Commitment to sustainable development by city or municipal authorities means adding new goals to those that are their traditional concerns (McGranahan and Satterthwaite, 2003). The clean-up for these can be costly to cities and unsustainable in the long term. New Urban Sustainability Framework Guides Cities Towards a Greener Future Particulate matter, lead, ground level ozone, nitrogen oxide, sulfur oxide, carbon dioxide, and carbon monoxide. Not a MyNAP member yet? PDF Five Challenges - wwwwwfse.cdn.triggerfish.cloud Where possible, activities that offer co-occurring, reasonably sized benefits in multiple dimensions of sustainability should be closely considered and pursued as primary choices while managing tradeoffs. Restrictive housing covenants, exclusionary zoning, financing, and racism have placed minorities and low-income people in disadvantaged positions to seek housing and neighborhoods that promote health, economic prosperity, and human well-being (Denton, 2006; Rabin, 1989; Ritzdorf, 1997; Sampson, 2012; Tilley, 2006). The scientific study of environmental thresholds, their understanding, modeling, and prediction should also be integrated into early warning systems to enable policy makers to understand the challenges and impacts and respond effectively (Srebotnjak et al., 2010). Healthy human and natural ecosystems require that a multidimensional set of a communitys interests be expressed and actions are intentional to mediate those interests (see also Box 3-2). Fill in the blank. Urban governments are tasked with the responsibility of managing not only water resources but also sanitation, waste, food, and air quality. The task is, however, not simple. Ecological footprint calculations show that the wealthy one-fifth of the human family appropriates the goods and life support services of 5 to 10 hectares (12.35 to 24.70 acres) of productive land and water per capita to support their consumer lifestyles using prevailing technology. It must be recognized that ultimately all sustainability is limited by biophysical limits and finite resources at the global scale (e.g., Burger et al., 2012; Rees, 2012).A city or region cannot be sustainable if its principles and actions toward its own, local-level sustainability do not scale up to sustainability globally. Climate change, pollution, inadequate housing, and unsustainable production and consumption are threatening environmental justice and health equity across generations, socioeconomic strata, and urban settings. Here it is important to consider not only the impact on land-based resources but also water and energy that are embodied in products such as clothing and food. Third, the critical task of developing finance models to support urban sustainability action requires urgent attention. Book Description This title includes a number of Open Access chapters. How can air and water quality be a challenge to urban sustainability? 1 Planetary boundaries define, as it were, the boundaries of the planetary playing field for humanity if we want to be sure of avoiding major human-induced environmental change on a global scale (Rockstrm et al., 2009). Any urban sustainability strategy is rooted in place and based on a sense of place, as identified by citizens, private entities, and public authorities. Many of these class and cultural inequalities are the products of centuries of discrimination, including instances of officially sanctioned discrimination at the hands of residents and elected leaders (Fullilove and Wallance, 2011; Powell and Spencer, 2002). New sustainability indicators and metrics are continually being developed, in part because of the wide range of sustainability frameworks used as well as differences in spatial scales of interest and availability (or lack thereof) of data. Fine material produced in air pollution that humans can breathe in. Test your knowledge with gamified quizzes. The development of analysis to improve the sustainability of urbanization patterns, processes, and trends has been hindered by the lack of consistent data to enable the comparison of the evolution of different urban systems, their dynamics, and benchmarks. How many categories are there in the AQI? View our suggested citation for this chapter. Decision making at such a complex and multiscale dimension requires prioritization of the key urban issues and an assessment of the co-net benefits associated with any action in one of these dimensions. More regulation and penalties can assist with waste management, but many countries, both developed and developing, struggle with this. transportation, or waste. The key here is to be able to provide information on processes across multiple scales, from individuals and households to blocks and neighborhoods to cities and regions. Developing new signals of urban performance is a crucial step to help cities maintain Earths natural capital in the long term (Alberti, 1996). Indeed, often multiple cities rely on the same regions for resources. 