Sustainable urban infrastructure fosters a new economy rooted in climate and sustainability actions, including environmental protocols, multidisciplinary practices and the consideration of ecological data when selecting projects.
These strategies include mixed-use designs that combine housing, offices and businesses into single buildings to reduce commute times and greening the city with trees and other forms of vegetation to improve air quality and decrease heat-related efficiency losses.
Garden City
Garden cities were developed as an utopian urban planning initiative which sought to foster better communities and lives for its inhabitants. People can connect to one another as well as nature through these charming environments.
Ebenezer Howard first put forth this idea in his book “Tomorrow”. His vision included compact, self-sustaining towns surrounded by greenbelts to protect wildlife habitats and farmland from being developed further.
Garden cities have spread across the world, influencing colonial and postcolonial capitals such as New Delhi (designed in 1931), Canberra (Australian capital established in 1913), Quezon City (capital of Philippines 1948-1976) as well as Canadian suburbs like Don Mills-Windsor and Montreal’s King’sway neighbourhood which follow garden city designs.
Resilient City
Urban resilience refers to a city’s ability to cope and adapt in response to various environmental threats and economic downturns, including natural disasters and economic downturns. It requires robust infrastructure, sustainable practices, community engagement and social equity among other components.
Communities and citizens play an integral part in making cities resilient. That is why 100 Resilient Cities’ strategies focus heavily on inclusion and collaboration through activities like workshops, panel discussions and networking events that enable people to share ideas and best practices.
Communities benefit from these efforts by developing the capability to respond and recover from future challenges, including natural disasters and safeguard development gains for future generations. This effort is especially crucial as more people move into cities.
Green Infrastructure
Green infrastructure – which integrates natural elements into urban development – is becoming an essential element in sustainable city planning initiatives. It serves to address environmental challenges while supporting ecosystem services like water management, biodiversity enhancement, air purification and urban cooling.
At home, this can include rain gardens and permeable pavements that reduce stormwater runoff and sewage overflow. At the city level, this may include parks, tree plantings, community gardens, bio-swales, green roofs and walls as well as rehabilitated wetlands, floodplains and river systems.
Communities need to be informed and engaged with green infrastructure projects for them to reap all their benefits, which can be accomplished via education campaigns, community involvement programs, collaborative decision-making processes and creating opportunities to support local businesses involved in green infrastructure initiatives.
Energy-Efficient Buildings
Energy efficiency is a cornerstone of sustainable urban infrastructure. Energy-saving practices reduce the embodied energy of buildings by cutting the amount of electricity and fuel required to operate them, thus decreasing their overall impact.
Energy efficiency initiatives can also reduce peak demand on the electric grid by decreasing how much electricity is used during periods of peak energy consumption. Furthermore, they can save a significant amount of water resources that may otherwise be limited in urban settings.
Building efficiency is an integral component of climate change mitigation. WRI assists local governments in creating ambitious, inclusive and resilient building roadmaps to accelerate action. This work is carried out through our WRI Ross Center for Sustainable Cities Built Environment team – for more details contact Tini Tran.
Shared Living
Urbanisation necessitates more than simply altering buildings and transport systems – it necessitates changes to lifestyles and living arrangements to lessen our ecological impact and achieve sustainability.
Social infrastructure – including cultural and community spaces and public places – creates opportunities for socioecological interactions and activities to occur, strengthening social cohesion while hastening sustainable transitions.
Challenges associated with green and social infrastructure include making sure it is inclusive, accessible to people of all socioeconomic groups and locations, meeting their needs in an integrated manner, as well as designed to maximise biodiversity and promote resilience – for example considering how nature-based solutions (NBSs) may contribute to climate mitigation, adaptation and resilience towards achieving climate neutral cities while meeting social functions.
