what are five responses to urban sustainability challenges?

. How can energy use be a challenge to urban sustainability? 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). Best study tips and tricks for your exams. However, some cities are making a much more concerted effort to understand the full range of the negative environmental impacts they produce, and working toward reducing those impacts even when impacts are external to the city itself. Stop procrastinating with our study reminders. The ecological footprint of cities is measured by the number of people in a city and how much they're consuming. 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. Waste disposal and sanitation are growing problems as urban areas continue to grow. 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 areas and the activities within them use resources and produce byproducts such as waste and pollution that drive many types of global change, such as resource depletion, land-use change, loss of biodiversity, and high levels of energy use and greenhouse gas emissions. Special Issue "Local Government Responses to Catalyse Sustainable Urban What are the 5 responses to urban sustainability challenges? Principle 4: Cities are highly interconnected. UCLA will unveil plans on Nov. 15 designed to turn Los Angeles into a global model for urban sustainability. 11: 6486 . 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. Dissolved oxygen, pH, turbidity, nitrates, and bioindicators. It will require recognition of the biophysical and thermodynamic aspects of sustainability. Fertilizers, pesticides, and insecticides. Part of the solution lies in how cities are planned, governed, and provide services to their citizens. As networks grow between extended urban regions and within cities, issues of severe economic, political, and class inequalities become central to urban sustainability. Much of the current information on urban areas is about stocks or snapshots of current conditions of a single place or location. Urbanization is a global phenomenon with strong sustainability implications across multiple scales. In a kickoff event at UCLA's Royce Hall (see event video), Chancellor Gene Block will describe the ambitious project . In an era that is characterized by global flows of commodities, capital, information, and people, the resources to support urban areas extend the impacts of urban activities along environmental, economic, and social dimensions at national and international levels, and become truly global; crossing these boundaries is a prerequisite for sustainable governance. It can be achieved by reducing, reusing, and recycling materials. Proper disposal, recycling, and waste management are critical for cities. Human well-being and health are the cornerstones of livable and thriving cities although bolstering these relationships with myopic goals that improve human prosperity while disregarding the health of natural urban and nonurban ecosystems will only serve to undermine both human and environmental. 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). Ultimately, the laws of thermodynamics limit the amount of useful recycling. 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. 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. Specific strategies can then be developed to achieve the goals and targets identified. Urban sustainability is the practice of making cities more environmentally friendly and sustainable. The major causes of suburban sprawl are housing costs,population growth,lack of urban planning, andconsumer preferences. Indeed, it is unrealisticand not necessarily desirableto require cities to be solely supported by resources produced within their administrative boundaries. For a renewable resourcesoil, water, forest, fishthe sustainable rate of use can be no greater than the rate of regeneration of its source. I. 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. With poor quality, the health and well-being of residents can be jeopardized, leading again to possible illness, harm, or death. Water resources in particular are at a greater risk of depletion due to increased droughts and floods. 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). These win-win efficiencies will often take advantage of economies of scale and adhere to basic ideas of robust urbanism, such as proximity and access (to minimize the time and costs of obtaining resources), density and form (to optimize the use of land, buildings, and infrastructure), and connectedness (to increase opportunities for efficient and diverse interactions). It is also important to limit the use of resources that are harmful to the environment. This is particularly relevant as places undergo different stages of urbanization and a consequent redrawing of borders and spheres of economic influence. Resources Cities need resources such as water, food and energy to be viable. 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. 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). Developing new signals of urban performance is a crucial step to help cities maintain Earths natural capital in the long term (Alberti, 1996). 