementing ECCP. The water conservation was the major factors limiting the increase of the ECC. The leading factors limiting the improvement of the ES were educational expenditure before 2010 and turned into proportion of tertiary industry and investments for ecological restoration after 2010. The implementation of the ECCP has improved the ES state but has also resulted in new problems. It provides a scientific reference for future research on the indicator system of ecological carrying capacity and ecological security in eco-engineering areas and also has vital practical significance to guide the sustainable development of ecological restoration programs.

As one of the most crucial indices of sustainable development and water security, water resources carrying capacity (WRCC) has been a pivotal and hot-button issue in water resources planning and management. Quantifying WRCC can provide useful references on optimizing water resources allocation and guiding sustainable development. In this study, the WRCCs in both current and future periods were systematically quantified using set pair analysis (SPA), which was formulated to represent carrying grade and explore carrying mechanism. The Soil and Water Assessment Tool (SWAT) model, along with water resources development and utilization model, was employed to project future water resources scenarios. The proposed framework was tested on a case study of China’s Han River basin. A comprehensive evaluation index system across water resources, social economy, and ecological environment was established to assess the WRCC. During the current period, the WRCC first decreased and then increased, and the water resources subsystem performed best, while the eco-environment subsystem achieved inferior WRCC. The SWAT model projected that the amount of the total water resources will reach about 56.9 billion m3 in 2035s, and the water resources development and utilization model projected a rise of water consumption. The declining WRCC implies that the water resources are unable to support or satisfy the demand of ecological and socioeconomic development in 2035s. The study furnishes abundant and valuable information for guiding water resources planning, and the core idea of this model can be extended for the assessment, prediction, and regulation of other systems.

Beijing is now facing the intense water shortage problem. Evaluation of regional water resources capacity provides a scientific basis for further water resources utilization and social economic sustainable development. This study mainly focused on assessing the water resource carrying capacity in Beijing during the period from 1980 to 2011. The results indicated that the domestic and environmental water resource ecological footprint showed increasing trend, whereas agricultural and industrial water resource ecological footprint showed decreasing trend. The total water resource ecological footprint increased from 6.5×106 hm2 in 2011 to 6.8×106 hm2 in 2015 and 9.1×106 hm2 in 2020, respectively. Even taking the South-to North water transfer project, the water supply still not meet the serious water demand in Beijing with 10×108 hm3 of water shortage in 2020. Moreover, policies for reducing the water resource ecological footprint and increasing the water resource carrying capacity were put forward.

As a rigid constraint of the scale and speed of regional economic-social development, carrying capacity is an endogenous variable of regional sustainable development potential. Concepts such as ecological footprint and virtual water have been introduced into the research field of carrying capacity, but dynamic and comprehensive problems in carrying capacity have not been effectively solved. This paper attempts to overcome these limitations by taking the regional factor aggregation degree as the weight and the regional green GDP as the carrying object. Based on the economic-social supplying force, resource supporting force, and environmental constraint force, from the perspective of comprehensive factors assessment, we have constructed an evaluation system of regional carrying capacity index, including mineral, water, and bioecological resources, as well as labor and other factors, and evaluated the regional carrying capacity of 11 provinces and cities along the Yangtze River Economic Belt. The results indicate that (1) the supporting force of the resource subsystem becomes the most critical factor affecting the carrying capacity of the Yangtze River Economic Belt, and the cross-regional flow potential of resource factors increases the regional carrying capacity threshold. (2) The regional carrying capacity, economic-social, resource and environmental subsystems of the Yangtze River Economic Belt are steadily improving, and the overall trend is positive. The quantified dynamic evaluation of regional economic-social, resource and environmental carrying capacity provides a theoretical support for the construction of the Yangtze River Economic Belt eco-priority green development demonstration area.

