    It is generally agreed that hydrogen is an ideal energy source, both for transportation and for the generation of electric power. Through the use of fuel cells, hydrogen becomes a high-efficiency carbon-free power source for electromotive transport; with the help of regenerative braking, cars should be able to reach triple the current mileage. Many have visualized a distributed electric supply network with decentralized generation based on fuel cells. Fuel cells can provide high generation efficiencies by overcoming the fundamental thermodynamic limitation imposed by the Carnot cycle. Further, by using the heat energy of the high-temperature fuel cell in co-generation, one can achieve total thermal efficiencies approaching 100 percent, as compared to present-day average power-plant efficiencies of around 35 percent. In addition to reducing CO2 emissions, distributed generation based on fuel cells also eliminates the tremendous release of waste heat into the environment, the need for cooling water, and related limitations on siting. Manufacture of hydrogen remains a key problem, but there are many technical solutions that come into play whenever the cost equations permit . One can visualize both central and local hydrogen production. Initially, reforming of abundant natural gas into mixtures of 80% H2 and 20% CO2 provides a relatively low-emission source of hydrogen. Conventional fossil-fuel plants and nuclear plants can become hydrogen factories using both high-temperature topping cycles and electrolysis of water. Hydro-electric plants can manufacture hydrogen by electrolysis. Later, photovoltaic and wind farms could be set up at favorable locations around the world as hydrogen factories. If perfected, photovoltaic hydrogen production through catalysis would use solar photons most efficiently . For both wind and PV, hydrogen production solves some crucial problems: intermittency of wind and of solar radiation, storage of energy, and use of locations that are not

    The National Ignition Facility (NIF), the world's largest and most energetic laser system, is now operational at Lawrence Livermore National Laboratory (LLNL). The NIF will enable exploration of scientific problems in national strategic security, basic science and fusion energy. One of the early NIF goals centers on achieving laboratory-scale thermonuclear ignition and energy gain, demonstrating the feasibility of laser fusion as a viable source of clean, carbon-free energy. This talk will discuss the precision technology and engineering challenges of building the NIF and those we must overcome to make fusion energy a commercial reality.

    All energy systems have adverse as well as beneficial impacts on the environment. They vary in quality, quantity, in time and in space. Environmentally sensitive energy management tries to minimize the adverse impacts in an equitable manner between different groups in the most cost-effective ways. Many of the enviornmental impacts of energy continue to be externalized. Consequently, these energy systems which can externalize their impacts more easily are favoured, while others remain relatively expensive. The lack of full integration of environmental factors into energy policy and planning is the overriding problem to be resolved before a transition towards sustainable energy futures can take place. The most pressing problem in the developing countries relates to the unsustainable and inefficient use of biomass resources, while in the industrialized countries, the major energy-environment problems arise out of the continued intensive use of fossil fuel resources. Both of these resource issues have their role to play in climate change. Although there has been considerable improvement in pollution control in a number of situations, most of the adverse impacts will undoubtedly increase in the future. Population growth will lead to increased demand, and there will also be greater use of lower grade fuels. Climate change and the crisis in the biomass resource base in the developing countries are the most critical energy-environment issues to be resolved in the immediate future. In both cases, international cooperation is an essential requirement for successful resolution. 26 refs.

    The expression Develop Sustainable of wide use today in day is used among national political leaders and among environmentalists. The sustainable economy from the environmental point of view is that that obeys the basic principles or laws of the sustainability; principles so real as those of the aerodynamic one or those of the thermodynamic. If somebody intends, for example, to design an airplane, it will have to be adjusted to the aerodynamic principles and to print to the apparatus a certain stability degree so that it can fly. In the same way, an economic system environmentally sustainable it must respond to the balance principles if it doesn't want to be condemned to the failure. The fundamental laws or sustainability principles are as rigorous as the aerodynamic laws. The society can violate these laws in the short term; but not long term. As well as an airplane can lose height in a brief lapse without falling; the economy can violate the principles of the sustainability in the short term without collapsing. Among of the sustainability principles figure the following: long term; the extinction of species cannot exceed the evolution of the species; the soil erosion cannot exceed the soils formation; the destruction of forests cannot exceed the regeneration of the forests; the emissions of carbon cannot exceed the fixation of carbon; the fishing cannot exceed the regenerative capacity of the banks of fish and, in the human land, the morbidity cannot exceed the mortality. The author also speaks of the disappearance of species, ozone layer, stability of the climate, earth, water fertilizers and alimentary systems among others

    Nuclear technology offers unique tools in the quest for sustainable development. Such technology is often the best to gather information and provide solutions that would not otherwise be possible or practical: to diagnose and treat disease, to breed better crops and fight insect pests; to assess new sources of fresh water; and to monitor pollution. While many may only think of energy, nuclear technology has a much larger role to play in human development. Where it can make a difference, the International Atomic Energy Agency (IAEA) provides support to 134 Member States for using this technology to solve the important challenges they face. Isotopes, stable and radioactive forms of chemical elements, can be used to 'label' materials under study. Since both stable and radioactive isotopes can be identified and measured using appropriate equipment, labelling is often used in diagnostic medical tests, in studies of underground sources of water, and to trace pollutants, such as heavy metals and pesticides. Stable, non-radioactive, isotopes are used in nutritional studies to trace the metabolism of vitamins and trace minerals in supplements. Other nuclear techniques use radiation which can be focussed into beams and depending on the intensity, can be used to kill cancer cells, to sterilize tissue grafts for burn victims, to sterilize food against insects or disease causing pathogens, to make insects sterile so they cannot reproduce, to induce desirable genetic changes in crops, or to scan body organs for abnormalities

    In the past, material innovation has changed society through new material-induced technologies, adding a new value to society. In the present world, engineers and scientists are expected to invent new materials to solve the global problem of climate change. For the transport sector, the challenge for material engineers is to change the oil-based world into a sustainable world. After witnessing the recent high oil price and its adverse impact on the global economy, it is time to accelerate our efforts towards this change. Industries are tackling global energy issues such as oil and CO2, as well as local environmental problems, such as NO(x) and particulate matter. Hydrogen is the most promising candidate to provide carbon-free, emission-free and oil-free mobility. As such, engineers are working very hard to bring this technology into the real society. This paper describes recent progress of vehicle technologies, as well as hydrogen-storage technologies to extend the cruise range and ensure the easiness of refuelling and requesting material scientists to collaborate with industry to fight against global warming.

    Full Text Available The future of global environmental sustainability is contingent upon educating the next generation of environmental stewards. Critical elements of training such an interdisciplinary workforce include mentoring and experiential learning in the areas of science, communication, and leadership. To keep pace with the ever changing and increasingly complex issues of global environmental sustainability, environmental educators must encourage and support the participation and training of a diverse body of students in the environmental sciences. The Rocky Mountain Sustainability and Science Network (RMSSN is a partnership of over two dozen universities, federal agencies and other organizations designed to help train the next diverse generation of interdisciplinary leaders who are prepared to address issues related to global climate change, environmental sustainability, and the management of public lands and resources using the Rocky Mountains as a laboratory and classroom. Herein, we present the RMSSN as a model for engaging students in the environmental sciences with an emphasis on understanding key elements of sustainability. Our model is based on a foundation of: (1 diversity; (2 tiered mentoring in cohorts; (3 engaging lectures coupled with field experiences on public lands; (4 long term networking; and (5 environmental internships.

    Today we had a visit from Ban Ki-moon, Secretary-General of the United Nations. This is Mr Ban’s second visit to our laboratory, but his first since CERN was granted Observer status at the United Nations General Assembly last December. It therefore gave us our first opportunity to discuss joint initiatives already under way.   Our discussions focused on CERN’s contribution to science-related UN activities, and in particular those of the UN’s Economic and Social Council, ECOSOC, whose focus for 2013 is on leveraging science, technology, innovation and culture for a sustainable future. CERN will be taking part in ECOSOC meetings in Geneva in July, and we will be contributing on the theme of young women in science to ECOSOC’s Youth Forum on 27 March.

    Full Text Available Protected areas in Africa are threatened by a lack of funds to conduct their work effectively and by extremely poor communities that surround their resource-rich areas. We believe that conservation staff suffer from mental blocks. They assume that business and profitability reflect unethical processes that destroy natural resources. We developed a workshop process that allows conservationists to integrate entrepreneurial thinking with conservation principles and ethics. We measured perceptions both before and after such a workshop to assess the impact of the process. The process assisted conservationists at the Southern African Wildlife College to develop the integrated mental frameworks that are required to develop conservation into a sustainable business. The group internalised the new mental framework, whereby conservation and business, when integrated in an ethical manner, are viewed as virtually synonymous. The group also identified many innovative ways in which they could derive sustainable income from their natural resources while simultaneously achieving their conservation objectives.

    1995-01-01

    Alternative paths to the future which might produce true sustainability involve comprehensive behavior change, not only by government and business leaders but also by ordinary citizens. Individual and societal behavior is guided to a great extent by the values and beliefs underlying that behavior. A growing body of literature deals with this subject, which is called environmental ethics. From the seminal work of Thomas Berry to conference proceedings and journal articles, examinations of the moral and ethical implications of the need for changing values and behavior can be found in both the religious and secular literature. Central to much of that literature is the concept of envisioning a sustainable future. Developing, promoting, and publicizing those visions will be important in overcoming the natural fears one has of changing basic values and beliefs, thereby enabling open and public discussion of the need of a set of sustainable values for a livable future

    Full Text Available Eco-innovation is any form of innovation resulting in or aiming at significant and demonstrable progress towards the goal of sustainable development, through reducing impacts on the environment, enhancing resilience to environmental pressures, or achieving a more efficient and responsible use of natural resources. States and governments of the world, different institutions and organizations actively involved and aware in public policies, strategies and actions, reaffirm their commitments and reassess actions in order to achieve a truly sustainable development. In the common vision and the resolutions and other documents of the United Nations Conference on Sustainable Development, Rio+20, the words "environment", "innovation", "green economy" appear very often and almost always along the same context, to achieve the objectives of the sustainable development. The objectives of EU's Europe 2020 strategy for smart, sustainable and inclusive growth, are being implemented through a number of Flagship Initiatives addressing the main challenges, like “Innovation for a sustainable Future - The Eco-innovation Action Plan (EcoAP”. Eco-innovation Observatory developed the Eco-Innovation index, the first tool to assess and illustrate eco-innovation performance across the EU Member States. Like in all fields, in textiles and leather field, eco-innovation is present and there are a lot of tools available that measure environmental damage and help manufacturers and brands become more sustainable. Eco-innovation is not just a trendy concept but a reality and a necessity nowadays, a way to achieve a sustainable future for ourselves and future generations.

    The spectre of change is galvanising debate about the future of the poles. Climatic shifts look set to affect both profoundly. As the ice melts, new marine transport routes will open up. The exploitation of natural resources could expand significantly. Further risks include marine acidification, the migration of commercial fish species and coastal erosion. In the Arctic, traditional livelihoods could suffer. Meanwhile, national claims of sovereignty over areas of ocean floor are fuelling fears of a new 'cold war' over access to mineral resources in sensitive environments. Clearly, science alone cannot address the challenges facing the poles: a coherent strategy for sustainable development is urgently needed.

    The Johannesburg summit, which took place at the end of the summer of 2002, was the opportunity to spread out to the large public worldwide the notion of sustainable development, a notion that remained confidential so far. It was also a good opportunity to show that the share of energy resources is a vital point for the future. The institute of energy and environment of the French-speaking world has published a huge dossier which takes stock of the overall questions raised by the summit and answered by French-speaking experts. This article reprints some large extracts of two contributions devoted to the energy and its key role in the sustainable development. The first contribution deals with the four energy stakes of the sustainable development: the energy and the fight against poverty, the mastery of energy demand, the development of renewable energy sources, and the nuclear question. The second contribution treats of the five points of the action plan of the world energy council (CME) for the implementation of a durable energy policy in developing countries. (J.S.)

    In support of the mission-specific challenges of aeronautics and space exploration, NASA Ames produces a wealth of research and technology advancements with significant relevance to larger issues of planetary sustainability. NASA research on NexGen airspace solutions and its development of autonomous and intelligent technologies will revolutionize both the nation's air transporation systems and have applicability to the low altitude flight economy and to both air and ground transporation, more generally. NASA's understanding of the Earth as a complex of integrated systems contributes to humanity's perception of the sustainability of our home planet. Research at NASA Ames on closed environment life support systems produces directly applicable lessons on energy, water, and resource management in ground-based infrastructure. Moreover, every NASA campus is a 'city'; including an urbanscape and a workplace including scientists, human relations specialists, plumbers, engineers, facility managers, construction trades, transportation managers, software developers, leaders, financial planners, technologists, electricians, students, accountants, and even lawyers. NASA is applying the lessons of our mission-related activities to our urbanscapes and infrastructure, and also anticipates a leadership role in developing future environments for living and working in space.

    2012-06-01

    The IAEA helps its Member States to use nuclear technology for a broad range of applications, from generating electricity to increasing food production, from fighting cancer to managing fresh water resources and protecting the world's seas and oceans. Despite the Fukushima Daiichi accident in March 2011, nuclear power will remain an important option for many countries. Use of nuclear power will continue to grow in the next few decades, although growth will be slower than was anticipated before the accident. The factors contributing to the continuing interest in nuclear power include increasing global demand for energy, as well as concerns about climate change, volatile fossil fuel prices and security of energy supply. It will be difficult for the world to achieve the twin goals of ensuring sustainable energy supplies and curbing greenhouse gases without nuclear power. It is up to each country to choose its optimal energy mix. The IAEA helps countries which opt for nuclear power to use it safely and securely. Every day, millions of people throughout the world benefit from the use of nuclear technology. The IAEA helps to make these benefits available to developing countries through its extensive Technical Cooperation programme. For instance, we provide assistance in areas such as human health (through our Programme of Action for Cancer Therapy), animal health (we were active partners in the successful global campaign to eradicate the deadly cattle disease rinderpest), food, water and the environment. The IAEA contributes to the development of global policies to address the energy, food, water and environmental challenges the world faces. We look forward to helping to make Rio+20 a success. This brochure provides an overview of the many ways in which nuclear technology is contributing to building the future we want.

    In the special session of the General Assembly 1997, UN, the member nations examined the progress of Agenda 21, gave a stress on the energy role to achieve the goal - the sustainable development -, and decided to deal the issues of energy and transportation in the 9th session of Commission on Sustainable Development, UN (CSD-9), which would open in April 2001. To activate the discussion on the sustainable energy, the three associations - UNDP, UBDESA, WEC - played a leading role in preparing 'World Energy Assessment (WEC)'. WEC provided the assessment on the social, economy, environment, and security issues, all of which were related to energy, and proved the compatibility of the sustainable development goal and the various energy options. This report was submitted for the whole process and Rio+10, which was scheduled in the next year, as a non-official data. Goldemberg, the chairman in charge of this report, insisted, 'The present form of the energy production and use is causing the whole global issues, which is very realistic. The imbalance of energy supply cannot be sustainable with the humanitarian, political, and environmental reasons.' The purpose of WEA was to examine the apprehensions and to search the policies to solve them.

    Full Text Available It is clear that the future is not simplysomething already predetermined that we must acceptblindly: rather, it is open and to a large extent determinedby the course of actions we decide to take. For thisreason, we need to look at the future and its uncertaintiesin an articulated fashion, developing specific tools toconsider both how the future might unfold if we do notact and how we might like the future to unfold if actionwere to be taken.As demonstrated on valuable intellectual exercise forlooking into an uncertain future involves the developmentof “scenarios” intended as logical and plausibleconjectures about how fundamental drivers will affectglobal societies, economics, resource use and theenvironment. The literature review shows a multiplicity ofscenarios, conducted as different scales ranging from thenational to the global scale, with different time horizonsand with a focus on different strategic issues.Exploratory scenarios help prepare for events that,without representing a straight-line continuation of pasttrends, are plausible and entirely possible. Exploratoryscenarios can help a lot to accelerate and calibrate theresponse to new developments, as well as providing astrategic framework technology development policy.Normative scenario has, as its goal, the evolution of adesirable future rather than a future inexorably imposedupon us by the inertia of system. Building a normativescenario requires the creators to clearly define thedesirable characteristics of their future, and to expressthis future in terms of measurable targets.The use of such a scenario process lies as much in theissues it requires us to comfort as the precise details isgenerates. The future will not look exactly like the oneenvisioned: other priorities will intercede and nationalconditions and circumstances will dictate the specifics ofthe energy policies that may be adopted.

  14. Sustainable supply chain management: current debate and future directions

    Directory of Open Access Journals (Sweden)

    Bruno Silvestre

    Full Text Available Abstract This paper is a research brief on sustainable supply chain management and covers some of the key elements of literature’s past debate and trends for future directions. It highlights the growth of this research area and reinforces the importance of a full consideration of all three key dimensions of sustainability when managing sustainable supply chains, i.e., the financial, environmental and social dimensions. Therefore, supply chain decision makers need to unequivocally assess the impact of their decisions on the financial, environmental and social performances of their supply chains. This paper also argues that risks and opportunities are the key drivers for supply chain decision makers to adopt sustainability within their operations, and that barriers to sustainability adoption exist. This research highlights that, depending on the focus adopted, supply chains can evolve and shift from more traditional to more sustainable approaches over time. The paper concludes with some promising avenues for future investigation.

    Over the last 50 years Australia has generally maintained adequate energy supplies to its population in an increasingly efficient and sustainable manner It has also been able to help sustain other economies in supplying energy resources of coal, gas and uranium. This provides 20% of Australia's export income, contributing to the quality of life experienced by Australians.Presently the reserve margin in the electricity power system is adequate and, with the exception of oil, ample local energy resources are available. Over the same period the doubling in energy generation efficiency has matched the population growth in NSW The same contributions by technology and population can be expected over the next 50 years. The growth in demand has however increased by a factor of about five.Sensible demand management could reduce this to a more acceptable figure over the next 50 years as shown in two possible scenarios. This, coupled with ongoing energy exports will help sustain the quality of life in this economy

    Current global economic activities are increasingly being perceived as unsustainable. Despite the high number of publications, sustainability science remains highly dispersed over diverse approaches and topics. This article aims to provide a structured overview of sustainability performance evaluation related publications and to document the current state of literature, categorize publications, analyze and link trends, as well as highlight gaps and provide research recommendations. 128 articles between 2007 and 2018 are identified. The results suggest that sustainability performance evaluation models shall be more balanced, suitable criteria and their interrelations shall be well defined and subjectivity of qualitative criteria inherent to sustainability indicators shall be considered. To address this subjectivity, group decision-making techniques and other analytical methods that can deal with uncertainty, conflicting indicators, and linguistic evaluations can be used in future works. By presenting research gaps, this review stimulates researchers to establish practically applicable sustainability performance evaluation frameworks to help assess and compare the degree of sustainability, leading to more sustainable business practices. The review is unique in defining corporate sustainability performance evaluation for the first time, exploring the gap between sustainability accounting and sustainability assessment, and coming up with a structured overview of innovative research recommendations about integrating analytical assessment methods into conceptual sustainability frameworks.

    2018-06-01

    Full Text Available Sustainability in project operations such as financial, social and environmental sustainability is one of the most prominent issues of the present times to address. The increased focus on sus-tainable business operations has changed the viewpoint of researchers and corporate community towards the project management. Today sustainability in business operations along with sustain-ability of natural and environmental resources are of paramount significance which has further caused a huge impact on conception, planning, scheduling and execution of the project manage-ment activities. In this paper, a literature review between 1987 and 2018 on different issues af-fecting the sustainability in project management is carried out. The present study also identifies and discusses the future possibilities to apply computational procedures in order to estimate and optimize the sustainability issues in the management of projects, for example the computational evolutionary algorithms can be applied to formulate the multi-objective decision-making problem after considering critical factors of sustainability in the projects and then yielding optimized solu-tions for the formulated problem to achieve sustainability in the projects. A new integrated framework with the inclusion of feedback function for assessment of each decision and actions taken towards the sustainability of the projects is also identified and presented.

    As the 20th century draws to a close, both individual countries and the world community face challenging problems related to the supply and use energy. These include local and regional environmental impacts, the prospect of global climate and sea level change associated with the greenhouse effect, and threats to international relations in connection with oil supply or nuclear proliferation. For developing countries, the financial cost of providing energy to provide basic needs and fuel economic development pose an additional burden. To assess the magnitude of future problems and the potential effectiveness of response strategies, it is important to understand how and why energy use has changed in the post and where it is heading. This requires study of the activities for which energy is used, and of how people and technology interact to provide the energy services that are desired. The authors and their colleagues have analyzed trends in energy use by sector for most of the world`s major energy-consuming countries. The approach we use considers three key elements in each sector: the level of activity, structural change, and energy intensity, which expresses the amount of energy used for various activities. At a disaggregated level, energy intensity is indicative of energy efficiency. But other factors besides technical efficiency also shape intensity.

    The coal industry in the United States has become a world leader in safety, productivity, and environmental protection in the mining of coal. The {open_quotes}pick-and-shovel{close_quotes} miner with mangled limbs and black lung disease has been replaced by the highly skilled technicians that lead the world in tons per man-hour. The gob piles, polluted streams, and scared land are a thing of the past. The complementary efforts of the DOE and EPRI-funded programs in coal utilization R&D and the Clean Coal Technology Program commercial demonstrations, have positioned the power generation industry to utilize coal in a way that doesn`t pollute the air or water, keeps electrical power costs low, and avoids the mountains of waste material. This paper reviews the potential for advanced coal utilization technologies in new power generation applications as well as the repowering of existing plants to increase their output, raise their efficiency, and reduce pollution. It demonstrates the potential for these advanced coal-fueled plants to play a complementary role in future planning with the natural gas and oil fired units currently favored in the market place. The status of the US program to demonstrate these technologies at commercial scale is reviewed in some detail.

    2010-01-01

    Most of the studies on the Indian energy sector focus on the possible future scenarios of Indian energy system development without considering the management dimension to the problem-how to ensure a smooth transition to reach the desired future state. The purpose of this paper is to highlight some sector management concerns to a sustainable energy future in the country. The paper follows a deductive approach and reviews the present status and possible future energy outlooks from the existing literature. This is followed by a strategy outline to achieve long-term energy sustainability. Management challenges on the way to such a sustainable future are finally presented. The paper finds that the aspiration of becoming an economic powerhouse and the need to eradicate poverty will necessarily mean an increase in energy consumption unless a decoupling of energy and GDP growth is achieved. Consequently, the energy future of the country is eminently unsustainable. A strategy focussing on demand reduction, enhanced access, use of local resources and better management practices is proposed here. However, a sustainable path faces a number of challenges from the management and policy perspectives.

    In a first chapter, this report proposes an overview of the world climate negotiation process within the COPs: structuring of the climate regime in Rio, a very slow process, a victory of market for quota over tax, the emergence of new climate geopolitics, and difficult climate governance. The second part outlines that the transition towards a de-carbonated world is not negotiable any longer because of the reality of climate change and of its consequences, and of a necessary alternative approach in front of an acknowledged failure. The third part highlights the different ways of a transition towards a more sustainable model by negotiation: evolution towards a new governance, a necessary transformation of the energy system, the assignment of a carbon price, to put the support to fossil energies into question again, to implement innovating financing means as a keystone of an ambitious agreement, to define more sustainable and more carbon saving policies (in urban planning, in production, in agriculture), to preserve and restore carbon sinks, and to territorialize climate again. The second part reports several hearings, and the content of the discussion within the Commission

  11. MHR fuel cycle options for future sustainability of nuclear power

    Baxter, Alan; Venneri, Francesco; Rodriguez, Carmelo; Fikani, Michael

    2005-01-01

    The future sustainability of the nuclear option is not significantly tied to the level of resources. For example, current high quality uranium reserves (∼3.34x10 6 tons) are enough for more than 55 years at present consumption rates (IAEA estimate). Doubling of the present uranium ore price (∼$26/kg) could create about a tenfold increase in resources, providing more than 550 years of supply at present rates (World Nuclear Association estimate). There are also thorium reserves which are estimated to be about three times those of uranium, and would allow for a significant increase in annual consumption levels. The key to a sustainable nuclear future is really tied to the political and technical problems of long term waste disposal, and the perceived risks of nuclear weapons proliferation. Thus fuel cycle options for a sustainable nuclear future must address and solve these issues. High temperature, Gas-Cooled, Graphite Moderated, reactors (MHRs) have nuclear and operational characteristics to provide multiple fuel cycle options to solve these issues. Three fuel cycles for the MHD are described in this paper, and their capabilities for meeting a sustainable nuclear future in terms of nuclear waste minimization and destruction, and reduction of proliferation risk, are discussed.

    2013-01-01

    Full Text Available Throughout the history people were fascinated and curious about the future. The future was, and still is seen as a key for prosperous development in all aspects of the society. As such, new discipline is developed – future studies.This paper discusses the discipline of future studies and its role in the society and science. Future studies are analyzed in the context of sustainable development. It is argued that future studies and sustainable development are complementary in nature. Based on analysis of most developed countries in the world, that spend the greatest portion of their budget on research, development and science in comparison to the rest of the world, there is a conclusive link between investments in research, development and science, and the recognition of the importance of thinking about the future. Those countries started to formalize their future orientation in many respected research centres and universities through their educational programs and research. That situation poses the need for other, less well off countries, to follow up.

  14. Sustainability and Convergence: The Future of Corporate Governance Systems?

    Directory of Open Access Journals (Sweden)

    Daniela M. Salvioni

    2016-11-01

    Full Text Available In today’s world, a sustainable approach to corporate governance can be a source of competitive advantage and a long-term success factor for any firm. Sustainable governance requires that the board of directors considers economic, social and environmental expectations in an integrated way, no matter what ownership structure and formal rules of corporate governance apply to the company: this mitigates the traditional differences between insider and outsider systems of corporate governance. Previous studies failed to consider the contribution of sustainability in the process of corporate governance convergence. Therefore, the aim of this article is to fill the gap in the existing literature by means of a qualitative analysis, supporting the international debate about convergence of corporate governance systems. The article describes the evolution of outsider and insider systems in the light of the increasing importance of sustainability in the board’s decision-making and firm’s operation to satisfy the needs of all the company’s stakeholders. According to this, a qualitative content analysis developed with a directed approach completes the theoretical discussion, demonstrating that sustainability can bring de facto convergence between outsider and insider corporate governance systems. The article aims to be a theoretical starting point for future research, the findings of which could also have practical implications: the study encourages the policy makers to translate the sustainable business best practices into laws and recommendations, strengthening the mutual influence between formal and substantial convergence.

    Full Text Available Nowadays, people are living in a continuous changing world, which faces a lot of difficulties, such as increased poverty, human-induced climate change, different diseases, natural disasters, etc. The challenges that humans have to face are not new, but they are important because the future of our society is connected to the way we solve our present problems. In this context, it becomes more and more obvious that the dimension and the importance of educational processes are crucial for the evolution of our society itself. Moreover, educational processes are the ones to tell us about the past and to shape the future, helping society to obtain a sustainable development. Starting from this point of view, this paper aims to emphasize the way education and sustainable development is influencing each other in the globalization era.

  16. A sustainable future for humanity? How can psychology help?

    Oskamp, S

    2000-05-01

    The sustainability of human life on Earth in the future is in danger. Human actions are producing many harmful and possibly irreversible changes to the environmental conditions that support life on Earth. This article summarizes major threats to Earth's environment, including global warming, ozone layer destruction, exhaustion of fisheries and agricultural land, and widespread exposure to toxic chemicals. Unless they are overcome, these changes will make human life increasingly miserable and eventually may make Earth nearly uninhabitable for future generations. These threats are caused by patterns of human behavior, particularly over-population and over-consumption. Urgent changes to human lifestyles and cultural practices are required for the world to escape ecological disaster, and psychologists should lead the way in helping people adopt sustainable patterns of living. Specific steps toward that goal are proposed in this and the following four articles.

  17. Sustainability of plant-based diets: back to the future.

    Science.gov (United States)

    Sabaté, Joan; Soret, Sam

    2014-07-01

    Plant-based diets in comparison to diets rich in animal products are more sustainable because they use many fewer natural resources and are less taxing on the environment. Given the global population explosion and increase in wealth, there is an increased demand for foods of animal origin. Environmental data are rapidly accumulating on the unsustainability of current worldwide food consumption practices that are high in meat and dairy products. Natural nonrenewable resources are becoming scarce, and environmental degradation is rapidly increasing. At the current trends of food consumption and environmental changes, food security and food sustainability are on a collision course. Changing course (to avoid the collision) will require extreme downward shifts in meat and dairy consumption by large segments of the world's population. Other approaches such as food waste reduction and precision agriculture and/or other technological advances have to be simultaneously pursued; however, they are insufficient to make the global food system sustainable. For millennia, meatless diets have been advocated on the basis of values, and large segments of the world population have thrived on plant-based diets. "Going back" to plant-based diets worldwide seems to be a reasonable alternative for a sustainable future. Policies in favor of the global adoption of plant-based diets will simultaneously optimize the food supply, health, environmental, and social justice outcomes for the world's population. Implementing such nutrition policy is perhaps one of the most rational and moral paths for a sustainable future of the human race and other living creatures of the biosphere that we share. © 2014 American Society for Nutrition.

    2000-01-01

    The VROM Council offered to host a workshop (27-28 October 2000) for a group of European environmental advisory bodies. This meeting is meant as a kick-off for a working group on energy and climate change. The workshop may help to develop standpoints of the advisory bodies on the basis of shared knowledge of problem perceptions and proposed solutions in other EU countries. This may increase the common denominator and thus promote common EU policies. The proposed title for this workshop is: Reconciling a sustainable energy future with the liberalisation and privatisation of the European energy market One of the participating councils from each country is expected to draft a report on the policies directed at a sustainable energy future in their respective countries. These reports should include the following elements of the national policies and relevant proposals of the councils: a brief description of the current energy supply and a lookout on sustainable development in the energy sector; .a description of the liberalisation and privatisation of the energy market, including the institutional reform (government involvement), juridical changes and realisation path and, if applicable, how the share of non fossil energy generation is enlarged; a description of how in the future a sustainable energy supply will be promoted, including (options for) policy strategies, measures and instruments; and a description of the European Union (EU) policy that is conditional for the realisation of these national policies. The VROM Council has asked CE to produce the report for the Netherlands. The report is organised as follows. Chapter 2 gives a brief description of the current Dutch energy and CO2 characteristics. Chapter 3 gives an overview of Dutch energy policy and chapter 4 an overview of Dutch climate policy. The chapters 5-7 give the views of the various councils on energy and climate policy (AER, VROMRaad, and SER). The final chapter, chapter 8, gives some suggestions for

    International Nuclear Information System (INIS)

    Echavarri, L.

    2002-01-01

    Full text: Nuclear energy is an established component of electricity supply worldwide (16%) and in particular in OECD (nearly a quarter). It is supported by a mature industry benefiting from extensive experience (more than 8 000 reactor years of commercial operation) and dynamic R and D programmes implemented by governments and industries. Existing nuclear power plants are competing successfully in deregulated electricity markets owing to their low marginal production costs, their technical reliability (availability factors exceeding 80% in many countries) and good safety performance. Stringent safety requirements and radiation protection regulations in place in OECD countries allow potential impacts of nuclear energy facilities on human health and the environment to remain extremely low. Furthermore, nuclear energy, a nearly carbon free source, contributes to alleviating the risk of global climate change (worldwide, GHG emissions from the energy sector are already 8% lower than they would be without nuclear energy). Issues related to high-level waste management and disposal are being addressed in comprehensive, step by step approach. Progress towards the implementation of deep geological repositories is being demonstrated (e.g., Yucca Mountain in the US, Olkiluoto in Finland) and research on innovative fuel cycles aiming at partitioning and transmutation of minor actinides is being actively pursued. Up to 2010-2020, nuclear energy will maintain its role mainly through capacity upgrade and lifetime extension of existing plants, in many cases the most cost effective means to increase power capacity and generation. Examples are provided by utility policies and decisions in a number of OECD countries (e.g., Spain, Sweden, Switzerland, UK, US). Although only few new units are being or will be built in the very near term, their construction and operation is bringing additional experience on advanced evolutionary nuclear systems and paving the way for the renaissance of

  20. Towards a sustainably certifiable futures contract for biofuels

    International Nuclear Information System (INIS)

    Mathews, John A.

    2008-01-01

    How are biofuels to be certified as produced in a sustainable and responsible fashion? In the global debate over this issue, one party to the proceedings seems rarely to be mentioned - namely the commodities exchanges through which a global biofuels market is being created. In this contribution, I propose a solution to the problem of sustainability certification through a biofuels futures contract equipped with 'proof of origin' documentation. The proposal does not call for any radical break with current practice, extending existing certification procedures with a requirement for the vendor to provide documentation, probably in barcoded form, of the history of the biofuel offered for sale, including plantation and biorefinery where the biofuel was produced and subsequent blendings it may have undergone. The proposal is thus compatible with the blending practices of large global traders, whose activities are the source of the difficulties of other approaches to certification. It is argued that if such a sustainable futures contract for bioethanol (in the first instance) were to be introduced, then it would likely trade at a premium and become the primary vehicle for North-South trade in biofuels.

    2013-01-01

    Full Text Available Abstract Physiological anthropology presently covers a very broad range of human knowledge and engineering technologies. This study reviews scientific inconsistencies within a variety of areas: sitting posture; negative air ions; oxygen inhalation; alpha brain waves induced by music and ultrasound; 1/f fluctuations; the evaluation of feelings using surface electroencephalography; Kansei; universal design; and anti-stress issues. We found that the inconsistencies within these areas indicate the importance of integrative thinking and the need to maintain the perspective on the biological benefit to humanity. Analytical science divides human physiological functions into discrete details, although individuals comprise a unified collection of whole-body functions. Such disparate considerations contribute to the misunderstanding of physiological functions and the misevaluation of positive and negative values for humankind. Research related to human health will, in future, depend on the concept of maintaining physiological functions based on consistent science and on sustaining human health to maintain biological welfare in future generations.

    NASA scientists and many others are contributing to the growing knowledge of our Earth and its ecosystems. Satellites measure sea level rise, and changes in vegetation and air pollutants that travel between countries and continents. The U.S. federal government seeks to be a leader in environmental sustainability efforts through various Executive Orders and policies that save energy, reduce waste, and encourage less reliance on oil as an energy source. NASA, as an agency that is by nature focused on the future, has much to contribute to these efforts. The NASA mission is 'To understand and protect our home planet, to explore the universe and search for life, to inspire the next generation of explorers as only NASA can.' Pollution prevention, affirmative procurement and sustainable design are all programs that are under way at NASA. But more can be done. By sharing ideas and learning from other organizations as well as from the talented workforce we are a part of, JSC can improve its sustainability performance and spread the benefits to our community.

