After its infant stage, a new science usually starts reflexing on its identity and theoretical roots. Sustainability science is not an exception, and the needs of self-reflection are even more pressing because of its inter- and trans-disciplinary characters, which involve a plenty of different approaches, theories and practices. In fact, such a variety does not provide a consistent ground for its future development. Without a solid grounding on a reliable base, the plethora of different theories that currently crowds its arena could in the near future produce a rejection from disciplinary specialized researchers, thus confining sustainability science to a scientific fad. Convincing theoretical roots can be found in systems science and cybernetics, and in particular second-order cybernetics, once amended from autopoiesis theory and radical constructivism, which raise serious doubts of validity and applicability. If sustainability science acknowledged its systemic and cybernetic nature and adopted second-order cybernetics in its amended version, it would gain a powerful reference paradigm and a theoretical common denominator and language to support its researchers and facilitate their knowledge exchange. From their part, systems science and cybernetics would be better understood and embraced as powerful sources of knowledge for understanding modern challenging problems, and second-order cybernetics, after decades of scarce relevance for other scientific disciplines, would be revitalized and would finally evolve adequately in a promising science and social practice.  相似文献

In sustainability science (SS), it is difficult to identify what needs to be solved, and it is also not clear how to solve the problems that are identified. There has been no consensus on the underlying question of “What is structuring knowledge in SS?” This paper focuses on knowledge structuring accompanied by supporting of thinking. It addresses the key challenges associated with knowledge structuring in SS, identifies the requirements for the structuring of knowledge, proposes a reference model, and develops an ontology-based mapping tool as a solution to one layer of the reference model. First, we identify the important requirements for SS knowledge structuring. Second, we develop a reference model composed of five layers based on three of the requirements. Third, we develop an ontology-based mapping tool at Layer 2 of the reference model for meeting the two major challenges for SS, namely, identifying what problems should be addressed in SS itself and proposing solutions for those problems. The tool is designed to store and retrieve information regarding SS, to provide access to a prototype ontology for SS, and to create multiple maps of conceptual chains depending on a user’s interests and perspectives. Finally, we assess whether the developed tool successfully realizes the targeted part of the reference model for SS by examining the tool’s conformity to the reference model, as well as its usability, effectiveness, and constraints. Although several issues were identified in the prototype ontology and the mapping tool, the study concluded that the mapping tool is useful enough to facilitate the function of Layer 2. In particular, the mapping tool can support thinking about SS from the viewpoint of: (a) finding new potentials and risks of technological countermeasures studied in SS; (b) helping users to get a more comprehensive picture of problems and their potential solutions; and (c) providing an effective opportunity to come up with new ideas that might not be thought of without such a tool.  相似文献

One of the most important and yet difficult challenges that modern societies face is how to mobilize science and technology (S&T) to minimize the impact of human activities on the Earth’s life support systems. As the establishment of inter-disciplinary education programs is necessary to design a unified vision towards understanding the complexity of human nature, the Research Institute for Sustainability Science (RISS) launched a new program on sustainability science in April 2008. The program expects to address the issue of how to use knowledge more effectively to understand the dynamic interactions between nature and human society. This paper first offers an overview of international and Japanese initiatives on sustainability education in which we highlight the uniqueness of the attempt by the Integrated Research System for Sustainability Science (IR3S). The paper then introduces the RISS program for sustainability science, addressing the principles and curriculum design of the program. The paper discusses the main problems and constraints faced when developing the program, such as institutional barriers in building a curriculum and obtaining cooperation from faculty. To challenge these barriers and limitations, the RISS uses the program as a platform to disseminate the idea of sustainability science across the university. This attempt helps us to obtain the continuing cooperation necessary to improve and maintain the program.