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. First, greater and greater numbers of people are living in urban areasand are projected to do so for the foreseeable future. The article aims to identify the priority policy/practice areas and interventions to solve sustainability challenges in Polish municipalities, as well as . In order for urban places to be sustainable from economic, environmental, and equity perspectives, pathways to sustainability require a systemic approach around three considerations: scale, allocation, and distribution (Daly, 1992). (2015), and Rosado et al. Sustainable cities: research and practice challenges Once established, urban metabolism models supported by adequate tools and metrics enable a research stream to explore the optimization of resource productivity and the degree of circularity of resource streams that may be helpful in identifying critical processes for the sustainability of the urban system and opportunities for improvement. City leaders must move quickly to plan for growth and provide the basic services, infrastructure, and affordable housing their expanding populations need. An important example is provided by climate change issues, as highlighted by Wilbanks and Kates (1999): Although climate change mainly takes place on the regional to global scale, the causes, impacts, and policy responses (mitigation and adaptation) tend to be local. Principle 2: Human and natural systems are tightly intertwined and come together in cities. Urban Sustainability Indicators, Challenges and Opportunities 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. Identify your study strength and weaknesses. Name some illnesses that poor water quality can lead to. How can regional planning efforts respond tourban sustainability challenges? Jump up to the previous page or down to the next one. Urban governments are tasked with the responsibility of managing not only water resources but also sanitation, waste, food, and air quality. Share a link to this book page on your preferred social network or via email. 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. StudySmarter is commited to creating, free, high quality explainations, opening education to all. Sign up to highlight and take notes. However, many of these areas may be contaminated and polluted with former toxins and the costs of clean-up and redevelopment may be high. Copyright 2023 National Academy of Sciences. The spread and continued growth of urban areas presents a number of concerns for a sustainable future, particularly if cities cannot adequately address the rise of poverty, hunger, resource consumption, and biodiversity loss in their borders. Some of the major advantages of cities as identified by Rees (1996) include (1) lower costs per capita of providing piped treated water, sewer systems, waste collection, and most other forms of infrastructure and public amenities; (2) greater possibilities for, and a greater range of options for, material recycling, reuse, remanufacturing, and the specialized skills and enterprises needed to make these things happen; (3) high population density, which reduces the per capita demand for occupied land; (4) great potential through economies of scale, co-generation, and the use of waste process heat from industry or power plants, to reduce the per capita use of fossil fuel for space heating; and (5) great potential for reducing (mostly fossil) energy consumption by motor vehicles through walking. Name three countries with high air quality. Have all your study materials in one place. Environmental disasters are more likely to occur with greater intensity; buildings, streets, and facilities are more likely to be damaged or destroyed. Regional planning can also help create urban growth boundaries, a limit that determines how far an urban area will develop spatially. New Urban Sustainability Framework Guides Cities Towards a Greener Future Over the long term and at global scales, economic growth and development will be constrained by finite resources and the biophysical limits of the planet to provide the resources required for development, industrialization, and urbanization. Sign up for email notifications and we'll let you know about new publications in your areas of interest when they're released. 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. Complementary research showed that clean air regulations have reduced infant mortality and increased housing prices (Chay and Greenstone, 2005; EPA, 1999). The environmental effects of suburban sprawl include What are some urban sustainability practices that could prevent suburban sprawl? Click here to buy this book in print or download it as a free PDF, if available. For the APHG Exam, remember these six main challenges! How did the federal government influence suburban sprawl in the US? The majority of natural resources in the world are consumed in cities. 2 - River in the Amazon Rainforest; environmental challenges to water sustainability depend on location and water management. urban sustainability in the long run. 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 ]. In each parameter of sustainability, disruptions can only be withstood to a certain level without possible irreversible consequences. Cities are not islands. Very little information on the phases of urban processes exists, be it problem identification or decision making. Cities in developed countries may create more waste due to consuming and discarding a greater amount of. See the explanations on Suburbanization, Sprawl, and Decentralization to learn more! Fresh-water rivers and lakes which are replenished by glaciers will have an altered timing of replenishment; there may be more water in the spring and less in the summer. As climate change effects intensify extreme weather patterns, disturbances in water resources can occur. Lack of regulation and illegal dumping are causes for concern and can lead to a greater dispersion of pollutants without oversight. 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). Designing a successful strategy for urban sustainability requires developing a holistic perspective on the interactions among urban and global systems, and strong governance. 