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. Earn points, unlock badges and level up while studying. Thus, some strategies to manage communal resources, such as community-based, bottom-up approaches examined by Ostrom (2009a), may be more difficult to obtain in urban settings. Show this book's table of contents, where you can jump to any chapter by name. 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. These policies can assist with a range of sustainability policies, from providing food for cities to maintaining air quality and providing flood control. Some of the most polluted cities in the world are located in areas of high manufacturing and industrialization. Sustainable management of resources and limiting the impact on the environment are important goals for cities. Cities have experienced an unprecedented rate of growth in the last decade. Providing the data necessary to analyze urban systems requires the integration of different economic, environmental, and social tools. Cities have captured more than 80 percent of the globes economic activity and offered social mobility and economic prosperity to millions by clustering creative, innovative, and educated individuals and organizations. Cholera, typhoid, diarrhea, hepatitis A, and polio. However, air quality and water resources can be protected through proper quality management and government policy. The implementation of long-term institutional governance measures will further support urban sustainability strategies and initiatives. Wrong! The highest AQI range (at the level of concern of hazardous) means that air quality is extremely poor and poses dangerous health risks to all. This is to say, the analysis of boundaries gives emphasis to the idea of think globally, act locally., Healthy people-environment and human-environment interactions are necessary synergistic relationships that underpin the sustainability of cities. 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. What are some anthropogenic causes of air pollution? Some obstacles a sustainable city can face can range from urban growth to climate change effects. . More about Challenges to Urban Sustainability, Fig. 2 Urban Sustainability Indicators and Metrics, The National Academies of Sciences, Engineering, and Medicine, Pathways to Urban Sustainability: Challenges and Opportunities for the United States. For instance, over the past 50 years, many U.S. cities experienced unprecedented reductions in population, prominently driven by highly publicized perceptions that city environments are somehow innately unsafe. It's a monumental task for cities to undertake, with many influences and forces at work. Water resources in particular are at a greater risk of depletion due to increased droughts and floods. Particularly for developing countries, manufacturing serves as a very important economic source, serving contracts or orders from companies in developed countries. The DPSIR framework describes the interactions between society and the environment, the key components of which are driving forces (D), pressures (P) on the environment and, as a result, the states (S) of environmental changes, their impacts (I) on ecosystems, human health, and other factors, and societal responses (R) to the driving forces, or directly to the pressure, state, or impacts through preventive, adaptive, or curative solutions. In other words, the challenges are also the reasons for cities to invest in sustainable urban development. Understanding these interconnections within system boundaries, from urban to global, is essential to promote sustainability. These same patterns of inequality also exist between regions and states with poor but resource-rich areas bearing the cost of the resource curse (see also Box 3-3). In other words, the needs call for the study of cities as complex systems, including the processes at different scales, determining factors, and tipping points to avoid adverse consequence. Some promising models exist, such as MITs Urban Metabolism framework, that warrant further development (Ferro and Fernndez, 2013). This is a target that leading cities have begun to adopt, but one that no U.S. city has developed a sound strategy to attain. Thinking about cities as closed systems that require self-sustaining resource independence ignores the concepts of comparative advantage or the benefits of trade and economies of scale. The six main challenges to urban sustainability include: suburban sprawl, sanitation, air and water quality, climate change, energy use, and the ecological footprint of cities. Big Ideas: Big Idea 1: PSO - How do physical geography and resources impact the presence and growth of cities? 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. This lens is needed to undergird and encourage collaborations across many organizations that will enable meaningful pathways to urban sustainability. Washington, DC: The National Academies Press. However, many of these areas may be contaminated and polluted with former toxins and the costs of clean-up and redevelopment may be high. All of the above research needs derive from the application of a complex system perspective to urban sustainability. A set of standards that are required of water in order for its quality to be considered high. I. Meeting the challenges of planetary stewardship demands new governance solutions and systems that respond to the realities of interconnectedness. The future of urban sustainability will therefore focus on win-win opportunities that improve both human and natural ecosystem health in cities. Jump up to the previous page or down to the next one. Long-term policies and institutionalized activities that can promote greater equity can contribute to the future of sustainable cities. The unrestricted growthoutside of major urban areas with separate designations