    2008-01-01

    A major challenge - some would argue, the major challenge facing our planet today - relates to the problem of anthropogenic-driven climate change and its inextricable link to our global society's present and future energy needs [King, D.A., 2004. Environment - climate change science: adapt, mitigate, or ignore? Science 303, 176-177]. Hydrogen and fuel cells are now widely regarded as one of the key energy solutions for the 21st century. These technologies will contribute significantly to a reduction in environmental impact, enhanced energy security (and diversity) and creation of new energy industries. Hydrogen and fuel cells can be utilised in transportation, distributed heat and power generation, and energy storage systems. However, the transition from a carbon-based (fossil fuel) energy system to a hydrogen-based economy involves significant scientific, technological and socioeconomic barriers to the implementation of hydrogen and fuel cells as clean energy technologies of the future. This paper aims to capture, in brief, the current status, key scientific and technical challenges and projection of hydrogen and fuel cells within a sustainable energy vision of the future. We offer no comments here on energy policy and strategy. Rather, we identify challenges facing hydrogen and fuel cell technologies that must be overcome before these technologies can make a significant contribution to cleaner and more efficient energy production processes.

    1997-01-01

    Long known for its vast scale and fierce resistance to change, the US power industry is poised for a sweeping transformation. Although driven by many of the same forces propelling the telecommunications revolution, the electricity industry has received only a fraction as much attention. Yet the electric industry is far larger, with a current investment per customer of $6,000--double that of the phone and cable industries combined. Moreover, unlike telecommunications, the future of the power industry will have an enormous impact on the global environment. The glimmerings of a more efficient, decentralized, and less-polluting power system are beginning to capture the interest--and even the investment dollars--of some. In this paper, the authors describe the route to a more environmentally sustainable electric industry to power the twenty-first century

    2009-10-01

    Full Text Available Transportation is facing fundamental change due to the rapid depletion of fossil fuels, environmental and health problems, the growing world population, rising standards of living with more individual mobility and the globalization of trade with its increasing international transport volume. To cope with these serious problems benign, renewable energy systems and much more efficient drives must be multiplied as rapidly as possible to replace the polluting combustion engines with their much too low efficiency and high fuel logistics cost. Consequently the vehicles of the future must be non-polluting and super-efficient, i.e. electric. The energy supply must come via smart grids from clean energy sources not affecting the health, climate and biosphere. It is shown how this transition to the clean, sustainable energy age is possible, feasible and why it is urgent. The important role of international ISO, IEC and ITU standards and the need for better legislation by means of the Global Energy Charter for Sustainable Development are also highlighted.

    Technological advances have resulted development of a lot of electronic products for continuously increasing number of customers. As the customer taste and features of these products change rapidly, the life cycles have come down tremendously. Therefore, a large volume of e-wastes are now emanated every year. This scenario is very much predominant in Malaysia. On one hand e-wastes are becoming environmental hazards and affecting the ecological imbalance. On the other, these wastes are remaining still economically valuable. In Malaysia, e-waste management system is still in its nascent state. This paper describes the current status of e-waste generation and recycling and explores issues for future e-waste management system in Malaysia from sustainable point of view. As to draw some factual comparisons, this paper reviews the e-waste management system in European Union, USA, Japan, as a benchmark. Then it focuses on understanding the Malaysian culture, consumer discarding behavior, flow of the materials in recycling, e-waste management system, and presents a comparative view with the Swiss e-waste system. Sustainable issues for e-waste management in Malaysia are also presented. The response adopted so far in collection and recovery activities are covered in later phases. Finally, it investigates the barriers and challenges of e-waste system in Malaysia.

  10. Key Assets for a Sustainable Low Carbon Energy Future

    Carre, Frank

    2011-10-01

    Since the beginning of the 21st century, concerns of energy security and climate change gave rise to energy policies focused on energy conservation and diversified low-carbon energy sources. Provided lessons of Fukushima accident are evidently accounted for, nuclear energy will probably be confirmed in most of today's nuclear countries as a low carbon energy source needed to limit imports of oil and gas and to meet fast growing energy needs. Future challenges of nuclear energy are then in three directions: i) enhancing safety performance so as to preclude any long term impact of severe accident outside the site of the plant, even in case of hypothetical external events, ii) full use of Uranium and minimization long lived radioactive waste burden for sustainability, and iii) extension to non-electricity energy products for maximizing the share of low carbon energy source in transportation fuels, industrial process heat and district heating. Advanced LWRs (Gen-III) are today's best available technologies and can somewhat advance nuclear energy in these three directions. However, breakthroughs in sustainability call for fast neutron reactors and closed fuel cycles, and non-electric applications prompt a revival of interest in high temperature reactors for exceeding cogeneration performances achievable with LWRs. Both types of Gen-IV nuclear systems by nature call for technology breakthroughs to surpass LWRs capabilities. Current resumption in France of research on sodium cooled fast neutron reactors (SFRs) definitely aims at significant progress in safety and economic competitiveness compared to earlier reactors of this type in order to progress towards a new generation of commercially viable sodium cooled fast reactor. Along with advancing a new generation of sodium cooled fast reactor, research and development on alternative fast reactor types such as gas or lead-alloy cooled systems (GFR & LFR) is strategic to overcome technical difficulties and/or political

    One of the four main objectives of the U.S. Global Change Research Program's (USGCRP's) Strategic Plan is to "Conduct Sustained Assessments", which seeks to build a process that synthesizes and advances the state of scientific knowledge on global change, develops future scenarios and potential impacts, and evaluates how effectively science is being and can be used to inform and support the Nation's response to climate change. To do so, USGCRP strives to establish a standing capacity to conduct national climate assessments with sectoral and regional information to evaluate climate risks and opportunities, and to inform decision-making, especially with regard to resiliency planning and adaptation measures. Building on the success of the 3rd National Climate Assessment (NCA) (2014), we discuss the range of USGCRP activities that embody the sustained assessment concept. Special reports, such as the recent Climate and Human Health Assessment and upcoming Climate Science Special Report, fill gaps in our understanding and provide crucial building blocks for next NCA report (NCA4). To facilitate the use of consistent assumptions across NCA4, new scenario products for climate, population, and land use will be made available through initiatives such as NOAA's Climate Resilience Toolkit. NCA4 will be informed by user engagement to advance the customization of knowledge. The report will strive to advance our ability to quantify various risks, monetize certain impacts, and communicate the benefits (i.e., avoided impacts) of various mitigation pathways. NCAnet (a national network of climate-interested stakeholders) continues to grow and foster collaborations across levels of governance and within civil society. Finally, USGCRP continues to actively engage with other assessment processes, at international, state, city, and tribal levels, to exchange ideas and to facilitate the potential for "linked" assessments across spatial scales.

    Uprising energy crisis is predicted to be critically challenging in the foreseeable future where existing fossil fuel reservoirs are fast depleting and their extensive usage is posing serious health-related concerns to biological life on earth. To cover up these exhaustible energy resources, extensive efforts are going on to discover new frontiers in generating alternative energy sources on sustainable, renewable, and most importantly environment-friendly basis. In this context, biofuels (biomasses derived fuels) are seemed to be a promising solution considering the economical and applicable aspects. The generation of biofuels in another challenging task where the selection of raw materials for biofuel synthesis is of prime importance. Lignocellulosic biomass (residual plant-derived wastes) represent the largest resource substrate available on earth and could be used as a feedstock to generate biofuels such as bioethanol, biodiesel, biogas etc. in an eco-efficient, low cost, easily manageable and significantly in an ecosphere protected way. The current review summarizes the cutting-edge research on lignocellulosic biomass conversion to the renewable biofuel end products with concisely describing the lignocellulosic structural dimensions, sources, pretreatments, processing methodologies and ultimate challenges at the lower end.

    1997-02-01

    The National Educator`s Workshop (NEW): Update 96 was held October 27--30, 1996, and was hosted by Los Alamos National Laboratory. This was the 11th annual conference aimed at improving the teaching of material science, engineering and technology by updating educators and providing laboratory experiments on emerging technology for teaching fundamental and newly evolving materials concepts. The Hydrogen Education Outreach Activity at Los Alamos National Laboratory organized a special conference theme: Hydrogen and the Materials of a Sustainable Energy Future. The hydrogen component of the NEW:Update 96 offered the opportunity for educators to have direct communication with scientists in laboratory settings, develop mentor relationship with laboratory staff, and bring leading edge materials/technologies into the classroom to upgrade educational curricula. Lack of public education and understanding about hydrogen is a major barrier for initial implementation of hydrogen energy technologies and is an important prerequisite for acceptance of hydrogen outside the scientific/technical research communities. The following materials contain the papers and view graphs from the conference presentations. In addition, supplemental reference articles are also included: a general overview of hydrogen and an article on handling hydrogen safely. A resource list containing a curriculum outline, bibliography, Internet resources, and a list of periodicals often publishing relevant research articles can be found in the last section.

  17. Sustaining the future: the role of nuclear power in meeting future world energy needs

    International Nuclear Information System (INIS)

    Duffey, R.; Sun, Y.

    2003-01-01

    A description is given of recently informed analyses showing the potential that nuclear power has in meeting global energy demands. For both the electricity and transportation sectors, we can quantify the beneficial effects on the environment, and we show how nuclear power deserves credit for its role in assisting future world energy, environmental and economic sustainability. The continuing expansion of the world's and Asia's energy needs, coupled with the need to reduce greenhouse gas (GHG) and other emissions, will require new approaches for large scale energy production and use. This is particularly important for China and Asia with respect to meeting both the energy demand and sustainability challenges. We show and explore the role of nuclear power for large-scale energy applications, including electricity production and hydrogen for transportation. Advanced nuclear technologies, such as those like CANDU's next generation ACR, can meet future global energy market needs, avoid emissions, and mitigate the potential for global climate change. We use the latest IPCC Scenarios out to the year 2100 as a base case, but correct them to examine the sensitivity to large scale nuclear and hydrogen fuel penetration. We show a significant impact of nuclear energy on energy market penetration, and in reducing GHGs and other emissions in the coming century, particularly in the industrial developing world and in Asia. This is achieved without needing emissions credits, as are used or needed as economic support for other sources, or for subsidies via emissions trading schemes. Nuclear power offers the relatively emissions-free means, both to provide electricity for traditional applications and, by electrolytic production of hydrogen, to extend its use deep into the transportation sector. For the published IPCC Marker Scenarios for Asia we show the reduction in GHG emissions when electrolysis using electricity from nuclear power assists the introduction of hydrogen as a fuel

    Nature's photosynthesis uses the sun's energy with chlorophyll in plants as a catalyst to recycle carbon dioxide and water into new plant life. Only given sufficient geological time, millions of years, can new fossil fuels be formed naturally. The burning of our diminishing fossil fuel reserves is accompanied by large anthropogenic CO(2) release, which is outpacing nature's CO(2) recycling capability, causing significant environmental harm. To supplement the natural carbon cycle, we have proposed and developed a feasible anthropogenic chemical recycling of carbon dioxide. Carbon dioxide is captured by absorption technologies from any natural or industrial source, from human activities, or even from the air itself. It can then be converted by feasible chemical transformations into fuels such as methanol, dimethyl ether, and varied products including synthetic hydrocarbons and even proteins for animal feed, thus supplementing our food chain. This concept of broad scope and framework is the basis of what we call the Methanol Economy. The needed renewable starting materials, water and CO(2), are available anywhere on Earth. The required energy for the synthetic carbon cycle can come from any alternative energy source such as solar, wind, geothermal, and even hopefully safe nuclear energy. The anthropogenic carbon dioxide cycle offers a way of assuring a sustainable future for humankind when fossil fuels become scarce. While biosources can play a limited role in supplementing future energy needs, they increasingly interfere with the essentials of the food chain. We have previously reviewed aspects of the chemical recycling of carbon dioxide to methanol and dimethyl ether. In the present Perspective, we extend the discussion of the innovative and feasible anthropogenic carbon cycle, which can be the basis of progressively liberating humankind from its dependence on diminishing fossil fuel reserves while also controlling harmful CO(2) emissions to the atmosphere. We also

  3. Breaking Resilience for a Sustainable Future: Thoughts for the Anthropocene

    Directory of Open Access Journals (Sweden)

    Marion Glaser

    2018-02-01

    Full Text Available Strong resilience of a system usually enables the protection of a status quo. Most resilience studies assume that resilience-building is the central objective of sustainability work. Even though transformation has become a central theme in development and social-ecological debates, questions surrounding the weakening resilience of undesired system states are rarely analyzed. We suggest that resilience studies not only serve to protect systems and feedbacks we want to maintain, but may also help to understand and overcome chronic, undesirable,—and thus wicked—resilience. This contribution focuses on reef fisheries in the Spermonde Island Archipelago in Indonesia, based on social and ecological studies between 2004 and 2016. We identify a number of interlocking wickedly resilient vicious cycles as predominant drivers of the impoverishment of fishing households and the overexploited, polluted and degraded state of the coral reefs that fishers' livelihoods depend on. We argue that, more often than not in the Anthropocene, breaking resilience has a central role in the pursuit of sustainable human-nature relations. Therefore, the link between the resilience and the transformation debates needs to be much more explicitly made. Breaking interlocking, wicked resilience at multiple levels is needed to move toward sustainable human-nature relations from the local to the global level. There are lacunae in debate, literature, and research practice as to when, where and how wicked resilience might need to be weakened. A more complete resilience lens is particularly needed under Anthropocene conditions to support the unmaking of chronically resilient, anthropogenic systems.

    The research described here is the first study on the use of sustainable, plant-based biopolymers in conservation practice. Two applications of biopolymers to conservation were investigated – in commercial bioplastics as substitutes for petroleum-based plastic packaging, and in novel adhesive...... polylactic acid (PLA) bags and containers became brittle and opaque at a relative humidity (RH) above 65%. FTIR spectroscopy and thermogravimetric analysis suggested that PLA hydrolysed to produce acids. PLA/cornstarch bags fragmented on ageing and formed a gel at high RH levels. A 5 wt% solution of adhesive...

    The ability to design technological solutions that address sustainability is considered pivotal to the future of the planet and its people. As technology professionals engineers are expected to play an important role in sustaining society. The present article aims at exploring sustainability concepts of newly enrolled engineering students in Denmark. Their understandings of sustainability and the role they ascribe to sustainability in their future professional practice is investigated by means of a critical discourse analysis including metaphor analysis and semiotic analysis. The sustainability construal is considered to delimit possible ways of dealing with the concept in practice along the engineering education pathway and in professional problem solving. Five different metaphors used by the engineering students to illustrate sustainability are identified, and their different connotative and interpretive implications are discussed. It is found that sustainability represents a dilemma to the engineering students that situates them in a tension between their technology fascination and the blame they find that technological progress bears. Their sustainability descriptions are collected as part of a survey containing among other questions one open-ended, qualitative question on sustainability. The survey covers an entire year group of Danish engineering students in the first month of their degree study.

    Eigen, J

    1995-11-01

    Cities are the most important sites of socioeconomic development, offering significant economies of scale in providing jobs, housing and services, and are important centers of productivity and social advancement. Cities also absorb two thirds of developing countries' population growth; the developing world's cities will absorb more than 75% of total world population increase during 1990-2000. Urban environmental problems, however, seriously threaten the full realization of cities' potential socioeconomic contributions. Environmental degradation has many costs, leads to significant inefficiencies in the use of local resources, compounds inequities, and threatens the sustainability of development achievements. Urban development and environmental management therefore cannot be considered separately. Actions in the city affect the environment, and the environment in turn affects the city. Agenda 21, a global agenda for cooperation which emerged from the 1992 UN Conference on Environment and Development emphasizing cross-sectoral coordination, the decentralization of decision making, and broad-based participatory approaches to development management, and the Sustainable Cities Program are discussed.

    2002-01-01

    This article traces the history of Sweden's energy policy from its reliance on fossil fuel imports in 1970 to the shift towards sustainable energy systems. The levying of a general energy tax and carbon dioxide taxation, and Sweden's large reduction in emissions are reported. Energy conservation, energy efficiency standards, the revision of building codes for energy efficiency, and innovative energy efficiency programmes are discussed. Renewable energy technologies are examined covering hydropower and wind power plants in Sweden, the use of biofuels, the development of new heat pumps, and solar heaters. The suggested long-term goal of 50% reduction in carbon dioxide emissions from 1990 to 2050 is considered. Swedish taxes on fuel for heat generation (1999) are listed

    Recent reforms of the European Union’s Common Agricultural Policy (CAP) have set in motion a process of increased market orientation in the agricultural sector, a process that will be intensified by trade liberalization if an agreement is reached under the World Trade Organization (WTO......). It is widely expected that both CAP reforms and a WTO agreement will also lead to a more environmentally friendly European agriculture. It is conceivable, however, that market demand would instead provide renewed incentives for intensive agricultural production. Opening European agriculture to more competition...... in the world market could increase pressure to slacken regulatory requirements on agriculture. Thus, the question of whether liberalization will hinder or promote environmentally sustainable production methods in agriculture is unresolved. This paper analyses different scenarios of agricultural policy...

    Full Text Available The USACOR Report forecasts that by 2050 the Arctic will become the major supplier of energy to the world, in particular oil and natural gas, and natural resources such as mineral water. In the coming decades, the population in the Arctic region is projected to increase significantly due to the expansion of exploration for resources. The Report recommends that a Zero emission policy be implemented throughout the Arctic area for water emissions into the seas, rivers, or estuaries and oceans. The Report recommends that the Arctic Council guarantees safe navigation and environmental protection, establishing a Fund to cover expenses to purchase icebreakers and towards the cost of the personnel in order to assist commercial navigation in the Arctic region. The Arctic Council shall also issue environmental rules to regulate the mineral exploitation in the region and ensure that the wildlife is protected and that the exploitation of resources is conducted in a sustainable manner.

    Strong resilience of a system usually enables the protection of a status quo. Most resilience studies assume that resilience-building is the central objective of sustainability work. Even though transformation has become a central theme in development and social-ecological debates, questions...... surrounding the weakening resilience of undesired system states are rarely analyzed. We suggest that resilience studies not only serve to protect systems and feedbacks we want to maintain, but may also help to understand and overcome chronic, undesirable,—and thus wicked—resilience. This contribution focuses...... on reef fisheries in the Spermonde Island Archipelago in Indonesia, based on social and ecological studies between 2004 and 2016. We identify a number of interlocking wickedly resilient vicious cycles as predominant drivers of the impoverishment of fishing households and the overexploited, polluted...

    Kumar, K.; Bhagat, S.K.; Thakur, T.

    1998-01-01

    Although India has a fairly large interconnected power system among the developing countries, it accounts for tremendously high losses occurring in the system, and hence resulting in an inefficient operation. With the ever increasing cost of inflation and several other financial constraints, it is of paramount importance to maximise/optimise the continuity and quality of electric power supply at minimum investment. Also, this calls upon planning for optimum generating capacity and maintaining adequate spinning reserves. This article discusses the Indian scenario and deals with some strategic issues keeping in mind the problems concerning the future growth of the power industry. (author)

    2016-12-01

    Coasts are at the nexus of the Anthropocene, where land, marginal seas and atmosphere meet along a thin strip that is inhabited by nearly half the human population (Wolanski and Elliott, 2015). Coasts are often fringed by rich habitats such as mangroves, salt-marshes, inter-tidal mud and sand flats, seagrass meadows, kelp forests and coral reefs that provide a valuable range of ecosystem services to humans and to the adjacent marginal seas (Van den Belt and Costanza, 2011). It is the highly dynamic system that is constantly being reshaped by changing natural forces and anthropogenic activities. Coastal systems and human societies form coastal social-ecological systems that increasingly face multiple pressures, which threaten their ecological and economical sustainability. Common pressures include changes to land use and hydrology, land reclamation, coastal sand mining, harbour dredging, pollution and eutrophication, overexploitation such as overfishing, all in the context of climate change. During the 20th Century, coastal scientists studied the problems and issues arising along the coasts (Ramesh et al., 2015). Now, in the 21st Century, their focus must increasingly be about how to solve these problems and issues through better management and innovative approaches. To study these matters, two workshops were held in Yantai, P.R. China, in September 2015, hosted by the Yantai Institute of Coastal Zone Research, CAS. The outcome of these workshops is this special issue of Estuarine, Coastal and Shelf Science.

  18. A CONCEPTUAL FRAMEWORK FOR SUSTAINABLE URBANISATION IN FUTURE CHINA

    Directory of Open Access Journals (Sweden)

    Zbigniew Bromberek

    2009-03-01

    Full Text Available Rapid urbanisation of China is a phenomenon putting huge pressure on the society, environment and services in the existing cities. The growth of large regional centres is usually seen as an unwelcome but unavoidable both source and result of the Chinese urbanisation. The paper disputes this ‘unavoidability’ claim. The reasons for the present day urbanization and concurrent ‘de-ruralisation’ processes in China are outlined. Opportunities arising from IT-age technologies as life style-generating agents are presented. They are matched with the corresponding characteristics of the rural setting. The paper examines a possibility of urbanisation based on the existing village networks. A brief presentation of various possible social and economic benefits, derived from the village urbanisation, follows. The offered solution could adequately address issues of accommodation and job provision without losing energy expenditure and sustainable use of scarce resources from its focus. Environmental benefits stemming from this different approach to problems of development are then discussed. The paper is concluded with an attempt to predict whether (if at all and to what extent the proposal of the urban village is a feasible alternative to the current trends in the most populous country in the world.

    1992-01-01

    The potential for improving energy efficiency is enormous, but exploitation of this resource has slowed in recent years. This is regrettable for several reasons. First, not incorporating higher efficiency now often means passing up opportunities that will be more expensive or even impossible to implement in the future. This is especially true for long-lived capital, such as new buildings. Second, reduced research and development into new efficiency options will make it more difficult to accelerate the pace of efficiency improvements in the future. Finally, the flow of more efficient technologies to the non-OECD countries will be hindered by the slowdown in efficiency improvement in the OECD countries. Well-designed policies can help recapture the momentum that has been lost. Some key steps for stimulating more careful use of energy are: rationalize energy pricing and gradually internalize environmental externalities; improve present energy-using capital; implement energy-efficiency standards or agreements for new products and buildings; encourage higher energy efficiency in new products and buildings; promote international cooperation for R ampersand D technology transfer; adjust policies that encourage energy-intensive activities; and promote population restraint worldwide. 25 refs

    Energy-water-environment nexus is very important to attain COP21 goal, maintaining environment temperature increase below 2°C, but unfortunately two third share of CO2 emission has already been used and the remaining will be exhausted by 2050. A number of technological developments in power and desalination sectors improved their efficiencies to save energy and carbon emission but still they are operating at 35% and 10% of their thermodynamic limits. Research in desalination processes contributing to fuel World population for their improved living standard and to reduce specific energy consumption and to protect environment. Recently developed highly efficient nature-inspired membranes (aquaporin & graphene) and trend in thermally driven cycle\\'s hybridization could potentially lower then energy requirement for water purification. This paper presents a state of art review on energy, water and environment interconnection and future energy efficient desalination possibilities to save energy and protect environment.

  1. Finding synergy between local competitiveness and global sustainability to provide a future to nuclear energy

    International Nuclear Information System (INIS)

    Van Den Durpel, Luc; Yacout, Abdellatif; Wade, Dave

    2008-01-01

    The world's future energy needs will require a mix of energy conversion technologies matched to the local energy market needs while also responding to both local and global socio-political concerns, e.g. energy security, environmental impact, safety and non-proliferation. There is growing recognition worldwide that nuclear energy should not only be part of the solution but maybe as well play a larger share in future's energy supply. The sustainability of future nuclear energy systems is hereby important and a variety of studies have already shown that sustainability of nuclear energy from a resource perspective is achievable via the nuclear fuel cycle though where economic sustainability is essentially defined by the nuclear power plants. The main challenge in deploying sustainable nuclear energy systems will be to find synergies between this local competitiveness of nuclear power plants and the global resource sustainability defined via the nuclear fuel cycle. Both may go hand-in-hand in the long-term but may need government guidance in starting the transition towards such future sustainable nuclear energy systems. (authors)

    Filipkowski, A.

    2011-12-01

    The problem of Earth environmental destruction by human activities is becoming dangerous. Engineers responsible for the production of any goods should be well aware of the negative influence of their activities on the state of the planet. This is why the understanding of ecological problems is essential for people responsible for production and industrial design. The energy, which they consume, is increasing the greenhouse effect and the waste poisons the environment. So far, most courses on ecology are offered to specialists in environmental engineering. These courses are filled with many details. The Warsaw Academy of Computer Science, Management and Administration teaches students in the direction of management and production engineering. Upon completion, the students receive the degree of 'engineer'. Their future work will mainly concern management of different types of industrial enterprises and they will be responsible for organising it in such a way as to avoid a dangerous contribution to environmental pollution and climate change. This is why it was decided to introduce a new course entitled 'Principles of Ecology and Environmental Management'. This course is quite broad, concerning almost all technical, law and organisational aspects of the problem. The presentation is made in a spectacular way, aiming to convince students that their future activity must be environmentally friendly. It contains information about international activities in ecology, legal aspects concerning pollution, technical and information methods of monitoring and, finally, the description of 'green' solutions. Altogether, 27 hours of lectures and 15 hours of discussions and students' presentations complete the course. Details of this course are described in this paper.

    2018-02-01

    Based on previous studies and reflections collected from participants in a workshop at the 8th Nordic Health Promotion Research Network conference, we reveal current tendencies and discuss future challenges for health-promotion research regarding integration of sustainable development principles. Despite obvious interfaces and interactions between the two, our contention is that strategies for health promotion are not sufficiently integrated with strategies for sustainable development and that policies aimed at solving health or sustainability problems may therefore cause new, undesired and unforeseen environmental and health problems. As illustrated in previous research and as deliberated in the above-mentioned workshop, a number of barriers are identified. These are believed to be related to historical segregation, the conceptual understandings of health promotion and sustainable development, as well as the politics and implementation of policy goals in both areas. Three focal points are proposed as important challenges to address in future research: (a) the duality of health promotion and sustainability and how it can be handled in order to enhance mutually supportive processes between them; (b) the social dimension of sustainability and how it can be strengthened in the development of strategies for health promotion and sustainable development; and (c) exploring and identifying policy approaches and strategies for integrating health promotion and sustainable development.

    A new method for preparing carbon-free, temperature-stable Transmission Electron Microscope (TEM) grids is presented. An 80% Au/20% Pd metal film is deposited onto a 'holey' microgrid carbon supported on standard mixed-mesh Au TEM grids. Subsequently, the carbon film is selectively removed using plasma cleaning. In this way, an all-metal TEM film is made containing the 'same' microgrid as the original carbon film. Although electron transparency of the foil is reduced significantly, the open areas for TEM inspection of material over these areas are maintained. The metal foil can be prepared with various thicknesses and ensures good electrical conductivity. The new Au/Pd grids are stable to at least 775 K under vacuum conditions.

  6. Hydrogen role in a carbon-free energy mix

    International Nuclear Information System (INIS)

    2014-02-01

    Among the energy storage technologies under development today, there is today an increasing interest towards the hydrogen-based ones. Hydrogen generation allows to store electricity, while its combustion can supply electrical, mechanical or heat energy. The French Atomic Energy Commission (CEA) started to work on hydrogen technologies at the end of the 1990's in order to reinforce its economical interest. The development of these technologies is one of the 34 French industrial programs presented in September 2013 by the French Minister of productive recovery. This paper aims at identifying the hydrogen stakes in a carbon-free energy mix and at highlighting the remaining technological challenges to be met before reaching an industrial development level

    Over the past five years, the Department of Energy's Office of Basic Energy Sciences has engaged thousands of scientists around the world to study the current status, limiting factors and specific fundamental scientific bottlenecks blocking the widespread implementation of alternate energy technologies. The reports from the foundational BESAC workshop, the ten 'Basic Research Needs' workshops and the panel on Grand Challenge science detail the necessary research steps (http://www.sc.doe.gov/bes/reports/list.html). This report responds to a charge from the Director of the Office of Science to the Basic Energy Sciences Advisory Committee to conduct a study with two primary goals: (1) to assimilate the scientific research directions that emerged from these workshop reports into a comprehensive set of science themes, and (2) to identify the new implementation strategies and tools required to accomplish the science. From these efforts it becomes clear that the magnitude of the challenge is so immense that existing approaches - even with improvements from advanced engineering and improved technology based on known concepts - will not be enough to secure our energy future. Instead, meeting the challenge will require fundamental understanding and scientific breakthroughs in new materials and chemical processes to make possible new energy technologies and performance levels far beyond what is now possible.

    Full Text Available With the introduction of hydraulic fracturing technology, the United States has become the largest natural gas producer in the world with a substantial portion of the production coming from shale plays. In this review, we examined current hydraulic fracturing literature including associated wastewater management on quantity and quality of groundwater. We conclude that proper documentation/reporting systems for wastewater discharge and spills need to be enforced at the federal, state, and industrial level. Furthermore, Underground Injection Control (UIC requirements under SDWA should be extended to hydraulic fracturing operations regardless if diesel fuel is used as a fracturing fluid or not. One of the biggest barriers that hinder the advancement of our knowledge on the hydraulic fracturing process is the lack of transparency of chemicals used in the practice. Federal laws mandating hydraulic companies to disclose fracturing fluid composition and concentration not only to federal and state regulatory agencies but also to health care professionals would encourage this practice. The full disclosure of fracturing chemicals will allow future research to fill knowledge gaps for a better understanding of the impacts of hydraulic fracturing on human health and the environment.

    The aim of the study was to scope education staff capacity to meet the future needs of the healthcare workforce in practice across South West (SW) England. As individual nations come to terms with the impact of the incurred global debt, the university sector also faces a period of financial stringency and review of current resources. Additionally, there is growing evidence world-wide, of an increasing crisis in the recruitment and retention of healthcare educators. Using a survey approach, an audit of six universities in South West England completed a bespoke self-administered questionnaire between April and June 2008, when prior to and since these dates, major reforms have taken place. Data were entered into a spreadsheet and analysed using descriptive statistics. Considerable variation across professional groups was observed, particularly in staff/student ratios. Data indicates an ageing workforce with less than 20% of staff in possession of a doctorate. The results mirror other work and concerns from abroad, particularly in Nursing in identifying areas at risk in the education workforce. The potential for incentives to encourage practitioners into a career in education will do much to entice the best from practice to plan for succession, and, drive quality for patient benefit.

    The authors offered some insight into the strategic issues facing the electricity industry in Canada while also highlighting the many accomplishments of the various member companies. The future orientations were discussed. Climate change is the issue that seems to garner the most attention from media, governments and the public. The electricity industry is the only industry that possesses a concrete plan of action to address the issue of climate change, in the form of the Emissions Performance Equivalent Standard (EPES). During 2002, a Memorandum of Understanding (MOU) was signed between the Canadian Electricity Association and the Department of Fisheries and Oceans, the first of its kind. A compliance framework is now being developed. Some of the issues being worked on this year are a post-Kyoto ratification strategy, an energy efficiency initiative; a response to the Supreme Court ruling concerning pole attachments, a revised Environmental Commitment and Responsibility Program, the fifth Annual Washington Energy Forum, and an updated survey on Aboriginal relations. Several member companies provided their views, such as ATCO Electric and ATCO Power, British Columbia Hydro, Hydro One, Hydro-Quebec, Newfoundland and Labrador Hydro to name but a few. tabs., figs

    2015-01-01

    Resilience and sustainability will be two primary objectives of future cities. The violent consequences of extreme natural events and the environmental, social and economic burden of contemporary cities make the concepts of resilience and sustainability extremely relevant. In this paper we analyse the various definitions of resilience and sustainability applied to urban systems and propose a synthesis, based on similarities between the two concepts. According to the proposed approach, catastrophic events and the subsequent transformations occurring in urban systems represent a moment in the city life cycle to be seen in terms of the complex sustainability framework. Hence, resilience is seen as a requirement for urban system sustainability. In addition, resilience should be evaluated not only for single cities, with their physical and social systems, but also on a global scale, taking into account the complex and dynamic relationships connecting contemporary cities. © 2014 The Author(s).

    Managing freshwater resources sustainably under future climatic and hydrological uncertainty poses novel challenges. Rehabilitation of ageing infrastructure and construction of new dams are widely viewed as solutions to diminish climate risk, but attaining the broad goal of freshwater sustainability will require expansion of the prevailing water resources management paradigm beyond narrow economic criteria to include socially valued ecosystem functions and services. We introduce a new decision framework, eco-engineering decision scaling (EEDS), that explicitly and quantitatively explores trade-offs in stakeholder-defined engineering and ecological performance metrics across a range of possible management actions under unknown future hydrological and climate states. We illustrate its potential application through a hypothetical case study of the Iowa River, USA. EEDS holds promise as a powerful framework for operationalizing freshwater sustainability under future hydrological uncertainty by fostering collaboration across historically conflicting perspectives of water resource engineering and river conservation ecology to design and operate water infrastructure for social and environmental benefits.

EEDS holds promise as a powerful framework for operationalizing freshwater sustainability under future hydrological uncertainty by fostering collaboration across historically conflicting perspectives of water resource engineering and river conservation ecology to design and operate water infrastructure for social and environmental benefits.

    2017-12-01

    In 2015, the German Federal Ministry of Education and Research (BMBF) announced that the Science Year 2015 would focus on the "City of the Future". It called for innovative projects from cities and communities in Germany dedicated to exploring future options and scenarios for sustainable development. Among the successful respondents was the city of Lüneburg, located in the north of Germany, which was awarded funding to establish a community learning project to envision a sustainable future ("City of the Future Lüneburg 2030+"). What made Lüneburg's approach unique was that the city itself initiated the project and invited a broad range of stakeholders to participate in a community learning process for sustainable development. The authors of this article use the project as a blueprint for sustainable city development. Presenting a reflexive case study, they report on the process and outcomes of the project and investigate community learning processes amongst different stakeholders as an opportunity for transformative social learning. They discuss outputs and outcomes (intended as well as unintended) in relation to the specific starting points of the project to provide a context-sensitive yet rich narrative of the case and to overcome typical criticisms of case studies in the field.

