Environmental Science and Pollution Research, 2021
In recent years, the exploration and sustainable development of islands is getting more and more attention around the world. However, the development of China's islands is somewhat disorder and spatial unbalanced. Therefore, we need to conduct a scientific assessment of the islands in order to fully understand the islands. In this paper, We analyze the possible development path of the islands by evaluating the value of the islands. To be specific, we present an extensive evaluate model design based on analysis of the environmental resources conditions, economic values, and existing problems of the seven typical islands in China. This model is applied to evaluate the sustainability levels and development advantages of seven typical islands. The island's evaluation results are consistent with the island's actual development level, which proves that the model is believable. Generally, the more indicators involved in the evaluation model, the more accurate the evaluation result will be. However, numerous indicators will cause two problems. One is that some indicators are highly correlated and make the evaluation results inaccurate. Therefore, it is necessary to remove redundant indicators; the other is that the calculation process will be cumbersome. In this study, we used factor analysis to solve the problems, making the evaluation results more accurate. Meantime, the experiment has proved that the model can simultaneously use multiple types of islands as samples for unified evaluation.
Measuring the Attractiveness of Small Islands. A Tool for Sustainability
Islands exhibit specific and unique problems, which ought to be studied in a special and separate way from the territories of the mainland. These problems and characteristics are more intense in small islands. Furthermore, islands comprise unique entities with specific natural, anthropologic and historical characteristics, which subsequently necessitate their examination as units of analysis. The problems that islands, and especially small ones, face impose an impediment to their sustainable development process. In order to blossom, islands must at the same time cope with the improvement of their residents' living conditions. This can be accomplished through the elaboration of the notion of 'attractiveness', as an operational definition of sustainable development. This paper argues that in order to rejuvenate, islands need to ameliorate their attractiveness. By this way they will sustain their residents and in time will attract new ones. Physical isolation is a factor that cannot be changed but only accounted for. Yet, other factors, such as population potential, existence of employment opportunities, quantity of infrastructure and quality of services offered, environmental quality and safety, can, if addressed properly, constitute the cornerstone of islands' sustainable development. Taking into account the above-mentioned factors, an attractiveness index (AI) is created and used for the classification of islands. This index is applied to the small islands of the exclusive Greek insular prefecture of Cyclades, as a tool for sustainability.
A Fuzzy Multi-Criteria Approach for Sustainable Island-based Tourism Development
Scientia Iranica
This paper aims to propose a framework by which decision-makers can evaluate and compare alternatives for sustainable island-based tourism development. The uncertainties and risks involved in information and judgment within the evaluation process were taken into account by using a hybrid approach, which combined the Delphi method, fuzzy set theory, and a discrete multi-criteria method based on prospect theory called TODIM (an acronym in Portuguese of interactive and multiple-criteria decision making). The decision making model examined 3 different techniques for aggregating the viewpoints of different decision-makers and explored how the aggregation technique would affect the ranking of the alternatives. To demonstrate the potential application of the proposed approach, it was examined for the development of Hendourabi Island (Iran) for tourism. Results showed that among the 3 alternative development plans, decision-makers preferred the medium-size development alternative, since it offered a balance between benefits of tourism market and costs of project development under an uncertain future. It also allowed for adaptive management. Results also showed that the proposed approach, which reduced loss regret in decision-making under uncertain future, could be used effectively for planning the island development under an uncertain dynamic future considering the risk and uncertainty associated with human judgment.
Sustainability Variables and Indicators Small Islands: Literature Review
International Journal of Advanced Research, 2020
The development of small islands in the last few decades has not shown optimal and sustainable results. This problem occurs on small islands with a high population density coupled with high socio-cultural and economic activities with dense settlements as estimating indicators. This study aims to determine the variables and indicators that are able to formulate an index of the sustainability of small island development. This research method uses a scientific literature study approach related to the sustainability of development and management of small islands so that from the literature review, the most appropriate variables and indicators are used to formulate a new index in determining the sustainability of small island development.
