Abstract
Sustainable development is the concept of coordinating people and the environment and achieves contemporary development without compromising the interests of the next generation. It can also be thought of as not exceeding the biosphere’s carrying capacity. Urban metabolism emphasizes resource recycling and use to achieve balance between resource input and product output in urban areas. However, the scale of cities has expanded rapidly in recent years along with resource and energy demands. Waste and pollution also cause major threats to the environment and ecology. Given increasingly serious environmental problems, the original linear metabolism must be converted into a cyclical one to ensure urban sustainability. From the policy implementation report of Taipei City, this study used the fuzzy Delphi method to develop evaluation factors and integrated this with the analytic network process decision-making tool to determine the priority weights of each policy and evaluate development strategies for urban development based on the metabolism concept. The study results reveal that natural environmental sustainability and sustainable energy strategies were prioritized plans for evaluating urban development with the metabolism concept, and the results can be used as a reference for future urban development strategies.
Highlights
Sustainable development can be interpreted as maintaining or expanding the production and use of resources, maintaining the integrity of the resource base so that natural resources are available to humans in perpetuity and are not depleted to the detriment of the production and livelihood of future generations
Due to similarities in structure and function between natural and social ecosystems, the metabolism concept has gradually been introduced into the study of social ecosystems, which mainly refers to the materials required by urban residents for living and wastes and pollutants produced by them
The network relationship of the analytic network process (ANP) can present correlations between criteria and calculate limiting influence between each control criterion to form a supermatrix. (Figure 4) This study explored nine indicators screened from the fuzzy Delphi method
Summary
Sustainable development can be interpreted as maintaining or expanding the production and use of resources, maintaining the integrity of the resource base so that natural resources are available to humans in perpetuity and are not depleted to the detriment of the production and livelihood of future generations It can be interpreted as developmental needs for material and energy not exceeding the regeneration capacity and waste absorption ability of the biosphere [1]. Due to similarities in structure and function between natural and social ecosystems, the metabolism concept has gradually been introduced into the study of social ecosystems, which mainly refers to the materials required by urban residents for living and wastes and pollutants produced by them. This study established evaluation indicators of urban metabolism in Taiwan to explore the urban development strategies of Taipei City through social network analysis of metabolism and compared both analysis methods.