    The InTeGrate Student Portal is a suite of web pages that utilize InTeGrate resources to support student success by providing undergraduates with tools and information necessary to be proactive in their career choices and development. Drawn from various InTeGrate workshops and programming, the Portal organizes these resources to illuminate a variety of career opportunities and pathways to both traditional and non-traditional jobs that support a sustainable future. Informed from a variety of sources including employers, practitioners, faculty, students, reports, and articles, the pages explore five facets: (1) sustainability across the disciplines, (2) workforce preparation, (3) professional communication, (4) teaching and teaching careers, and (5) the future of green research and technology. The first three facets explore how sustainability is integrated across disciplines and how sustainability and 'green' jobs are available in a wide range of traditional and non-traditional workplaces within and beyond science. They provide students guidance in preparing for this sustainability workforce, including where to learn about jobs and how to pursue them, advice for strengthening their job applications, and how to build a set of skills that employers seek. This advice encompasses classroom skills as well as those acquired and strengthened as part of extracurricular or workplace experiences. The fourth facet, aimed at teaching assistants with little or no experience as well as at students who are interested in pursuing teaching as a career, provides information and resources about teaching. The fifth facet explores future directions of technology and the need for innovations in the workforce of the future to address sustainability issues.

  7. Uranium (VI) solubility in carbonate-free ERDA-6 brine

    Energy Technology Data Exchange (ETDEWEB)

    Lucchini, Jean-francois [Los Alamos National Laboratory; Khaing, Hnin [Los Alamos National Laboratory; Reed, Donald T [Los Alamos National Laboratory

    2010-01-01

    When present, uranium is usually an element of importance in a nuclear waste repository. In the Waste Isolation Pilot Plant (WIPP), uranium is the most prevalent actinide component by mass, with about 647 metric tons to be placed in the repository. Therefore, the chemistry of uranium, and especially its solubility in the WIPP conditions, needs to be well determined. Long-term experiments were performed to measure the solubility of uranium (VI) in carbonate-free ERDA-6 brine, a simulated WIPP brine, at pC{sub H+} values between 8 and 12.5. These data, obtained from the over-saturation approach, were the first repository-relevant data for the VI actinide oxidation state. The solubility trends observed pointed towards low uranium solubility in WIPP brines and a lack of amphotericity. At the expected pC{sub H+} in the WIPP ({approx} 9.5), measured uranium solubility approached 10{sup -7} M. The objective of these experiments was to establish a baseline solubility to further investigate the effects of carbonate complexation on uranium solubility in WIPP brines.

    Aziz, Muhammad; Oda, Takuya; Kashiwagi, Takao

    2018-02-01

    Novel carbon-free integrated system of hydrogen production and storage from low rank coal is proposed and evaluated. To measure the optimum energy efficiency, two different systems employing different chemical looping technologies are modeled. The first integrated system consists of coal drying, gasification, syngas chemical looping, and hydrogenation. On the other hand, the second system combines coal drying, coal direct chemical looping, and hydrogenation. In addition, in order to cover the consumed electricity and recover the energy, combined cycle is adopted as addition module for power generation. The objective of the study is to find the best system having the highest performance in terms of total energy efficiency, including hydrogen production efficiency and power generation efficiency. To achieve a thorough energy/heat circulation throughout each module and the whole integrated system, enhanced process integration technology is employed. It basically incorporates two core basic technologies: exergy recovery and process integration. Several operating parameters including target moisture content in drying module, operating pressure in chemical looping module, are observed in terms of their influence to energy efficiency. From process modeling and calculation, two integrated systems can realize high total energy efficiency, higher than 60%. However, the system employing coal direct chemical looping represents higher energy efficiency, including hydrogen production and power generation, which is about 83%. In addition, optimum target moisture content in drying and operating pressure in chemical looping also have been defined.

    2000-01-01

    A new attempt has been demonstrated using carbon free Fe-Ni-Co martensitic alloys strengthened by Laves phase such as Fe 2 W or Fe 2 Mo to achieve homogeneous creep deformation at high temperatures under low stress levels. Creep behavior of the alloys is found to be completely different from that of the conventional high-Cr ferritic steels. The alloys exhibit gradual change in the creep rate with strain both in the transient and acceleration creep regions, and give a larger strain for the minimum creep rate. In these alloys the creep deformation takes place very homogeneously and no heterogeneous creep deformation is enhanced even at low stress levels. The minimum creep rates of the Fe-Ni-Co alloys at 700 C are found to be much lower than that of the conventional steel, which is due to fine dispersion strengthening useful even at 700 C in these alloys. It is thus concluded that the Fe-Ni-Co martensite strengthened by Laves phase is very useful to increase the creep resistance at elevated temperatures over 650 C. (orig.)

  10. Perspective on the French closed fuel cycle: Open towards energy future and sustainability

    International Nuclear Information System (INIS)

    2006-01-01

    Energy sustainability and nuclear energy nowadays are far reaching issues with many implications and as a consequence, any long term sustainable strategy needs to be flexible. In France, nuclear energy (427 TWh in 2004, 80% of national electricity production) is a major asset for clean electricity production and for meeting Kyoto protocol objective in France. The decision to build a future EPR reactor in France has been taken. Regarding back end and fuel cycle, the current reprocessing and recycling strategy, with the existing industrial system (Cogema La Hague and Melox), has proven to be reliable and efficient. It enables to meet sustainability requirements, now and in the long run: ensuring a good management of high level waste through vitrification, reducing the amount of nuclear spent fuel in interim storage, recycling valuable nuclear material (Pu), keeping the possibility to use Pu concentrated in MOX spent fuel to start FBR in the future. To maintain this possibility for the far future, EDF considers that the Generation IV program is of major importance in order to develop future fast reactors able to use plutonium and to ensure a full utilization of uranium resource, while optimizing high level waste management. EDF strategy is to keep the nuclear option open in the future, with a two-steps approach for the renewal of the current nuclear fleet: first, around 2020, with the launching of generation III reactors like EPR, and second, depending on the energy demand, launching of Generation IV systems, around 2040 or beyond. To meet this energy prospect, R and D efforts must be devoted to fast breeder reactors (sodium cooled, which benefits already from industrial experience, and gas cooled, under consideration for R and D). Globally, this strategy is open to future progress and optimisation as needed to meet long term energy sustainability. It appears the necessity of a good consistency between all the components of the nuclear system: reactors, fuel cycle

  11. Spatial Optimization of Future Urban Development with Regards to Climate Risk and Sustainability Objectives.

    Future development in cities needs to manage increasing populations, climate-related risks, and sustainable development objectives such as reducing greenhouse gas emissions. Planners therefore face a challenge of multidimensional, spatial optimization in order to balance potential tradeoffs and maximize synergies between risks and other objectives. To address this, a spatial optimization framework has been developed. This uses a spatially implemented genetic algorithm to generate a set of Pareto-optimal results that provide planners with the best set of trade-off spatial plans for six risk and sustainability objectives: (i) minimize heat risks, (ii) minimize flooding risks, (iii) minimize transport travel costs to minimize associated emissions, (iv) maximize brownfield development, (v) minimize urban sprawl, and (vi) prevent development of greenspace. The framework is applied to Greater London (U.K.) and shown to generate spatial development strategies that are optimal for specific objectives and differ significantly from the existing development strategies. In addition, the analysis reveals tradeoffs between different risks as well as between risk and sustainability objectives. While increases in heat or flood risk can be avoided, there are no strategies that do not increase at least one of these. Tradeoffs between risk and other sustainability objectives can be more severe, for example, minimizing heat risk is only possible if future development is allowed to sprawl significantly. The results highlight the importance of spatial structure in modulating risks and other sustainability objectives. However, not all planning objectives are suited to quantified optimization and so the results should form part of an evidence base to improve the delivery of risk and sustainability management in future urban development. © 2017 The Authors Risk Analysis published by Wiley Periodicals, Inc. on behalf of Society for Risk Analysis.

  12. Sustainability of UK shale gas in comparison with other electricity options: Current situation and future scenarios.

    Many countries are considering exploitation of shale gas but its overall sustainability is currently unclear. Previous studies focused mainly on environmental aspects of shale gas, largely in the US, with scant information on socio-economic aspects. To address this knowledge gap, this paper integrates for the first time environmental, economic and social aspects of shale gas to evaluate its overall sustainability. The focus is on the UK which is on the cusp of developing a shale gas industry. Shale gas is compared to other electricity options for the current situation and future scenarios up to the year 2030 to investigate whether it can contribute towards a more sustainable electricity mix in the UK. The results obtained through multi-criteria decision analysis suggest that, when equal importance is assumed for each of the three sustainability aspects shale gas ranks seventh out of nine electricity options, with wind and solar PV being the best and coal the worst options. However, it outranks biomass and hydropower. Changing the importance of the sustainability aspects widely, the ranking of shale gas ranges between fourth and eighth. For shale gas to become the most sustainable option of those assessed, large improvements would be needed, including a 329-fold reduction in environmental impacts and 16 times higher employment, along with simultaneous large changes (up to 10,000 times) in the importance assigned to each criterion. Similar changes would be needed if it were to be comparable to conventional or liquefied natural gas, biomass, nuclear or hydropower. The results also suggest that a future electricity mix (2030) would be more sustainable with a lower rather than a higher share of shale gas. These results serve to inform UK policy makers, industry and non-governmental organisations. They will also be of interest to other countries considering exploitation of shale gas.

    Sustaining food production, water quality, soil retention, flood, and climate regulation in agricultural landscapes is a pressing global challenge given accelerating environmental changes. Scenarios are stories about plausible futures, and scenarios can be integrated with biophysical simulation models to explore quantitatively how the future might unfold. However, few studies have incorporated a wide range of drivers (e.g., climate, land-use, management, population, human diet) in spatially explicit, process-based models to investigate spatial-temporal dynamics and relationships of a portfolio of ecosystem services. Here, we simulated nine ecosystem services (three provisioning and six regulating services) at 220 × 220 m from 2010 to 2070 under four contrasting scenarios in the 1,345-km 2 Yahara Watershed (Wisconsin, USA) using Agro-IBIS, a dynamic model of terrestrial ecosystem processes, biogeochemistry, water, and energy balance. We asked (1) How does ecosystem service supply vary among alternative future scenarios? (2) Where on the landscape is the provision of ecosystem services most susceptible to future social-ecological changes? (3) Among alternative future scenarios, are relationships (i.e., trade-offs, synergies) among food production, water, and biogeochemical services consistent over time? Our results showed that food production varied substantially with future land-use choices and management, and its trade-offs with water quality and soil retention persisted under most scenarios. However, pathways to mitigate or even reverse such trade-offs through technological advances and sustainable agricultural practices were apparent. Consistent relationships among regulating services were identified across scenarios (e.g., trade-offs of freshwater supply vs. flood and climate regulation, and synergies among water quality, soil retention, and climate regulation), suggesting opportunities and challenges to sustaining these services. In particular, proactive

    Nuclear energy must be made available, freely and readily, to help meet world energy needs, concerns over energy price and security of supply, and alleviating the uncertainties over potential climate change. The perspective offered here is a model for others to consider, adopting and adapting using whatever elements fit their own strategies and needs. The underlying philosophy is to retain flexibility in the reactor development, deployment and fuel cycle, while ensuring the principle that customer, energy market, safety, non-proliferation and sustainability needs are all addressed. Canada is the world's largest exporter of uranium, providing about one-third of the world supply for nuclear power reactors. Pressure tube reactors (PTRs), of which CANDU, is a prime example, have a major role to play in a sustainable energy future. The inherent fuel cycle flexibility of the PTR offers many technical, resource and sustainability and economic advantages over other reactor technologies and is the subject of this paper. The design evolution and development intent is to be consistent with improved or enhanced safety, licensing and operating limits, global proliferation concerns, and waste stream reduction, thus enabling sustainable energy futures. The limits are simply those placed by safety, economics and resource availability. (author)

    2015-11-01

    Deltas are increasingly under pressure from human impact and climate change. To deal with these pressures that threat future delta functioning, we need to understand interactions between physical, biological, chemical and social processes in deltas. This requires an integrated approach, in which knowledge on natural system functioning is combined with knowledge on spatial planning, land and water governance and legislative frameworks. In the research focus area Future Deltas of Utrecht University an interdisciplinary team from different research groups therefore works together. This allows developing integrated sustainable and resilient delta management strategies, which is urgently needed to prevent loss of vital delta services.

  1. Chinese villages and their sustainable future: the European Union-China-Research Project "SUCCESS".

    Science.gov (United States)

    Dumreicher, Heidi

    2008-04-01

    China has 800,000 villages-one person out of seven on the globe is living in a Chinese rural settlement. Yet the global discussions about the situation in China is currently characterised by a disproportionate focus on the development of towns and until now circumstances have generally been neglected in the rural areas, where 70% of the Chinese population is still living. Within the 5 years of the SUCCESS project research, this set of actual problems has been considered and analysed under the principle of sustainability: "What to maintain?" "What to change?" were the overall research questions asked in the SUCCESS project; the researchers were looking for answers under a sustainability regime, respecting the need to raise the quality of life in the villages. Several interweaving processes were used to achieve results: the inter-disciplinary research process between many areas of expertise, the trans-disciplinary process between the researchers and the Chinese villagers, and a negotiation process that made the connection between these two processes. The introduction describes the basic sustainability definition that was orienting the whole study. The innovation lays mostly in the methodology: the inter-disciplinary research co-operation related to practice and to involving the affected communities is needed to manage the significant and growing imbalances between urban and rural areas regarding their sustainability. In the transdisciplinary work, the project developed "village future sentences" that describe the local outcome of the research as one step towards better theoretical understanding of the mechanisms that could lead to a sustainable future, and they also managed to start sustainability processes in the case study sites. The integrated approach of the project helped generating future scenarios for these villages covering all aspects of their development, including urban design issues. Out of these scenarios, the villages developed small projects that could

    Romero-Lankao, P.

    2014-12-01

    The pace and scale of contemporary urbanization is a defining feature of the Anthropocene, which characterizes the dominance of human influence on the global environment. Although urban areas occupy less than three percent of the global land surface, they have global-scale impacts on natural resources, social dynamics, human wellbeing and the environment. The global environmental changes already underway are profound and in some ways irreversible. Altogether, these have serious implications for future human and environmental health, and social wellbeing. Despite considerable research and policy attention to cities, efforts are strongly needed towards integration that builds upon this and facilitates intensive interactions among disciplines in developing new perspectives, theory and methods for understanding urbanizations and urban systems as they drive and are affected by global environmental change, and for exploring options to achieve sustainability and resilience in an urbanizing world. I will present initial outcomes from a 2014 NSF/Future Earth-funded activity to develop a co-designed and interdisciplinary urban initiative within the Future Earth framework. The complexity of urban systems and the global sustainability challenges we face require inter- and trans-disciplinary research approaches that adopt a contextual approach to finding solutions. I will synthesize perspectives spanning multiple urban research and practice communities from workshops that took place over 2014 including the 2104 UGEC Conference, where emphasis was given to exploring: knowledge gaps and key urban research and socially-relevant questions moving forward; major challenges and opportunities for developing conceptual and methodological frameworks that support the global transformation to sustainability in the context of an urbanizing planet; operational mechanisms that must be in place for a successful interdisciplinary urban project that fits within Future Earth.

    Over the last few years, the world has seen growing concern about the sustainability of the Planet when supplying increasing energy use. The major issues are: increased energy prices in the world markets; growing energy demand in emerging economies; security and stability of oil and gas supply; potentially adverse climate change due to carbon-based emissions; and the need to deploy economic, sustainable and reliable alternates. Large undefined 'wedges' of alternate energy technologies are needed. In light of these major difficulties, there is renewed interest and need for a greater role for nuclear energy as a safe, sustainable and economic energy contributor. The shift has been, from being viewed by some as politically discounted, to being accepted as absolutely globally essential. We have carefully considered, and systematically, extensively and technically analyzed the contributions that nuclear energy can and should make to a globally sustainable energy future. These include restraining emissions, providing safe and secure power, operating synergistically with other sources, and being both socially and fiscally attractive. Therefore, we quantify in this paper the major contributions: a) The reduction in climate change potential and the global impact of future nuclear energy deployment through emissions reduction, using established analysis tools which varying the plausible future penetration and scale of nuclear energy. b) The minimization of economic costs and the maximization of global benefits, including investment requirements, carbon price implications, competitive market penetration, and effect of variable daily pricing. c) The introduction of fuel switching, including base-load nuclear energy synergistically enabling both hydrogen production and the introduction of significant wind power. d) The management and reduction of waste streams, utilizing intelligent designs and fuel cycles that optimize fuel resource use and minimize emissions, waste disposal

    Kenyan Young Generation in Nuclear (KYGN) hosted the inaugural African Youth Nuclear Summit, dubbed AYNS2017 that took place on the 27th to 30th March, 2017, Nairobi, Kenya. The participants were drawn from academia, research and development institutes, radiation services providers, health institutions, nuclear facilities and regulatory bodies. They shared experiences, exchanged ideas and built networks on issues related to safe application of nuclear science and technology. The theme of the summit was ''Nuclear for a Sustainable future'', which centered on three thematic areas: Nuclear powering Africa, Radiation Protection and safety culture; and application of nuclear science and technology for a sustainable future. The Director General, World Nuclear Association who pointed out that nuclear energy had made a major contribution to world energy output and was set to increase by two and half time by 2040. The importance of nuclear science and technology for a sustainable socio-economic development in Africa shared and highlight on many areas IAEA has helped member states in improving the life of its populations. The main activities of project 60 whose focus is to strengthen the nuclear security culture in East and Central Africa through improved regulation, training, capacity and awareness were highlighted

  5. Transformative Learning for a Sustainable Future: An Exploration of Pedagogies for Change at an Alternative College

    Full Text Available Educators and policy makers have long recognised the central role that education can play in creating a more sustainable and equitable world. Yet some question whether current processes across mainstream higher education prepare learners sufficiently to graduate with the capabilities or motivation to shape and create a future that is life-sustaining. This paper presents findings from a qualitative research project carried out by Plymouth University in association with Schumacher College, Devon, UK. Schumacher College is an alternative, civil society college, owned by the Dartington Hall Trust that claims to provide transformative learning opportunities within a broad context of sustainability. The study explored the nature and application of transformative learning as a pedagogical approach to advance change towards sustainability. If learners claimed transformational learning experiences, the research asked whether, and to what extent, this transformation could be attributed to the pedagogies employed at the College. The paper begins by setting out the broad background to the relationship between marginal and mainstream educational settings, and definitions and theoretical underpinnings of transformative learning, and then leads into the research design and findings. The potential for transformative pedagogies to be applied to and employed within the wider higher education (HE sector is then discussed, and the overall findings and conclusions are presented.

  6. Building a Sustainable Energy Future for Africa - Acting Now and Together

    The key energy challenges Africa is facing are: low level of access to commercial energy, low per capita energy consumption, weak development of energy infrastructure and lack of investment and financing for energy projects. Addressing these challenges is critical for sustainable economic and social development, and assured access to secure, affordable and reliable energy. In spite of these daunting challenges, Africa is well endowed in energy resources, but these resources are largely untapped and concentrated in a few countries. In addition, there are numerous 'rooms' for opportunities that could be seized concretely to overcome the main obstacles to the Sustainable Energy Development of the Continent. Thus, right actions must be taken to overcome these obstacles, including: financing the huge needed investments, technological development, private-public partnerships, energy market reform and effective regulation, sound and sustainable energy policies, and economic and social measures. Subsequently, from priority areas, the related stakeholders should 'act now' and 'act together', through effective collaboration and partnership and making proper alliances, to initiate effective and concrete actions to support Africa aspirations in order to build a Sustainable Energy Future for Africa, in a cost-effective and timely manner.

    2008-02-01

    This paper presents the local institutional and organizational development insights from a five-year ongoing interdisciplinary research project focused on advancing the implementation of sustainable urban water management. While it is broadly acknowledged that the inertia associated with administrative systems is possibly the most significant obstacle to advancing sustainable urban water management, contemporary research still largely prioritizes investigations at the technological level. This research is explicitly concerned with critically informing the design of methodologies for mobilizing and overcoming the administrative inertia of traditional urban water management practice. The results of fourteen in-depth case studies of local government organizations across Metropolitan Sydney primarily reveal that (i) the political institutionalization of environmental concern and (ii) the commitment to local leadership and organizational learning are key corporate attributes for enabling sustainable management. A typology of five organizational development phases has been proposed as both a heuristic and capacity benchmarking tool for urban water strategists, policy makers, and decision makers that are focused on improving the level of local implementation of sustainable urban water management activity. While this investigation has focused on local government, these findings do provide guideposts for assessing the development needs of future capacity building programs across a range of different institutional contexts.

    The empirical study, in this article, involved 42 students (ages 14-15), who used the urban simulation computer game SimCity 4 to create models of sustainable future cities. The aim was to explore in what ways the simulated "real" worlds provided by this game could be a potential facilitator for science learning contexts. The topic investigated is in what way interactions in this gaming environment, and reflections about these interactions, can form a context where the students deal with real world problems, and where they can contextualise and apply their scientific knowledge. Focus group interviews and video recordings were used to gather data on students' reflections on their cities, and on sustainable development. The findings indicate that SimCity 4 actually contributes to creating meaningful educational situations in science classrooms, and that computer games can constitute an important artefact that may facilitate contextualisation and make students' use of science concepts and theories more explicit.

    Developing sustainable energy systems is a key driver for mitigating the global climate change in the framework of COP21 conference commitments. Nuclear energy is strongly concerned by such a perspective and we have developed a thorough approach to define relevant objectives to fulfill in order to meet such a requirement. On this basis nuclear energy systems need to be improved to increase the preservation of uranium natural resource and reduce their environmental footprints. It requires in both cases increasing energetic material recycling based first on the current LWR reactor fleet, in the future on SFR which would allow a much more efficient use of neutrons to consume uranium and produce energy. Furthermore, such reactor type would also allow minor actinides recycling, which would significantly reduce the ultimate waste toxicity and lifetime, and the repository footprint. In this perspective, recycling the actinides is clearly the cornerstone of any sustainable nuclear fuel cycle

    In 2002 we published Rocky Mountain Futures, an Ecological Perspective (Island Press) to examine the cumulative ecological effects of human activity in the Rocky Mountains. We concluded that multiple local activities concerning land use, hydrologic manipulation, and resource extraction have altered ecosystems, although there were examples where the “tyranny of small decisions” worked in a positive way toward more sustainable coupled human/environment interactions. Superimposed on local change was climate change, atmospheric deposition of nitrogen and other pollutants, regional population growth, and some national management policies such as fire suppression.

    2008-11-01

    Full Text Available In order to be able to help students to read nature and to get an ability to discern both biodiversity in different contexts and changes in the environment we need to investigate how they experience biodiversity and how they discern different components in an ecosystem. Therefore, we undertook an interview-study of fifteen 10-12 year old students’ experiences of biodiversity and how they discerned organisms in different ecosystems. We analysed how they described the organisms and how they referred to experiences from everyday life. After two years we interviewed the students about what they said in the initial interview. Experiences of biodiversity at an early age seemed to be important for the future development of their understanding. It is important, both to give children early experiences of biodiversity in nature and to take students’ early ideas into consideration in teaching for lifelong learning and for a sustainable future.

  17. Turning points towards sustainability: integrative science and policy for novel (but real landscape futures

    2004-09-01

    Full Text Available Non-metropolitan landscapes are the major theatre of interactions where large-scale alteration occurs precipitated by local to global forces of economic, social and environmental change. However, these regional landscape effects are critical also to local natural resource and social sustainability, ecosystem health through to larger scales of biospheric functioning. The institutions contributing pressures and responses consequently shape future landscapes and in turn influence how social systems, resource users, governments and policy makers perceive those landscapes and their future. These are, in essence, complex social-ecological systems intertwined in a multitude of ways at many spatial scales across time. Over time, the cycles of complex social-ecological systems also reach crossroads, which might be crisis points at which future options are no longer available (possibly because of resource degradation or loss, or turning points where opportunities arise when it is easier to change direction towards more sustainable activities. This paper provides some examples of interdisciplinary research that has provided a holistic integration through close engagement with residents and communities or through deliberately implementing integrative high-risk ‘on-ground’ experimental models to ‘learn by doing’. In the final analysis, each project has characteristically, however, sought to integrate through spatial (if not temporal synthesis, policy analysis and (new or changed institutional arrangements that are relevant locally and corporately, as well as at broader levels of government and geography. This has provided transferable outcomes that can contribute real options and adaptive capacity for suitable positive futures.

    2018-01-01

    Phenolic Impregnated Carbon Ablator (PICA), invented in the mid 1990's, is a low-density ablative thermal protection material proven capable of meeting sample return mission needs from the moon, asteroids, comets and other unrestricted class V destinations as well as for Mars. Its low density and efficient performance characteristics have proven effective for use from Discovery to Flag-ship class missions. It is important that NASA maintain this thermal protection material capability and ensure its availability for future NASA use. The rayon based carbon precursor raw material used in PICA preform manufacturing has experienced multiple supply chain issues and required replacement and requalification at least twice in the past 25 years and a third substitution is now needed. The carbon precursor replacement challenge is twofold - the first involves finding a long-term replacement for the current rayon and the second is to assess its future availability periodically to ensure it is sustainable and be alerted if additional replacement efforts need to be initiated. This paper reviews current PICA sustainability activities to identify a rayon replacement and to establish that the capability of the new PICA derived from an alternative precursor is in family with previous versions.

  19. A multi evaporator desalination system operated with thermocline energy for future sustainability

    KAUST Repository

    2017-05-05

    All existing commercial seawater desalination processes, i.e. thermally-driven and membrane-based reverse osmosis (RO), are operated with universal performance ratios (UPR) varying up to 105, whilst the UPR for an ideal or thermodynamic limit (TL) of desalination is at 828. Despite slightly better UPRs for the RO plants, all practical desalination plants available, hitherto, operate at only less than 12% of the TL, rendering them highly energy intensive and unsustainable for future sustainability. More innovative desalination methods must be sought to meet the needs of future sustainable desalination and these methods should attain an upper UPR bound of about 25 to 30% of the TL. In this paper, we examined the efficacy of a multi-effect distillation (MED) system operated with thermocline energy from the sea; a proven desalination technology that can exploit the narrow temperature gradient of 20°C all year round created between the warm surface seawater and the cold-seawater at depths of about 300–600m. Such a seawater thermocline (ST)-driven MED system, simply called the ST-MED process, has the potential to achieve up to 2 folds improvement in desalination efficiency over the existing methods, attaining about 18.8% of the ideal limit. With the major energy input emanated from the renewable solar, the ST-MED is truly a “green desalination” method of low global warming potential, best suited for tropical coastal shores having bathymetry depths of 300m or more.

  20. Urbanisation-Induced Land Cover Temperature Dynamics for Sustainable Future Urban Heat Island Mitigation

    Directory of Open Access Journals (Sweden)

    Andrew MacLachlan

    2017-12-01

    Full Text Available Urban land cover is one of the fastest global growing land cover types which permanently alters land surface properties and atmospheric interactions, often initiating an urban heat island effect. Urbanisation comprises a number of land cover changes within metropolitan regions. However, these complexities have been somewhat neglected in temperature analysis studies of the urban heat island effect, whereby over-simplification ignores the heterogeneity of urban surfaces and associated land surface temperature dynamics. Accurate spatial information pertaining to these land cover change—temperature relationships across space is essential for policy integration regarding future sustainable city planning to mitigate urban heat impacts. Through a multi-sensor approach, this research disentangles the complex spatial heterogeneous variations between changes in land cover (Landsat data and land surface temperature (MODIS data, to understand the urban heat island effect dynamics in greater detail for appropriate policy integration. The application area is the rapidly expanding Perth Metropolitan Region (PMR in Western Australia (WA. Results indicate that land cover change from forest to urban is associated with the greatest annual daytime and nighttime temperature change of 0.40 °C and 0.88 °C respectively. Conversely, change from grassland to urban minimises temperature change at 0.16 °C and 0.77 °C for annual daytime and nighttime temperature respectively. These findings are important to consider for proposed developments of the city as such detail is not currently considered in the urban growth plans for the PMR. The novel intra-urban research approach presented can be applied to other global metropolitan regions to facilitate future transition towards sustainable cities, whereby urban heat impacts can be better managed through optimised land use planning, moving cities towards alignment with the 2030 sustainable development goals and the City

    national and international trends have identified concerns over the ability of health and social care workforces in meeting the needs of service users. Attention has increasingly been drawn to problems of recruiting and retaining professionals within higher education; however data in relation to the midwifery profession is scant. to examine the perceptions and experiences of midwifery educators, in south-west England, about the challenges facing them sustaining the education workforce of the future. a mixed methodology approach was adopted involving heads of midwifery education and midwife educators. midwifery participants were recruited from three higher education institutions in south west England. Data collection comprised of self-administered questionnaires plus individual qualitative interviews with heads of midwifery education (n=3), and tape recorded focus groups with midwife academics (n=19). Numerical data were analysed using descriptive statistics. Textual data were analysed for themes that represented the experiences and perspectives of participants. Ethics approval was granted by one University Ethics committee. demographic data suggests that within south-west England, there is a clear ageing population and few in possession of a doctorate within midwifery. The six identified sub-themes represented in the data describe challenges and tensions that midwifery academics experienced in their efforts to attract new recruits and retain those in post in a highly changing educational environment which demands more from a contracting workforce. there remain some serious challenges facing midwifery educators in sustaining the future education workforce, which if unresolved may jeopardise standards of education and quality of care women receive. Active succession planning and more radical approaches that embrace flexible careers will enable educational workforce to be sustained and by a clinically credible and scholarly orientated midwifery workforce.

    2015-03-01

    Companion animals play an important role in our lives and are now considered to be and treated as family members in a majority of households in the United States. Because of the high number of pets that now exist, an increasingly stronger pet-human bond, and the importance placed on health and longevity, the pet food industry has realized steady growth over the last few decades. Despite past successes and opportunities that exist in the future, there are also challenges that must be considered. This review will present a brief overview of the current pet food industry and address some of the key issues moving forward. In regards to companion animal research, recent advances and future needs in the areas of canine and feline metabolism, aging, clinical disease, and the gut microbiome using molecular and high-throughput assays; chemical, in vitro, and in vivo testing of feed ingredients; and innovative pet food processing methods is discussed. Training the future workforce for the pet food industry is also of great importance. Recent trends on student demographics and their species and careers of interest, changing animal science department curricula, and technology's impact on instruction are provided. Finally, the sustainability of the pet food industry is discussed. Focus was primarily placed on the disconnect that exists between opinions and trends of consumers and the nutrient recommendations for dogs and cats, the desire for increasing use of animal-based and human-grade products, the overfeeding of pets and the pet obesity crisis, and the issues that involve the evaluation of primary vs. secondary products in terms of sustainability. Moving forward, the pet food industry will need to anticipate and address challenges that arise, especially those pertaining to consumer expectations, the regulatory environment, and sustainability. Given the already strong and increasingly dynamic market for pet foods and supplies, an academic environment primed to supply a

  3. Nuclear power and sustainable development. Maintaining and increasing the overall assets available to future generations

    International Nuclear Information System (INIS)

    2002-01-01

    A central goal of sustainable development is to maintain or increase the overall assets available to future generations, while minimizing consumption of finite resources and not exceeding the carrying capacities of ecosystems. The development of nuclear power broadens the natural resource base usable for energy production, increases human and man-made capital, and, when safely handled, has little impact on ecosystems. Energy is essential for sustainable development. With continuing population and economic growth, and increasing needs in the developing world, substantially greater energy demand is a given, even taking into account continuing and accelerated energy efficiency and intensity improvements. Today, nuclear power is mostly utilized in industrialized countries that have the necessary technological, institutional and financial resources. Many of the industrialized countries that are able and willing to use nuclear power are also large energy consumers. Nuclear power currently generates 16% of the world's electricity. It produces virtually no sulfur dioxide, particulates, nitrogen oxides, volatile organic compounds or greenhouse gases. Globally, nuclear power currently avoids approximately 600 million tonnes of carbon emissions annually, about the same as hydropower. The 600 MtC avoided by nuclear power equals 8% of current global greenhouse gases emissions. In the OECD countries, nuclear power has for 35 years accounted for most of the reduction in the carbon intensity per unit of delivered energy. Existing operating nuclear power plants (NPPs) for which initial capital investments are largely depreciated are also often the most cost-effective way to reduce carbon emissions from electricity generation. In fact in the United States in 2000, NPPs were the most cost-effective way to generate electricity, irrespective of avoided carbon emissions. In other countries the advantages of existing nuclear generating stations are also increasingly recognized. Interest

    2017-09-01

    NASA's Sustainable Land Imaging (SLI) program, managed through the Earth Science Technology Office, aims to develop technologies that will provide future Landsat-like measurements. SLI aims to develop a new generation of smaller, more capable, less costly payloads that meet or exceed current imaging capabilities. One projects funded by this program is Ball's Compact Hyperspectral Prism Spectrometer (CHPS), a visible-to-shortwave imaging spectrometer that provides legacy Landsat data products as well as hyperspectral coverage suitable for a broad range of land science products. CHPS exhibits extremely low straylight and accommodates full aperture, full optical path calibration needed to ensure the high radiometric accuracy demanded by SLI measurement objectives. Low polarization sensitivity in visible to near-infrared bands facilitates coastal water science as first demonstrated by the exceptional performance of the Operational Land Imager. Our goal is to mature CHPS imaging spectrometer technology for infusion into the SLI program. Our effort builds on technology development initiated by Ball IRAD investment and includes laboratory and airborne demonstration, data distribution to science collaborators, and maturation of technology for spaceborne demonstration. CHPS is a three year program with expected exiting technology readiness of TRL-6. The 2013 NRC report Landsat and Beyond: Sustaining and Enhancing the Nations Land Imaging Program recommended that the nation should "maintain a sustained, space-based, land-imaging program, while ensuring the continuity of 42-years of multispectral information." We are confident that CHPS provides a path to achieve this goal while enabling new science measurements and significantly reducing the cost, size, and volume of the VSWIR instrument.

    A growing global population, combined with factors such as changing socio-demographics, will place increased pressure on the world's resources to provide not only more but also different types of food. Increased demand for animal-based protein in particular is expected to have a negative environmental impact, generating greenhouse gas emissions, requiring more water and more land. Addressing this "perfect storm" will necessitate more sustainable production of existing sources of protein as well as alternative sources for direct human consumption. This paper outlines some potential demand scenarios and provides an overview of selected existing and novel protein sources in terms of their potential to sustainably deliver protein for the future, considering drivers and challenges relating to nutritional, environmental, and technological and market/consumer domains. It concludes that different factors influence the potential of existing and novel sources. Existing protein sources are primarily hindered by their negative environmental impacts with some concerns around health. However, they offer social and economic benefits, and have a high level of consumer acceptance. Furthermore, recent research emphasizes the role of livestock as part of the solution to greenhouse gas emissions, and indicates that animal-based protein has an important role as part of a sustainable diet and as a contributor to food security. Novel proteins require the development of new value chains, and attention to issues such as production costs, food safety, scalability and consumer acceptance. Furthermore, positive environmental impacts cannot be assumed with novel protein sources and care must be taken to ensure that comparisons between novel and existing protein sources are valid. Greater alignment of political forces, and the involvement of wider stakeholders in a governance role, as well as development/commercialization role, is required to address both sources of protein and ensure food

    The collaborative Climate Science for a Sustainable Energy Future (CSSEF) project started in July 2011 with the goal of accelerating the development of climate model components (i.e., atmosphere, ocean and sea ice, and land surface) and enhancing their predictive capabilities while incorporating uncertainty quantification (UQ). This effort required accessing and converting observational data sets into specialized model testing and verification data sets and building a model development test bed, where model components and sub-models can be rapidly evaluated. CSSEF’s prototype test bed demonstrated, how an integrated testbed could eliminate tedious activities associated with model development and evaluation, by providing the capability to constantly compare model output—where scientists store, acquire, reformat, regrid, and analyze data sets one-by-one—to observational measurements in a controlled test bed.

