what are five responses to urban sustainability challenges?

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. Right? Urban sustainability strategies and efforts must stay within planetary boundaries,1 particularly considering the urban metabolism, constituted by the material and energy flows that keep cities alive (see also Box 3-1) (Burger et al., 2012; Ferro and Fernndez, 2013). This type of information is critically important to develop new analyses to characterize and monitor urban sustainability, especially given the links between urban places with global hinterlands. 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). 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). How many categories are there in the AQI? City leaders must move quickly to plan for growth and provide the basic services, infrastructure, and affordable housing their expanding populations need. . Free and expert-verified textbook solutions. Firstly, we focused on the type of the policy instrument, the challenge it wants to address, as well as its time horizon. Wrong! There is a general ignorance about. Two environmental challenges to urban sustainability are water quality and air quality. Do you enjoy reading reports from the Academies online for free? All different types of waste must be properly managed in cities. Therefore, urban sustainability will require making explicit and addressing the interconnections and impacts on the planet. Without paying heed to finite resources, urban sustainability may be increasingly difficult to attain depending on the availability and cost of key natural resources and energy as the 21st century progresses (Day et al., 2014, 2016; McDonnell and MacGregor-Fors, 2016; Ramaswami et al., 2016). A summary of major research and development needs is as follows. The use of a DPSIR model posits an explicit causality effect between different actors and consequences and ensures exhaustive coverage of the phenomena contained in the model (Ferro and Fernandez, 2013). The ecological footprint of cities is measured by the number of people in a city and how much they're consuming. Urban Development Home. Health equity is a crosscutting issue, and emerging research theme, in urban sustainability studies. Big Idea 2: IMP - How are the attitudes, values, and balance of power of a population reflected in the built landscape? Ultimately, the goal of urban sustainability is to promote and enable the long-term well-being of people and the planet, yet doing so requires recognition of the biophysical constraints on all human and natural systems, as well as the acknowledgment that urban sustainability is multiscale and multidimensional, both encompassing and transcending urban jurisdictions. Urban sustainability requires the involvement of citizens, private entities, and public authorities, ensuring that all resources are mobilized and working toward a set of clearly articulated goals. Water resources in particular are at a greater risk of depletion due to increased droughts and floods. For the APHG Exam, remember these six main challenges! Urban Development. Discriminatory practices in the housing market over many decades have created racial segregation in central cities and suburbs. 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. Turbidity is a measure of how ___ the water is. 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). 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). A description of each of these phases is given below. More regulation and penalties can assist with waste management, but many countries, both developed and developing, struggle with this. See our explanation on Urban Sustainability to learn more! Generally, rural areas experience more levels of pollution than urban areas. There is the matter of urban growth that, if unregulated, can come in the form of suburban sprawl. Third, the critical task of developing finance models to support urban sustainability action requires urgent attention. Urban Development Overview - World Bank As simple and straightforward as this may sound, the scale argument encompasses more than spatial scaleit is composed of multiple dimensions and elements. 3 Clark, C. M. 2015. 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. There is a need to go beyond conventional modes of data observation and collection and utilize information contributed by users (e.g., through social media) and in combination with Earth observation systems. Developing new signals of urban performance is a crucial step to help cities maintain Earths natural capital in the long term (Alberti, 1996). How does air pollution contribute to climate change? Can a city planner prepare for everything that might go wrong, but still manage to plan cities sustainably? Meeting the challenges of planetary stewardship demands new governance solutions and systems that respond to the realities of interconnectedness. For example, in order to ensure that global warming remains below two degrees Celsius, the theoretical safe limit of planetary warming beyond which irreversible feedback loops begin that threaten human health and habitat, most U.S. cities will need to reduce GHG emissions 80 percent by 2050. Such limits can be implemented through local authorities guidelines and regulations in planning and regulating the built environment, e.g., guidelines and regulations pertaining to building material production, construction, building design and performance, site and settlement planning, and efficiency standards for appliances and fixtures. Efforts have been made by researchers and practitioners alike to create sets of indicators to assist in measuring and comparing the sustainability of municipalities, but few thresholds exist, and those that do often seem unattainable to municipal leaders. View our suggested citation for this chapter. Finally, the greater challenge of overpopulation from urban growth must be addressed and responded to through sustainable urban development. 