The Sustainable Island Tourism Evaluation Model Using the FDM-DEMATEL-ANP Method
Sustainability
The purpose of this study is first to propose a comprehensive evaluation model for sustainable island tourism, and then to provide guidelines and suggestions for the development thereof. Based on the advantages of using fuzzy set theory, this study’s method included the fuzzy Delphi method (FDM), the decision-making trial and evaluation laboratory (DEMATEL), the analytic network process (ANP), and FDM- DEMATEL-ANP (FDANP). From the literature review results and experts’ surveys, the dimensions of the evaluation criteria for sustainable island tourism are governance, economy and finance, socio-culture, and the environment. Compared with other studies, its major contributions and differences are the governance and finance dimensions, and the evaluation criteria for the marine industry, marine cultures, and marine environments. The findings show that the relative importance of the dimensions from high to low are economy and finance, governance, the environment, and socio-culture. The t...

Given the intensity and frequency of environmental change, the linked and cross-scale nature of social-ecological systems, and the proliferation of big data, methods that can help synthesize complex system behavior over a geographical area are of great value. Fisher information evaluates order in data and has been established as a robust and effective tool for capturing changes in system dynamics, including the detection of regimes and regime shifts. The methods developed to compute Fisher information can accommodate multivariate data of various types and requires no a priori decisions about system drivers, making it a unique and powerful tool. However, the approach has primarily been used to evaluate temporal patterns. In its sole application to spatial data, Fisher information successfully detected regimes in terrestrial and aquatic systems over transects. Although the selection of adjacently positioned sampling stations provided a natural means of ordering the data, such an approach limits the types of questions that can be answered in a spatial context. Here, we expand the approach to develop a method for more fully capturing spatial dynamics. The results reflect changes in the index that correspond with geographical patterns and demonstrate the utility of the method in uncovering hidden spatial trends in complex systems.
Strategic Assessment and Economic Evaluation: The Case Study of Yanzhou Island (China)
Sustainability, 2019
This paper proposes an interdisciplinary multi-level decision-making procedure for supporting an ongoing process of rural development of Yanzhou Island (China). A multi-methodological evaluation approach based on the combined use of different evaluation tools has been developed in order to take into account the economic, social, environmental and cultural aspects of the planning process. An experts’ panel has been involved in research since the preliminary phases of the evaluation with the aim of helping the structuring of the decision problem and discussing the outcomes of the analysis. The proposed approach allowed to understand the potentials and weaknesses of the area and to design the most suitable solution for the case study selected. The interdisciplinary nature of this process had given the opportunity to co-design and re-define the master plan in line with the expressed priorities. The master plan of the new district encourages landscape enhancement and promotes the economi...
Organization and Evaluation of a Sustainable Islands Network
International Journal of Sustainable Development and Planning, 2011
The DAPHNE network (ΔΑΦΝΗ, in Greek) has been developed for the Aegean islands with the objective to promote the sustainable development of a region that is ecologically sensitive and culturally rich. The basic tool employed is an evaluation-certification system that results in the yearly award of a sustainability badge for each qualified island. The evaluation process includes a series of activities, such as examining the condition in each island and detecting environmental pressures, defining widely acceptable sustainability priorities, and scheduling and assessing relevant actions. There are two basic axes in the evaluation methodology: island condition and program actions. Ten thematic sectors of sustainable development that are considered as including the maximum number of island condition and action cases have been selected. Sustainability assessment is done by assigning scores to a series of factors and by calculating a total score. Islands with yearly scores greater than or equal to a pre-defined minimum receive (or retain) the sustainability badge for that year.
RenewIslands methodology for sustainable energy and resource planning for islands
2008
With respect to energy supply, most of the islands depend on importation, mainly from oil and its related products, and others are dependant on weak electricity grid connexions with mainland. Scarce resources are used inefficiently, supplying end-use energy and other life-supporting commodities, like power, heat, cold, transport fuel, water, waste treatment and waste water treatment. It is possible to integrate various flows and decrease the energy intensity, although the task is situation dependant and involves a large number of different systems. RenewIslands methodology for the assessment of alternative scenarios for energy and resource planning is presented here, and applied to several islands. The methodology helps in choosing energy and resource flows integration, based on the island needs, its resources, and the applicable technologies.
