what are five responses to urban sustainability challenges?

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). suburban sprawl, sanitation, air and water quality, climate change, energy use, and the ecological footprint of cities. 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 because as cities grow, more resources are needed for maintaining economic conditions in a city. 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 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. The other is associated to the impact of technology intensity that is assumed for characterizing productivity in terms of the global hectare. Assessing a citys environmental impacts at varying scales is extremely difficult. 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). Proper land-use designation and infrastructure planning can remedy the effects of urban growth. Lack of regulation and illegal dumping are causes for concern and can lead to a greater dispersion of pollutants without oversight. Very little information on the phases of urban processes exists, be it problem identification or decision making. At its core, the concept of sustainable development is about reconciling development and environment (McGranahan and Satterthwaite, 2003). Healthy human and natural ecosystems require that a multidimensional set of a communitys interests be expressed and actions are intentional to mediate those interests (see also Box 3-2). This is a challenge because it promotes deregulated unsustainable urban development, conversion of rural and farmland, and car dependency. Dissolved oxygen, pH, turbidity, nitrates, and bioindicators. 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. 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. 11: 6486 . A strip mall is built along a major roadway. Fig. There is a general ignorance about. 5. Key variables to describe urban and environmental systems and their interrelationships; Measurable objectives and criteria that enable the assessment of these interrelationships; and. (2012) argued that the laws of thermodynamics and biophysical constraints place limitations on what is possible for all systems, including human systems such as cities. More about Challenges to Urban Sustainability, Fig. The implementation of long-term institutional governance measures will further support urban sustainability strategies and initiatives. 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.