Being the largest archipelagic state in the world (± 81 000 km of coastline), Indonesia has a great potential for developing the aquaculture industry. But, the accomplishment of sustainable practices and management systems are still in its infancy. Therefore, it is vital to improve aquaculture technology and develop management tools that address the need for an eco-friendly production process. In this manuscript, the Decision Support System software is applied for the management of sustainable floating net cage finfish cultures. This software integrates physical, chemical, biological properties and information on coastal uses to determine site selection, production carrying capacity, ecological carrying capacity and socio-economic assessment of 18 cases, focusing on the economic viability of Tiger grouper [Epinephelus fuscoguttatus (Forsskål, 1775)], Humpback grouper [Cromoliptes altivelis (Valenciennes, 1828)] and Leopard Coral grouper [Plectropomeus leopardus (Lacepède, 1802)] at three remote areas in Indonesia, including: Ekas Bay, Talise and Galang Island. The outcomes demonstrate that only Galang Island provides a suitable area of 12 940 ha with the estimated production carrying capacity of (0.5 to 366) t/annual per fish farm along with ecological carrying capacity are limited of (18 393 to 21 727) t/annual and economic evaluation highlighted that all cultures development are economically viable.

Overgrazing directly leads to grassland degradation, which is a serious constraint to the sustainable development of animal husbandry. In drylands, grassland biomass is highly heterogeneous in space and time. It is difficult to achieve sustainable utilization of grassland resources by focusing only on the average annual carrying capacity assessment obtained from grass yield. Here, we proposed a novel approach for assessing grassland carrying capacity, taking Zhenglan Banner (County) in Inner Mongolia as the study area. First, monthly grass yield at 30 m spatial resolution was estimated, derived from Carnegie–Ames–Stanford Approach (CASA) model and spatial and temporal adaptive reflectance fusion model (STARFM). Then, based on the degree of sand mobility and degradation condition of typical steppe, the utilization patterns for sandy land and typical steppe in different grazing seasons were developed separately to obtain available grass yield. Finally, the carrying capacity at the Gacha (Village)-scale was estimated and the current livestock carrying status was evaluated to facilitate the grassland refined management. In Zhenglan Banner, the carrying capacity was 237.46 thousand cattle-units in summer. The grassland resources are being overgrazed, with an overload rate of 19.32%. At Gacha-scale, the maximum reasonable stock density was ranged from 0.06 cattle-unit/ha to 0.42 cattle-unit/ha. Fifty-one Gachas exhibited livestock overload. This study is expected to provide technical support and scientific reference data for ecological conservation and grassland management in the study area, as well as in dryland pastoral areas of northern China.

The sustainable development of socioeconomic and environmental systems are highly dependent on water capital and water utilization efficiency. Nowadays, a significant portion of the world is facing water security issues due to a combination of various factors. As a result, socioeconomic and environmental systems are threatened. China is also currently experiencing problems. Water security assessment helps to identify key determining factors for optimal water utilization, so the authors present the Driving Forces-Pressures-Carrying Capacity-State-Impacts-Responses (DPSCIR) water security assessment framework. Unlike previous methods, the proposed framework incorporates the carrying capacity of the environment, and as a result, yields assessment results that are more realistic. As a case study, the proposed framework coupled with the entropy method is applied to assess the water security status of the One Belt and One Road (B&R) region in China. In addition, the water security level of the provinces and municipalities in this region are simulated for the time period from 2017 to 2022 using the Grey Prediction Model. The results show that Responses, State, Pressures, and Carrying Capacity Subsystems greatly influence water security of the region. According to the assessment, water security of the area improved from 2011 to 2016. The results portray the following trend among the three subregions of the study area, the water security of the 21st Maritime Silk Road (One Road) area is better than Silk Road Economic Belt (One Belt) and the Strategy Support and Pivotal Gateway (SSPG) of B&R areas. Generally, from the evaluation results it can be concluded that only focusing on the subsystem of Responses cannot entirely address the water security problems within the B&R area. Therefore, to ensure sustainable water security in the region and in the country, the government needs to design water resource management mechanisms that take all the subsystems into account.

