    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.

  3. Local Institutional Development and Organizational Change for Advancing Sustainable Urban Water Futures

    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.

    2017-01-01

    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.

  6. 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.

  7. Prediction of future urban growth using CA-Markov for urban sustainability planning of Banda Aceh, Indonesia

    2018-03-01

    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.

    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.

  14. Urban Stormwater Quality: Linking Pesticide Variability To Our Sustainable Water Future

    Science.gov (United States)

    Rippy, M.; Deletic, A.; Gernjak, W.

    2015-12-01

    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.

  17. Interpreting Sustainability for Urban Forests

    Camilo Ordóñez

    2010-06-01

    Full Text Available Incisive interpretations of urban-forest sustainability are important in furthering our understanding of how to sustain the myriad values associated with urban forests. Our analysis of earlier interpretations reveals conceptual gaps. These interpretations are attached to restrictive definitions of a sustainable urban forest and limited to a rather mechanical view of maintaining the biophysical structure of trees. The probing of three conceptual domains (urban forest concepts, sustainable development, and sustainable forest management leads to a broader interpretation of urban-forest sustainability as the process of sustaining urban forest values through time and across space. We propose that values—and not services, benefits, functions or goods—is a superior concept to refer to what is to be sustained in and by an urban forest.

    Full Text Available Environmental protection has become a common issue in every area, but extremely important for the domains which deal with intensive energy consumption as it is the case of the transportation. Achieving the sustainable cities on the other hand, is also focused on the protection of the environment in order to provide a higher quality of life for the population. Therefore it is considered that by improving the urban transportation planning additional benefits could be provided for both the environment and the sustainable development of the cities. One possibility is to supplement the traditionally land-use plans with the transportrelated zones analysis, where the city is divided in public transport, pedestrian and caroriented zones. Analyzing the transport-related zones of a city is important as it provides additional information in the assessment of the development trend. The process of zoning was conducted for the city of Cluj-Napoca, Romania. In this paper, the outcome of the zoning was analyzed for a more comprehensive review of the urban transport in order to attain a sustainable-oriented approach of the urban area development.

  19. Reconfiguring Urban Sustainability Transitions, Analysing Multiplicity

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available Cities, and the networked infrastructures that sustain urban life, are seen as crucial sites for creating more sustainable futures. Yet, although there are many plans, the realisation of sustainable urban infrastructures on the ground is uneven. To develop better ways of understanding why this is the case, the paper makes a conceptual contribution by engaging with current understanding of urban sustainability transitions, using urban sustainable mobility as a reference point. It extends these insights to argue that urban transitions are not about technological or social innovation per se, but about how multiple innovations are experimented with, combined and reconfigured in existing urban contexts and how such processes are governed. There are potentially many ways in which urban sustainable mobility can be reconfigured contextually. Innovation is in the particular form of reconfiguration rather than individual technologies. To make analytical sense of this multiplicity, a preliminary framework is developed that offers the potential to think about urban transitions as contextual and reconfigurational. We argue that there is a need to embrace multiplicity and to understand its relationships to forms of reconfiguration, through empirical exploration and further theoretical and conceptual development. The preliminary framework is a contribution to doing so and we set out future directions for research.

    Cities are rapidly expanding in size, wealth and power, with some now larger than nation states. Smart city solutions and strong global urban networks are developing to manage massive urban growth. However, cities exist within a wider system and it may take more than technological advances, innovation and city autonomy to develop a sustainable urban future.

  1. Establishing sustainable strategies in urban underground engineering.

    2004-07-01

    Growth of urban areas, the corresponding increased demand for utility services and the possibility of new types of utility systems are overcrowding near surface underground space with urban utilities. Available subsurface space will continue to diminish to the point where utilidors (utility tunnels) may become inevitable. Establishing future sustainable strategies in urban underground engineering consists of the ability to lessen the use of traditional trenching. There is an increasing interest in utility tunnels for urban areas as a sustainable technique to avoid congestion of the subsurface. One of the principal advantages of utility tunnels is the substantially lower environmental impact compared with common trenches. Implementing these underground facilities is retarded most by the initial cost and management procedures. The habitual procedure is to meet problems as they arise in current practice. The moral imperative of sustainable strategies fails to confront the economic and political conflicts of interest. Municipal engineers should act as a key enabler in urban underground sustainable development.

  2. The future is urban.

    Science.gov (United States)

    1992-05-01

    Urban centers are growing due to natural increase and the movement of people from rural areas. Urban areas are the traditional centers of trade, science, and culture, but growth over a threshold results in crime, congestion, and pollution. Sustainability is threatened in modern towns that are dependent on other sources for food, fuel, or water. Housing, water, food supplies, and sanitation, communication, and transportation services are threatened in rapidly growing cities. In 1990 45/100 people lived in towns or cities. Hyper-cities have grown in number to 20, of which 14 are in developing countries. 83% of world population increase is expected to occur in cities. In 48 countries with faster population growth cities had growth rates averaging about 6.1% per year, and the urban share of total population averaged 2.8%. In 49 countries with slower population growth, urban growth rates averaged only 3.6% per year, and the urban share of total population averaged about 1.8%. Squatter settlements are endemic to urban areas that are congested and without basic services, limited housing particularly for the poor, and few job opportunities. The number of street children in urban areas has risen. This child population is subjected to low wages, overwork, auto accidents, poor health, and lack of social services. Malnutrition is a more serious issue in urban areas. In the Philippines malnutrition is 3% nationally and 9% in Metro Manila. Rural land reform in the Philippines is no longer a viable solution. In Metro Manila squatters are expected to increase in number to 4 million people by the year 2000, which would be almost 50% of total population. The squatter areas are areas of neglect, decay, and poverty. Cities are viewed as development's "blind alleys."

    This paper explores the development of the urban forest in East Jakarta. By 2030 Jakarta area has a target of 30% green area covering 19,845 hectares, including urban forest covering an area of 4,631 hectares. In 2015, the city forest is only 646 hectares, while the city requires 3,985 hectares of new land Urban forest growth from year to year showed a marked decrease with increasing land area awoke to commercial functions, environmental conditions encourage the development of the city to become unsustainable. This research aims to support sustainable urban development and ecological balance through the revitalization of green areas and urban development. Analytical methods for urban forest area is calculated based on the amount of CO2 that comes from people, vehicles, and industrial. Urban spatial analysis based on satellite image data, using a GIS program is an analysis tool to determine the distribution and growth patterns of green areas. This paper uses a dynamic system model to simulate the conditions of the region against intervention to be performed on potential areas for development of urban forests. The result is a model urban forest area is integrated with a social and economic function to encourage the development of sustainable cities.

  5. A Systematic Review of Urban Sustainability Assessment Literature

    2017-11-01

    Full Text Available As the world rapidly urbanizes, there is much focus on achieving sustainability outcomes within cities. Accomplishing this goal requires not only envisioning sustainable cities and implementing strategies, but it also demands assessing progress towards sustainable urban development. Despite a growing literature on sustainability assessment, there is room to further understand the application of sustainability assessment in urban contexts. This paper presents a systematic review of urban sustainability assessment literature to (1 identify the most common methods used for urban sustainability assessment, (2 identify the most common framings for urban sustainability assessment, and (3 identify the most common categories for organizing indicators that measure urban sustainability. This research finds that urban sustainability assessment in general lacks a unifying framing and that it could be better aligned with common sustainability principles. The paper provides recommendations for future urban sustainability assessment research, including the employment of mixed-methods research among other strategies. In closing, this research offers a generic framework around which to structure urban sustainability assessment and within which to assign indicators for measuring progress towards sustainable urban development.

  6. Governance of urban transitions: towards sustainable resource efficient urban infrastructures

    Science.gov (United States)

    Swilling, Mark; Hajer, Maarten

    2017-12-01

    The transition to sustainable resource efficient cities calls for new governance arrangements. The awareness that the doubling of the global urban population will result in unsustainable levels of demand for natural resources requires changes in the existing socio-technical systems. Domestic material consumption could go up from 40 billion tons in 2010, to 89 billion tons by 2050. While there are a number of socio-technical alternatives that could result in significant improvements in the resource efficiency of urban systems in developed and developing countries (specifically bus-rapid transit, district energy systems and green buildings), we need to rethink the urban governance arrangements to get to this alternative pathway. We note modes of urban governance have changed over the past century as economic and urban development paradigms have shifted at the national and global levels. This time round we identify cities as leading actors in the transition to more sustainable modes of production and consumption as articulated in the Sustainable Development Goals. This has resulted in a surge of urban experimentation across all world regions, both North and South. Building on this empirically observable trend we suggest this can also be seen as a building block of a new urban governance paradigm. An ‘entrepreneurial urban governance’ is proposed that envisages an active and goal-setting role for the state, but in ways that allows broader coalitions of urban ‘agents of change’ to emerge. This entrepreneurial urban governance fosters and promotes experimentation rather than suppressing the myriad of such initiatives across the globe, and connects to global city networks for systemic learning between cities. Experimentation needs to result in a contextually appropriate balance between economic, social, technological and sustainable development. A full and detailed elaboration of the arguments and sources for this article can be found in chapter 6 of Swilling M et

    2006-06-01

    Full Text Available Ecological research targeting sustainable urban landscapes needs to include findings and methods from many lines of ecological research, such as the link between biodiversity and ecosystem function, the role of humans in ecosystems, landscape connectivity, and resilience. This paper reviews and highlights the importance of these issues for sustainable use of ecosystem services, which is argued to be one aspect of sustainable cities. The paper stresses the need to include social and economic factors when analyzing urban landscapes. Spatially explicit data can be used to assess the roles different green areas have in providing people with ecosystem services, and whether people actually have access to the services. Such data can also be used to assess connectivity and heterogeneity, both argued to be central for continuous, long-term provision of these services, and to determine the role urban form has for sustainability.

  9. Toward sustainable energy futures

    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.

    Requirements for the assessment tools of buildings have increased, assessing of building components or separate buildings is not enough. Neighbourhoods, built environment, public transportations, and services, should be considered simultaneously. Number of population living in urban areas is high and increasing rapidly. Urbanisation is a major concern due to its detrimental effects on the environment. The aim of this study is to clarify the field of assessment tools for urban communities by analysing the current situation. The focus is on internationally well known assessment tools; BREEAM Communities, CASBEE for Urban Development and LEED for Neigborhood Development. The interest towards certification systems is increasing amongst the authorities, and especially amongst the global investors and property developers. Achieved certifications are expected to bring measureable publicity for the developers. The assessment of urban areas enables the comparison of municipalities and urban areas, and notably supports decision making processes. Authorities, city planners, and designers would benefit most from the use of the tools during the decision making process. - Highlights: ► The urban assessment tools have strong linkage to the region. ► The tools promote complementary building and retrofitting existing sites. ► Sharing knowledge and experiences is important in the development of the tools.

In so doing, however, backcasting may run the risk of obscuring significant differences in current lived experience, negating alternative problem framings and normatively derived views of what constitutes sustainability. This paper reports an innovative UK attempt...... to develop an inclusive 'bottom-up' Community Foresight process for urban sustainability research. Unlike most backcasting studies, the methodology was initially grounded in an exploration of the community participants' current lived experience and understandings of sustainability. Given the particular...... purpose of the study the primary outcome from the work was structured around the articulation of a 'community-led' agenda for urban sustainability research, rather than an explicit normative vision and transition pathway. However, the methodology could easily be adapted for use in other contexts...

    Full Text Available Urban management in any context has a different economic, social and political structure, which is in harmony with the existing models of organization. In spite of these differences, in order to reach a sustainable urban development, several different conferences should be referred to. In the “Brundtland Commission 1987” about urban sustainable development these definitions have been given: “preservation and promotion of the quality level of city life. This consists of ecology, culture, politics, economies, and social participation. However, this development should in no case weigh on and create any problems for the future generations”. In all the definitions of urban management and urban sustainable development and in any political context citizens’ participation in decision making and insistence on social justice are mentioned. The aim of this article is a descriptive, analytic, and comparative study of different models of popular participation in different developed countries. Each of these countries has different social and political structure. However they all have the same aim which is the citizens’ empowerment. To reach the ideal urban management model it is necessary to have a clear image of the place and participation of citizens in order to create a socially, economically and politically sustainable developed society.

    Full Text Available As the sustainability of contemporary cities has gained emphasis, interest in architecture has increased, due to its social and public responsibility. Since sustainability is linked to public values, research on sustainable public spaces is an important way to secure sustainability in cities. Based on this, we analyzed the sustainability of European cities by examining the design methods of public architecture according to the region. The aim of the study is to derive architectural methodology corresponding to local characteristics, and to suggest issues to consider in public architecture design to promote urban sustainability based on this. First, regarding the environmental aspect, it can be observed that there is an effort to secure sustainability. Second, in terms of social sustainability, historical value remains as a trace of architectural place, so that it continues in people’s memory. In addition, public architecture provides public places where citizens can gather and enjoy programs, while the architectural methods showed differences influenced by cultural conditions. Third, in economic sustainability, it was shown that energy saving was achieved through cost reduction through recycling of materials, facilities, or environmental factors. In conclusion, the issues to be considered in public architectural design are the voiding of urban space through architectural devices in the construction method. In other words, the intention is to form “ground” that attempts to be part of the city, and thereby create better places. Since skin and material have a deep relationship with the environment, they should have the durability and an outer skin that are suitable for the regional environment. Finally, sustainability is to be utilized through the influx of programs that meet local and environmental characteristics. Design research into public architecture that is oriented towards urban sustainability will be a task to be carried out by the

    Sustainable urban development requires the integration of environmental interests in urban planning. Although various methods of environmental assessment have been developed, plan outcomes are often disappointing due to the complex nature of decision-making in urban planning, which takes place in multiple arenas within multiple policy networks involving diverse stakeholders. We argue that the concept of ‘decision windows’ can structure this seemingly chaotic chain of interrelated decisions. First, explicitly considering the dynamics of the decision-making process, we further conceptualized decision windows as moments in an intricate web of substantively connected deliberative processes where issues are reframed within a decision-making arena, and interests may be linked within and across arenas. Adopting this perspective in two case studies, we then explored how decision windows arise, which factors determine their effectiveness and how their occurrence can be influenced so as to arrive at more sustainable solutions. We conclude that the integration of environmental interests in urban planning is highly dependent on the ability of the professionals involved to recognize and manipulate decision windows. Finally, we explore how decision windows may be opened. -- Highlights: • Decision-making about sustainable urban development occurs in networks. • The concept of ‘decision windows’ was further elaborated. • Decision windows help understand how environmental interests enter decision-making. • Decision windows can, to some extent, be influenced

    2016-08-01

    Full Text Available Urbanization, particularly in developing countries, is a major strategy for development. However, major concerns accompany it, such as air pollution, habitat destruction, and loss of arable land. In responding to these challenges, governments throughout the world have been implementing various policy mechanisms to guide the practice of urbanization towards sustainable development. It appears that there is little research investigating the outcomes of those efforts in implementing sustainable urbanization strategies. This paper provides a profile of sustainable urbanization from a global perspective. Data used for this research cover 111 countries and are collected from the World Bank database and the United Nation database. A ranking list of sustainable performance of urbanization between these countries is produced and discussed. The study suggests that countries at different stages of urbanization have achieved different levels of sustainable performance. The research results provide significant references for future study in the field of urbanization from a global perspective.

    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

    It is critical to develop urban layers for analysis sustainable urban development possibilities within planning process. Kyrenia Region has many physical, environmental or economic issues that may danger the growth possibilities in sustainable manner. From this point, this study uses different spatial layers such as slope, distance to roads, distance to central zone, vegetation, soil productivity, environmental protection zones, distance to open/green space, distance to education for supporting sustainable urban growth policies and define suitable areas for urban development within this perspective. The study tries to convert sustainable urban growth policies such as; compact growth, environmental protection, equal accessibility to basic services; into spatial layers and establish proper framework for multi criteria evaluation in Kyrenia Region within using geographical information systems. It shows suitability values for Kyrenia region and constraints zones at final section. It clearly presents the suitable areas for the sustainable urbanization and also unsuitable or risky areas for reducing the possible disasters and may happen in the future.

    This paper introduces urban land teleconnections as a conceptual framework that explicitly links land changes to underlying urbanization dynamics. We illustrate how three key themes that are currently addressed separately in the urban sustainability and land change literatures can lead to incorrect conclusions and misleading results when they are not examined jointly: the traditional system of land classification that is based on discrete categories and reinforces the false idea of a rural–urban dichotomy; the spatial quantification of land change that is based on place-based relationships, ignoring the connections between distant places, especially between urban functions and rural land uses; and the implicit assumptions about path dependency and sequential land changes that underlie current conceptualizations of land transitions. We then examine several environmental “grand challenges” and discuss how urban land teleconnections could help research communities frame scientific inquiries. Finally, we point to existing analytical approaches that can be used to advance development and application of the concept. PMID:22550174

    Full Text Available The authors are of the opinion that there is no alternative to sustainable development, and discuss on thesis that sustainability is now a key driver of innovation, but also its essential requirement. This paper discusses the sustainability as a concept that has, above all, the environmental, economic, social and cultural dimension. The aim of the study was to understand sustainability as a fundamental development principle and key benchmark in organisation and development of cities in the future. This paper explores the meaning of innovation processes, sustainability and innovation in urban planning, innovative approaches to sustainable urban development, initiatives in urban sustainability, the key elements of the implementation, modalities of providing financial resources for sustainable projects of public interest, as well as identification of areas suitable for innovation in urban planning, relying on the good practices implemented through multi-sector sustainable projects. In a broader sense, the objective of this paper is to emphasize the need: to promote concept of human dimension in urban development, to direct continual urban development towards 'green' orientation, to implement innovative and smart technologies in the management of modern cities; to promote public participation and multi-sectoral policies in urban development, and to encourage and stimulate sustainable (urban innovation.

    The new millennium has seen a fresh wave of world economic development especially in the Asian-Pacific region. This has contributed to further rapid urban expansion, creating shortages of energy and resources, degradation of the environment, and changes to climatic patterns. Large-scale, new urbanization is mostly seen in developing countries but urban sprawl is also a major social problem for developed nations. Urbanization has been accelerating at a tremendous rate. According to data collected by the United Nations [1], 50 years ago less than 30% of the world population lived in cities. Now, more than 50% are living in urban settings which occupy only about 1% of the Earth's surface. During the period from 1950 to 1995, the number of cities with a population higher than one million increased from 83 to 325. By 2025 it is estimated that more than 60% of 8.3 billion people (the projected world population [1]) will be city dwellers. Urbanization and urban sprawl can affect our living quality both positively and negatively. In recent years geophysics has found significant and new applications in highly urbanized settings. Such applications are conducive to the understanding of the changes and impacts on the physical environment and play a role in developing sustainable urban infrastructure systems. We would like to refer to this field of study as 'urban geophysics'. Urban geophysics is not simply the application of geophysical exploration in the cities. Urbanization has brought about major changes to the geophysical fields of cities, including those associated with electricity, magnetism, electromagnetism and heat. An example is the increased use of electromagnetic waves in wireless communication, transportation, office automation, and computer equipment. How such an increased intensity of electromagnetic radiation affects the behaviour of charged particles in the atmosphere, the equilibrium of ecological systems, or human health, are new research frontiers to be

    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

    2017-08-01

    Full Text Available The United Arab Emirates is experiencing a challenging turn towards sustainable social housing. Conventional neighborhood planning and design principles are being replaced by those leading to more sustainable urban forms. To trace this challenging move, the research has investigated the degree of consideration of sustainable urban design principles in two social housing neighborhoods in Al Ain City in Abu Dhabi Emirate, UAE. The first represents a conventional urban form based on the neighborhood theory; the other represents the new sustainable design. The ultimate aim is to define the obstacles hindering the full achievement of a sustainable urban form in this housing type. To undertake research investigations, a matrix of the design principles of sustainable urban forms has been initiated in order to facilitate the assessment of the urban forms of the two selected urban communities. Some qualitatively measurable design elements have been defined for each of these principles. The results of the analysis of the shift from ‘conventional’ to ‘sustainable’ case studies have revealed some aspects that would prevent the attainment of fully sustainable urban forms in newly designed social housing neighborhoods. Finally, the research concludes by recommending some fundamental actions to help meet these challenges in future design.

    2014-08-01

    Full Text Available Green infrastructure ameliorates the urban heat island effect, contributes positively to liveability and enables sustainability in higher density urban environments. Greenskins (living architectures are a more specific form of green infrastructure, including green walls and green roofs, for dense urban areas. These offer a new approach for sustainable urban biophilia and some forms can be built using the ecological design principles of constructed wetlands. The paper compares findings from two urban centres in warm Mediterranean climates. In general from Adelaide, South Australia and more specifically from university collaborative projects on particular technical and social parameters necessary to sustain Greenskins in dense urban conditions in Fremantle, Western Australia. Results from trials of a prototype greywater Greenskin using vertical constructed wetland cells are reported. Through an experimental investigation of designing living green walls in urban Fremantle, this paper challenges the conventional “triple-bottom-line” approach to sustainable dense urban systems by addressing the greater aesthetic needs of sustainability and its thinking. Here landscape aesthetics looks to the collaborative fields of urban design, environmental engineering and landscape architecture to design new urban biophilic experiences and restorative landscapes for regenerative cultural pleasure, ecological responsibility, environmental stewardship and intellectual gain.

    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.

    Full Text Available Compact cities and their urban forms have implications on sustainable city development because of high density urban settlement, increased accessibility, and a balanced land use mix. This paper uses quantitative means of understanding urban morphological characteristics with reference to the differing qualities of the urban form (i.e., street patterns, building volumes, land uses and greenery. The results, based on 89 neighborhood communities of Hong Kong, show varying degrees of regional differences in the urban built form supported by numerical statistics and graphical illustrations. This paper offers empirical evidence on some morphological characteristics that can be estimated objectively using modern geospatial technologies and applied universally to inform urban planning. However, more studies linking these quantifiable measures of the physical form with sustainable urban living are needed to account for human comfort in the totality of environmental, social, and economic responsibilities.

    2014-08-01

    Urban branding is a new approach toward urban development of sustainable cities. City branding, a novel aspect of urban communication, improves marketing of the city image in various ways by converting the visual image of the city into a brand image. Unique characteristics of the city are featured and a sustainable urban image is created. This paper will focus on city branding as a powerful image-building strategy. In this realm, the branding of Stuttgart, Germany, serves as a successful model of a branding strategy. Next, branding of the city of Port Said, Egypt, will be explored. The principal aim of this paper is to describe how cities become branded; how branding succeeds; and how a viable city image is created. This paper reviews the methods used to brand cities, and concludes by emphasizing the importance of urban branding in terms of sustainability.

    Full Text Available This article investigates the process of transition from the Millennium Development Goals to Sustainable Development Goals (SDGs. The authors have set an objective to demonstrate that SD as a future form of development of civilization from the very beginning had a “target orientation” and from the beginning and anticipated realization and staging of the whole hierarchy of objectives needed for the establishment of an effective global governance. In the future, global development in its “anthropogenic” aspect will be to implement the goals and principles of SD, which will be updated with each new stage of the implementation of this kind of socio-natural evolution. The paper argues the position that the concept of SD should be radically transformed into a “global dimension.” Attention is drawn to the fact that Russia recognized another distant, but very important in the conceptual and theoretical perspective, global goal of “sustainable transition” — formation of the noosphere.

    The key workshop goal was to explore and document how NASA technologies, such as remote sensing, climate modeling, and high-end computing and visualization along with NASA assets such as Earth Observing Satellites (EOS) and Unmanned Aerial Vehicles (UAVs) can contribute to creating and managing a sustainable urban environment. The focus was on the greater Bay Area, but many aspects of the workshop were applicable to urban management at the local, regional and global scales. A secondary goal was to help NASA better understand the problems facing urban managers and to make city leaders in the Bay Area more aware of NASA's capabilities. By bringing members of these two groups together we hope to see the beginnings of new collaborations between NASA and those faced with instituting sustainable urban management in Bay Area cities.

    2018-02-01

    Full Text Available The recent discourse on sustainability science calls for interdisciplinary research. The home economics science approach ranges from individual actions to the involvement of communities and societies at large, and thus it can provide important perspectives on cultural sustainability. The aim of the research is to study the linkage between cultural sustainability and service sector education to support the creation of sustainable professions. In the present small-scale empirical study, the food service degree curriculum of a Finnish vocational college and teachers’ group interview data were analyzed to find how cultural sustainability is presented in the curriculum and how it is understood by teachers and integrated into teaching practices. Previous cultural sustainability research identifies four perspectives of cultural sustainability: (1 vitality of cultural traditions; (2 economic starting point; (3 diversity together with maintenance of local culture; and (4 possible influence on the balance between human actions and environment. Findings indicate that sustainability, including cultural sustainability, is integrated in the curriculum and considered important by teachers. Translating these into practice remains a challenge. The balance between human and nature was mostly understood as recycling, use of public transport, sustainable consumption, and taking trips to the nature nearby. Cultural sustainability as a concept is not well known, although themes such as multicultural issues, equality, charity, and environmental responsibility were included in teachers’ practical lessons daily. Feasts and celebrations in learning were opportunities to view cultural sustainability widely. This paper provides a way forward for the teachers to develop further their pedagogical practices.

  5. Managed Aquifer Recharge (MAR in Sustainable Urban Water Management

    Directory of Open Access Journals (Sweden)

    Declan Page

    2018-02-01

    Full Text Available To meet increasing urban water requirements in a sustainable way, there is a need to diversify future sources of supply and storage. However, to date, there has been a lag in the uptake of managed aquifer recharge (MAR for diversifying water sources in urban areas. This study draws on examples of the use of MAR as an approach to support sustainable urban water management. Recharged water may be sourced from a variety of sources and in urban centers, MAR provides a means to recycle underutilized urban storm water and treated wastewater to maximize their water resource potential and to minimize any detrimental effects associated with their disposal. The number, diversity and scale of urban MAR projects is growing internationally due to water shortages, fewer available dam sites, high evaporative losses from surface storages, and lower costs compared with alternatives where the conditions are favorable, including water treatment. Water quality improvements during aquifer storage are increasingly being documented at demonstration sites and more recently, full-scale operational urban schemes. This growing body of knowledge allows more confidence in understanding the potential role of aquifers in water treatment for regulators. In urban areas, confined aquifers provide better protection for waters recharged via wells to supplement potable water supplies. However, unconfined aquifers may generally be used for nonpotable purposes to substitute for municipal water supplies and, in some cases, provide adequate protection for recovery as potable water. The barriers to MAR adoption as part of sustainable urban water management include lack of awareness of recent developments and a lack of transparency in costs, but most importantly the often fragmented nature of urban water resources and environmental management.

    Rice, Marilyn; Hancock, Trevor

    2016-03-01

    In this commentary the urban setting is explored from the perspective of ecological sustainability and social equity. Urban-related issues are highlighted related to social inequality, deficits in urban infrastructures, behavior-related illnesses and risks, global ecological changes, and urban sprawl. Approaches to addressing these issues are described from the perspective of urban governance, urban planning and design, social determinants of health, health promotion, and personal and community empowerment. Examples of successful strategies are provided from Latin America, including using participatory instruments (assessments, evaluation, participatory budgeting, etc.), establishing intersectoral committees, increasing participation of civil society organizations, and developing virtual forums and networks to channel participatory and collaborative processes. A way forward is proposed, using the urban setting to show the imperative of creating intersectoral policies and programs that produce environments that are both healthy and sustainable. It will be important to include new forms of social participation and use social media to facilitate citizen decision-making and active participation of all sectors of society, especially excluded groups. © The Author(s) 2015.

This generated another hypothesis concerning the existence of an inverted-U relationship between income per capita (GDP and environmental impact. By means of a cross-country analysis, the article shows that, at least at the global scale, an Environmental Kuznets Curve (EKC does not exist, but rather an Environmental Urban Curve (EUC.

  10. Urban water sustainability: framework and application

    Directory of Open Access Journals (Sweden)

    Wu Yang

    2016-12-01

    Full Text Available Urban areas such as megacities (those with populations greater than 10 million are hotspots of global water use and thus face intense water management challenges. Urban areas are influenced by local interactions between human and natural systems and interact with distant systems through flows of water, food, energy, people, information, and capital. However, analyses of water sustainability and the management of water flows in urban areas are often fragmented. There is a strong need to apply integrated frameworks to systematically analyze urban water dynamics and factors that influence these dynamics. We apply the framework of telecoupling (socioeconomic and environmental interactions over distances to analyze urban water issues, using Beijing as a demonstration megacity. Beijing exemplifies the global water sustainability challenge for urban settings. Like many other cities, Beijing has experienced drastic reductions in quantity and quality of both surface water and groundwater over the past several decades; it relies on the import of real and virtual water from sending systems to meet its demand for clean water, and releases polluted water to other systems (spillover systems. The integrative framework we present demonstrates the importance of considering socioeconomic and environmental interactions across telecoupled human and natural systems, which include not only Beijing (the water-receiving system but also water-sending systems and spillover systems. This framework helps integrate important components of local and distant human-nature interactions and incorporates a wide range of local couplings and telecouplings that affect water dynamics, which in turn generate significant socioeconomic and environmental consequences, including feedback effects. The application of the framework to Beijing reveals many research gaps and management needs. We also provide a foundation to apply the telecoupling framework to better understand and manage water

    2012-07-01

    Full Text Available In this paper, results are reported of a technology assessment of the use and integration of decentralized energy systems and storage devices in an urban renewal area. First the general context of a different approach based on 'rethinking' and the incorporation of ongoing integration of coming economical and environmental interests on infrastructure, in relation to the sustainable urban development and regeneration from the perspective of the tripod people, technology and design is elaborated. However, this is at different scales, starting mainly from the perspective of the urban dynamics. This approach includes a renewed look at the ‘urban metabolism’ and the role of environmental technology, urban ecology and environment behavior focus. Second, the potential benefits of strategic and balanced introduction and use of decentralized devices and electric vehicles (EVs, and attached generation based on renewables are investigated in more detail in the case study of the ‘Merwe-Vierhaven’ area (MW4 in the Rotterdam city port in the Netherlands. In order to optimize the energy balance of this urban renewal area, it is found to be impossible to do this by tuning the energy consumption. It is more effective to change the energy mix and related infrastructures. However, the problem in existing urban areas is that often these areas are restricted to a few energy sources due to lack of available space for integration. Besides this, energy consumption in most cases is relatively concentrated in (existing urban areas. This limits the potential of sustainable urban regeneration based on decentralized systems, because there is no balanced choice regarding the energy mix based on renewables and system optimization. Possible solutions to obtain a balanced energy profile can come from either the choice to not provide all energy locally, or by adding different types of storage devices to the systems. The use of energy balance based on renewables as a

    Full Text Available The much-talked about issues such as the rising of heavy crime cases, problems in solid waste management, air and water pollution as well as traffic congestion detering the quality of life among urban community members. Urgent and proactive measure is highly desireable in order to preserve and maintain the integral parts of urban’s higher quality of life. All parties should take part in ongoing efforts to achieve sustainable development through various means. Local Agenda 21 (LA21 serves as one of the efforts in achieveing the ultimate goal of sustainable development through better collaboration and cooperation among stakeholders including local government, non-governmental organisations and the community at large. The core principle of the LA21 program lies in the spirit of cooperation among community members, local authorities and the private sectors. This could be achieved through various activities including from the beginning such as through a comprehensive planning for the local area to achieve the sustainable development. Community members should be involved in brainstorming of the ideas and expressing their views so that authorities would be able to identify the real and arising issues in the community. Through this way a sustainable town and municipal planning could be developed and initiated. This paper discusses the importance of urbancommunity participation in achieving sustainable development as practicedthrough LA21 in Seberang Perai Municipal Council, Penang.

