Development of a risk measure as a sustainable project selection criterion

SUMMARY

Sustainable decision-making requires consideration of technology, ecology, and the social and political infrastructure of society. While it may never be possible to identify with certainty what is sustainable and what is not, an attempt has been made in this paper to formulate a measure that permits one to compare the performances of project alternatives with respect to risk. An algorithm is presented for the evaluation of a risk criterion that can be used with other criteria in the process of selecting project alternatives. The intent of the risk criterion is to involve project stakeholders in the process of quantifying the risks associated with different project alternatives.     

Prioritization of applicable drivers for green supply chain management implementation toward sustainability in Thailand

ABSTRACT

It is essential that the green supply chain management (GSCM) implementation is effectively supported by several strategic drivers for successful implementation and sustainability, especially for the ‘green’ start-ups with a sustainability-driven organizational strategy. This study aims to determine and prioritize the applicable drivers for GSCM implementation of sustainable development strategies in the electronics industry in Thailand. The applicable drivers and their priorities are obtained by applying the fuzzy group decision-making approaches including fuzzy Delphi and fuzzy Analytic Hierarchy Process, based on Thai experts’ perspectives. In this study, three prominent organizational theories, resource-based view, relational view, and institutional theory, are needed to explain the drivers of sustainability and to develop a hierarchical model for prioritization of the drivers. Finally, based on the findings of this study, several recommendations are made that may help to improve the sustainable development in Thailand through more effective implementation of GSCM.

Practical application of sustainable development in decision-making processes in the Great Lakes Basin

SUMMARY

Sustainable development has become the conceptual framework within which societal, economic and environmental issues are addressed at every level around the world. In 1993, a United States-Canada assembly of more than 250 Great Lakes leaders was convened to evaluate the efficacy of creative processes under way in the Great Lakes Basin relative to sustainable development and to identify key success factors and process characteristics which are consistent with principles of sustainable development. A combination of eight criteria for effective project management (i.e. stakeholder involvement; leadership; information and interpretation; planning; human resource development; results and indicators; review and feedback; stakeholder satisfaction) and six principles of sustainable development (i.e. long-range planning and intergenerational responsibility; carrying capacity; anticipation and prevention; full cost accounting; integration of economic, social and environmental factors; efficiency, innovation and continuous improvement) were developed to evaluate and help improve decision-making processes. Such criteria and principles may be useful in improving decision-making processes in other parts of the world.

Theorising pathways to sustainability

Using a Pathways approach, controversies over environmental and natural resource management are viewed as expressions of alternative, or competing, pathways to sustainability. This supports deeper understanding of the underlying causes of natural resource management controversies. The framework is composed of two elements: the STEPS (Social, Technological, and Environmental Pathways to Sustainability) Pathways approach and frame analysis. Many sustainable development dilemmas are played out in specific places and consequently, the Pathways approach is integrated with a place-based frame analysis. The resulting framework guides empirical investigation in place-based contexts. This theorising about sustainability science can be used to cast light on contested natural resource management issues, in this case mining in northern Sweden. By exposing the range of alternative Pathways to critical norms of sustainable development, we ascertain whether action alternatives are compatible with sustainable futures. The framework provides a way in which sustainability science can better understand the origins of natural resource management conflicts, characterise the positions of the actors involved, identify the potential for cooperation between stakeholders leading to policy resolution and judge what Pathways help or hinder the pursuit of sustainable development. In addition, it can enhance sustainability science by guiding integrative sustainability research at the project scale.     

Technological pluralism and diversity as fundamental prerequisites for sustainability

SUMMARY

A definition of technological pluralism and diversity is presented, together with a concept of viability, within the context of sustainable development. The existing contrast with technological homogeneity is also discussed in order to show that the former concept is a necessary prerequisite for the pursuit of sustainability, whereas the latter has led to a process of cultural homogenisation, with the generally acknowledged repercussions for past and present forms of development. The availability of a number of different viable options can be considered a fundamental prerequisite for the most appropriate choice to be made by both producers and consumers; whereas, if only one technical solution is available and ready to be implemented (or requires only marginal modifications), then producers from the various socioeconomic sectors are obliged to implement that solution. This may sometimes have its advantages but very often will have serious drawbacks which may well impede the pursuit of sustainability.

The question of the current form of product diversification is also analysed to see whether it may be advantageous within a sustainable society, and to discover if there is any contrast between this type of diversification and technological pluralism/diversity, and how this contrast may be overcome.     