The accelerated socioeconomic development has placed the coastal ecosystems under stress, which influences the sustainable development of coastal areas. Marine eco-environmental carrying capacity assessment (MECCA) can provide a scientific basis for coordinating coastal socioeconomic development and eco-environmental protection, ensuring a more effective marine ecosystem-based management approach toward sustainability. However, accurate assessment methods are still in the exploratory stage, as there has been a lack of systematic research and applications combining integrated MECCA with a unified method to underpin coastal management processes. In light of this issue, this study applied the marine eco-environmental carrying capacity in coastal waters (MECCCW) conceptual framework to support the establishment of an assessment indicator system for MECCA and used the regularization method and entropy method to determine weights. This study also applied the simplified state space model to comprehensively evaluate and analyze the marine eco-environmental carrying capacity (MECC) of coastal areas. Focusing on the coastal area of Sanya Bay, southern China, as the study area, we assessed the MECC for the period from 2015 to 2020. The state of the MECC was divided into three grades: load capacity, full-load capacity, and overload capacity. The results showed that (1) the MECCA indicator system in Sanya Bay included a total of three criteria and eight assessment indicators and (2) the weights of the environmental carrying capacity (ECC) and human activities (HA) were both relatively higher than that of ecological resilience (ER). The latter result indicates that either ECC or HA could play a more predominant role in the changes of the MECC state in Sanya Bay. The results also indicated that (3) for each criterion, ECC, ER, and HA were at load capacity from 2015 to 2020. In this instance, ECC and HA presented similar change trends in relation to the MECC state of Sanya Bay. Finally, (4) the overall Sanya Bay’s MECC was also at load capacity and weakened, fluctuating between 2015 and 2020. These findings indicate that the coastal area of Sanya Bay is capable of sustainable development, but that there is a need for further eco-environmental improvement. The results of this study can serve as a reference when decisions have to be made about coastal management from an environmental and ecological perspective. Furthermore, this method may provide a feasible approach for integrated MECCA in other coastal areas.

With the growth of population, water security has become the worldwide problem combined with severe environment pollution, quick economic development and irrational water allocation. Based on sustainable development, Water resources carrying capacity (WRCC) driven from physics originally has been proposed to solve it. The measurement of WRCC can tell decision-makers that how much population the water resource can feed, what degree water resources can support the economic and so on. Because the decision-makers can make adaptive decisions based on the correct evaluation of WRCC, the ways of the assessment of WRCC are very important. This paper focuses on how to measure WRCC by selecting three typical methods, fuzzy model of comprehensive evaluation, multiple criteria analysis (MCA) and system dynamics (SD) methods. The characteristics of these methods are good at solving the multi-objective and complicated problem in common which is the trait of WRCC. The differences of them are the specific process of analysis and evaluation.

The analysis of the relationship between regional resources and environment and human activities plays an important role in sustainable regional development. This study proposes the pressure–capacity–governance (PCG) model, an analytic framework for the assessment of the resources and environmental pressure (REP), carrying capacity (RECC) and governance (REG) levels over a large watershed scale, with the Yangtze River Economic Belt (YREB) as the study area. A limiting factor analysis is used to recognize the limiting factors of the regional RECC. The coupling analysis of resources and environmental pressure–capacity–governance identifies the regional potential and utilization direction. The research results are as follows. (1) The REP, RECC and REG levels of the YREB exhibit spatial differences. The REPs of the upper reaches are lower than those of the lower reaches, which does not match the RECC but matches the REG levels. (2) The proportions of unused land, water resources, and atmospheric environmental quality are the main limiting factors of the regional RECC. (3) The PCG analysis framework is used as the basis to divide the YREB into several subareas to analyse the resources and environmental potential carrying capacity and utilization direction of different types of region. This research may provide decision-making references for regional sustainable development at the large watershed scale.

