Rapid urbanization in the Global South puts strain on infrastructure systems and worsens environmental degradation. Poor infrastructure investment often results in informal settlements and slums that increase flood vulnerability while undermining basic services provision [52-53].
Governance problems such as ineffective management of public institutions and policy contradictions obstruct sustainable infrastructure development. To counteract this problem, reforms that clarify institutional responsibilities while improving transparency and accountability may provide relief.
Green infrastructure
Green infrastructure refers to a range of practices that help cities integrate nature into their urban landscapes for environmental, economic and social gains. It encompasses everything from green roofs and bio-swales to street planting and urban forests as well as restored wetlands and river corridors.
Local governments can use various policy tools to facilitate green infrastructure implementation. These may include regulations and incentives targeted towards private property owners as well as planning and management tools that enable widespread deployment of green infrastructure projects throughout their cities.
Effective local strategies incorporate green infrastructure into broader planning processes that govern municipal operations, including street design standards and capital planning processes that guide road construction; facilities management processes that oversee construction outside the streetscape such as parks or recreation areas; and facilities management plans used by facilities managers. Such comprehensive plans can maximize pilot programs while simultaneously helping local governments identify opportunities to invest in green infrastructure that will accomplish multiple goals simultaneously.
Resilience and adaptation
Sustainable urban infrastructure should incorporate resilience and adaptation as part of its strategy for balancing economic development with environmental protection, especially in cities with high populations and energy use. Failure to take into account their ecological footprint could do more damage than good; they should adopt a new burg model which incorporates compact living, renewable energy sources, and public transit as soon as possible.
Yokohama, Japan is internationally renowned as an innovative leader in integrated infrastructure planning and sustainability. Through our Smart Cities and Urban Transformation Training & Study Tour participants gain practical perspectives on integrated city management, project prioritization, governance models and sustainability principles in this high-performing and pioneering urban environment.
Sustainable urban infrastructure development is a key part of transitioning toward a low-carbon economy. It can reduce emissions by cutting use of fossil fuels, while supporting green economies in emerging and developing nations. Furthermore, sustainable infrastructure may help alleviate poverty in these nations by providing access to essential services and driving green job growth.
Economic development
Sustainable urban infrastructure planning and design necessitates taking an integrated approach that considers environmental, economic, and social impacts – taking this comprehensive approach can result in creating an urban environment which is more resilient, productive, and dependent upon fossil fuels than before.
Hedonic pricing methodology makes it possible to measure the indirect benefits of urban infrastructure investments, including property values, induced spending, job creation, poverty alleviation and other catalytic impacts. For instance, it can help estimate how many more people would spend money by living near an infrastructure project such as a greenway or transit station.
An analysis of past and forecast infrastructure inequality shows that both WR and BR inequality tend to increase with economic development and urbanization; however, our findings show that regional economic disparities can significantly alter these trends; also some countries will experience decoupled changes between both variables.
Social equity
Social equity is an integral component of sustainable urban infrastructure strategies. This principle seeks to provide access to opportunities that enable individuals and groups to reach their full potential; such as education, healthcare, housing and transportation access as well as environmental, climate and economic justice issues.
Public administrators should go beyond improving planning processes to foster participation from diverse stakeholders; they should seek ways to address local inequities through measures such as analyzing data to detect disparities and taking appropriate steps to mitigate them.
Recently passed US legislation will fund projects that foster housing rehabilitation and weatherization with an equity lens in mind, with an aim of helping those communities disproportionately impacted by climate change, disasters or pollution to find ways of overcoming their difficulties.
