planetary boundaries do not place a cap on human development. True or false? Sustaining natural resources in the face of climate change and anthropogenic pressures is increasingly becoming a challenge in Africa [ 1, 2, 3, 4, 5, 6, 7 ]. It is also important to limit the use of resources that are harmful to the environment. What sources of urbanization can create water pollution? The task is, however, not simple. Second, cities exist as part of integrated regional and global systems that are not fully understood. 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. This is the first step to establish an urban sustainability framework consistent with the sustainability principles described before, which provide the fundamental elements to identify opportunities and constraints for different contexts found in a diversity of urban areas. Sustainable urban development has its own challenges ranging from urban growth to environmental problems caused by climate change. Poor resource management can not only affect residents in cities but also people living in other parts of the world. There is the issue, however, that economic and energy savings from these activities may suffer from Jevons Paradox in that money and energy saved in the ways mentioned above will be spent elsewhere, offsetting local efficiencies (Brown et al., 2011; Hall and Klitgaard, 2011). Reducing severe economic, political, class, and social inequalities is pivotal to achieving urban sustainability. Sustainable solutions are to be customized to each of the urban development stages balancing local constraints and opportunities, but all urban places should strive to articulate a multiscale and multipronged vision for improving human well-being. Transportation, industrial facilities, fossil fuels, and agriculture. By registering you get free access to our website and app (available on desktop AND mobile) which will help you to super-charge your learning process. In each parameter of sustainability, disruptions can only be withstood to a certain level without possible irreversible consequences. Ultimately, all the resources that form the base on which urban populations subsist come from someplace on the planet, most often outside the cities themselves, and often outside of the countries where the cities exist. In a kickoff event at UCLA's Royce Hall (see event video), Chancellor Gene Block will describe the ambitious project . 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). Part of the solution lies in how cities are planned, governed, and provide services to their citizens. If a city experiences overpopulation, it can lead to a high depletion of resources, lowering the quality of life for all. Earn points, unlock badges and level up while studying. The overall ecological footprint of cities is high and getting higher. Big Idea 3: SPS - How are urban areas affected by unique economic, political, cultural, and environmental Furthermore, the development of indicators should be supported with research that expresses the impact of the indicator. Inequitable environmental protection undermines procedural, geographic, and social equities (Anthony, 1990; Bullard, 1995). In recent years, city-level sustainability indicators have become more popular in the literature (e.g., Mori and Christodoulou, 2012). These goals generally include attracting new investment, improving social conditions (and reducing social problems), ensuring basic services and adequate housing, and (more recently) raising environmental standards within their jurisdiction. Cities that are serious about sustainability will seek to minimize their negative environmental impacts across all scales from local to global. These tools should provide a set of indicators whose political relevance refers both to its usefulness for securing the fulfillment of the vision established for the urban system and for providing a basis for national and international comparisons, and the metrics and indicators should be policy relevant and actionable. Cholera, typhoid, diarrhea, hepatitis A, and polio. 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). You're a city planner who has gotten all the support and funding for your sustainability projects. Water conservation schemes can then be one way to ensure both the quantity and quality of water for residents. or use these buttons to go back to the previous chapter or skip to the next one. Urban systems are complex networks of interdependent subsystems, for which the degree and nature of the relationships are imperfectly known. 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). Non-point source pollution is when the exact location of pollution can be located. 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. tourism, etc. Extra-urban impacts of urban activities such as ecological . 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. True or false? Ensuring urban sustainability can be challenging due to a range of social, economic, and environmental factors. of the users don't pass the Challenges to Urban Sustainability quiz! While urban areas can be centers for social and economic mobility, they can also be places with significant inequality, debility, and environmental degradation: A large proportion of the worlds population with unmet needs lives in urban areas. 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. unrestricted growth outside of major urban areas with separate designations for residential, commercial, entertainment, and other services, usually only accessible by car. 