    Phenology is believed to be a suitable bio-indicator to track climate change. Based on the strong statistical association between phenology and temperature phenological observations provide an inexpensive means for the temporal and spatial analysis of the urban heat island. However, other environmental factors might also weaken this relationship. In addition, the investigation of urban phenology allows an estimation of future phenology from current information since cities with their amplified temperatures may serve as a proxy for future conditions. Nevertheless, the design of spatial compared to long-term studies might be influenced by different factors which should be taken into consideration when interpreting results from a specific study. In general, plants located in urban areas tend to flush and bloom earlier than in the countryside. What are the consequences of these urban–rural differences? This review will document existing findings on urban phenology and will highlight areas in which further research is needed. - Highlights: • Urban phenology can be used for the estimation of the urban heat island effect. • Confounding factors weaken the phenology–temperature relationship. • Urban phenology is useful as a proxy for climate change impacts on phenology. • Differences in the study design hinder the generalisation of one specific method. • Urban–rural variations in phenology affect vegetation, meteorology, human health. - Studies on urban phenology can be used to detect urban heat islands and to assess climate change impacts but it still remains important to adequately link spatial and long-term data

    In the past twenty years, various sustainable urban development policies and methods had been implemented within China, such that sustainable urbanization is now more widely accepted. Some of these policies and methods have been found to be successful in improving the sustainability of cities in China. Those practices can be defined as the best practices of sustainable urbanization, which can provide useful references for future urban developments. However, few existing studies examine how to learn from these best practices. Combining the methods of content analysis and social network analysis, this paper conducts a comprehensive study on 150 best practices of sustainable urbanization in China. The methods and outcomes of the 150 best practices are identified. The research findings demonstrate the statistics of categories, methods and outcomes of the 150 best practices and the main adopted methods. The achieved outcomes in different regions of China are also presented. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2017-11-01

    Full Text Available Sustainability is crucial to the urban zones, especially related to the water management, which is vulnerable to flood occurrence. This research applies the procedure contemplated by the Soil Conservation Service (SCS to determine the generated volumes when the impervious areas can exceed the drainage capacity of existing pluvial water networks. Several computational simulations were developed for the current scenario of an existing basin in Lisbon. Using CivilStorm software from Bentley Systems (Bentley EMEA, Bentley Systems International Limited, Dublin, Ireland, it enabled the evaluation of the volumes of flood peaks and the hydraulic behavior of a small hydrographic basin in the continuation of an urbanization process, considering the modification of its superficial impervious parts and the growth of the urbanized area. Several measures are suggested to solve the limited capacity of the existing drainage system. This study analyzes the efficiency of the application of constructive measures, pondering the viability of their effectiveness, individually and combined. The option that best minimizes the effects of the urbanization is the combination of different structural measures, in particular retention ponds, storage blocks, ditches and specific drainage interventions in some parts of the network.

    Full Text Available It can be argued that sustainable urban land development depends on the long-term viability and management success of local economic development. It can be further argued that here, economic sustainability is the key. This would furthermore signify a paradigm change to long-term administrative behavior (via an institutional approach, long-term market behavior (heterodox economics approach, and human behavior in actors’ consumption and location choices (behavioral approach. This article examines two criteria within this discourse: innovativeness and social cohesion. In doing so, it proposes a framework for empirical analysis where it is suggested that western, post-socialist and low developed cases choose different strategies due to their different starting points.

    Full Text Available Solving traffic problems, rather than in a conventional manner, i.e. through the construction of infrastructure and customization requirements, began to be implemented in a different way, by applying measures to motivate users to -use passenger car less, and that more of their daily activities are reached by nonmotorized modes of movement. Sustainable urban transport plans (SUP were introduced in legislation of the EU, strategic documents that help create a better quality of life in cities. For the purposes of this study, a review of the literature related to existing plans of some major European cities was carried out, as well as small, focusing on cities of the surroundings. On this basis, the similarities and differences were ephasized in proposed measures to reach the goals of sustainable development of transportation systems. In conclusion recommendations are given on the possibility of use of experiences and applications in all the individual local communities.

    Full Text Available Parking policies and regulations are important tools in planning for the governance of urban mobility. The proper design and location of parking facilities, in fact, contributes to an efficient use of the transportation system (or it may reduce its efficiency, when these infrastructures are not properly planned. This paper discusses the role of parking as part of the policy packages for strategic planning aimed at increasing the sustainability of urban and metropolitan areas. In particular, the integration of parking strategies in a comprehensive vision for the future of a city may significantly improve the allocation of resources and the reduction of the overall environmental externalities. The role of parking in the strategic planning of cities is discussed through the analysis of several recent projects in the city of Bari (Italy. The paper discusses the way these projects are linked (or eventually not linked to broader strategies for urban mobility, and how they might be coordinated into policy packages that promote more sustainable transportation. The use of an integrated land use transportation modeling approach to simulate the long-term evolution of the urban area may significantly contribute to estimate the long-term effects of the proposed policies. This approach may successfully support the process of policy evaluation and the selection of the optimal strategies to implement.

    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

    2016-01-01

    Full Text Available Sustainable development of cities is highly connected with the pollution generated from industrial facilities and power plants. Both affect quality of air, weather, health and quality of life. The main goal of this paper is to determine the impact of selected weather parameters on the pollution from mentioned plants. From the research results, it can be concluded that sustainable urban development and welfare of citizens are dependent on causal relationship between pollution and weather. The greatest level of impact was recorded for nitric dioxide. In the case of carbon monoxide, the level of impact is the middle. The lowest level was recorded for particulate matter. The biggest impact on the carbon monoxide emission and particulate matter is that of air pressure, whereas temperature has the biggest impact on nitrogen dioxide emission. The research shows that air humidity and wind speed do not have a significant impact on the emission of pollutants from the plants. Research shows need for further studies in the field of impact of pollution from industry on urban weather and human health.

    Full Text Available Building more energy-efficient and sustainable urban areas that will both mitigate the effects of climate change and anticipate living conditions in future climate scenarios requires the development of new tools and methods that can help urban planners, architects and communities achieve this goal. In the current study, we designed a workflow that links different methodologies developed separately, to derive the energy consumption of a university school campus for the future. Three different scenarios for typical future years (2039, 2069, 2099 were run, as well as a renovation scenario (Minergie-P. We analyzed the impact of climate change on the heating and cooling demand of buildings and determined the relevance of taking into account the local climate in this particular context. The results from the simulations confirmed that in the future, there will be a constant decrease in the heating demand, while the cooling demand will substantially increase. Significantly, it was further demonstrated that when the local urban climate was taken into account, there was an even higher rise in the cooling demand, but also that a set of proposed Minergie-P renovations were not sufficient to achieve resilient buildings. We discuss the implication of this work for the simulation of building energy consumption at the neighborhood scale and the impact of future local climate on energy system design. We finally give a few perspectives regarding improved urban design and possible pathways for future urban areas.

  12. Urban development in Freiburg, Germany – sustainable and neoliberal?

    Directory of Open Access Journals (Sweden)

    Mössner, Samuel

    2015-09-01

    Full Text Available In recent years, sustainable urban development has emerged as a relevant but contested field in urban studies. A broad and diverse literature has discussed sustainable development from various perspectives. Some authors have researched urban sustainability from a technocratic perspective, looking for technical and managerial solutions. Others have shed light on the political dimension of urban sustainable development in our times of urban neoliberalization. This branch of literature focuses on the problematic relationship between market-oriented growth on the one hand and aspects of equality and justice on the other hand, which come along with the idea of sustainability. This article argues that the professionalization and new forms of urban management, as well as a shift towards urban governance and citizens’ participation have intensified consensual practices of urban regulation. Sustainable politics that have occurred in many cities around the world place emphasis on justice, tolerance and participation as the principal drivers for urban development. Empirical evidence shows, however, that these goals are subjugated to economic growth. Drawing on empirical work carried out in Freiburg, Germany – a city long hailed as a forerunner of urban sustainable development – this article promotes the opinion that the idea of ‘sustainable development’ in its current form is nothing more than an oxymoron, aimed and invented as a fuzzy concept in order to disguise the fundamentalist believe in growth that lies beyond such development.

    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 Boston Architectural College's Urban Sustainability initiative is a demonstration project as defined by the National Energy Technology Laboratory. BAC's proposed project with the U.S. Department of Energy - NETL, is a large part of that overall initiative. The BAC's Urban Sustainability Initiative is a multi-part project with several important goals and objectives that will have a significant impact on the surrounding neighborhood including: energy conservation, reduction of storm water runoff, generation of power through alternative energy sources, elimination/reduction of BAC carbon footprint, and to create a vehicle for ongoing public outreach and education. Education and outreach opportunities will serve to add to the already comprehensive Sustainability Design courses offered at BAC relative to energy savings, performance and conservation in building design. At the finish of these essential capital projects there will be technical materials created for the education of the design, sustainability, engineering, community development and historic preservation communities, to inform a new generation of environmentally-minded designers and practitioners, the city of Boston and the general public. The purpose of the initiative, through our green renovations program, is to develop our green alley projects and energy saving renovations to the BAC physical plant, to serve as a working model for energy efficient design in enclosed 19th century and 20th century urban sites and as an educational laboratory for teaching ecological and sustainable technologies to students and the public while creating jobs. The scope of our project as it relates to the BAC and the U.S. Department of Energy- NETL combined efforts includes: Task I of the project is Phase II (Green Alley). Task I encompasses various renovation activities that will demonstrate the effectiveness of permeable paving and ground water recharge systems. It will aid in the reduction of storm water

    Full Text Available On 16 March 2014, the State Council of China launched its first urbanization planning initiative dubbed “National New Urbanization Planning (2014–2020” (NNUP. NNUP put forward 20 urban agglomerations and a sustainable development approach aiming to transform traditional Chinese urbanization to sustainable new urbanization. This study quantitatively evaluates the level of sustainability of the present new urbanization process in 20 Chinese urban agglomerations and provides some positive suggestions for the achievement of sustainable new urbanization. A three-level index system which is based on six fundamental elements in a city and a Full Permutation Polygon Synthetic Indicator evaluation method are adopted. The results show that China is undergoing a new urbanization process with a low level of sustainability and there are many problems remaining from traditional urbanization processes. There exists a polarized phenomenon in the urbanization of 20 urban agglomerations. Based on their own development patterns, the 20 urban agglomerations can be divided into seven categories. Every category has its own development characteristics. The analyses also show that waste of water resources, abuse of land resources, and air pollution are three big problems that are closely linked to traditional Chinese urbanization processes. To achieve sustainable new urbanization in China, four relevant suggestions and comments have been provided.

    Urban expansion often occurs on croplands. However, there is little scientific understanding of how global patterns of future urban expansion will affect the world's cultivated areas. Here, we combine spatially explicit projections of urban expansion with datasets on global croplands and crop yields. Our results show that urban expansion will result in a 1.8-2.4% loss of global croplands by 2030, with substantial regional disparities. About 80% of global cropland loss from urban expansion will take place in Asia and Africa. In both Asia and Africa, much of the cropland that will be lost is more than twice as productive as national averages. Asia will experience the highest absolute loss in cropland, whereas African countries will experience the highest percentage loss of cropland. Globally, the croplands that are likely to be lost were responsible for 3-4% of worldwide crop production in 2000. Urban expansion is expected to take place on cropland that is 1.77 times more productive than the global average. The loss of cropland is likely to be accompanied by other sustainability risks and threatens livelihoods, with diverging characteristics for different megaurban regions. Governance of urban area expansion thus emerges as a key area for securing livelihoods in the agrarian economies of the Global South.

    Full Text Available Amidst chaotic growth of Asian cities, the expansion of urban infrastructure in the Middle East's Gulf region is arguably outpacing any other region on the planet. Yet we have a limited understanding of the types of urban form or the extent to which this rapid urbanization is giving rise to sustainable patterns of growth. We ask, what is the pace and character of urban growth in one Middle East city, Doha, Qatar. By using remotely sensed imagery from 1987 to 2013, we examined the pace, quality, and characteristics of urban growth. We further use the results to create a typology of urban growth that integrates historical and spatial dimensions for describing the qualitative aspects of growth and its implications on regional landscapes. Our results suggest that Doha is creating development patterns similar to many Western cities, and that planners may need to consider whether the emerging urban form offers opportunities for more sustainable growth in the future.

    Full Text Available According to the United Nations, our world is becoming more populated, more urban, more connected, more globalized, and more complex. With this physical and social complexity comes a need for increased coordination in negotiating our urban futures. Environmental design and planning professionals have worked for decades according to traditional institutionalized role structures. Sustainability—in considering a wider variety of stakeholders—promises not only to include more members in the typical design and construction team (e.g., sustainability consultants, community representatives, technical specialists, etc., but also to change the jurisdiction of tasks (e.g., project management, decision making, design leadership, etc. taken on by actors in traditional roles (e.g., owner, architect, contractor, etc.. This paper examines how a wider social concern for environmental and social sustainability has affected the design and construction industry. Organizational and sociological theories suggest that professions are “bound to a set of tasks by ties of jurisdiction... [P]rofessions make up an interacting system... and a profession’s success reflects as much the situations of its competitors and the system structure as it does the profession’s own efforts” (Abbott 1988: 33. Abbott also suggests that “larger social forces” affect the structuring of professional boundaries. Treating sustainability as a “larger social force,” this paper examines current understandings of professional boundaries in the planning, design, and construction of our environments. It answers questions of how professionals renegotiate roles, responsibilities, and compensation when dealing with an uncertain change in traditional processes.The qualitative data stem from three university building projects. Each project was proposed ab initio without a mandate to achieve LEED Certification, but this complex criterion was subsequently added at different phases of

    2015-11-01

    Traditional urban water supply portfolios have proven to be unsustainable under the uncertainties associated with growth and long-term climate variability. Introducing alternative water supplies such as recycled water, captured runoff, desalination, as well as demand management strategies such as conservation and efficiency measures, has been widely proposed to address the long-term sustainability of urban water resources. Collaborative efforts have the potential to achieve this goal through more efficient use of common pool resources and access to funding opportunities for supply diversification projects. However, this requires a paradigm shift towards holistic solutions that address the complexity of hydrologic, socio-economic and governance dynamics surrounding water management issues. The objective of this work is to develop a regional integrative framework for the assessment of water resource sustainability under current management practices, as well as to identify opportunities for sustainability improvement in coupled socio-hydrologic systems. We define the sustainability of a water utility as the ability to access reliable supplies to consistently satisfy current needs, make responsible use of supplies, and have the capacity to adapt to future scenarios. To compute a quantitative measure of sustainability, we develop a numerical index comprised of supply, demand, and adaptive capacity indicators, including an innovative way to account for the importance of having diverse supply sources. We demonstrate the application of this framework to the Hetch Hetchy Regional Water System in the San Francisco Bay Area of California. Our analyses demonstrate that water agencies that share common water supplies are in a good position to establish integrative regional management partnerships in order to achieve individual and collective short-term and long-term benefits.

    Full Text Available Cities are poised to absorb additional people. Their sustainability, or ability to accommodate a population increase without depleting resources or compromising future growth, depends on whether they harness the efficiency gains from urban land management. Population is often projected as a bulk national number without details about spatial distribution. We use Landsat and population data in a methodology to project and map U.S. urbanization for the year 2020 and document its spatial pattern. This methodology is important to spatially disaggregate projected population and assist land managers to monitor land use, assess infrastructure and distribute resources. We found the U.S. west coast urban areas to have the fastest population growth with relatively small land consumption resulting in future decrease in per capita land use. Except for Miami (FL, most other U.S. large urban areas, especially in the Midwest, are growing spatially faster than their population and inadvertently consuming land needed for ecosystem services. In large cities, such as New York, Chicago, Houston and Miami, land development is expected more in suburban zones than urban cores. In contrast, in Los Angeles land development within the city core is greater than in its suburbs.

    2015-08-01

    Full Text Available This study describes a new assessment model framework, termed the driving forces-pressure-state-impact-policy and pattern (DPSIP model, for environmental change efficiency in urban land development, based on urban sustainable development and the theory of economic efficiency evaluation. A spatial and measurable efficiency value is defined for environmental changes in urban land development, which provides a comprehensive evaluation index for the efficiency of urban development and its environmental impact. This type of urban interior sustainability is considered new within the context of global environmental changes. We identify nine important indicators to evaluate the relative efficiency of 233 neighborhoods in Tainan, Taiwan. The results indicate that the average environmental change efficiency is 89.44%, which shows clear spatial differentiation. The key indicators affecting the efficiency score are area, population density, location, mixed land uses, the floor area ratio, and the impervious ratio. In the future, urban design can reduce environmental impacts and enhance efficiency values.

    2016-05-01

    Full Text Available In a time of rapid climate change and environmental degradation, planning and building an ecologically sustainable environment have become imperative. In particular, urban settlements, as a densely populated built environment, are the center of attention. This study aims to build a clear and concise synthesis of sustainable urban development not only to serve as an essential reference for decision and policy makers, but also encourage more strategically organized sustainability efforts. The extensive similarities between environmental planning and a policy-making/decision-making/problem-solving process will be carefully examined to confirm the fundamental need to build a synthesis. Major global urban sustainability rankings/standards will be presented, discussed, and integrated to produce a holistic synthesis with ten themes and three dimensions. The study will assemble disparate information across time, space, and disciplines to guide and to facilitate sustainable urban development in which both environmental concerns and human wellbeing are addressed.

    In Malaysia, urban farming is viewed as a catalyst towards achieving the well-being of urban dwellers and natural environment. Urban farming is a strategy for Malaysia’s food and economic security, and as one of the foci in the agriculture transformation whereby urban dwellers are encouraged to participate in this activity. Previous study proved that urban farming can help to address social problems of food security, urban poverty and high living cost, also provides leisure and recreation among urban dwellers. Thus, this study investigates the best urban farming practices suitable for urban setting, environment and culture of urban dwellers. Data collection was done via questionnaire survey to urban farmers of a selected community garden in Subang Jaya, Selangor. Meanwhile, on-site observations were carried out on gardening activities and the gardens’ physical attributes. The study sample encompasses of 131 urban farmers of 22 community gardens in Subang Jaya. It was found that most of the community gardens practiced crops planting on the ground or soil base planting and dwellers in the lower income group with monthly low household income constitutes the majority (83.2%) of the respondents. Social and health benefits are the highest motivating factors for urban farmers. This study provides unprecedented insights on urban farming practices and motivations in a Malaysian setting.

    A joint industry approach is needed to put in place a sustainable energy system that is economically and technologically feasible. The industry sectors involved must include the renewable energy industry, energy efficiency industry and the natural gas industry. Conventional forecasts of energy futures make far less use of these industries than is economically and technically feasible. Existing forecasts make the trade off between acceptable levels of economic growth, limitation of greenhouse gases and dependence on coal and oil appear more difficult than they actually are and overlook the benefits of sustainable energy industry development. This paper outlines how national gains from carefully targeted action can exceed national losses while substantially reducing greenhouse gases and creating jobs at zero or negative costs.

    2012-07-01

    Full Text Available The impact of development on its context is considered a key issue that governs the discussion and understanding of sustainability. For the reason, that ethics of sustainability are based on developing with no or less negative impacts on the contextual environment despite its urban scale whether limited or extended. This describes types of development that increase the good impacts on the tangible and intangible aspects of the built environment. Thus, achieving sustainability is no more a choice but it is a must especially, in an environment suffering from a lot of threats and stresses that affect all aspects of life; socially, economically, environmentally and also affect the beauty and aesthetics of urban fabrics. Assessing sustainability, the applied indicators and ways of assessment are allimportant concerns for urban sustainability discourses. Especially in such sensitive interacting domains as landscape, that links nature with the built environment. Approaching these concerns has a great deal when enhancing our environment aiming at better urban life containers. This paper aims at investigating the issue of sustainable urban landscape assessment through discussing the hue of indicators, their ways of classification, the criteria of selection and stating the variety of methods in which they can be assessed. Finally, it appropriates an approach for stating and assessing urban landscape sustainability indicators, which evaluates their both qualitative and quantitative value upon performance scale.

  18. AUTHENTICITY, IDENTITY AND SUSTAINABILITY IN POST-WAR IRAQ: Reshaping the Urban Form of Erbil City

    2014-12-01

    Full Text Available Issues of authenticity and identity are particularly significant in cities where social and cultural change is shaping active transformation of its urban fabric and structure in the post-war condition. In search of sustainable future, Iraqi cities are stretched between the two ends of the spectrum, authentic quarters with its traditional fabric and modern districts with their global sense of living. This paper interrogates the reciprocal influences and distinct qualities and sustainable performance of both authentic and modern quarters of Erbil, the capital of the Iraqi province of Kurdistan, as factors in shaping sustainable urban forms for Iraqi cities. In doing so, the paper, firstly, seeks to highlight the urban identity as an effective factor in relation to sustainable urban form. Secondly, the city of Erbil in Iraq has been chosen as a field study, due to its regional, social, political and historical role in the region. Thirdly, the study emphasises the dynamic activities and performance of residential projects according to rational sustainable criteria. The research concludes that urban identity and the sense of place in traditional and historical places should inform design strategies in order to achieve a more sustainable urban context.

    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.

  4. Looking for Sustainable Urban Mobility through Bayesian Networks

    Directory of Open Access Journals (Sweden)

    Giovanni Fusco

    2004-11-01

    Full Text Available There is no formalised theory of sustainable urban mobility systems. Observed patterns of urban mobility are often considered unsustainable. But we don’t know what a city with sustainable mobility should look like. It is nevertheless increasingly apparent that the urban mobility system plays an important role in the achievement of the city’s wider sustainability objectives.In this paper we explore the characteristics of sustainable urban mobility systems through the technique of Bayesian networks. At the frontier between multivariate statistics and artificial intelligence, Bayesian networks provide powerful models of causal knowledge in an uncertain context. Using data on urban structure, transportation offer, mobility demand, resource consumption and environmental externalities from seventy-five world cities, we developed a systemic model of the city-transportation-environment interaction in the form of a Bayesian network. The network could then be used to infer the features of the city with sustainable mobility.The Bayesian model indicates that the city with sustainable mobility is most probably a dense city with highly efficient transit and multimodal mobility. It produces high levels of accessibility without relying on a fast road network. The achievement of sustainability objectives for urban mobility is probably compatible with all socioeconomic contexts.By measuring the distance of world cities from the inferred sustainability profile, we finally derive a geography of sustainability for mobility systems. The cities closest to the sustainability profile are in Central Europe as well as in affluent countries of the Far East. Car-dependent American cities are the farthest from the desired sustainability profile.

  5. Urban Landscape Metrics for Climate and Sustainability Assessments

    Cochran, F. V.; Brunsell, N. A.

    2014-12-01

    To test metrics for rapid identification of urban classes and sustainable urban forms, we examine the configuration of urban landscapes using satellite remote sensing data. We adopt principles from landscape ecology and urban planning to evaluate urban heterogeneity and design themes that may constitute more sustainable urban forms, including compactness (connectivity), density, mixed land uses, diversity, and greening. Using 2-D wavelet and multi-resolution analysis, landscape metrics, and satellite-derived indices of vegetation fraction and impervious surface, the spatial variability of Landsat and MODIS data from metropolitan areas of Manaus and São Paulo, Brazil are investigated. Landscape metrics for density, connectivity, and diversity, like the Shannon Diversity Index, are used to assess the diversity of urban buildings, geographic extent, and connectedness. Rapid detection of urban classes for low density, medium density, high density, and tall building district at the 1-km scale are needed for use in climate models. If the complexity of finer-scale urban characteristics can be related to the neighborhood scale both climate and sustainability assessments may be more attainable across urban areas.

    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.)

    Sustainability assessment is increasingly being viewed as an important tool to aid in the shift towards sustainable urban ecosystems. An urban ecosystem is a dynamic system and requires regular monitoring and assessment through a set of relevant indicators. An indicator is a parameter which provides information about the state of the environment by producing a quantitative value. Indicator-based sustainability assessment needs to be considered on all spatial scales to provide efficient information of urban ecosystem sustainability. The detailed data is necessary to assess environmental change in urban ecosystems at local scale and easily transfer this information to the national and global scales. This paper proposes a set of key micro-level urban ecosystem indicators for monitoring the sustainability of residential developments. The proposed indicator framework measures the sustainability performance of urban ecosystem in 3 main categories including: natural environment, built environment, and socio-economic environment which are made up of 9 sub-categories, consisting of 23 indicators. This paper also describes theoretical foundations for the selection of each indicator with reference to the literature [Turkish] Highlights: • As the impacts of environmental problems have multi-scale characteristics, sustainability assessment needs to be considered on all scales. • The detailed data is necessary to assess local environmental change in urban ecosystems to provide insights into the national and global scales. • This paper proposes a set of key micro-level urban ecosystem indicators for monitoring the sustainability of residential developments. • This paper also describes theoretical foundations for the selection of each indicator with reference to the literature.

    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.

    Global food systems will face unprecedented challenges in the coming years. They will need to meet the nutritional needs of a growing population and feed an expanding demand for proteins. This is against a backdrop of increasing environmental challenges (water resources, climate change, soil health) and the need to improve farming livelihoods. Collaborative efforts by a variety of stakeholders are needed to ensure that future generations have access to healthy and sustainable diets. Food will play an increasingly important role in the global discourse on health. These topics were explored during Nestlé's second international conference on 'Planting Seeds for the Future of Food: The Agriculture, Nutrition and Sustainability Nexus', which took place in July 2017.

    Due to fast urbanization and increasing living standards, the environmental sustainability of our global society becomes more and more questionable. In this historical review we investigate the role of resources management (RM) and urban planning (UP) and propose ways for integration in sustainable development (SD). RM follows the principle of circular causation, and we reflect on to what extent RM has been an element for urban planning. Since the existence of the first settlements, a close relationship between RM, urbanization and technological development has been present. RM followed the demand for urban resources like water, energy, and food. In history, RM has been fostered by innovation and technology developments and has driven population growth and urbanization. Recent massive resource demand, especially in relation to energy and material flows, has altered natural ecosystems and has resulted in environmental degradation. UP has developed separately in response to different questions. UP followed the demand for improved living conditions, often associated to safety, good manufacturing and trading conditions and appropriate sanitation and waste management. In history UP has been a developing research area, especially since the industrial era and the related strong urbanization at the end of the 18th century. UP responded to new emerging problems in urban areas and became increasingly complex. Nowadays, UP has to address many objectives that are often conflicting, including, the urban sustainability. Our current urban un-sustainability is rooted in massive resource consumption and waste production beyond natural limits, and the absence of flows from waste to resources. Therefore, sustainable urban development requires integration of RM into UP. We propose new ways to this integration. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Urban planning solutions and decisions have large-scale significance for ecological sustainability (eco-efficiency) the consumption of energy and other natural resources, the production of greenhouse gas and other emissions and the costs caused by urban form. Climate change brings new and growing challenges for urban planning. The EcoBalance model was developed to assess the sustainability of urban form and has been applied at various planning levels: regional plans, local master plans and detailed plans. The EcoBalance model estimates the total consumption of energy and other natural resources, the production of emissions and wastes and the costs caused directly and indirectly by urban form on a life cycle basis. The results of the case studies provide information about the ecological impacts of various solutions in urban development. (orig.)

    Full Text Available Cities are the geographic nodes around which people gather for their livelihood activities. Various factors like resources, technology, education, medical innovations and environmental developments have shaped modern cities. However, with rapid urbanization and population growth, many cities are facing the problems of degradation, pollution, diseases and a poor quality of life. The major challenges before the urban growth centers have necessitated the formation of smart cities. Sustainable future of a city lies in the development of transport, infrastructure, environment, energy, ICT and people with a sustainability approach. The Government of India has launched a scheme to create hundred smart cities across the country, among which the National Capital of Delhi is a frontrunner. This paper attempts to study the existing infrastructure and facilities in Delhi in order to assess its readiness to be a smart city. It also attempts to analyze the citizens’ perception about Delhi as a smart city through a primary survey. Although there are limitations in the current scenario of economic and environmental performances and people’s perceptions, Delhi makes a strong case for becoming a smart city.

