A sustainability index for small island developing states

This paper proposes a novel approach to measuring the progress of small island developing states (SIDS) towards sustainable development (SD) as set by the UN Sustainable Development Goals 2030. Currently, these goals do not provide adequate guidance on how countries might measure their progress towards sustainability. We use these goals and a subset of their targets to develop an index with concrete targets, through the use of pertinent sustainability indicators, that SIDS should aim to achieve a sustainable society. In addition to the three categorical pillars of SD (social, economic and environmental), we included the category Climate Change and Disaster Management (incorporating Disaster Risk Reduction). The basis of our decision is that the UN and the Intergovernmental Panel on Climate Change have both recognized the vulnerability of SIDS to both environmental hazards. Our index scores a total 70 individual indicators for the four categories to track the progress of a SIDS towards a sustainable society. Using the Caribbean nation, Republic of Trinidad and Tobago, as our SIDS case study, we report the average of the scores for each category to illustrate its progress towards sustainability. Overall Trinidad and Tobago is slowly progressing towards a more sustainably developed society. Our results show that the nation is only moderately successful regarding progress in three traditional pillars of SD, social, economic and environmental. However, Trinidad and Tobago scores poorly in the Climate Change and Disaster Management category and needs to improve in this area especially due to its vulnerability.     

Integrating disaster risk reduction in national development planning: experience and challenges of Jamaica

It is generally recognised by the disaster risk management and development communities that disasters have a negative impact on development, and indeed can set back development by years. This realisation led to a new paradigm for the management of hazards and their impacts, namely an integrated approach which emphasises disaster risk reduction being incorporated into national development planning. Awareness, however, does not necessarily translate into implementation. ‘Reduce the underlying risk factors’, Priority for Action 4 of The Hyogo Framework for Action 2005–2015, reported the lowest average score for progress of the five priority areas. Challenges to progress, as reported by Governments included inappropriate development practices, high levels of poverty and other factors which increase vulnerability. Various authors have recognised the difficulty of consistently and successfully integrating disaster risk reduction into development planning. This integration is particularly challenging for Small Island Developing States (SIDS) which face high exposure to hazards, vulnerable populations and limited resources, often both human and financial. The efforts of Jamaica, a Caribbean SIDS, at integrating disaster risk reduction into national development, and some factors which proved to be important in making progress are presented here. This retrospective paper is written from the perspective of a participant observer and traces developments in disaster risk management over three decades, 1980–2010. Integration and inclusiveness, use of quantitative methods and application of risk assessments are identified as being important in gaining acceptance for disaster risk reduction.

The challenge of sustainable development in small island developing states: case study on tourism in the Caribbean

Small island developing states (SIDS) in the Caribbean have long specialised in primary commodity exports, and traditional export sectors continue to be a major source of employment. The challenge of sustainable development for the Caribbean SIDS has two dimensions. The first is to adjust to the economic and social impact of the loss of preferential markets for traditional exports and of the dismantling of the ISI apparatus erected during the post-World War II period. The second is to ensure that existing and new patterns of production and consumption comply with the criteria for sustainable development, which is here defined as environmental, socio-cultural and economic sustainability.
This article outlines the potential contribution of sustainable tourism to the larger goal of sustainable development in the SIDS in the Caribbean. It reviews current literature on sustainable development and sustainable tourism, particularly their application to the Caribbean SIDS, and evaluates the Caribbean tourism industry from the point of view of sustainable tourism. Conclusions are drawn and proposals made for a policy-oriented agenda in support of the quest for sustainable tourism in the SIDS in the Caribbean.     

Evaluating efforts to build sustainable WEEE reverse logistics network design: comparison of regulatory and non-regulatory approaches

Many developing countries such as Turkey are still making an effort on building an infrastructure for waste of electrical and electronic equipment (WEEE) reverse logistic network design (RLND) processes. It is obvious that policies/laws/regulations related to WEEE management provide a sustainable framework for implementation in the RLND. The question is here: Does the implementation of WEEE directives make sense in terms of reducing the total cost of the network in the long term? This study aims to compare regulatory and non-regulatory situations of WEEE RLND in developing countries by formulating two models named as ‘regulatory’ and ‘non-regulatory’. Model 1 is considered as sustainable with economic, environmental and social goals, and the quotas imposed by the environmental directive are taken into consideration as the data of product return amount. In Model 2, only economic goal is considered, and product return amount is forecasted using Artificial Neural Network (ANN). A case study is conducted in a recycling company in order to evaluate performance of the proposed models. This study contributes to the relevant literature by (1) comparing the regulatory and non-regulatory situations RL models explicitly and (2) proposing ANN model to forecast EEE product return or WEEE quantity for non-regulatory situation.

GIS与环境模拟在环境地学研究中的作用和意义

21世纪全球环境问题将更加突出,环境地学应为研究、解决环境问题做出更多的贡献。但是,环境地学研究所采用的方法和手段还不能满足客观的需要。文章着重讨论了环境模拟系统(EnvironmentalImitationSystem,EIS)的建立及EIS与地理信息系统(GeographicalInformationSystem,GIS)的耦合等问题。作者通过研究,认为上述问题已基本得到解决．从而可以弥补GIS中环境模拟功能的不足,可使EIS纳入GIS的信息空间管理系统,进行信息空间管理、应用分析和信息叠加,并使信息可视化。文章最后指出．目前,可建立GIS-EIS联合系统,以实现信息互换和信息资源的二次开发、利用。