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. Poor waste management likewise can harm the well-being of residents through improper waste disposal. In practice, simply trying to pin down the size of any specific citys ecological footprintin particular, the ecological footprint per capitamay contribute to the recognition of its relative impacts at a global scale. Free and expert-verified textbook solutions. Urban sustainability challenges 5. Urbanization is a global phenomenon with strong sustainability implications across multiple scales. See our explanation on Urban Sustainability to learn more! Name three countries with poor air quality. One challenge in the case of cities, however, is that many of these shared resources do not have definable boundaries such as land. Consequently, what may appear to be sustainable locally, at the urban or metropolitan scale, belies the total planetary-level environmental or social consequences. What are some obstacles that a sustainable city faces? View our suggested citation for this chapter. How can air and water quality be a challenge to urban sustainability? This is because without addressing these challenges, urban sustainability is not as effective. The AQI range 151-200 is colored ____. Upload unlimited documents and save them online. This study provides direct and easily interpreted estimates of the air quality and infant health benefits of the 1970 Act. There is a general ignorance about. 5. How can energy use be a challenge to urban sustainability? ir quality and water resources can be protected through proper quality management and government policy. Poor resource management can not only affect residents in cities but also people living in other parts of the world. 2. Therefore, the elimination of these obstacles must start by clarifying the nature of the issue, identifying which among the obstacles are real and which can be handled by changing perceptions, concerns, and priorities at the city level. 3 Clark, C. M. 2015. UCLA will unveil plans on Nov. 15 designed to turn Los Angeles into a global model for urban sustainability. Principle 2: Human and natural systems are tightly intertwined and come together in cities. The challenges to urban sustainability are often the very same challenges that motivate cities to be more sustainable in the first place. Durable sustainability policies that transcend single leaders, no matter how influential, will also be necessary to foster reliable governance and interconnectedness over the long term for cities. Successful models exist elsewhere (such as British Columbia, Canadas, carbon tax), which can be adapted and scaled to support urban sustainability action across America. Cities in developed countries may create more waste due to consuming and discarding a greater amount of packaging. Furthermore, this studys findings cross-validate the findings of earlier work examining the recession-induced pollution reductions of the early 1980s. Particulate matter, lead, ground level ozone, nitrogen oxide, sulfur oxide, carbon dioxide, and carbon monoxide. The second is an understanding of the finite nature of many natural resources (or the ecosystems from which they are drawn) and of the capacities of natural systems in the wider regional, national, and international context to absorb or break down wastes. Urban sustainability requires durable, consistent leadership, citizen involvement, and regional partnerships as well as vertical interactions among different governmental levels, as discussed before. 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. 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. when only one kind of use or purpose can be built. Discriminatory practices in the housing market over many decades have created racial segregation in central cities and suburbs. Taking the challenges forward. Examples include smoke and dust. Bai (2007) points to threethe spatial, temporal, and institutional dimensionsand in each of these dimensions, three elements exist: scale of issues, scale of concerns, and scale of actions and responses. Urban governments are tasked with the responsibility of managing not only water resources but also sanitation, waste, food, and air quality. 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. The first is to consider the environmental impacts of urban-based production and consumption on the needs of all people, not just those within their jurisdiction. Although perfect class and economic equality is not possible, severe urban disparities should remain in check if cities are to realize their full potential and become appealing places of choice for multigenerational urban dwellers and new urban immigrants alike. The six main challenges to urban sustainability include: Other urban sustainability challenges include industrial pollution, waste management, and overpopulation. 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. Urban governments are tasked with the responsibility of managing not only water resources but also sanitation, waste, food, and air quality. How does air pollution contribute to climate change? Cities have experienced an unprecedented rate of growth in the last decade. Suburban sprawl is unrestricted growth outside of major urban areas with separate designations for residential, commercial, entertainment, and other services, usually only accessible by car. However, recent scientific analyses have shown that major cities are actually the safest areas in the United States, significantly more so than their suburban and rural counterparts, when considering that safety involves more than simply violent crime risks but also traffic risks and other threats to safety (Myers et al., 2013). There are different kinds of waste emitted in urban areas. Fill in the blank. Designing a successful strategy for urban sustainability requires developing a holistic perspective on the interactions among urban and global systems, and strong governance. Principle 3: Urban inequality undermines sustainability efforts. 