    Sustainable transport is an urging issue on a few accounts: The transport sector was responsible for 23% global CO{sub 2} emission in 2007. It also has a number of other effects like air and noise pollution, land use etc. These effects are especially relevant in cities, where already half of the world's population is living today. With a growing world population and ongoing urbanisation the number and share of city dwellers will rise considerably in the next decades. Thus, sustainability in urban transport becomes increasingly important. This report first provides a short overview of the most important data behind the sustainability problems in urban transport. Then the question is addressed, what sustainable mobility is and where the main obstacles are on the path to more sustainability. The central part of the study deals with the most important policies and instruments enhancing sustainable (urban) mobility. The main feature of each section within that part of the study is the combination of theoretical background information and arguments with case studies from developing and transition countries. Accordingly, the reader gets an idea of the vast range of available instruments in order to promote sustainable mobility. But it is also shown that it is not only necessary but also possible to introduce or enhance sustainable urban transport regardless of the income position of the specific region, country or city. Besides, success factors for different instruments are identified, thereby deriving promising routes for countries or a group of countries according to their state of economic development. (orig.)

    Full Text Available Urban parks and green spaces support a wide array of species and play an important role in long-term sustainability. This study analyzed the needs and attitudes of citizens towards urban parks and green spaces in order to provide information for setting the future direction of urban sustainability to maximize quality of life. A questionnaire survey was conducted to analyze the general characteristics of respondents and their awareness of parks and spaces. First, the results indicate that the main purpose of visiting parks was relaxation and walking. Second, the type of parks visited most frequently by the respondents was pocket parks around home. Third, the main reason for going to the frequently visited parks was “close to home”. Fourth, the major reason for visiting parks infrequently was “improper park management”. Fifth, the desired types of urban parks were relaxation parks close to natural rivers. Sixth, citizens wanted to participate in the expansion projects of parks and green spaces through non-profit civic organizations or volunteer activities. Further research with a comparative analysis among different cities will be necessary to generalize Korean attitudes to urban parks and green spaces for urban sustainability.

    Directory of Open Access Journals (Sweden)

    Dorina Pojani

    2015-06-01

    Full Text Available Megacities have frequently received a disproportionate amount of attention over other sizes of cities in recent discourse on urban sustainability. In this article, the authors argue that a focus on smaller and medium-sized cities is crucial to achieving substantial progress towards more sustainable urban development, not only because they are home to at least a quarter of the world’s population but because they also offer great potential for sustainable transformations. In principle, their size allows for flexibility in terms of urban expansion, adoption of “green” travel modes, and environmental protection. At the same time, smaller and medium-sized cities often have fewer resources to implement new transport measures and can be more vulnerable to fluctuations in the world economy. This article critically reviews the potential role and impact of nine commonly considered options for sustainable urban transport in cities in developing countries: (1 road infrastructure; (2 rail-based public transport; (3 road-based public transport; (4 support for non-motorized travel modes; (5 technological solutions; (6 awareness-raising campaigns; (7 pricing mechanisms; (8 vehicle access restrictions; and (9 control of land-uses. Drawing on international research and examples of policies to reduce the environmental impacts of transport in urban areas, this article identifies some key lessons for sustainable urban transport in smaller and medium-sized cities in developing countries. These lessons are certainly not always identical to those for megacities in the global south.

    Full Text Available Urban planning includes land use management and environmental change. It makes arrangement for community facilities and services. Since, sustainable development has been included as a vital end product of all planning goals it also provides for balanced use of land, housing and transportation and better quality of life. Present urban planning in Pakistan is not ensuring sustainable development in Pakistan. This is tested through the case study of master planning in Rawalpindi and its implementation through housing schemes in Rawalpindi, Pakistan. Large portions of provisions of master plans are not implemented. This paper explains how the urban planning will be made enabled to ensure sustainable development in Pakistan. Six numbers of housing schemes and two squatter settlements have been surveyed through questionnaires, secondary data, the opinions of the experts from related fields and site observations. Amenities and social services at far distance, very less green area, Less quantity and bad quality of water, absence of comprehensive solid waste management and sewage disposal system and nontreatment of solid waste, effluent and sewage, prevalent unhygienic conditions and air and water pollution are the existing factors effecting the sustainability. There is a need to revisit the urban planning and a comprehensive Urban and Environment Planning Law at national level and at provincial level is recommended to enable the urban planning to ensure the sustainable development in Pakistan

  10. Urban microbiomes and urban ecology: how do microbes in the built environment affect human sustainability in cities?

    Science.gov (United States)

    King, Gary M

    2014-09-01

    Humans increasingly occupy cities. Globally, about 50% of the total human population lives in urban environments, and in spite of some trends for deurbanization, the transition from rural to urban life is expected to accelerate in the future, especially in developing nations and regions. The Republic of Korea, for example, has witnessed a dramatic rise in its urban population, which now accounts for nearly 90% of all residents; the increase from about 29% in 1955 has been attributed to multiple factors, but has clearly been driven by extraordinary growth in the gross domestic product accompanying industrialization. While industrialization and urbanization have unarguably led to major improvements in quality of life indices in Korea and elsewhere, numerous serious problems have also been acknowledged, including concerns about resource availability, water quality, amplification of global warming and new threats to health. Questions about sustainability have therefore led Koreans and others to consider deurbanization as a management policy. Whether this offers any realistic prospects for a sustainable future remains to be seen. In the interim, it has become increasingly clear that built environments are no less complex than natural environments, and that they depend on a variety of internal and external connections involving microbes and the processes for which microbes are responsible. I provide here a definition of the urban microbiome, and through examples indicate its centrality to human function and wellbeing in urban systems. I also identify important knowledge gaps and unanswered questions about urban microbiomes that must be addressed to develop a robust, predictive and general understanding of urban biology and ecology that can be used to inform policy-making for sustainable systems.

    This thesis aims to study alternatives to biodiesel industry in Brazil, for 2030, taking in account the sustainability dimensions, namely economic, environmental, ecological, social, national and international politics, territorial, cultural, and technological, through the development of scenarios...... for agriculture and pasture. Thus, a simulation, using linear programming models, was made in order to verify the alternatives of feedstock to produce biodiesel. It was observed that it is possible to decentralize the market, reduce land use, and regionalize production, making better use of the availability...... to identify the driving forces to develop the scenario storylines. This proposition was tested in an in-depth interview with the biodiesel market stakeholders. Based on the findings of the two approaches, the simulations and the interviews, it was possible to obtain future alternatives, where the biodiesel...

  13. A Strategic Project Appraisal framework for ecologically sustainable urban infrastructure

    2012-01-01

    Actors in the built environment are progressively considering environmental and social issues alongside functional and economic aspects of development projects. Infrastructure projects represent major investment and construction initiatives with attendant environmental, economic and societal impacts across multiple scales. To date, while sustainability strategies and frameworks have focused on wider national aspirations and strategic objectives, they are noticeably weak in addressing micro-level integrated decision making in the built environment, particularly for infrastructure projects. The proposed approach of this paper is based on the principal that early intervention is the most cost-effective and efficient means of mitigating the environmental effects of development projects, particularly macro infrastructure developments. A strategic overview of the various project alternatives, taking account for stakeholder and expert input, could effectively reduce project impacts/risks at low cost to the project developers but provide significant benefit to wider communities, including communities of future stakeholders. This paper is the first exploratory step in developing a more systematic framework for evaluating strategic alternatives for major metropolitan infrastructure projects, based on key sustainability principles. The developed Strategic Project Appraisal (SPA) framework, grounded in the theory of Strategic Environmental Assessment (SEA), provides a means of practically appraising project impacts and alternatives in terms of quantified ecological limits; addresses the neglected topic of metropolitan infrastructure as a means of delivering sustainability outcomes in the urban context and more broadly, seeks to open a debate on the potential for SEA methodology to be more extensively applied to address sustainability challenges in the built environment. Practically applied and timed appropriately, the SPA framework can enable better decision-making and more

  14. Sustainable urban structures to challenge climate change

    2012-07-01

    Full Text Available Public spaces within the city in all their form of different types - streets, boulevards, squares, plazas, market places, green areas - are the backbone of cities. Over the centuries buildings defined the shape and quality of public spaces, valorising them in various ways. The post-modern development of urban form generated a great number of “urban spaces”, where there is no longer correspondence between architectural forms and social and political messages: shopping malls and theme parks, inner public spaces, strip developments etc. Urban sprawl accompanied by loss of agricultural/rural land and its impact on the environment are serious concerns for most cities over Europe. To strike the right balance between inner city regeneration, under-use of urban land in the old abandoned sites and the ecological benefits that accompany the new private business initiatives in suburban areas, is one of the major challenges confronting cities in Europe. The paper will analyze the complex relations between architecture and public space, in an attempt to understand how traditional urban structures, public and green spaces, squares and streets, could provide orientation for quality-oriented regeneration. Case in point is Bucharest - capital city of Romania - where aggressive intervention in the urban structure during the 1980s disrupted the fabric of the city. The investigation is oriented towards fundamental questions such as: how to secure and preserve sites that serve as initial points in upgrading processes, how to balance private investment criteria and the quality interests of the urban communities. The major aim is to provide a support for decision making in restoring the fundamental role of public urban space in shaping urban form and supporting community life.

    2014-04-01

    Full Text Available Climate change and urbanization are converging to challenge city drainage infrastructure due to their adverse impacts on precipitation extremes and the environment of urban areas. Sustainable drainage systems have gained growing public interest in recent years, as a result of its positive effects on water quality and quantity issues and additional recreational amenities perceived in the urban landscape. This paper reviews recent progress in sustainable drainage development based on literature across different disciplinary fields. After presenting the key elements and criteria of sustainable drainage design, various devices and examples of sustainable drainage systems are introduced. The state-of-the-art model approaches and decision-aid tools for assessing the sustainable alternatives are discussed and compared. The paper further explores some limitations and difficulties in the application of the innovative solutions and suggests an integrated and trans-disciplinary approach for sustainable drainage design.

  18. Urban stormwater - greywater management system for sustainable urban water management at sub-watershed level

    Science.gov (United States)

    Singh Arora, Amarpreet

    2017-11-01

    Urban water management involves urban water supply (import, treatment and distribution of water), urban wastewater management (collection, treatment and disposal of urban sewage) and urban storm water management. Declining groundwater tables, polluted and declining sources of water, water scarcity in urban areas, unsatisfactory urban water supply and sanitation situation, pollution of receiving water bodies (including the ground water), and urban floods have become the concerns and issues of sustainable urban water management. This paper proposes a model for urban stormwater and sewage management which addresses these concerns and issues of sustainable urban water management. This model proposes segregation of the sewage into black water and greywater, and urban sub-watershed level stormwater-greywater management systems. During dry weather this system will be handling only the greywater and making the latter available as reclaimed water for reuse in place of the fresh water supply. During wet weather, the system will be taking care of (collection and treatment) both the storm water and the greywater, and the excess of the treated water will be disposed off through groundwater recharging. Application of this model in the Patiala city, Punjab, INDIA for selected urban sub-watersheds has been tried. Information and background data required for the conceptualization and design of the sub-watershed level urban stormwater-greywater management system was collected and the system has been designed for one of the sub-watersheds in the Patiala city. In this paper, the model for sustainable urban water management and the design of the Sub-watershed level Urban Stormwater-Greywater Management System are described.

    Sustainable urban planning and development requires not only a fast-growing economic growth and modernity, but also social equity and environmental sustainability. Meanwhile, the global goals of sustainable development have fascinatingly set a promising urban development future by enhancing ecology based pro-poor policy program. Apparently, pro-poor development agenda has led to the notion of pro-poor tourism as part of urban development strategies on poverty alleviation. This research presents Jakarta Hidden Tour and Kampung Warna-warni as certain cases of pro-poor tourism in Indonesia. By the emergence of criticism on “pro-growth” paradigm, the critical analysis of this research focuses on the scenario of sustainable pro-poor tourism through eco-cultural based Kampung-Tour development. In accordance, debates and dilemma have been continuously arising as pros and cons regarding the ethical issues of poverty alleviation based Kampung-Tour development. Nevertheless, this paper tries to redefine Slum Kampung as potential; the writer wildly offers a concept of poverty alleviation by reinventing pro-poor tourism strategy; revitalizing slum site to eco-cultural based pro-poor tourism development as an embodiment of a sustainable urban development. By holding system thinking analysis as research method, sustainable pro-poor tourism highlights the urgency community based tourism and eco-tourism so that poverty alleviation based tourism can be tangibly perceived by the poor. In this sense, good local governance and public private partnership must be enhanced, it is due to, like any other development projects; sustainable pro-poor tourism needs a strong political commitment to alleviate urban poverty, as well as to pursue a better future of sustainable nation.

    This article presents an analysis of social sustainability in comparative theoretical context and as a challenge to the post-political interpretation of sustainability in policy practice at the urban and regional scales. Metro Vancouver provides a case study for improving our understanding of the meaning of social sustainability as a framework for social policy in that it is among the handful of cities around the world currently working to define and enact social sustainability in governance terms. Results of this participant research provide evidence that some cities are politically engaging alternative development pathways using the concept of social sustainability. For sustainable development to retain its promise as an alternative policy framework for cities, social sustainability must be at the forefront.

    After 50 plus years of working on uranium fission principles and application, it is a bit hard for me to talk about anything else - but I'll give it a try. To start, I solemnly promise not to recommend to you any new reactor design - be it small, medium, modular, or large. The Uranium-fuelled power plant will be discussed ONLY as a finished product. Note that this sketch is an optional future. Ontario will, of course, take it or leave it, in whole or in part. This paper concentrates on future potential achievements of the CANDU nuclear energy systems. In the past, this venture has produced several modular systems, ranging from small (NPD and CANDU 3), medium (CANDU 6 and 6E) and large (Bruce, Darlington, and CANDU 9). All of these projects are more Ol' less finished products, and yet the CANDU concept still has broad scope for refinement and upgrading. This paper is, however, not about nuclear technology per se, but rather it is about what nuclear energy can do, both now and in the future. What does Ontario need to do next, in the line of technology applications that can help deal with the negative aspects of human-induced climate change? What energy systems can be installed to sustain the wealth and prosperity that Ontario's citizens now enjoy? What are the opportunities and the engineering challenges ahead of us? I do wish to apologize in advance for errors and omissions, and can only hope that missed details do not detract nor completely destroy an optimistic vision. Energy engineering is my game. Economics is not my specialty though it is an integral part of every engineering project. It is likely that the topic of economics will dominate the future choice of world energy supply, whatever that choice may be. Some people claim that the decisive factor dominating decisions with respect to uranium energy will be fear. In fact many opponents of the associated technology aim to induce fear as their main guiding theme. On the contrary, it is more reasonable to expect

    Full Text Available This paper examines the planning paradigm shift related to the contested “urban renaissance” mega-project in Downtown Seoul (Korea. Similar to other global cities, over the last few decades, different mega-projects have been successfully implemented in Seoul. These projects have been considered engines for urban renewals and transformation. This paper builds on the analysis of the failure and re-framing planning strategy for the Green Corridor (GC mega-project, part of the “Urban Renaissance Master Plan for Downtown Seoul”. The GC case reveals various critical insights for urban sustainability: (i the current mega-projects’ sustainability fallacy, related to top-down, technocratic densification, and greening practices; and (ii the untapped potential of Asian traditional and irregular small scale urban patterns, and their related socio-cultural value in addressing the renaissance of the long term urban sustainability. In particular, the discussed research findings point out that urban renaissance enabling sustainability principles requires integrated, small scale, incremental, and adaptive (stepwise urban planning and design processes that go well beyond general strategies following the so-called “green growth” paradigm.

    Full Text Available There is a growing interest among national governments and international agencies in the contribution of urban centres to sustainable development. The paper outlines the new global agendas to guide this: the Sustainable Development Goals, the Paris Agreement and the New Urban Agenda. It then sets out the key challenges and opportunities facing urban governments across the Commonwealth in implementing these agendas and achieving inclusive, safe, resilient and sustainable cities. This is hampered by significant infrastructure deficits (especially in provision for water and sanitation and a lack of funding. After outlining the commitments agreed by national governments in these global agendas, the paper discusses the vital role in meeting these of city leadership, financing and investment, urban planning and local economic development. Whilst it is good to see recognition of the importance of cities to national economies, economic success in any city does not automatically contribute to a healthier city, a more inclusive city or a sustainable city. This needs capable and accountable urban governments working closely with local civil society, and the redirection of public funds and development assistance to support them.

    2017-03-01

    Urban water systems (UWSs) are challenged by the sustainability perspective. Certain limitations of the sustainability of centralized UWSs and decentralized household level wastewater treatments can be overcome by managing UWSs at an intermediate scale, referred to as small to medium sized UWSs (SMUWSs). SMUWSs are different from large UWSs, mainly in terms of smaller infrastructure, data limitation, smaller service area, and institutional limitations. Moreover, sustainability assessment systems to evaluate the sustainability of an entire UWS are very limited and confined only to large UWSs. This research addressed the gap and has developed a set of 38 applied sustainability performance indicators (SPIs) by using fuzzy-Elimination and Choice Translating Reality (ELECTRE) I outranking method to assess the sustainability of SMUWSs. The developed set of SPIs can be applied to existing and new SMUWSs and also provides a flexibility to include additional SPIs in the future based on the same selection criteria.

    2016-06-01

    Full Text Available A literature review indicates that there is an increasing number of Land Use/Transport Interaction (LUTI models being used in policy analysis and support of urban land use, transport and environmental planning. In this context, LUTI models are considered to be useful for the development of scenarios during the preparatory stage of Sustainable Urban Mobility Plans (SUMPs. A SUMP can be defined as a strategic planning framework, proposed by the European Commission, for planning and design of an urban multimodal transport system, which combines multi-disciplinary policy analysis and decision making. The objective of a SUMP is to achieve sustainable urban mobility, i.e. accessibility for all, safety and security, reduction in emissions and energy consumption, efficient and cost-effective transport and an improvement in the urban environment. Based on the overall conceptual and methodological framework of LUTI models (Geurs and van Wee 2004, the scope of the proposed research is to fully integrate a LUTI model into a contemporary transport planning framework and, more specifically, into the SUMP structure. This paper focuses on the configuration of the integration pattern, according to which a LUTI model may evolve and interact with the planning process throughout the eleven elements of the SUMP, as well as the evaluation of the benefits and drawbacks from the implementation of the proposed pattern for the enhancement of SUMP and overall promotion of sustainable urban planning.

    Urban Transport is an important sector to accomplish the goal of sustainable development in Pakistan. This is important because of the high growth of the transport sector's energy consumption, road crashes and greenhouse gas emissions. This becomes significant in the Pakistani cities where motor vehicle fleet is growing at two to three times the rate of population. Transport Policies has resulted high growth of urban road traffic, increasing air and noise pollution throughout the country. This situation raised the question how to achieve sustainable urban transport in the mega cities of Pakistan? Development of sustainable urban transport indicators will provide an opportunity to analyze current transport policies to assess Pakistan progress towards or away from sustainability. Medium Term Development Framework (2005-10) has selected to analyze against establish sustainable urban transport indicators for Pakistan. On the basis of analysis, it has found that MWF has tried to address transport problem in a piecemeal manner, rather than adopting a holistic approach. Implementing MTDF policies on transport is not fully matched with a long term commitment to achieving sustainable development in Pakistan. (author)

    Sustainable transport is an urging issue on a few accounts: The transport sector was responsible for 23% global CO{sub 2} emission in 2007. It also has a number of other effects like air and noise pollution, land use etc. These effects are especially relevant in cities, where already half of the world's population is living today. With a growing world population and ongoing urbanisation the number and share of city dwellers will rise considerably in the next decades. Thus, sustainability in urban transport becomes increasingly important. This report first provides a short overview of the most important data behind the sustainability problems in urban transport. Then the question is addressed, what sustainable mobility is and where the main obstacles are on the path to more sustainability. The central part of the study deals with the most important policies and instruments enhancing sustainable (urban) mobility. The main feature of each section within that part of the study is the combination of theoretical background information and arguments with case studies from developing and transition countries. Accordingly, the reader gets an idea of the vast range of available instruments in order to promote sustainable mobility. But it is also shown that it is not only necessary but also possible to introduce or enhance sustainable urban transport regardless of the income position of the specific region, country or city. Besides, success factors for different instruments are identified, thereby deriving promising routes for countries or a group of countries according to their state of economic development. (orig.)

    Urban development nowadays, not only in Poland but also throughout the world, is an important issue for planners, municipal authorities and residents themselves. New structures generated in spontaneous urban and suburban areas constitute randomly scattered seeds of excessive residential and little commercial functions which therein appear more often as temporary or even ephemeral installations emerging where it is temporarily needed. The more important special services are provided rarely. Correct thinking about creating cities involves simultaneous thinking on providing different basic functions required by local communities, but at the same time recognizing temporal fluctuations and distinction on what kind of amenities have to be provided in particular area permanently (such as e.g. medical care, preventive services and schools), with others retaining its mobile, non-formal character. An even greater problem is a restoration of urban structures in the areas affected by natural disasters or leftover areas being previously war zones, where similar deficits have significantly higher impact being potential cause of higher toll in human lives, if no functional nodes providing essential functions survived. The Ariadne’s Thread is a research project which proposes infrastructure and nodes for such urban areas. It develops new framework for creating nodes not only aimed at fulfilling basic needs of people but achieving social integration and build stability for fragile communities. The aim of the paper is to describe the process of identification of a relationship between needs of the inhabitants and both programmatic and ideological approach to Ariadne’s Thread (AT) node giving ultimately its architectural interpretation. The paper will introduce the process of recognition of local needs, the interpretive and/or participatory mechanisms of establishing the node as a response to this recognition containing conceptual programming, socio-cultural programming, and

    Full Text Available The design, development, and operation of current and future urban water infrastructure in many parts of the world increasingly rely on and apply the principles of sustainable development. However, this approach suffers from a lack of the necessary knowledge, skills, and practice of how sustainable development can be attained and promoted in a given city. This paper presents the framework of an integrated systems approach analysis that deals with the abovementioned issues. The “Water and Urban Initiative” project, which was implemented by the United Nations University’s Institute for the Advanced Study of Sustainability, focused on urban water and wastewater systems, floods, and their related health risk assessment, and the economics of water quality improvements. A team of researchers has investigated issues confronting cities in the developing countries of Southeast Asia, in relation to sustainable urban water management in the face of such ongoing changes as rapid population growth, economic development, and climate change; they have also run future scenarios and proposed policy recommendations for decision-makers in selected countries in Southeast Asia. The results, lessons, and practical recommendations of this project could contribute to the ongoing policy debates and decision-making processes in these countries.

    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.

    2018-03-01

    The article presents the results of a complex experimental-analytical research of residential development energy parameters - survey of construction sites and determination of calculated energy parameters (resistance to heat transfer) considering their technical condition. The authors suggest a methodology for assessing residential development energy parameters on the basis of construction project's structural analysis with the use of advanced intelligent collection systems, processing (self-organizing maps - SOM) and data visualization (geo-informational systems - GIS). SOM clustering permitted to divide the housing stock (on the example of Arkhangelsk city) into groups with similar technical-operational and energy parameters. It is also possible to measure energy parameters of construction project of each cluster by comparing them with reference (normative) measures and also with each other. The authors propose mechanisms for increasing the area's energy stability level by implementing a set of reproduction activities for residential development of various groups. The analysis showed that modern multilevel and high-rise construction buildings have the least heat losses. At present, however, ow-rise wood buildings is the dominant styles of buildings of Arkhangelsk city. Data visualisation on the created heat map showed that such housing stock covers the largest urban area. The development strategies for depressed areas is in a high-rise building, which show the economic, social and environmental benefits of upward growth of the city. An urban regeneration programme for severely rundown urban housing estates is in a high-rise construction building, which show the economic, social and environmental benefits of upward growth of the city.

    2016-12-01

    Full Text Available Cities are perhaps one of the most challenging and yet enabling arenas for sustainable development goals. The Sustainable Development Goals (SDGs emphasize the need to monitor each goal through objective targets and indicators based on common denominators in the ability of countries to collect and maintain relevant standardized data. While this approach is aimed at harmonizing the SDGs at the national level, it presents unique challenges and opportunities for the development of innovative urban-level metrics through big data innovations. In this article, we make the case for advancing more innovative targets and indicators relevant to the SDGs through the emergence of urban big data. We believe that urban policy-makers are faced with unique opportunities to develop, experiment, and advance big data practices relevant to sustainable development. This can be achieved by situating the application of big data innovations through developing mayoral institutions for the governance of urban big data, advancing the culture and common skill sets for applying urban big data, and investing in specialized research and education programs.

    2017-10-01

    Landfill is one of the most common, widely used waste management technique in Malaysia. The ever increasing of solid waste has made the role of landfill become prominent despite the negative impacts that caused by the landfill is unavoidable. The public and government regulations are getting more aware with the negative impacts that could be brought by the landfill towards the community. It led to the cultural shift to integrate the concept of sustainability into the planning of siting a landfill in an urban area. However, current urban planning tends to emphasize more on the environmental aspect instead of social and economic aspects. This is due to the existing planning guidelines and stakeholder’s understandings are more on the environmental aspect. This led to the needs of incorporating the concept of sustainability into the urban planning. Thus, this paper focuses on the industry stakeholders view on the negative impacts that will cause by the landfill towards the urban planning. The industry stakeholders are those who are related to the decision-making in the selection of a landfill site in the government department. The scope of the study is within the country of Malaysia. This study was conducted through the semi-structured interviews with a total of fifteen industry stakeholders to obtain their perspective on the issues of impacts of siting a landfill in the urban area. The data obtained was analysed using the software, QSR NVivo version 10. Results indicate that landfill bought significant sustainability-related impacts towards landfill siting in urban planning. The negative impacts stated by the respondents are categorized under all three sustainable aspects such as environmental, social and economic. Among the results are such as the pollution, such as the generation of leachate, the objection in siting a landfill site against by the public, and the negotiating and getting money contribution from local authorities. The results produced can be served

    2016-05-20

    To prepare for an urban influx of 2.5 billion people by 2050, it is critical to create cities that are low-carbon, resilient, and livable. Cities not only contribute to global climate change by emitting the majority of anthropogenic greenhouse gases but also are particularly vulnerable to the effects of climate change and extreme weather. We explore options for establishing sustainable energy systems by reducing energy consumption, particularly in the buildings and transportation sectors, and providing robust, decentralized, and renewable energy sources. Through technical advancements in power density, city-integrated renewable energy will be better suited to satisfy the high-energy demands of growing urban areas. Several economic, technical, behavioral, and political challenges need to be overcome for innovation to improve urban sustainability.

    The fast growing of some cities has produced important changes in the urban sectors not always following sustainability criteria. As results, most urban growth falls outside formal planning controls and many cities suffer poor urban services management, traffic, and congestion, loss of green areas, poor air quality, and noise. The main advantages of satellite-based EO products are to support the decision-making process, and the development and operation of smart services. Satellite-based urban morphology analysis can help to identify the transformation of the urban development and evolution. The pilot presented here is a demonstration in the framework of the collaboration between ESA and ADB, called EOTAP "Earth Observation for a Transforming Asia Pacific". Aim of the pilot is to exploit satellite Earth observation data for sustainable growth and help preparing a series of city development and investment plans.

    Full Text Available Urban environmental problems are of different dimensions and are mostly due to geologic, climatic and cultural factors. However, the cultural factors seems to be more pronounced in the Nigerian context because most of the identified urban environmental issues are so much associated with the way of life of the people, either as reactions to urbanization or their spatial heritage. Their effects are far reaching on efforts to attain sustainable development in the country. Since no section of the country’s urban environment is immune to environmental effects, there is urgent need to seek workable solutions by the application of planning, economic, legal, institutional and educational tools as have been suggested here.

  1. Introducing Urban Food Forestry: A Multifunctional Strategy for Enhancing Urban Sustainability

    Science.gov (United States)

    Nicholas, K. A.; Clark, K.

    2012-12-01

    We propose combining elements of urban agriculture and urban forestry into what we call "urban food forestry" (UFF), the practice of growing perennial woody food-producing species ("food trees") in cities. We used four approaches at different scales to gauge the potential of UFF to enhance urban sustainability, in the context of trends including increasing urbanization, resource demands, and climate change. First, we analyzed 37 current international initiatives based around urban food trees, finding that core activities included planting, mapping, and harvesting food trees, but that only about a quarter of initiatives engaged in more than one of these activities necessary to fully utilize the food potential of urban trees. Second, we analyzed 30 urban forestry master plans, finding that only 13% included human food security among their objectives. Third, we used Burlington, Vermont as a case study to quantify the potential caloric output of publicly accessible open space if planted with Malus domestica (the common apple) under 9 different scenarios. We found that the entire caloric deficit of the very low food security population could be met on as few as 29 hectares (representing 16% of total open space), and that 98% of the daily recommended minimum intake of fruit for the entire city's population could be met under the most ambitious planting scenario. Finally, we developed a decision-making tool for selecting potential food trees appropriate for temperate urban environments, the Climate-Food-Species Matrix. We identified a total of 70 species, 30 of which we deemed "highly suitable" for urban food forestry based on their cold hardiness, drought tolerance, and edibility. We conclude that urban food forestry provides multiple pathways for building urban sustainability through local food production, and that our framework can be used to increase the coordination between and effectiveness of a growing number of related initiatives.

  2. Sustainable Urban Agriculture in Ghana: What Governance System Works?

    Directory of Open Access Journals (Sweden)

    Eileen Bogweh Nchanji

    2017-11-01

    Full Text Available Urban farming takes advantage of its proximity to market, transport and other urban infrastructure to provide food for the city and sustain the livelihoods of urban and peri-urban dwellers. It is an agricultural activity which employs more than 50% of the local urban population with positive and negative impacts on local and national development. Urban agriculture is an informal activity not supported by law but in practice is regulated to a certain extent by state institutions, traditional rulers, farmers and national and international non-governmental organisations. Tamale’s rapid population growth, exacerbated by the unplanned development system and institutional conflicts, are factors contributing to the present bottlenecks in the urban agricultural system. In this paper, these bottlenecks are conceptualised as problems of governance. These issues will be illustrated using ethnographic data from land sales, crop-livestock competition, waste-water irrigation, and markets. I will explain how conflicts which arise from these different situations are resolved through the interactions of various governance systems. Informal governance arrangements are widespread, but neither they nor formal systems are always successful in resolving governance issues. A participatory governance does not seem possible due to actors’ divergent interests. A governance solution for this sector is not yet apparent, contributing to food and nutritional insecurity.