Research core and framework of sustainability science   总被引:2,自引:6,他引:2  
This paper reviews recent achievements in sustainability science and discusses the research core and framework of sustainability science. We analyze and organize papers published in three selected core journals of sustainability science: Sustainability Science, Proceedings of the National Academy of Sciences of the United States of America, and Sustainability: Science, Practice, & Policy. Papers are organized into three categories: sustainability and its definition, domain-oriented research, and a research framework for sustainability science. First, we provide a short history and define the basic characteristics of sustainability; then we review current efforts in the following research domains: climate, biodiversity, agriculture, fishery, forestry, energy and resources, water, economic development, health, and lifestyle. Finally, we propose a research framework for sustainability science that includes the following components: goal setting, indicator setting, indicator measurement, causal chain analysis, forecasting, backcasting, and problem–solution chain analysis. We emphasize the importance of this last component for improving situations and attaining goals.  相似文献

The most important driver for management is successful business that increases its value to shareholders. The adoption of environmentally responsible business practices can open up an additional range of opportunities for companies, for example by improving material efficiency. The choice to improve environmental performance of a company tends to also improve its financial performance. In this paper, our aim is to study the value of sustainability in process and mining industry from the perspective of interest groups such as investors, customers and the public, by using case examples. Interviews and workshops were employed to investigate whether or not investors and customers are interested in sustainability in the process and mining industries. We also illustrate how easy it can be to jeopardize corporate reputation through. The present situation and challenges faced in bringing sustainability into everyday business practices are summarized and proposals made concerning ways to achieve increased sustainability.  相似文献

The role of energy in the present world is critical in terms of both economical development and environmental impact. Renewable energy sources are considered essential in addressing these challenges. As a result, a growing number of organisations have been adopting hybrid renewable energy system (HRES) to reduce their environmental impact and sometimes take advantage of various incentives. When a HRES is being planned, the ability to model a HRES can provide an organisation with numerous benefits including the capability of optimising sub-systems, predicting performances and carrying out sensitivity analysis. In this paper, we present a comprehensive system dynamics model of HRES and combined heating and power (CHP) generator. Data from a manufacturing company using HRES and CHP generator are used to validate the model and discuss important findings. The results illustrate that the components of a HRES can have conflicting effects on cost and environmental benefits; thus, there is a need for an organisation to make trade-off decisions. The model can be a platform to further simulate and study the composition and operating strategies of organisations that are venturing to adopt new or additional HRESs.  相似文献

Sustainability is achieved only when there is full reconciliation between: (1) economic development; (2) meeting, on an equitable basis, growing and changing human needs and aspirations; and (3) conserving the limited natural resources and the capacity of the environment to absorb the mulitple stresses that are a consequence of human activities. The linkages between climate and sustainability are examined in the context of both the wider Asia-Pacific region and local level climate risks and adaptation responses. These findings are used to underpin and illustrate several implications for sustainability science. Climate change is seen as both an impediment to increasing sustainability and as an opportunity, though in most cases the former far outweighs the latter. Assessments of climate change vulnerability and risk are shown to be of critical importance because they inform decisions as to where resources for adaptation are best invested. They also show whether global efforts to reduce greenhouse gas emissions need to be strengthened because of limits to adaptation. In practice, adaptation takes place at many levels, essentially ranging between tangible interventions at community and enterprise level and national and international efforts to strengthen the enabling environment for adaptation. It is informative to undertake regional assessments of adaptation, even though most adaptation interventions need to reflect local conditions, including local adaptive capacities. The foregoing findings, based in part on a series of regional and local case studies, lead to several recommendations for further research that will help reduce barriers to implementing responses that reduce climate related risks, including adverse consequences for sustainability. The recommendations relate to such themes as making optimum use of predictive capabilities, characterising the linkages between climate change and sustainability, implications of the required rates and magnitudes of adaptation, institutional responses that enhance adaptive capacity, use of new and traditional technologies, the multiple dimensions of social responsibility, and enhancing the enabling environment for adaptation at the community and enterprise level. If these recommendations are acted upon they will, in turn, help address much needed improvements in quantifying the costs and benefits of adaptation, prioritising adaptation options, assessing sustainable development tradeoffs, and monitoring the success of adaptation initiatives. Such improvements will have even greater utility if they are incorporated into user-friendly decision support tools for adaptation.  相似文献