    Various international dynamics are converging to increase the attractiveness of decentralized energy as a complement to existing centralized energy infrastructures. Decentralized energy (DE) technologies, including onsite renewables, high efficiency cogeneration and industrial energy recycling, offer considerable benefits to those seeking working alternatives to emerging challenges in the energy sector. DE is ideally suited to provide clean affordable energy to areas where modern energy services are currently lacking. Having smaller generators close to where energy is required ensures a safe, reliable and secure energy supply when the energy is required. Furthermore, because DE is a much cleaner alternative than conventional central power plants and the energy provided comes at a much smaller price tag DE is an increasingly acceptable alternative both in the developed and developing world. DE is sure to play a key role in any plan to build a sustainable energy future. (auth)

    Full Text Available The valorization of aquatic-derived biowastes as possible feedstock for the production of value-added chemicals and materials is proposed here as a sustainable alternative compared to the exploitation of the more conventional (fossil resources. In this context, the comprehension of the opportunity related to the valorization of the shellfish industry biowaste for the production of useful materials, especially focusing on chitin and its derived byproducts, is investigated. The large amount of waste produced each year by the shellfish processing industry seems to be an appealing opportunity for the European market to produce valuable products from underutilized waste. In order to highlight this important market-opportunity, the actual European situation concerning the shellfish volume of production is presented. The industrial processes necessary for the recovery of chitin, chitosan, and their derivatives are largely described, together with a wide description of their peculiar (and interesting physicochemical properties. Even if nowadays the scientific literature suggests that this class of biopolymers is very appealing, further research is still necessary for overcoming some criticisms still present in the extraction and valorization of such substrates. However, the principles of both circular economy and green chemistry encourage the reduction of such biowastes and their exploitation as an alternative resource for a global sustainable future.

    The world we are living in is shaped by what is a reality for years already: globalisation of economy. The lack of borders makes the impact that technology has on society to be a major one. The virtual world so accessible today is not just about new markets, access to cheaper work force, work online but also fierce competition. The common denominator of most efforts in the area of industry is performance. Limits continuously moving willingness to pay for products that delineate the performance delivered be the same range. Here too we can see the role of the education. For example, Landes shows that both knowledge and know-how are the ones that determine how well off societies are. The education of engineers is therefore critical to every nation to ensure the prosperity of its citizens. This paper here intends to approach the educational process of the engineering specific area of knowledge from the management perspective. The training process becomes sustainable in accordance with the requirements of the future: trained specialists for sustainable enterprises.

    Full Text Available Software Defined Networking (SDN has brought many changes in terms of the interaction processes between systems and humans. It has become the key enabler of software defined architecture, which allows enterprises to build a highly agile Information Technology (IT infrastructure. For Future Sustainability Computing (FSC, SDN needs to deliver on many information technology commitments—more automation, simplified design, increased agility, policy-based management, and network management bond to more liberal IT workflow systems. To address the sustainability problems, SDN needs to provide greater collaboration and tighter integration with networks, servers, and security teams that will have an impact on how enterprises design, plan, deploy and manage networks. In this paper, we propose FS-OpenSecurity, which is a new and pragmatic security architecture model. It consists of two novel methodologies, Software Defined Orchestrator (SDO and SQUEAK, which offer a robust and secure architecture. The secure architecture is required for protection from diverse threats. Usually, security administrators need to handle each threat individually. However, handling threats automatically by adapting to the threat landscape is a critical demand. Therefore, the architecture must handle defensive processes automatically that are collaboratively based on intelligent external and internal information.

    Full Text Available Dhaka, the capital of Bangladesh is one of the most populated megacity in the world and the population growth in this city is extremely high. To support growing food demand of increasing population, food supply should be secure and sustainable. On the other hand, with the pace of urbanization built-up areas are increasing; hence supply of roof space is also increasing. Rooftop farming can provide solution to increased food demand and also can promote a sustainable and livable city. Local fresh and safe food can be ensured through roof gardens in Dhaka city. The aim of the study is to explore the present practice and challenges of rooftop farming that was encountered by practitioners. Mirpur and Mohammadpur areas have been selected as study areas. Two practitioners are interviewed and 60 non-practitioners are surveyed. Results show that rooftop farming can support environment by improving air quality, reducing carbon in the atmosphere and can benefit society by reducing storm water management cost. One of the significant findings from the non-practitioner survey is that maximum people are willing to practice rooftop farming and want to provide at least 50% of roof space for rooftop farming. Finally some recommendations have been suggested to improve rooftop farming practice and encourage more people to practice rooftop farming in future.

    Following an intense deforestation process initiated in the 1960s, clear-cut deforestation rates in the Brazilian Amazon have decreased significantly since 2004. A convergence of conditions contributed to this, including the creation of protected areas, the use of effective monitoring and control systems, and credit restriction mechanisms. Although regional social indicators have also slightly improved, society remains unequal and violent, both in urban and rural areas. Furthermore, the combined results of the fall of deforestation and the increased economic importance of the agribusiness sector have led to the political weakening of the so-called socio-environmental model. Thus, the current situation indicates a future of low (clear-cut) carbon emissions and low social conditions. On the other hand, other threats remain, including forest degradation derived from illegal logging and forest fires. There is also considerable uncertainty about the fate of the remaining forest areas as multiple forces can contribute to the return of high deforestation, including the rapidly expanding global markets for agricultural commodities, large-scale transportation and energy infrastructure projects, and weak institutions. We present the results of a participatory scenario process, in which we discussed the future of the region until 2050 combining normative and exploratory approaches. We include an ideal "Sustainability" scenario (Scenario A) in which we envision major socioeconomic, institutional and environmental achievements. Scenario B stays in the "Middle of the road", in which the society maintains some of the positive environmental trends of the last decade, but not reversing the structural situation of social inequities. Scenario C is a pessimistic vision, named "Fragmentation" with high deforestation rates and low social development. The goal of the work was twofold: (a) to propose a method to enrich the discussion among different private and governmental stakeholders

    Working and sporting dogs provide an essential contribution to many industries worldwide. The common development, maintenance and disposal of working and sporting dogs can be considered in the same way as other animal production systems. The process of 'production' involves genetic selection, puppy rearing, recruitment and assessment, training, housing and handling, handler education, health and working life end-point management. At present, inefficiencies throughout the production process result in a high failure rate of dogs attaining operational status. This level of wastage would be condemned in other animal production industries for economic reasons and has significant implications for dog welfare, as well as public perceptions of dog-based industries. Standards of acceptable animal use are changing and some historically common uses of animals are no longer publicly acceptable, especially where harm is caused for purposes deemed trivial, or where alternatives exist. Public scrutiny of animal use appears likely to increase and extend to all roles of animals, including working and sporting dogs. Production system processes therefore need to be transparent, traceable and ethically acceptable for animal use to be sustainable into the future. Evidence-based approaches already inform best practice in fields as diverse as agriculture and human athletic performance. This article introduces the nascent discipline of canine performance science, which aims to facilitate optimal product quality and production efficiency, while also assuring evidence-based increments in dog welfare through a process of research and development. Our thesis is that the model of canine performance science offers an objective, transparent and traceable opportunity for industry development in line with community expectations and underpins a sustainable future for working dogs.

    The rapid rise in technologies for data collection has created an unmatched opportunity to advance the use of data-rich tools for lifecycle decision-making. However, the usefulness of these technologies is limited by the ability to translate lifecycle data into actionable insights for human decision-makers. This is especially true in the case of sustainable lifecycle design (SLD), as the assessment of environmental impacts, and the feasibility of making corresponding design changes, often relies on human expertise and intuition. Supporting human sense-making in SLD requires the use of both data-driven and user-driven methods while exploring lifecycle data. A promising approach for combining the two is through the use of visual analytics (VA) tools. Such tools can leverage the ability of computer-based tools to gather, process, and summarize data along with the ability of human-experts to guide analyses through domain knowledge or data-driven insight. In this paper, we review previous research that has created VA tools in SLD. We also highlight existing challenges and future opportunities for such tools in different lifecycle stages-design, manufacturing, distribution & supply chain, use-phase, end-of-life, as well as life cycle assessment. Our review shows that while the number of VA tools in SLD is relatively small, researchers are increasingly focusing on the subject matter. Our review also suggests that VA tools can address existing challenges in SLD and that significant future opportunities exist.

  1. Fit for the Future? A New Approach in the Debate about What Makes Healthcare Systems Really Sustainable

    2014-12-01

    Full Text Available As healthcare systems face enormous challenges, sustainability is seen as a crucial requirement for making them fit for the future. However, there is no consensus with regard to either the definition of the term or the factors that characterize a “sustainable healthcare system”. Therefore, the aim of this article is twofold. First, it gives examples of the existing literature about sustainable healthcare systems and analyzes this literature with regard to its understanding of sustainability and the strengths and weaknesses of the different approaches. The article then identifies crucial factors for sustainable healthcare systems, and the result, a conceptual framework consisting of five distinct and interacting factors, can be seen as a starting point for further research.

    In response to concerns regarding the environmental impacts of the current energy resource mix, significant research efforts have been focused on determining the future energy resource mix to meet emissions reduction and environmental sustainability goals. Many of these studies focus on various constraints such as costs, grid operability requirements, and environmental performance, and develop different plans for the rollout of energy resources between the present and future years. One aspect that has not yet been systematically taken into account in these planning studies, however, is the potential impacts that changing climates may have on the availability and performance of key energy resources that compose these plans. This presentation will focus on a case study for California which analyzes the impacts of climate change on the greenhouse gas emissions and renewable resource utilization of an energy resource plan developed by Energy Environmental Economics for meeting the state's year 2050 greenhouse gas goal of 80% reduction in emissions by the year 2050. Specifically, climate change impacts on three aspects of the energy system are investigated: 1) changes in hydropower generation due to altered precipitation, streamflow and runoff patterns, 2) changes in the availability of solar thermal and geothermal power plant capacity due to shifting water availability, and 3) changes in the residential and commercial electric building loads due to increased temperatures. These impacts were discovered to cause the proposed resource plan to deviate from meeting its emissions target by up to 5.9 MMT CO2e/yr and exhibit a reduction in renewable resource penetration of up to 3.1% of total electric energy. The impacts of climate change on energy system performance were found to be mitigated by increasing the flexibility of the energy system through increased storage and electric load dispatchability. Overall, this study highlights the importance of taking into account and

    Melbourne Water has adopted a challenging target of recycling 20 per cent of treated effluent from Melbourne's two major sewerage treatment plants by 2010. This target was adopted in response to key drivers for water recycling in the Melbourne region such as: strong support for conserving water resources and protecting marine environments; acknowledgment of recycled water as a valuable resource; greater emphasis on environmental issues and sustainable management principles; and opportunities to increase demand for recycled water through effective planning mechanisms. Issues that must be effectively addressed to meet the target include: managing public perceptions of recycled water; health and environmental concerns; lack of consensus among government agencies; high up-front costs of infrastructure; and prices of other sources of water supply not currently true costed. Melbourne Water has identified the following factors as critical in determining the success of recycling strategy: ability to demonstrate that water recycling will be important in terms of long term water cycle management; effective stakeholder consultation; gaining government support; establishing long-term, guaranteed markets for recycled water; implementing well planned, large scale recycling schemes; ability to provide a product that meets customer needs; regulatory approval; and implementation of a system that is economically viable. Water recycling initiatives are being investigated on household, local and regional levels. Over 10 proposals that will contribute to the 20 per cent recycled water target from the regional treatment plants are under various stages of development. Melbourne Water's commitment to recycling within a total water cycle management context is a vital component of this major new initiative for Melbourne and is crucial for a sustainable future.

    This case study on nanotechnology with a focus on sustainable water management was done within the scope of the research project ''Future markets - innovative environmental policy in important fields of action''. Nanotechnology is a broad cross-cutting technology with a multitude of process and technology platforms. Nanotechnologies can contribute to preventing water pollution (e. g. by substituting water polluting processes) or removing this (e. g. nanomaterials/ membranes in wastewater treatment) and can be used to monitor water quality (e. g. nanosensors). Water plays a key role in nutrition and health, in agriculture (irrigation) and as a solvent in industrial processes. A globally sustainable supply of drinking water and industrial water is seen as one of the main challenges of the next decades. The world water supply market is predicted to be more than 400 billion US-$ (2010), in which membrane technologies will play a key role. The rapid development of nanotechnologies is reflected in the constant growth in the number of nanotechnology patents and publications. New types of filtration membranes and nanomaterials for the catalytic, adsorptive or magnetic-separation purification of wastewater constitute an important segment; some marketable products have already been developed in this field. In the long term, convergence in the fields of electronics, biotechnology, nanotechnology and microsystems will offer new perspectives and applications, in sustainable water management as well. Germany has high technological competence in membrane and nanofiltration technology, mostly based on the strength of its basic research, which can serve as a good basis from which to tap foreign markets. The USA is the leader in the field of nanotechnology and in water management applications. Starting points for policy measures are the initiation and implementation of innovationsupporting measures for the further development of these technologies -particularly

    Interactions and feedbacks between rapidly increasing multiple pressures on water, energy and food security drive social-ecological systems at multiple scales towards critical thresholds in countries of the Eastern Mediterranean, the Middle East and North Africa (MENA Region). These pressures, including climate change, the growing demand on resources and resource degradation, urbanization and globalization, cause unprecedented challenges for countries and communities in the region. Responding to these challenges requires integrated science and a closer relationship with policy makers and stakeholders. Future Earth has been designed to respond to these urgent needs. In order to pursue such objectives, Future Earth is becoming the host organization for some 23 programs that were previously run under four global environmental change programmes, DIVERSITAS, the International Geosphere-Biosphere Programme (IGBP), the International Human Dimensions Programme (IHDP) and the World Climate Research Programme (WCRP). Some further projects arose out of the Earth System Science Partnership (ESSP). It thus brings together a wide spectrum of expertise and knowledge that will be instrumental in tackling urgent problems in the MENA region and the wider Mediterranean Basin. Future Earth is being administered by a globally distributed secretariat that also includes a series of Regional Centers, which will be the nuclei for the development of new regional networks. The Cyprus Institute in Nicosia, Cyprus (CyI; www.cyi.ac.cy) is hosting the Regional Center for the MENA Region. The CyI is a non-profit research and post-graduate education institution with a strong scientific and technological orientation and a distinctive regional, Eastern Mediterranean scope. Cyprus at the crossroads of three continents and open to all nations in the region provides excellent conditions for advancing the research agenda of Future Earth in the MENA Region.

    Maria Christina Georgiadou

    2014-09-01

    Full Text Available Under the label “future-proofing”, this paper examines the temporal component of sustainable construction as an unexplored, yet fundamental ingredient in the delivery of low-energy domestic buildings. The overarching aim is to explore the integration of future-proofed design approaches into current mainstream construction practice in the UK, focusing on the example of the Code for Sustainable Homes (CSH tool. Regulation has been the most significant driver for achieving the 2016 zero-carbon target; however, there is a gap between the appeal for future-proofing and the lack of effective implementation by building professionals. Even though the CSH was introduced as the leading tool to drive the “step-change” required for achieving zero-carbon new homes by 2016 and the single national standard to encourage energy performance beyond current statutory minima, it lacks assessment criteria that explicitly promote a futures perspective. Based on an established conceptual model of future-proofing, 14 interviews with building practitioners in the UK were conducted to identify the “feasible” and “reasonably feasible” future-proofed design approaches with the potential to enhance the “Energy and CO2 Emissions” category of the CSH. The findings are categorised under three key aspects; namely: coverage of sustainability issues; adopting lifecycle thinking; and accommodating risks and uncertainties and seek to inform industry practice and policy-making in relation to building energy performance.

    2013-12-01

    The development of shale oil and gas reserves over the last several years has had a significant impact on securing America's energy future while making substantial contributions to our nation's economic prosperity. These developments have also raised serious concerns about potential detrimental impacts to our environment (i.e., land, air and water) with much media attention focused on the impacts to our nation's fresh water supply. These concerns are being discussed across the nation often with little or no distinction that the nature of the water issues vary depending on local circumstances (e.g., depth of aquifer and reservoir zone, water demand and availability, availability of discharge wells, regulatory framework, etc.) and regional shale reservoir development strategies (depth of wells, length of laterals, fluid-type used for fracturing, etc.). Growing concerns over long standing drought conditions in some areas and competing demands for water from other sectors (e.g., agriculture, domestic, etc.) add even greater uncertainty relative to fresh water. Water demands for gas and oil wells vary from region to region but nominally range from 10 to 15 acre feet of water (4 to 6 million gallons) for drilling and hydraulic fracturing applications. Flowback water from the hydraulic fracturing process varies and can range from 5 to 40 % of the water used for drilling and 'fracing'. Produced water can be substantial, leading to significant volumes of 'disposed water' where injection wells are available. A science-based systems approach to water lifecycle management that incorporates leading-edge technology development and considers economic and social impacts is critical for the long-term sustainable development of shale reserves. Various water recycling and reuse technologies are being deployed within select regions across the nation with each having limited success depending on region. The efficacy of reuse technology will vary based on produced water quantity and

    2003-01-01

    The Hydrogen Economy encompasses the production of hydrogen using a wide range of energy sources, its storage and distribution as an economic and universal energy carrier, and its end use by industry and individuals with negligible emission of pollutants and greenhouse gases. Hydrogen is an energy carrier not a primary energy source, just like electricity is an energy carrier. The advantages of hydrogen as a means of storage and distribution of energy, and the methods of production of hydrogen, are reviewed. Energy sources for hydrogen production include fossil fuels, renewables, hydropower and nuclear power. Hydrogen has many applications in industry, for residential use and for transport by air, land and sea. Fuel cells are showing great promise for conversion of hydrogen into electricity and their development and current status are discussed. Non-energy uses of hydrogen and the safety aspects of hydrogen are also considered. It is concluded that the Hydrogen Economy, especially if coupled to renewable and nuclear energy sources, is a technically viable and economic way of achieving greater energy diversity and security and a sustainable future in this century

As a result, the value of existing assets is changing globally depending on the scarcity, necessity and effects on the business field leading to increased prices of traditional sources of energy and increased competition in the economic field. Thus, the EU energy market has progressed in reducing its dependence on external energy sourcing, by increasing production of renewable energy, such as wind or solar, as well as by further integration of the electric grid. Based on the Pearson coefficient this article intends to research the correlations between the economic, energy and house prices in recent years and the future possible impacts depending on their evolution. For example, gas prices in the past decade increasing household costs in most countries due to the dependence on third parties for energy, lead to the need of increasing the share of renewable energy in total energy consumption, which have consequently decreased electricity prices since 2008. However, this development has still not solved the additional costs issue of households due to the new technologies implemented although wind and solar energy receive in general low margins. Such energy issues, as well as the increased housing prices after the financial crisis in 2008 have caused on their own an additional burden on the economy and households spending income in the next years following.

    Environmental pollution and greenhouse gas emissions are becoming significant environmental issues in China, thus the sustainable development and revival of the country is impossible using the conventional path of encouraging economic growth at the expense of the environment. In response to the global warming, the prices of the traditional energy rise considerably, and a series of environmental problems, China must improve its own mode of economic development. Hundreds of Chinese cities have billions of square meters of buildings and most industry and the annual energy demand is an astronomical figure. China's government is facing increasing pressure in the low carbon international backdrop, and the low carbon city becomes the inevitable developmental direction of Chinese city in the foreseeable future. The description is first centered on energy structure/energy consumption per unit/urbanized status, and urban energy consumption status, and then concerned with the efforts and measures of Chinese government, to realize the energy saving. Finally, we present the developmental prospect and barriers and the promotion measures related to the low carbon city under the government policy, financial incentives and funding supports, etc.

    Full Text Available Positive youth development outcomes are influenced by a competent, highly trained work force that enjoys their work with young people. The youth work field has struggled with how to keep and motivate front line youth workers given the heavy workloads, low pay, lack of recognition and irregular time demands to compete with family responsibilities. Professional development is a key strategy for retaining and motivating youth workers. A model of professional development called the Western 4-H Institute has been developed and held now for two sessions. Results from participants indicate that this strategy can have a positive influence on job satisfaction, competencies, and retention. In fact, only 10 percent of participants had left during the intervening 5 years, and job satisfaction had increased significantly over time. Organizational loyalty among participants is not high, but with early career professionals, they may still be trying to find their niche. A regional training model has shown itself to be effective in supporting 4-H youth professionals and is building a sustainable workforce for the future.

    Full Text Available Earth observation data can provide valuable assessments for monitoring the spatial extent of (unsustainable urban growth of the world’s cities to better inform planning policy in reducing associated economic, social and environmental costs. Western Australia has witnessed rapid economic expansion since the turn of the century founded upon extensive natural resource extraction. Thus, Perth, the state capital of Western Australia, has encountered significant population and urban growth in response to the booming state economy. However, the recent economic slowdown resulted in the largest decrease in natural resource values that Western Australia has ever experienced. Here, we present multi-temporal urban expansion statistics from 1990 to 2015 for Perth, derived from Landsat imagery. Current urban estimates used for future development plans and progress monitoring of infill and density targets are based upon aggregated census data and metrics unrepresentative of actual land cover change, underestimating overall urban area. Earth observation provides a temporally consistent methodology, identifying areal urban area at higher spatial and temporal resolution than current estimates. Our results indicate that the spatial extent of the Perth Metropolitan Region has increased 45% between 1990 and 2015, over 320 km2. We highlight the applicability of earth observation data in accurately quantifying urban area for sustainable targeted planning practices.

    Cinema Metropole XXI is one of the heritage buildings located in the heart of Menteng area, with “art deco” architecture. The appereance of this building is very beautiful and very impressed from other buildings, become strong Icon around the Menteng neighborhood. In 2010 the building was bought by Cinema 21, where the physical condition is very messy and looks slum. The emergence of modern shopping and entertainment centers are also complete with cinema facilities are more comfortable and complete, While the atmosphere of this old cinema is considered uncomfortable for visitors, so slowly abandoned by customers. The status of the cultural heritage inherent in this building becomes an obstacle by owners to renew this building, until the cinema closes in some time. The loss of the long-standing potential of cultural heritage buildings due to the transformation of urban development is an important issue in this paper, this case study is the author’s experience in regenerating the future potential at this heritage building. This writing is done by Descriptive Analysis method from various reference approaches and theory of cultural heritage values involved in the restoration of Metropole XXI cinema. The conclusions of this paper find a real solution to problem solving for the sustainability of this building.

  18. Future sustainability forecasting by exchange markets: basic theory and an application.

    2010-12-01

    Setting sustainability targets and evaluating systems progress are of great importance nowadays due to threats to the human society, to economic development and to ecosystems, posed by unsustainable human activities. This research establishes a probabilistic theoretical approach based on market expectations reflected in prices of publicly traded securities to estimate the time horizon until the appearance of new technologies related to replacement of nonrenewable resources, for example, crude oil and oil products. To assess time T when technological innovations are likely to appear, we apply advanced pricing equations, based on a stochastic discount factor to those traded securities whose future cash flows critically depend on appearance of such innovations. In a simple approximation of the proposed approach applied to replacement of crude oil and oil products, we obtain T ≈ (P(0)(oil)/C(0))·ln (Δ·P(0)(oil)/P(0)(alt)), where P(0)(oil) and P(0)(alt) are the current aggregate market capitalizations of oil and alternative-energy companies, C(0) is the annual aggregate dividends that oil companies pay to their shareholders at the present, and Δ is the fraction of the oil (oil products) replaced at time T. This formula gives T ≈ 131 years for replacement of gasoline and diesel. The proposed market-expectations approach may allow policymakers to effectively develop policies and plan for long-term changes.

    Full Text Available Tracking the environmental impacts of production, use, and disposal of products (e.g., goods, and services have been an important issue in the global economy. Although Life Cycle Assessment (LCA is a widely applied method to track these environmental impacts and support policies, it has certain limitations and an isolated way of evaluating the environmental impacts with no consideration of social and economic impacts and mechanisms. To overcome the limits of current LCA, three mechanisms have been proposed in the literature: (1 broadening the indicators by including social and economic indicators in addition to the environmental impacts; (2 broadening the scope of analysis from product-level assessment to national and global levels; (3 deepening the assessment by inclusion of more mechanisms to account for interrelations among the system elements, uncertainty analysis, stakeholder involvement, etc. With these developments, LCA has been evolving into a new framework called Life Cycle Sustainability Assessment (LCSA. Practical application of LCSA requires integration of various methods, tools, and disciplines. In this study, a comprehensive literature review is conducted to investigate recent developments, current challenges, and future perspectives in the LCSA literature. According to the review, a high number (40% of LCSA studies are from the environmental science discipline, while contributions from other disciplines such as economics (3% and social sciences (9% are very low. On broadening the scope of analysis, 58% of the studies are product-level works, while 37% quantified the impacts at national level and achieved an economy-wide analysis, and only 5% of the studies were able to quantify the global impacts of products using LCSA framework. Furthermore, current applications of LCSA have not considered the rebound effects, feedback mechanisms, and interrelations of the system of interest sufficiently. To address these challenges, we present a

    2011-02-01

    Within the project NEEDS (New Energy Externalities Development for Sustainability) a range of criteria and indicators were defined according to the widely recognised 'three pillar' interpretation of sustainable development in order to assess future electricity generating technologies including their associated fuel cycles. The basic characteristics of the 26 technologies were defined as being appropriate in 2050 according to 'realistic/optimistic' development scenarios. The potential environmental impacts of each technology were assessed by initially determining the various criteria necessary to describe the range of significant impact areas. These criteria were then expressed and measured by one or more quantifiable indicators which were calculated using Life Cycle Inventories established earlier in the project. This report contributed to Research Stream RS2b of the project by quantifying and comparing the results of these indicators for each of the four countries used in the assessment: France, Germany, Switzerland and Italy. The environmental assessment showed that the nuclear technologies cause relatively very low impacts according to most of the indicators. The Generation IV, European Fast Reactor, has significant advantages over the European Pressurised Reactor but the availabilities of the two reactors will be quite different. Whereas the first examples of the EPR are already under construction, the design finalisation of the EFR is not yet complete meaning that the first plant is not expected to be constructed before 2040. An overarching and clear distinction between the fossil fueled technologies was less possible and the application of carbon capture and storage, whilst showing large reductions in greenhouse gas emissions, was shown to be counteracted in a number of other indicators. The integration of solid fuel gasification prior to combustion also showed both benefits and disadvantages. For most indicators, the natural gas combined cycle options

    2018-02-01

    Full Text Available The establishment of the UN Sustainable Development Goals (SDGs bolstered momentum to achieve a sustainable future. Undeniably, the welfare of future generations is a fundamental value of sustainable development since the publication of the Brundtland report. Nevertheless, SDGs and their targets are meagre on intergenerational justice concerns. The 15-year target horizon of the SDGs might be beneficial for implementation reasons. However, such a short-term perspective is far from innocuous in justice terms. It jeopardises the establishment of long-term goals, which protect both present and future people. This article advocates for clearer stances on intergenerational justice. What type of distributive principles could and should dictate the present socio-economic development? Looking at intragenerational justice principles contained in SDGs does not provide a full answer since they express conflicting visions of what constitutes a fair development. Furthermore, a fair distribution of the development benefits and burdens among present and near future people does not necessarily guarantee the wellbeing of more distant generations. I propose an intergenerational sufficientarian perspective as a way of extending the beneficial impacts of SDGs to both close and distant future generations. Hopefully, it facilitates the translation of the SDGs into policies that promote fairer implementation strategies.

  3. A climatic and environmental protection strategy, the road toward a sustainable future

    International Nuclear Information System (INIS)

    Bach, W.

    1994-01-01

    This editorial essay conveys a clear message: The overuse of our fossil fuel resources especially in the North, and the overpopulation in many parts of the South, result in an unacceptable stress to Earth. This manifests itself in some of the most serious threats to mankind, such as global climatic change, environmental degradation, food shortage, hunger, poverty, and migration. It is the purpose of this editorial essay to make a contribution toward a reduction of some of these threats, notably those from climatic change. Specifically, the paper presents a tractable climatic and environmental protection strategy which is designed to give concrete answers to such seemingly simple questions as: What has to be done? (This depends e.g. on the concentration stabilization objective of the Rio Climate Convention, and the global warming ceiling of the Enquete-Commission of the German Parliament). By whom does it have to be done? (This addresses the secret of a successful protection strategy which involves a fair burden sharing among the world's countries). When does it have to be done? (This discusses the problem of setting tractable, i.e. differentiated and binding emission targets). How can it be done? (This relates to individual countries, states, and municipalities. It is demonstrated for Germany how her commitment of a 25 to 30% CO 2 reduction by 2005 can be achieved). Moreover, the question is addressed: How many people and how much fossil fuel use can our planet stand? The major result is that without self-restraint climate and ecosystem cannot be maintained, because it is incompatible with trends in the wasteful fossil fuel use in the North and strong population growth in the South. Finally, a plea is made to share responsibility on the road toward a sustainable future. 32 refs., 4 tabs

    Combined Heat and Power (CHP) solutions represent a proven and effective near-term energy option to help the United States enhance energy efficiency, ensure environmental quality, promote economic growth, and foster a robust energy infrastructure. Using CHP today, the United States already avoids more than 1.9 Quadrillion British thermal units (Quads) of fuel consumption and 248 million metric tons of carbon dioxide (CO{sub 2}) emissions annually compared to traditional separate production of electricity and thermal energy. This CO{sub 2} reduction is the equivalent of removing more than 45 million cars from the road. In addition, CHP is one of the few options in the portfolio of energy alternatives that combines environmental effectiveness with economic viability and improved competitiveness. This report describes in detail the four key areas where CHP has proven its effectiveness and holds promise for the future as an: (1) Environmental Solution: Significantly reducing CO{sub 2} emissions through greater energy efficiency; (2) Competitive Business Solution: Increasing efficiency, reducing business costs, and creating green-collar jobs; (3) Local Energy Solution: Deployable throughout the US; and (4) Infrastructure Modernization Solution: Relieving grid congestion and improving energy security. CHP should be one of the first technologies deployed for near-term carbon reductions. The cost-effectiveness and near-term viability of widespread CHP deployment place the technology at the forefront of practical alternative energy solutions such as wind, solar, clean coal, biofuels, and nuclear power. Clear synergies exist between CHP and most other technologies that dominate the energy and environmental policy dialogue in the country today. As the Nation transforms how it produces, transports, and uses the many forms of energy, it must seize the clear opportunity afforded by CHP in terms of climate change, economic competitiveness, energy security, and infrastructure

  14. Planning for sustainable tourism in southern Pulau Banggi: an assessment of biophysical conditions and their implications for future tourism development.

    Teh, Lydia; Cabanban, Annadel S

    2007-12-01

    A priori assessments of a site's biophysical and socio-economic capacity for accommodating tourism are less common than tourism impact studies. A priori evaluations can provide a contextual understanding of ecological, economic and socio-cultural forces, which shape the prospects for sustainable tourism development at the host destination, and can avert adverse impacts of tourism. We conduct an a priori assessment of the biophysical environment of Pulau Banggi, in the Malaysian state of Sabah for sustainable tourism development. We characterise baseline conditions of the island's marine biodiversity, seasonality, and infrastructure. We then evaluate how existing biophysical conditions will influence options for sustainable tourism development. In particular, we suggest conditions, if there are any, which constitute a limit to future tourism development in terms of compatibility for recreation and resilience to visitor impacts. We find that the biggest constraint is the lack of adequate water and sanitation infrastructure. Blast fishing, although occurring less than once per hour, can potentially destroy the major attraction for tourists. We conclude that while Pulau Banggi possesses natural qualities that are attractive for ecotourism, financial and institutional support must be made available to provide facilities and services that will enable local participation in environmental protection and enhance prospects for future sustainable tourism.

  18. The 'sustainability lens': a framework for nurse education that is 'fit for the future'.

    Science.gov (United States)

    Goodman, Benny; East, Linda

    2014-01-01

    In this paper we describe and justify a framework for curriculum development that uses the concept of a sustainability lens. This is based on an understanding that we construct our social worlds and create a reality based upon what Gadamer (1977) called 'prejudices'. The social world of nurse education has its own prejudices, referred to by Scrimshaw (1983) as 'ideologies'. These form often taken for granted assumptions and values about what education is. The framework bases itself on how sustainability conceptualises health, and 4 approaches to health care delivery, along two continua of individual-society and illness-wellbeing. Further, we argue that in response to a wider education for sustainability agenda, nurse educators could develop their own sustainability lens and bring it to bear on this framework to interpret professional standards in a new way.