As the centerpiece of ecosystems and human societies, river basins are complex social–ecological systems (SESs) that depend on the natural flow regime and the hydrologic variability to adapt to changes and absorb disturbances. Anthropogenic and climate change disturbances destabilize river systems. Therefore, a resilience question arises: What is the carrying capacity of a river basin, i.e., how much disturbance can a river basin take until the system undergoes a regime shift? To answer this question, this study aims to identify regime shifts, thresholds, and the carrying capacity of the transboundary Rio Grande–Rio Bravo (RGB) basin using 110 years of monthly streamflow data. To address this research question, first, gauged (regulated) and naturalized streamflow data is collected; if naturalized flows are not available, they are calculated through streamflow naturalization. Second, streamflow standardization is estimated using the streamflow drought index. Third, a regime shift assessment is performed using Fisher Index, and fourth, the nonparametric Mann-Kendall test is used to assess the Sustainable Regime Hypothesis which evaluates regime shifts and alternative regimes. Results demonstrate that resilience thresholds are surpassed, and regime shifts, including early warning signals, occurred in multiple locations of a transboundary basin. The present study highlights the importance of assessing the carrying capacity of a river basin; hence, evaluating regime transitions, including identifying early warning signals and thresholds, is critical in managing for sustainability and ecological resilience of SESs. Looking ahead, the integration of ecological resilience theory into water management has the potential to recognize the sustainable carrying capacity of river basins at the local, regional, and international scale.

Scientifically assessing the environmental carrying capacity (ECC) based on an evaluation of environmental quality standards (EQSs) holds great significance for establishing a long-term monitoring and early warning mechanism for resources and environmental carrying capacity (RECC) and for coordinating the sustainable development of ecological environments and regional economies. However, it remains unclear whether the evaluation of EQSs based on the short board effect is suitable for environmental assessments under different natural environments. In this research, Xinjiang is used as a case study. Based on the evaluation of EQSs, the atmospheric environmental carrying capacity (AECC), water environmental carrying capacity (WECC) and comprehensive environmental carrying capacity (CECC) are assessed using the short board effect and the weighted average. Additionally, the suitability of ECC evaluation in RECC evaluation is discussed. The results show the following: (1) In the atmosphere, the overload of inhalable particles (PM10) and fine particulate matter (PM2.5) is more serious, while in water, the overload of total nitrogen (TN) is more serious. (2) The percentages of the AECC, WECC and CECC in overloaded counties and cities based on the short board effect are 84%, 45%, and 51%, respectively, while the percentages based on the weighted average are 32%, 6% and 7%, respectively. (3) The extreme effects of a single pollutant can be eliminated by the weighted average, which is more suitable for environmental assessments in Xinjiang. (4) In evaluating RECC monitoring and early warning systems, weighted average evaluation is used to assess the elements, and short board effect evaluation is used in the comprehensive integration to prevent the influence of the amplification of a single index. Thus, the interference of non-key factors in the regional system on the final evaluation results is reduced.

Sustainable development, as a new idea of development, has become a source of worldwide concern. Many elements, such as society, economics, resources, and the environment, have a role in the long-term evolution of the ecological environment. It is an intricate mechanism. Based on previous research, this study investigates the relationship between environmental design and the long-term evolution of the ecological environment in the new age. The following are the specifics. First, the conceptual model of ecological sustainable development is constructed, and the “low-carbon idea” environmental design approach is addressed. Then, using Tianjin as an example, an assessment method for environmental sustainable development in environmental design is constructed based on summarizing past studies. The ecological features are included in the DPSIR model, and the “low-carbon concept” environmental design method is used in Tianjin Binhai New Area. The findings show that, with the continued development of Binhai New Area, the adjustment of industrial structure, and the gradual improvement of people’s awareness of urban sustainable development, the ecological environment’s sustainability index will improve, with per capita ecological carrying capacity rising from 2019 and the per capita ecological carrying capacity of agricultural and livestock products, which are 0.09 hm2 and 0.09 hm2, respectively, rising significantly. Since 2019, the per capita ecological footprint has also declined.

