Sustainable urban infrastructure refers to equipment and systems designed, built, and maintained with an emphasis on ecological, financial, social, environmental (including climate resilience) sustainability.
Meristem Design provides solutions that harness nature to regenerate spaces such as cement and tarmac spaces into green, absorbent multifunctional zones – including living walls – using their powerful regeneration strategies.
Water
Sustainable urban water infrastructure comprises systems that supply drinking and irrigation water, protect local environments from flooding and contamination, collect used water for treatment and recycle it as necessary, as well as policies and planning processes which facilitate transition from traditional, centralized infrastructures towards hybrid integrated systems that offer more resilience against climate change.
These hybrid systems incorporate “green infrastructure”, such as urban forests, parks and greenways that utilize natural processes to meet multiple objectives simultaneously: pollution control, groundwater recharge, urban heat-island reduction, biodiversity enhancement and aesthetic beauty enhancement – in other words: multiple purposes at once! They may even reduce the need for manmade flood infrastructure like levees.
Utilizing natural resources, like green space and urban streams, to deliver infrastructure services can reduce costs associated with climate impacts while creating numerous advantages for citizens – making nature-based infrastructure (NBI) an economical solution for cities. Strategic cross-sectoral spatial planning should place NBI development as one of its goals.
Energy
Cities provide home for most of the global population and contribute to 70% of greenhouse gas emissions worldwide. A sustainable urban infrastructure strives to balance the needs of both residents and the environment with reliable renewable energy sources that offer solutions.
Energy resources encompass electricity generation, transmission and distribution systems as well as telecommunication networks (cell towers and broadband internet connectivity). Urban green infrastructure also plays a part in cutting costs by helping regulate temperature; thus lowering heat-related losses in power systems.
Green spaces are integral to a city’s future success. From pollution reduction and public health benefits, to climate regulation and tourism/property development opportunities, green spaces provide multiple benefits simultaneously for their community members – from pollution control, to stabilizing climate conditions, tourism/property development benefits and tourism/property value add. Nature-based infrastructure (NBI) delivers cost-effective climate-resilient infrastructure services while offering co-benefits such as urban forests/wetlands/grasslands preventing flooding while filtering water/regulating temperature regulation benefits – among many more benefits for citizens. NBI infrastructure delivers cost effective climate-resilient infrastructure services which generate many co-benefits from infrastructure services while offering co-benefits co-benefits to citizens. Urban forests/wetlands/grasslands provide water filtration/temperature regulation co-benefits over their counterparts in terms of co-benefits generated.
Transportation
Rapid urban expansion is straining infrastructure resources across the world, including energy supplies, transportation networks and waste disposal systems. Upgrading existing urban infrastructure to support population growth while improving quality of life and decreasing environmental impacts is vital.
Provide sustainable transport options to reduce traffic congestion and emissions is of vital importance. Investing in electric buses, rail systems and other forms of public transit powered by renewable energy will both benefit the environment while saving on fuel costs. Furthermore, creating walkable communities may encourage less car use thus aiding air quality management.
Massive transit projects can have an enormous ecological footprint during construction and demand a great deal of resources to run long term. To create sustainable transport infrastructure requires careful consideration of its overall impacts and an openness to exploring alternative forms of travel. Educating people on sustainable travelling strategies may prove fruitful: the result may include reduced emissions, increased access to jobs and services and even an uptick in local economies.
Waste Management
Imagine living in dense urban centers free of air pollution and abundant with green ecosystems, where more people walk or ride bicycles than use cars as transport. That vision could become reality sooner than you think, though it requires global investment in sustainable infrastructure projects to get there.
An innovative financing mechanism known as social impact bonds may provide one way to do just that. By pooling private investments together to fund projects which produce tangible environmental, economic and community benefits.
Education also plays a crucial role. Teaching students about the various aspects of sustainability and their interconnection is crucial, whether that means through curriculum-based learning in schools and colleges, workshops or special seminars.