Improvements in remote sensing technologies and the use of geographic information system (GIS), are increasingly allowing us to develop indicators that can be used to monitor and assess ecosystem condition and change at multiple scales. This paper presents global- and regional-level indicators developed by the World Resources Institute and collaborating partners using remote sensing and GIS. Presented as regional and global maps, these spatial indicators are ideal communication tools to raise awareness of the condition of the Earths ecosystems among different audiences. Global and regional spatial indicators not only inform us about the current condition of, and pressures on, ecosystems, but also about the likely capacity of the ecosystem to continue to provide goods and services to future generations. The increasing focus on integrating socio-economic and biological information with remote sensing and GIS technology can only help to further our understanding and capacity to manage ecosystems in a more sustainable manner.The author researched and wrote this paper while working for the World Resources Institute (WRI).  相似文献

This paper captures the lessons learned from the implementation of water supply and sanitation interventions in Mayiwane community in the rural northeastern region of the Kingdom of Swaziland, relating to water system rehabilitation, water quantity and quality improvements, and the promotion of latrine construction. The issues examined include both the dimensions of implementation efficiency and project effectiveness: first identifying the inputs, activities and final outputs and, then, tracking the entire project cycle, from design to implementation and monitoring. To draw meaningful lessons for the sustainability of similar interventions, project evaluation involved extensive fieldwork, water sampling and testing, review of documentation, and interviews with community members and officials of governmental, civil society and collaborating external agencies.

ABSTRACT

Public discourse frequently cites the damaging activities of large organisations on global environmental issues, but smaller organisations are rarely, if ever, featured. Small and Medium Enterprises (SMEs) make up 99% of all businesses in the EU, cumulatively causing more industrial pollution and producing more waste than larger businesses. However, large companies are more likely to address sustainability issues than smaller ones. SMEs need help to change. In a collaborative approach, an online sustainability framework was developed to overcome the barriers contributing to the slow uptake in environmental management in SMEs. The views of owner-managers were incorporated throughout the development process. Best practice environmental tools and training were identified, which were designed in an SME-friendly way and made available online. This paper describes the development of the pilot Sustainability and Eco-Innovation (SEco) toolkit, followed by an analysis of its use. This research finds that a self-led toolkit was not enough to nudge SMEs to address environmental issues, despite being approved by owner-managers at each step.  相似文献

This paper recognises the need for a revision of watershed development policy in India in relation to the planning of development interventions involving agricultural intensification and rainwater harvesting and the need for new approaches to assist the planning process. Building on, and using as an example, the results of biophysical and societal impact studies carried out on two watershed development projects in Karnataka three new management/dissemination tools, are suggested. These are (1) the web-based geographical information systems exploratory, climate land assessment and impact management tool dissemination tool for disseminating to policymakers and non-specialist stakeholders the downstream impacts of watershed interventions, (2) the ‘quadrant’ approach for ensuring that sustainability criteria are met and (3) Bayesian networks to investigate the biophysical and societal impacts of interventions.

Sustainable agricultural development is a necessity for sustainable economic growth and social development in Africa. Sustainable agriculture largely depends on how effective natural and environmental resources are managed and utilized; it also depends on the security of continuous access to such resources. This research was aimed to look into trends in agricultural productivity, examine the persistence of the environmental insecurity, analyze the relationship between the two, and explore their links to the national development policies. The results are discussed in the context of relevance to national development policies and their implications on the sustainability of agriculture and rural livelihoods security. Literature survey, records collection from the stakeholders, village level participatory assessments (PAs), observations and questionnaire survey were tools used for data collection. The study shows significant (P < 0.01) declines in cereal crop yields, cattle milk yield and cattle calving rate, and increasing cattle mortality rate. Elements of environmental insecurity were found to account for decline in agricultural productivity; significant (P < 0.01) proportion (68%), of 266 households interviewed, reported land resources deterioration, declining soil fertility, and increasing drought frequencies as the causes of their low productivity. Declined fertilizer consumption and increasing variability in rainfall amount significantly (P < 0.01) accounted for 59% and 39%, respectively, of the variations observed in total annual production of rice and maize, which are major cereals in the study area. This study recommends measures to improve soil productivity such as improved fertilizer application and use of organic manures along with mineral fertilizers for maintaining soil productivity; education of farmers on sustainable use and management of land resources; and pro-poor rural policies in agricultural development and environmental governance.