With the ongoing expansion of tourism, a conflict has arisen between economic growth in the tourism industry and environmental preservation, which has attracted the interest of government and academic groups. Because it enables the adaption of tourist activities and buildings in the tourism area in order to protect the natural resources of the scenic area while seeking economies of scale, the tourism environmental carrying capacity system is an essential tool for resolving this conundrum. It also enables tourist sites to grow sustainably while understanding their limitations and carrying capacity. This study uses Citespace 6.1.2 and VOSviewer 1.6.18 analysis software to conduct a bibliometric analysis and review of 297 articles on tourism environmental carrying capacity. This analysis includes early warning studies, assessment models and management tools, and analyses of keyword co-occurrence and emergent word co-occurrence. The article’s conclusion makes recommendations for further research, including the division of each interest group, improved dynamic forecast and early warning of tourism environmental carrying capacity, and the development of an objective, scientific model of tourism carrying capacity.

Abstract Population growth affects the competition between land uses. Inevitably, the increasing demand for natural resources causes severe damage to the urban environment. In addition, the potential of water resources can be a problem related to the supply of clean and suitable water to the community. The geological structure of the soil, disaster susceptibility, and issues with the clean water supply at the location are challenges in determining the development of residential areas in the Meulaboh Urban Area (MUA). This study aims to determine the carrying capacity of the Meulaboh urban settlement environment and the model for the distribution of settlements in the MUA. The environment’s carrying capacity is reviewed based on two aspects: the carrying capacity of settlements and water resources. In analyzing settlement modeling using MLC data from time-series images of Google Earth and Landsat 8-9 in 2011, 2016, and 2021 and using the MOLUSCE plugin on QGIS. The environmental carrying capacity assessment results show that the level of carrying capacity of settlements in the MUA is currently worth 1.69, and in 2041 it will reach a value of 1.26. While the carrying capacity of water resources in the current year is at a value of 2.8, and in 2041, it will reach a value of 2.0. Until 2041, it can still accommodate the population and meet the water needs to support population growth. However, it must still consider the disaster aspects and existing environmental constraints. So that sustainable development can be created that can balance development and the environment in the region.

As the most concentrated area of human activities, cities consume many natural resources and discharge a large amount of waste into the natural environment, which has a huge environmental impact. Most of the ecological and environmental problems, such as environmental pollution, global climate change, and loss of biodiversity, are related to urban systems. How to coordinate urban development with the urban ecological carrying capacity is related to the destiny of the city itself, and also to whether its surrounding areas can successfully achieve the goal of high environmental quality and sustainable development. At present, the theory and methods of urban ecological carrying capacity research are relatively new, which has caused problems for policy makers in practical applications. This paper proposes a theoretical framework for urban ecological carrying capacity assessment based on the analysis of ecosystem services supply and demand. Combined with multi-source spatial data and spatial model methods, the supply and demand of ecosystem services were spatially quantified. The capital city of China, Beijing, was the case study area for this research. The spatial differentiation of the supply–demand relationship of ecosystem services is formed. The priority areas for ecological carrying capacity improvement at pixel scale and at the administrative level are obtained, respectively. The results show that the first priority area is concentrated in the center of the urban area, accounting for 31.11% of the total area of Beijing. According to the secondary zone and the specific ecosystem service type, the ecological carrying capacity improvement strategy of different zones is proposed. This study provides a new perspective for investigating urban ecological carrying capacity and for identifying the priority areas for ecological carrying capacity improvement, and helps the policy-makers to design tailored policy actions.

Tourism is today one of the world’s largest industry. Tourism activities can generate both positive and negative effects on the conditions of the areas where visiting and fruition activities take place. Every form of human use of natural environment causes changes to the environment conditions. There is significant change in the scale, frequency and character of the visitors over the past few decades reflect new pressure on environment and the tourist destination. Today rapid trend of tourism along with the urbanization and other factor affect climate, so sustainable tourism is necessary. Sustainability has become an important policy issue in tourism, it grows discussion and criticism and increase need to understand nature of the limit of growth. Tourism mainly causes biophysical and social impact. In many cases scientist and planners have turned to the concept of tourism capacity as the way of formulating problem and management action to identify limits of a system to absorb changes. Carrying capacity is ultimately assessment tool for the exploration of natural and artificial resource which contributes to growth of tourism. Tourism carrying capacity has shifted now from a one-dimensional approach to incorporating environmental, social and political aspect.