Towards an understanding of the influence of sustainability culture on the accounting profession

While some previous research has critiqued accounting behaviour towards society and the environment, this paper points in a slightly different direction. With the aid of a chronological chart, it uses sustainability initiatives from the Canadian Institute of Chartered Accountants (CICA) to demonstrate the accounting profession's positive response to societal sustainability culture. Applying the cultural theories of Gray and Hofstede, it argues that society is responsible for alleged negative behaviour in accounting and that society hampers progress in sustainability accounting through political and corporate manoeuvrings. It asserts that, at least within the Canadian context, the more society embraces deeper green culture, the more accounting will transform towards sustainability values. It provides a future research agenda towards extenuating accounting criticisms. The paper suggests some policy implications for government and highlights that the power to condition and moderate accounting behaviour resides within society, governments and the laws of nations; it follows therefore that attaining any goals in sustainable development depends on the choice and commitment of governments and institutions.     

工业废弃地再开发的可持续性评价方法回顾

可持续发展取得共识后,可持续性评价工具大量出现,工业废弃地再开发中也广泛应用.根据对可持续性理解的不同,工业废弃地再开发的可持续性评价方法可以分为目标驱动型和过程驱动型两大类型:目标驱动型往往扩展为"目标-指标评价法",而且根据目标的差异,可以分为单项和综合方法,后者可分为制度性和参与性框架,参与性框架又可以分为自上而下型和自下而上型;过程驱动型包括SEA驱动型和EIA驱动型,前者往往与相关的土地规划有关,后者通常以项目为基础.总之,工业废弃地再开发可持续性评价方法的演进与其基础理论演变和社会变化有密切关系,一方面日益与开发和决策过程相结合,另一方面也更加关注公共参与.借鉴各国工业废弃地可持续再开发的经验,把握可持续性评价的发展趋势,将促进我国城市土地资源的可持续利用,有利于构建"资源集约型"、"环境友好型"的循环型社会.     

Relationships of the dimensions of sustainability as measured by the sustainable society index framework

This article presents a study of the interrelationships between the different dimensions of sustainability as measured by the sustainable society index framework. We examine the statistical relationships between the four indices making up the sustainable society index framework. The analysis uses the complete existing data set provided by Sustainable Society Foundation for the years 2006, 2008, 2010 and 2012 and for 151 countries. While the time period where data are available is quite short, we can make some preliminary observations about the apparent trends in the interrelationships of the different dimensions of sustainability. This study shows that the three dimensions of sustainability are far from all being synergic and positively correlated. There is a strong negative correlation between human well-being and environmental well-being. This is problematic from the point of view of the Brundtland Commission’s three-pillar definition of sustainability. However, the trade-off relationship between economic and environmental development measured by the economic well-being index and environmental well-being index is decreasing and the dimensions are becoming more de-linked. This trend is promising from the sustainability perspective.     

Perceived importance of sustainability dimensions in the Portuguese metal industry

The growing interest of stakeholders regarding the contribution of organizations to Sustainable Development is influencing organizational behavior and strategic planning. The purpose of the present paper is to analyze the perception of the importance of organizational sustainability dimensions in a relevant economic sector: the metal industry. Survey data was collected from a sample of 211 Portuguese industries, and non-parametric statistical tests were used to validate five research hypotheses regarding the importance of the economic, environmental, social and cultural dimensions of sustainability. The results obtained demonstrate awareness of the sampled industries regarding all sustainability dimensions, recognizing that their importance has been increasing over the years, and prospecting that this importance will continue to increase in the future. The industries in this sample revealed different degrees of perceived importance for the different sustainability dimensions: the highest importance was given to the economic dimension, and culture was considered the least important sustainability dimension. However, the perception of the respondents is that these differences will be less relevant in the future. The results also show that companies with certified management systems reveal a higher perceived importance regarding sustainability dimensions. Also, industries with higher values of annual turnover, number of employees and export sales tend to give higher degrees of importance to sustainability dimensions. Considering the economic, environmental and social impacts of metal industries at an international level, the awareness of this industrial sector regarding the importance of sustainability is a relevant step to the commitment towards Sustainable Development.     