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). Reducing severe economic, political, class, and social inequalities is pivotal to achieving urban sustainability. 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. 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. The effort of promoting sustainable development strategies requires a greater level of interaction between different systems and their boundaries as the impacts of urban-based consumption and pollution affect global resource management and, for example, global climate change problems; therefore, pursuing sustainability calls for unprecedented system boundaries extensions, which are increasingly determined by actions at the urban level. View our suggested citation for this chapter. 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. Activities that provide co-benefits that are small in magnitude, despite being efficient and co-occurring, should be eschewed unless they come at relatively small costs to the system. All different types of waste must be properly managed in cities. The six main challenges to urban sustainability include: Other urban sustainability challenges include industrial pollution, waste management, and overpopulation. 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. Washington, DC: The National Academies Press. Thus, localities that develop an island or walled-city perspective, where sustainability is defined as only activities within the citys boundaries, are by definition not sustainable. 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 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. Furthermore, the governance of urban activities does not always lie solely with municipal or local authorities or with other levels of government. This is a challenge because it promotes deregulated unsustainable urban development, conversion of rural and farmland, and car dependency. 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. Urban Innovation 1: Sustainability and Technology Solutions - Udemy Currently, urban governance is largely focused on single issues such as water. 3 Principles of Urban Sustainability: A Roadmap for Decision Making, 5 A Path Forward: Findings and Recommendations, Appendix A: Committee on Pathways to Urban Sustainability: Challenges and Opportunities Biographical Information, Appendix B: Details for Urban Sustainability Indicators, Appendix C: Constraints on the Sustainability of Urban Areas. Poor neighborhoods have felt the brunt of dumping, toxic waste, lack of services, and limited housing choices (Collin and Collin, 1997; Commission for Racial Justice, 1987). Key variables to describe urban and environmental systems and their interrelationships; Measurable objectives and criteria that enable the assessment of these interrelationships; and. Fig. These strategies should not be developed in isolation, but rather in collaboration with, or ideally, developed by, the practitioners responsible for achieving the goals and targets. Turbidity is a measure of how ___ the water is. Sustainability | Free Full-Text | Smart and Resilient Urban Futures for Although cities concentrate people and resources, and this concentration can contribute to their sustainability, it is also clear that cities themselves are not sustainable without the support of ecosystem services, including products from ecosystems such as raw materials and food, from nonurban areas. One is that the ecological footprint is dominated by energy as over 50 percent of the footprint of most high- and middle-income nations is due to the amount of land necessary to sequester greenhouse gases (GHGs). In this step it is critical to engage community members and other stakeholders in identifying local constraints and opportunities that promote or deter sustainable solutions at different urban development stages. Without regional planning, rural and suburban towns will grow but will have a massive amount of commuters demanding greater highway access. In recent years, city-level sustainability indicators have become more popular in the literature (e.g., Mori and Christodoulou, 2012). Energy conservation schemes are especially important to mitigate wasteful energy use. Ultimately, given its U.S. focus and limited scope, this report does not fully address the notion of global flows. Some promising models exist, such as MITs Urban Metabolism framework, that warrant further development (Ferro and Fernndez, 2013). In most political systems, national governments have the primary role in developing guidelines and supporting innovation allied to regional or global conventions or guidelines where international agreement is reached on setting such limits. Sustainable Cities: Urban Planning Challenges and Policy Read "Pathways to Urban Sustainability: Challenges and Opportunities 3, Industrial Pollution in Russia (https://commons.wikimedia.org/wiki/File:Industry_in_Russia.jpg), by Alt-n-Anela (https://www.flickr.com/people/47539533@N05), licensed by CC-BY-2.0 (https://creativecommons.org/licenses/by/2.0/deed.en), Fig. This can include waste made by offices, schools, and shops. In other words, the challenges are also the reasons for cities to invest in sustainable urban development. Poor resource management can not only affect residents in cities but also people living in other parts of the world. Such a framework of indicators constitutes a practical tool for policy making, as it provides actionable information that facilitates the understanding and the public perception of complex interactions between drivers, their actions and impacts, and the responses that may improve the urban sustainability, considering a global perspective.