The development of lobster production in pangandaran during the last decade (2006-2013) is in the range of 0.5 to 12 ton/year with an increasing trend in 2010-2013, but then increasingly decline since 2014. Pressure on lobster populations followed by a decrease in environmental carrying capacity may threaten the lobster's sustainability capacity to grow and develop naturally. This paper aims to analyze the reference values of the components required in the application of EAFM (Ecosystem Approach to Fisheries Management) to manage lobsters in Pangandaran. The six domains in EAFM include: a) resource domain, b) fishing techniques, c) habitat and ecosystem, d) economy, e) social, and f) institutional domain in general it will affect the sustainable management of lobsters in the Pangandaran. The method used in this research is AHP (Analytic Hierarchy Process). Research results show that the coral cover is an important aspect that cannot be separated from the management of lobster resources. Thus, the right management option is that both central and local governments need to reassure the effectiveness of the regulatory tools for the management of lobsters and conduct continuous and comprehensive lobster stock assessments while considering socioeconomic aspects in the context of sustainable lobster management in the Pangandaran.

Cobia fish cage is the most popular marine culture species raised in Phu Quoc Island, Vietnam. For its sustainable development, there is a need to determine the carrying capacity to avoid negative marine environmental impact in the future. This study was carried out to collect water samples each two months at the lowest and highest tides at four points around the farming area in Rach Vem, Phu Quoc Island, Kien Giang Province from February to October 2011. Water quality in cobia cage culture was surveyed to assess the environmental status of coastal aquaculture areas including seven parameters such as DO, COD, BOD, TSS, TN, TP and Chlorophyll-a. These parameters are suitable to rear cobia fish cage in this area. Nitrogen and phosphorus are considered as the principal nutrients produced by the cobia fish farm and affecting water environment. This study found that the carrying capacity for fish cage farming in the area is 290.96 to 727.81 tons (based on total nitrogen) and 428.64 to 1,383.88 tons (based on total phosphorus) from February to Au-gust 2011. The maximum number of cobia cages should be, based on total nitrogen, from 64 to 266 and, based on total phosphorus, from 94 to 253. Moreover, this study examined the possibility of remote sensing and geographic information system (GIS) technique based on Object-based Image Analysis (OBIA) method by THEOS imagery for mapping of cage culture facilities and detect the location for cobia cage culture in study area.

Nghiên cứu này được thực hiện thông qua việc thu mẫu môi trường nước mỗi 2 tháng theo mức nước triều cao nhất và thấp nhất tại 4 điểm quanh khu vực nuôi tại ấp Rạch Vẹm, huyện Phú Quốc, tỉnh Kiên Giang từ tháng 02-10/2011. Chất lượng nước khu vực nuôi thủy sản cũng được khảo sát với 7 chỉ tiêu gồm DO, COD, BOD, TSS, TN, TP, Chlorophyll-a. Các thông số chất lượng môi trường này phù hợp nuôi cá bớp tại khu vực nghiên cứu dựa trên tiêu chuẩn chất lượng môi trường. Trong nghiên cứu này, đạm và lân là 2 thông số được sử dụng để tính toán sức tải môi trường. Sức tải môi trường được tính toán cho khu vực nuôi cá bớp dao động khoảng từ 290.96 tấn đến 727.81 tấn (tính trên hàm lượng đạm tổng số) và từ 428,64 tấn đến 1.383,88 tấn (tính trên hàm lượng lân tổng số) trong thời gian từ tháng 2 đến tháng 10 năm 2011. Số lượng tối đa lồng bè nuôi cá bớp khoảng từ 64 đến 266 (đạm tổng số) và từ 94 đến 253 (lân tổng số) dựa vào phân tích hồi quy tương quan. Bên cạnh đó, công nghệ viễn thám và hệ thống thông tin địa lý (GIS) đã được ứng dụng bằng cách sử dụng ảnh THEOS để xác định vị trí và phân bố không gian khu vực nuôi cá lồng bè dựa trên phương pháp phân tích đối tượng theo hướng (OBIA).