  3. Sustainable Urban Renewal: The Tel Aviv Dilemma

    Directory of Open Access Journals (Sweden)

    Asaf Friedman Arch

    2014-04-01

    Full Text Available The city of Tel Aviv needs extensive urban renewal projects to answer the demand for housing. The area suitable for such a project is the older southern part of Tel Aviv, made up of small parcels of land with single units. This area has undergone an extreme gentrification process, which makes assembling small parcels into large ones a very difficult task. Owners holding out for higher prices may either prevent or significantly delay socially efficient redevelopment. The only current option for the Tel Aviv Municipality that will lead to efficient land assembly for private redevelopment currently is the option of private entrepreneurship. We wish to describe a mechanism that will solve the hold-out problem and lead to efficiency in land assembly without resorting to the intervention of the government to execute eminent domain. The mechanism requires the municipality to plan the development that will best suit the city, thus allowing the valuation of the parcel to reflect its true price for the owner. If the owners are still reluctant to sell, the municipality can then tax him according to the new value of the land.

  5. Urban sustainability : complex interactions and the measurement of risk

    Directory of Open Access Journals (Sweden)

    Lidia Diappi

    1999-05-01

    Full Text Available This paper focuses on the concept of asustainable city and its theoretical implications for the urban system. Urban sustainability is based on positive interactions among three different urban sub-systems : social, economic and physical, where social well-being coexists with economic development and environmental quality. This utopian scenario doesn’t appear. Affluent economy is often associated with poverty and criminality, labour variety and urban efficiency coexist with pollution and congestion. The research subject is the analysis of local risk and opportunity conditions, based on the application of a special definition of risk elaborated and made operative with the production of a set of maps representing the multidimensional facets of spatial organisation in urban sustainability. The interactions among the economic/social and environmental systems are complex and unpredictable and present the opportunity for a new methodology of scientific investigation : the connectionistic approach, processed by Self-Reflexive Neural Networks (SRNN. These Networks are a useful instrument of investigation and analogic questioning of the Data Base. Once the SRNN has learned the structure of the weights from the DB, by querying the network with the maximization or minimization of specific groups of attributes, it is possible to read the related properties and to rank the areas. The survey scale assumed by the research is purposefully aimed at the micro-scale and concerns the Municipality of Milan which is spatially divided into 144 zones.

  6. Enhancing future resilience in urban drainage system: Green versus grey infrastructure.

    Dong, Xin; Guo, Hao; Zeng, Siyu

    2017-11-01

    In recent years, the concept transition from fail-safe to safe-to-fail makes the application of resilience analysis popular in urban drainage systems (UDSs) with various implications and quantifications. However, most existing definitions of UDSs resilience are confined to the severity of flooding, while uncertainties from climate change and urbanization are not considered. In this research, we take into account the functional variety, topological complexity, and disturbance randomness of UDSs and define a new formula of resilience based on three parts of system severity, i.e. social severity affected by urban flooding, environmental severity caused by sewer overflow, and technological severity considering the safe operation of downstream facilities. A case study in Kunming, China is designed to compare the effect of green and grey infrastructure strategies on the enhancement of system resilience together with their costs. Different system configurations with green roofs, permeable pavement and storage tanks are compared by scenario analysis with full consideration of future uncertainties induced by urbanization and climate change. The research contributes to the development of sustainability assessment of urban drainage system with consideration of the resilience of green and grey infrastructure under future change. Finding the response measures with high adaptation across a variety of future scenarios is crucial to establish sustainable urban drainage system in a long term. Copyright © 2017.

    1997-01-01

    This article reviews some issues reflected in the 1996 UN Habitat II agenda and recent research on urbanization. The themes of the 1996 Habitat conference were urban development, urban poverty, and governance, civil society, and social capital. It is expected that over 50% of total world population will live in cities in the year 2000. Cities are viewed both as engines of economic growth and centers of severe economic, environmental, and social problems. There is some disagreement about whether cities are rational economic structures or what the World Bank's urban agenda is and its relationship with macroeconomic policy. Discussions of global urban issues are criticized for their neglect of issues of equity and poverty, cultural diversity, and identity and representation. Habitat II also stressed urban sustainability. There is growing recognition that urban management involves more than the "Brown Agenda" of environmental and physical aspects of urban growth. Recent studies identify how politics and power affect people's access to basic urban services. Urban economic activity can also contribute to environmental problems. Urban growth affects the provision of health services. Although there is not a consensus on the role of cities in expanding economic and social development and the best management practices, there is sufficient evidence to indicate that urban processes are varied throughout the developing world. The links between urban and rural areas differentiate cities and expose the need to understand the role of intermediate urban areas surrounding and between larger cities. Poverty has become increasingly urbanized, but the extent of poverty is unknown. Habitat II was an unprecedented effort to engage nongovernment groups, local government staff, trade unions, and the private sector and to emphasize community participation. Networks of trust and reciprocity are key to solving poverty, inequality, and disempowerment problems.

  11. 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

    Cities are responsible for the depletion of natural resources and agricultural lands, and 70% of global CO{sub 2} emissions. There are significant risks to cities from the impacts of climate change in addition to existing vulnerabilities, primarily because of rapid urbanization. Urban design and development are generally considered as the instrument to shape the future of the city and they determine the pattern of a city's resource usage and resilience to change, from climate or otherwise. Cities are inherently dynamic and require the participation and engagement of their diverse stakeholders for the effective management of change, which enables wider stakeholder involvement and buy-in at various stages of the development process. Sustainability assessment of urban design and development is increasingly being seen as indispensable for informed decision-making. A sustainability assessment tool also acts as a driver for the uptake of sustainable pathways by recognizing excellence through their rating system and by creating a market demand for sustainable products and processes.

    Full Text Available The attention of countries either the developed or developing countries on sustainable urban transport is becoming more popular. The purpose of paper is to review the methods and the indicators used for measuring performance of sustainable urban transport. This study is based on the literature review and the case study observation and also uses the quantitative assessment. It reviews the theoretical aspects of sustainability factors at various research works and performance indicator in urban transportation. The indicators were classified into two major categories: (i assessment methods in sustainable urban transport (SUT, and (ii basic of sustainability indicators for urban transport. This study found several types of analytical techniques for measuring sustainability indicators in urban transport. It also identify five indicators as basic element to measure sustainable urban transport performance i.e. traffic congestion, traffic air pollution, traffic noise pollution, traffic accidents and land consumption for transport infrastructure.

  1. Sustainability Challenges from Climate Change and Air Conditioning Use in Urban Areas

    Directory of Open Access Journals (Sweden)

    Karin Lundgren

    2013-07-01

    Full Text Available Global climate change increases heat loads in urban areas causing health and productivity risks for millions of people. Inhabitants in tropical and subtropical urban areas are at especial risk due to high population density, already high temperatures, and temperature increases due to climate change. Air conditioning is growing rapidly, especially in South and South-East Asia due to income growth and the need to protect from high heat exposures. Studies have linked increased total hourly electricity use to outdoor temperatures and humidity; modeled future predictions when facing additional heat due to climate change, related air conditioning with increased street level heat and estimated future air conditioning use in major urban areas. However, global and localized studies linking climate variables with air conditioning alone are lacking. More research and detailed data is needed looking at the effects of increasing air conditioning use, electricity consumption, climate change and interactions with the urban heat island effect. Climate change mitigation, for example using renewable energy sources, particularly photovoltaic electricity generation, to power air conditioning, and other sustainable methods to reduce heat exposure are needed to make future urban areas more climate resilient.

    It is in cities that the negative impacts of a warming climate will be felt most strongly. The summer time comfort and well-being of the urban population will become increasingly compromised under future scenarios for climate change and urbanisation. In contrast to rural areas, where night-time relief from high daytime temperatures occurs as heat is lost to the sky, the city environment stores and traps heat and offers little respite from high temperatures. This urban heat island effect is responsible for temperature differences of up to 7 deg. C between cities and the country in the UK. We already have experience of the potential hazards of these higher temperatures. The majority of heat-related fatalities during the summer of 2003 were in urban areas. This means that the cooling of the urban environment is a high priority for urban planners and designers. Proven ways of doing this include altering the urban microclimate by modifying its heat absorption and emission, for example through urban greening, the use of high-reflectivity materials, and by increasing openness to allow cooling winds. Buildings themselves can also deliver improved comfort and higher levels of sustainability by taking advantage of exemplary facade, glazing and ventilation designs. In addition, changed behaviour by building occupants can help keep urban areas cool. The technology to reduce the future vulnerability of city dwellers to thermal discomfort is already largely in existence. But there is a need for complementary policy and planning commitments to manage its implementation, especially in existing buildings and urban areas

    Rapid urbanisation generates risks and opportunities for sustainable development. Urban policy and decision makers are challenged by the complexity of cities as social-ecological-technical systems. Consequently there is an increasing need for collaborative knowledge development that supports a whole-of-system view, and transformational change at multiple scales. Such holistic urban approaches are rare in practice. A co-design process involving researchers, practitioners and other stakeholders, has progressed such an approach in the Australian context, aiming to also contribute to international knowledge development and sharing. This process has generated three outputs: (1) a shared framework to support more systematic knowledge development and use, (2) identification of barriers that create a gap between stated urban goals and actual practice, and (3) identification of strategic focal areas to address this gap. Developing integrated strategies at broader urban scales is seen as the most pressing need. The knowledge framework adopts a systems perspective that incorporates the many urban trade-offs and synergies revealed by a systems view. Broader implications are drawn for policy and decision makers, for researchers and for a shared forward agenda.

  5. The sustainable project management: A review and future possibilities

    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.

    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.

    Jure Margeta

    2017-01-01

    Full Text Available Paper describes and analyses new and innovative concept for possible integration of solar photovoltaic (PV energy in urban water supply system (UWSS. Proposed system consists of PV generator and invertor, pump station and water reservoir. System is sized in such a manner that every his part is sized separately and after this integrated into a whole. This integration is desirable for several reasons, where the most important is the achievement of the objectives of sustainable living in urban areas i.e. achieving of sustainable urban water supply system. The biggest technological challenge associated with the use of solar, wind and other intermittent renewable energy sources RES is the realization of economically and environmentally friendly electric energy storage (EES. The paper elaborates the use of water reservoires in UWSS as EES. The proposed solution is still more expensive than the traditional and is economically acceptable today in the cases of isolated urban water system and special situations. Wider application will depend on the future trends of energy prices, construction costs of PV generators and needs for CO2 reduction by urban water infrastructure.

    Since 2000, China's urban land has expanded at a dramatic speed because of the country's rapid urbanization. The country has been experiencing unbalanced development between rural and urban areas, causing serious challenges such as agricultural security and land resources waste. Effectively evaluating the driving factors of urban land growth is essential for improving efficient land use management and sustainable urban development. This study established a principal component regression model based on eight indicators to identify their influences on urban land growth in Guangzhou. The results provided a grouping analysis of the driving factors, and found that economic growth, urban population, and transportation development are the driving forces of urban land growth of Guangzhou, while the tertiary industry has an opposite effect. The findings led to further suggestions and recommendations for urban sustainable development. Hence, local governments should design relevant policies for achieving the rational development of urban land use and strategic planning on urban sustainable development.

    2014-04-01

    This study examines the impact of future urban expansion on local near-surface temperature for Sydney (Australia) using a future climate scenario (A2). The Weather Research and Forecasting model was used to simulate the present (1990-2009) and future (2040-2059) climates of the region at 2-km spatial resolution. The standard land use of the model was replaced with a more accurate dataset that covers the Sydney area. The future simulation incorporates the projected changes in the urban area of Sydney to account for the expected urban expansion. A comparison between areas with projected land use changes and their surroundings was conducted to evaluate how urbanization and global warming will act together and to ascertain their combined effect on the local climate. The analysis of the temperature changes revealed that future urbanization will strongly affect minimum temperature, whereas little impact was detected for maximum temperature. The minimum temperature changes will be noticeable throughout the year. However, during winter and spring these differences will be particularly large and the increases could be double the increase due to global warming alone at 2050. Results indicated that the changes were mostly due to increased heat capacity of urban structures and reduced evaporation in the city environment.

A macro approach urban problems are reviewed in the context of the region (national scale. While the approach is seen as a micro city neighborhoods. This problem is closely related to the natural growth of the city population and population migration. Based on research on urban and regional development, it can be concluded: 1 the problem of urbanization of rural and small towns to large cities should be addressed; 2 urban spatial arrangements should be improved to do with increasingly limited land for development and urban development; 3 the provision of facilities and infrastructure of the city, city management, and financing of urban development, integration between government, society, and the private sector should be increased; 4 study of urban models that can accommodate all the problems of the city should be developed continuously.

    The accelerated process of urbanization that is shifting the aspects of Brazilian cities - most clearly in South East and South region states - is inherently involved with decayed levels of quality of life and little or any concern at all with the sustainability of such urban expansion. Besides the social difficulties generated from this non-planned growth - mainly in the cities' outskirts - there are many questions related to urbanization that should be reconsidered such as water, soil and air pollution; lack of water resources; floods, insufficient public transport and traffic problems; urban infra-structure and lodging privations and inadequate soil installment. This paper aims at showing how this disordered urban growth plays an important role on PETROBRAS' pipeline right of way located at the great cities urban areas, more specifically the Urban Right Of Way that cross the metropolitan region of the city of Sao Paulo. Also, it is an objective to express how such urbanization propitiate the execution of basic infra-structure in a way of integrating habitation, sanitation, environment and geotechnical sectors with the purposes of PETROBRAS of maintaining as priority the integrity of the pipelines located on the ROW as well as the integrity of these ROW themselves.

  14. Sustainable Urban Homecare Delivery with Different Means of Transport

    Directory of Open Access Journals (Sweden)

    Norina Szander

    2018-02-01

    Full Text Available Due to the increasing number of requests for homecare services, care institutions struggle to perform in urban traffic, which eventually makes travel times longer and less predictable and, therefore, leads to a declining service quality. Homecare delivery scheduling and planning tools must lead to efficient reliable routes that allow the nursing crew to make the least efforts and use the fewest institutional resources, and that consider urban sustainability goals. For the case study, a European city was selected with 58,000 people of whom 73 patients received long-term care at homes provided by 11 homecare nurses. While maximising patient satisfaction, a homecare planning algorithm considered many means of transport and minimised travel times. The study reduced the total nurses’ working hours/day by a bus and walking combination, and by comparing if nurses ride e-bikes, which respectively reduced ~35–44% of the total time that nurses spent travelling. This result is applicable to an urban environment where the public transport network is sufficient and biking is allowed on a reasonable number of roads. Better homecare management can support the efficient use of resources of health care institutions, high-quality home care and aspirations towards livable communities and sustainable development.

  15. From Information to Urban Sustainability through Innovations in Citizen Centered Transparency Mechanism

    Tiwari, A.

    2017-12-01

    Current urban information mechanisms in developing countries operate only through linear exchanges between institutions and users and therefore reinforce hierarchical relationships. Coupled with conflicting interests and perspectives of stakeholders in multilevel climate-governance and absence of grassroots information-networking for adaptation decision-making, there are therefore, existing information gaps. Central to urban sustainability is the need for citizen centered transparency (CCT) mechanisms that encompass and address the needs of the marginalized and vulnerable communities in developing countries especially. The study discloses the existing information gaps through information-needs assessment of stakeholders, and attempts to chart the desired course for responsible action within frame-work of Citizen Centered Transparency (CCT) mechanism. This involved analysis of several urban development projects for Indian metropolitans that mainly involved end-user association, and the parameters considered for breaking complexity for assessment included: a. Feedback: Ends-user feedback to improve resource consumption literacy and consequently urban behaviour and sustainable lifestyles(feedback technology, consumption displays, eco-labeling, billing, advisory services, sensor technology), and b. Administrative Traditions and Institutional Policy: Rewarding-punishing to enforce desired action(subsidies, taxation). The research thus answered: 1.Who gets the information whereas who requires it (Equity in Information Distribution)? and 2. How can information translate to responsible action in future (Transparency of Execution)? Findings suggested that, how, by using the CCT innovations it is practically possible to embed responsibilities in urban development planning, and manifesting environmental goals in municipal policies so that they bear clear potential short-term benefits, short-term costs, and have maximum compliance with the objectives of sustainable urban

    Dijk, Meine Pieter van; Zhang Mingshun

    2005-01-01

    This research in four medium-sized Chinese cities aims at measuring urban sustainability in China and focuses on three issues. First, the situation in these four cities with regard to urban sustainability is evaluated. Secondly, a number of relations between different aspects of urban sustainability is explored. Finally, it is indicated how urban managers can improve with sustainability indices as tools currently ineffective urban management practices. Although all four cities are moving towards sustainable development, the current situation shows still weak sustainability in three, and even non-sustainability in one city. The social and, in particular, the economic dimensions of urban sustainability make significant positive contributions to overall urban sustainability. However, the decline of natural resources and environmental degradation are influencing it negatively. It is therefore suggested that more priority should be assigned to urban environmental protection and management in China. The fundamental reason for environmental degradation is believed to be inefficient urban management. To implement effective urban management in China, there is an urgent need to redefine the role of local government, reform local organizational structure, enhance local participatory institutional capacity, properly distribute the urban welfare, and thus integrate economic, social and environmental objectives local strategic and action plans

    2014-12-01

    Full Text Available Sustainable water management (SWM requires allocating between competing water sector demands, and balancing the financial and social resources required to support necessary water systems. The objective of this review is to assess SWM in three sectors: urban, agricultural, and natural systems. This review explores the following questions: (1 How is SWM defined and evaluated? (2 What are the challenges associated with sustainable development in each sector? (3 What are the areas of greatest potential improvement in urban and agricultural water management systems? And (4 What role does country development status have in SWM practices? The methods for evaluating water management practices range from relatively simple indicator methods to integration of multiple models, depending on the complexity of the problem and resources of the investigators. The two key findings and recommendations for meeting SWM objectives are: (1 all forms of water must be considered usable, and reusable, water resources; and (2 increasing agricultural crop water production represents the largest opportunity for reducing total water consumption, and will be required to meet global food security needs. The level of regional development should not dictate sustainability objectives, however local infrastructure conditions and financial capabilities should inform the details of water system design and evaluation.

  18. Thermoelectricity for future sustainable energy technologies

    Directory of Open Access Journals (Sweden)

    Weidenkaff Anke

    2017-01-01

    Full Text Available Thermoelectricity is a general term for a number of effects describing the direct interconversion of heat and electricity. Thermoelectric devices are therefore promising, environmental-friendly alternatives to conventional power generators or cooling units. Since the mid-90s, research on thermoelectric properties and their applications has steadily increased. In the course of years, the development of high-temperature resistant TE materials and devices has emerged as one of the main areas of interest focusing both on basic research and practical applications. A wide range of innovative and cost-efficient material classes has been studied and their properties improved. This has also led to advances in synthesis and metrology. The paper starts out with thermoelectric history, basic effects underlying thermoelectric conversion and selected examples of application. The main part focuses on thermoelectric materials including an outline of the design rules, a review on the most common materials and the feasibility of improved future high-temperature thermoelectric converters.

    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.

    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.

    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.

    Full Text Available The aim of the research was to analyze the “design for all” concept as a key strategy for creating social sustainability. The paper attempts to answer the question: how can universal design contribute to the rational development of the city space? The author has taken part in participatory experiments. The research took into account various criteria, including the level of the city space’s adaptation to the needs and capabilities of persons with different disabilities. Analyses included qualitative studies concerning the possibilities of developing the social capital as well as creating and preserving a cohesive social structure. The analytic process allowed determining the means of raising the quality of urban planning. Finding effective and reliable analytical tools enabling the development of healthy cities which are compatible with the principles of sustainability could become both a great chance and a great challenge for urban planners. Transition from the microplanning to the macroplanning scale and following the principles of universal design at the stage of the formation of urban concepts using spatiotemporal modelling methods will lead to the creation of harmonious accessible spaces adjusted to the needs of present and future users, which will generate sustainable development and lead to the healing of a city.

    Full Text Available Assuring safer and sustainable development in seismic prone areas requires predictive measurements, i.e., hazard, vulnerability and risk assessment. This research aims to assess urban vulnerability due to seismic hazard through a risk based spatial plan. The idea is to indicate current and future potential losses due to specified hazards with given spatial and temporal units. Herein, urban vulnerability refers to the classic separation between social and physical vulnerability assessments. The research area covers six sub-districts in Bantul, Indonesia. It experienced 6.2 Mw earthquakes on May, 27th, 2006 and suffered a death toll of 5700, economic losses of up to 3.1 billion US$ and damage to nearly 80% of a 508 km2 area. The research area experienced the following regional issues: (1 seismic hazard; (2 rapid land conversion and (3 domination of low-income group. This research employs spatial multi criteria evaluations (SMCE for social vulnerability (SMCE-SV and for physical vulnerability (SMCE-PV. The research reveals that (1 SMCE-SV and SMCE-PV are empirically possible to indicate the urban vulnerability indices; and (2 integrating the urban vulnerability assessment into a spatial plan requires strategic, technical, substantial and procedural integration. In summary, without adequate knowledge and political support, any manifestation towards safer and sustainable development will remain meager and haphazard.

    Badach, Joanna; Dymnicka, Małgorzata

    2017-10-01

    Contemporary urban theory and practice in the post-industrial era is increasingly often turning towards an approach based on sustainable development. That concept bearing the traits of a paradigm has grown on the ground of broad quest for an alternative to the existing development model of the industrial civilisation. It has gained wide social acceptance and is the basis for many development and environmental programmes at the level of national and local government. It puts in a new light the socio-cultural, ecological and energy-related aspects of space as well as its value and aesthetics. A model of governing the city called ‘good urban governance’ is in a very close relation with the concept of sustainable development. It is based on the principles of inclusiveness, citizenship, accountability, processuality and effectiveness. Although this approach is not entirely novel, it stays valid and open to new challenges connected with satisfying human needs in the urban built environment on the basis of new contemporary conceptualisations such as ‘smart governance’, ‘governing the smart city’, ‘network governance’ and ‘governance networks’. The advantages of this approach based on the assumption of multidimensionality and subjectivity, matching the various and seemingly contradicting interests with a sense of responsibility for the quality of life in the urban environment are often underlined both in literature and in academic debate. The aim of this article is an attempt to present selected practices in spatial planning which employ the principles of the idea of co-governance. It will include various methodological assumptions and criteria applied in ‘good urban governance’. The intention will be to show its new research and application possibilities in countries like Poland where the idea of governance and sustainable development remains a matter of theory.

    Abstract: Urbanisation has gained momentum with globalization in India. Policy decisions to set up commercial, industrial hubs have fuelled large scale migration, added with population upsurge has contributed to the fast growing urban region that needs to be monitored in order to design sustainable urban cities. Unplanned urbanization have resulted in the growth of peri-urban region referred to as urban sprawl, are often devoid of basic amenities and infrastructure leading to large scale environmental problems that are evident. Remote sensing data acquired through space borne sensors at regular interval helps in understanding urban dynamics aided by Geoinformatics which has proved very effective in mapping and monitoring for sustainable urban planning. Cellular automata (CA) is a robust approach for the spatially explicit simulation of land-use land cover dynamics. CA uses rules, states, conditions that are vital factors in modelling urbanisation. This communication effectively introduces simulation assistances of CA with the agent based modelling supported by its fuzzy characteristics and weightages through analytical hierarchal process (AHP). This has been done considering perceived agents such as industries, natural resource etc. Respective agent's role in development of a particular regions into an urban area has been examined with weights and its influence of each of these agents based on its characteristics functions. Validation was performed obtaining a high kappa coefficient indicating the quality and the allocation performance of the model & validity of the model to predict future projections. The prediction using the proposed model was performed for 2030. Further environmental sustainability of each of these cities are explored such as water features, environment, greenhouse gas emissions, effects on human human health etc., Modeling suggests trend of various land use classes transformation with the spurt in urban expansions based on specific regions and

  12. A novel method for feasibility testing urban sustainable development policies

    Directory of Open Access Journals (Sweden)

    O’Doherty Travis

    2013-01-01

    Full Text Available Policy making to promote more sustainable development is a complex task due in part to the large number of both stakeholders and potential policies. Policy feasibility testing provides a guide to the viability and practicality of policy implementation and forms an important part of an evidence based policy making process. An extensive literature review has identified no standardized approach to feasibility testing. This paper addresses this knowledge gap by describing a novel method using Multi-Criteria Decision Analysis (MCDA for feasibility testing of policies aimed at increasing the sustainability of towns and villages in Ireland. Feasibility results are provided for 40 frequently cited policy interventions tested for 18 settlements in Ireland. Policies were selected in the arenas of transport, food, housing and urban form, energy, waste and water. Policies are feasibility tested through analysis of operational evidence from both quantitative and qualitative data sources. Following testing, policies are ranked in terms of feasibility. This research examines the effectiveness of local and national level policies and the importance of both local community involvement and central government regulation in policy success. The inter-settlement variation in feasibility testing scores prioritises policy selection and aims to reduce cherry-picking of policies to support the viewpoints of the decision maker. Although developed for an Irish urban context the methods described here may have applicability elsewhere.

    2017-01-01

    To find a more effective method for the assessment of sustainable urban transport development, the comprehensive assessment model of sustainable urban transport development was established based on the unascertained measure. On the basis of considering the factors influencing urban transport development, the comprehensive assessment indexes were selected, including urban economical development, transport demand, environment quality and energy consumption, and the assessment system of sustainable urban transport development was proposed. In view of different influencing factors of urban transport development, the index weight was calculated through the entropy weight coefficient method. Qualitative and quantitative analyses were conducted according to the actual condition. Then, the grade was obtained by using the credible degree recognition criterion from which the urban transport development level can be determined. Finally, a comprehensive assessment method for urban transport development was introduced. The application practice showed that the method can be used reasonably and effectively for the comprehensive assessment of urban transport development.

  14. Estimating current and future global urban domestic material consumption

    2018-06-01

    Urban material resource requirements are significant at the global level and these are expected to expand with future urban population growth. However, there are no global scale studies on the future material consumption of urban areas. This paper provides estimates of global urban domestic material consumption (DMC) in 2050 using three approaches based on: current gross statistics; a regression model; and a transition theoretic logistic model. All methods use UN urban population projections and assume a simple ‘business-as-usual’ scenario wherein historical aggregate trends in income and material flow continue into the future. A collation of data for 152 cities provided a year 2000 world average DMC/capita estimate, 12 tons/person/year (±22%), which we combined with UN population projections to produce a first-order estimation of urban DMC at 2050 of ~73 billion tons/year (±22%). Urban DMC/capita was found to be significantly correlated (R 2 > 0.9) to urban GDP/capita and area per person through a power law relation used to obtain a second estimate of 106 billion tons (±33%) in 2050. The inelastic exponent of the power law indicates a global tendency for relative decoupling of direct urban material consumption with increasing income. These estimates are global and influenced by the current proportion of developed-world cities in the global population of cities (and in our sample data). A third method employed a logistic model of transitions in urban DMC/capita with regional resolution. This method estimated global urban DMC to rise from approximately 40 billion tons/year in 2010 to ~90 billion tons/year in 2050 (modelled range: 66–111 billion tons/year). DMC/capita across different regions was estimated to converge from a range of 5–27 tons/person/year in the year 2000 to around 8–17 tons/person/year in 2050. The urban population does not increase proportionally during this period and thus the global average DMC/capita increases from ~12 to ~14 tons

  16. Minicities in suburbia – A model for urban sustainability?

    Directory of Open Access Journals (Sweden)

    Per Gunnar Røe

    2011-12-01

    Full Text Available In the 1970s it was argued that suburban centres in the US had developed into “minicities”, offering a wide range of possibilities for consumption, cultural events and a sense of the urban. In this article we explore to which extent this description of minicities may be valid in two cases in the suburban hinterland of Oslo. We further discuss whether the “urbanization” of these suburban centres may contribute to a more sustainable urban development, with respect to everyday travel. We conclude that the growth of these minicities may reduce car travel, either because of their excellent public transport connection to the (big city centre and other nodes in the increasingly decentralized urban region, or because they may serve as a substitute for the city centre. However, an empirical investigation of the role of minicities must be based on a deeper understanding of the social and cultural processes that guide the everyday life of today’s sub­urbanites.

    2011-10-01

    Full Text Available Purpose: The objective of the present study is to select some feasible and sustainable logistic practices in order to improve the urban freight distribution in Bilbao city. Design/methodology/approach: After a thorough literature review and a benchmarking, Analytic Hierarchy Process (AHP techniques were used in order to support the decision making processes in order to select the most interesting practices. The criteria used for this selection were based on four factors: (1 improvement of the city freight distribution, (2 implementation possibility, (3 short and medium term applicability and (4 impact on the citizens of Bilbao. Findings: The paper identifies some specific problems that must be faced during the last stage of the logistics chain, where products are usually delivered to final customers in the urban environment. Research limitations/implications: Not all good urban freight distribution practices can be applied universally to all types of towns. Therefore, it is necessary to design some practices specifically to each particular city according to the physical characteristics of the city, the companies’ motivation and the citizens’ habits. Practical implications: All the agents involved in the city freight distribution should be aware of the benefits and problems that their actions cause. Originality/value: This study was carried out from a wide perspective that included researchers, logistics operators and local authorities.