组织残留法在水生生物基准中的应用概述

水生生物基准已成为生态风险评价和水环境管理的主要参考依据,在水污染治理、控制和管理以及水生生物保护方面发挥着重要作用。环境和生物学参数对基于水体或沉积物等外暴露浓度的毒性阈值和环境基准存在影响,使其具有变异性和不确定性。而基于组织残留的毒性剂量指标可以减少毒性值的变异性以及不确定性,特别是对于生物累积性物质而言,在毒性效应及环境基准研究中存在显著优势。针对组织残留法在水生生物基准研究中的应用,对组织残留法的概念、优势、应用,以及组织残留基准的推导方法等几个方面进行了综述,并提出了组织残留法在应用中存在的关键问题及建议,旨在推动环境基准、生态风险评价理论和方法的研究,以及为水环境管理和污染防治提供技术支持。     

Assessing aquaculture sustainability: a comparative methodology

Little work dealing with the evaluation of aquaculture system sustainability has so far been undertaken on a global and comparative basis. Moreover, such work is mostly based on very unbalanced approaches in terms of the dimensions of sustainable development that are taken into account. The approach adopted in this article is designed to encompass all the dimensions of sustainability including the institutional one (governance). The taking into account of this latter, in particular, together with the role played by aquaculture in sustainability at the territorial level gives the approach its original and innovative nature. The process of establishing the checklist of sustainability indicators in aquaculture relies on a hierarchical nesting approach which makes it possible to link indicators with general sustainability criteria and principles. At once multidisciplinary and participatory, the approach compares several countries with highly differentiated types of aquaculture system. An original finding from this work is that the technically most intensive farming model scores better than more extensive systems, which might have been thought to be closer to natural systems in their environmental dimension and therefore intuitively more ‘sustainable’. This result suggests relating sustainability outcomes to the level of control and of devolved responsibilities.     

Sustainability indicators for environmental performance and sustainability assessment of the productions of four fine Italian wines

Increased awareness of the importance of environmental protection and the introduction of international standards like ISO 14001 stimulated development of environmental sustainability indicators as a means to measure systems environmental performance. Here, a thermodynamic approach, emergy analysis (Odum, 1988) was used to obtain sustainability indicators able to analyse and quantify the productive and ecological performance of four famous Italian wine productions: Chianti, Brunello di Montalcino, Nobile di Montepulciano, and Barbera d'hti. The application to agricultural production was motivated by the growing need for productive and environmentally sound development in modern agriculture, in which the resource base, the environment, is preserved. The choice of wines, more precisely, grape production, is due to their importance for Italian agriculture and the economy. All the wines demonstrated a good long-term environmental sustainability, especially in view of their high quality and in comparison with the average Italian wine production. Emergy analysis proved a powerful tool for assessing environmental performance of these systems, and its use could easily be extended to other wine productions to obtain a form of environmental performance classification of this product. Systematic use of emergy analysis to assess environmental performance of different processes and products, not necessarily in agriculture, could be useful for environmental certification.     

EMERGY analysis for sustainability evaluation of the Baiyangdian wetland ecosystem in China

This study presents a quantitative and ecological benefit evaluation of the Baiyangdian wetland in China between the years 2000 and 2006. Methods of EMERGY analysis were applied to illustrate the wetland ecosystem, to evaluate the economic and environmental inputs and consequent yields, and to assess the sustainability of the Baiyangdian wetland. The indicators for the integrated ecological and economic system, such as EMERGY yield ratio (EYR) (7.51), EMERGY investment ratio (EIR) (4.52), environmental loading ratio (ELR) (2.92), EMERGY exchange ratio (0.41), and EMERGY sustainable indicator (ESI) (2.57) were calculated, compared, analyzed, and discussed. The non-renewable investment in Baiyangdian was greater than renewable investment, leading to the unsustainable development of the system. High EYR indicated that the Baiyangdian integrated system had created huge profits for its people, while ELR and ESI revealed that human behavior has been a heavy burden on the environment, and countermeasures should be taken by the Chinese government to relieve and resolve these problems. Potential management methods were also proposed in this paper.     

A simulation model to explore the relative value of stock enhancement versus harvest regulations for fishery sustainability

Harvest restrictions and stock enhancement are commonly proposed management responses for sustaining degraded fisheries, but comparisons of their relative effectiveness have seldom been considered prior to making policy choices. We built a population model that incorporated both size-dependent harvest restrictions and stock enhancement contributions to explore trade-offs between minimum length limits and stock enhancement for improving population sustainability and fishery metrics (e.g., catch). We used a Murray cod Maccullochella peelii peelii population as a test case, and the model incorporated density-dependent recruitment processes for both hatchery and wild fish. We estimated the spawning potential ratio (SPR) and fishery metrics (e.g., angler catch) across a range of minimum length limits and stocking rates. Model estimates showed that increased minimum length limits were much more effective than stock enhancement for increasing SPR and angler catches in exploited populations, but length limits resulted in reduced harvest. Stocking was predicted to significantly increase total recruitment, population sustainability, and fishery metrics only in systems where natural reproduction had been greatly reduced via habitat loss, fishing mortality was high, or both. If angler fishing effort increased with increased fish abundance from stocking efforts, fishing mortality was predicted to increase and reduce the benefits realized from stocking. The model also indicated that benefits from stock enhancement would be reduced if reproductive efficiency of hatchery-origin fish was compromised. The simulations indicated that stock enhancement was a less effective method to improve fishery sustainability than measures designed to reduce fishing mortality (e.g., length limits).     