The quest for Africa’s development breakthrough appears to be closely related to the African Continental Free Trade Area (AfCFTA). The Economic Commission of Africa believes the move could solve chronic poverty and joblessness prevailing on the continent. However, the benefit of hindsight reveals limits set by the laws of thermodynamics on the extent to which economic activities can be most beneficial to humanity. The motivation to expand trade thrives on energy for extraction, production and consumption, each of which yields undesirable waste products. The need for sustainable development has been a response to the limits imposed by excessive waste, stretching environmental carrying capacity to the breaking point. Thus, in order not to repeat the development errors of the past, Africa’s Continental Free Trade Area needs to ascertain the extent and cost of resultant environmental damage. Clearly, AfCFTA is yet to consider such effects. The COVID-19 pandemic, however, should be a reminder of how devastating a collision between economic activity and the natural environment can be. Existing studies on AfCFTA have so far been restricted to quantifying the effects of tariff reductions, non-tariff barriers and trade facilitation. This study, however, assesses the outcomes of the efforts being made to achieve the goals of AfCFTA, from an environmental economics analytical framework, in line with tenets of sustainable development. It employs data mainly from the World Bank and AfCFTA Secretariat to analyze the welfare effects of AfCFTA through resultant deforestation, solid waste management and climate change adaptation. The study found the resulting environmental damage to be US$ 744.71 billion, which far exceeds the projected AfCFTA benefits of US$450 billion to be realized by 2035. Thus, in its current form, AfCFTA will reduce the economic welfare of Africa by at least US$294.71 billion by 2035. While in the formative stages, AfCFTA will be better served if stakeholders can pay attention to the call for a fully operational plan to offset the impending environmental damage, which cannot be taken for granted if Africa wants sustainable development.

The evaluation of urban comprehensive carrying capacity (UCC) is of great importance in maintaining urban socio-economic sustainable development. However, UCC is still in its nascent period with limited applications and a lack of credible assessment methods. To enrich this field, this study constructed an objective scientific index to evaluate the UCC of the Yangtze River Delta (YRD) region from a four-dimensional perspective, examining economy, society, environmental, and transportation subsystems. The improved entropy method based on 18 weighted indicators was used to measure the UCC of the 26 cities of the YRD for the period 1990–2018. Results indicate that nine cities were overloaded in 2018, meaning comprehensive carrying capacity demand exceeds supply, and the other seventeen were in loadable condition, meaning such demand did not exceed supply; the social and transportation subsystems are the most important because their index weights and UCC levels are higher than the other two subsystems; the overall UCC for all cities in the YRD is at a medium level, and there are large disparities between the various cities. The empirical results imply that the government should take effective measures to improve UCC in these cities, combining cities’ specific advantages to enhance the efficiency of resource allocation and utilization and improve carrying capacities, and changing the mode of economic development. Based on UCC levels, it is also important to improve environmental conditions and coordination and integration in the development of urbanization. Policy implications on improving UCC have been highlighted in the final section.