The past decade has seen important changes in the approach to water management issues in the Netherlands. Urban development, recreational demands, agriculture, nature conservation and other space demanding functions compete with water management objectives in their claims for space. An analysis of some recent water management projects illustrates that the implementation of the new water management approach is not always easy. Catchment-based multifunctional projects encounter major constraints. These constraints are: 1) national goals versus local constraints; 2) limited sense of urgency; 3) lack of institutional coordination in the water management community; 4) unclear views over nature conservation, and; 5) limited understanding of wetland functioning in relation to flood risk management. We promote platforms for collaborative planning as a way to improve stakeholder participation in early stages of decision-making. Negotiation and mediation support tools can enable stakeholders and mediators to formulate the problems that need to be addressed more effectively. Early involvement of stakeholders in the planning process is almost a condition for successful implementation; however, it is no guarantee of success, and not all conflicts can be solved. Therefore assessment of the costs and benefits of different parties is important for compensation schemes to gain broad social acceptance.  相似文献

Vegetables grown with phosphate fertilizer (conventional management), with bovine manure fertilization (organic management) and in a mineral nutrient solution (hydroponic) were analyzed and the concentrations of 238U, 226Ra and 228Ra in lettuce, carrots, and beans were compared. Lettuce from hydroponic farming system showed the lowest concentration of radionuclides 0.51 for 226Ra, 0.55 for 228Ra and 0.24 for 238U (Bq kg−1 dry). Vegetables from organically and conventionally grown farming systems showed no differences in the concentration of radium and uranium. Relationships between uranium content in plants and exchangeable Ca and Mg in soil were found, whereas Ra in vegetables was inversely correlated to the cation exchange capacity of soil, leading to the assumption that by supplying carbonate and cations to soil, liming may cause an increase of U and a decrease of radium uptake by plants. The soil to plant transfer varied from 10−4 to 10−2 for 238U and from 10−2 to 10−1 for 228Ra.  相似文献

This paper utilizes an inclusive community based sustainability framework with a focus on a resort destination in providing a potential model for more inclusive long-range destination planning and implementation. Four diverse, but interrelated areas of sustainable tourism were specified in this framework for a more comprehensive process including ecological, cultural, economic and socio-community sustainability. In addition a strategic community driven structure, which provides direction, information and practices, serves the purpose of integrating and implementing the framework. The unique tourism destination, Noosa in Australia is used as an example of embracing sustainable tourism as a community and as part of a larger focus on the four key components of sustainability. By viewing sustainable community attributes as assets, all of which are important to manage, enhance and/or conserve, it is expected that the resort community will continue to attract visitors to feel connected and committed to experiencing its lifestyle, sense-of-community and natural features while also contributing to community sustainable stewardship and a strong tourism economy.

Closed systems are governed by the second law of thermodynamics and cannot spontaneously become more ordered. In open physical systems exposed to external energy flows, additional macroscopic degrees of freedom (memory cells) emerge, their number increasing with an increase in the flow and orderliness of the external energy. Biological systems are characterized by molecular degrees of freedom, the density of which is more than twenty orders of magnitude higher than that of macroscopic degrees of freedom in any open physical system exposed to the same external energy flow. This indicates that the self-organization of physical systems in external energy flows and the self-organization and evolution of living systems are fundamentally different. Thus, although life is an open system, the energy (food) flows that it consumes and all other external factors affecting life are so poorly ordered, compared to life itself, that they cannot increase the degree of order in the latter. Therefore, living systems obey an analogue of the second law of thermodynamics: within periods of time considerably shorter than the duration of evolutionary changes, living systems can only lose the accumulated information (i.e., the entropy can only increase), even if the systems consume external energy–food flows.  相似文献