11: 6486 . You're a city planner who has gotten all the support and funding for your sustainability projects. These goals do not imply that city and municipal authorities need be major providers of housing and basic services, but they can act as supervisors and/or supporters of private or community provision. Two environmental challenges to urban sustainability are water quality and air quality. In recent years, city-level sustainability indicators have become more popular in the literature (e.g., Mori and Christodoulou, 2012). Switch between the Original Pages, where you can read the report as it appeared in print, and Text Pages for the web version, where you can highlight and search the text. This task is complex and requires further methodological developments making use of harmonized data, which may correlate material and energy consumption with their socioeconomic drivers, as attempted by Niza et al. Big Idea 3: SPS - How are urban areas affected by unique economic, political, cultural, and environmental The continuous reassessment of the impact of the strategy implemented requires the use of metrics, and a DPSIR framework will be particularly useful to assess the progress of urban sustainability. 4, Example of a greenbelt in Tehran, Iran (https://commons.wikimedia.org/wiki/File:Tochal_from_Modarres_Expressway.jpg), by Kaymar Adl (https://www.flickr.com/photos/kamshots/), licensed by CC-BY-2.0 (https://creativecommons.org/licenses/by/2.0/deed.en). planetary boundaries do not place a cap on human development. Urban sustainability has been defined in various ways with different criteria and emphases, but its goal should be to promote and enable the long-term well-being of people and the planet, through efficient use of natural resources and production of wastes within a city region while simultaneously improving its livability, through social amenities, economic opportunity, and health, so that it can better fit within the capacities of local, regional, and global ecosystems, as discussed by Newman (1999). First, greater and greater numbers of people are living in urban areasand are projected to do so for the foreseeable future. For a pollutantthe sustainable rate of emission can be no greater than the rate at which that pollutant can be recycled, absorbed, or rendered harmless in its sink. Because urban systems connect distant places through the flows of people, economic goods and services, and resources, urban sustainability cannot be focused solely on cities themselves, but must also encompass places and land from which these resources originate (Seto et al., 2012). . I have highlighted what I see as two of the most interesting and critical challenges in sustainable urban development: understanding the 'vision' (or visions) and developing a deeper understanding of the multi-faceted processes of change required to achieve more sustainable cities. In this context, we offer four main principles to promote urban sustainability, each discussed in detail below: Principle 1: The planet has biophysical limits. This requirement applies to governance vertically at all levels of administration, from local to federal and international, and horizontally among various urban sectors and spaces. Right? The main five responses to urban sustainability challenges are regional planning efforts, urban growth boundaries, farmland protection policies, and greenbelts. Policies and cultural norms that support the outmigration, gentrification, and displacement of certain populations stymie economic and environmental progress and undermine urban sustainability (Fullilove and Wallace, 2011; Powell and Spencer, 2002; Williams, 2014). In an increasingly urbanized and globalized world, the boundaries between urban and rural and urban and hinterland are often blurred. Furthermore, the governance of urban activities does not always lie solely with municipal or local authorities or with other levels of government. To improve the threshold knowledge of sustainability indicators and their utility in defining an action strategy, it is necessary to have empirical tests of the performance and redundancy of these indicators and indicator systems.3 This is of increasing importance to policy makers and the public as human production and consumption put increased stress on environmental, economic, and social systems. All of the above research needs derive from the application of a complex system perspective to urban sustainability. Urban Development. Because an increasing percentage of the worlds population and economic activities are concentrated in urban areas, cities are highly relevant, if not central, to any discussion of sustainable development. Energy use is of particular concern for cities, as it can be both costly and wasteful. In discussing sustainability from a global perspective, Burger et al. Urban sustainability challenges 5. More than half the worlds population lives in urban areas, with the U.S. percentage at 80 percent. This briefing provides an initial overview of how the . In this regard, access . With poor quality, the health and well-being of residents can be jeopardized, leading again to possible illness, harm, or death. Wrong! Urban sprawl reduces available water catchment areas, agricultural lands and increases demand for energy. These can be sites where previous factories, landfills, or other facilities used to operate. According to the definition by Gurr and King (1987), the first relates to vertical autonomy, which is a function of the citys relationship with senior-level government. or use these buttons to go back to the previous chapter or skip to the next one. Climate, precipitation, soil and sediments, vegetation, and human activities are all factors of declining water quality. As climate change effects intensify extreme weather patterns, disturbances in water resources can occur. 