Statistical catch-at-age analysis (SCAA) is applied to data for Antarctic minke whales. The SCAA model is spatially-structured, can model multiple stocks of minke whales, and can utilise several data types for parameter estimation. The application to Antarctic minke whales considers two stocks (I and P) in five areas which cover Antarctic Areas III–E to VI–W. The parameters of the model (annual deviations about the stock-recruitment relationship, changes over time in carrying capacity, density-dependence parameters related to productivity and carrying capacity, and the parameters which determine growth by stock, age-specific natural mortality by stock, and vulnerability by area and ‘fleet’) are estimated by fitting the model to data on catches, catch-at-length, conditional age-at-length, and estimates of absolute and relative abundance. A reference case analysis is selected, and sensitivity explored using retrospective analyses and by varying the assumptions on which the reference case analysis is based. The reference case analysis is able to mimic all of the data sources adequately. Most of the analyses (reference and sensitivity) indicates that Antarctic minke whales in the assessed area increased from 1930 until the mid-1970s and have declined thereafter, with the extent of the decline greater for minke whales in Antarctic Areas III–E to V–W than for those further east. Natural mortality is consistently estimated to be higher for younger and older individuals than for individuals of intermediate age. Estimates of MSYR1+ (the exploitation rate on animals 1 and older at which sustainable yield is maximised) are presented, but are unreliable owing to the lack of contrast.

Hoven’s carp is an indigenous species of freshwater fish which is hihgly potential to be cultured in larger scale. It is omnivorous tend to be herbivorous fish so that it can save cost of feed. Sustainable management is needed in order to optimize the benefits that can be obtained from hoven’s carp aquaculture activities. It needs to pay attention to four dimensions of sustainable development (ecological, economic, socio-cultural and technological) to avoid problems of aquaculture. The purpose of this study was to assess the status and management strategy formulation for sustainable aquaculture of hoven’s carp in Jambi municipality using the Rapfish application. The results of the sustainability analysis of hoven’s carp aquaculture in Jambi municipality showed less sustainable with an index value of 46.60%, a stress value of 12.93% and a R2 value of 95.72%. Based on the leverage analysis, there are 14 sensitive attributes that are used to improve the sustainability of hoven’s carp aquaculture including availability of aquaculture land, land carrying capacity, marketing access, efficiency in the marketing chain, price fluctuations, availability of venture capital, knowledge of hoven’s carp fish aquaculture, fish farming experience, level of independence of farmers, availability of broodstock and seed, availability of supporting containers for aquaculture, feed independence.

Abstract In order to assess the water resources carrying capacity (WRCC) of Hubei province, an improved catastrophe progression method based on M-K test and correlation analysis was established. This model includes evaluation, abrupt change test and correlation analysis. It can make a comprehensive assessment of water resource carrying capacity in a certain area. The evaluation results of this model are clear and can effectively avoid the effects of subjective weight and, in addition, it can also streamline the index system. We applied the model to study the WRCC of Hubei province from 2005 to 2016, considering the supply and demand of water resources, ecological environment, economy and society. The results showed that the WRCC of Hubei province is at the ‘weak’ level, presenting a certain development and utilization potential, but it must be strictly controlled and moderately developed. The WRCC of Hubei province is improving, but must be adjusted by water conservation facilities and long-term management policies to prevent the foreseeable deterioration. Water supply and demand systems and ecological environment systems were found to be the driving factors of WRCC through correlation analysis. This approach gives the decision-makers suggestions about water resource sustainable utilization.

The purpose of this study is to assess the suitability of coastal tourism in the Diyonumo Island and the carrying capacity of the area to support the sustainability development of coastal tourism in the island. The study was conducted at Diyonumo Island, Deme II Village, East Sumalata District, North Gorontalo District, Gorontalo Province, from September to November 2020. The data collection was done by observation and surveys. Study location was divided into 4 stations with an assessment of 3 categories designated for beach tourism, namely recreation, fishing, and camping. Tourism Suitability Index (TSI) and carrying capacity were calculated from the obtained data. The results showed that the island has the potential to be developed into a tourist area with the TSI value for the categories of recreational, fishing, and camping is categorised ‘very suitable’. Moreover, the carryingcapacity for recreation, fishing, and camping are 1.916 people/day, 104 people/day, and 125 people/day, respectively. The most important thing to do in order to achieve a sustainable development and management is by properly use and manage the resource of the island and this effort can be done by government through community empowerment programs.Indonesian title: Pengembangan wisata pantai berbasis potensi dan daya dukung kawasan Pulau Diyonumo, Kecamatan Sumalata Timur, Gorontalo-Indonesia