    In the framework of one of the fundamental objectives of the IAEA mandate to enhance the contribution of nuclear technologies towards meeting the needs of Member States, the present status, all the aspects, and the future of nuclear power are reviewed. The development of nuclear power broadens the natural resource base usable for energy production, increases human and man-made capital, and when safely handled has little impact on ecosystems. This means that it could meet the central goal of sustainable development, considering that it covers maintaining or increasing the overall assets available to future generations, while minimizing consumption of finite resources and not exceeding the carrying capacities of ecosystems

    To determine the level of community concern about future food supplies and perception of the importance placed on government regulation over the supply of environmentally friendly food and identify dietary and other factors associated with these beliefs in Western Australia. Data from the 2009 and 2012 Nutrition Monitoring Survey Series computer-assisted telephone interviews were pooled. Level of concern about the effect of the environment on future food supplies and importance of government regulating the supply of environmentally friendly food were measured. Multivariate regression analysed potential associations with sociodemographic variables, dietary health consciousness, weight status and self-reported intake of eight foods consistent with a sustainable diet. Western Australia. Community-dwelling adults aged 18-64 years (n = 2832). Seventy nine per cent of Western Australians were 'quite' or 'very' concerned about the effect of the environment on future food supplies. Respondents who paid less attention to the health aspects of their diet were less likely than those who were health conscious ('quite' or 'very' concerned) (OR = 0.53, 95% CI [0.35, 0.8] and 0.38 [0.17, 0.81] respectively). The majority of respondents (85.3%) thought it was 'quite' or 'very' important that government had regulatory control over an environmentally friendly food supply. Females were more likely than males to rate regulatory control as 'quite' or 'very' important' (OR = 1.63, 95% CI [1.09, 2.44], p = .02). Multiple regression modeling found that no other factors predicted concern or importance. There is a high level of community concern about the impact of the environment on future food supplies and most people believe it is important that the government regulates the issue. These attitudes dominate regardless of sociodemographic characteristics, weight status or sustainable dietary behaviours. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Full Text Available Increasingly, sustainability is conceived as a crisis of the human mind and the key challenge for pro-sustainability education is developing sufficient motivation in learners. The spiritual aspirations of religious communities contain sufficient motivational force, which may be deployed for effective sustainability education. This paper explores the approaches to sustainability and sustainability education of some internationally-oriented Hindu religious movements. These include the rural education initiatives of Gandhian Sarvodaya, which emphasizes non-harming, self-reliance and personal ethics, ISKCON, which emphasizes devotional service, P.R. Sarkar’s Ananda Marg, which emphasizes cooperative enterprise, the Tantric body re-imagined at the social scale, and Swami Vivekananda’s Sri Ramakrishna Order, which emphasizes karma yoga, spiritual development through service to the God in each human. It also describes the British Hindu contribution to the UNDP/ARC’s multi-faith sustainability initiative “Many Heavens, One Earth”; which is the “Bhumi Project” and its two main campaigns, Green Temples and Compassionate Living.

The relationship between corporate sustainable practices and financial performance has received growing attention in research, yet a consensus remains elusive. This paper identifies developing trends and the issues that hinder conclusive consensus on that relationship. We used content analysis to examine the literature and establish the current state of research. A total of 132 papers from top-tier journals are shortlisted. We find that 78% of publications report a positive relationship between corporate sustainability and financial performance. Variations in research methodology and measurement of variables lead to the divergent views on the relationship. Furthermore, literature is slowly replacing total sustainability with narrower corporate social responsibility (CSR, which is dominated by the social dimension of sustainability, while encompassing little to nothing of environmental and economic dimensions. Studies from developing countries remain scarce. More research is needed to facilitate convergence in the understanding of the relationship between corporate sustainable practices and financial performance.

    2012-01-01

    Background The introduction of evidence-based programs and practices into healthcare settings has been the subject of an increasing amount of research in recent years. While a number of studies have examined initial implementation efforts, less research has been conducted to determine what happens beyond that point. There is increasing recognition that the extent to which new programs are sustained is influenced by many different factors and that more needs to be known about just what these factors are and how they interact. To understand the current state of the research literature on sustainability, our team took stock of what is currently known in this area and identified areas in which further research would be particularly helpful. This paper reviews the methods that have been used, the types of outcomes that have been measured and reported, findings from studies that reported long-term implementation outcomes, and factors that have been identified as potential influences on the sustained use of new practices, programs, or interventions. We conclude with recommendations and considerations for future research. Methods Two coders identified 125 studies on sustainability that met eligibility criteria. An initial coding scheme was developed based on constructs identified in previous literature on implementation. Additional codes were generated deductively. Related constructs among factors were identified by consensus and collapsed under the general categories. Studies that described the extent to which programs or innovations were sustained were also categorized and summarized. Results Although "sustainability" was the term most commonly used in the literature to refer to what happened after initial implementation, not all the studies that were reviewed actually presented working definitions of the term. Most study designs were retrospective and naturalistic. Approximately half of the studies relied on self-reports to assess sustainability or elements that

    As one of the most important clean energy sources, proton exchange membrane fuel cells (PEMFCs) have been a topic of extensive research focus for decades. Unfortunately, several critical technique obstacles, such as the high cost of platinum electrode catalysts, performance degradation due to the CO poisoning of the platinum anode, and carbon corrosion by oxygen in the cathode, have greatly impeded its commercial development. A prototype of a single PEMFC catalyzed by a mesostructured platinum-free WO3/C anode and a mesostructured carbon-free Pt/WC cathode catalysts is reported herein. The prototype cell exhibited 93% power output of a standard PEMFC using commercial Pt/C catalysts at 50 and 70 °C, and more importantly, CO poisoning-free and carbon corrosion-resistant characters of the anode and cathode, respectively. Consequently, the prototype cell demonstrated considerably enhanced cell operation durability. The mesostructured electrode catalysts are therefore highly promising in the future development and application of PEMFCs. Copyright © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    2015-07-01

    Full Text Available This article reflects on the concept of “global citizenship” from a transdisciplinary methodology and a biomimetic approach. A sustainable human image appears with this epistemological symbiosis, that constitutes the DNA of a genuine tool of civilizational transformation. On the one hand, the transdisciplinary methodology is opened to the multi-referential conception of the three pillars proposed by Basarab Nicolescu (2008: levels of reality, logic of the included middle, and complexity. On the other hand, the concept of biomimicry approached by Janine M. Benyus (2012 identifies nine operating principles of life in order to mimic nature in the reformulation of new sustainable human production systems with the biosphere. The aim of this study is to identify international agreements on environmental and sustainable development, to elaborate some contribution in the post-2015 eco-political-educational strategic framework led by the United Nations with the Sustainable Development Goals. With the purpose of strengthening ties between education and sustainability through symbiotic bridges between nature and culture, the work identifies the vital axises that constitute the interdependence of ecosystems to make a biomimetic application in the social, political, and educational structures of human systems. Then, this paper is an innovational research that seeks to integrate the eco-ethics as a practice in the “Global Citizenship Education” proposed for UNESCO for next decade 2015-2025.

    The present study comprehensively reviews emergy analysis and performance evaluation of biomass energy. Biomass resources utilization technologies include (a) bioethanol production, (b) biomass for bio-oil, (c) biodiesel production, (d) straw as fuel in district heating plants, (e) electricity from Municipal Solid Waste (MSW) incineration power plant, (f) electricity from waste landfill gas. Systems diagrams of biomass, which are to conduct a critical inventory of processes, storage, and flows that are important to the system under consideration and are therefore necessary to evaluate, for biomasses are given. Emergy indicators, such as percent renewable (PR), emergy yield ratio (EYR), environmental load ratio (ELR) and environmental sustainability index (ESI) are shown to evaluate the environmental load and local sustainability of the biomass energy. The emergy indicators show that bio-fuels from crop are not sustainable and waste management for fuels provides an emergy recovery even lower than mining fossil fuel.

    2018-04-01

    Full Text Available Sustainable ventures often lack legitimacy (perceived to be desirable and appropriate because various stakeholder groups use contradictory institutions (rules and norms to make their judgements, which leads to there being fewer resources available and higher failure rates. Using an institutional theory framework and a multi-case research design with 15 biofuel ventures operating in the Netherlands, this study asks how sustainable entrepreneurs attempt to gain legitimacy in these circumstances. Analysis reveals that the entrepreneurs use a combination of rhetorical, reconciliatory and institutional change strategies to obtain legitimacy from different stakeholder groups. These findings further our understanding of sustainable entrepreneurial behavior by revealing how and why different legitimation strategies are used in complex institutional environments.

  14. Plant diversity and conservation in China: planning a strategic bioresource for a sustainable future.

    China is one of the richest countries for plant diversity with approximately 33 000 vascular plant species, ranking second in the world. However, the plant diversity in China is increasingly threatened, with an estimated 4000–5000 plant species being threatened or on the verge of extinction, making China, proportionally, one of the highest priorities for global plant biodiversity conservation. Coming in the face of the current ecological crisis, it is timely that China has launched China's Strategy for Plant Conservation (CSPC). China has increasingly recognized the importance of plant diversity in efforts to conserve and sustainably use its plant diversity. More than 3000 nature reserves have been established, covering approximately 16% of the land surface of China. These natural reserves play important roles in plant conservation, covering more than 85% of types of terrestrial natural ecosystems, 40% of types of natural wetlands, 20% of native forests and 65% of natural communities of vascular plants. Meanwhile, the flora conserved in botanical gardens is also extensive. A recent survey shows that the 10 largest botanical gardens have living collections of 43 502 taxa, with a total of 24 667 species in ex situ conservation. These provide an important reserve of plant resources for sustainable economic and social development in China. Plant diversity is the basis for bioresources and sustainable utilization. The 21st century is predicted to be an era of bio-economy driven by advances of bioscience and biotechnology. Bio-economy may become the fourth economy form after agricultural, industrial, and information and information technology economies, having far-reaching impacts on sustainable development in agriculture, forestry, environmental protection, light industry, food supply and health care and other micro-economy aspects. Thus, a strategic and forward vision for conservation of plant diversity and sustainable use of plant resources in the 21st century is of

  18. Community action for sustainable housing: Building a low-carbon future

    International Nuclear Information System (INIS)

    Seyfang, Gill

    2010-01-01

    This paper presents a new analytical framework of 'grassroots innovations' which views community-led initiatives for sustainable development as strategic green niches with the potential for wider transformation of mainstream society. This framework is applied to a low-carbon, low-impact, community-based sustainable housing initiative in the USA that pioneers straw bale housing techniques within a strong community-building ethos. The project is evaluated according to New Economics criteria of sustainable consumption, and is found to be successful at localising the construction supply chain, reducing ecological footprints, community-building, enabling collective action and building new institutions and systems of provision around housebuilding. However, viewing it as a strategic niche with aim to influence wider society, it is clear that it faces significant challenges in diffusing its ideas and practices beyond the niche. Its model is not necessarily suitable for scaling up or widespread replication; however, the scope for niche lessons to be adopted by mainstream builders is greater, given a supportive policy environment. Recognising the innovative nature of green niches at the policy level could lead to new approaches to governance of bottom-up community action for sustainable development.

  3. Sustainable Wastewater Management: Is it Possible to Regulate Micropollution in the Future by Learning from the Past? A Policy Analysis

    Directory of Open Access Journals (Sweden)

    Florence Metz

    2014-04-01

    Full Text Available This paper applies a policy analysis approach to the question of how to effectively regulate micropollution in a sustainable manner. Micropollution is a complex policy problem characterized by a huge number and diversity of chemical substances, as well as various entry paths into the aquatic environment. It challenges traditional water quality management by calling for new technologies in wastewater treatment and behavioral changes in industry, agriculture and civil society. In light of such challenges, the question arises as to how to regulate such a complex phenomenon to ensure water quality is maintained in the future? What can we learn from past experiences in water quality regulation? To answer these questions, policy analysis strongly focuses on the design and choice of policy instruments and the mix of such measures. In this paper, we review instruments commonly used in past water quality regulation. We evaluate their ability to respond to the characteristics of a more recent water quality problem, i.e., micropollution, in a sustainable way. This way, we develop a new framework that integrates both the problem dimension (i.e., causes and effects of a problem as well as the sustainability dimension (e.g., long-term, cross-sectoral and multi-level to assess which policy instruments are best suited to regulate micropollution. We thus conclude that sustainability criteria help to identify an appropriate instrument mix of end-of-pipe and source-directed measures to reduce aquatic micropollution.

    Energy independence and security of supplies, improved safety standards, sustainably optimised material management, minimal waste production - all without greenhouse gas emissions. These are the Generation IV International Forum specifications for nuclear energy of the future. The CEA is responsible for designing Astrid, an integrated technology demonstrator for the 4. generation of sodium-cooled fast reactors, in accordance with the French Sustainable Nuclear Materials and Waste Management Act of June 28, 2006, and funded as part of the Investments for the Future programme enacted by the French parliament in 2010. Energy management - a vital need and a factor of economic growth - is a major challenge for the world of tomorrow. The nuclear industry has significant advantages in this regard, although it faces safety, resource sustainability, and waste management issues that must be met through continuing technological innovation. Fast reactors are also of interest to the nuclear industry because their recycling capability would solve a number of problems related to the stockpiles of uranium and plutonium. After the resumption of R and D work with EDF and AREVA in 2006, the Astrid design studies began in 2010. The CEA, as owner and contracting authority for this programme, is now in a position to define the broad outlines of the demonstrator 4. generation reactor that could be commissioned during the next decade. A sodium-cooled fast reactor (SFR) operates in the same way as a conventional nuclear reactor: fission reactions in the atoms of fuel in the core generate heat, which is conveyed to a turbine generator to produce electricity. In the context of 4. generation technology, SFRs represent an innovative solution for optimising the use of raw materials as well as for enhancing safety. Here are a few ideas advanced by the CEA.

    In the debate on sustainable energy future, the role of nuclear power is a contentious issue. Many, who are outside of the nuclear community, do not even consider nuclear, because of public concerns on nuclear safety, radioactive waste and non-proliferation issues. For example, the United Nations Development Program, in its document Energy After Rio does not suggest a specific role for nuclear power except in the most doubtful of terms. On the contrary, most nuclear organisations and related industries see nuclear power as the only mature carbon-free electricity generating option that can be deployed even on a much larger scale than today. This paper analyses the potential role of nuclear power in the context of the global sustainable energy future. The fundamental features of sustainable energy development are examined in terms of the following compatibility constraints: Demand driven compatibility; Natural resource compatibility; Environmental compatibility; Geopolitical compatibility; and Economic compatibility

    Increased urbanization worldwide has resulted in a substantial increase in energy and material consumption as well as anthropogenic waste generation. The main source for our current needs is petroleum refinery, which have grave impact over energy-environment nexus. Therefore, production of bioenergy and biomaterials have significant potential to contribute and need to meet the ever increasing demand. In this perspective, a biorefinery concept visualizes negative-valued waste as a potential renewable feedstock. This review illustrates different bioprocess based technological models that will pave sustainable avenues for the development of biobased society. The proposed models hypothesize closed loop approach wherein waste is valorised through a cascade of various biotechnological processes addressing circular economy. Biorefinery offers a sustainable green option to utilize waste and to produce a gamut of marketable bioproducts and bioenergy on par to petro-chemical refinery. Copyright © 2016 Elsevier Ltd.

    2016-04-01

    Climate change, increase in population and intensification of land use pose a great challenge for sustainable handling of soils. Intelligent landuse systems are able to minimize and/or avoid soil erosion and loss of soil fertility. A successful application of such systems requires area-wide soil information with high resolution. Containing three consecutive steps, the project INE-2-H („innovative sustainable landuse") at the University of Tuebingen is about creating high-resolution soil information using Digital Soil Mapping (DSM) techniques to develop sustainable landuse strategies. Input data includes soil data from fieldwork (texture and carbon content), the official digital soil and geological map (1:50.000) as well as a wide selection of local, complex and combined terrain parameters. First, soil maps have been created using the DSM approach and Random Forest (RF). Due to high resolution (10x10 m pixels), those maps show a more detailed spatial variability of soil information compared to the official maps used. Root mean square errors (RMSE) of the modelled maps vary from 2.11 % to 6.87 % and the coefficients of determination (R²) go from 0.42 to 0.68. Second, soil erosion potentials have been estimated according to the Universal Soil Loss Equation (USLE). Long-term average annual soil loss ranges from 0.56 to 24.23 [t/ha/a]. Third, combining high-resolution erosion potentials with expert-knowledge of local farmers will result in a landuse system adapted to local conditions. This system will include sustainable strategies reducing soil erosion and conserving soil fertility.

    InTeGrate materials focus on societal grand challenges, sustainability, and interdisciplinary problems through developing geoscientific habits of mind, the use of credible data, and systems thinking. The materials are freely available 2-3 week modules and courses that allow instructors to focus on a wide variety of topics from regulating carbon emissions, changing biosphere, and storms and community resilience to environmental justice, ocean sustainability, and humans' dependence on mineral resources, integrating a variety of relevant interdisciplinary activities throughout. Presented with interdisciplinary approaches, students learn with tools to integrate engineering, policy, economics, and social aspects with the science to address the challenges. Students' ability to apply interdisciplinary approaches to address sustainability problems is made visible through the essays they write as a part of the materials assessment. InTeGrate modules have been adopted and implemented by faculty members interested in sustainability themes and innovative pedagogy, and have reached more than 50,000 students in all 50 states, Puerto Rico, India, and Micronesia. Student data were collected from 533 assessment essays in 57 undergraduate classes. The essays required students to describe a global challenge in an interdisciplinary manner through identifying scientific implications, and connecting it to economic, social and policy decisions. Students also completed a second essay assessing their systems thinking ability, a geoscience literacy exam (GLE), and demographic and attitudinal surveys. Scores for students enrolled in classes using InTeGrate materials were compared to scores from students in similar classes that did not use InteGrate materials. The InTeGrate and control groups had equivalent GLE scores and demographic characteristics. Essay scores for students in InTeGrate introductory or majors courses outperformed students in comparable level control courses as measured by

    Counselling services are recommended by the World Health Organization and have been partially adopted by national HIV guidelines. In settings with a high HIV burden, patient education and counselling is often performed by lay workers, mainly supported with international funding. There are few examples where ministries of health have been able to absorb lay counsellors into their health systems or otherwise sustain their work. We document the role of lay cadres involved in HIV testing and counselling and adherence support and discuss approaches to sustainability. We focused on a purposive sample of eight sub-Saharan African countries where Médecins Sans Frontières supports HIV programmes: Guinea, Lesotho, Malawi, Mozambique, South Africa, Swaziland, Zambia and Zimbabwe. We reviewed both published and grey literature, including national policies and donor proposals, and interviewed key informants, including relevant government staff, donors and non-governmental organizations. Lay counsellors play a critical role in scaling up HIV services and addressing gaps in the HIV testing and treatment cascade by providing HIV testing and counselling and adherence support at both the facility and community levels. Countries have taken various steps in recognizing lay counsellors, including harmonizing training, job descriptions and support structures. However, formal integration of this cadre into national health systems is limited, as lay counsellors are usually not included in national strategies or budgeting. The current trend of reduced donor support for lay counsellors, combined with lack of national prioritization, threatens the sustainability of this cadre and thereby quality HIV service delivery.

  20. Robust and sustainable bioenergy: Biomass in the future Danish energy system; Robust og baeredygtig bioenergi: Biomasse i fremtidens danske energisystem

    The publication is a collection of articles about new, exciting technologies for the production of bioenergy, which received support from Danish research programmes. The green technologies must be sustainable so that future generations' opportunities for bioenergy use is not restricted, and the solutions must be robust in relation to security of supply, costs and energy economy. In this context, research plays a crucial role. Research is especially carried out within the use of residues as bio-waste, straw, wood and manure for energy purposes, but there are also projects on energy crops, as well as research into how algae from the sea can increase the production of biomass.

    Full Text Available One of the next major challenges for research and policy on sustainability is setting the post-2015 Development Agenda. This challenge arises as a direct result of the formal ending of the Millennium Development Goals (MDGs in 2015 and as an outcome of the 2012 United Nations Conference on Sustainable Development (Rio+20. The post-2015 Development Agenda is expected to include two agendas: one on human well-being to advance the MDG targets and the other on planetary well-being, which requires a safe “operating space” within the Earth’s life-support system. In contrast to the MDGs, the Sustainable Development Goals (SDGs are meant to apply to both developing and developed countries and create a space for development within the stable functioning of the Earth’s systems. However, what might this all look like? For answers, this paper reviews the achievements and reflections of the MDGs to date and identifies new challenges entailed in the shift of development goals from “millennium” to “sustainable”. While most of the existing studies look at these two sets of issues separately, combining the two reveals two important features of the SDGs. First, SDGs need to integrate both human and planetary well-being in a goal, and second, goals, or sub-goals, need to be formulated at multiple levels, from global to local levels. While the MDGs represented no integrated goals, some of the existing proposals on SDGs include integrated goals. However, our analysis has shown that they do not present the vertical diffusion of goals. Considering both integration and diffusion in the architecture of SDGs is a remaining task.

    Banda Aceh experienced rapid growth, both physically, socially, and economically, after the Tsunami that devastated it the end of December in 2004. Hence policy controls are needed to direct the pattern of urban growth to achieve sustainable development for the future. The purpose of this paper is to generate a growth model for Banda Aceh using the CA-Markov process. By knowing the changes in land use between 2005 and 2009 from the results of previous research, simulations for 2013, 2019 and 2029 using the application of Idrisi@Selva. CA-Markov models were prepared to determine the quantity of changes. The simulation results showed that, after the Tsunami, the City of Banda Aceh tended to grow towards the coast. For the control of the LUC, the Banda Aceh City government needs to prepare comprehensive and detailed maps and inventory of LUC for the city to provide basic data and information needed for monitoring and evaluation that can be done effectively and efficiently. An institution for monitoring and evaluation of the urban landscape and the LUC should be formed immediately. This institution could consist of representatives from government, academia, community leaders, the private sector and other experts. The findings from this study can be used to start the monitoring and evaluation of future urban growth. Especially for the coastal areas, the local government should immediately prepare special spatial coastal area plans to control growth in those areas and to ensure that the economic benefits from disaster mitigation and coastal protection are preserved. For the development of the city in the future, it is necessary to achieve a balance between economic development, and social welfare with environmental protection and disaster mitigation. iIt will become a big challenge to achieve sustainable development for the future.

  5. On the Feasibility of a Timely Transition to a More Sustainable Energy Future

    Directory of Open Access Journals (Sweden)

    Micha Tomkiewicz

    2010-01-01

    Full Text Available The paper uses the framework of the IPAT equation, as applied to CO2 emission, to decompose the various driving forces in the global energy use. Data from recent history are superimposed on projections of SRES IPCC scenarios to determine if enough sustainable capacity can be built to prevent irreversible ecological deterioration. The conclusion from the analysis is that, in agreement with the IPCC 4th report, until about 2030 there are no large differences between a sustainable scenario and the one that resembles “business as usual”. The sharp divergence that follows stems from different estimates in population growth and in the percentage of use of fossil fuels in the total energy mix. Decomposition of alternative energy options indicate that the rate of increase of alternatives such as hydroelectric and nuclear start with a relatively high base but a growth rate too short for major contribution to a timely replacement of fossil fuels while wind and solar starts from a much lower base but rate of growth, if maintained, that can satisfy a timely replacement.

    Today, we are undertaking great efforts to improve biomass production and quality traits of energy crops. Major motivation for developing those crops is based on environmental and ecological sustainability considerations, which however often are de-coupled from the trait-based crop improvement programs. It is now time to develop appropriate methods to link crop traits to production system characteristics set by the plant and the biotic communities influencing it; and to the ecosystem processes affecting ecological sustainability. The relevant ecosystem processes involve the net productivity in terms of biomass and energy yields, the depletion of energy-demanding resources (e.g., nitrogen, N), the carbon dynamics in soil and atmosphere, and the resilience and temporal stability of the production system. In a case study, we compared aspects of N use efficiency in various varieties of an annual (spring wheat) and perennial (Salix) energy crop grown under two nutrient regimes in Sweden. For example, we found considerable variation among crops, varieties, and nutrient regimes in the energy yield per plant-internal N (megajoule per gram per year), which would result in different N resource depletion per unit energy produced.

    Raftery, Michael; Carter-Journet, Katrina

    2013-01-01

    The International Space Station (ISS) risk management methodology is an example of a mature and sustainable process. Risk management is a systematic approach used to proactively identify, analyze, plan, track, control, communicate, and document risks to help management make risk-informed decisions that increase the likelihood of achieving program objectives. The ISS has been operating in space for over 14 years and permanently crewed for over 12 years. It is the longest surviving habitable vehicle in low Earth orbit history. Without a mature and proven risk management plan, it would be increasingly difficult to achieve mission success throughout the life of the ISS Program. A successful risk management process must be able to adapt to a dynamic program. As ISS program-level decision processes have evolved, so too has the ISS risk management process continued to innovate, improve, and adapt. Constant adaptation of risk management tools and an ever-improving process is essential to the continued success of the ISS Program. Above all, sustained support from program management is vital to risk management continued effectiveness. Risk management is valued and stressed as an important process by the ISS Program.

    Beyond its hydrocarbon resources, Algeria has a high potential of renewable energy which it has the ambition to develop with foreign partners. The development of renewable energies corresponds to the option of a sustainable development. Independently of the units of solar energy intended to feed the remote centers, projects of renewable energies connected to the national grid are in course of development. Our strategy consists in carrying out a synergy between the Solar one and the natural gas thanks to gas/solar hybrid projects by profiting from the Algerian natural gas endowment and to the permanent sunshining of the South of the country. A first gas/solar hybrid project, of large capacity, is under development. Its realization will bring a significant solar energy contribution to the national energy balance and will constitute a first experiment, on a large scale, in the production of renewable electricity connected to the grid of national distribution. This communication focuses on the strategy and efforts made by Algeria to promote renewable energies within the framework of the sustainable development with as objective bringing the share of the electricity produced by renewable energies to 5 % of the total electricity produced from by 2010.

    2014-12-01

    As it supplies solar power, a priori considered harmless for the environment and human health compared with fossil fuels, the photovoltaic (PV) industry seems to contribute optimally to reduce greenhouse gas emissions and, overall, to sustainable development. However, considering the forecast for rapid growth, its use of potentially toxic substances and manufacturing processes presenting health and safety problems may jeopardize its benefits. This paper aims to establish a profile of the PV industry in order to determine current and emerging environmental and health concerns. A review of PV system life cycle assessments, in light of the current state of the industry and its developmental prospects, reveals information deficits concerning some sensitive life cycle indicators and environmental impacts, together with incomplete information on toxicological data and studies of workers' exposure to different chemical and physical hazards. Although solar panel installation is generally considered relatively safe, the occupational health concerns related to the growing number of hazardous materials handled in the PV industry warrants an all-inclusive occupational health and safety approach in order to achieve an optimal equilibrium with sustainability. To prevent eco-health problems from offsetting the benefits currently offered by the PV industry, manufacturers should cooperate actively with workers, researchers and government agencies toward improved and more transparent research, the adoption of specific and stricter regulations, the implementation of preventive risk management of occupational health and safety and, lastly, greater responsibilization toward PV systems from their design until their end of life.

    2017-12-12

    This paper evaluates current stakeholder involvement (SI) practices in science through a web-based survey among scholars and researchers engaged in sustainability or transition research. It substantiates previous conceptual work with evidence from practice by building on four ideal types of SI in science. The results give an interesting overview of the varied landscape of SI in sustainability science, ranging from the kinds of topics scientists work on with stakeholders, over scientific trade-offs that arise in the field, to improvements scientists wish for. Furthermore, the authors describe a discrepancy between scientists' ideals and practices when working with stakeholders. On the conceptual level, the data reflect that the democratic type of SI is the predominant one concerning questions on the understanding of science, the main goal, the stage of involvement in the research process, and the science-policy interface. The fact that respondents expressed agreement to several types shows they are guided by multiple and partly conflicting ideals when working with stakeholders. We thus conclude that more conceptual exchange between practitioners, as well as more qualitative research on the concepts behind practices, is needed to better understand the stakeholder-scientist nexus.

    Full Text Available The agribusiness topics ofcolored cottonand fashion do not have any practical scientific literature published on the subject,only when the theme is treated primarily as the aim of sustainability. Colored and agroecological cotton, despite the limitation in color,could become an industrial production with less environmental, impact using less water. The aim of this study was to present the colored fiber and organic cotton, produced by small farmers in the Northeast region of Brazil, as an alternative product to promote sustainability in cotton agribusiness and the textile industry, and to identify the lack of scientific studies related to the theme. Surveys were carried out on available national literature and international database publications on the topic, and the results of research on toxic products used for the production of white cotton and textile industry were presented. Governmental incentives through funding agencies to farmers engaged in this production are suggested, in order to improve production and distribution. It is also necessary to provide the infrastructure necessary for this product to reach the global market, including in cooperation with poorer countries in order to promote changes in environmental impact worldwide in the fashion industry

  13. Need for research and development in fusion: Economical energy for a sustainable future with low environmental impact

    Fusion, advanced fission, and solar-electric plants are the only unlimited nonfossil options for a sustainable energy future for the world. Fusion poses the only indigenous fuel reserve that will last as long as the earth itself lasts. However, continued innovation and diversity in fusion R ampersand D will be required to meet its economic goal. The long-term nature of fusion research means that the required R ampersand D investment will not come from the private sector. However, once fusion is realized commercially, the dividend for humanity will be profound in terms of the welfare of the global community. We should also not underestimate the huge potential export opportunities that would then open up for industry. Federal energy R ampersand D at nearly 1% of U.S. energy costs is prudent and justified to allow pursuit of all three primary energy options for a sustainable energy future. Multiple parallel paths are essential to ensure success. The projected timescale for significant shortfalls in world energy supply to become apparent is nearly 30 to 40 yr depending on assumptions. The time to develop fusion from near-term R ampersand D through significant commercial market penetration is at least of the same order, so its development must not be delayed. 6 refs., 2 figs

    Full Text Available Based upon a review of corporate performance, corporate financial performance and corporate social performance, we propose that the concept of “triple bottom line” (TBL as “sustainable corporate performance” (SCP should consist of three measurement elements, namely: (i financial, (ii social and (iii environmental. TBL as SCP is proposed to be derived from the interface between them. We also propose that the content of each of these measurement elements may vary across contexts and over time. Furthermore, TBL as SCR should be interpreted to be a relative concept that is dynamic and iterative. Continuous monitoring needs to be performed, adapting the content of the measurement elements to changes that evolve across contexts and over time in the marketplace and society. TBL as SCP may be seen as a function of time and context.

    Global climate change linked to the accumulation of greenhouse gases has caused concerns regarding the use of fossil fuels as the major energy source. To mitigate climate change while keeping energy supply sustainable, one solution is to rely on the ability of microorganisms to use renewable resources for biofuel synthesis. In this Review, we discuss how microorganisms can be explored for the production of next-generation biofuels, based on the ability of bacteria and fungi to use lignocellulose; through direct CO2 conversion by microalgae; using lithoautotrophs driven by solar electricity; or through the capacity of microorganisms to use methane generated from landfill. Furthermore, we discuss how to direct these substrates to the biosynthetic pathways of various fuel compounds and how to optimize biofuel production by engineering fuel pathways and central metabolism.

    The keeping of exotic pets is currently under debate and governments of several countries are increasingly exploring the regulation, or even the banning, of exotic pet keeping. Major concerns are issues of public health and safety, animal welfare and biodiversity conservation. The keeping of reptiles and amphibians in captivity encompasses all the potential issues identified with keeping exotic pets, and many of those relating to traditional domestic pets. Within the context of risks posed by pets in general, the authors argue for the responsible and sustainable keeping of reptile and amphibian pets by private persons, based on scientific evidence and on the authors' own expertise (veterinary medicine, captive husbandry, conservation biology). © British Veterinary Association (unless otherwise stated in the text of the article) 2017.

    Recent developments in science must be considered when designing a teacher training course in order to establish connections with the teacher's own field of work. As constructal law and exergy develop, several scientific fields are benefiting from the input of new knowledge. Chemistry teachers in particular can benefit from a greater understanding of constructal law and how exergy works, their society and environment connections and applications, through the Science, Technology, Society and Environment perspective present in the Portuguese National curricula. The input of new knowledge can boost pedagogical innovation and sustainable development. With advances in information technology, it is easier the access recent developments. This paper described the web 2.0 as a great vehicle to all that new knowledge and encouraged modern chemistry teachers to explore new theories and ideas within chemistry, biotechnology, green energy, biomaterials, astrobiology, nuclear power generation or any chemistry related disciplines. 13 refs.

    The increasing food demand as a result of the rising global population has prompted the large-scale use of fertilizers. As a result of resource constraints and low use efficiency of fertilizers, the cost to the farmer is increasing dramatically. Nanotechnology offers great potential to tailor fertilizer production with the desired chemical composition, improve the nutrient use efficiency that may reduce environmental impact, and boost the plant productivity. Furthermore, controlled release and targeted delivery of nanoscale active ingredients can realize the potential of sustainable and precision agriculture. A review of nanotechnology-based smart and precision agriculture is discussed in this paper. Scientific gaps to be overcome and fundamental questions to be answered for safe and effective development and deployment of nanotechnology are addressed.

    2014-11-01

    Full Text Available The island of Barbuda has a relatively unique history, land tenure and geography. Unlike its Caribbean counterparts, the island is not suited to large-scale agriculture due to its arid climate and relatively thin soils. Instead, the enslaved and eventually free people of Barbuda developed a complex herding ecology centered on common land ownership. As a result, carefully designed historic wells are strategically located around the island. With the challenges brought about by climate change, an interdisciplinary, international team led by the Barbuda Research Complex is investigating the state of existing water and food resources and examining how the availability and quality of water resources have influenced local cultural practices. Barbudans and international scientists are working together to improve their resilience and live more sustainably in this new era of climatic adversity.

    Ecosystems and human communities of the Mississippi delta developed with predictable basin inputs, stable sea level, and as an open system with a high degree of interaction among drainage basin inputs, deltaic plain, and the coastal sea. Human activity changed altered the coast and lowered predictability. Management has become very energy intensive and dependent on cheap resources with more hard engineering and less ecological engineering. Pervasive alteration of the basin and delta and global change have altered the baseline and change is accelerating. Climate change projections include not only sea-level rise, but also more stronger hurricanes, increased large river floods, and more intense rainfall events and droughts. A sustainable Mississippi is outside of the boundaries of the current CMP.

    InTeGrate supports integrated interdisciplinary learning about resource and environmental issues across the undergraduate curriculum to create a sustainable and just civilization. The project has developed teaching materials and examples of their use in programs and is currently engaged in a suite of activities that support use of these resources in improving undergraduate Earth education. Thirty-three sets of teaching materials supporting instruction over time periods of 2 weeks to a full semester have been developed by teams of faculty and peer-reviewed to ensure strong research-based pedagogic design and attention to five design principles: 1) address one or more grand challenges involving the Earth and society, 2) develop student ability to address interdisciplinary problems, 3) improve student understanding of the nature and methods of science and developing geoscientific habits of mind, 4) make use of authentic and credible science data to learn central concepts in the context of scientific methods of inquiry, and, 5) incorporate systems thinking. They have been tested in a wide variety of institutional and disciplinary settings and are documented with instructor notes describing adaptation for specific settings. All published materials passed a review for scientific accuracy. Sixteen program models demonstrate strategies for strengthening learning about Earth and sustainability at scales ranging from a department to an interinstitutional collaboration. These examples document the use of InTeGrate resources in the development and evaluation of these programs. A synthesis of lessons learned by these projects addresses strategies for teaching about the Earth across the curriculum. InTeGrate is currently supporting use of ideas and resources developed over the past six years of project work through a webinar series, workshops at professional society meetings, a traveling workshop program for departments and regions, a set of online learning communities and

    BioScene (scenarios for reconciling biodiversity conservation with declining agriculture use in mountain areas in Europe) was a three-year project (2002 2005) funded by the European Union’s Fifth Framework Programme, and aimed to investigate the implications of agricultural restructuring and decline for biodiversity conservation in the mountain areas of Europe. The research took a case study approach to the analysis of the biodiversity processes and outcomes of different scenarios of agri-environmental change in six countries (France, Greece, Norway, Slovakia, Switzerland, and the United Kingdom) covering the major biogeographical regions of Europe. The project was coordinated by Imperial College London, and each study area had a multidisciplinary team including ecologists and social and economic experts, which sought a comprehensive understanding of the drivers for change and their implications for sustainability. A key component was the sustainability assessment (SA) of the alternative scenarios. This article discusses the development and application of the SA methodology developed for BioScene. While the methodology was objectives-led, it was also strongly grounded in baseline ecological and socio-economic data. This article also describes the engagement of stakeholder panels in each study area and the use of causal chain analysis for understanding the likely implications for land use and biodiversity of strategic drivers of change under alternative scenarios for agriculture and rural policy and for biodiversity management. Finally, this article draws conclusions for the application of SA more widely, its use with scenarios, and the benefits of stakeholder engagement in the SA process.

