Comprehensive Evaluation and Spatial Difference Analysis of Regional Ecological Carrying Capacity: A Case Study of the Yangtze River Urban Agglomeration.
International journal of environmental research and public health, 2019Co-Authors: Yuanyuan Wang, Benhong Peng, Guo Wei, Ehsan ElahiAbstract:Ecological Carrying Capacity is an important factor of sustainable development for cities, and a critical part of achieving the coordinated development of the social economic and Ecological environment for urban agglomerations. In order to evaluate the regional Ecological Carrying Capacity and provide a basis for decision-making for regional sustainable development, this paper constructs an Ecological Carrying Capacity model for the urban agglomeration from two dimensions: Ecological Carrying elastic force and Ecological Carrying pressure. The analytic hierarchy process is utilized to determine the weights of nine indices in these two dimensions. For the Yangtze River urban agglomeration, the comprehensive index of its Ecological Carrying Capacity is investigated quantitatively, and the spatial distribution map of its comprehensive index measuring Ecological Carrying Capacity is computed. The results show that Nanjing, Yangzhou, Taizhou, and Changzhou are in the stage of high load Carrying; Suzhou, Wuxi, Nantong, and Zhenjiang are in the stage of low load Carrying. In addition, the environmental protection investment has the greatest impact on Ecological Carrying elastic force, followed by the proportion of the tertiary industry; wastewater discharge has the greatest impact on Ecological Carrying pressure. The level of Ecological Carrying Capacity varies within the region. It is necessary to take measures to increase the Ecological Carrying elastic force and reduce the Ecological Carrying pressure according to the actual conditions in each region. Meanwhile, exchanges and cooperation between different regions should be strengthened to stimulate the coordinated and sustainable development.

dynamic evolution of Ecological Carrying Capacity based on the Ecological footprint theory a case study of jiangsu province
Ecological Indicators, 2019Co-Authors: Benhong Peng, Ehsan Elahi, Guo WeiAbstract:Abstract The regional Ecological environment has been facing serious challenges in China due population growth and urbanization. Therefore, it is imperative to study dynamic evolution of Ecological footprint and Ecological Carrying Capacity based on the Ecological footprint theory. For this purpose three cities namely, Nanjing, Nantong, and Huai’an of Jiangsu province of China were analyzed to estimate the Ecological status of the province and its internal differences by discussing the dynamic evolution characteristics of the provincial and typical urban Ecological conditions. The results indicated that per capita Ecological Carrying Capacity of Jiangsu province has increased; however, the Ecological deficit of cultivated land was generally large due to poor public land use planning. In order to protect cultivated land, and improve its utilization it is recommend to efficient use of resources to improve the Ecological Carrying Capacity, strengthen Ecological restoration to reduce Ecological deficits, and provision of equal facilities in village areas to reduce urbanization.

evaluation and prediction of the Ecological footprint and Ecological Carrying Capacity for yangtze river urban agglomeration based on the grey model
International Journal of Environmental Research and Public Health, 2018Co-Authors: Benhong Peng, Yuanyuan Wang, Ehsan Elahi, Guo WeiAbstract:The conflict between economic development and environmental protection has become increasingly prominent in the urbanization process of the Yangtze River urban agglomeration, the most economically developed region in Jiangsu Province in China. In order to investigate the sustainable development status, and thus provide decision support for the sustainable development of this region, the Ecological footprint model was utilized to evaluate and analyze the Ecological footprint per capita, the Ecological Carrying Capacity per capita, and the Ecological deficit per capita for the period from 2013 to 2017. Furthermore, the Grey model is employed to predict the development trend of the Ecological footprint for 2018 to 2022. The evaluation results show that the Ecological footprint per capita has been increasing year by year since 2013, reaching a peak of 2.3897 hm2 in 2015 before declining again. In the same period, the available Ecological Carrying Capacity per capita and the Ecological footprint per capita basically developed in the same direction, resulting in an Ecological deficit per capita and gradually increasing from 2013 to a peak of 2.0303 hm2 in 2015 before declining. It is also found that the change of Ecological Carrying Capacity is not substantial, and the change of the Ecological deficit is mainly caused by a huge change of the Ecological footprint. The forecast results show that the Ecological deficit per capita will reach 1.1713 hm2 in 2018, which will be another deficit peak after 2015. However, in the later period until 2022, the Ecological deficit per capita will begin to decline year by year. These results can provide effective inspirations for reducing the Ecological deficit of the Yangtze River urban agglomeration, thus promoting the coordinated development of the economy and environment in this area.

