what are five responses to urban sustainability challenges?

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). 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. How can suburban sprawl be a challenge to urban sustainability? Understanding indicators and making use of them to improve urban sustainability could benefit from the adoption of a DPSIR framework, as discussed by Ferro and Fernndez (2013). What are some anthropogenic causes of air pollution? Reducing severe economic, political, class, and social inequalities is pivotal to achieving urban sustainability. To avoid negative consequences, it is important to identify the threshold that is available and then determine the actual threshold values. Fill in the blanks. As described in Chapter 2, many indicators and metrics have been developed to measure sustainability, each of which has its own weaknesses and strengths as well as availability of data and ease of calculation. All different types of waste must be properly managed in cities. There are many policy options that can affect urban activities such that they become active and positive forces in sustainably managing the planets resources. 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. A practitioner could complement the adopted standard(s) with additional indicators unique to the citys context as necessary. It nevertheless serves as an indicator for advancing thinking along those lines. True or false? Poor resource management can not only affect residents in cities but also people living in other parts of the world. Meeting development goals has long been among the main responsibilities of urban leaders. The majority of natural resources in the world are consumed in cities. Concentrated energy use leads to greater air pollution with significant. 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. 3 Clark, C. M. 2015. 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. Commercial waste is generated by businesses, usually also in the form of an overabundance of packaged goods. October 15, 2015. In other words, the challenges are also the reasons for cities to invest in sustainable urban development. Fig. This course is an introduction to various innovators and initiatives at the bleeding edge of urban sustainability and connected technology. 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. 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. 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. UA is thus integral to the prospect of Urban Sustainability as SDG 11 ("Make cities and human settlements inclusive, safe, resilient and sustainable") of the U.N.'s 2030 Agenda for Sustainable Development. Identify your study strength and weaknesses. Regional planning can also help create urban growth boundaries, a limit that determines how far an urban area will develop spatially. Nongovernmental organizations and private actors such as individuals and the private sector play important roles in shaping urban activities and public perception. (2015), and Rosado et al. Jump up to the previous page or down to the next one. Community engagement will help inform a multiscale vision and strategy for improving human well-being through an environmental, economic, and social equity lens. 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. 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. What are two environmental challenges to urban sustainability? As climate change effects intensify extreme weather patterns, disturbances in water resources can occur. Cities have experienced an unprecedented rate of growth in the last decade. See the explanations on Suburbanization, Sprawl, and Decentralization to learn more! Create the most beautiful study materials using our templates. Efforts to reduce severe urban disparities in public health, economic prosperity, and citizen engagement allow cities to improve their full potential and become more appealing and inclusive places to live and work (UN, 2016b). Learn about and revise the challenges that some British cities face, including regeneration and urban sustainability, with GCSE Bitesize Geography (AQA). More than half the worlds population lives in urban areas, with the U.S. percentage at 80 percent. The task is, however, not simple. Let's take a look at how the challenges of sustainable urban development may not be challenges at allit all depends on perspective! How can regional planning efforts respond tourban sustainability challenges? The challenges to urban sustainability are also what motivate cities to be more 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. For instance, domestic waste is household trash, usually generate from packaged goods. Proper disposal, recycling, and waste management are critical for cities. 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. Intensive urban growth can lead to greater poverty, with local governments unable to provide services for all people. 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 Indicates air quality to levels to members of the public. Some of the challenges that cities and . 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. Examples of Urban Sustainability Challenges 2. 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. In short, urban sustainability will require a reconceptualization of the boundaries of responsibility for urban residents, urban leadership, and urban activities. These opportunities can be loosely placed in three categories: first, filling quantitative data gaps; second, mapping qualitative factors and processes; and third, identifying and scaling successful financing models to ensure rapid adoption. Ultimately, the laws of thermodynamics limit the amount of useful recycling. (2009), NRC (2004), Pina et al. These policies can assist with a range of sustainability policies, from providing food for cities to maintaining air quality and providing flood control. 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. Poor resource management can not only affect residents in cities but also people living in other parts of the world. Power plants, chemical facilities, and manufacturing companies emit a lot of pollutants into the atmosphere. One challenge in the case of cities, however, is that many of these shared resources do not have definable boundaries such as land. 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. Statement at NAS Exploratory Meeting, Washington, DC. Together, cities can play important roles in the stewardship of the planet (Seitzinger et al., 2012). Climate change, pollution, inadequate housing, and unsustainable production and consumption are threatening environmental justice and health equity across generations, socioeconomic strata, and urban settings. By 2045, the world's urban population will increase by 1.5 times to 6 billion. Each city's challenges are unique; however, many have implemented one or more of the following in their efforts to develop their own integrated solutions: 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. Getting an accurate picture of the environmental impacts of all human activity, including that of people working in the private sector, is almost impossible. . 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. 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). In recent years, city-level sustainability indicators have become more popular in the literature (e.g., Mori and Christodoulou, 2012). What are the 5 responses to urban sustainability challenges? City leaders must move quickly to plan for growth and provide the basic services, infrastructure, and affordable housing their expanding populations need. 2 - River in the Amazon Rainforest; environmental challenges to water sustainability depend on location and water management. 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). 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). The major causes of suburban sprawl are housing costs,population growth,lack of urban planning, andconsumer preferences. Overpopulation occurs when people exceed the resources provided by a location. Chapter 4 explores the city profiles and the lessons they provide, and Chapter 5 provides a vision for improved responses to urban sustainability. 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. True or false? Transportation, industrial facilities, fossil fuels, and agriculture. 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. Since materials and energy come from long distances around the world to support urban areas, it is critical for cities to recognize how activities and consumption within their boundaries affect places and people outside their boundaries. Making cities more resilient against these environmental threats is one of the biggest challenges faced by city authorities and requires urgent attention. At its core, the concept of sustainable development is about reconciling development and environment (McGranahan and Satterthwaite, 2003). 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). This can assist governments in preserving natural areas or agricultural fields. 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). Finally, the greater challenge of overpopulation from urban growth must be addressed and responded to through sustainable urban development. A holistic view, focused on understanding system structure and behavior, will require building and managing transdisciplinary tools and metrics. 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. 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. However, many of these areas may be contaminated and polluted with former toxins and the costs of clean-up and redevelopment may be high. AQI ranged 51-100 means the air quality is considered good. 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. 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. 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. 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 ]. 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). So Paulo Statement on Urban Sustainability: A Call to Integrate Our Responses to Climate Change, Biodiversity Loss, and Social Inequality . Two trends come together in the world's cities to make urban sustainability a critical issue today. 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. ), as discussed in Chapter 2. Further, unpredictable timing and quantity of precipitation can both dry up growing crops or lead to flash floods. The challenge is to develop a new understanding of how urban systems work and how they interact with environmental systems on both the local and global scale. 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. A concern for sustainable development retains these conventional concerns and adds two more. Some promising models exist, such as MITs Urban Metabolism framework, that warrant further development (Ferro and Fernndez, 2013). UCLA will unveil plans on Nov. 15 designed to turn Los Angeles into a global model for urban sustainability. 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. A suburban development is built across from a dense, urban neighborhood. 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. How many goods are imported into and exported from a city is not known in practically any U.S. city. The future of urban sustainability will therefore focus on win-win opportunities that improve both human and natural ecosystem health in cities.