  7. Integrating Materials, Manufacturing, Design and Validation for Sustainability in Future Transport Systems

    The predictive methods currently used for material specification, component design and the development of manufacturing processes, need to evolve beyond the current `metal centric' state of the art, if advanced composites are to realise their potential in delivering sustainable transport solutions. There are however, significant technical challenges associated with this process. Deteriorating environmental, political, economic and social conditions across the globe have resulted in unprecedented pressures to improve the operational efficiency of the manufacturing sector generally and to change perceptions regarding the environmental credentials of transport systems in particular. There is a need to apply new technologies and develop new capabilities to ensure commercial sustainability in the face of twenty first century economic and climatic conditions as well as transport market demands. A major technology gap exists between design, analysis and manufacturing processes in both the OEMs, and the smaller companies that make up the SME based supply chain.

    The predictive methods currently used for material specification, component design and the development of manufacturing processes, need to evolve beyond the current 'metal centric' state of the art, if advanced composites are to realise their potential in delivering sustainable transport solutions. There are however, significant technical challenges associated with this process. Deteriorating environmental, political, economic and social conditions across the globe have resulted in unprecedented pressures to improve the operational efficiency of the manufacturing sector generally and to change perceptions regarding the environmental credentials of transport systems in particular. There is a need to apply new technologies and develop new capabilities to ensure commercial sustainability in the face of twenty first century economic and climatic conditions as well as transport market demands. A major technology gap exists between design, analysis and manufacturing processes in both the OEMs, and the smaller companies that make up the SME based supply chain. As regulatory requirements align with environmental needs, manufacturers are increasingly responsible for the broader lifecycle aspects of vehicle performance. These include not only manufacture and supply but disposal and re-use or re-cycling.

    Petroleum has been important in the energy industry since 19th century when the refining of paraffin from crude oil began. The industry recently appears to be in a downtown and fragile moment despite the price of oil is slowly rising. Renewable alternatives such as biofuels have gained increasing traction while petroleum fuel seemingly concedes to bio-fuels due to the rising public concern on the environment and stricter emission regulations. To be a strategic fuel in the energy security matrix, both fossil and bio-fuels options should be considered. However, the use of bio-fuels to achieve a degree of carbon neutrality is not without challenges. Among the challenges are land development and socio-political issue, carbon neutrality due to ILUC, high 2G bio-fuel feedstock and production cost, competing technology from electric vehicles and the impending fourth industrial revolution, NOx emissions and variation in biodiesel quality. This paper briefly reviews the potential of fuels source diversification and the challenges and how they can raise up to the challenges in order to be sustainable and attractive. In order to achieve this objective, first carbon credit through carbon trading needs to continue to stabilize the energy price. Second, 1G bio-fuel needs to forgo the use of natural, peat forest, rubber estate since these are an effective carbon sink and oxygen source. Third, advanced bio-fuels with high yield, process economics and sustainability need to be innovated. Fourth, the quality and standard bio-fuel that reduces NOx emission need to be improved. Finally and most importantly, carbon capture technology needs to be deployed immediately in fossil fuel power plants.

  10. Range of Variability in Southern Coastal Plain Forests: Its Historical, Contemporary, and Future Role in Sustaining Biodiversity

    Full Text Available Historical range of variation (HRV has been used as a conceptual tool to determine appropriate management actions to sustain or restore diversity of ecological systems. This concept has come into question for both biological and social considerations, and the southeastern United States is a good model system to test its utility. Southeastern Coastal Plain upland pine savannas and woodlands and their associated wetlands are among the most diverse communities in temperate North America, having both high levels of species richness and large numbers of endemic flora and fauna. However, this diversity is intimately linked with disturbance regimes. Maintaining frequent fire, varied in season based on changing management objectives through time, is the most important management tool for sustaining biodiversity. Moreover, the landscape has been molded by a long history of intense land use that has altered both the biological and the social landscape in which management occurs, and threatens the native diversity. Management must anticipate likely trends and adopt strategies that provide flexibility for managers to deal with the future, both socially and ecologically. In the Southeast, the most dominant trend is associated with urbanization and forest fragmentation, which results from urban sprawl. This issue joins others - fire and smoke, logging, access, in-holdings, and the uncertainty of scientific models, for example - as matters of major concern to the public. Ultimately, it is the public that eventually grants or withholds social permission to manage. We explore, here, the potential and the limitations for how history can inform future management. Rather than being used as a specific management tool, we find that one purpose for which HRV may be well suited is serving as a broad communication framework to help diverse publics understand the concept of landscape dynamics. This approach would provide the fundamental background material for

  11. Mapping future changes in livelihood security and environmental sustainability based on perceptions of small farmers in the Brazilian Amazon

    Full Text Available Deforestation is a widely recognized problem in the Brazilian Amazon. Small farmers play a key role in this process in that they earn their livelihood by ranching and farming. Many studies have addressed the link between deforestation and livelihood strategies adopted by small farmers. Most have focused on advanced monitoring systems, simulation models, and GIS approaches to analyze the interaction of both dimensions, i.e., livelihoods and forest cover change. Although the current toolbox of methods has proved successful in increasing our understanding of these interactions, the models and approaches employed do not consider small farmers' perspectives. On the assumption that local small farmers are agents of land-cover change, understanding how they perceive their own situation is essential to elucidate their actions. Our objective is to explore future changes in livelihood security and environmental sustainability as envisaged by local small farmers in the Brazilian Amazon. Previous livelihood cluster analysis of small farmers located in southeast Pará was integrated with fuzzy cognitive mapping to determine present perceptions and to explore future changes, using global scenarios downscaled to the local situation. Overall, system description differs only on details; all results indicate a strong trade-off between livelihood security and environmental sustainability in all livelihood systems, as identified by the small farmers. However, fundamentally different outcomes are obtained from the future analysis, depending on the livelihood strategy cluster. Achieving win-win outcomes does not necessarily imply a positive scenario, especially if small farmers are dependent on income transfers from the government to provide their livelihood.

    An undersupply of generalists doctors in rural communities globally led to widening participation (WP) initiatives to increase the proportion of rural origin medical students. In 2002 the Australian Government mandated that 25% of commencing Australian medical students be of rural origin. Meeting this target has largely been achieved through reduced standards of entry for rural relative to urban applicants. This initiative is based on the assumption that rural origin students will succeed during training, and return to practice in rural locations. One aim of this study was to determine the relationships between student geographical origin (rural or urban), selection scores, and future practice intentions of medical students at course entry and course exit. Two multicentre databases containing selection and future practice preferences (location and specialisation) were combined (5862), representing 54% of undergraduate medical students commencing from 2006 to 2013 across nine Australian medical schools. A second aim was to determine course performance of rural origin students selected on lower scores than their urban peers. Selection and course performance data for rural (461) and urban (1431) origin students commencing 2006-2014 from one medical school was used. For Aim 1, a third (33.7%) of rural origin students indicated a preference for future rural practice at course exit, and even fewer (6.7%) urban origin students made this preference. Results from logistic regression analyses showed significant independent predictors were rural origin (OR 4.0), lower Australian Tertiary Admissions Rank (ATAR) (OR 2.1), or lower Undergraduate Medical and Health Sciences Admissions Test Section 3 (non-verbal reasoning) (OR 1.3). Less than a fifth (17.6%) of rural origin students indicated a preference for future generalist practice at course exit. Significant predictors were female gender (OR 1.7) or lower ATAR (OR 1.2), but not rural origin. Fewer (10.5%) urban origin

    With a growing population and energy demand in the world, there is a pressing need for research to create secure and accessible energy options with greatly reduced emissions of greenhouse gases. While we work to deploy the clean and efficient technologies that we already have--which will be urgent for the coming decades--we must also work to develop the science for the technologies of the future. This brochure gives examples of some of the most promising developments, and it provides 'snapshots' of cutting edge work of scientists in the field. The areas of greatest promise include biochemistry, nanotechnology, supraconductivity, electrophysics and computing. There are many others.

    Post-error slowing (PES) is consistently observed in decision-making tasks after negative feedback. Yet, findings are inconclusive as to whether PES supports performance accuracy. We addressed the role of PES by employing drift diffusion modeling which enabled us to investigate latent processes of reaction times and accuracy on a large-scale dataset (>5,800 participants) of a visual search experiment with emotional face stimuli. In our experiment, post-error trials were characterized by both adaptive and non-adaptive decision processes. An adaptive increase in participants’ response threshold was sustained over several trials post-error. Contrarily, an initial decrease in evidence accumulation rate, followed by an increase on the subsequent trials, indicates a momentary distraction of task-relevant attention and resulted in an initial accuracy drop. Higher values of decision threshold and evidence accumulation on the post-error trial were associated with higher accuracy on subsequent trials which further gives credence to these parameters’ role in post-error adaptation. Finally, the evidence accumulation rate post-error decreased when the error trial presented angry faces, a finding suggesting that the post-error decision can be influenced by the error context. In conclusion, we demonstrate that error-related response adaptations are multi-component processes that change dynamically over several trials post-error. PMID:28706497

    Full Text Available Soil treatment and improvement is commonly performed in the field of geotechnical engineering. Methods and materials to achieve this such as soil stabilization and mixing with cementitious binders have been utilized in engineered soil applications since the beginning of human civilization. Demand for environment-friendly and sustainable alternatives is currently rising. Since cement, the most commonly applied and effective soil treatment material, is responsible for heavy greenhouse gas emissions, alternatives such as geosynthetics, chemical polymers, geopolymers, microbial induction, and biopolymers are being actively studied. This study provides an overall review of the recent applications of biopolymers in geotechnical engineering. Biopolymers are microbially induced polymers that are high-tensile, innocuous, and eco-friendly. Soil–biopolymer interactions and related soil strengthening mechanisms are discussed in the context of recent experimental and microscopic studies. In addition, the economic feasibility of biopolymer implementation in the field is analyzed in comparison to ordinary cement, from environmental perspectives. Findings from this study demonstrate that biopolymers have strong potential to replace cement as a soil treatment material within the context of environment-friendly construction and development. Moreover, continuing research is suggested to ensure performance in terms of practical implementation, reliability, and durability of in situ biopolymer applications for geotechnical engineering purposes.

  17. From Environmental Connectedness to Sustainable Futures: Topophilia and Human Affiliation with Nature

    2015-07-01

    Full Text Available Human affiliation with nonhuman nature is an important dimension of environmental concern and support for pro-environmental attitudes. A significant theory of human connectedness with nature, the Biophilia Hypothesis, suggests that there exists a genetically based inclination for human affiliation with the biological world. Both support and challenge to the Biophilia Hypothesis are abundant in the literature of environmental psychology. One response that both challenges and builds upon the Biophilia Hypothesis is the Topophilia Hypothesis. The Topophilia Hypothesis has extended the ideas of biophilia to incorporate a broader conception of nonhuman nature and a co-evolutionary theory of genetic response and cultural learning. While the Topophilia Hypothesis is a new idea, it is built upon long-standing scholarship from humanistic geography and theories in human evolution. The Topophilia Hypothesis expands previous theory and provides a multidisciplinary consideration of how biological selection and cultural learning may have interacted during human evolution to promote adaptive mechanisms for human affiliation with nonhuman nature via specific place attachment. Support for this possible co-evolutionary foundation for place-based human affiliation with nonhuman nature is explored from multiple vantage points. We raise the question of whether this affiliation may have implications for multifunctional landscape management. Ultimately, we propose that nurturing potential topophilic tendencies may be a useful method to promote sustainable efforts at the local level with implications for the global.

    Full Text Available Social facilities and services are today more and more organized as modern service companies.They are increasingly working with market mechanisms rules. The evaluation of performance and efficiencycontrols the redistribution of funds to social security systems. The Nobel Prize Winner Muhammad Yunuswas awarded for giving microcredits that helped citizens of his country, to find a way out of poverty.Sustainability is a key topic to the world economy debate. Companies should not pursue the goal of profitmaximization, but they should solve the social problems of the world through their economic actions.Currently 20 percent of the people in the world possess 83 percent of wealth, about 1.73 billion people livebelow the poverty limit. In this review I present the concept of „Social Economy“, underlying the way how tooptimize the actions of social services providers to the needs of the citizens.

    Full Text Available Romanian Wild Carpathia constitutes the ultimate pristine wilderness of the old European continent. Carpathian Mountains landscape experiences and outdoor recreation represents quite unique cultural ecosystem services. The new annotations to the Forest Law are restricting any public access in the woods without authorities’ pre-approval for organised sport, leisure and tourism activities. However, off road vehicle (ORV recreation is a popular activity and a growing transparency concern of National Forest Administration Authorities that is not managed accordingly. Here we show that our ORV recreation frame model can securely allow public access and protect all Romanian mountains. Our results demonstrate how growing ORV recreation popularity can be used in an honest and open way if it is well organized and controlled. We anticipate our assay to be a starting point for a regional and national forest administration sustainable development plan. Furthermore, stopping illegal forest activities is a major target of the anti-logging movement. A well-defined assay for the ORV recreation frame model will be relevant for such developments.

    In many educational contexts throughout the world, increasing focus has been placed on socio-scientific issues; that is, disagreements about potential personal, social and/or environmental problems associated with fields of science and technology. Some suggest (as do we) that many of these potential problems, such as those associated with climate change, are so serious that education needs to be oriented towards encouraging and enabling students to become citizen activists, ready and willing to take personal and social actions to reduce risks associated with the issues. Towards this outcome, teachers we studied encouraged and enabled students to direct open-ended primary (e.g., correlational studies), as well as secondary (e.g., internet searches), research as sources of motivation and direction for their activist projects. In this paper, we concluded, based on constant comparative analyses of qualitative data, that school students' tendencies towards socio-political activism appeared to depend on myriad, possibly interacting, factors. We focused, though, on curriculum policy statements, school culture, teacher characteristics and student-generated research findings. Our conclusions may be useful to those promoting education for sustainability, generally, and, more specifically, to those encouraging activism on such issues informed by student-led research.

    The complexity facing today's energy planners and decision-makers, particularly in the electricity sector, has increased. They must take into account many elements in selecting technologies and strategies that will impact near term energy development and applications in their countries. While costs remain a key factor, tradeoffs between the demands of environmental protection and economic development will have to be made. This fact, together with the needs of many countries to define their energy and electricity programmes in a sustainable manner, has resulted in a growing interest in the application of improved data, tools and techniques for comparative assessment of different electricity generation options, particularly from an environmental and human health viewpoint. Although global emissions of greenhouse gases and other pollutants, e.g. SO 2 , NO x and particulate, must be reduced, the reality today is that these emissions are increasing and are expected to continue to increase. In examining the air pollutants, as well as water effluents and solid waste generated by electricity production, it is necessary to assess the full energy chain from fuel extraction to waste disposal, including the production of construction and auxiliary materials. The paper describes this concept and illustrates its implementation for assessing and comparing electricity generation costs, emissions, wastes and other environmental burdens from different energy sources.

    Through the last decades, environmentally and health-friendly production methods and conscientious use of resources have become crucial for reaching the goal of a more sustainable plant production. Protection of the environment requires careful consumption of limited resources and reduction of chemicals applied during production of ornamental plants. Numerous chemicals used in modern plant production have negative impacts on human health and are hazardous to the environment. In Europe, several compounds have lost their approval and further legal restrictions can be expected. This review presents the more recent progress of genetic engineering in ornamental breeding, delivers an overview of the biological background of the used technologies and critically evaluates the usefulness of the strategies to obtain improved ornamental plants. First, genetic engineering is addressed as alternative to growth retardants, comprising recombinant DNA approaches targeting relevant hormone pathways, e.g. the gibberellic acid (GA) pathway. A reduced content of active GAs causes compact growth and can be facilitated by either decreased anabolism, increased catabolism or altered perception. Moreover, compactness can be accomplished by using a natural transformation approach without recombinant DNA technology. Secondly, metabolic engineering approaches targeting elements of the ethylene signal transduction pathway are summarized as a possible alternative to avoid the use of chemical ethylene inhibitors. In conclusion, molecular breeding approaches are dealt with in a way allowing a critical biological assessment and enabling the scientific community and public to put genetic engineering of ornamental plants into a perspective regarding their usefulness in plant breeding.

    Capacity utilization (CU) measurement is an important task in a manufacturing system, especially in make-to-order (MTO) type manufacturing system with product customization, in predicting capacity to meet future demand. A stochastic discrete-event simulation is developed using ARENA software to determine CU and capacity gap (CG) in short run production function. This study focused on machinery breakdown and product defective rate as random variables in the simulation. The study found that the manufacturing system run in 68.01% CU and 31.99% CG. It is revealed that machinery breakdown and product defective rate have a direct relationship with CU. By improving product defective rate into zero defect, manufacturing system can improve CU up to 73.56% and CG decrease to 26.44%. While improving machinery breakdown into zero breakdowns will improve CU up to 93.99% and the CG decrease to 6.01%. This study helps operation level to study CU using “what-if” analysis in order to meet future demand in more practical and easier method by using simulation approach. Further study is recommended by including other random variables that affect CU to make the simulation closer with the real-life situation for a better decision.

    2017-04-01

    Deforestation in Costa Rica has historically varied between the original degradation of primary forest due to land-based industries, followed by secondary regrowth. The regeneration of forests largely came into effect with incentive based programs such as payments for ecosystem services, creation of large protected areas, and a new industry of ecotourism in the country. Given the changes that have occurred within the last 50 years from heavy deforestation pressures to regeneration patterns, and a correlation between deforestation and policy/economic influences, it is important to understand the historical changes that have occurred and how the forests will change in the future, which provides the objective of this study. Future projections are increasingly important given changes in the global socio-political structure, climatic change, and the ever increasing globalization of capitalistic endeavours. The trajectory of the forest in the country can also serve as a way to track both these global pressures on the natural landscape in Costa Rica, and as a proxy for how to manage deforestation in other similar political and geographic areas of the tropics. To determine the historical deforestation trends and link them to the different biogeophysical and socioeconomic variables, forest maps from 1960-2013 were used in the Dinamica Environment for Geoprocessing Objects (Dinamica EGO) to create deforestation models for Costa Rica. Dinamica EGO is a cellular automata model which utilizes Bayesian statistics and expert opinion to replicate both patterns and quantities of land cover change over time with both static and dynamic variables. Additional legislative variables can be used to track how political pressures shift deforestation both spatially and temporally. The historical model was built and analyzed for changes in landscape metrics such as patch size and distance between 1960 and 2013. After validation of the model's ability to replicate patterns, first between 2005

    For the past few decades, palm oil has gone through a revolution that few would have predicted. From a humble source of edible oil that was heavily criticized as being un-healthy and un-fit for human consumption, it has proven itself based on scientific findings that it is indeed one of the most nutritious edible oils in the world. Besides, palm oil, the cheapest vegetable oil in the market has diversified as one of the main feedstock for oleo-chemical industries. Recently, with the price of crude petroleum hitting records height every other day, palm oil has become one of the few feasible sources for biodiesel, a renewable substitute for petroleum-derived diesel. Nevertheless, the conversion of palm oil into biodiesel has again received criticism from various NGOs worldwide, mainly on extinction of orang utans, deforestation and particularly the food versus fuel dispute. It was claimed that the conversion of food crops to fuel would significantly increase the number of undernourished people in the world. Malaysia, being the world second largest producer of palm oil, is not spared from this criticism. On the contrary, in the present study it was found that palm oil is indeed the most economical and sustainable source of food and biofuel in the world market. Besides, it was shown that it has the capacity to fulfill both demands simultaneously rather than engaging in priority debate. Nevertheless, fuel is now a necessity rather than a luxury for economy and development purposes. A few strategies will then be presented on how palm oil can survive in this feud and emerged as the main supply of affordable and healthy source of edible oil while concurrently satisfying the market demand for biodiesel throughout the world.

    Climate change and global population growth demand creative, multidisciplinary, and multi-benefit approaches for sustaining adequate fresh water resources and protecting ecosystem health. Currently, a driving factor of aquatic ecosystem degradation (stormwater) is also one of the largest untapped urban freshwater resources. This suggests that ecosystem protection and potable water security might both be achieved via treating and capturing stormwater for human use (e.g., potable substitution). The viability of such a scheme, however, depends on 1) initial stormwater quality (e.g., the contaminants present and their associated human/environmental health risks), 2) the spatial and temporal variability of contaminants in stormwater, and 3) the capacity of existing technologies to treat those contaminants to fit for purpose standards. Here we present results from a four year study of urban stormwater conducted across ten catchments and four states in Australia that addresses these three issues relative to stormwater pesticides. In total, 19 pesticides were detected across all sites and times. In general, pesticide concentrations were lower than has been reported in other countries, including the United States, Canada and Europe. This is reflected in few exceedences of public health (< 1%) and aquatic ecosystem standards (0% for invertebrates and fish, < 1% for algae and plants). Interestingly, pesticide patterns were found to be stable across seasons, and years, but varied across catchments. These catchment-specific fingerprints may reflect preferential commercial product use, as they map closely to co-occurrence patterns in registered Australian products. Importantly, the presence of catchment-specific pesticide variability has clear management implications; namely, urban stormwater must be managed at the catchment level and target local contaminant suites in order to best achieve desired human use and environmental protection standards.

    Carbon dioxide is a major raw material of the future, for the capture plants which use amines, aminoacids, ammonia or zeolites. This very high purity raw material (99.9 %) opens the way of a new industrial revolution in agreement with the proposal of Nobel Prize laureates and the DOE strategy. Our goal is to explain the large advantages and the main routes for CO2 valorization, which are starting around the world. The most promising ways for this valorization are methanol synthesis as fuel for transportation and methane formation for electricity network regulation. The first way allows the use of liquid fuels, as distribution infrastructure already exists; instead of gaseous fuels (H2), for which there is storage, distribution problems and no infrastructure exist. The second way is methane synthesis during off-peak hours and burning of this methane during peak hours in order to regulate the electric network.

    Nanocellulose, extracted from the most abundant biomass material cellulose, has proved to be an environmentally friendly material with excellent mechanical performance owing to its unique nano-scaled structure, and has been used in a variety of applications as engineering and functional materials. The great biocompatibility and biodegradability, in particular, render nanocellulose promising in biomedical applications. In this review, the structure, treatment technology and properties of three different nanocellulose categories, i.e., nanofibrillated cellulose (NFC), nanocrystalline cellulose (NCC) and bacterial nanocellulose (BNC), are introduced and compared. The cytotoxicity, biocompatibility and frontier applications in biomedicine of the three nanocellulose categories were the focus and are detailed in each section. Future prospects concerning the cytotoxicity, applications and industrial production of nanocellulose are also discussed in the last section.

    Ports are an important player in the world, due to their role in global production and distributions systems. They are major intermodal transport hubs, linking the sea to the land. For all ports, a key requirement for commercial and economic viability is to retain ships using them and to remain accessible to those ships. Ports need to find approaches to help them remain open. They must ensure their continued economic viability. At the same time, they face increasing pressure to become more environmentally and socially conscious. This paper examines the approach taken by the Port of Gävle, Sweden, which used contaminated dredged materials to create new land using principles of Circular Economy. The paper demonstrates that using Circular Economy principles can be a viable way of securing a port's future and contributing to its sustainability, and that of the city/region where it operates.

    Cord blood is an important source of stem cells. However, nearly 90% of public cord blood banks have declared that they are struggling to maintain their financial sustainability and avoid bankruptcy. The objective of this study is to evaluate how characteristics of cord blood units influence their utilization, then use this information to model the economic viability and therapeutic value of different banking strategies. Retrospective analysis of cord blood data registered between January 1st, 2009 and December 31st, 2011 in Bone Marrow Donor Worldwide. Data were collected from four public banks in France, Germany and the USA. Samples were eligible for inclusion in the analysis if data on cord blood and maternal HLA typing and biological characteristics after processing were available (total nucleated and CD34+ cell counts). 9,396 banked cord blood units were analyzed, of which 5,815 were Caucasian in origin. A multivariate logistic regression model assessed the influence of three parameters on the CBU utilization rate: ethnic background, total nucleated and CD34+ cell counts. From this model, we elaborated a Utilization Score reflecting the probability of transplantation for each cord blood unit. We stratified three Utilization Score thresholds representing four different banking strategies, from the least selective (scenario A) to the most selective (scenario D). We measured the cost-effectiveness ratio for each strategy by comparing performance in terms of number of transplanted cord blood units and level of financial deficit. When comparing inputs and outputs over three years, Scenario A represented the most extreme case as it delivered the highest therapeutic value for patients (284 CBUs transplanted) along with the highest financial deficit (USD 5.89 million). We found that scenario C resulted in 219 CBUs transplanted with a limited deficit (USD 0.98 million) that charities and public health could realistically finance over the long term. We also found that

    After an introduction which outlines the readiness of the third generation of nuclear reactors (the EPR, European Pressurized Reactor, with its remaining fuel recycling problems), the interest of the fourth generation to come (a maximum exploitation of fuel potentialities, a solution of the waste issue), and the importance of international collaboration in researches, this publication highlights the key international strategic role held by France in the revival of nuclear energy. It also highlights the role of nuclear energy in the future energy mix, and that nuclear energy can be considered as a champion in the protection of the environment (very low CO 2 emissions). Other aspects are discussed such as the availability of resources, the good perspectives of waste management drawn by processes like transmutation, the continuous improvement of safety. Drawbacks of other energy sources are highlighted: biomass will promote non-food cropping systems, coal is very polluting and no capture-sequestration process is available, wind turbines have a too low nominal power, solar equipment is expensive and their fabrication is a polluting activity

    Human activities resulting in greenhouse gas (GHG) emissions have been implicated as the primary factor forcing climate change. This evidence led to a landmark international agreement in Kyoto, (1997) committing the developed countries of the world to reductions in GHG emissions. In Canada, fossil fuel use over the past few centuries has released about 5200 Mt C into the atmosphere. An equivalent amount has probably been added as a result of deforestation and agricultural practice in this country. If we can manage our biosphere better and return even a fraction of the lost biosphere C, we can make a significant contribution to reducing Canada's current annual GHG emission. In the process, plants ( including trees) will trap the sun's energy and build an energy-rich biomass that we can learn to utilize as an energy, chemical and material resource for the future. In doing so, we will relieve the escalating demand for fossil fuels. The BIOCAP Network will be a multidisciplinary group of university, government and industry researchers dedicated to exploring the scientific, technological and policy implications of this 'biosphere option'. Canada's 'biosphere option' for GHG management is both a national opportunity and a global responsibility

    This paper presents a short history of water resources systems analysis from its beginnings in the Harvard Water Program, through its continuing evolution toward a general field of water resources systems science. Current systems analysis practice is widespread and addresses the most challenging water issues of our times, including water scarcity and drought, climate change, providing water for food and energy production, decision making amid competing objectives, and bringing economic incentives to bear on water use. The emergence of public recognition and concern for the state of water resources provides an opportune moment for the field to reorient to meet the complex, interdependent, interdisciplinary, and global nature of today's water challenges. At present, water resources systems analysis is limited by low scientific and academic visibility relative to its influence in practice and bridled by localized findings that are difficult to generalize. The evident success of water resource systems analysis in practice (which is set out in this paper) needs in future to be strengthened by substantiating the field as the science of water resources that seeks to predict the water resources variables and outcomes that are important to governments, industries, and the public the world over. Doing so promotes the scientific credibility of the field, provides understanding of the state of water resources and furnishes the basis for predicting the impacts of our water choices.

    Full Text Available Many aquaculture systems generate high amounts of wastewater containing compounds such as suspended solids, total nitrogen and total phosphorus. Today, aquaculture is imperative because fish demand is increasing. However, the load of waste is directly proportional to the fish production. Therefore, it is necessary to develop more intensive fish culture with efficient systems for wastewater treatment. A number of physical, chemical and biological methods used in conventional wastewater treatment have been applied in aquaculture systems. Constructed wetlands technology is becoming more and more important in recirculating aquaculture systems (RAS because wetlands have proven to be well-established and a cost-effective method for treating wastewater. This review gives an overview about possibilities to avoid the pollution of water resources; it focuses initially on the use of systems combining aquaculture and plants with a historical review of aquaculture and the treatment of its effluents. It discusses the present state, taking into account the load of pollutants in wastewater such as nitrates and phosphates, and finishes with recommendations to prevent or at least reduce the pollution of water resources in the future.

    Full Text Available Solar energy is considered one of the most promising and rapidly growing sectors of the world economy. In line with the international trend of switching to renewable energy sources, particularly solar, and because of the tragic events at the Fukushima nuclear power station, Japan is experiencing a real “solar boom.” However, despite all obvious advantages of using solar power (ensuring national energy security, overcoming concerns about environmental consequences of using fossil energy sources, etc., Japan is facing several problems in its development. The most important one is the fact that technological and social progresses in Japan do not match each other as a result of a unique history of the nation. In order to promote renewable technology, the emphasis should be made on the role of the governmental policy and the effects of built-in tariffs for renewable energy sources. Considering dynamics and character of solar energy development in Japan, new energy strategy, and megasolar plants construction, the conclusion might be drawn that in the nearest future Japan will keep its place among the leaders in this field.

    The G-8 leaders issued a statement expressing their commitment 'to encourage the development of energy markets' and declared that 'the greatest environmental threat of our future prosperity remains climate change and we confirm our determination to address it'. One of the options for tackling the greenhouse gas problem is to encourage substitution of carbon free fuels for conventional fossil fuels. This includes renewable energy sources and nuclear power, which has significant advantages to a society troubled by the prospect of climate change triggered by carbon emissions. Fuel supply to civil nuclear power plants is potentially, indefinitely sustainable. Uranium resources are globally widespread and could last 60 years, longer than the known reserves of oil and gas. Technological options are known for increasing the energy extracted from natural uranium. A recent IEA publication 'Nuclear Power Sustainability: Climate Change, Competition' discusses what would be necessary to make both renewable and nuclear energy sources cost-effective

  5. Analysis of Balancing Requirements in Future Sustainable and Reliable Power Systems

    2011-01-01

    This thesis elaborates on the rules for power balancing, provides a method for quantifying balancing requirements and examines the effect of future changes on balancing. Chapter 2 elaborates on system balancing and the different actors and entities in the electricity delivery system. The necessity and implementation of power balancing are explained. Also different subsequent markets (i.e., day-ahead markets, intraday markets and imbalance settlement systems) and options to trade electricity are discussed. As the research focusses mainly on the Netherlands, properties of the Dutch imbalance settlement system are analyzed. Based on this framework an in-depth analysis of imbalances and calls for balancing capacity with the corresponding prices is given. This shows the incentives to minimize the amount of imbalance in the system and to participate in the imbalance settlement system. Chapter 3 elaborates on the level of aggregation that the entities, involved in the imbalance settlement system, in electricity markets can have. Based on current market rules, incentives to either grow or shrink and by aggregating more or less entities are discussed. The level of aggregation will directly influence the functioning of the imbalance settlement system. It is shown that larger aggregations benefit more from the canceling out of imbalances. The imbalances of the Netherlands and Belgium have been aggregated to illustrate the possible benefits of aggregating multiple national imbalance settlement systems. The increased penetration of renewable generation strongly influences the planning and operation of the power system. As many renewable energy generators have a fluctuating power output, several methods are discussed in chapter 4 that can be used to classify and quantify the balancing requirements to counteract these fluctuations. Chapter 4 discusses the multiple existing classes of balancing capacity and the corresponding methods to quantify their needs. Due to the

    Poor air quality and resulting annual deaths represent significant public health concerns. Recently, rapid delay discounting (the devaluation of future outcomes) of air quality has been considered a potential barrier for engaging in long term, sustainable behaviors that might help to reduce emissions (e.g., reducing private car use, societal support for clean air initiatives). Delay discounting has been shown to be predictive of real world behavior outside of laboratory settings, and therefore may offer an important framework beyond traditional variables thought to measure sustainable behavior such as importance of an environmental issue, or environmental attitudes/values, although more research is needed in this area. We examined relations between discounting of air quality, respiratory health, and monetary gains and losses. We also examined, relations between discounting and self-reported importance of air quality and respiratory health, and nature relatedness. Results showed rapid delay discounting of all outcomes across the time frames assessed, and significant positive correlations between delay discounting of air quality, respiratory health, and monetary outcomes. Steeper discounting of monetary outcomes relative to air quality and respiratory health outcomes was observed in the context of gains; however, no differences in discounting were observed across losses of monetary, air quality, and respiratory health. Replicating the sign effect, monetary outcomes were discounted more steeply than monetary losses. Importance of air quality, respiratory health and nature relatedness were significantly and positively correlated with one another, but not with degree of delay discounting of any outcome, demonstrating the need for more comprehensive measures that predict pro-environmental behaviors that might benefit individuals and public health over time. These results add to our understanding of decision-making, and demonstrate alarming rates of delay discounting of

    In this paper, we report on the adaptation and application of a one-dimensional marsh surface elevation model, the Wetland Accretion Rate Model of Ecosystem Resilience (WARMER), to explore the conditions that lead to sustainable tidal freshwater marshes in the Sacramento–San Joaquin Delta. We defined marsh accretion parameters to encapsulate the range of observed values over historic and modern time-scales based on measurements from four marshes in high and low energy fluvial environments as well as possible future trends in sediment supply and mean sea level. A sensitivity analysis of 450 simulations was conducted encompassing a range of eScholarship provides open access, scholarly publishing services to the University of California and delivers a dynamic research platform to scholars worldwide. porosity values, initial elevations, organic and inorganic matter accumulation rates, and sea-level rise rates. For the range of inputs considered, the magnitude of SLR over the next century was the primary driver of marsh surface elevation change. Sediment supply was the secondary control. More than 84% of the scenarios resulted in sustainable marshes with 88 cm of SLR by 2100, but only 32% and 11% of the scenarios resulted in surviving marshes when SLR was increased to 133 cm and 179 cm, respectively. Marshes situated in high-energy zones were marginally more resilient than those in low-energy zones because of their higher inorganic sediment supply. Overall, the results from this modeling exercise suggest that marshes at the upstream reaches of the Delta—where SLR may be attenuated—and high energy marshes along major channels with high inorganic sediment accumulation rates will be more resilient to global SLR in excess of 88 cm over the next century than their downstream and low-energy counterparts. However, considerable uncertainties exist in the projected rates of sea-level rise and sediment avail-ability. In addition, more research is needed to constrain future

    The hyper-arid conditions prevailing in Agua Verde aquifer in northern Chile make this system the most important water source for nearby towns and mining industries. Due to the growing demand for water in this region, recharge is investigated along with the impact of intense pumping activity in this aquifer. A conceptual model of the hydrogeological system is developed and implemented into a two-dimensional groundwater-flow numerical model. To assess the impact of climate change and groundwater extraction, several scenarios are simulated considering variations in both aquifer recharge and withdrawals. The estimated average groundwater lateral recharge from Precordillera (pre-mountain range) is about 4,482 m3/day. The scenarios that consider an increase of water withdrawal show a non-sustainable groundwater consumption leading to an over-exploitation of the resource, because the outflows surpasses inflows, causing storage depletion. The greater the depletion, the larger the impact of recharge reduction caused by the considered future climate change. This result indicates that the combined effects of such factors may have a severe impact on groundwater availability as found in other groundwater-dependent regions located in arid environments. Furthermore, the scenarios that consider a reduction of the extraction flow rate show that it may be possible to partially alleviate the damage already caused to the aquifer by the continuous extractions since 1974, and it can partially counteract climate change impacts on future groundwater availability caused by a decrease in precipitation (and so in recharge), if the desalination plant in Taltal increases its capacity.