calculating Ecological Carrying Capacity of shellfish aquaculture using mass balance modeling narragansett bay rhode island
Ecological Modelling, 2011Co-Authors: Carrie J Byron, Jason S Link, Barry A Costapierce, David A BengtsonAbstract:Abstract Increasing growth in the aquaculture industry demands ecosystem-based techniques for management if that growth is to be Ecologically sustainable and promote equity among users of the ecosystems in which it occurs. Models of Carrying Capacity can be used to responsibly limit the growth of aquaculture in increasingly crowded coastal areas. Narragansett Bay, Rhode Island, USA is one such crowded coastal region experiencing a rapid increase in bivalve aquaculture. An ecosystem mass-balance model was used to calculate the Ecological Carrying Capacity of bivalve aquaculture. Cultured oyster biomass is currently at 0.47 t km −2 and could be increased 625 times without exceeding the Ecological Carrying Capacity of 297 t km −2 . This translates to approximately 38,950 t of harvested cultured oysters annually which is 4 times the total estimated annual harvest of finfish. This potential for growth is due to the high primary productivity and large energy throughput to detritus of this ecosystem. Shellfish aquaculture has potential for continued growth and is unlikely to become food limited due, in part, to the large detritus pool.

integrating science into management Ecological Carrying Capacity of bivalve shellfish aquaculture
Marine Policy, 2011Co-Authors: Carrie J Byron, Barry A Costapierce, David A Bengtson, John CalanniAbstract:Abstract Ecosystem-based management (EBM), despite the best efforts of managers, researchers, and policy makers, often falls short of its intended purpose resulting in inadequate protection of resources. Coastal habitats are particularly vulnerable to poor management due to high use and potential for user conflict. EBM can be improved when it is informed by Ecological science and considers the socio-economic needs of the community. Communication between scientists and stakeholders can help to prevent adverse outcomes while enhancing protection and sustainability of the coastal environment. In the research presented here, a framework is used to guide and enhance communication between scientists and stakeholders for sustainable management of resources and equity of all users. The outcome of this applied framework is a long-term plan to guide the management of an oyster aquaculture industry using Carrying Capacity as an estimate for the basis of management decisions. Central to the framework is the Working Group on Aquaculture Regulations (WGAR), which represents a diverse group of stakeholders. The WGAR worked closely with Ecological modelers over a two-year period using mass-balance modeling to calculate Ecological Carrying Capacity for oyster aquaculture in two ecosystems: Narragansett Bay and a set of highly flushed temperate lagoons in Rhode Island, USA. Collaboration between scientists and the WGAR greatly improved the models and stakeholder understanding of the science and acceptance of the results. Aquaculture is increasing in coastal regions world-wide and this framework should be easily transferable to other areas suffering from similar user conflict issues.

modeling Ecological Carrying Capacity of shellfish aquaculture in highly flushed temperate lagoons
Aquaculture, 2011Co-Authors: Carrie J Byron, Jason S Link, Barry A Costapierce, David A BengtsonAbstract:Abstract Lagoons are some of the most productive systems on the planet — not only for aquaculture, but for fisheries, recreation, and as nurseries for many important species. These systems are also highly susceptible to degradation. Aquaculture is a rapidly increasing industry capable of impacting these sensitive systems. Dense human populations and intensive multiple uses of Ecologically sensitive coastal waters have forced resource managers to evaluate the impact of expanding shellfish aquaculture to ensure sustainable development. A mass-balance ecosystem model of highly flushed temperate lagoons in Rhode Island, USA was constructed to calculate the Ecological Carrying Capacity for shellfish aquaculture. Cultured oyster biomass is currently 12 t km −2 live weight and could be increased to 62 times this value before exceeding the Ecological Carrying Capacity of 722 t km −2 . The lagoons were found to be a detritus-dominated system with high energy throughput which may permit the high Capacity of the system for additional shellfish biomass allowing managers to consider expansion of shellfish aquaculture to densities much higher than comparatively oligotrophic systems could support. Managing by Ecological Carrying Capacity follows an Ecological Approach to Aquaculture by maintaining Ecological integrity and the sustainability of the aquaculture industry as well as other human uses of the lagoon system.