2Abel Wolman (1965) developed the urban metabolism concept as a method of analyzing cities and communities through the quantification of inputswater, food, and fueland outputssewage, solid refuse, and air pollutantsand tracking their respective transformations and flows. These policies can assist with a range of sustainability policies, from providing food for cities to maintaining air quality and providing flood control. Institutional scale plays an important role in how global issues can be addressed. A strip mall is built along a major roadway. Introduction. If development implies extending to all current and future populations the levels of resource use and waste generation that are the norm among middle-income groups in high-income nations, it is likely to conflict with local or global systems with finite resources and capacities to assimilate wastes. It is crucial for city leaders to be aware of such perceptions, both true and artificial, and the many opportunities that may arise in directly addressing public concerns, as well as the risks and consequences of not doing so. For a nonrenewable resourcefossil fuel, high-grade mineral ores, fossil groundwaterthe sustainable rate of use can be no greater than the rate at which a renewable resource, used sustainably, can be substituted for it. Best study tips and tricks for your exams. Successful models exist elsewhere (such as British Columbia, Canadas, carbon tax), which can be adapted and scaled to support urban sustainability action across America. Furthermore, this studys findings cross-validate the findings of earlier work examining the recession-induced pollution reductions of the early 1980s. Stop procrastinating with our study reminders. This common approach can be illustrated in the case of urban food scraps collection where many cities first provided in-kind support to individuals and community groups offering collection infrastructure and services, then rolled out programs to support social norming in communities (e.g., physical, visible, green bins for residents to be put out at the curb), and finally banned organics from landfills, providing a regulatory mechanism to require laggards to act. As discussed by Bai (2007), the fundamental point in the scale argument is that global environmental issues are simply beyond the reach and concern of city government, and therefore it is difficult to tackle these issues at the local level. The overall ecological footprint of cities is high and getting higher. Taking the challenges forward. Urban sustainability is the goal of using resources to plan and develop cities to improve the social, economic, and environmental conditions of a city to ensure the quality of life of current and future residents. For the long-term success and resilience of cities, these challenges should serve as a current guide for current and future development. Sustainable management of resources and limiting the impact on the environment are important goals for cities. Some of the challenges that cities and . when only one kind of use or purpose can be built. In order to facilitate the transition toward sustainable cities, we suggest a decision framework that identifies a structured but flexible process that includes several critical elements (Figure 3-1). Commercial waste is generated by businesses, usually also in the form of an overabundance of packaged goods. What pollutants occur due to agricultural practices? It will require recognition of the biophysical and thermodynamic aspects of sustainability. There is evidence that the spatial distribution of people of color and low-income people is highly correlated with the distribution of air pollution, landfills, lead poisoning in children, abandoned toxic waste dumps, and contaminated fish consumption. High amounts of nutrients that lead to an algal bloom and prevents oxygen and light from entering the water. Water conservation schemes can then be one way to ensure both the quantity and quality of water for residents. Daly (2002) proposed three criteria that must be met for a resouce or process to be considered sustainable: Fiala (2008) pointed to two issues that can be raised regarding the ecological footprint method. 5. Examples of Urban Sustainability Challenges The results imply that poor air quality had substantial effects on infant health at concentrations near the U.S. Environmental Protection Agencymandated air quality standard and that roughly 1,300 fewer infants died in 1972 than would have in the absence of the Act. Poor resource management can not only affect residents in cities but also people living in other parts of the world.