  18. An Integrated Model Based on a Hierarchical Indices System for Monitoring and Evaluating Urban Sustainability

    Directory of Open Access Journals (Sweden)

    2013-02-01

    Full Text Available Over 50% of world’s population presently resides in cities, and this number is expected to rise to ~70% by 2050. Increasing urbanization problems including population growth, urban sprawl, land use change, unemployment, and environmental degradation, have markedly impacted urban residents’ Quality of Life (QOL. Therefore, urban sustainability and its measurement have gained increasing attention from administrators, urban planners, and scientific communities throughout the world with respect to improving urban development and human well-being. The widely accepted definition of urban sustainability emphasizes the balancing development of three primary domains (urban economy, society, and environment. This article attempts to improve the aforementioned definition of urban sustainability by incorporating a human well-being dimension. Major problems identified in existing urban sustainability indicator (USI models include a weak integration of potential indicators, poor measurement and quantification, and insufficient spatial-temporal analysis. To tackle these challenges an integrated USI model based on a hierarchical indices system was established for monitoring and evaluating urban sustainability. This model can be performed by quantifying indicators using both traditional statistical approaches and advanced geomatic techniques based on satellite imagery and census data, which aims to provide a theoretical basis for a comprehensive assessment of urban sustainability from a spatial-temporal perspective.

  19. Multicriteria Spatial Decision Support Systems for Future Urban Energy Retrofitting Scenarios

    Directory of Open Access Journals (Sweden)

    Patrizia Lombardi

    2017-07-01

    Full Text Available Nowadays, there is an increasing concern about sustainable urban energy development taking into account national priorities of each city. Many cities have started to define future strategies and plans to reduce energy consumption and greenhouse gas emissions. Urban energy scenarios involve the consideration of a wide range of conflicting criteria, both socio-economic and environmental ones. Moreover, decision-makers (DMs require proper tools that can support their choices in a context of multiple stakeholders and a long-term perspective. In this context, Multicriteria Spatial Decision Support Systems (MC-SDSS are often used in order to define and analyze urban scenarios since they support the comparison of different solutions, based on a combination of multiple factors. The main problem, in relation to urban energy retrofitting scenarios, is the lack of appropriate knowledge and evaluation criteria. The latter are crucial for delivering and assessing urban energy scenarios through a MC-SDSS tool. The main goal of this paper is to analyze and test two different methods for the definition and ranking of the evaluation criteria. More specifically, the paper presents an on-going research study related to the development of a MC-SDSS tool able to identify and evaluate alternative energy urban scenarios in a long-term period perspective. This study refers to two Smart City and Communities research projects, namely: DIMMER (District Information Modeling and Management for Energy Reduction and EEB (Zero Energy Buildings in Smart Urban Districts.

    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.

    2003-01-01

    Impacts from urban stormwater runoff on receiving environments have been well documented, particularly through specific regional scientific studies. Using various local government planning and management elements, urban developments in Brisbane City are now able to address stormwater management in an increasingly holistic context. One key initiative includes facilitating Water Sensitive Urban Design (WSUD) components within an Integrated Water Management Strategy that looks at policy formation, planning strategies, design option, community marketing and acceptance, maintenance programs and finally evaluation of various WSUD approaches. These can include the use of Natural Channel Designs, grassed swales, bio-filtration systems, porous pavements and roofwater tanks in several economic combinations. By linking with the Cooperative Research Centre for Catchment Hydrology, Brisbane City Council has influenced the design of WSUD planning tools and benefited the city with academic inputs into extensive evaluation programs. As well, it has also contributed to the Cooperative Research Centre's research outcomes. These evaluation programs are increasingly providing better understanding of various stormwater quality best management practices throughout Australia. As part of the overall implementation process, active involvement by a range of stakeholders has been crucial. These stakeholders have included internal planning, development assessment and design staff, external consultants, developers, and other local and state government agencies. The latter two groups are assisting in the important task of "regionalisation" of Brisbane City Council's policies and guidelines. Implementation of WSUD initiatives and stormwater re-use strategies under Council's new "Integrated Water Management" agenda are showing some excellent results, suggesting that sustainable urban development is no longer like the search for the Holy Grail.

  3. Exploration of the Future – a Key to Sustainable Development

    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.

    2014-09-01

    Full Text Available Sustainable communities are promoted as a desirable policy goal and, in particular, local authorities are encouraged to contribute to climate change mitigation through urban planning. Furthermore, recent research takes a broad perspective on the environmental sustainability of urban areas and considers the environmental impact of all consumption. A focus group study was conducted in Finland for the purpose of examining how increased environmental awareness influences urban land use. The 32 participants of three focus groups were professionals of urban planning and environmental sustainability, at both a municipal and a state level. The main finding was that urban planning is viewed as being unable to support environmental sustainability in the broader sense. In general, the participants did not see a connection between urban structure and sustainable lifestyles and only the influence of planning on housing and daily journeys was recognised. Three main reasons for this were identified. Firstly, environmental sustainability in its broader definition is seen as too complex for urban planners to influence alone. Secondly, the dominance of short-term economic issues in decision-making and the lack of co-operation from other stakeholders to achieve environmental aims demotivate land use planners. Thirdly, the prioritisation of urban density may overrule alternative means of promoting environmental sustainability, such as the encouragement of sustainable suburban or non-urban lifestyles.

    Full Text Available Sustainable development is an objective for humanity of crucial importance to how we develop and evolve. It is also a rapidly growing discipline that is becoming increasingly applied in numerous areas, reflecting humanity's desire to ensure its activities can be sustained into the future and do not adversely affect the ecology or environment. Sustainable development is often defined based on the 1987 statement of the World Commission on Environment and Development (i.e., the Brundtland Commission. In that milestone document, sustainable development was defined as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs." But new definitions are being developed as the discipline expands and becomes more multidisciplinary and complex.

  6. A Critique of the Application of Neighborhood Sustainability Assessment Tools in Urban Regeneration

    Directory of Open Access Journals (Sweden)

    Luke Boyle

    2018-03-01

    Full Text Available Neighbourhood Sustainability Assessment Tools (NSA tools are fast becoming the principal framework for urban planners and developers for promoting urban sustainability. The majority of NSA tools promote a specific type of urban development that effectively excludes regeneration projects from the urban sustainability conversation. Given that the world’s megacities are mostly built, it is argued that it is essential that strategies for global sustainability consider that urban development is focussed internally to address existing, under-serviced communities in particular need of meaningful intervention and sustainable redevelopment frameworks. The paper uses existing knowledge on NSA tools to highlight the shortcomings of outcomes-based approaches to urban governance and builds the case that the technocratic “one-size-fits-all” approach adopted by many tools inadequately accounts for underlying institutional, social and economic arrangements that influence urban development, making them inappropriate for application in both planned and existing communities. The paper proposes that urban redevelopment strategies need to be derived from the urban realities of a particular place or context. Such strategies must be grounded in principles of urban governance, participatory action and an understanding of market dynamics. Without these collaborative procedural frameworks, urban regeneration projects will continue to inadequately transition towards more comprehensive sustainability.

    2015-03-01

    Full Text Available Sustainable urban development has been receiving growing concerns from both city managers and urban residents across the world. As a yardstick of sustainability, urban carrying capacity (UCC is an important conceptual underpinning that guides local governments in promoting sustainable urban development. However, existing studies still lack consensus not only on the theoretical aspects, but also on the methodological issues for UCC monitoring and evaluation. A knowledge gap exists, which this paper fills. This study aims to develop a practical UCC assessment framework to guide urban development towards achieving sustainability. The quantitative-based assessment framework provides a set of measurable indicators and benchmarks for city managers to conduct routine monitoring on progress toward urban sustainability, and helps identify deficient areas, which urgently need resource allocation to improve UCC. Focusing on a case study of Beijing, this study demonstrates that the framework is useful in promoting urban sustainability. This framework provides rich implications for other city prototypes in China as the nation marches into the next phase of development.

    Full Text Available Sustainable urban renovation is characterized by multiple factors (e.g., technical, socio-economic, environmental and ethical perspectives, different spatial scales and a number of administrative structures that should address the evaluation of alternative scenarios or solutions. This defines a complex decision problem that includes different stakeholders where several aspects need to be considered simultaneously. In spite of the knowledge and experiences during the recent years, there is a need of methods that lead the decision-making processes. In response, a methodology based on a KPI-driven approach for urban renovation at district level is proposed in the European Smart City project CITyFiED. The methodology is a procedure with the energy efficiency as main pillar and the local authorities as client. It is composed of seven phases that ensures an effective dialogue among all the stakeholders, aiming to understand the objectives and needs of the city to deliver a set of customized Strategies for Sustainable Urban Renovation. In order to provide guidance and quantitative criteria, three levels of indicators are integrated into the approach: City Level Indicators (L1 at city & district level, Project Level KPIs (L2, and Impact Assessment Indicators at city level (L3.

    Full Text Available Ho Chi Minh City (HCMC, the largest city in Vietnam, is steadily growing, certainly towards a mega city in the near future. Like other mega cities at the boom stage, it has to face with serious environmental matters insolvable for many years. The situation may be worse under the effects of global climate change, geological subsidence due to non-standard construction and sea level rise. The situation of HCMC can be damaged or even broken by resonant effects of unsolved environmental matters and latent impacts of climate change. This article shows the challenges to the urban sustainable development under the duo effect of urban environmental matters and climate change in Ho Chi Minh City. Opportunities and strategic directions to overcome the challenges are also analyzed and recommended.

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

    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.

    Although projected precipitation increases in East Asia due to future climate change have aroused concern, less attention has been paid by the scientific community and public to the potential long-term increase in precipitation due to rapid urbanization. A ten-year precipitation dataset was analysed for both a rapidly urbanized megacity and nearby suburban/rural stations in southern China. Rapid urbanization in the megacity was evident from satellite observations. A statistically significant, long-term, increasing trend of precipitation existed only at the megacity station (45.6mm per decade) and not at the other stations. The increase was attributed to thermal and dynamical modifications of the tropospheric boundary layer related to urbanization, which was confirmed by the results of our WRF-SLUCM simulations. The results also suggested that a long-term regional increase in precipitation, caused by greenhouse gas-induced climate change, for instance, was not evident within the study period. The urbanization-induced increase was found to be higher than the precipitation increase (18.3mm per decade) expected from future climate change. The direct climate impacts due to rapid urbanization is highlighted with strong implications for urban sustainable development and the planning of effective adaptation strategies for issues such as coastal defenses, mosquito-borne disease spread and heat stress mortality.

    Current trends in transport indicate that the system is moving away from sustainability and that major changes are necessary to make the transport system more compatible with environmental sustainability. Main problems may occur in urban transport, where not many promising solutions are expected, while the problems are severe. In view of the great number of uncertainties, we will in our paper resort to scenarios. In the paper, expert scenarios, which lead to a sustainable transport system are constructed by applying the recently developed `Spider model`. Based on a set of distinct characteristics, leading to eight axes in the spatial, institutional, economic and social-psychological field, an evaluation framework is constructed, which visualizes the driving forces that largely influence the future of the transport system. Next, expected and desired scenarios are constructed by means of opinions of Dutch transport experts - both average scenarios and scenarios of segments of the respondents - which have been investigated by means of a survey. The expected scenarios indicate that many current trends will continue, while the transport system is largely the same as the current one. The desired scenarios on the other hand, suggest the emergence and the need for a more collective system, in which also many new modes are operating. In the paper the resulting urban transport systems are also discussed. By calculating the CO2 emissions in the average expected and desired scenario, it appears that the expected scenario does not lead to a large scale reduction of those emissions; the desired scenario however, may lead to a large scale reduction of the emissions. The conclusion is that the differences in expert opinion are small and that the road towards a sustainable (urban) transport system is still far away, although the compact city concept may perhaps offer some solution. 6 figs., 2 tabs., 18 refs.

  14. General Technical Approvals for Decentralised Sustainable Urban Drainage Systems (SUDS—The Current Situation in Germany

    2015-03-01

    Full Text Available The use of decentralised, sustainable urban drainage systems (SUDS for the treatment of stormwater runoff is becoming increasingly prevalent in Germany. Decentralised SUDS can offer a viable and attractive alternative to end of pipe treatment systems for stormwater runoff from urban areas. However, there is still some uncertainty regarding the long-term performance of SUDS, and the general legislative requirements for SUDS approval and testing. Whilst the allowable pollution levels in stormwater runoff that infiltrate into ground and/or water table are regulated across Germany by the Federal Soil Protection Law, there is presently no federal law addressing the discharge requirements for surface water runoff. The lack of clear guidance can make it difficult for planners and designers to implement these innovative and sustainable stormwater treatment systems. This study clarifies the current understanding of urban stormwater treatment requirements and new technical approval guidelines for decentralised SUDS devices in Germany. The study findings should assist researchers, designers and asset managers to better anticipate and understand the performance, effective life-spans, and the planning and maintenance requirements for decentralised SUDS systems. This should help promote even greater use of these systems in the future.

  15. A brief history and the possible future of urban energy systems

    Modern cities depend on energy systems to deliver a range of services such as heating, cooling, lighting, mobility, communications, and so on. This article examines how these urban energy systems came to be, tracing the major transitions from the earliest settlements through to today's fossil-fuelled cities. The underlying theme is “increasing efficiency under constraints” with each transition marked by increasing energy efficiency in service provision, increasing per capita energy use, increasing complexity in the energy system's structure, with innovations driven by a strategic view of the overall system, and accompanied by wider changes in technology and society. In developed countries, the future of urban energy systems is likely to continue many of these trends, with increased efficiency being driven by the constraints of climate change and rising fuel prices. Both supply and demand side technologies are discussed as potential solutions to these issues, with different impacts on the urban environment and its citizens. However in developing countries, rising urban populations and access to basic energy services will drive the next transition. - Highlights: ► Urban energy system transitions in history are reviewed. ► Common features include increased per capita energy use, growing system complexity, and technological innovation. ► Future transitions will be shaped by the constraints of climate change, rising fuel prices, and urbanisation. ► Long-term sustainability depends on ability to innovate rapidly; opportunities exist on supply and demand sides.

  16. Commercial facilities in future cities and urban redevelopment

    Energy Technology Data Exchange (ETDEWEB)

    1988-07-01

    The future trends of commercial facilities were clarified by interviewing the people concerned in the commercial facilities with large floor area and relatively large energy consumption per unit area such as office building, hospital, hotel, department store, restaurant, educational facilities, sports facilities and urban redevelopment. Since an intelligent building will basically employ the office automation, it is estimated that most of the commercial buildings constructed for the future redevelopment will be intelligent buildings. Hospitals will require the system maintaining the quality of life of individual patient. It is expected that high quality hotels focusing on a touch of high class will be constructed. Department stores will aim at the daily living industry. Future restaurants will need a definite concept. Universities will have to increase new sections according to new students and change in social conditions. It is expected that high quality businesses districts and living quarters in business-centered cities will be planned for urban redevelopment. (4 figs. 3 tabs.)

    2017-05-01

    Full Text Available Adsorption is a key water pollution remediation measure used to achieve stormwater quality improvement in Sustainable urban Drainage Systems (SuDS. The level of contamination of detained sediment within SuDS assets is not well documented, with published investigations limited to specific contaminant occurrence in ponds, wetlands or infiltration devices (bioretention cells and generally focused on solute or suspended sediment. Guidance on contamination threshold levels and potential deposited sediment contamination information is not included in current UK SuDS design or maintenance guidance, primarily due to a lack of evidence and understanding. There is a need to understand possible deposited sediment contamination levels in SuDS, specifically in relation to sediment removal maintenance activities and potential impact on receiving waterways of conveyed sediment. Thus, the objective of the research presented herein was to identify what major elements and trace metals were observable in (the investigated SuDS assets detained sediment, the concentration of these major elements and trace metals and whether they met/surpassed ecotoxicity or contaminated land thresholds. The research presented here provides evidence of investigated SuDS sediment major element and trace metal levels to help inform guidance and maintenance needs, and presents a new methodology to identify the general cause (anthropocentric land use and extent of detained SuDS fine urban sediment contamination through use of a contamination matrix.

    We propose a system dynamics approach for Ecologically Sustainable Development (ESD) in urban coastal systems. A systematic analysis based on theoretical considerations, policy analysis and experts' knowledge is followed in order to define the concept of ESD. The principles underlying ESD feed the development of a System Dynamics Model (SDM) that connects the pollutant loads produced by urban systems' socioeconomic activities with the ecological condition of the coastal ecosystem that it is delineated in operational terms through key biological elements defined by the EU Water Framework Directive. The receiving waters of the Athens Metropolitan area, which bears the elements of typical high population density Mediterranean coastal city but which currently has also new dynamics induced by the ongoing financial crisis, are used as an experimental system for testing a system dynamics approach to apply the concept of ESD. Systems' thinking is employed to represent the complex relationships among the components of the system. Interconnections and dependencies that determine the potentials for achieving ESD are revealed. The proposed system dynamics analysis can facilitate decision makers to define paths of development that comply with the principles of ESD. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The Urban population of developing countries is predicted to rise from one third in 1990 to over 50% by 2025. In 1950 the world's total urban population was 734 million, of whom 448 million were living in developed countries and remaining 286 were in developing region. The total population on earth is predicted to increase by more than one billion people within the next 15 years, reaching 8.5 billion in 2030, and to increase further to 9.7 billion in 2050 and 11.2 billion by 2100. Looking at the ever increasing urbanization.In 2016, an estimated 54.5 per cent of the world's populations inhabited in urban region. By 2030, urban areas are projected to shelter 60 per cent of people worldwide and one in every three people will live in cities with at least half a million inhabitants.On the basis of these figures and other global trends, it would appear that Africa and Asia will have the highest share of world's urban growth in next 25 years, resulting consideration rise of large number of metropolitan cities and towns. Therefore issues related to urban climate change will be important for socio economic development for urban transformation through environmental sustainability.The information and communication systems plays an important role in achieving the social sustainability through environmental sustainability for urban transformation. This presentation aims to start the Global initiatives on the problem identifications in environment education for global transformation, education for socio-economic and environmental sustainability due to urbanization in 2050 to investigate problems related to social-economic risks and management issues resulting from urbanization to aid mitigation planning in globalized world and to educate scientists and local populations to form a basis for sustainable solutions in environment learning.The presentation aims to assess the potential of information and communication technology for environment education,both within different

    2016-07-01

    Full Text Available Policy makers and tourism developers must understand visitors’ mobility behavior and how they consume space and tourism resources in order to set up sustainable cultural tourism destinations. With this in mind, it should also be pointed out that the mobility patterns of tourists in urban destinations are mainly located in the city center (spatial centrality, the analysis of which enables us to define “how central” the resources (museums, monuments, etc. are and what the interactions between them are. Comprehending which factors influence visitors’ urban mobility behavior is key to understanding tourists’ consumption of space and their connections with the tourism assets of the city. Furthermore, when tourists visit a destination, they make a mental representation of the destination, constructing a mental map of it. Thus, tourists consume not only spaces but also the image of a city/destination. Moreover, the latter influences the former. The quality of surrounding architecture and urbanism plays a crucial role in enhancing the experiential value of a destination and influencing space consumption preferences. Clearly, visitors are more likely to use/consume environments that are easily navigated and mentally legible. In order to explore these patterns, a real experiment was performed based on visitor behavior in the city of Bilbao. In addition, the central places of Bilbao were determined and an analysis of the spatial interaction between cultural sites was performed, making use of a new methodology based on GPS technologies, network analysis, and surveys. This methodology is the main contribution of this work. The results suggest that (1 easy mobility (walkability, accessibility, different transport modes of the visited space facilitates the tourist experience; (2 simple and eligible mental maps of the city that are easily perceived by visitors facilitate the rapid consumption of the tourist destination; and (3 the centrality of the

    Some efforts to assess sustainability on the urban scale have been made and different tools for measuring the impact on and caused by cities have emerged. However, the sustainability concept varies from region to region, and indicators to measure it should be suitable for the context-specific conditions of the region under study. After doing a comprehensive review of the indicators included in 13 tools developed to assess urban sustainability of cities, this article proposes a new structure of indicators adapted to a Mediterranean city in Spain. The proposed structure is based on a two-level scheme that consists in 14 categories and 63 subcategories, which agglutinate urban sustainability indicators according to their purpose. This structure suggests a set of comprehensible qualitative and quantitative indicators that are easily applicable on neighbourhood or city scales. Given the similar features of Mediterranean countries in terms of environmental and socio-economic aspects, the proposed structure could be extrapolated to other countries with climatic and cultural similarities. Otherwise, the system is a useful tool in the decision-making process to help the different stakeholders involved in new urban developments and regeneration projects in existing neighbourhoods, such as developers, urban planners and public administrations. - Highlights: • Comprehensive review of 13 urban sustainability assessment tools • Proposal of a two-level structure to cluster urban sustainability indicators • Inclusion of sustainability criteria for urban planning projects and interventions.

    2017-12-01

    Full Text Available Sustainable urbanization emphasizes properly handling the relationships between people, people and society, and people and nature in the process of urban development. However, sometimes these interactions are difficult to quantify. Through an analysis of the structure and functions of the sustainable urbanization system, this paper introduced synergetic theory and constructed a sustainable urbanization synergy system (SUSS with five subsystems; demographic change, economic development, spatial structure, environmental quality, and social development; to study the synergistic development and orderly evolution trend of the sustainable urbanization composite system. Using sustainable urbanization in Henan province as an example, a mathematical quantitative model was established to measure the subsystem order degrees and the composite system synergy degree from 2006 to 2015. The results were consistent with the actual situation and indicated that over time, sustainable urbanization in Henan developed towards a more harmonious and orderly state, though the overall synergy degree was not high. It was found that the model was a sound basis for scientific judgment and effective decision-making when seeking to coordinate sustainable urbanization.

    For the first time in history, the Global population is more urban than rural and the trend is obvious at various scales. Cities do not serve just as dynamic centres of activities, jobs and consumption markets, social interactions and cultural expressions, but also carry the weight of the main environmental problems of current times and the near future. Global Warming, air and water pollution, population growth and recourse constraints, i.e. reduction of carrying capacity of the environment are among the well known ones. The overall aim of this research is to develop mitigation (at various scales) and adaptation systems, tailored to urban settlements. They should be effective at the very local as well as regional levels, assess and introduce innovative urban technologies and policies, reduce ecological footprint of cities and increase recycling efficiency. We propose the empirical method of urban sustainability assessment, that supports our hypothesis that city functioning, the changes in its population and area growth depends on the size, average and internal densities and the geographical form. The existing cities of three regions are examined: Western and Eastern Europe (incl. Russia), Latin America and China. There are fundamental urban developmental differences and also within the first region, namely between EU countries and the Eastern part of European geographical region. The cities are considered not only as some agglomerates of areas with dense population but from the ecological point of view, namely examining inflow of food and energy and outflow of waste products across the boundaries. There are major differences between the patterns of urbanisation in the studied regions, urban systems functioning and resilience. Continuous investigation of these differenced helps building regional scenarios of cities development, population allocation and pollution management for the 21st century.

  16. Managing urban stormwater for urban sustainability: Barriers and policy solutions for green infrastructure application.

    Dhakal, Krishna P; Chevalier, Lizette R

    2017-12-01

    Green infrastructure (GI) revitalizes vegetation and soil, restores hydro-ecological processes destroyed by traditional urbanization, and naturally manages stormwater on-site, offering numerous sustainability benefits. However, despite being sustainable and despite being the object of unrelenting expert advocacy for more than two decades, GI implementation remains slow. On the other hand, the practice of traditional gray infrastructure, which is known to have significant adverse impacts on the environment, is still ubiquitous in urban areas throughout the world. This relationship between knowledge and practice seems unaccountable, which has not yet received adequate attention from academia, policy makers, or research communities. We deal with this problem in this paper. The specific objective of the paper is to explore the barriers to GI, and suggest policies that can both overcome these barriers and expedite implementation. By surveying the status of implementation in 10 US cities and assessing the relevant city, state and federal policies, we identified 29 barriers and grouped them into 5 categories. The findings show that most of the barriers stem from cognitive limitations and socio-institutional arrangements. Accordingly, we suggest 33 policies, also grouped into 5 categories, which span from conducting public education and awareness programs to changing policies and governance structures.

  17. Sustainable urban housing in Kathmandu, Nepal: Proposals and evaluations

    Science.gov (United States)

    Shrestha, Vikas

    Kathmandu Valley represents one of the oldest cultural hubs in the Himalayas. The historic towns in the valley consist of densely built traditional Chowk and Bahal houses with enclosed courtyards. With exposure to the outside world since 1951, the western style single-family detached house has become an image of the modern home and a status symbol. In the context of the exploding population, the prevailing trend of these free standing houses have exacerbated urban sprawl and led to inefficient use of the limited agricultural land in the valley. Devoid of shared open spaces, the new settlements lack play areas for children, places for social gathering and a sense of community. Building materials that are not manufactured locally must be trucked from India over the mountains. So is coal for the production of brick and cement, and diesel for transportation. Minimizing the amount of imported materials and energy used by these modern houses will reduce the environmental impact and also benefit the national economy. Kathmandu enjoys clear sky conditions during winter that makes passive solar design a potential strategy to achieve thermal comfort and eliminate kerosene heaters with their harmful effects. The abundance of rainfall during monsoon season makes rainwater collection a viable supplement to the unreliable municipal water supply. This dissertation creates three new housing prototypes that address all these issues. These prototypes are modern interpretations of the vernacular Chowk and Bahal, which create communal open space by grouping rowhouses around a common courtyard. Combining vernacular wisdom with the principles of sustainable design, these prototypes reduce land consumption; reduce resource consumption; create community open space; minimize imported materials; increase energy efficiency and thermal comfort; make homes and neighborhoods self sustainable for water supply and wastewater treatment; and altogether improve the quality of life.

    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.

    Sustainable development or sustainability has been highlighted as an essential principle in urban master planning, with increasing recognition that uncontrollable urbanization may well give rise to various issues such as overexploitation of natural resources, ecosystem destruction, environmental pollution and large-scale climate change. Thus, it is deemed necessary to modify the existing urban and regional administrative system so as to cope with the challenges urban planning is being confronted with and realize the purpose of urban sustainability. This paper contributed to proposing a mechanism which helps to make urban planning with full consideration of issues with respect to sustainable development. We suggested that the integration of urban planning, SEA and ecological planning be a multi-win strategy to offset deficiency of each mentioned political tool being individually applied. We also proposed a framework where SEA and ecological planning are fully incorporated into urban planning, which forms a two-way constraint mechanism to ascertain environmental quality of urban planning, although in practice, planning and SEA processes may conditionally be unified. Moreover, as shown in the case study, the integration of the three political tools may be constrained due to slow changes in the contextual factors, in particular the political and cultural dimensions. Currently within the context of China, there may be three major elements which facilitate integration of the three political tools, which are (1) regulatory requirement of PEIA on urban planning, (2) the promotion or strong administrative support from government on eco-district building, and (3) the willingness of urban planners to collaborate with SEA experts or ecologists.

    Full Text Available Cities worldwide have been trying to achieve a sustainable urban form to handle their rapid urban growth. Many sustainable urban forms have been studied and two of them, the compact city and the eco city, were chosen in this study as urban form foundations. Based on these forms, four sustainable city criteria (compactness, compatibility, dependency, and suitability were considered as necessary functions for land use optimisation. This study presents a land use optimisation as a method for achieving a sustainable urban form. Three optimisation methods (particle swarm optimisation, genetic algorithms, and a local search method were combined into a single hybrid optimisation method for land use in Bekasi city, Indonesia. It was also used for examining Bekasi city’s land-use-plan (2010–2030 after optimising current (2015 and future land use (2030. After current land use optimisation, the score of sustainable city criteria increased significantly. Three important centres of land use (commercial, industrial, and residential were also created through clustering the results. These centres were slightly different from centres of the city plan zones. Additional land uses in 2030 were predicted using a nonlinear autoregressive neural network with external input. Three scenarios were used for allocating these additional land uses including sustainable development, government policy, and business-as-usual. Future land use allocation in 2030 found that the sustainable development scenario showed better performance compared to government policy and business-as-usual scenarios.

    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

    This paper illustrates how InSAR alone can be used to delineate potential ground fractures related to aquifer system compaction. An InSAR-derived ground fracturing map of the Toluca Valley, Mexico, is produced and validated through a field campaign. The results are of great interest to support sustainable urbanization and show that InSAR processing of open-access Synthetic Aperture Radar (SAR) data from the Sentinel-1 satellites can lead to reliable and cost-effective products directly usable by cities to help decision-making. The Toluca Valley Aquifer (TVA) sustains the water needs of two million inhabitants living within the valley, a growing industry, an intensively irrigated agricultural area, and 38% of the water needs of the megalopolis of Mexico City, located 40 km east of the valley. Ensuring water sustainability, infrastructure integrity, along with supporting the important economic and demographic growth of the region, is a major challenge for water managers and urban developers. This paper presents a long-term analysis of ground fracturing by interpreting 13 years of InSAR-derived ground displacement measurements. Small Baseline Subset (SBAS) and Persistent Scatterer Interferometry (PSI) techniques are applied over three SAR datasets totalling 93 acquisitions from Envisat, Radarsat-2, and Sentinel-1A satellites and covering the period from 2003 to 2016. From 2003 to 2016, groundwater level declines of up to 1.6 m/yr, land subsidence up to 77 mm/yr, and major infrastructure damages are observed. Groundwater level data show highly variable seasonal responses according to their connectivity to recharge areas. However, the trend of groundwater levels consistently range from -0.5 to -1.5 m/yr regardless of the well location and depth. By analysing the horizontal gradients of vertical land subsidence, we provide a potential ground fracture map to assist in future urban development planning in the Toluca Valley.

    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.

  5. Towards a sustainably certifiable futures contract for biofuels

    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

    Assessing the impact of climate change on urban landscape dynamics (ULD) is the foundation for adapting to climate change and maintaining urban landscape sustainability. This paper demonstrates an alternative future analysis by coupling a system dynamics (SD) and a cellular automata (CA) model. The potential impact of different climate change scenarios on ULD from 2009 to 2030 was simulated and evaluated in the Beijing-Tianjin-Tangshan megalopolis cluster area (BTT-MCA). The results suggested that the integrated model, which combines the advantages of the SD and CA model, has the strengths of spatial quantification and flexibility. Meanwhile, the results showed that the influence of climate change would become more severe over time. In 2030, the potential urban area affected by climate change will be 343.60-1260.66 km(2) (5.55 -20.37 % of the total urban area, projected by the no-climate-change-effect scenario). Therefore, the effects of climate change should not be neglected when designing and managing urban landscape. Copyright © 2015 Elsevier B.V. All rights reserved.