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. Measuring progress towards sustainable or unsustainable urban development requires quantification with the help of suitable sustainability indicators. Climate change overall threatens cities and their built infrastructure. True or false? Conceptually, the idea that there is an ecological footprint, and that sustainable cities are places that seek to minimize this footprint, makes great sense (Portney, 2002). 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. . The COVID-19 pandemic is likely to influence Europe's transition towards more environmentally sustainable urbanisation patterns for years to come. Stop procrastinating with our study reminders. 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. Create the most beautiful study materials using our templates. By 2045, the world's urban population will increase by 1.5 times to 6 billion. This will continue the cycle of suburban sprawl and car dependency. Cities in developed countries may create more waste due to consuming and discarding a greater amount of. Particulate matter, lead, ground level ozone, nitrogen oxide, sulfur oxide, carbon dioxide, and carbon monoxide. Energy use is of particular concern for cities, as it can be both costly and wasteful. 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. Each of these urban sustainability challenges comes with its own host of issues. 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). Complementary research showed that clean air regulations have reduced infant mortality and increased housing prices (Chay and Greenstone, 2005; EPA, 1999). Thus, urban sustainability cannot be limited to what happens within a single place. 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). (2014). Waste disposal and sanitation are growing problems as urban areas continue to grow. How can a city's ecological footprint be a challenge to urban sustainability? Cities have experienced an unprecedented rate of growth in the last decade. What are two environmental challenges to urban sustainability? 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. The transition to sustainable urban development requires both appropriate city management and local authorities that are aware of the implications posed by new urban sustainability challenges. 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. Globally, over 50% of the population lives in urban areas today. regional planning efforts, urban growth boundaries, farmland protection policies, greenbelts, and redevelopment of brownfields. Ultimately, the laws of thermodynamics limit the amount of useful recycling. Long-term policies and institutionalized activities that can promote greater equity can contribute to the future of sustainable cities. Sustainable urban development has its own challenges ranging from urban growth to environmental problems caused by climate change. However, many of these areas may be contaminated and polluted with former toxins and the costs of clean-up and redevelopment may be high. 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. Resources Cities need resources such as water, food and energy to be viable. How can the redevelopment of brownfields respond tourban sustainability challenges? Development, i.e., the meeting of peoples needs, requires use of resources and implies generation of wastes. Earn points, unlock badges and level up while studying. 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. AQI ranged 51-100 means the air quality is considered good. Indicates air quality to levels to members of the public. Poor resource management can not only affect residents in cities but also people living in other parts of the world. This could inadvertently decrease the quality of life for residents in cities by creating unsanitary conditions which can lead to illness, harm, or death. There are several responses to urban sustainability challenges that are also part of urban sustainable development strategies. 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. Getting an accurate picture of the environmental impacts of all human activity, including that of people working in the private sector, is almost impossible. Intensive urban growth can lead to greater poverty, with local governments unable to provide services for all people. Statement at NAS Exploratory Meeting, Washington, DC. Ready to take your reading offline? The article aims to identify the priority policy/practice areas and interventions to solve sustainability challenges in Polish municipalities, as well as . Cholera, typhoid, diarrhea, hepatitis A, and polio. The AQI range 151-200 is colored ____. Name some illnesses that poor water quality can lead to. Cities are not islands. How many goods are imported into and exported from a city is not known in practically any U.S. city. MyNAP members SAVE 10% off online. Fair Deal legislation and the creation of the GI Bill. 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. 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. The clean-up for these can be costly to cities and unsustainable in the long term. 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.