for residential, commercial, entertainment, and other services, usually only accessible by car. Sign up to highlight and take notes. Indeed, it is unrealisticand not necessarily desirableto require cities to be solely supported by resources produced within their administrative boundaries. How can sanitation be a challenge to urban sustainability? outside of major urban areas with separate designations for residential, commercial, entertainment, and other services, usually only accessible by car. The challenges to urban sustainability are also what motivate cities to be more sustainable. For the long-term success and resilience of cities, these challenges should serve as a current guide for current and future development. In this context, we offer four main principles to promote urban sustainability, each discussed in detail below: Principle 1: The planet has biophysical limits. How can greenbelts respond tourban sustainability challenges? What are five responses to urban sustainability challenges? 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. Do you enjoy reading reports from the Academies online for free? The AQI range 151-200 is colored ____. We choose it not because it is without controversy, but rather because it is one of the more commonly cited indicators that has been widely used in many different contexts around the world. Another kind of waste produced by businesses is industrial waste, which can include anything from gravel and scrap metal to toxic chemicals. Cities that want to manage the amount of resources they're consuming must also manage population increases. Urbanization is a global phenomenon with strong sustainability implications across multiple scales. Firstly, we focused on the type of the policy instrument, the challenge it wants to address, as well as its time horizon. It is beyond the scope of this report to examine all available measures, and readers are directed to any of the numerous reviews that discuss their relative merits (see, for example, uek et al., 2012; EPA, 2014a; Janetos et al., 2012; Wiedmann and Barrett, 2010; Wilson et al., 2007; The World Bank, 2016; Yale University, 2016). Poor resource management can not only affect residents in cities but also people living in other parts of the world. The results do show that humans global ecological footprint is already well beyond the area of productive land and water ecosystems available on Earth and that it has been expanding in the recent decades. It focuses on nine cities across the United States and Canada (Los Angeles, CA, New York City, NY, Philadelphia, PA, Pittsburgh, PA, Grand Rapids, MI, Flint, MI, Cedar Rapids, IA, Chattanooga, TN, and Vancouver, Canada), chosen to represent a variety of metropolitan regions, with consideration given to city size, proximity to coastal and other waterways, susceptibility to hazards, primary industry, and several other factors. If a city experiences overpopulation, it can lead to a high depletion of resources, lowering the quality of life for all. Meeting development goals has long been among the main responsibilities of urban leaders. (2009), NRC (2004), Pina et al. Environmental disasters are more likely to occur with greater intensity; buildings, streets, and facilities are more likely to be damaged or destroyed. In particular, the institutional dimension plays an important role in how global issues are addressed, as discussed by Gurr and King (1987), who identified the need to coordinate two levels of action: the first relates to vertical autonomythe citys relationship with federal administrationand the second relates to the horizontal autonomya function of the citys relationship with local economic and social groups that the city depends on for its financial and political support. Copyright 2023 National Academy of Sciences. To analyze the measures taken at an urban level as a response to the challenges posed by the pandemic (RQ1), we used a set of criteria. Based on feedback from you, our users, we've made some improvements that make it easier than ever to read thousands of publications on our website. Lars Reuterswrd, Mistra Urban Futures Five challenges For sustainable cities 1. ecological Footprint 2. ecosystem services and biodiversity 3. invest for sustainability 4. the good life 5. leadership and c ooperation sustainable infrastructure and consumption patterns Any urban sustainability strategy is rooted in place and based on a sense of place, as identified by citizens, private entities, and public authorities. View our suggested citation for this chapter. Extreme inequalities threaten public health, economic prosperity, and citizen engagementall essential elements of urban sustainability. What is the ideal pH for bodies of water? 3 Principles of Urban Sustainability: A Roadmap for Decision Making. This can include waste made by offices, schools, and shops. They found that while those companies lost almost 600,000 jobs compared with what would have happened without the regulations, there were positive gains in health outcomes. Every indicator should be connected to both an implementation and an impact statement to garner more support, to engage the public in the process, and to ensure the efficiency and impact of the indicator once realized. 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). Non-point source pollution is when the exact location of pollution can be located. There is the matter of urban growth that, if unregulated, can come in the form of suburban sprawl. Book Description This title includes a number of Open Access chapters. Upload unlimited documents and save them online. 