    Access to clean, affordable and reliable energy has been a cornerstone of the world's increasing prosperity and economic growth since the beginning of the industrial revolution. Our use of energy in the twenty-first century must also be sustainable. Solar and water-based energy generation, and engineering of microbes to produce biofuels are a few examples of the alternatives. This Perspective puts these opportunities into a larger context by relating them to a number of aspects in the transportation and electricity generation sectors. It also provides a snapshot of the current energy landscape and discusses several research and development opportunities and pathways that could lead to a prosperous, sustainable and secure energy future for the world.

    2003-07-01

    Sewage sludge is a serious problem due to the high treatment costs and the risks to environment and human health. Future sludge treatment will be progressively focused on an improved efficiency and environmental sustainability of the process. In this context a survey is given of most relevant sludge treatment options and separate treatment steps. Special attention is paid to those processes that are simultaneously focused on the elimination of the risks for environment and human health and on the recovery or beneficial use of the valuable compounds in the sludge such as organic carbon compounds, inorganic non-toxic substances, phosphorous and nitrogen containing compounds. Also, a brief assessment is given of the specific future technological developments regarding the various treatment steps. Furthermore, it is discussed how to assess the various pathways which can lead to the required developments. In such an assessment the technical and economic feasibility, the environmental sustainability, the societal acceptance and the implementation route are important factors. The optimal approach also strongly depends on the local and regional situation of concern and the relevant current and future boundary conditions. (author)

    Full Text Available The objective of urban mining is the safeguarding of the environment and the promotion of resource conservation through reuse, recycling, and recovery of secondary resources from waste. Urban mining maximises the resource and economic value of the waste streams generated in urban spaces and will be a significant concept in the planning and designing of sustainable cities, making the process consistent with the sustainable development goals. This review article brings out comprehensive information on urban mining as a concept and its relevance to the Indian and international context as a source of secondary raw material.

  11. The Sustainable Development Goal for Urban Sanitation: Africa's Statistical Tragedy Continues?

    Sanitation delivery in the urban areas of sub-Saharan African countries has been a chronic issue, particularly difficult to tackle. Under the Millennium Development Goals, the sanitation target in urban sub-Saharan Africa was missed by a wide margin and witnessed almost no improvement. After 2 years of review, the WHO/UNICEF Joint Monitoring Programme published a new measure of access to sanitation as a baseline for the Sustainable Development Goals. There are a number of improvements in the new measure. However, despite the improvements, the new measure continues to be characterized by an important flaw: it continues to disregard how shared toilet facilities contribute towards the SDG sanitation target. As a result, the new measure does not indicate whether progress is being made in low-income urban areas where a large number of households rely on shared sanitation; nor does it provide a goal that can be achieved in cities of the poorest countries over the measurement period. But, its most egregious failing is that it directs resources towards investments which will often fail cost/benefit tests. In sum, it is not a surprise that a Working Group recommended that the measure should be changed to include some shared facilities. Following the Working Group's recommendation would have avoided the adverse consequences of continued reliance on a key component of the methodology used for monitoring sanitation improvements under the Millennium Development Goals. The paper discusses the limitations of this methodology in the context of urban sub-Saharan Africa, where current sanitation conditions are seriously lacking, and the significant future urban population growth will add more pressure for the delivery of vital sanitation services.

    Highlights: • Review of principal regenerative braking strategies and technologies for urban rail. • Different energy storage technologies are assessed for use in urban rail. • Optimising timetables is a preferential measure to improve energy efficiency. • Energy storage systems improve efficiency and reliability of urban rail systems. • Reversible substations allow for a complete recovery of braking energy. - Abstract: In a society characterised by increasing rates of urbanisation and growing concerns about environmental issues like climate change, urban rail transport plays a key role in contributing to sustainable development. However, in order to retain its inherent advantages in terms of energy consumption per transport capacity and to address the rising costs of energy, important energy efficiency measures have to be implemented. Given that numerous and frequent stops are a significant characteristic of urban rail, recuperation of braking energy offers a great potential to reduce energy consumption in urban rail systems. This paper presents a comprehensive overview of the currently available strategies and technologies for recovery and management of braking energy in urban rail, covering timetable optimisation, on-board and wayside Energy Storage Systems (ESSs) and reversible substations. For each measure, an assessment of their main advantages and disadvantages is provided alongside a list of the most relevant scientific studies and demonstration projects. This study concludes that optimising timetables is a preferential measure to increase the benefits of regenerative braking in any urban rail system. Likewise, it has been observed that ESSs are a viable solution to reuse regenerative energy with voltage stabilisation and energy saving purposes. Electrochemical Double Layer Capacitors has been identified as the most suitable technology for ESSs in general, although high specific power batteries such as Li-ion may become a practical option for on

  13. DO POST-SOCIALIST URBAN AREAS MAINTAIN THEIR SUSTAINABLE COMPACT FORM? ROMANIAN URBAN AREAS AS CASE STUDY

    Directory of Open Access Journals (Sweden)

    Simona Raluca GRĂDINARU

    2015-12-01

    Full Text Available The compact city is regarded as an important concept in promoting sustainable development, especially within the European Union. The socialist urban planning system maintained a high compactness of the urban areas through almost exclusive predominance of the public sector in housing provision, and ideological nature of the planning strategies. After the 1990’s, the administrative decentralization allowed local authorities to adopt particular urban development strategies. However, development was directly influenced by the importance of the urban administrative centre. The aim of the paper is to determine if post-socialist urban areas maintained their compact urban form or they encountered different evolution trajectories. We determined the type of changes by calculating urban form indicators at two time moments: 1990 and 2006. Furthermore, the two-way repeated-measurement ANOVA was used to identify significant changes, and to assess the effect of the development level of the urban area on the variance of form indicators. The results show that Romanian post-socialist urban areas either shifted from the compact form, "inherited" after the collapse of socialism, to more dispersed patterns, either expanded in a compact manner. Moreover, as development level got higher, urban areas were more likely to be affected by suburbanization and periurbanization. In order to respond to these challenges, new instruments such as setting of metropolitan areas or spatial framework plans could be used. Furthermore, planning should be adapted to local circumstances and to the different development trajectories of big and mid-sized urban areas.

    The past and future of cities are inextricably linked, a linkage that can be seen clearly in the long-term impacts of urban geochemical legacies. As loci of population as well as the means of employment and industry to support these populations, cities have a long history of co-locating contaminating practices and people, sometimes with negative implications for human health. Working at the intersection between environmental processes, communities, and human health is critical to grapple with environmental legacies and to support healthy, sustainable, and growing urban populations. An emerging area of environmental health research is to understand the impacts of chronic exposures and exposure mixtures—these impacts are poorly studied, yet may pose a significant threat to population health.

  15. Urban Cultivation and Its Contributions to Sustainability: Nibbles of Food but Oodles of Social Capital

    2016-04-01

    Full Text Available The contemporary interest in urban cultivation in the global North as a component of sustainable food production warrants assessment of both its quantitative and qualitative roles. This exploratory study weighs the nutritional, ecological, and social sustainability contributions of urban agriculture by examining three cases—a community garden in the core of New York, a community farm on the edge of London, and an agricultural park on the periphery of San Francisco. Our field analysis of these sites, confirmed by generic estimates, shows very low food outputs relative to the populations of their catchment areas; the great share of urban food will continue to come from multiple foodsheds beyond urban peripheries, often far beyond. Cultivation is a more appropriate designation than agriculture for urban food growing because its sustainability benefits are more social than agronomic or ecological. A major potential benefit lies in enhancing the ecological knowledge of urbanites, including an appreciation of the role that organic food may play in promoting both sustainability and health. This study illustrates how benefits differ according to local conditions, including population density and demographics, operational scale, soil quality, and access to labor and consumers. Recognizing the real benefits, including the promotion of sustainable diets, could enable urban food growing to be developed as a component of regional foodsheds to improve the sustainability and resilience of food supply, and to further the process of public co-production of new forms of urban conviviality and wellbeing.

    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

    Full Text Available Behavioural preferences of people are changing rapidly andmaking use of all sons of technical opponunities or progress.These changes mark a general and global process usually summarizedby the term "urbanization" - rightly referring to urbansettlements. Towns and cities are parlicularly prominent manifestationsof cultural achievements of mankind. They are, atthe same time, the most imporlant means of housing, and aretools to create the values for the material base of life. Most citiesand towns do, however, cope no more with the speed of development,they lag behind and end up in structural chaos, theyfail to adapt to the future requirements. As analysis reveals, theforemost reason is inadequate location of functions resulting inunnecessary traffic. Urban settlements are inefficient, indeed,strangling themselves.To help solve this problem a model is presented here of afull-fledged city of average size.

    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.

    Large old trees are disproportionate providers of structural elements (e.g. hollows, coarse woody debris), which are crucial habitat resources for many species. The decline of large old trees in modified landscapes is of global conservation concern. Once large old trees are removed, they are difficult to replace in the short term due to typically prolonged time periods needed for trees to mature (i.e. centuries). Few studies have investigated the decline of large old trees in urban landscapes. Using a simulation model, we predicted the future availability of native hollow-bearing trees (a surrogate for large old trees) in an expanding city in southeastern Australia. In urban greenspace, we predicted that the number of hollow-bearing trees is likely to decline by 87% over 300 years under existing management practices. Under a worst case scenario, hollow-bearing trees may be completely lost within 115 years. Conversely, we predicted that the number of hollow-bearing trees will likely remain stable in semi-natural nature reserves. Sensitivity analysis revealed that the number of hollow-bearing trees perpetuated in urban greenspace over the long term is most sensitive to the: (1) maximum standing life of trees; (2) number of regenerating seedlings ha(-1); and (3) rate of hollow formation. We tested the efficacy of alternative urban management strategies and found that the only way to arrest the decline of large old trees requires a collective management strategy that ensures: (1) trees remain standing for at least 40% longer than currently tolerated lifespans; (2) the number of seedlings established is increased by at least 60%; and (3) the formation of habitat structures provided by large old trees is accelerated by at least 30% (e.g. artificial structures) to compensate for short term deficits in habitat resources. Immediate implementation of these recommendations is needed to avert long term risk to urban biodiversity.

    Full Text Available Coastal cities in China are challenged by multiple growth paths and strategies related to demands in the housing market, economic growth and eco-system protection. This paper examines the effects of conflicting strategies between economic growth and environmental protection on future urban scenarios in Ningbo, China, through logistic-regression-based cellular automata (termed LogCA modeling. The LogCA model is calibrated based on the observed urban patterns in 1990 and 2015, and applied to simulate four future scenarios in 2040, including (a the Norm-scenario, a baseline scenario that maintains the 1990–2015 growth rate; (b the GDP-scenario, a GDP-oriented growth scenario emphasizing the development in city centers and along economic corridors; (c the Slow-scenario, a slow-growth scenario considering the potential downward trend of the housing market in China; and (d the Eco-scenario, a slow-growth scenario emphasizing natural conservation and ecosystem protections. The CA parameters of the Norm- and Slow-scenarios are the same as the calibrated parameters, while the parameters of proximities to economic corridors and natural scenery sites were increased by a factor of 3 for the GDP- and Eco-scenarios, respectively. The Norm- and GDP-scenarios predicted 1950 km2 of new growth for the next 25 years, the Slow-scenario predicted 650 km2, and the Eco-scenario predicted less growth than the Slow-scenario. The locations where the newly built-up area will emerge are significantly different under the four scenarios and the Slow- and Eco-scenarios are preferable to achieve long-term sustainability. The scenarios are not only helpful for exploring sustainable urban development options in China, but also serve as a reference for adjusting the urban planning and land policies.

    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.

    2009-05-01

    Full Text Available Monetary instruments to regulate parking are often used in central areas of cities to discourage long term parking of vehicles. The availability of parking facilities, and its cost, in fact represents an important element in the decision to operate private vehicles in urban areas. The availability of instruments and tools to check the outcome of modification in parking regulations, in terms of modification of car use, successfully support planners in the determination of the best policies to decrease congestion, and regulate the use of transportation in cities. Integrated land use transportation models may successfully contribute to the assessment of such policy packages. This contribution discusses the use of the model MARS-Bari (Metropolitan Activity Relocation Simulator for the analysis of future scenarios of development of land use and transportation. MARS-Bari is a fast integrated land use transportation model, which is designed for applications in strategic planning of urban and metropolitan areas. The model was developed as a decision support tool, to help planners in the definition of sets of policies on land use and transportation, and promote equilibrated growth of the urban system (smart growth. MARS-Bari shares the basic assumptions of the Metropolitan Activity Relocation Simulator (MARS modeling system, so far successfully applied to many cities of both Europe and Asia. The structure of MARS-Bari is highly flexible on purpose, allowing multiple hypothesis tests of future scenarios and policies. MARS-Bari works at a high level of spatial aggregation, and its simulations are developed on a long-term time horizon (30-years in the current version. Two main sub-models run in MARS-Bari: they respectively simulate the development of land use, and the transportation system. Four different classes of users are distinguished in the transportation model, depending on the possible access to one or more of the five transportation modes: car

  3. A Novel Approach for Assessing the Performance of Sustainable Urbanization Based on Structural Equation Modeling: A China Case Study

    Directory of Open Access Journals (Sweden)

    Liudan Jiao

    2016-09-01

    Full Text Available The rapid urbanization process has brought problems to China, such as traffic congestion, air pollution, water pollution and resources scarcity. Sustainable urbanization is commonly appreciated as an effective way to promote the sustainable development. The proper understanding of the sustainable urbanization performance is critical to provide governments with support in making urban development strategies and policies for guiding the sustainable development. This paper utilizes the method of Structural equation modeling (SEM to establish an assessment model for measuring sustainable urbanization performance. Four unobserved endogenous variables, economic variable, social variable, environment variable and resource variable, and 21 observed endogenous variables comprise the SEM model. A case study of the 31 provinces in China demonstrates the validity of the SEM model and the analysis results indicated that the assessment model could help make more effective policies and strategies for improving urban sustainability by recognizing the statue of sustainable urbanization.

    Full Text Available City logistics is a field that attracts increasing attention of professionals and scientific community and international organizations. Research on problems of urban areas' logistics gives different results and practical solutions. City logistics flows are characterized by partiality, spatial dispersion of generators, diversity in terms of the logistics chains structure, frequency of a large number of smaller shipments, dynamism, stochasticity etc. Problems and the complexity of logistics in urban areas as well as significant decline in the quality of life in modern cities have caused the development of initiatives and concepts of city logistics which should allow the sustainable development of urban areas. The first part of this paper presents the problems of city logistics and impact of logistics activities on urban areas in terms of economic, environmental and social sustainability. The second part presents city logistics initiatives that involve the change of urban area context, in order to improve its sustainability.

    The overall objective of this research is to investigate multi-temporal, multi-scale, multi-sensor satellite data for analysis of urbanization and environmental/climate impact in China to support sustainable planning. Multi- temporal multi-scale SAR and optical data have been evaluated for urban information extraction using innovative methods and algorithms, including KTH- Pavia Urban Extractor, Pavia UEXT, and an "exclusion- inclusion" framework for urban extent extraction, and KTH-SEG, a novel object-based classification method for detailed urban land cover mapping. Various pixel- based and object-based change detection algorithms were also developed to extract urban changes. Several Chinese cities including Beijing, Shanghai and Guangzhou are selected as study areas. Spatio-temporal urbanization patterns and environmental impact at regional, metropolitan and city core were evaluated through ecosystem service, landscape metrics, spatial indices, and/or their combinations. The relationship between land surface temperature and land-cover classes was also analyzed.The urban extraction results showed that urban areas and small towns could be well extracted using multitemporal SAR data with the KTH-Pavia Urban Extractor and UEXT. The fusion of SAR data at multiple scales from multiple sensors was proven to improve urban extraction. For urban land cover mapping, the results show that the fusion of multitemporal SAR and optical data could produce detailed land cover maps with improved accuracy than that of SAR or optical data alone. Pixel-based and object-based change detection algorithms developed with the project were effective to extract urban changes. Comparing the urban land cover results from mulitemporal multisensor data, the environmental impact analysis indicates major losses for food supply, noise reduction, runoff mitigation, waste treatment and global climate regulation services through landscape structural changes in terms of decreases in service area, edge

  10. Grassroots Initiatives as Sustainability Transition Pioneers: Implications and Lessons for Urban Food Systems

    Directory of Open Access Journals (Sweden)

    Maria Gernert

    2018-03-01

    Full Text Available This review explores the current evidence on the role and success factors of grassroots initiatives in sustainability transitions, with special attention given to social innovations and the transformation of urban food systems, a field that is still rather scantly dealt with in literature compared to technological innovations in other sectors such as energy. In addition to their contributions to get the necessary transformation towards sustainable futures off the ground, the preconditions for grassroots initiatives to thrive are presented—as well as limitations regarding their possibilities and the challenges they face. Increasingly, the importance of civil society and social movements in facilitating societal transformation is recognized by both researchers and policy makers. Within their radical niches, grassroots initiatives do not have to adhere to the logics of the wider systems in which they are embedded. This allows them to experiment with diverse solutions to sustainability challenges such as local food security and sovereignty. By means of democratic, inclusive and participatory processes, they create new pathways and pilot a change of course. Nevertheless, upscaling often comes at the loss of the transformative potential of grassroots initiatives.

  11. Land use planning for sustainable development of peri-urban zones

    Directory of Open Access Journals (Sweden)

    Živanović-Miljković Jelena

    2012-01-01

    Full Text Available Taking into consideration that growth of urban population has impacts on land use and that managing urban population change is one of the most important contemporary challenges, this paper deals with the sustainable development of peri-urban zones which represent important an environment where employment opportunities are developed and resources exploited (particularly agricultural resources and environment where important recreational and leisure activities could be pursued. Within the review of current concepts and planning practices, the concepts of multifunctional agriculture and multifunctional landscapes in peri-urban zones are pointed out, as well as EU Developing Periurban Projects. The paper particularly focuses on the current situation in Serbia, where there is no specific legal basis for the planning of peri-urban areas, although there are positive examples of strategies, regulations and planning documents which treat agriculture and greenery in peri-urban zones in a sustainable manner.

  12. Evaluating climate variables, indexes and thresholds governing Arctic urban sustainability: case study of Russian permafrost regions

    Anisimov, O. A.; Kokorev, V.

    2013-12-01

    Addressing Arctic urban sustainability today forces planners to deal with the complex interplay of multiple factors, including governance and economic development, demography and migration, environmental changes and land use, changes in the ecosystems and their services, and climate change. While the latter can be seen as a factor that exacerbates the existing vulnerabilities to other stressors, changes in temperature, precipitation, snow, river and lake ice, and the hydrological regime also have direct implications for the cities in the North. Climate change leads to reduced demand for heating energy, on one hand, and heightened concerns about the fate of the infrastructure built upon thawing permafrost, on the other. Changes in snowfall are particularly important and have direct implications for the urban economy, as together with heating costs, expenses for snow removal from streets, airport runways, roofs and ventilation corridors underneath buildings erected on pile foundations on permafrost constitute the bulk of the city's maintenance budget. Many cities are located in river valleys and are prone to flooding that leads to enormous economic losses and casualties, including human deaths. The severity of the northern climate has direct implications for demographic changes governed by regional migration and labor flows. Climate could thus be viewed as an inexhaustible public resource that creates opportunities for sustainable urban development. Long-term trends show that climate as a resource is becoming more readily available in the Russian North, notwithstanding the general perception that globally climate change is one of the challenges facing humanity in the 21st century. In this study we explore the sustainability of the Arctic urban environment under changing climatic conditions. We identify key governing variables and indexes and study the thresholds beyond which changes in the governing climatic parameters have significant impact on the economy

  13. Urban sustainability through strategic planning: A case of metropolitan planning in Khulna city, Bangladesh

    Directory of Open Access Journals (Sweden)

    Md. Ashiq Ur Rahman

    2016-06-01

    Full Text Available Planning is a crucial element for any development initiative. Planning entails choice making in pursuit of stated goals e.g. improving living conditions for individuals and societies. Planning initiatives are employed within social systems that are governed by institution, and planning intervenes with and may reconfigure these institutions resulting in social change. This paper discusses how urban sustainability can be achieved through strategic action in urban development by analysing the planning process of Khulna city, Bangladesh. This paper reviews different scholarly articles to draw a conceptual framework for identifying the interface of strategic planning, components of strategic action planning and urban sustainability. Based on this conceptual framework this paper identifies the scope of achieving urban sustainability through analysing the current planning practice of Khulna city, Bangladesh. This paper identifies that though the Khulna city plan adopted the approach of strategic planning but it failed to comply with its theoretical notion to achieve the issues related to urban sustainability. Analysis reveals that in terms of social attribute that recognizes the interest of different group of people the exiting planning packages is not sustainable. Similar phenomenon have been observed in terms of recognition of gender and marginalized people in planning, equitable provision of income and employment generation, peoples’ participation in planning and polices for ensuring equitable access to infrastructure services. Therefore the existing planning package of Khulna city failed to achieve the issues of urban sustainability through its adapted strategic planning approach.

    Full Text Available China is one of the largest countries in the world with nearly 20% of the world’s population. There have been significant improvements in economy, education and technology over the last three decades. Due to substantial investments from all levels of government, the public health system in China has been improved since the 2003 severe acute respiratory syndrome (SARS outbreak. However, infectious diseases still remain a major population health issue and this may be exacerbated by rapid urbanization and unprecedented impacts of climate change. This commentary aims to explore China’s current capacity to manage infectious diseases which impair population health. It discusses the existing disease surveillance system and underscores the critical importance of strengthening the system. It also explores how the growing migrant population, dramatic changes in the natural landscape following rapid urbanization, and changing climatic conditions can contribute to the emergence and re-emergence of infectious disease. Continuing research on infectious diseases, urbanization and climate change may inform the country’s capacity to deal with emerging and re-emerging infectious diseases in the future.

    Edwards, P.P.; Kuznetsov, V.L.; David, W.I.F.; Brandon, N.P.

    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.

  7. Powering the future: Blueprint for a sustainable electricity industry

    International Nuclear Information System (INIS)

    Flavin, C.; Lenssen, N.

    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

  8. Future Transportation with Smart Grids and Sustainable Energy

    Directory of Open Access Journals (Sweden)

    Gustav R. Grob

    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.

    Urban metabolism components define the energy and material exchanges within a city and, therefore, can provide valuable information on the environmental quality of urban areas. Assessing the potential impact of urban planning alternatives on urban metabolism components (such as energy, water, carbon and pollutants fluxes) can provide a quantitative estimation of their sustainability performance. Urban metabolism impact assessment can, therefore, contribute to the identification of sustainable urban structures with regards, for example, to building types, materials and layout, as well as to location and capacity of transportation and infrastructural developments. In this way, it enables the formulation of planning and policy recommendations to promote efficient use of resources and enhance environmental quality in urban areas. The European FP7 project BRIDGE (sustainaBle uRban plannIng Decision support accountinG for urban mEtabolism) has developed a decision-support system (DSS) that systematically integrates urban metabolism components into impact assessment processes with the aim of accurately quantifying the potential effects of proposed planning interventions. The DSS enables integration of multiple spatial and non-spatial datasets (e.g. physical flows of energy and material with variables of social and economic change) in a systematic manner to obtain spatially defined assessment results and to thus inform planners and decision-makers. This multi-criteria approach also enables incorporation of stakeholders' perceptions in order to prioritise decisive assessment criteria. This paper describes the methodological framework used to develop the DSS and critically examines the results of its practical application in five European cities. - Highlights: Black-Right-Pointing-Pointer Urban metabolism in sustainability assessment of planning alternatives.

    Urban metabolism refers to the assessment of the amount of resources produced and consumed by urban ecosystems. It has become an important tool to understand how the development of one city causes impacts to the local and regional environment and to support a more sustainable urban design and planning. Therefore, the purpose of this paper was to measure the changes in material and energy use occurred in the city of Curitiba (Brazil) between the years of 2000 and 2010. Results reveal better living conditions and socioeconomic improvements derived from higher resource throughput but without complete disregard to environmental issues. Food intake, water consumption and air emissions remained at similar levels; energy use, construction materials and recycled waste were increased. The paper helps illustrate why it seems more adequate to assess the contribution a city makes to sustainable development than to evaluate if one single city is sustainable or not. - Highlights: • We assessed the urban metabolism of Curitiba (Brazil) in 2000 and 2010. • Living conditions improved due to higher material and energy use. • Socioeconomic expansion demands special attention to environmental changes. • One city cannot be sustainable by itself, as it depends on external resources. • Urban metabolism helps measuring a city's contribution to sustainable development. - The urban metabolism of Curitiba (Brazil) reveals improvement in living conditions due to increased material and energy use, but without disregard to the environment

    There are more than 1.2 billion people around the world that do not have access to drinking water. While there are plans under the United Nations Millennium Development Goals to halve this number by 2015, there are a number of regions that will be exposed to water scarcity in the coming future. Providing sufficient water for future development is a great challenge for planners and designers of water supply systems. In order to design sustainable water supplies for the future, it is important to learn how people consume water and how water consumption can be reduced. The education of future civil engineers should take into account not only technical aspects of the water supply but also the accompanying social and economical issues, and appreciated the strengths and weaknesses of traditional solutions. The Faculty of Civil Engineering, at the University of Rijeka, has begun incorporating a series of activities that engage undergraduate students and the local community to develop a mutual understanding of the future needs for sustainable management. We present one of the activities, collaboration with the Lancaster Environment Centre at Lancaster University in the UK through the field course Water and environmental management in Mediterranean context. The course, which is designed for the Lancaster University geography students, features a combination of field trips and visits to provide an understanding of the socio-economic and environmental context of water management in two counties (Istra and Primorsko-Goranska). Students from Lancaster visit the Croatian water authority and a regional water company, where they learn about current management practices and problems in managing water supplies and demand through the year. They make their own observations of current management practices in the field and learn about water consumption from the end users. One day field visit to a village in the area that is still not connected to the main water supply system is

  16. Futures Analysis of Urban Land Use and Wetland Change in Saskatoon, Canada: An Application in Strategic Environmental Assessment

    Full Text Available This paper presents a scenario-based approach to strategic environmental assessment (SEA for wetland trend analysis and land use and land cover (LUC modeling in an urban environment. The application is focused on the Saskatoon urban environment, a rapidly growing urban municipality in Canada’s prairie pothole region. Alternative future LUC was simulated using remote sensing data and city spatial planning documentation using a Markov Chain technique. Two alternatives were developed and compared for LUC change and threats to urban wetland sustainability: a zero alternative that simulated trends in urban development and wetland conservation under a business as usual scenario, in the absence of prescribed planning and zoning actions; and an alternative focused on implementation of current urban development plans, which simulated future LUC to account for prescribed wetland conservation strategies. Results show no improvement in future wetland conditions under the city’s planned growth and wetland conservation scenario versus the business as usual scenario. Results also indicate that a blanket wetland conservation strategy for the city may not be sufficient to overcome the historic trend of urban wetland loss; and that spatially distributed conservation rates, based on individual wetland water catchment LUC peculiarities, may be more effective in terms of wetland conservation. The paper also demonstrates the challenges to applied SEA in a rapidly changing urban planning context, where data are often sparse and inconsistent across the urban region, and provides potential solutions through LUC classification and prediction tools to help overcome data limitations to support land use planning decisions for wetland conservation.

    2014-05-01

    Full Text Available Planning and implementation of sustainable urban neighborhoods has led in Europe and in other countries to the development of some recognized best practices. Each of these cases has followed specific aims and methodologies but it is still far the systematization of the results and the translation of the good practices into action lines.  The paper involves the necessity of new tools for local planning directed to the overall sustainability of the city. Sustainable energy, reduction of the climate-change causes, waste reduction, attention to water resources and to the natural ones are specific operational elements. A possible way to face this challenge is to consider the potentialities of executive plans addressed to increase the sustainability of urban areas starting from limited portions of they. These plans should foresee the minimum impact of volumes and functions to be set up, will provide for the realization of public spaces with zero or almost zero impact, will promote the integration of all the technologies to reduce consumption and encourage energy generation, in order to increase the resilience of the city reducing its vulnerability.  On this basis, aim of the paper is to deepen the issue of the measure of the expected results. To this purpose it is necessary to structure a new certification system (Urban Labelling that can be able to assign a specific sustainability level to a plan using both traditional and new indexes. The same system can also be applied to existing urban areas and as a basis for evaluating reward operations. The impact of the new tool will be cultural (to switch by a description to the facts in relation to urban sustainability, economic (to involve the supply chain from design, implementation, and urban transformation and technological (the sustainability of urban areas requires the use of advanced technologies not only for the buildings but also in the control of green areas, public spaces and mobility.

    In this paper the notion of urban infrastructure resilience is formulated being expressed verbally and strictly in conditional probability terms. It is further used to formulate several most important features of a smart city. This multidisciplinary and multifaceted approach is used to explain the concept of quantitative resilience in urban design, operation, managing urban risk and mitigating of the consequences of a natural or industrial disaster. The extremely urgent problem is formulated on how to connect the physical and spatial (core) resiliencies with the functional, organizational, economic and social resiliencies.

    The changes happen quickly in today's world, simultaneously interacting with technological advances in the sciences and new paradigms socio-political and economic, in search of a sustainable future and a present with emergency strategies for the preservation of humanity and the planet "Earth ". Currently, the mobility of people in the intra-urban space is being threatened by congestion, pollution resulting from the appreciation of the culture of personal transport and the precariousness of public transportation. In the city of João Pessoa (PB), the subject of this finding for these disorders. Workers suffer the consequences of daily stress takes to access home-work, difficulty in arriving at the right time to the workplace and adverse reactions caused by pollution. The VLT (Light Rail Vehicle) has been presented as a viable solution to the problems of public transport, with several experiments that can be seen as positive in the world. This work involves the implementation of a public transport system based on VLT Corridor along the Avenue Dom Pedro II, in João Pessoa (PB), aiming to acquire a good transport network for use of the population, reduce the number of vehicles on process, minimize pollution and optimize urban mobility.