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. A multiscale governance system that explicitly addresses interconnected resource chains and interconnected places is necessary in order to transition toward urban sustainability (Box 3-4). Development, i.e., the meeting of peoples needs, requires use of resources and implies generation of wastes. Without regional planning, rural and suburban towns will grow but will have a massive amount of commuters demanding greater highway access. Cities with a high number of manufacturing are linked with ____. Can a city planner prepare for everything that might go wrong, but still manage to plan cities sustainably? 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. Three elements are part of this framework: A DPSIR framework is intended to respond to these challenges and to help developing urban sustainability policies and enact long-term institutional governance to enable progress toward urban sustainability. Very little information on the phases of urban processes exists, be it problem identification or decision making. Providing the data necessary to analyze urban systems requires the integration of different economic, environmental, and social tools. This briefing provides an initial overview of how the . The main five responses to urban sustainability challenges are regional planning efforts, urban growth boundaries, farmland protection policies, and greenbelts. Big Idea 2: IMP - How are the attitudes, values, and balance of power of a population reflected in the built landscape? Another kind of waste produced by businesses is industrial waste, which can include anything from gravel and scrap metal to toxic chemicals. Moreover, because most cities are geographically separated from their resource base, it is difficult to assess the threat of resource depletion or decline. 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. Learn about and revise the challenges that some British cities face, including regeneration and urban sustainability, with GCSE Bitesize Geography (AQA). Given the relevance and impact of these constraints to the discussion of various pathways to urban sustainability, a further examination of these issues and their associated challenges are described in Appendix C (as well as by Day et al., 2014; Seto and Ramankutty, 2016; UNEP, 2012). Stop procrastinating with our study reminders. . Poor resource management can not only affect residents in cities but also people living in other parts of the world. City leaders must move quickly to plan for growth and provide the basic services, infrastructure, and affordable housing their expanding populations need. 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. Institutional scale plays an important role in how global issues can be addressed. Thus, urban sustainability cannot be limited to what happens within a single place. Improper waste disposal can lead to air, water, and soil pollution and contamination. Water resources in particular are at a greater risk of depletion due to increased droughts and floods. Cities have central roles in managing the planets resources sustainability (Seitzinger et al., 2012). urban sustainability in the long run. 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). Sustainability is a community concern, not an individual one (Pelletier, 2010). There are six main challenges to urban sustainability. Sustainable development can be implemented in ways that can both mitigate the challenges of urban sustainability and address the goals. 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. The ecological footprint of cities is measured by the number of people in a city and how much they're consuming. Everything you need for your studies in one place. Climate, precipitation, soil and sediments, vegetation, and human activities are all factors of declining water quality. Therefore, urban sustainability will require making explicit and addressing the interconnections and impacts on the planet. More regulation and penalties can assist with waste management, but many countries, both developed and developing, struggle with this. Some of the challenges that cities and . Finally, the greater challenge of overpopulation from urban growth must be addressed and responded to through sustainable urban development. This could inadvertently decrease the quality of life for residents in cities by creating unsanitary conditions which can lead to illness, harm, or death. In short, urban sustainability will require a reconceptualization of the boundaries of responsibility for urban residents, urban leadership, and urban activities. over time to produce the resources that the population consumes, and to assimilate the wastes that the population produces, wherever on Earth the relevant land and/or water is located. Some promising models exist, such as MITs Urban Metabolism framework, that warrant further development (Ferro and Fernndez, 2013). 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. There are several responses to urban sustainability challenges that are also part of urban sustainable development strategies. Ultimately, the laws of thermodynamics limit the amount of useful recycling. 