Food production has to be increased in a sustainable way to meet the future global demand. A key position is attributed to developing countries. A deepened understanding of their agricultural regions with specific resource endowments and constraints is therefore crucial. In this study we propose a methodology based on material flux analysis (MFA) to assess the resource potentials and limitations of a Nicaraguan agricultural region. We focus on current regional and farm resource management and explore them under two scenarios. Indicators are nitrogen and the degrees of self-sufficiency (DSS) for energy, and the staples maize and beans. As data is scarce, most information is based on interviews with farmers of four categories and key persons, and on literature. The results show that nitrogen management does not differ considerably among categories. Nitrogen is mined mostly from staple plots. Self-sufficiency for beans is given in an average year. Yet, landless and small farmers neither produce enough maize for autoconsumption, nor are they self-sufficient for firewood. Energy supply is also the core problem of the region, since the DSS is 70%. Soil nitrogen stocks last at most for three more generations. Analyses with the scenario technique show that: (a) Unlimited population growth has serious consequences in the near future e.g. severe shortage of energy and food. (b) Alternative farming systems are possible, but they require reducing the population by a factor 2, and thus the creation of jobs in a Hinterland.

Assessment of the environmental and radiological consequences of a nuclear accident requires the management of a great deal of data and information as well as the use of predictive models. Computerised Decision Support Systems (CDSS) are essential tools for this kind of complex assessment and for assisting experts with a rational decision process. The present work focuses on the assessment of the main features of selected state-of-the-art CDSS for off-site management of freshwater ecosystems contaminated by radionuclides. This study involved both developers and end-users of the assessed CDSS and was based on practical customisation exercises, installation and application of the decision systems. Potential end-users can benefit from the availability of several ready-to-use CDSS that allow one to run different kinds of models aimed at predicting the behaviour of radionuclides in aquatic ecosystems, evaluating doses to humans, assessing the effectiveness of different kinds of environmental management interventions and ranking these interventions, accounting for their social, economic and environmental impacts. As a result of the present assessment, the importance of CDSS “integration” became apparent: in many circumstances, different CDSS can be used as complementary tools for the decision-making process. The results of this assessment can also be useful for the future development and improvement of the CDSS.  相似文献

生态流量制度是流域生态环境保护的重要制度保障,是水资源、水环境、水生态“三位一体”保障体系的重要组成部分,是满足水生态承载能力刚性约束的制度体现。目前,水资源开发利用以及水环境污染防治由《水法》以及《水污染防治法》做出了全面规定,而保障水生态功能实现的生态流量则作为水电工程环境影响评价制度的一个因子予以考量,这显然无法达成“维持水体生态功能”之目标。生态流量制度作为保护水生态功能的独立法律制度,应当在涉水立法中予以明确,同时形成完整的生态流量制度体系。基于此,本文对生态流量在立法中的法律表达提出制度建议,包括:①生态流量底线是为了满足流域及其周边区域原有生态系统功能所需要的水流数量以及水文过程的最低要求。生态流量底线制度包括生态流量底线的划定、生态流量监测以及生态流量底线的适应性管理。②流域生态流量协议,是在生态流量底线之上企业与政府达成的更高标准的生态流量约束,是企业与政府合作进行生态环境治理的新模式;是政府、企业、社会共同保障水生态的制度体现;它在公众参与的基础上形成流域规则嵌套,通过绿色水电认证提高企业落实的积极性。③生态流量法律责任制度依据生态流量底线和流域生态流量协议为用水主体设置的不同义务,分别规定了不同的法律责任。违反生态流量底线要求且拒不改正的按日连续处罚,体现出督促企业遵守生态流量底线要求的立法目的;仅违反流域生态流量协议而未突破生态流量底线要求的,则追究其违约责任,撤销其已享受的生态环境优惠,体现对其违背契约精神的惩罚。  相似文献