    Full Text Available Green spaces within residential areas provide important contributions to the sustainability of urban systems. Therefore, studying the characteristics of these areas has become a research priority in cities worldwide. This project evaluated various aspects of the plant biodiversity of residential yards (i.e., front yards and back yards within the Río Piedras watershed in the San Juan metropolitan area of Puerto Rico. Our work included gathering information on vegetation composition and abundance of woody species (i.e., trees, shrubs, palms, ferns and large herbs (>2 m height, species origin (native vs. introduced, and species uses (ornamental, food, and medicinal plants. A total of 424 yards were surveyed within an area of 187,191 m². We found 383 woody species, with shrubs being the most abundant plant habitat. As expected, residential yards hosted a disproportionate amount of introduced species (69.5%. The most common shrub species were all non-native ornamentals, whereas the most common tree species included food trees as well as ornamental plants and two native species. Front yards hosted more ornamental species per unit area than backyards, while the latter had more food plants. The high amount of introduced species may present a challenge in terms of implementation of plant conservation initiatives if there is no clear definition of urban conservation goals. On the other hand, the high frequency of yards containing food plants may facilitate the development of residential initiatives that could provide future adaptive capacity to food shortages.

Di banyak kota di belahan bumi bagian selatan, investasi pada Bus Rapid Transit (BRT memberikan kesempatan untuk peningkatan tersebut. Akan tetapi, sampai saat ini, sistem BRT telah gagal dalam menciptakan pembangunan yang kompak dan multi-guna bukan saja karena kurangnya perencanaan strategis kawasan stasiun tetapi juga dampak dari penempatan jalur-jalur dan stasiun pada wilayah perkotaan yang stagnan dan pada median jalan yang sibuk. Sistem BRT selama ini dipertimbangkan dan dirancang sebagai suatu investasi pergerakan dan bukan pembentuk kota. Disebabkan mayoritas pertumbuhan kota di masa depan di seluruh dunia akan berada pada kota-kota menengah yang cocok untuk investasi BRT, kesempatan untuk membuat sistem BRT sebagai investasi pembentuk kota tidak boleh disia-siakan.

The integration of transport infrastructure and urban development must be elevated in importance. In many cities of the Global South, recent Bus Rapid Transit (BRT investments provide an unprecedented opportunity to do just that. To date, however, BRT systems have failed to leverage compact, mixed-use development due not only to little strategic station-area planning but also factors like siting lines and stations in stagnant urban districts and busy roadway medians. BRT systems are being conceived and designed as mobility investments rather than city-shaping ones. Given that the majority of future urban growth worldwide will be in intermediate-size cities well-suited for BRT investments, the opportunities for making these not only mobility

  10. Conflicting strategies towards sustainable heating at an urban junction of heat infrastructure and building standards

    2015-01-01

    Approaches to ‘sustainability transitions’ stress the possibility of aligning actors around a shared vision of the future, e.g. at the scale of a city. Empirical accounts reveal how difficult such coordination often is due to contradictory views involved. How can we better understand related processes of searching and negotiation? What does this mean for the organization of decision making processes regarding long-term infrastructural change? We analyze a conflict which erupted in Freiburg, Germany when two strategies of reducing environmental impacts of space heating were to be applied in the Vauban ‘model district’: A) Efficient co-generation of heat and power (CHP) combined with district heating systems (DHS), and B) Reducing heat demand by low-energy designs and ambitious energy standards (‘passive house standard’). In order to understand the politics of infrastructure development, we unravel 1) enabling factors and driving forces of the conflict, 2) normative content of opposing viewpoints, 3) resources tapped into for settling the disagreement, and 4) the institutional setup of such decision making about energy policy priorities in the municipality. We reflect on implications of such a perspective on how policies and how governance arrangements should ideally be shaped and take a brief outlook on further research needed. - Highlights: • Foregrounds likeliness of conflicts over strategies within sustainability transitions. • District heating systems can be incommensurate with low energy building standards. • Studies one such conflict in an urban context (Freiburg, Germany) in depth. • Processes of urban planning can reveal frictions within and between infrastructures. • Can such junctions as opportunities for re-negotiation of strategies be anticipated?

    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.

    Full Text Available Sustainable spatial development is a generally accepted objective and principle in spatial planning. It is implemented mainly by regulations in the sectors for management of natural resources, but not comprehensively in implementing regulations for urban space management. One of the most important instruments of spatial planning at local level is land use, for which there is no comprehensive framework of implementing measures for achieving sustainable spatial objectives in urban areas. In accordance with the review and critical analysis of literature, there are four measures presented in the paper: protection of natural resources and reduction of environmental-climate risks, compact urban structure, mixed-use and accessibility of urban functions. The review and analysis have shown that the listed measures enable sustainable development of urban areas, but only if they are planned and implemented in accordance with supporting physical, social and economic elements of urban space. In the conclusion, indicators which can assess the level of sustainability in land use design are presented and guidelines for restructuring land use in existing settlement areas are described.

  15. Creative ideation and adaptive reuse: a solution to sustainable urban heritage conservation

    Science.gov (United States)

    Hasnain, H.; Mohseni, F.

    2018-03-01

    The rapid phenomenon of urbanization in the last century has resulted in abandonment of historic urban centers and still today attracting people to suburbs and newly developed districts. This urban expansion poses a serious threat to historic properties when people opt to move away leaving behind their heritage. The adaptive reuse of heritage is considered to be a dominant strategy for handling this issue bypassing demolition of heritage properties. However, the adaptive reuse cannot only consider the preservation of the heritage as the structural retrofit or functional revitalization but rather it needs to enunciate the image and the creative ideation that reflect upon the future of heritage. Consequently, this paper aims to examine the role of branding as an innovative source of ideation in the implication of adaptive reuse on heritage. In this regards, the case study of Zalando outlet store in Berlin is selected, which is an old building situated in the commercial district of the city in a wide range of styles and heritage buildings from the middle ages. This research uses semi-structured interviews to examine the significance of Brand making in a successful adaptive reuse process. The findings indicate that the importance of the outlet building lies not only in its physical fabric or commercial aspects, but the spirit of the place that lies in the magical essence of big labels as emblems. This underlying essence of place stimulated the adaptation of building in a way that it surpasses the physical and functional aspect of a building and makes it merge in new times and new sustainable development.

    The sustainability agenda has maintained its importance since the days, when the production system took its capitalist form, as well as the population in the urban areas started to rise. Increasing number of both goods and the people have caused the degradation of the certain systems, which generate the urban areas. These systems could mainly be classified as social, environmental, physical and economical systems. Today, urban areas still have difficulty to protect those systems, due to the significant demand of the population. Therefore, studies related with the sustainable issues are significant in the sense of continuity of the urban systems. Therefore, in this paper, those studies in the context of the effects of physical decisions taken in the spatial planning process on urban sustainability, will be examined. The components of the physical decisions are limited to land use, density and design. Land use decisions will be examined in the context of mixed land use. On the other hand, decisions related with density will be analyzed in the sense of population density and floor area ratio (FAR). Besides, design decisions will be examined, by linking them with neighborhood design criteria. Additionally, the term of urban sustainability will only be limited to its social and environmental contexts in this study. Briefly stated, studies in the sustainable literature concerned with the effects of land use, density and design decisions taken in the spatial planning process on the social and environmental sustainability will be examined in this paper. After the compilation and the analyze of those studies, a theoretical approach will be proposed to determine social and environmental sustainability in the context of land use, density and design decisions, taken in the spatial planning process.

In this respect, the authors examined the effect of urban characteristics of unplanned settlements on SD in the Egyptian context, focusing on the type of unplanned growth on agricultural land. The output of the analysis were fourfold. First of all, we provide a brief overview of previous research on the main types of unplanned settlements in GCMR and the sustainability definition according to the Egyptian context. Secondly, we had a discussion with the local government during our field survey in GCMR to determine the study samples, the main urban characteristics, and the sustainability evaluation criteria in the Egyptian context. Thirdly, through the comparative analysis and geographic information system (GIS, we examined how the character of urban development affected per capita four urban measures in a cross-section of two settlements, one represented the unplanned settlements and other as a comparative planned sample to determine the real gap. Finally, by using the evaluation matrix, the help and block items are estimated for each measure of urban characteristics, providing substantive evidence on how the four measures of urban characteristics have been affected by the urban sprawl.

    2012-01-01

    Design of a sustainable city has changed the traditional centralized urban wastewater system towards a decentralized or clustering one. Note that there is considerable spatial variability of the factors that affect urban drainage performance including urban catchment characteristics. The potential options are numerous for planning the layout of an urban wastewater system, which are associated with different costs and local environmental impacts. There is thus a need to develop an approach to find the optimal spatial layout for collecting, treating, reusing and discharging the municipal wastewater of a city. In this study, a spatial multi-objective optimization model, called Urban wastewateR system Layout model (URL), was developed. It is solved by a genetic algorithm embedding Monte Carlo sampling and a series of graph algorithms. This model was illustrated by a case study in a newly developing urban area in Beijing, China. Five optimized system layouts were recommended to the local municipality for further detailed design.

    Directory of Open Access Journals (Sweden)

    Chris De Gruyter

    2016-12-01

    Full Text Available Previous studies of public transport sustainability in cities have been very limited to date, particularly in more developing countries located throughout Asia and the Middle East. This paper assesses the sustainability of urban public transport systems in cities by adopting a quantitative measurement framework containing 15 public transport sustainability indicators. It compares aggregate sustainability performance of urban public transport in international regions of cities, and then examines the relative sustainability of selected cities in the Asia and Middle East region. The world region analysis shows that Eastern Europe, Asia, and Latin America achieve the highest aggregate normalised scores for sustainable public transport, in that order. In general, the results suggest that western developed countries (Western Europe, North America, and Oceania have better performance on environmental and social indicators but poorer performance on system effectiveness and economic indicators. Asia and Latin America perform the other way round; better on economic and system effectiveness and worse on social and environmental indicators. Eastern Europe is one of the few regions with higher level performance all round. The city-based analysis of Asia/Middle East suggested that out of the 26 cities studied, the top 3 cities in terms of sustainable public transport in the Asia and Middle East Region are: 1st, Manila (Philippines; 2nd, Tokyo (Japan; and 3rd, Chennai (India. Dubai (United Arab Emirates (UAE, rated 26th, Shizuoka (Japan, rated 25th and Kuala Lumpur (Malaysia, rated 24th were the lowest rated cities. The paper explores the implications of the findings and makes suggestions for future research.

  20. The role of underground construction for the mobility, quality of life and economic and social sustainability of urban regions

    Directory of Open Access Journals (Sweden)

    Manuel Luís Tender

    Full Text Available Abstract Tunnelling has been used for several purposes for thousands of years. In the coming years the world's population will increase in the urban areas. So, the urban centres will have to adapt, in order to guarantee that their future population will have the necessary and sustainable growth. Due to the constraints for surface construction, also connected to environmental issues, this population growth will imply a greater use of the underground. With this optimal growth, the population of the cities will have better mobility, quality of life, and economic and social sustainability. In a first phase, this report will present a historic approach to tunnelling and its foreseeable future. Afterwards, we will present some considerations on the three factors which tunnelling impacts: mobility, quality of life and social sustainability. As a case study, we will analyse the 2nd phase of the construction of the Marão Tunnel (TDM - the longest ever built in the Iberian Peninsula- and describe the options made regarding each of those factors. In this case study, the options implemented made it possible to successfully execute the works. For the industry, this work is important because it describes a successful management of the aspects under analysis.

    This paper aims to investigate the links between materiality and society at a conceptual level, using examples from the author's decade of research in several fields relevant to the issue. With current talk of the need for `sustainability' and `resilience' reaching fever pitch in industry, politics and other arenas, there is a regrettable tendency to muddle the meaning of these words. Drawing on original research carried out in the UK, China, Germany, and Australia, and using the conceptual approaches of actor-network theory (ANT) and urban political ecology (UPE), the author invites us to re-engage with the materiality of society and how we, as businesses, consumers and thinkers, can advance sustainability and resilience through this re-engagement. We will ask what sustainability and resilience mean, for whom and in what context. We will also look at how we can shift thinking and reinvigorate these words, by contributing to the dialogue between the social sciences and business and industry. Specific examples will be taken from the UK and Chinese steel industries; climate-sensitive urban design in Manchester and Stuttgart; and housing construction and affordability in Scotland and Australia, thus covering a wide range of issues related to urban sustainability and resilience in relation to materiality.

    Full Text Available Development in space reflects the consequences of development decisions in all areas of life and work. For this purpose all questions with regard to spatial planning should be solved comprehensively, in connection with economic and social development, while taking into consideration natural potentials and limitations and observing the principles for sustainable balanced development. To measure the sustainability of a place a series of indicators have to be devised. An example of the use of these indicators is presented.

    2005-01-01

    Can Germany give up gasoline and power from coal or nuclear energy and how much does it cost? The book does away with all common misunderstandings due to renewable energy sources and describes a compatible model for a sustainable energy mixing in future. Nevertheless fossil fuels are not denounced but seen as a platform for the advanced system. The author explains first why objections to renewable energy sources base on bad information, and pursues quite an other argumentation as such authors emphasizing the potential of these energy sources. Than he shows in detail the possibility of the optimal energy mixing for biomass, solar power, wind power, geothermal energy, hydropower and energy efficiency. The environment will reward us for this and instead buying expensive resources from foreign countries we will create work places at home. The number of big power plants - taking into account safety risks - will decrease and small units of on-site power generation feeded with this renewable sources will play more and more an important role.

    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.

  8. Future Forests. Sustainable Strategies under Uncertainty and Risk

    Energy Technology Data Exchange (ETDEWEB)

    2009-07-01

    Climate change, globalization, and increased consumption of materials and energy leads to higher pressure on forest resources. The task of intensifying forestry to produce more timber, paper, and energy, while at the same time ensuring ecosystem services, such as biodiversity and recreation, is a complex one. Difficult decisions have to be made if we are to strike a balance between these demands. These decisions have to be supported by scientifically-based land-use strategies to deal with tradeoffs on different scales. The vision of Future Forests is to take a significant step forward in this complicated task. The Program has a long-term perspective (50-100 years) and will consider changes in climate, as well as global and market development as major factors likely to have a strong influence on forest management and forest landscapes in the future. In this context, uncertainties, vulnerability, and the adaptive capacity of social-ecological systems must also be considered. The Program's promise to society is: Future Forests will create knowledge and tools to enable sustainable decisions for the future of one of our most important resources - our forests. To fulfill this promise, the Program has the ambition to constitute a platform where researchers from different disciplines, and practitioners from several sectors, can interact. The program will combine empirical research with modeling, scenario analysis, and synthesis work in order to produce excellent science and applications. Much of the multidisciplinary research performed in the Program will be done in the Component Projects. These research groups will be responsible for producing detailed, high quality scientific results that can both be incorporated into the scenarios and be directly relevant for our stakeholders. The Center for Forest System Analyses and Synthesis (ForSA) will form a unifying force in Future Forests. The main goal for this center is to develop skills in scenario analyses and to

    Full Text Available The increasing level of antropopression has a negative impact on environmental resources and has reached the level of our planetary boundaries. One limitation is land use change caused by urbanization. Global policies prove the need to undertake action in order to develop more sustainable human settlements, which would be adapted better to potential future climate change effects. Among such changes are the increase of average temperatures and extreme events like heat waves. Those changes are more severe in urban areas due to land use development, and result in the urban heat island effect (UHI, which has a negative impact on the thermal comfort of citizens. The paper presents a decision support system that can be used for the assessment of areas to the potential exposure to the UHI effect. The system integrates scenario analysis, land use modelling in cellular automata (Metronamica, and an indicator-based assessment in a geographic information system (ArcGIS. The applicability of the model is illustrated through developing scenarios for the future land use allocation of the Wrocław Larger Urban Zone (Poland. The results of the calculations show which scenario is the least vulnerable to UHI effects. Moreover, for each scenario, cores of urban areas were identified, in which certain urban design patterns accounting for adaptation to climate change could be implemented. The study provides a guideline for local authorities on where to focus actions in order to create more sustainable urban structures and to better adapt to climate change and environmental extremes.

  10. Advantages of integrated and sustainability based assessment for metabolism based strategic planning of urban water systems.

    Despite providing water-related services as the primary purpose of urban water system (UWS), all relevant activities require capital investments and operational expenditures, consume resources (e.g. materials and chemicals), and may increase negative environmental impacts (e.g. contaminant discharge, emissions to water and air). Performance assessment of such a metabolic system may require developing a holistic approach which encompasses various system elements and criteria. This paper analyses the impact of integration of UWS components on the metabolism based performance assessment for future planning using a number of intervention strategies. It also explores the importance of sustainability based criteria in the assessment of long-term planning. Two assessment approaches analysed here are: (1) planning for only water supply system (WSS) as a part of the UWS and (2) planning for an integrated UWS including potable water, stormwater, wastewater and water recycling. WaterMet(2) model is used to simulate metabolic type processes in the UWS and calculate quantitative performance indicators. The analysis is demonstrated on the problem of strategic level planning of a real-world UWS to where optional intervention strategies are applied. The resulting performance is assessed using the multiple criteria of both conventional and sustainability type; and optional intervention strategies are then ranked using the Compromise Programming method. The results obtained show that the high ranked intervention strategies in the integrated UWS are those supporting both water supply and stormwater/wastewater subsystems (e.g. rainwater harvesting and greywater recycling schemes) whilst these strategies are ranked low in the WSS and those targeting improvement of water supply components only (e.g. rehabilitation of clean water pipes and addition of new water resources) are preferred instead. Results also demonstrate that both conventional and sustainability type performance indicators

    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

    Aiming at efficient and mindful use of natural resources while enabling social cohesion and economic development; sustainable development is one of the most emerging phenomenon in last decade. In this regard, role of urban development is critical by means of achieving sustainability since more than half of the world's population lives in cities. However, there is no solid and widely accepted approach for sustainability assessment in land use planning because there is not enough evidence on the relation between land use plans and environmental sustainability. With the basic aim of setting up relation between environmental sustainability and urban plans, this study utilizes ecosystem services phenomenon to define sustainability performance of a land use plan. Since ecosystem services can easily be related with land cover and land use they can be used as an efficient tool to act as indicators of sustainability. Meanwhile, while urban plans can provide ecosystem services and their level of service provision can be quantified, this is not solely enough for understanding its sustainability. Because it is also known that a land use plan mostly has negative impact on sustainability. Hence, this study embraces land use plans as a source of ecosystem services and environmental impacts. The difference between these entities are assumed to be the sustainability performance of a plan. The analysis relies on four parameters: ecosystem service capacity (environmental impact capacity), areal quantity of a land cover / use function, fragmantation level of the land use / cover and weight of ecosystem services / environmental impacts. Lastly, this approach is adopted for Istanbul's environmental master plan of 2009 and actual land cover of the same period. By calculating both data's environmental performance, the change of sustainability level sourced from environmental plan is analyzed.

    2018-03-01

    Not only is Jakarta the largest metropolitan area in Southeast Asia, it is the also one of the most dynamic, though beset with most of the urban problems experienced in twenty-first century Southeast Asia. Batavia, colonial capital of the Netherland Indies in the first half of the 20th century was a small urban area of approximately 150,000 residents. In the second half, Batavia became Jakarta, the 28 million megacity capital of independent Indonesia. Among many urban problems, one major problem plagued Jakarta in the last two decades is traffic congestions. This paper discusses the extent to which rapid urbanization in Jakarta has contributed to the need for sustainable transportation policies in Jakarta. The development of MRT could be viable solutions to alleviate the acute traffic jams in Jakarta. Jakarta will need to implement other innovative sustainable transportation policies including promoting active live through more walking and bicycling, carpool matching services, shuttle services, telecommuting and downzoning in downtown areas.

    2015-01-01

    Los Alamos National Laboratory's IAEA Neutron Coincidence Counting (INCC) code is the standard tool for neutron coincidence counting measurements. INCC software and its' predecessors were originally implemented in the 1970s. The measurement and analysis techniques perfected in the code arise from many years of laboratory and field experience by nuclear engineers and physicists. Covering the full arc of INCC's lifecycle, we discuss the engineering approaches used for conception, original development, worldwide deployment of the stand-alone Windows application, more than a decade of sustained maintenance support, and our recent work to carry INCC successfully into future applications. We delve into the recent re-architecture of the INCC code base, an effort to create a maintainable and extensible architecture designed to preserve the existing INCC code base while adding support for new analyzes and instruments (e.g., List Mode PTR-32 and the List Mode Multiplicity Module). INCC now consists of separate modules implementing attended instrumentation control, data file processing, statistical and Pu mass calculation and analyzes, list mode counting and analyzes, reporting functions, and a database support library. Separating functional capabilities in this architecture enables better testing, isolates development risk and enables the use of INCC features in other software systems. We discuss our approach to handling divergent data and protocol support as a result of this re-architecture. INCC has complex testing requirements; we show how the testing effort was reduced by breaking the software into separate modules. This new architecture enables integration of INCC analysis into the IAEA's new Integrated Review and Analysis Programme (iRAP) data review system. iRAP is based on the respected Euratom Comprehensive Review Inspector Software Package (CRISP) software framework, and is expected to be the future data review system for IAEA and Euratom

    Bergesen, Joseph D.; Suh, Sangwon; Baynes, Timothy M.; Kaviti Musango, Josephine

    2017-12-01

    As cities grow, their environmental and natural resource footprints also tend to grow to keep up with the increasing demand on essential urban services such as passenger transportation, commercial space, and thermal comfort. The urban infrastructure systems, or socio-technical systems providing these services are the major conduits through which natural resources are consumed and environmental impacts are generated. This paper aims to gauge the potential reductions in environmental and resources footprints through urban transformation, including the deployment of resource-efficient socio-technical systems and strategic densification. Using hybrid life cycle assessment approach combined with scenarios, we analyzed the greenhouse gas (GHG) emissions, water use, metal consumption and land use of selected socio-technical systems in 84 cities from the present to 2050. The socio-technical systems analyzed are: (1) bus rapid transit with electric buses, (2) green commercial buildings, and (3) district energy. We developed a baseline model for each city considering gross domestic product, population density, and climate conditions. Then, we overlaid three scenarios on top of the baseline model: (1) decarbonization of electricity, (2) aggressive deployment of resource-efficient socio-technical systems, and (3) strategic urban densification scenarios to each city and quantified their potentials in reducing the environmental and resource impacts of cities by 2050. The results show that, under the baseline scenario, the environmental and natural resource footprints of all 84 cities combined would increase 58%-116% by 2050. The resource-efficient scenario along with strategic densification, however, has the potential to curve down GHG emissions to 17% below the 2010 level in 2050. Such transformation can also limit the increase in all resource footprints to less than 23% relative to 2010. This analysis suggests that resource-efficient urban infrastructure and decarbonization of

    2008-01-01

    Full Text Available Over the last two decades, there has been an intensive discourse and research about measuring sustainable urban development. Many cities, regions and countries have decided to introduce indicators for monitoring and measuring the progress towards sustainability. Today there is a wide spread perception that information on the environment in general, and urban environment in particular, is the determinant of effective rational decisions and allocation of resources. Such information would enable planners and decision makers to formulate redistributive policies and programmes to address some of the disparities that exist in a post-socialist city. Cities of the post-socialist world characterized by sharp disparities, socio-economic contrasts and environmental degradation provide an excellent laboratory for tracing information on the quality of urban life. The current situation in the emerging Croatian coastal city of Zadar reflects the diversity of the post-socialist urban change in a very fragile Mediterranean landscape. This paper takes a critical look at sustainable development and its measurements. It describes the participatory approach through which different local communities in Zadar were evaluating quality of life based on basic pillars of sustainable development. The identification and collection of their opinions provide valuable data base and community input into urban governance and development planning decision making.

    Meeting our 21st century challenges will require sustainable energy planning by our cities, where over half of the population resides. This already has become evident in the State of California, which has set rigorous greenhouse gas emission reduction targets and timeframes. To attain these targets will necessitate technically-integrated and cost-optimum solutions for innovative asset development and management within urban communities. Using California as a case study, this paper focuses on the crucial role for sustainable energy planning in creating the context and conditions for integrating and optimizing clean and efficient energy use with the urban built environment and infrastructure.

    2016-05-01

    Full Text Available Anthropogenic activity interacts with urban form and inner metabolic processes, ultimately impacting urban sustainability. China’s cities have experienced many environmental issues and metabolic disturbances since the nation-wide market-oriented “reform and opening-up” policy was adopted in the 1980s. To analyze urban reform policy impacts and metabolism sustainability at a settlement scale, this study provides an integrated analysis to evaluate settlement metabolism and sustainability using a combination of emergy analysis and sustainability indicators based on scrutiny of two typical settlements (one pre- and one post-reform. The results reveal that housing reform policy stimulated better planning and construction, thereby improving built environmental quality, mixed functional land use, and residential livability. The pre-reform work-unit settlements are comparatively denser in per capita area but have less mixed land use. Housing reform has spatially changed the work–housing balance and increased commuting travel demand. However, short commuting distances in pre-reform settlements will not always decrease overall motor vehicle usage. Integrating non-commuting transport with local mixed land-use functional planning is a necessary foundation for sustainable urban design. Functional planning should provide convenient facilities and infrastructure, green space, and a suitable household density, and allow for short travel distances; these characteristics are all present in the post-reform settlement.

We conclude with two main points, first, that the theoretical and pragmatic aspects of urban sustainability in Montreal have been treated in an organic, complex, dynamic and flexible way, allowing social participation and the inclusion of the values of all stakeholders, which are both key elements to follow the path towards sustainability; and secondly, that the approach to an object with such features requires the construction of complex, organic and methodological processes.

  8. Geochemical legacies and the future health of cities: A tale of two neurotoxins in urban soils

    Directory of Open Access Journals (Sweden)

    Gabriel M. Filippelli

    2015-07-01

    Full Text Available Abstract The past and future of cities are inextricably linked, a linkage that can be seen clearly in the long-term impacts of urban geochemical legacies. As loci of population as well as the means of employment and industry to support these populations, cities have a long history of co-locating contaminating practices and people, sometimes with negative implications for human health. Working at the intersection between environmental processes, communities, and human health is critical to grapple with environmental legacies and to support healthy, sustainable, and growing urban populations. An emerging area of environmental health research is to understand the impacts of chronic exposures and exposure mixtures—these impacts are poorly studied, yet may pose a significant threat to population health. Acute exposure to lead (Pb, a powerful neurotoxin to which children are particularly susceptible, has largely been eliminated in the U.S. and other countries through policy-based restrictions on leaded gasoline and lead-based paints. But the legacy of these sources remains in the form of surface soil Pb contamination, a common problem in cities and one that has only recently emerged as a widespread chronic exposure mechanism in cities. Some urban soils are also contaminated with another neurotoxin, mercury (Hg. The greatest human exposure to Hg is through fish consumption, so eating fish caught in urban areas presents risks for toxic Hg exposure. The potential double impact of chronic exposure to these two neurotoxins is pronounced in cities. Overall, there is a paradigmatic shift from reaction to and remediation of acute exposures towards a more nuanced understanding of the dynamic cycling of persistent environmental contaminants with resultant widespread and chronic exposure of inner-city dwellers, leading to chronic toxic illness and disability at substantial human and social cost.

    Full Text Available Understanding the dynamics of urban ecosystem services is a necessary requirement for adequate planning, management, and governance of urban green infrastructure. Through the three-year Urban Biodiversity and Ecosystem Services (URBES research project, we conducted case study and comparative research on urban biodiversity and ecosystem services across seven cities in Europe and the United States. Reviewing > 50 peer-reviewed publications from the project, we present and discuss seven key insights that reflect cumulative findings from the project as well as the state-of-the-art knowledge in urban ecosystem services research. The insights from our review indicate that cross-sectoral, multiscale, interdisciplinary research is beginning to provide a solid scientific foundation for applying the ecosystem services framework in urban areas and land management. Our review offers a foundation for seeking novel, nature-based solutions to emerging urban challenges such as wicked environmental change issues.

    Increasing population and industrialization are continuously oppressing the existing energy resources and depleting the global fuel reservoirs. The elevated pollutions from the continuous consumption of non-renewable fossil fuels also seriously contaminating the surrounding environment. The use of alternate energy sources can be an environment-friendly solution to cope these challenges. Among the renewable energy sources biofuels (biomass-derived fuels) can serve as a better alternative to reduce the reliance on non-renewable fossil fuels. Bioethanol is one of the most widely consumed biofuels of today's world. The main objective of this review is to highlight the significance of lignocellulosic biomass as a potential source for the production of biofuels like bioethanol, biodiesel or biogas. We discuss the application of various methods for the bioconversion of lignocellulosic biomass to end products i.e. biofuels. The lignocellulosic biomass must be pretreated to disintegrate lignocellulosic complexes and to expose its chemical components for downstream processes. After pretreatment, the lignocellulosic biomass is then subjected to saccharification either via acidic or enzymatic hydrolysis. Thereafter, the monomeric sugars resulted from hydrolysis step are further processed into biofuel i.e. bioethanol, biodiesel or butanol etc. through the fermentation process. The fermented impure product is then purified through the distillation process to obtain pure biofuel. Renewable energy sources represent the potential fuel alternatives to overcome the global energy crises in a sustainable and eco-friendly manner. In future, biofuels may replenish the conventional non-renewable energy resources due to their renewability and several other advantages. Lignocellulosic biomass offers the most economical biomass to generate biofuels. However, extensive research is required for the commercial production of an efficient integrated biotransformation process for the production of

    2014-10-01

    Full Text Available This research is motivated by the increasing threat of urban heat waves that are likely worsened by pervasive global warming and urbanization. Different regions of the city including urban, borderland and rural area will experience different levels of heat health risk. In this paper, we propose an improved approach to quantitatively assess Beijing’s heat health risk based on three factors from hazard, vulnerability and especially environment which is considered as an independent factor because different land use/cover types have different influence on ambient air temperatures under the Urban Heat Island effect. The results show that the heat health risk of Beijing demonstrates a spatial-temporal pattern with higher risk in the urban area, lower risk in the borderland between urban and rural area, and lowest risk in the rural area, and the total risk fluctuated dramatically during 2008–2011. To be more specific, the heat health risk was clearly higher in 2009 and 2010 than in 2008 and 2011. Further analysis with the urban area at sub-district level signifies that the impervious surface (urban area such as buildings, roads, et al. ratio is of high correlation with the heat health risk. The validation results show that the proposed method improved the accuracy of heat health risk assessment. We recommend that policy makers should develop efficient urban planning to accomplish Beijing’s sustainable development.