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. For instance, domestic waste is household trash, usually generate from packaged goods. Regional cooperation is especially important to combat suburban sprawl; as cities grow, people will look for cheaper housing in surrounding rural and suburban towns outside of cities. Instead they provide a safe space for innovation, growth, and development in the pursuit of human prosperity in an increasingly populated and wealthy world (Rockstrm et al., 2013). Fill in the blank. ), as discussed in Chapter 2. It is also important to limit the use of resources that are harmful to the environment. As discussed by Bai (2007), although there are factors beyond local control, the main obstacles to bringing the global concerns onto the local level are the reflection of contradictory perceptions, concerns, interests, and priorities, rather than the scale of the issue. First, large data gaps exist. Have all your study materials in one place. 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). It nevertheless serves as an indicator for advancing thinking along those lines. Its 100% free. Science can also contribute to these pathways by further research and development of several key facets of urban areas including urban metabolism, threshold detection of indicators, comprehension of different data sets, and further exploration of decision-making processes linked across scales. Practitioners starting out in the field would be well served by adopting one or more of the best practice standards (e.g., United Nations Sustainable Development Goals, Urban Sustainability Directors Network Sustainability Tools for Assessing and Rating Communities, and International Organization for Standardization Sustainability Standards) rather than endeavoring to develop their own unique suite of metrics as their data would be more comparable between cities and would have some degree of external validity built in. Intensive urban growth can lead to greater poverty, with local governments unable to provide services for all people. European cities have been at the forefront of the crisis from the very beginning, not only bearing the worst impacts but also becoming key actors in advocating for a green and just recovery. Sustainable urban development has its own challenges ranging from urban growth to environmental problems caused by climate change. Fertilizers, pesticides, and insecticides. Measuring progress towards sustainable or unsustainable urban development requires quantification with the help of suitable sustainability indicators. Sustainable urban development, as framed under Sustainable Development Goal 11, involves rethinking urban development patterns and introducing the means to make urban settlements more inclusive, productive and environmentally friendly. Characterizing the urban metabolism constitutes a priority research agenda and includes quantification of the inputs, outputs, and storage of energy, water, nutrients, products, and wastes, at an urban scale. Lerne mit deinen Freunden und bleibe auf dem richtigen Kurs mit deinen persnlichen Lernstatistiken. Name three countries with poor air quality. Further, unpredictable timing and quantity of precipitation can both dry up growing crops or lead to flash floods. This is because without addressing these challenges, urban sustainability is not as effective. Only about 2 hectares (4.94 acres) of such ecosystems are available, however, for each person on Earth (with no heed to the independent requirements of other consumer species). 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. 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. Introduction. So Paulo Statement on Urban Sustainability: A Call to Integrate Our Responses to Climate Change, Biodiversity Loss, and Social Inequality . Principle 2: Human and natural systems are tightly intertwined and come together in cities. Very little information on the phases of urban processes exists, be it problem identification or decision making. Institutional scale plays an important role in how global issues can be addressed. How many goods are imported into and exported from a city is not known in practically any U.S. city. Classifying these indicators as characterizing a driver, a pressure, the state, the impact, or a response may allow for a detailed approach to be used even in the absence of a comprehensive theory of the phenomena to be analyzed. Poor waste management can lead to direct or indirect pollution of water, air, and other resources. The concept of planetary boundaries has been developed to outline a safe operating space for humanity that carries a low likelihood of harming the life support systems on Earth to such an extent that they no longer are able to support economic growth and human development . Urban governments are tasked with the responsibility of managing not only water resources but also sanitation, waste, food, and air quality. Pathways to Urban Sustainability: Challenges and Opportunities for the United States. A Review of Policy Responses on Urban Mobility" Sustainability 13, no. The ecological footprint of cities is measured by the number of people in a city and how much they're consuming. One challenge in the case of cities, however, is that many of these shared resources do not have definable boundaries such as land. Health impacts, such as asthma and lung disease. Thus, urban sustainability cannot be limited to what happens within a single place. The majority of natural resources in the world are consumed in cities. Without regional planning, rural and suburban towns will grow but will have a massive amount of commuters demanding greater highway access. A comprehensive strategy in the form of a roadmap, which incorporates these principles while focusing on the interactions among urban and global systems, can provide a framework for all stakeholders engaged in metropolitan areas, including local and regional governments, the private sector, and nongovernmental organizations, to enable meaningful pathways to urban sustainability.