Principal sustainability components: empirical analysis of synergies between the three pillars of sustainability

Starting from the concept of three fundamental sustainability dimensions (environmental, social, and economic), this study investigated professional contributions to sustainability by means of principal component analysis (PCA). Graduates from the Environmental Sciences program (N?=?542) at ETH Zurich described their best professional contributions to sustainable development. Next, they evaluated whether their best practice example contributed to achieving any of the five environmental, social, and economic objectives of the Swiss national sustainability strategy. These judgments served as the basis for a PCA aiming to identify principal sustainability components (PSCs) covering typical synergies between sustainability objectives within and transcending the three fundamental dimensions. Three PSCs capturing important synergies were identified. PSC 1 Product and Process Development reflects how ecological innovation and modernization can generate social and economic benefits and at the same time facilitate the reduction in use of as well as the responsible use of natural resources. PSC 2 Education and Social Economics reflects how educational activities and sociocultural sustainability initiatives can simultaneously promote income and employment, social and human capital, and free personal development. PSC 3 Protection of Nature and Humans covers the synergetic benefits which protection of natural spaces and biodiversity and the reduction of environmental risks have for the protection of health and safety of the population. The study also revealed that integration of environmental, social, and economic aspects is often connected to conflicts between these dimensions. However, contributions which consider the economic situation of future generations or enhance social and human capital achieved considerable integration but showed no inclination toward such conflicts.     

Ecological processes and sustainability

SUMMARY

Ecology has developed from its position as an obscure science to being at the interface of science and public policy. The impact of mankind can be described in ecological terms relating to population size, energy use and non-renewability. Sustainable development needs to be addressed on the basis of knowledge of ecological processes which maintain the environment in a state of change; the processes need to be conserved, not maintained in any particular state. Recent advances in the understanding of ecological processes are reviewed to highlight the potential contribution of this knowledge to the development of a sustainable policy. At the level of the population the significance of considering the extinction risks in the framework of spatio-temporal dynamics is now established indicating opportunities for planning land use more precisely to sustain biodiversity. Whilst the maintenance of habitats is generally the key to the persistence of biodiversity, they must be viewed as ever-changing mosaics within which cycles of succession, best described by Markovian sets of probabilities, are occurring continually. The extent to which these probabilities are distorted will determine whether the ecosystem returns to the same system or moves to a novel one. At the global level, biogeochemical cycles have a certain flexibility in relation to fluxes and stocks, hence pollution must be defined by relating the flow rate of the substance to this flexibility, which often permits the accommodation of anthropogenic perturbations. Non-sustainable processes can be defined in ecological terms, thus providing functional definitions of a sustainable policy and of sustainable development.     

湿地水环境可持续性概念辨析

20世纪60年代以来,随着全球性的生态与资源危机的不断出现,使得人们不得不开始检讨传统的经济发展观,寻求探索新的发展模式。20世纪80年代初期,由联合国环境与发展委员会提出的可持续发展理论,得到了世界各国的普遍认同。然而,从1992年的巴西里约热内卢到2002年的南非约翰内斯堡,可持续发展在这十年间遭遇到理论与实验的双重＂困境＂。2001年,23名世界著名学者在美国《科学》上发表了《可持续性科学》的论文,想用这样一个严格的科学定义来替代意义分歧的可持续发展,避免可持续发展走入歧途。从此,人们越来越频繁地使用＂可持续性＂一词,但怎么实现可持续性则众说不一。学术界对＂可持续性＂和＂可持续发展＂概念的讨论也非常活跃且一直没有间断过。在此,从＂可持续性＂的历史成因出发,分析其在生物学、生态学及环境学等方面的含义,探讨＂可持续性＂一词在湿地水环境这一具体领域的应用,提出＂湿地水环境可持续性＂这一概念,并深入分析其内涵和主要特征,为后续湿地水环境可持续性度量作理论铺垫。