  19. Evaluating Urban Quality: Indicators and Assessment Tools for Smart Sustainable Cities

    Full Text Available The analysis of urban sustainability is key to urban planning, and its usefulness extends to smart cities. Analyses of urban quality typically focus on applying methodologies that evaluate quality objectives at environmental, urban, and building levels. Research has shown that a system of indicators can be useful for developing qualitative and quantitative descriptors of urban environments. The first step in this study was to formulate a methodology to measure the quality of urban life based on investigative checklists and objective and subjective indicators, aggregated to develop an index to evaluate a city’s level of smart urban quality. The second step was to apply this methodology to evaluate the city of Cagliari (Italy at the neighbourhood scale, which is considered by literature the most suitable as a self-sufficient spatial unit for showing redevelopment results. In addition to sharing its research findings, this study aims to verify whether the methodology can be applied to similar urban contexts. The main outcomes of this research pertain to opportunities to numerically measure both objective and subjective aspects that affect urban quality. In this way, the most critical areas to be requalified have been highlighted in order to prepare policies congruent with the local context.

    2018-04-01

    Full Text Available This paper examines the sustainability of urban development through the livelihood conditions of slum dwellers in Bangladesh. The empirical data were collected through interview schedule and FGD from 97 respondents in two slum areas of Bangladesh. The respondents were selected purposively from the second largest city of Bangladesh namely, Chittagong. The results clearly indicate that there exist significant diversity and differences of sustainability indicators, particularly household and housing characteristics, health, drinking water, waste disposal system and security. More specifically, the finding shows that slum dwellers have been experiencing with a wide range of substandard, overcrowded and unhealthy housing conditions in one hand. On the other hand, they have scarce and insufficient health, sanitation, water and waste disposal services which are unswervingly impeding to sustainable development in urban areas. Although the majority of slum dwellers have access to electricity, they are still threatened by the insecurities of women, drug dealing, eviction and natural disaster. Therefore, the findings suggest a holistic approach to address the multi-faceted sustainability issues that affect the livelihoods of slum dwellers within the framework of context-driven development policy of the country.

    Urban housing renewal aims to get added value while maintaining the sustainability of its environmental function and quality [4]. This research discusses the urban renewal which is done by rebuilding the affected area with walk-up flats. There are four aspects to be considered in achieving sustainability, namely: environmental, social, economic, and cultural [14]. This study is focused on cultural aspect. Sustainable walk-up flats, viewed from the micro context perspective, can later be used as one of the terms of reference in assessing the success of urban renewal projects in Indonesia. Especially in coastal areas, it becomes more challenging because coastal communities have different characteristics and the existing urban renewal flats are not necessarily appropriate for the coastal community. The methods used in this study are explorative, descriptive, ex- post, cross-sectional and synchronic evaluation. This research describes the characteristics of citizens, activities at home and the environment. Thus, the conclusions which are drawn by deductive reasoning are done using frequency, mean, etc. A mixed research method is applied combining with the analysis of quantitative and qualitative data collection and interpretation, including determining quantitative indicators and space design attributes, and qualitative user needs. This research is located in Surabaya as a sample of coastal cities with urban and environmental problems. The results of this study are the findings of indicators, directions, and concepts for Sustainable Housing Development in Coastal Areas which further can be made as scientific recommendation (to support the Housing Theory and Urban Renewal) and contribute to practical guidelines for sustainable low-cost walk-up flats in coastal areas.

    2016-07-01

    Full Text Available Although China has promoted the construction of Chinese Sustainable Ground Transportation (CSGT to guide sustainable development, it may create substantial challenges, such as rapid urban growth and land limitations. This research assessed the effects of the Hangzhou Bay Bridge on impervious surface growth in Cixi County, Ningbo, Zhejiang Province, China. Changes in impervious surfaces were mapped based on Landsat images from 1995, 2002, and 2009 using a combination of multiple endmember spectral mixture analysis (MESMA and landscape metrics. The results indicated that the area and density of impervious surfaces increased significantly during construction of the Hangzhou Bay Bridge (2002–2009. Additionally, the bridge and connected road networks promoted urban development along major roads, resulting in compact growth patterns of impervious surfaces in urbanized regions. Moreover, the Hangzhou Bay Bridge promoted the expansion and densification of impervious surfaces in Hangzhou Bay District, which surrounds the bridge. The bridge also accelerated socioeconomic growth in the area, promoting rapid urban growth in Cixi County between 2002 and 2009. Overall, the Hangzhou Bay Bridge is an important driver of urban growth in Cixi County, and policy suggestions for sustainable urban growth should be adopted in the future.

    Full Text Available Abstracts are the same as lists: One notices right away when something is missing. I warn the reader that the text I present here wants to capture the overall sense, but she knows that here and there gaps and simplifications are unavoidable and make this task difficult. The reader is aware of it not only because it is any abstract’s destiny, but because a map which is the same size as the territory represented does not go anywhere. It has to necessarily be something else than the territory. Thus, this abstract is something other than the thesis to which it refers. In this text that follows I will discuss the platform where I deployed the instances that shaped my research. Secondly, I will refer to two of the several counter-intuitions that populate my thesis in relation to my view on the issue of sustainability, namely, to patience and perseverance in the sustainable future I oppose the presentist impatience of the sustainable instant and, at the end of this section, I will briefly discuss relational urban sustainability, specifically, the normative framework or, if you will, the vindication of control as an instance for sustainability. Third, I will offer some conclusions of my work.

  10. Sustainable Construction for Urban Infill Development Using Engineered Massive Wood Panel Systems

    Directory of Open Access Journals (Sweden)

    Steffen Lehmann

    2012-10-01

    Full Text Available Prefabricated engineered solid wood panel construction systems can sequester and store CO2. Modular cross-laminated timber (CLT, also called cross-lam panels form the basis of low-carbon, engineered construction systems using solid wood panels that can be used to build residential infill developments of 10 storeys or higher. Multi-apartment buildings of 4 to 10 storeys constructed entirely in timber, such as recently in Europe, are innovative, but their social and cultural acceptance in Australia and North America is at this stage still uncertain. Future commercial utilisation is only possible if there is a user acceptance. The author is part of a research team that aims to study two problems: first models of urban infill; then focus on how the use of the CLT systems can play an important role in facilitating a more livable city with better models of infill housing. Wood is an important contemporary building resource due to its low embodied energy and unique attributes. The potential of prefabricated engineered solid wood panel systems, such as CLT, as a sustainable building material and system is only just being realised around the globe. Since timber is one of the few materials that has the capacity to store carbon in large quantities over a long period of time, solid wood panel construction offers the opportunity of carbon engineering, to turn buildings into ‘carbon sinks’. Thus some of the historically negative environmental impact of urban development and construction can be turned around with CLT construction on brownfield sites.

    Cities in Asian developing countries experience rapid transformation in urban morphology and energy consumption, which correspondingly affects urban climate. Weather Research and Forecasting (WRF) Model coupled with improved single-layer urban canopy model incorporating realistic distribution of urban parameters and anthropogenic heat emission (AHE) in the tropic Jakarta Greater Area was conducted. Simulation was conducted during the dry months from 2006 to 2015 and agreed well with point and satellite observation. The same technology coupled with pseudo global warming (PGW) method based on representative concentration pathways (RCP) scenario 2.6 and 8.5 was conducted to produce futuristic climate condition in 2050. Projected urban morphology and AHE in 2050s were constructed using regional urban growing model with shared socioeconomic pathways (SSP) among its inputs. Compact future urban configuration, based on SSP1, was coupled to RCP2.6. Unrestrained future urban configuration, based on SSP3, was coupled to RCP8.5. Results show that background warming from RCP 2.6 and 8.5 will increase background temperature by 0.55°C and 1.2°C throughout the region, respectively. Future projection of urban sprawl results to an additional 0.3°C and 0.5°C increase on average, with maximum increase of 1.1°C and 1.3°C due to urban effect for RCP2.6/compact and RCP8.5/unrestrained, respectively. Higher moisture content in urban area is indicated in the future due to higher evaporation. Change in urban roughness is likely affect slower wind velocity in urban area and sea breeze front inland penetration the future compare with current condition.

    Alberti, M.; Graumlich, L. J.; Frumkin, H.; Friedman, D.

    2012-12-01

    A sustainable human future requires both healthy ecosystems and communities in which people thrive, with opportunities for health, well-being, happiness, economic prosperity, and equity. To make progress towards this goal, two largely disparate communities of scholars and practitioners must come together: sustainability science needs to be integrated with the sciences of human health and well-being. The opportunity for such integration is particularly ripe for urbanizing regions which not only dominate energy and resource use but also increasingly represent the human habitat. We present a conceptual framework that integrates sustainability science with the sciences of human health and well-being to explicitly articulate testable hypotheses on the relationships between humans and their habitat. We are interested in human behaviors and metrics of health and well-being in relationship to the characteristics of the built environment at various scales from buildings to metro regions. Focusing on the U.S. Pacific Northwest (PNW) as a testbed, we are building on our current empirical studies on urban sprawl and ecosystem function including biodiversity, air quality, hydrological, biogeochemical, and human health to develop formal hypotheses on how alternative urban design and development patterns may influence health outcomes and well-being. The PNW is an ideal setting for this work because of the connected metropolitan areas within a region characterized by a spectacular diversity of aquatic and terrestrial ecosystems and deeply held cultural and political aspirations towards sustainability. The framework also highlights opportunities for translation of knowledge to practice in the design and planning of built environments. For example, understanding these associations is critical to assessing tradeoffs in design and planning strategies and exploring potential synergies that optimize both sustainability and human well-being. In complex systems such as cities, managers

    The City will always grow and develop along with the increasing number of population which affect more demands of building space in the city. Thoserequirements of development can be done by the government, the private sector or by the individual sectors, but it needs to follow the ordinance which is set in the city plan to avoid the adverse negative impact in the future. The problems are if the monitored development in the city is like Jakarta - Indonesia, which have an area of 661 square kilometres compared with the limitation of government employee source. Therefore, it is important to advancing the new tools to monitor the development of the city, due to the large development area and the limitation of source. This research explores the using of Low-altitude UAV (Unmanned Aerial Vehicle) combined with photogrammetry techniques - a new rapidly developing technology - to collect as-built building development information in real time, cost-effective and efficient manner. The result of this research explores the possibility of using the UAV in sustainable urban development control and it can detect the anomalies of the development.

    2013-12-01

    Urbanization is occurring at an accelerating rate against a backdrop of the numerous other globally significant environmental changes that are the hallmark of the Anthropocene. Thus an understanding of the environmental impacts of urbanization must recognize the multiscalar context of other environmental changes. Cities are focal points of human population, production, and consumption, including the generation of waste and most of the critical emissions to the atmosphere. They are highly modified and dominated by built structure. They are generally depauperate of species and harbor their own microclimates and hot spots of pollutants. But they also are centers of human creative activities, and in that capacity may provide platforms for the transition to a more sustainable world. A view of the city, a complex social-technological-ecological system, as both driver and responder to these multiple stressors is key to developing appropriate conceptual frameworks for understanding urban ecosystem change. The convergence of global environmental change, including climate change, and worldwide urbanization presents numerous challenges for sustainability that are manifest at global, regional, and local scales. This presentation will explore the current reality and future prospects for resilience of cities and, more specifically, urban water systems, to extant and changing stressors at these three scales. At the global scale, challenges of supplying water for three billion new urban residents in the coming decades are explored through a geography of water availability, quality, and accessibility. At regional scales, I highlight differences in solutions to climate change-related challenges that derive from geophysical and socioecological gradients. And, at the local scale, blended technological and ecological solutions to the challenges of urban stormwater and the 'new normal' are discussed, based on a case study in an arid urban ecosystem.

  6. Feeling lucky? Using search engines to assess perceptions of urban sustainability

    International Nuclear Information System (INIS)

    Keirstead, James

    2009-01-01

    The sustainability of urban environments is an important issue at both local and international scales. Indicators are frequently used by decision-makers seeking to improve urban performance but these metrics can be dependent on sparse quantitative data. This paper explores the potential of an alternative approach, using an internet search engine to quickly gather qualitative data on the key attributes of cities. The method is applied to 21 world cities and the results indicate that, while the technique does shed light on direct and indirect aspects of sustainability, the validity of derived metrics as objective indicators of long-term sustainability is questionable. However the method's ability to provide subjective short-term assessments is more promising and it could therefore play an important role in participatory policy exercises such as public consultations. A number of promising technical improvements to the method's performance are also highlighted

    It is generally agreed that the governmental authorities should actively encourage the development of an efficient framework of information and communication technology initiatives so as to advance and promote sustainable development and planning strategies. This paper presents a prototype Information System for public administration which was designed to facilitate public management and decision making for sustainable development and planning. The system was developed by using several programming languages and programming tools and also a Database Management System (DBMS) for storing and managing urban data of many kinds. Furthermore, geographic information systems were incorporated into the system in order to make possible to the authorities to deal with issues of spatial nature such as spatial planning. The developed system provides a technology based management of geospatial information, environmental and crime data of urban environment aiming at improving public decision making and also at contributing to a more efficient sustainable development and planning.

    As the 21st century, known for knowledge information era, many industrial infrastructures built as part of the 20th century urban development have been devastated functionally and new alternatives for them have been demanded nowadays. This study aims to discuss the strategies used in the design proposals of the International Competition for ‘Seoullo 7017 Project’, which was recently completed in May 2017, based on the sustainability of the deteriorate infrastructure as urban park. Through the competition brief, each proposal is analysed against the competition brief and the more generic approaches on the adaptive reuse of infrastructure are proposed. By examining the case in Korea, it is expected to explore the possibilities for the sustainability of abandoned infrastructure through adapting reuse as urban park in Korea, to propose design strategies that can be applied to the future adaptive use of deteriorated infrastructure in Korea, and to provide broader academic base to related works.

  9. Encountering Urbanization on Jersey: Development, Sustainability, and Spatiality in a Small Island Setting

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available On the island of Jersey, the success of local industries including agriculture, tourism, and financial services has helped grow the population of permanent residents, contract workers, seasonal workers, and short-term tourists. As a result, between 1950 and 2015 the island’s population nearly doubled from about 55,000 to 100,000, and, consequently, the landscape has undergone much urban development, not only in and around the parish capital of St Helier, but also in varying degrees in each of the island’s other parishes. During this period of population growth, the island’s urbanization has been framed within a context of developing the island’s industries on the one hand, yet sustaining the island’s unique environment on the other. After all, one of the main qualities of Jersey that has helped its tourism industry has been its ability to maintain characteristics of the island in a context of population growth and increased resource restraints. Using a method of critical inquiry of primary and secondary sources, this article foregrounds how the geographically small island of Jersey has encountered urbanization, particularly in the decades following the Second World War. The discussion illustrates some of the consequences for islanders and how development and sustainability as an assemblage of interconnected practices and perceptions have helped craft a distinct environment for the island that contributes to its local character. The article shows that inward migration flows have led to a locally-defined urbanization, which has resulted in a continually growing population and a type of urban island lure. For the field of Island Studies, a study of Jersey’s locally-defined urbanization sheds light on how urban development and sustainability consciousness is characterized and practised on this particular small island in an era that sees it especially dependent on the finance and tourism industries.

  10. Futures of global urban expansion: uncertainties and implications for biodiversity conservation

    Urbanization will place significant pressures on biodiversity across the world. However, there are large uncertainties in the amount and location of future urbanization, particularly urban land expansion. Here, we present a global analysis of urban extent circa 2000 and probabilistic forecasts of urban expansion for 2030 near protected areas and in biodiversity hotspots. We estimate that the amount of urban land within 50 km of all protected area boundaries will increase from 450 000 km2 circa 2000 to 1440 000 ± 65 000 km2 in 2030. Our analysis shows that protected areas around the world will experience significant increases in urban land within 50 km of their boundaries. China will experience the largest increase in urban land near protected areas with 304 000 ± 33 000 km2 of new urban land to be developed within 50 km of protected area boundaries. The largest urban expansion in biodiversity hotspots, over 100 000 ± 25 000 km2, is forecasted to occur in South America. Uncertainties in the forecasts of the amount and location of urban land expansion reflect uncertainties in their underlying drivers including urban population and economic growth. The forecasts point to the need to reconcile urban development and biodiversity conservation strategies.

    2016-10-01

    Intensive urbanization is swallowing municipal green areas which causes intensification of erosion, decrease in biodiversity and permanent fragmentation of habitats. In the face of these changes, a risk of irreversible damages to urban ecosystems is growing. That is why planning of solutions within the framework of Green Urbanism in metropolitan areas inhabited by over 55% of the global population is of extraordinary importance. The task of the paper is to present patterns of the Green Urbanism using selected examples of metropolitan areas as case studies. The main goal of the research is to make comparison between GU practices in different countries, in various spatial settings. The principles of triple zero framework: zero fossil-fuel energy use, zero waste, zero emissions (from low-to-no-carbon emissions) introduce not only the contemporary trends in theoretical urban planning but are dictated by practical considerations to create a healthy environment for a healthy society with a minimized environmental footprint. The research results help to identify Green Urbanism techniques used for multiple functions, including ecological, recreational, cultural, aesthetic and other uses and present opportunities for implementation of Green Urbanism solutions in metropolitan areas. To achieve healthier society and environment, highly congested and polluted cities have to be recreated through working with the existing landscape, topography and natural resources particular to the site.

  15. BRIDGING OUTDOOR AND INDOOR ENVIRONMENTAL SIMULATION FOR ASSESSING AND AIDING SUSTAINABLE URBAN NEIGHBOURHOOD DESIGN

    Directory of Open Access Journals (Sweden)

    Chengzhi Peng

    2012-11-01

    Full Text Available Urban dwellers in cities located in hot-arid or hothumid regions have greater needs to live in between outdoor and indoor environments. The sustainability of urban building design in these regions cannot be fully assessed by indoor environmental simulation not taking into account the microclimatic factors of the surrounding urban neighbourhood. We find that the current suites of outdoor and indoor simulation software do not connect with each other to give us a holistic understanding of both outdoor and indoor simulation results. This paper reports on our current development of a methodological framework for bridging the current gap between outdoor and indoor environmental simulation. Our objective is that assessment of sustainability at an urban neighbourhood level can be carried out more holistically, and hence achieving more valid environmental simulations from an urban  dwelling point of view. The outdoor-indoor coupling methodology is currently modelled on a digital work flow among three key software platforms: (1 ENVImet for urban neighbourhood outdoor simulation, (2 Ecotect for building indoor simulation, (3 uCampus for combined outdoor-indoor 3D visualisation modelling of an entire urban neighbourhood including its individual buildings. A case study of a new neighbourhood development proposed for New Cairo is presented to demonstrate how indoor environmental simulation can be grounded on outdoor environmental simulation of the urban neighbourhood. Graphical outputs from this outdoorindoor coupling approach to neighbourhood simulation can be further brought together onto a Web-based 3D virtual reality modelling platform to enable wider accessibility.

    Selection of treatment technologies without considering the environmental, economic and social factors associated with each geographical context risks the occurrence of negative impacts that were not properly foreseen, working against the sustainable performance of the technology. The principal aim of this study was to evaluate 12 technologies for decentralized treatment of domestic wastewater applicable to peri-urban communities using sustainability approaches and, at the same time, continuing a discussion about how to address a more integrated assessment of overall sustainability. For this, a set of 13 indicators that embody the environmental, economic and social approach for the overall sustainability assessment were used by means of a target plot diagram as a tool for integrating indicators that represent a holistic analysis of the technologies. The obtained results put forward different degrees of sustainability, which led to the selection of: septic tank+land infiltration; up-flow anaerobic reactor+high rate trickling filter and septic tank+anaerobic filter as the most sustainable and attractive technologies to be applied in peri-urban communities, according to the employed indicators.

  17. Integrative evaluation for sustainable decisions of urban wastewater system management under uncertainty

    2017-12-01

    With sustainable development as their overarching goal, urban wastewater system (UWS) managers need to take into account multiple social, economic, technical and environmental facets related to their decisions. In this complex decision-making environment, uncertainty can be formidable. It is present both in the ways the system is interpreted stochastically, but also in its natural ever-shifting behavior. This inherent uncertainty suggests that wiser decisions would be made under an adaptive and iterative decision-making regime. No decision-support framework has been presented in the literature to effectively addresses all these needs. The objective of this work is to describe such a conceptual framework to evaluate and compare alternative solutions for various UWS challenges within an adaptive management structure. Socio-economic aspects such as externalities are taken into account, along with other traditional criteria as necessary. Robustness, reliability and resilience analyses test the performance of the system against present and future variability. A valuation uncertainty analysis incorporates uncertain valuation assumptions in the decision-making process. The framework is demonstrated with an application to a case study presenting a typical problem often faced by managers: poor river water quality, increasing population, and more stringent water quality legislation. The application of the framework made use of: i) a cost-benefit analysis including monetized environmental benefits and damages; ii) a robustness analysis of system performance against future conditions; iii) reliability and resilience analyses of the system given contextual variability; and iv) a valuation uncertainty analysis of model parameters. The results suggest that the installation of bigger volumes would give rise to increased benefits despite larger capital costs, as well as increased robustness and resilience. Population numbers appear to affect the estimated benefits most, followed by

    Today, urban agriculture is one of the most widely used sustainability strategies to improve the metabolism of a city. Schools can play an important role in the implementation of sustainability master plans, due their socio-educational activities and their cohesive links with families; all key elements in the development of urban agriculture. Thus, the main objective of this research is to develop a procedure, in compact cities, to assess the potential installation of rooftop greenhouses (RTGs) in schools. The generation of a dynamic assessment tool capable of identifying and prioritizing schools with a high potential for RTGs and their eventual implementation would also represent a significant factor in the environmental, social, and nutritional education of younger generations. The methodology has four-stages (Pre-selection criteria; Selection of necessities; Sustainability analysis; and Sensitivity analysis and selection of the best alternative) in which economic, environmental, social and governance aspects all are considered. It makes use of Multi-Attribute Utility Theory and Multi-Criteria Decision Making, through the Integrated Value Model for Sustainability Assessments and the participation of two panels of multidisciplinary specialists, for the preparation of a unified sustainability index that guarantees the objectivity of the selection process. This methodology has been applied and validated in a case study of 11 schools in Barcelona (Spain). The social perspective of the proposed methodology favored the school in the case-study with the most staff and the largest parent-teacher association (social and governance indicators) that obtained the highest sustainability index (S11); at a considerable distance (45%) from the worst case (S3) with fewer school staff and parental support. Finally, objective decisions may be taken with the assistance of this appropriate, adaptable, and reliable Multi-Criteria Decision-Making tool on the vertical integration and

    Urban areas in historic cities resemble a living organism that evolves in parallel to social transformation processes, shaping the material substrate that expresses identity and collective memory. In the twenty-first century, exponential population growth, globalization and the information society have resulted in many of these socio-economic processes accelerating, with consequences that we are not yet able to discern in their entirety. In this context, cities need to adapt to the general dynamics of urban development by incorporating the environmental, economic and social aspects of the "sustainability paradigm". With good planning, urban heritage is a key sustainable resource that needs promoting as part of the existing territorial competitiveness in a scenario marked by an increase in rivalry between cities. This requires the development of a conceptual framework that, based on a global, holistic and integrative approach, covers equity and social justice, respect for human rights, the gender perspective, public health and environmental quality, among other aspects. In this sense, the purpose of this paper is to study the concept of landscape applied to urban planning in greater depth, paying special attention to the analysis of the notion of Historic Urban Landscapes from a critical point of view, since the economic pressures arising from the reality of today's globalized world pose a serious threat that hinders their custody and protection, complicating this new comprehensive approach: how to bring this new systemic and transversal concept to the current regulatory framework in order to achieve real legal protection and effective governance models in urban areas? What should be the acceptable limits to ensure that "managing this change" does not result in public spaces being at the service of the interests of financial capitalism? These, along with many other questions, make the work of the professionals in charge of urban conservation more challenging in

    Sustainable development has become a central perspective in environmental strategies around the world. It is clear that neither governments nor businesses have the capability to bring about sustainability on their own. Therefore, collaboration has emerged as a central concept. At the same time it is obvious that someone has to take the lead in the development towards sustainability. This book focuses on different forms of collaboration emerging between various actors. The objective of the book is to more systematically explore the different roles and relationships between partnership and leadership. Basically, both partnership and leadership can be seen in a positive and negative way: for example, as far as partnership is concerned, we can assume that the path towards sustainability can be paved by parties coming together, taking some initiative collaborating. On the opposite, partnership and consensus-based decisions can be seen as an obstacle to foster radical changes in production and consumption patterns. Similarly, leadership can be seen as an obstacle to sustainable development if leaders form close circles and are not willing to share experiences with other actors; but leadership could also be considered as an important element to keep concepts and practices forward. The book holds this double perspective: explaining, mapping and analyzing different goals/formats/methods of more and less collaborative approaches, but at the same time taking a critical approach to the theme by understanding related risks, effects, prospects and corrective actions. Next to a conceptual part, the book brings together case-studies from around the world. The focus is in describing and understanding various formats of collaboration and critically evaluating its effects and prospects. A concluding chapter discusses the role of partnership and leadership in realizing various levels of environmental innovations: optimization and re-design, that usually affect only a small part of the

    Full Text Available Terra Preta Sanitation (TPS plays a key role in sustainable sanitation (SuSan and in the sustainable management of resources such as water, energy, soil (agriculture, liquid and solid organic waste streams as well as in the development of sustainable urban environment and infrastructure systems. This paper discusses the advantages of, and requirements for, SuSan systems, focusing on TPS. Case studies showing the stepwise extension and re-development of conventional sanitation systems (CSS using TPS technologies and system approaches are presented and discussed. Decentralized TPS systems integrated in sustainable urban resource management were implemented in the German cities of Hamburg and Berlin. The compilation of best practice examples and findings using the newest TPS systems illustrates the immense potential of this approach for the transformation from conventional to SuSan systems. For this purpose, the potential savings of drinking water resources and the recycling potential of nutrient components are quantified. The results strongly suggest the need to encourage the development and application of innovative decentralized sanitation technologies, urban infrastructures, and resource management systems that have TP as a key component.

    Full Text Available The construction and service of urban infrastructure systems and buildings involves immense resource consumption. Cities are responsible for the largest component of global energy, water, and food consumption as well as related sewage and organic waste production. Due to ongoing global urbanization, in which the largest sector of the global population lives in cities which are already built, global level strategies need to be developed that facilitate both the sustainable construction of new cities and the re-development of existing urban environments. A very promising approach in this regard is the decentralization and building integration of environmentally sound infrastructure systems for integrated resource management. This paper discusses such new and innovative building services engineering systems, which could contribute to increased energy efficiency, resource productivity, and urban resilience. Applied research and development projects in Germany, which are based on integrated system approaches for the integrated and environmentally sound management of energy, water and organic waste, are used as examples. The findings are especially promising and can be used to stimulate further research and development, including economical aspects which are crucial for sustainable urban (re-development.

    2016-01-01

    In the wake of Hurricane Sandy and other recent extreme events, urban coastal communities in the northeast region of the United States are beginning or stepping up efforts to integrate climate adaptation and resilience into long-term coastal planning. Natural and nature-based shoreline strategies have emerged as essential components of coastal resilience and are frequently cited by practitioners, scientists, and the public for the wide range of ecosystem services they can provide. However, there is limited quantitative information associating particular urban shoreline design strategies with specific levels of ecosystem service provision, and research on this issue is not always aligned with decision context and decision-maker needs. Engagement between the research community, local government officials and sustainability practitioners, and the non-profit and private sectors can help bridge these gaps. A workshop to bring together these groups discussed research gaps and challenges in integrating ecosystem services into urban sustainability planning in the urban northeast corridor. Many themes surfaced repeatedly throughout workshop deliberations, including the challenges associated with ecosystem service valuation, the transferability of research and case studies within and outside the region, and the opportunity for urban coastal areas to be a focal point for education and outreach efforts related to ecosystem services.

    Full Text Available Often centralized water supply, sanitation and solid waste services struggle to keep up with the rapid expansion of urban areas. The peri-urban areas are at the forefront of this expansion and it is here where decentralized technologies are increasingly being implemented. The introduction of decentralized technologies allows for the development of new opportunities that enable the recovery and reuse of resources in the form of water, nutrients and energy. This resource-oriented management of water, nutrients and energy requires a sustainable system aimed at low resource use and high recovery and reuse rates. Instead of investigating each sector separately, as has been traditionally done, this article proposes and discusses a concept that seeks to combine the in- and outflows of the different sectors, reusing water and other liberated resources where possible. This paper shows and demonstrates examples of different types of sustainable technologies that can be implemented in the peri-urban areas of Mexico City [rainwater harvesting, EcoSan and biofiltros (small constructed wetlands, and (vermi-composting]. An innovative participatory planning method, combining scenario development with a participatory planning workshop with key stakeholders, was applied and resulted in three concept scenarios. Specific technologies were then selected for each concept scenario that the technical feasibility and applicability was assessed. Following this, the resulting resource flows (nutrients, water and energy were determined and analyzed. The results show that decentralized technologies not only have the potential to deliver adequate water supply, sanitation and solid waste services in peri-urban areas and lessen environmental pollution, but also can recover significant amounts of resources thereby saving costs and providing valuable inputs in, for instance, the agricultural sector.