    2017-12-01

    Over decades, assessment by the Intergovernmental Panel on Climate Change and many others has bolstered understanding of the climate problem: unequivocal warming, pervasive impacts, and serious risks from continued high emissions of heat-trapping gases. Societies are increasingly responding with early actions to decarbonize energy systems and prepare for impacts. This emerging era of climate solutions creates a need for new approaches to assessment that emphasize learning from ongoing real-world experiences and that help close the gap between aspirations and the pace of progress. Against this backdrop, the presentation will take stock of recent advances and challenges in assessment, especially drawing from analysis of climate change assessment. Four assessment priorities will be considered: (1) integrating diverse evidence including quantitative and qualitative results, (2) applying rigorous expert judgment in evaluating knowledge and uncertainties, (3) exploring widely ranging futures and their connections to ongoing choices and actions, and (4) incorporating interactions among experts and decision-makers in assessment processes. Across these assessment priorities, the presentation will critique both opportunities and pitfalls, outlining possibilities for future experimentation, innovation, and learning. It will evaluate, in particular, lessons from risk-based approaches; strategies for transparently acknowledging persistent uncertainties and contested priorities; ways to minimize biases and foster creativity in expert judgments; scenario-based assessment of surprises, deep uncertainties, and decision-making implications; and opportunities for broadening the conception of expertise and engaging different decision-makers and stakeholders. Overall, these approaches can advance assessment products and processes as a basis for sustained dialogue supporting decision-making.

    Since 2010, Male and female Kenyan life expectancy has gone up from 55 to 57 and 56 to 59 respectively (A United Nations Population Fund report released Wednesday ( 27th Nov 2011). In Kenya, for example CT scanners have increased by over 80% in the last decade resulting in over seventy facilities. Although the benefit from a radiological procedure to the patient outweighs the potential radiation risk, the total number of patients was large and increasing. Therefore, small individual radiation risk, multiplied by the large number of patient, adds up resulting in a major public health problem that may not become clearly evident for many years under inadequate quality assurance program. Most examinations are relatively infrequent, contributing less than 5% each to the total number of x-ray examinations in Kenya. The procedures are arranged in descending order of their collective dose. In setting optimization strategy for a country, it is important that the choice of examinations be based on collective dose contribution and the frequency of the examination to maximize the overall benefit to a given population. According to Grid Radiography - Optimization of patient protection in Kenya is possible. Capacity building and developing technical capabilities in quality assurance (QA) & control (QC) is required.

    Directory of Open Access Journals (Sweden)

    Mona Treude

    2017-06-01

    Full Text Available The future belongs to the youth, but do they really have a say in it? Learning processes with regard to a successful socio-ecological change must start in childhood and adolescence in order to succeed in social transformation. The youth cannot be a passive part in a changing society—they have to be actively included in its design. When allowed to participate, young people can make important and effective contributions—which should not be reduced to sub-projects and opportunity structures. In a socio-political context, participation means involvement, collaboration, and commitment. In the context of intra- and inter-generational equity, as the core part of sustainable development, participation strategies should be developed that allow for a permanent and purposeful involvement of children and adolescents. Participation of young people is an important and appropriate step in strengthening those who are so strongly affected by the planning processes but are otherwise powerless. A successful involvement and participation of non-professional actors requires a target group-oriented method, a supportive culture of participation, as well as clarity and decision latitude. Abiding by these rules leads to central results.

    2005-09-01

    Greenpeace and the Institute of Technical Thermodynamics, Department of Systems Analysis and Technology Assessment of the German Aerospace Center (DLR),have developed a blueprint for the EU energy supply that shows how Europe can lead the way to a sustainable pathway to a clean energy future. The Greenpeace energy revolution scenario demonstrates that phasing out nuclear power and massively reducing CO2-emissions is possible. The scenario comes close to a fossil fuels phase-out by aiming for a 80% CO2 emissions reduction by 2050.The pathway in this scenario achieves this phase-out in a relatively short time-frame without using technological options (such as 'clean coal') that are ultimately dead ends, deflecting resources from the real solutions offered by renewable energy. Whilst there are many technical options that will allow us to meet short-term EU Kyoto targets (-8% GHG by 2010), these may have limited long-term potential. The Greenpeace Energy Revolution Scenario shows that in the long run, renewable energy will be cheaper than conventional energy sources and reduce EU's dependence from world market prices from imported fossil and nuclear fuels.The rapid growth of renewable energy technologies will lead to a large investment in new technologies.This dynamic market growth will result in a shift of employment opportunities from conventional energy-related industries to new occupational fields in the renewable energy industry. Renewable energy is expected to provide about 700,000 jobs in the field of electricity generation from renewable energy sources by 2010

The results reveal that the major differences be- tween the assessed strategies are present in the sophistication of the theoretical bases and the integration of three main pillars of sustainable development (i.e. environmental, economic and social. In general, the assessed strategies re- flect a high degree of inclusiveness of a variety of interests. However, there is a common weak- ness among them in terms of implementation, be it in the provision of adequate resources, the guarantee of adequate implementing capacity of the institutions designated for implementation or the precise definition of the institutional frame- work responsible for the implementation of the strategy.

    Simple Summary To better address consumer concerns, the beef sector is working on strategies to enhance the sustainability of all aspects of the beef supply chain. Among these strategies are (1) the development of science-based frameworks and indicators capable of measuring progress at all stages of beef production; (2) the engagement of different stakeholders along the beef supply chain at regional and global levels; and (3) the improvement of communication among stakeholders and transparency towards consumers. Progress on these three fronts was presented during the 2nd Global Conference on Sustainable Beef, hosted by the Global and Canadian Roundtables for Sustainable Beef. During the event, there was a clear understanding that the beef industry is substantially advancing efforts to continuously improve its sustainability, both at regional and global levels, by developing assessment frameworks and indicators to measure progress. However, it is also clear that the beef sector has a need to more clearly define the concept of beef sustainability, strengthen cooperation and exchange of information among national roundtables for sustainable beef, as well as improve the flow of information along the supply chain. An improved transparency in the beef sector will help consumers make more informed decisions about food products. Abstract The beef sector is working towards continually improving its sustainability in order to achieve environmentally, socially and economically desirable outcomes, all of which are of increasing concern to consumers. In this context, the Global Roundtable for Sustainable Beef (GRSB) provides guidance to advance the sustainability of the beef industry, through increased stakeholder engagement and the formation of national roundtables. Recently, the 2nd Global Conference on Sustainable Beef took place in Banff, Alberta, Canada, hosted by the GRSB and the Canadian Roundtable for Sustainable Beef. Conference attendees discussed the various

    Water-human systems are coupled and display co-evolutionary dynamics influenced by society's values and preference. This has been observed in the Murrumbidgee basin, Australia where water usage initially focused on agriculture production and until mid-1990's favoured agriculture. This turned around as society became more concerned about the degradation of ecosystems and ultimately water was reallocated back towards the environment. This new water management adversely impacted the agriculture sector and created economic stress in the basin. The basin communities were able to transform and cope with water allocation favouring the environment through sectoral transformation facilitated by movement of capital in a free economy, supported by appropriate strategies and funding. This was helped by the adaptive capacity of people through reemployment in other economic sectors of the basin economy, unemployment for a period of time and migration out of the basin, and crop diversification. This study looks to the future and focuses on how water managers could be informed and prepare for un-foreseen issues coming out of societies changing values and preferences and emerging as different systems in the basin interact with each other at different times and speed. The issues of this type that concern the Murray Darling Basin Authority include a renewed focus and priority on food production due to food scarcity; increased impact and frequency of natural disasters (eg. climate change); regional economic diversification due to the growth of peri-urban development in the basin; institutional capacity for water reform due to new political paradigms (eg. new water sharing plans); and improvement in science and technology (eg. farm practices, water efficiency, water reuse). To undertake this, the study uses a coupled socio-hydrological dynamical system that model the major drivers of changing economic conditions, society values and preference, climatic condition and science and

    Science and innovation are important components underpinning the agricultural and agri-food system in Canada. Canada's vast geographical area presents diverse, regionally specific requirements in addition to the 21st century agricultural challenges facing the overall sector. As the broader needs of the agricultural landscape have evolved and will continue to do so in the next few decades, there is a trend in place to transition towards a sustainable bioeconomy, contributing to reducing greenhouse gas emission and our dependency on non-renewable resources. We highlight some of the key policy drivers on an overarching national scale and those specific to agricultural research and innovation that are critical to fostering a supportive environment for innovation and a sustainable bioeconomy. As well, we delineate some major challenges and opportunities facing agriculture in Canada, including climate change, sustainable agriculture, clean technologies, and agricultural productivity, and some scientific initiatives currently underway to tackle these challenges. The use of various technologies and scientific efforts, such as Next Generation Sequencing, metagenomics analysis, satellite image analysis and mapping of soil moisture, and value-added bioproduct development will accelerate scientific development and innovation and its contribution to a sustainable and prosperous bioeconomy.

    Technical product harvesting (TEPHA) is a newly developing interdisciplinary approach in which bio-based production is investigated from a technical and ecological perspective. Society's demand for ecologically produced and sustainably operable goods is a key driver for the substitution of conventional materials like metals or plastics through bio-based alternatives. Technical product harvesting of near net shape grown components describes the use of suitable biomass for the production of technical products through influencing the natural shape of plants during their growth period. The use of natural materials may show positive effects on the amount of non-renewable resource consumption. This also increases the product recyclability at the end of its life cycle. Furthermore, through the near net shape growth of biomass, production steps can be reduced. As a consequence such approaches may save energy and the needed resources like crude oil, coal or gas. The derived near net shape grown components are not only considered beneficial from an environmental point of view. They can also have mechanical advantages through an intrinsic topology optimization in contrast to common natural materials, which are influenced in their shape after harvesting. In order to prove these benefits a comprehensive, interdisciplinary scientific strategy is needed. Here, both mechanical investigations and life cycle assessment as a method of environmental evaluation are used.

    For the first time in 2015, aquaculture yields approximately equaled global wild capture fisheries. Are either of these levels of production sustainable? This course explored the limitations of both sources of fishery landings and included legal limitations, environmental concerns and technological problems and adaptations. It made use of visits to aquaculture facilities, government laboratories like NOAA , as well as large fish distribution centers like J.J. McDowell's Seafood (Jessup, MD), and included presentations by experts on legalities including the Law of the Sea. In addition, short day-long trips to "ocean-related" locations were also used to supplement the experience and included speakers involved with aquaculture. Central Virginia is a fortunate location for such a class, with close access for travel to the Chesapeake Bay and numerous field stations, museums with ocean-based exhibits (the Smithsonian and National Zoo) that address both extant and extinct Earth history, as well as national/state aquaria in Baltimore and Virginia Beach. Furthermore, visits to local seafood markets at local grocery stores, or larger city markets in Washington, Baltimore and Virginia Beach, enhance the exposure to productivity in the ocean, and viability of the fisheries sustainability. Sustainability awareness is increasingly a subject in educational settings. Marine science classes are perfect settings of establishing sustainability awareness owing to declining populations of organisms and perceived collapse in fisheries worldwide. Students in oceanography classes often request more direct exposure to actual ocean situations or field trips. This new approach to such a course supplement addresses the requests by utilizing local resources and short field trips for a limited number of students to locations in which Ocean experiences are available, and are often supported through education and outreach components. The vision of the class was a mixture of classroom time

    Strategies for beneficial use of biosolids in New Zealand and elsewhere are currently focused primarily on land application. The long-term success of these and other strategies is dependent not only on technical factors, but also on their environmental, economic, social and cultural sustainability. This paper briefly reviews the situation with respect to biosolids management in New Zealand, where land application is not yet widespread; the rise in public opposition to land application in the United States; and the biosolids industry's approach to public engagement. We argue that, at least until recently, the industry has misinterpreted the nature and meaning of public opposition and thus substituted public relations for public engagement. We argue that genuine public engagement is necessary and that its purpose cannot be to gain public acceptance for an already-decided-upon strategy. It therefore calls for humility among biosolids managers, including a willingness to open up the framing of 'the problem', to acknowledge areas of uncertainty, and to recognise the role of values in 'technical' decision-making. We then present and analyse an example of the use of the scenario workshop process for public participation in biosolids management policy in Christchurch, New Zealand, and conclude that scenario workshops and related methods represent an opportunity to enhance sustainable waste management when certain conditions are met.

    The idea that human well-being (WB) can be supported and even enhanced by using, producing, buying, selling and consuming less `stuff' is anathema to many living under consumer capitalism. Yet a growing research literature actually finds that frequent engagement in pro-ecological behaviours (PEBs) is positively correlated with personal WB. This paper reviews data relevant to three possible explanations for the apparent compatibility of PEBs and WB: (i) engaging in PEBs leads to psychological need satisfaction, which in turn causes WB; (ii) being in a good mood causes people to engage in more prosocial behaviours, including PEBs; and (iii) personal characteristics and lifestyles such as intrinsic values, mindfulness and voluntary simplicity cause both PEBs and WB. Because each explanation has some empirical support, I close by reflecting on some relevant interventions and policies that could strengthen each of these three pathways and thereby promote living both well and sustainably. This article is part of the themed issue 'Material demand reduction'.

    We have built particle accelerators to understand the forces that make up our physical world. Yet, we do not understand the principles underlying our strongly connected, techno-socio-economic systems. We have enabled ubiquitous Internet connectivity and instant, global information access. Yet we do not understand how it impacts our behavior and the evolution of society. To fill the knowledge gaps and keep up with the fast pace at which our world is changing, a Knowledge Accelerator must urgently be created. The financial crisis, international wars, global terror, the spreading of diseases and cyber-crime as well as demographic, technological and environmental change demonstrate that humanity is facing serious challenges. These problems cannot be solved within the traditional paradigms. Moving our attention from a component-oriented view of the world to an interaction-oriented view will allow us to understand the complex systems we have created and the emergent collective phenomena characterising them. This paradigm shift will enable new solutions to long-standing problems, very much as the shift from a geocentric to a heliocentric worldview has facilitated modern physics and the ability to launch satellites. The FuturICT flagship project will develop new science and technology to manage our future in a complex, strongly connected world. For this, it will combine the power of information and communication technology (ICT) with knowledge from the social and complexity sciences. ICT will provide the data to boost the social sciences into a new era. Complexity science will shed new light on the emergent phenomena in socially interactive systems, and the social sciences will provide a better understanding of the opportunities and risks of strongly networked systems, in particular future ICT systems. Hence, the envisaged FuturICT flagship will create new methods and instruments to tackle the challenges of the 21st century. FuturICT could indeed become one of the most

    Sagawa, N.

    1997-01-01

    Many people in the world express the concern that global warming will become an increasingly serious problem. A rapid increase in population and demand for energy in the Asian region must be discussed in this context. Despite the forecast of an increase in demand for energy, the Asian region is short of oil and natural gas resources. In addition, only less energy can be supplied by renewable energy sources in the Asian region than in the other regions because of high population density. Nuclear energy is an important energy resource for fulfilling the future increasing energy demand in the Asian region and for contributing to the suppression of carbon dioxide emissions. In the Asian region alone, however, we cannot rely limitlessly on LWR which does not use plutonium. According to a scenario analysis, the total capacity of nuclear power plants in the Asian region would reach large scale and the cumulative amount of demand for natural uranium will increase to about 5 million tons in the Asian region alone. Just the nuclear power plants of this scale in Asia alone will rapidly consume the world's cheap natural uranium resources if we rely only on natural uranium. In the Asian region, few countries have embarked on nuclear power generation and the capacity of equipment is still small. Currently, however, many plans for nuclear power generation are being designed. Many Asian countries obviously consider nuclear power generation as a valid option. Many potential policies must be examined in the light of future uncertainty. In the future, both renewable energy and nuclear energy must be resorted to. When nuclear energy is utilized, the use of plutonium and FBR in the Asian region must be taken into account in order to attain continual growth and development. (author)

    Land-use and transport policies contribute to worldwide epidemics of injuries and non-communicable diseases through traffic exposure, noise, air pollution, social isolation, low physical activity, and sedentary behaviours. Motorised transport is a major cause of the greenhouse gas emissions that are threatening human health. Urban and transport planning and urban design policies in many cities do not reflect the accumulating evidence that, if policies would take health effects into account, they could benefit a wide range of common health problems. Enhanced research translation to increase the influence of health research on urban and transport planning decisions could address many global health problems. This paper illustrates the potential for such change by presenting conceptual models and case studies of research translation applied to urban and transport planning and urban design. The primary recommendation of this paper is for cities to actively pursue compact and mixed-use urban designs that encourage a transport modal shift away from private motor vehicles towards walking, cycling, and public transport. This Series concludes by urging a systematic approach to city design to enhance health and sustainability through active transport and a move towards new urban mobility. Such an approach promises to be a powerful strategy for improvements in population health on a permanent basis. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Food systems account for 18-20% of UK annual greenhouse gas emissions (GHGEs). Recommendations for improving food choices to reduce GHGEs must be balanced against dietary requirements for health. We assessed whether a reduction in GHGEs can be achieved while meeting dietary requirements for health. A database was created that linked nutrient composition and GHGE data for 82 food groups. Linear programming was used iteratively to produce a diet that met the dietary requirements of an adult woman (19-50 y old) while minimizing GHGEs. Acceptability constraints were added to the model to include foods commonly consumed in the United Kingdom in sensible quantities. A sample menu was created to ensure that the quantities and types of food generated from the model could be combined into a realistic 7-d diet. Reductions in GHGEs of the diets were set against 1990 emission values. The first model, without any acceptability constraints, produced a 90% reduction in GHGEs but included only 7 food items, all in unrealistic quantities. The addition of acceptability constraints gave a more realistic diet with 52 foods but reduced GHGEs by a lesser amount of 36%. This diet included meat products but in smaller amounts than in the current diet. The retail cost of the diet was comparable to the average UK expenditure on food. A sustainable diet that meets dietary requirements for health with lower GHGEs can be achieved without eliminating meat or dairy products or increasing the cost to the consumer.

    The microstructure of inclusions in low carbon free cutting steel without lead addition was investigated using small-angle X-ray scattering (SAXS) coupled with small-angle neutron scattering (SANS). The two-dimensional (2D) SAXS pattern shows clear scattering due to inclusions composed of large elongated particles aligned along the rolling direction, and small isotropic particles. From a comparison of the simulated and experimental 2D SAXS patterns, the shapes of the inclusions are regarded as ellipsoid for the larger inclusions and spherical for the smaller inclusions. The length of the minor axis in the large inclusion is 6.9 μm, while the diameter of the small inclusion is 0.50 μm. The aspect ratio of the large inclusion is estimated to be 3.8 in the lower q region, and is reduced slightly to 3.5 in the higher q region from the azimuthal plots. The results of an alloy contrast variation (ACV) analysis using both the SAXS and SANS data indicate that the chemical composition of the inclusions is almost NaCl-type manganese sulfide, and that the amount of iron sulfide is low. The volume fractions are 1.4% for the large inclusions and 0.2% for the small inclusions. This is consistent with the area fraction estimated using an optical microscope, and indicates that nearly all of the sulfur in the steel sample forms the manganese sulfide inclusions. (author)

    Full Text Available The current materials used in proton exchange membrane fuel cells (PEMFCs are not sufficiently durable for commercial deployment. One of the major challenges lies in the development of an inexpensive, efficient, and highly durable and active electrocatalyst. Here a new type of carbon-free Pt/Nb-TiO2 electrocatalyst has been reported. Mesoporous Nb-TiO2 hollow spheres were synthesized by the sol-gel method using polystyrene (PS sphere templates. Pt nanoparticles (NPs were then deposited onto mesoporous Nb-TiO2 hollow spheres via a simple wet-chemical route in aqueous solution, without the need for surfactants or potentiostats. The growth densities of Pt NPs on Nb-TiO2 supports could be easily modulated by simply adjusting the experimental parameters. Electrochemical studies of Pt/Nb-TiO2 show much enhanced activity and stability than commercial E-TEK Pt/C catalyst. PtNP/Nb-TiO2 is a promising new cathode catalyst for PEMFC applications.

    Over the past 50 years, the National Aeronautics and Space Administration (NASA) has delivered space transportation solutions for America's complex missions, ranging from scientific payloads that expand knowledge, such as the Hubble Space Telescope, to astronauts and lunar rovers destined for voyages to the Moon. Currently, the venerable Space Shuttle, which has been in service since 1981, provides the United States' (U.S.) capability for both crew and heavy cargo to low-Earth orbit to' construct the International Space Station, before the Shuttle is retired in 2010. In the next decade, NASA will replace this system with a duo of launch vehicles: the Ares I Crew Launch Vehicle and the Ares V Cargo Launch Vehicle (Figure 1). The goals for this new system include increased safety and reliability coupled with lower operations costs that promote sustainable space exploration for decades to come. The Ares I will loft the Orion Crew Exploration Vehicle, while the heavy-lift Ares V will carry the Altair Lunar Lander and the equipment and supplies needed to construct a lunar outpost for a new generation of human and robotic space pioneers. This paper will provide details of the in-house systems engineering and vehicle integration work now being performed for the Ares I and planned for the Ares V. It will give an overview of the Ares I system-level test activities, such as the ground vibration testing that will be conducted in the Marshall Center's Dynamic Test Stand to verify the integrated vehicle stack's structural integrity and to validate computer modeling and simulation (Figure 2), as well as the main propulsion test article analysis to be conducted in the Static Test Stand. These activities also will help prove and refine mission concepts of operation, while supporting the spectrum of design and development work being performed by Marshall's Engineering Directorate, ranging from launch vehicles and lunar rovers to scientific spacecraft and associated experiments

  8. Mapping alternative energy paths for taiwan to reach a sustainable future: An application of the leap model

    Chen, Wei-Ming

    Energy is the backbone of modern life which is highly related to national security, economic growth, and environmental protection. For Taiwan, a region having limited conventional energy resources but constructing economies and societies with high energy intensity, energy became the throat of national security and development. This dissertation explores energy solutions for Taiwan by constructing a sustainable and comprehensive energy planning framework (SCENE) and by simulating alternative energy pathways on the horizon to 2030. The Long-range Energy Alternatives Planning system (LEAP) is used as a platform for the energy simulation. The study models three scenarios based on the E4 (energy -- environment -- economic -- equity) perspectives. Three scenarios refer to the business-as-usual scenario (BAU), the government target scenario (GOV), and the renewable and efficiency scenario (REEE). The simulation results indicate that the most promising scenario for Taiwan is the REEE scenario, which aims to save 48.7 million tonnes of oil equivalent (Mtoe) of final energy consumption. It avoids USD 11.1 billion on electricity expenditure in final demand sectors. In addition, the cost of the REEE path is the lowest among all scenarios before 2020 in the electricity generation sector. In terms of global warming potential (GWP), the REEE scenario could reduce 35 percent of the GWP in the demand sectors, the lowest greenhouse gases emission in relation to all other scenarios. Based on lowest energy consumption, competitive cost, and least harm to the environment, the REEE scenario is the best option to achieve intergenerational equity. This dissertation proposes that promoting energy efficiency and utilizing renewable energy is the best strategy for Taiwan. For efficiency improvement, great energy saving potentials do exist in Taiwan so that Taiwan needs more ambitious targets, policies, and implementation mechanisms for energy efficiency enhancement to slow down and decrease

    This work seeks to demonstrate how different types of organic agriculture can meet the need for renewable and sustainable agriculture, rural development, and management of the land and water resources. An obstacle to the spread of organic agriculture is the widespread perception that without intensive factors of production, demographic growth will necessarily outstrip the available food resources. Calculation of economic costs and benefits at present carries greater weight in planning than do soil erosion, deforestation, extinction of species, disappearance of habitats, and similar environmental damage. The different types of organic agriculture do not follow rigid rules and are not defined solely by the nonuse of nitrogenous fertilizers and pesticides. One of the main principles or organic agriculture is to respect local soil and climatic conditions. Self-sufficiency regarding external factors of production and an emphasis on recycling and optimal use of natural resources were concept ahead of their time when they initially were introduced in the 1920s. The specialization which restructured agriculture over the past century has seriously damaged the system of mixed agriculture and the chain of food production. The solution will be to seek for each region an appropriate balance linking animals and agricultural production in an organic process. The objective of organic agriculture, also known as autonomous ecosystem management, is to preserve as far as possible the balance between needs for food and fiber on the 1 hand and the potential of local ecosystems on the other. General principles of organic agriculture include mixed exploitation in which both plants and animals have specific functions in the context of their local soil and climatic characteristics. Different types of crop rotation are practiced to optimize mutual interactions between crops, and the varied organic cycles are also optimized within the framework of anorganic management in accord with nature

    This paper compares battery electric vehicles (BEV) to hydrogen fuel cell electric vehicles (FCEV) and hydrogen fuel cell plug-in hybrid vehicles (FCHEV). Qualitative comparisons of technologies and infrastructural requirements, and quantitative comparisons of the lifecycle cost of the powertrain over 100,000 mile are undertaken, accounting for capital and fuel costs. A common vehicle platform is assumed. The 2030 scenario is discussed and compared to a conventional gasoline-fuelled internal combustion engine (ICE) powertrain. A comprehensive sensitivity analysis shows that in 2030 FCEVs could achieve lifecycle cost parity with conventional gasoline vehicles. However, both the BEV and FCHEV have significantly lower lifecycle costs. In the 2030 scenario, powertrain lifecycle costs of FCEVs range from $7360 to $22,580, whereas those for BEVs range from $6460 to $11,420 and FCHEVs, from $4310 to $12,540. All vehicle platforms exhibit significant cost sensitivity to powertrain capital cost. The BEV and FCHEV are relatively insensitive to electricity costs but the FCHEV and FCV are sensitive to hydrogen cost. The BEV and FCHEV are reasonably similar in lifecycle cost and one may offer an advantage over the other depending on driving patterns. A key conclusion is that the best path for future development of FCEVs is the FCHEV.

    Universal access to health care in most western European countries has been a given for many decades; however, macroeconomic developments and increased pressure on health care budgets could mean the status quo cannot be maintained. As populations age, a declining proportion of economically active citizens are being required to support a larger burden of health and social care, while increasing availability of novel technologies for extending and improving life continues to push health care costs upwards. With health expenditure continuing to rise as a proportion of national income, concerns are raised about the current and future financial sustainability of Organisation for Economic Co-Operation and Development (OECD) health care systems. Against this backdrop, a discussion about options to fund health care in the future, including whether to raise additional health care finance (and the ways to do so), reallocate resources and/or ration services becomes very pertinent. This study elicits preferences among a group of key stakeholders (payers, providers, government, academia and health-related industry) on the issue of health care financial sustainability and the future funding of health care services, with a view to understanding the different degrees of acceptability between policy interventions and future funding options as well as their feasibility. We invited 842 individuals from academia, other research organisations (eg. think tanks), national health services, providers, health insurance organisations, government representatives and health-related industry and related advisory stakeholders to participate in an online survey collecting preferences on a variety of revenue-generating mechanisms and cost/demand reducing policies. Respondents represented the 28 EU member states as well as Norway, Iceland, Switzerland, Australia, Russian Federation, Canada and New Zealand. We received 494 responses to our survey from all stakeholder groups. Across all groups, the

    As the largest energy infrastructure in China, power sector consumed more coal than any other sector and threatened air quality and greenhouse gas (GHG) abatement target. In this work, we assessed the evolution of coal-fired power plants in China during 2010-2030 and the evolution of associated emissions for the same period by using a unit-based emission projection model which integrated the historical power plants information, turnover of the future power plant fleet, and the evolution of end-of-pipe control technologies. We found that, driven by the stringent environmental legislation, SO2, NOx, and PM2.5 emissions from China's coal-fired power plants decreased by 49%, 45%, and 24% respectively during 2010-2015, comparing to 14% increase of coal consumption and 15% increase in CO2 emissions. We estimated that under current national energy development planning, coal consumption and CO2 emissions from coal-fired power plants will continue to increase until 2030, in which against the China's Intended Nationally Determined Contributions (INDCs) targets. Early retirement of old and low-efficient power plants will cumulatively reduce 2.2 Pg CO2 emissions from the baseline scenario during 2016-2030, but still could not curb CO2 emissions from the peak before 2030. Owing to the implementation of "near zero" emission control policy, we projected that emissions of air pollutants will significantly decrease during the same period under all scenarios, indicating the decoupling trends of air pollutants and CO2 emissions. Although with limited direct emission reduction benefits, increasing operating hours of power plants could avoid 236 GW of new power plants construction, which could indirectly reduce emissions embodied in the construction activity. Our results identified a more sustainable pathway for China's coal-fired power plants, which could reduce air pollutant emissions, improve the energy efficiency, and slow down the construction of new units. However, continuous

    During the past 15 yr, the global requirement for fertilizers has grown considerably, mainly due to demand by a larger and wealthier world population for more and higher-quality food. The demand and price for potash as a primary fertilizer ingredient have increased in tandem, because of the necessity to increase the quantity and quality of food production on the decreasing amount of available arable land. The primary sources of potash are evaporates, which occur mainly in marine salt basins and a few brine-bearing continental basins. World potash resources are large, but distribution is inequitable and not presently developed in countries where population and food requirements are large and increasing. There is no known substitute for potash in fertilizer, so knowledge of the world’s potash resources is critical for a sustainable future. The U.S. Geological Survey recently completed a global assessment of evaporite-hosted potash resources, which included a geographic information system–based inventory of known potash resources. This assessment included permissive areas or tracts for undiscovered resources at a scale of 1:1,000,000. Assessments of undiscovered potash resources were conducted for a number of the world’s evaporite-hosted potash basins. The data collected provide a major advance in our knowledge of global potash resources that did not exist prior to this study. The two databases include: (1) potash deposits and occurrences, and (2) potash tracts (basins that contain these deposits and occurrences and potentially undiscovered potash deposits). Data available include geology, mineralogy, grade, tonnage, depth, thickness, areal extent, and structure, as well as numerous pertinent references.

    This paper discusses the contribution of street orientation towards the development of a comfortable microclimate for pedestrians in Bahrain. Increasing walkability is a global agenda to address issues such as a) transportation, b) energy consumption, c) health, and d) air pollution, all of which are topics of the sustainability agenda. Thermal comfort is one of the pre-requisites for walkability. In warm climates, this is a challenging goal. Street design is paramount for pedestrian comfort in warm climates. The roles of street orientation and aspect ratio are of particular importance as they determine the intake of solar radiation into the urban canyon. We investigate the state of affairs in Bahrain, by measuring the frequency with which the street orientations E-W, N-S, NE-SW, and NW-SE, currently occur. Research suggests that the street orientation E-W presents the lesser performance for mitigating the effects of heat gain. The ideal grid orientation would, therefore, be N-S, and NE-SW - NW-SE, avoiding street segments with E-W orientation. A countrywide analysis shows that E-W orientation accounts for the highest overall street length with 37%. The second most frequent orientation is N-S (29%), the best performer. NW-SE and NE-SW both have frequencies of only 17%. Preference for a street grid with N-S, NW-SE, and NE-SW orientation would improve the thermal performance of streets and provide a continuous network of a comfortable pedestrian environment. We simulate two future scenarios based on avoiding new E-W streets, or not. We measure their potential reduction in thermal gain and conclude that a simple policy could reduce solar exposition in 40%.

    2018-02-01

    In this work, the carbon-free Li4Ti5O12 porous nanofibers (Li4Ti5O12-P-NFs) have been successfully fabricated through an electrospinning approach followed by a one-step solid-state reaction. The structural and morphological characterization indicates that the as-prepared Li4Ti5O12-P-NFs has a spinel Li4Ti5O12 phase and many nanosized pores are homogeneously dispersed in the one-dimensional nanofibers. When used as anode material for lithium-ion batteries, the Li4Ti5O12-P-NFs exhibit excellent battery performances in terms of high-rate capability and ultralong-life stability, which can be attributed to the unique carbon-free porous nanostructure composed of well-crystallized Li4Ti5O12 nanocrystals. Thus, we can speculate that this novel concept may also be applicable to prepare other electrode materials for high-performance lithium-ion batteries.