4, Example of a greenbelt in Tehran, Iran. This discussion focuses on promoting a systems approachconnections, processes, and linkagesthat requires data, benchmarks, and guidance on what variables are relevant and what processes are most critical to understanding the relationships among the parts of the system. How can greenbelts respond tourban sustainability challenges? Meeting development goals has long been among the main responsibilities of urban leaders. 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. suburban sprawl, sanitation, air and water quality, climate change, energy use, and the ecological footprint of cities. These areas can both improve air quality, preserve natural habitats for animals, and allow for new recreational opportunities for residents. Discussions should generate targets and benchmarks but also well-researched choices that drive community decision making. Fig. 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). True or false? . Register for a free account to start saving and receiving special member only perks. and the second relates to horizontal autonomy, which is a function of the citys relationship with local economic and social groups that the city depends on for its financial and political support. Urban sustainability is a large and multifaceted topic. 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. Often a constraint may result in opportunities in other dimensions, with an example provided by Chay and Greenstone (2003) on the impact of the Clean Air Act amendments on polluting plants from 1972 and 1987. At its core, the concept of sustainable development is about reconciling development and environment (McGranahan and Satterthwaite, 2003). Farmland protection policies are policies that prevent the conversion of agricultural land to anything non-agricultural-related. (2015), and Rosado et al. Urban metabolism2 may be defined as the sum of the technical and socioeconomic processes that occur in cities, resulting in growth, production of energy, and elimination of waste (Kennedy et al., 2007). Currently, urban governance is largely focused on single issues such as water. These can be sites where previous factories, landfills, or other facilities used to operate. 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). By 2045, the world's urban population will increase by 1.5 times to 6 billion. First, large data gaps exist. Local decision making must have a larger scope than the confines of the city or region. 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. What are two environmental challenges to urban sustainability? 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). Making cities more resilient against these environmental threats is one of the biggest challenges faced by city authorities and requires urgent attention. Here we use the concept of ecological footprint, which has been proposed as an analytic tool to estimate the load imposed on the ecosphere by any specified human population (Berkowitz and Rees, 2003). Name some illnesses that poor water quality can lead to. The main five responses to urban sustainability challenges are regional planning efforts, urban growth boundaries, farmland protection policies, greenbelts, and redevelopment of brownfields. Specific strategies can then be developed to achieve the goals and targets identified. Some obstacles a sustainable city can face can range from urban growth to climate change effects. Feedback mechanisms that enable the signals of system performance to generate behavioral responses from the urban community at both the individual and institutional levels. Lack of regulation and illegal dumping are causes for concern and can lead to a greater dispersion of pollutants without oversight. Best study tips and tricks for your exams. What are the six main challenges to urban sustainability? All different types of waste must be properly managed in cities. Introduction. outside of major urban areas with separate designations for residential, commercial, entertainment, and other services, usually only accessible by car. This paper focuses on adaptive actions in response to WEF challenges as well as the environmental implications of these responses in Harare, Zimbabwe. The COVID-19 pandemic is likely to influence Europe's transition towards more environmentally sustainable urbanisation patterns for years to come. Much of the current information on urban areas is about stocks or snapshots of current conditions of a single place or location. Urban Development Home. 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). All rights reserved. Further, unpredictable timing and quantity of precipitation can both dry up growing crops or lead to flash floods. 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 . This means the air quality is at the level of concern of ____. A summary of major research and development needs is as follows. (2014). Over 10 million students from across the world are already learning smarter. 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. A large suburban development is built out in the countryside. Clustering populations, however, can compound both positive and negative conditions, with many modern urban areas experiencing growing inequality, debility, and environmental degradation. A practitioner could complement the adopted standard(s) with additional indicators unique to the citys context as necessary. 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.