    To provide a review of sustainable sizing practices that reduce waste, increase sales, and simultaneously produce safer, better fitting, accommodating products. Sustainable sizing involves a set of methods good for both the environment (sustainable environment) and business (sustainable business). Sustainable sizing methods reduce (1) materials used, (2) the number of sizes or adjustments, and (3) the amount of product unsold or marked down for sale. This reduces waste and cost. The methods can also increase sales by fitting more people in the target market and produce happier, loyal customers with better fitting products. This is a mini-review of methods that result in more sustainable sizing practices. It also reviews and contrasts current statistical and modeling practices that lead to poor fit and sizing. Fit-mapping and the use of cases are two excellent methods suited for creating sustainable sizing, when real people (vs. virtual people) are used. These methods are described and reviewed. Evidence presented supports the view that virtual fitting with simulated people and products is not yet effective. Fit-mapping and cases with real people and actual products result in good design and products that are fit for person, fit for purpose, with good accommodation and comfortable, optimized sizing. While virtual models have been shown to be ineffective for predicting or representing fit, there is an opportunity to improve them by adding fit-mapping data to the models. This will require saving fit data, product data, anthropometry, and demographics in a standardized manner. For this success to extend to the wider design community, the development of a standardized method of data collection for fit-mapping with a globally shared fit-map database is needed. It will enable the world community to build knowledge of fit and accommodation and generate effective virtual fitting for the future. A standardized method of data collection that tests products' fit methodically

    Ammonia has been suggested as a carbon-free hydrogen source, but a convenient method for producing hydrogen from ammonia with rapid initiation has not been developed. Ideally, this method would require no external energy input. We demonstrate hydrogen production by exposing ammonia and O 2 at room temperature to an acidic RuO 2 /γ-Al 2 O 3 catalyst. Because adsorption of ammonia onto the catalyst is exothermic, the catalyst bed is rapidly heated to the catalytic ammonia autoignition temperature, and subsequent oxidative decomposition of ammonia produces hydrogen. A differential calorimeter combined with a volumetric gas adsorption analyzer revealed a large quantity of heat evolved both with chemisorption of ammonia onto RuO 2 and acidic sites on the γ-Al 2 O 3 and with physisorption of multiple ammonia molecules.

    2018-04-01

    In vertical GaN PN diodes (PNDs) grown entirely by metal–organic chemical vapor deposition (MOCVD), large current nonuniformity was observed. This nonuniformity was induced by macrosteps on the GaN surface through modulation of carbon incorporation into the n-GaN crystal. It was eliminated in a hybrid PND consisting of a carbon-free n-GaN layer grown by hydride vapor phase epitaxy (HVPE) and an MOCVD-regrown p-GaN layer. The hybrid PND showed a fairly low on-resistance (2 mΩ cm2) and high breakdown voltage (2 kV) even without a field plate electrode. These results clearly indicated the strong advantages of the HVPE-grown drift layer for improving power device performance, uniformity, and yield.

    Full Text Available The sustainability becomes a model of development only if countries, industries, businesses and citizens become sustainable. The contribution of the business to a promising future should come from a fully integrated sustainability in its DNA and strategies.This paper focuses on the needed sustainable strategies for scaling up the contribution of the companies to sustainable development in the future. At the beginning, we analyze the main theoretical points of view on sustainability. Then, we explain how companies could achieve the sustainability by following the steps of a difficult process and the present performances in sustainability of large companies around the world. Finally, we suggest four strategies that businesses could design and implement in order to scaling up their sustainability in the future.The research has two important conclusions on sustainability in business. One is that the sustainability pays off if it is integrated in the DNA of the companies. The other conclusion says that the companies will succeed to make the needed transformation for achieving a better sustainability in the future only if they design and perform strategies focused on improving sustainability.

    The Magnéli phase Ti8O15 nanowires (NWs) have been grown directly on a Ti substrate by a facile one-step evaporation-deposition synthesis method under a hydrogen atmosphere. The Ti8O15 NWs exhibit an outstanding electrical conductivity at room temperature. The electrical conductivity of a single Ti8O15 nanowire is 20.6 S cm-1 at 300 K. Theoretical calculations manifest that the existence of a large number of oxygen vacancies changes the band structure, resulting in the reduction of the electronic resistance. The Magnéli phase Ti8O15 nanowires have been used as conductive carbon-free supports to load Pt nanoparticles for direct methanol oxidation reaction (MOR). The Pt/Ti8O15 NWs show an enhanced activity and extremely high durability compared with commercial Pt/C catalysts.The Magnéli phase Ti8O15 nanowires (NWs) have been grown directly on a Ti substrate by a facile one-step evaporation-deposition synthesis method under a hydrogen atmosphere.

    2011-01-01

    Facing climate change and growing energy prices, the use of bioenergy is continuously increasing in order to diminish greenhouse gas emissions, secure energy supply and create employment in rural areas. Because the production of biomass or biofuels, wherever it takes place, comes along with externalities, positive or negative, the need for biomass and bioenergy sustainability criteria is more than ever felt. Research on sustainability criteria and certification systems has started through several national and international initiatives. Considering the benefits of an increased use of bioenergy but also the urge for limiting potential negative environmental and socio-economic impacts, the aim of these initiatives was to make the first move regarding bioenergy sustainability, while waiting for the European legislation to regulate this crucial issue. Land use changes, whether direct or indirect, are one of the most important consequences of bioenergy production. While direct land use changes are more easily assessed locally, indirect land use changes exceed the company level and need to be considered at a global scale. Methodologies for dealing with direct and indirect land use changes are proposed among others in the European, Dutch, British and German sustainability initiatives. This paper aims at presenting and comparing those four European initiatives, with a focus on their propositions for direct and indirect land use changes assessment. Key issues are discussed and recommendations are made for steps to overcome identified difficulties in accurately assessing the effects of indirect land use change due to bioenergy production.

    Full Text Available The Loess Plateau in China receives lots of attention from around the world. The expansion of bad agricultural practices for hundreds of years aggravated the soil erosion on the Loess Plateau, however, and a lot of efforts were and are being made to reduce the serious soil erosion as well as regional poverty. Agricultural development of the Loess Plateau is still confronted with intricate challenges such as food concerns, environment concerns, and regional poverty. The strategy of development towards sustainability offers a possible and important way to face the challenges. This study tried to develop a holistic “variation-selection-replication-retention” model to analyze the transformation of agricultural development from an evolutionary view which is generally integrative. It is indicated that policies should be lively and vibrant organisms full of innovations owning to ever-changing environment in the evolutionary view. Under this analytical framework, one possible path from serious soil erosion region to region with sustainable agriculture could be recognized in the case study of Fuxian County: serious soil erosion regions → regions with poor production conditions → production-optimized regions → regions with developed agriculture → regions with sustainable agriculture. Diversified integrative development is suggested due to regional differences and the possible developing order in Fuxian County. State-subsidized “Grain for Green” policy and diversified land use are necessary for the transformation of serious soil erosion regions which are usually trapped in regional poverty. To the transformation of regions with poor production conditions, a state-subsidized “production optimization” policy and diversified land use deserve to be considered, due to regional poverty in regions with poor production conditions. Agricultural scale operation is priority for the transformation of production-optimized regions towards

    Spinel NiCo 2 O 4 is considered a promising precious metal-free catalyst that is also carbon-free for oxygen electrocatalysis. Current efforts mainly focus on optimal chemical doping and substituent to tune its electronic structures for enhanced activity. Here, we study its morphology control and elucidate the morphology-dependent catalyst performance for bifunctional oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Three types of NiCo 2 O 4 catalysts with significantly distinct morphologies were prepared using temple-free, Pluronic-123 (P-123) soft, and SiO 2 hard templates, respectively, via hydrothermal methods followed by calcination. Whereas the hard-template yields spherelike dense structures, soft-template assists the formation of a unique nanoneedle cluster assembly containing abundant meso- and macropores. Furthermore, the effect of morphology of NiCo 2 O 4 on their corresponding bifunctional catalytic performance was systematically investigated. The flowerlike nanoneedle assembly NiCo 2 O 4 catalyst via the soft-template method exhibited the highest catalytic activity and stability for both ORR and OER. In particular, it exhibited an onset and half-wave potentials of 0.94 and 0.82 V versus reversible hydrogen electrode, respectively, for the ORR in alkaline media. Although it is still inferior to Pt, the NiCo 2 O 4 represents one of the best ORR catalyst compared to other reported carbon-free oxides. Meanwhile, remarkable OER activity and stability were achieved with an onset potential of 1.48 V and a current density of 15 mA/cm 2 at 1.6 V, showing no activity loss after 20 000 potential cycles (0-1.9 V). The demonstrated stability is even superior to Ir for the OER. The morphology-controlled approach provides an effective solution to create a robust three-dimensional architecture with increased surface areas and enhanced mass transfer. Importantly, the soft template can yield a high degree of spinel crystallinity with ideal

    In the brochure under conideration, the Federal Environment Agency (Dessau-Rosslau, Federal Republic of Germany) reports on a sustainable electricity supply in the future. The costs and benefits of the transformation to 100% renewable energy sources are considered. The Federal Environment Agency concludes: A sustainable power supply requires the transition to a fully renewable energy supply. A full supply of electricity from renewable sources by 2050 is feasible technically. Thereby electricity from wind power and solar energy may play a central role in any ambitious expansion scenarios. The cost of power generation from renewable energy already are sunk. This trend will continue. Since the conventional power generation is more expensive in the future, renewable energy pays off more and more. Environmentally harmful subsidies and the lack of consideration of the social costs caused by the fossil and nuclear power generation massively distort the competition at the expense of renewable energy. The transformation of the energy system is worthwhile macroeconomically. The promotion of renewable energies avoids social follow-up costs caused by environmental damages and health related harms. Jobs are created. The regional value added is increased. It also improves the competitiveness of the fast-growing world markets for renewable energy technologies.

    Our way of constructing our buildings, our life-style, our housing patterns, as well as our mobility habits, increasingly place stress on the environment and endanger the basis of existence of many living creatures on this planet. Mankind can carry on ignoring the limits of tolerance of their natural environment. However, they must then learn to cope with increasing damage caused by natural catastrophes to which they have contributed. Our extensive use of raw materials pushes the limits as well. Peak-Oil will soon be reached, although the demand for oil will continue to increase strongly. Therefore, we have to dismiss our wasteful technologies, architecture, living standards and housing patterns, established during the 'fossil age'. Construction, development, use, modernisation and repair of buildings and infrastructure take up an unacceptably large amount of surface area and cause a major part of the demand for energy and raw materials in Germany. There are excellent and worthwhile alternatives to the common and familiar habits, patterns and designs. This brochure indicates how sustainable alternatives can be found in the construction and housing sector. A compilation of alternatives - the so-called 'Sustainability scenario' - provides an excellent overview of the amazingly wide spectrum we have to satisfy our housing requirements at a high level and - at the same time - wasting considerably less natural resources. The supposed measures follow the principles 'Return from greenfield to central urban areas' and 'Rather improve the fabric of existing buildings than construct new ones'. The first principle also links to other measures for a mobility less depending on oil and less harmful to our climate. Politicians, leaders of the construction and housing industry, architects, home owners and tenants can positively shape the presented spectrum. By abolishing the home building subsidy and by promoting the energy saving

    Sustainability is the theme of our time and also the grandest challenge to humanity. Since the 1970s, the term, sustainable development, has frequently appeared in the scientific literature, governmental documents, media promotions for public goods, and commercial advertisements. However, the science that provides the theoretical foundation and practical guidance for sustainable development--sustainability science--only began to emerge in the beginning of the 21st century. Nevertheless, the field has rapidly developed in depth and expanded in scope during the past decade, with its core concepts and research methods coalescing. China, as the most populous country in the world and home to the philosophical root of sustainability science-the unity of man and nature, is obligated to take upon the challenge of our time, to facilitate global sustainability while pursuing the Chinese Dream, and to play a leading role in the development of sustainability science. Toward this grandiose goal, this paper presents the first Chinese introduction to sustainability science, which discusses its basic concepts, research questions, and future directions. Sustainability science is the study of the dynamic relationship between humans and the environment, particularly focusing on the vulnerability, robustness, resilience, and stability of the coupled human-environment system. It is a transdisciplinary science that integrates natural sciences with humanities and social sciences. It hinges on the environment-economy-society nexus, and merges basic and applied research. The key components of sustainability often change with time, place, and culture, and thus sustainability science needs to emphasize multi-scale studies in space and time, with emphasis on landscapes and regions over a horizon of 50 to 100 years. It needs to focus on the relationship between ecosystem services and human well-being, as influenced by biodiversity and ecosystem processes as well as climate change, land use

    Chalcopyrite-based solar cell deposited by solution processes is of great research interest because of the ease of fabrication and cost effectiveness. Despite the initial promising results, most of the reported methods encounter challenges such as limited grain growth, carbon-rich interlayer, high thermal budget, and the presence of secondary Cu-rich phases, which limit the power conversion efficiency (PCE). In this paper, we develop a new technique to deposit large grain, carbon-free CISSe absorber layers from aqueous nanoparticle/precursor mixture which resulted in a solar cell with PCE of 6.2%. CuCl2, InCl3, and thiourea were mixed with CuS and In2S3 nanoparticles in water to form the unique nanoparticle/precursor solution. The Carbon layer formation was prevented because organic solvents were not used in the precursor. The copper-rich (CuS) nanoparticles were intentionally introduced as nucleation sites which accelerate grain growth. In the presence of nanoparticles, the grain size of CISSe film increased by a factor of 7 and the power conversion efficiency of the solar cell is 85% higher than the device without nanoparticle. This idea of using nanoparticles as a means to promote grain growth can be further exploited for other types of chalcopyrite thin film deposited by solution methods.

    National Immunisation Technical Advisory Groups (NITAGs) provide independent guidance to health ministries to support evidence-based and nationally relevant immunisation decisions. We examined NITAGs' value, sustainability, and need for support in low and middle-income countries, drawing from a mixed-methods study including 130 global and national-level key informant interviews. NITAGs were particularly valued for providing independent and nationally owned evidence-based decision-making (EBDM), but needed to be integrated within national processes to effectively balance independence and influence. Participants agreed that most NITAGs, being relatively new, would need developmental and strengthening support for at least a decade. While national governments could support NITAG functioning, external support is likely needed for requisite capacity building. This might come from Gavi mechanisms and WHO, but would require alignment among stakeholders to be effective.

    Full Text Available This paper describes one of the major challenges of the future: the sustainable development of the society. Sustainability is now increasingly recognized as central to the growth of emerging market economies. For the banking sector, this represents both a demand for greater social and environmental responsibility as well as a new landscape of business opportunity. Several years ago, the main part of the banks did not consider the social and environmental problems relevant for their operations. Recently, the banks began to realize the major impact of the sustainable development over the way of ulterior development of the society and, implicitly over the way of creating of the banking value in the future. In this context, the development of a banking management system, based on sustainable principles represents one of the provocations of these days.Starting from literature in the sustainable banking management field in this paper are presented several relevant issues related to risk management in the context of sustainable banking financing: the need to implement the sustainable management principles in financial and banking industry; the role of banks in sustainable development of society; social and environmental risk management policies, events that have shaped the role of the banking sector in sustainable development; international standards regarding sustainable banking management such us: Equator Principles for sustainable investment projects’ financing or GRI principles for sustainable reporting. Furthermore, we developed a practical case study related to the implementation of sustainable banking management at Bank of America.

    The paper presents an overview of sustainable energy development and is aimed to emphasize the important aspects relevant to this activity. A short introduction, related to the present energy outlook with a survey of available data, is presented. This gives the possibility to assess the motivation for a sustainable energy development. Special attention is devoted to the definition of sustainability and its generic meaning. In this respect, particular attention is devoted to the discussion of different aspects of sustainability in the present world. In order to present an engineering approach to the sustainable development, attention is devoted to the review of sustainability criterions as they have to be introduced in the future products. The main emphasis is given to review a potential development in the energy engineering science which may lead to a sustainable energy development. Seven major areas are listed with specific problems and their relevance to the sustainable energy development. This includes the following areas: energy resources and development: efficiency assessment; clean air technologies; information technologies; new and renewable energy resources; environment capacity; mitigation of nuclear power threat to the environment. The education system is the milestone for any economic development. In this respect, sustainable energy development will require special attention to be devoted to the new development of the education system. The distance learning education system is envisages as the potential option for the knowledge dissemination of the new energy technologies. (Author)

    Recent studies have highlighted the importance of management in the health care sector. Positive correlations have been found between clinical and economic performance. Although there is still controversy regarding what kind of management and which managers should lead health care organizations and health systems, we now have interesting evidence to analyze. Starting with a systematic review of the literature, this article presents and discusses the streams of knowledge regarding how management can influence the quality and sustainability of health systems and organizations. Through the analysis of 37 studies, we found that the performance of health care systems and organizations seems to be correlated with management practices, leadership, manager characteristics, and cultural attributes that are associated with managerial values and approaches. There is also evidence that health care organizations run by doctors perform better than others. Finally, we provide a roadmap that indicates how the relationship between the management and performance of health systems and organizations can be further and more effectively investigated.

    Microalgae have recently attracted considerable interest worldwide, due to their extensive application potential in the renewable energy, biopharmaceutical, and nutraceutical industries. Microalgae are renewable, sustainable, and economical sources of biofuels, bioactive medicinal products, and food ingredients. Several microalgae species have been investigated for their potential as value-added products with remarkable pharmacological and biological qualities. As biofuels, they are a perfect substitute to liquid fossil fuels with respect to cost, renewability, and environmental concerns. Microalgae have a significant ability to convert atmospheric CO 2 to useful products such as carbohydrates, lipids, and other bioactive metabolites. Although microalgae are feasible sources for bioenergy and biopharmaceuticals in general, some limitations and challenges remain, which must be overcome to upgrade the technology from pilot-phase to industrial level. The most challenging and crucial issues are enhancing microalgae growth rate and product synthesis, dewatering algae culture for biomass production, pretreating biomass, and optimizing the fermentation process in case of algal bioethanol production. The present review describes the advantages of microalgae for the production of biofuels and various bioactive compounds and discusses culturing parameters.

    This paper summarises the main points of a review of the Status of Health Librarianship & Libraries in Ireland (SHELLI). The review was commissioned to gain a broad understanding of what was happening in practice in Ireland; acquire knowledge about international best practice, and to inform strategic plans to develop and sustain health libraries and librarianship in Ireland. A Mixed Methods approach was used: a literature review; an online survey distributed to health librarians; Semi structured interviews with key stakeholders; a focus group drawing participants from the survey. All evidence was triangulated. New roles for health librarians needed development and the changing educational needs of health librarians warranted attention. Increased collaboration across institutional boundaries needed more consideration, especially in relation to access to e-resources. Marketing of library services was crucial. Irish health library standards, needed to be updated and enforced and a proper evidence base established. The literature provided a number of examples of potentially useful initiatives. A strategic plan of action was drawn up in three areas: (i) to identify champions and promote visibility of health service libraries, (ii) to establish a body of evidence and (iii) to support service development and staff mentoring. © 2013 The authors.

    The consequences of the 2013-16 Ebola Zaire virus disease epidemic in West Africa were grave. The economies, healthcare systems and communities of Guinea, Sierra Leone and Liberia were devastated by over 18 months of active Ebola virus transmission, followed by sporadic resurgences potentially related to sexual transmission by survivors with viral persistence in body fluids following recovery. The need to develop and implement strategies to prevent and mitigate future outbreaks is now beyond dispute. The potential for unpredictable outbreaks of indeterminate duration, and control challenges posed by the possibility of sporadic re-emergence, mean that implementation of an effective vaccination program for outbreak containment necessitates a vaccine providing durable immunity. Heterologous prime-boost vaccine regimens deliver the same or similar antigens through different vaccine types, the first to prime and the second to boost the immune system. Ad26.ZEBOV/MVA-BN-Filo is an investigational Ebola Zaire vaccine regimen that uses this heterologous prime-boost approach. Preliminary Phase 1 data suggest that Ad26.ZEBOV/MVA-BN-Filo confers durable immunity for at least 240 d and is well-tolerated with a good safety profile. This regimen may therefore be suitable for prophylactic use in a regional or targeted population vaccination strategy, and could potentially aid prevention and control of future Ebola outbreaks.

    Planning is an integral element of good management and necessary to anticipate events not merely respond to them. Projecting the quantity and spatial distribution of urban growth is essential to effectively plan for the delivery of city services and to evaluate potential environmental impacts. The major drivers of growth in large urban areas are increasing population, employment opportunities, and quality of life attractors such as a favorable climate and recreation opportunities. The spatial distribution of urban growth is dictated by the amount and location of developable land, topography, energy and water resources, transportation network, climate change, and the existing land use configuration. The Atlanta region is growing very rapidly both in population and the consumption of forestland or low-density residential development. Air pollution and water availability are significant ongoing environmental issues. The Prescott Spatial Growth Model (SGM) was used to make growth projections for the metropolitan Atlanta region to 2010,2020 and 2030 and results used for environmental assessment in both business as usual and smart growth scenarios. The Prescott SGM is a tool that uses an ESRI ArcView extension and can be applied at the parcel level or more coarse spatial scales and can accommodate a wide range of user inputs to develop any number of growth rules each of which can be weighted depending on growth assumptions. These projections were used in conjunction with meteorological and air quality models to evaluate future environmental impacts. This presentation will focus on the application of the SGM to the 13-County Atlanta Regional Commission planning jurisdiction as a case study. The SGM will be described, including how rule sets are developed and the decision process for allocation of future development to available land use categories. Data inputs required to effectively run the model will be discussed. Spatial growth projections for ten, twenty, and thirty

    This project initiates an integrated-landscape conservation approach within the Northern Cumberlands Project Area in Tennessee and Kentucky. The mixed mesophytic forests within the Cumberland Plateau and Mountains are among the most diverse in North America; however, these forests have been impacted by and remain threatened from changes in land use across this landscape. The integrated-landscape conservation approach presented in this report outlines a sequence of six conservation steps. This report considers the first three of these steps in two, successive stages. Stage 1 compares desired future conditions (DFCs) and current prevailing conditions (CPCs) at the landscape-scale utilizing remote sensing imagery, remnant forests, and descriptions of historical forest types within the Cumberland Plateau. Subsequently, Stage 2 compares DFCs and CPCs for at-risk forest types identified in Stage 1 utilizing structural, compositional, or functional attributes from USFS Forest Inventory and Analysis data. Ecological indicators will be developed from each stage that express the gaps between these two realizations of the landscape. The results from these first three steps will directly contribute to the final three steps of the integrated-landscape conservation approach by providing guidance for the generation of new conservation strategies in the Northern Cumberland Plateau and Mountains.

    The European Union is facing major challenges in the energy field - growing import dependency, the need for substantial investment and lack of competitive energy market. It has adopted binding legislation and non-binding recommendations, but they do not suffice. The latest Green paper identifies diversification of energy mix as one of the key areas, where further action is needed, if Europe is to overcome this crisis. Renewable energy is recognised as a relevant factor in improving security of energy supply, since it increases the share of indigenous energy and thus provides a more balanced and diversified energy mix. Slovenia's energy mix includes 11 % of renewables. In our electricity mix the share of renewables is higher, 27,6 %.The estimations show that by 2015 13,3 % of primary energy use will come from renewable sources. Our current strategy in the field of renewable energy sources is to increase their share in overall energy balance sheet to 12 % in 2010 and to increase their share in electricity production to 33,6 % in 2010. But Slovenia will have to take into account new ambitious targets the European Commission recommended recently, while trying to determine the optimally balanced diversification of energy sources in the future.

    It is shown that present energy strategy requires adaptation of new criterions to be followed in the future energy system development. No doubt that there is a link between energy consumption and environment capacity reduction. This is an alarming sign, which recently has become the leading theme for our near and distant future. Modern engineering science has to be oriented to those areas which may directly assist in our future energy planning. In this respect, it is demanding need that our attention be oriented to the global aspect og the energy development. Modern technology will help to adopt essential principles of the sustainable energy development. With the appropriate renewable energy resources introduction in our energy future and with the increase of safety of nuclear energy, it will be possible to comply with the main principles to be adapted in the sustainable energy strategy. in order to promote the sustainable energy development the respective education system is required. It was recognized that the present energy education system can not meet future demand for the knowledge dissemination. It was shown that the potential option for the future education system is the distance learning with multimedia telematic system. (authors). 46 refs, 14 figs, 1 tab

    None of the eight Millennium Development Goals (MDGs) adopted by the United Nations in 2000 directly addressed energy, although for nearly all of them - from eradicating poverty and hunger to improving education and health - progress has depended on greater access to modern energy. Thirteen years later, energy is being given more attention. The target date for the MDGs is 2015, and in 2012 the UN began deliberations to develop sustainable development goals to guide support for sustainable development beyond 2015. The Future We Want, the outcome document of the 2012 United Nations Conference on Sustainable Development (also known as Rio+20) gives energy a central role: ''We recognize the critical role that energy plays in the development process, as access to sustainable modern energy services contributes to poverty eradication, saves lives, improves health and helps provide for basic human needs''

    2007-01-01

    At the U.N. Commission on Sustainable Development (CSD), the role of nuclear power for a carbon free emission supply of energy is now being recognized although with certain reticence or opposition. Such recognition is taking place at the current cycle of discussions devoted to sustainable energy, industrial development, atmospheric pollution and climate change issues. This paper focuses on the arguments and facts provided during CSD deliberations for considering nuclear energy as a valid option: all available energy sources will need to be considered for an adjustment to a world that requires much less carbon liberation to the environment; in the transportation sector, actions need to be urgently implemented for promoting cleaner fuels and more efficient vehicles; massive reduction of greenhouse gas emissions must be urgently implemented in order to mitigate the impacts of global warming; sustainable energy solutions for developed economies are not always adequate in developing countries; the development evolution requires specifically tailored solutions to conditions of large annual growth-rates of energy demand. Consequently, nuclear power will provide the answer to many of these problems. (Author)

    2014-01-01

    Aim The aim of this study was to describe, explore and explain the concept of sustainability in nursing. Background Although researchers in nursing and medicine have emphasised the issue of sustainability and health, the concept of sustainability in nursing is undefined and poorly researched. A need exists for theoretical and empirical studies of sustainability in nursing. Design Concept analysis as developed by Walker and Avant. Method Data were derived from dictionaries, international healthcare organisations and literature searches in the CINAHL and MEDLINE databases. Inclusive years for the search ranged from 1990 to 2012. A total of fourteen articles were found that referred to sustainability in nursing. Results Sustainability in nursing involves six defining attributes: ecology, environment, future, globalism, holism and maintenance. Antecedents of sustainability require climate change, environmental impact and awareness, confidence in the future, responsibility and a willingness to change. Consequences of sustainability in nursing include education in the areas of ecology, environment and sustainable development as well as sustainability as a part of nursing academic programs and in the description of the academic subject of nursing. Sustainability should also be part of national and international healthcare organisations. The concept was clarified herein by giving it a definition. Conclusion Sustainability in nursing was explored and found to contribute to sustainable development, with the ultimate goal of maintaining an environment that does not harm current and future generations′ opportunities for good health. This concept analysis provides recommendations for the healthcare sector to incorporate sustainability and provides recommendations for future research. PMID:24602178

  2. The Pitfalls of Sustainability Policies: Insights into Plural Sustainabilities

    Directory of Open Access Journals (Sweden)

    François Mancebo

    2013-05-01

    Full Text Available A lot can be learned from the numerous pitfalls of sustainable development implementation: they outline how collective representation, short term interests and balance of power can undermine sustainability. For instance, the usefulness of global institutions in dealing with sustainable development is questionable as most are skewed toward the interests and perceptions of developed countries. The notion of sustainable development itself induces a profound cleavage between academic authors and the actors of its implementation, some of whom confuse it with sustainable growth (which favors spatial equity, whilst the others with environment management (which favors intergenerational equity. This polarization is a real problem, since originally, "Our Common Future" report promotes an inclusive approach, able to cope with both equities simultaneously. Finally, if there are obligations toward future generations, there are also obligations toward the current generation. The key issue for effective sustainability policies should be making them acceptable to everyone by including the expectations of local societies and communities. As a matter of consequence, universal solutions do not exist. They would not meet the specificities of local circumstances. The traditional prescriptive sustainable development model should give way to flexible plural sustainabilities. Singular, top-down, global-to-local approaches to sustainable development should be substituted for multiple sustainabilities.

    Airship Industry Study: In 2015, NASA Ames Research Center completed a study of the overall airship industry. The project called for a report that describes airship concepts proposed or projects initiated in recent years, airship performance or capability targets, and the missions these activities were addressing. The resulting report details the principal technical features of these airships, the proposed value/advantages of the features, notional concepts of operation, and challenges associated with such vehicles. The study investigated the current status and near-term prospects of these airship development activities, whether they are active or, if curtailed, the circumstances and possible reasons for that conclusion, including technical, business, or other mitigating factors. This presentation provides highlights of the Airship Industry Study investigations, findings, and recommendations. UAS Carrier Concept: The advantages of utilizing an airship as an airborne carrier for support and deployment of Unmanned Aircraft Systems (UAS) are examined. Whether as a stand-alone platform or in concert with conventional aircraft, the airship UAS carrier provides a number of compelling benefits for both military and civilian missions. As a mobile base it can remain operational despite political fallout that may render ground or ocean based UAS sites unavailable. It offers the psychological impact of a power projection tool that has few geographical limits, and holds promise as a new method for cost-saving intelligence gathering. It is also adaptable for civilian variants for supporting: emergency response, security/surveillance, delivery of medical/food supplies, as well as commercial package delivery to metropolitan and remote communities.

    2010-05-01

    The application of bioclimatic principles is a critical factor in reducing energy consumption and CO2 emissions. This poster develops a sequence of experiments and building working models in order to form students of secondary school and make progress towards real applications of new energy technologies. The activity has been carried out by 14 and 15-year-old students using a Power House building kit. Scientific method and Information and Communication Technologies (ICT) were used as an effective system of acquiring new knowledge. Students were asked to form cooperative groups. Firstly, each group had to choose the best location and orientation in the imaginary Dragon Island for the construction of the house. The house consisted of eight Styrofoam parts and one transparent plastic part. The Styrofoam parts formed the house structure (floor, walls and roof) with two interior chambers and the attached greenhouse. Once the house was assembled in a few steps, it was ready for the students to start adding more components. Students then conducted several experiments related to the heat and light energy of the Sun and the energy of the wind. Some of the experiments and building projects realized were: how to capture the Sun to heat the house by passive solar heating, how to collect the Sun's rays to heat water using a Sun Collector and how to extract electricity current from Sun Power station and from wind power plant. For most of the assays it was necessary to record the temperature and students used for that purpose a temperature sensor that comes with Multilog Pro, a portable, graphic data collection and analysis system. Groups of students were really engaged in the project and each of them ran a different test with the house. Finally they proved if their initial hypothesis was correct and they had to expose the results to the rest of the class members. Students demonstrated how we can transform and use renewable forms of energy. With the experiments students demonstrated that the air can circulate between the house and the greenhouse through the windows. The heated air in the greenhouse rose through the windows into the main house. It was cooled off as it delivered heat and returned again to the greenhouse. It happened naturally due to the materials and the configuration of the house. A solar collector gathered heat from the Sun in order to heat water until 40° C, what was enough for showering, laundry, and washing dishes. Solar cells and homemade wind power unit delivered electricity to light up a small light bulb. With these experiments and building kit we explored and used natural, renewable forms of energy. These are forms of energy that we can use without damaging our natural environment and ourselves. Perhaps this kit will give students the incentive to build something on a larger scale after they have learned from the smaller scale model devices.

    Multiple factors influence individuals' health status. Their impact is difficult to quantify as it is their interaction. Aim of the current work is to develop guidelines to support designers to promote health in the residential environment and to apply them through an evaluation system to certify the level of health performance. Politecnico di Milano, in collaboration with the Local Health Authorities of Milan and Empoli through analysis of needs performance and numerous multidisciplinary meetings, has produced a design guide (Healthy Design Guide - HeDe) and an evaluation system to certify the level of health performance. This system was tested on the Milan metropolitan area. The experiment was carried out on a sample of 30 private residences, with an overall floor area ranging between 90 and 150 square meters, new or recently renovated. The tool works but at the same time it also shows that too often design choices are made for aesthetic or economic reasons rather than a real need for health and wellness. It is becoming increasingly important to strengthen synergies and multidisciplinary collaborations to achieve shared performance indications and to make a systematic review of the regulatory tools to protect public health.

Based on the discourse within the fields of risk management and sustainable urban water management, we discuss the necessity of assessing the sustainability of flood...... risk management, and propose an evaluation framework for doing so. We argue that it is necessary to include quantitative sustainability measures in flood risk management in order to exclude unsustainable solutions. Furthermore, we use the concept of absolute sustainability to discuss the prospects...... of maintaining current service levels without compromising future generation’s entitlement of services. Discussions on the sustainability of different overall flood risk schemes must take place. Fundamental changes in the approaches will require fundamental changes in the mind-sets of practitioners as well...

    Judging from the number of communities and cities striving or claiming to be sustainable and how often eco-development is invoked as the means for urban regeneration, it appears that sustainable and eco-development have become “the leading paradigm within urban development” (Whitehead 2003......), urban design competitions are understudied mechanisms for bringing about field level changes. Drawing on actor network theory, this paper examines how urban design competitions may bring about changes within the professional field through the use of intermediaries such as a sustainable planning....../assessment tool.

    Andersen, Nicolai Bo

    This paper is about sustainable transformation with a particular focus on listed buildings. It is based on the notion that sustainability is not just a question of energy conditions, but also about the building being robust. Robust architecture means that the building can be maintained and rebuilt......, that it can be adapted to changing functional needs, and that it has an architectural and cultural value. A specific proposal for a transformation that enhances the architectural qualities and building heritage values of an existing building forms the empirical material, which is discussed using different...... theoretical lenses. It is proposed that three parameters concerning the ꞌtransformabilityꞌ of the building can contribute to a more nuanced understanding of sustainable transformation: technical aspects, programmatic requirements and narrative value. It is proposed that the concept of ꞌsustainable...

    The intention of this chapter is to explore the role of consumption and consumers in relation to sustainability transition processes and wider systemic transformations. In contrast to the individualistic focus in much research on sustainable consumption, the embeddedness of consumption activities...... in wider social, economic and technological frameworks is emphasised. In particular, the chapter is inspired by practice theory and transition theory. First, various trends in consumption are outlined to highlight some of the challenges for sustainability transitions. Then, it is discussed how consumption...... patterns are shaped over time and what should be considered in sustainability strategies. While discussions on consumption often take their point of departure in the perspective of the individual and then zoom to the wider context, the present approach is the opposite. The outline starts with the basic...

  18. Local Sustainability

    Carrizosa Umana, Julio

    1998-01-01

    The current polemic about the possibilities of sustainable development has led to a renovated interest for the topic of the sustainability of the communities and the local sustainability. In front of the global sustainability whose conditions have been exposed by systemic ecologists and for macro economists, the sustainability of specific places arises in the planet whose conditions are object of study of the ecology of landscapes, of the ecological economy, of the cultural anthropology, of the environmental sociology and naturally, of the integral environmentalism. In this discussion the Colombian case charges unusual interest to be one of the few countries of Latin America, where a very dense net of municipalities exists, each one with its urban helmet and with a position and some functions defined by the political constitution of the nation. This net of municipalities and of urban helmets it also constitutes net of alternative to the current macro-cephalic situation. As well as Bogota grew, in a hundred years, of less than a hundred thousand inhabitants to six million inhabitants, each one of these municipalities contains a potential of growth that depends on the characteristics of its ecological, social, economic and politic sustainability
