What strategies are cities using to improve infrastructure?

Cities are employing strategies such as smart technology, green infrastructure, and public-private partnerships to improve infrastructure.

One of the most popular strategies is the use of smart technology. This involves the integration of information and communication technologies (ICT) into urban infrastructure to improve efficiency, sustainability, and the quality of life for residents. For example, cities are using sensors and data analytics to optimise traffic flow, reduce energy consumption, and improve waste management. In Barcelona, smart water meters have been installed to monitor and reduce water usage, while in Singapore, a network of sensors and cameras helps to manage traffic congestion.

Another strategy is the development of green infrastructure. This refers to the creation or enhancement of natural features within urban areas, such as parks, green roofs, and rain gardens, to provide ecosystem services and improve environmental quality. Green infrastructure can help to mitigate the impacts of climate change, improve air and water quality, and enhance urban biodiversity. For instance, in London, the Greater London Authority has developed a Green Infrastructure Task Force to promote the integration of green infrastructure into new developments.

Public-private partnerships (PPPs) are also being used to improve urban infrastructure. PPPs involve collaboration between the public sector and private companies to finance, build, and operate infrastructure projects. This approach can help to overcome funding constraints and leverage the expertise and efficiency of the private sector. For example, in Sydney, the New South Wales government has partnered with private companies to deliver the Sydney Metro project, which is Australia's largest public transport infrastructure project.

Furthermore, cities are adopting comprehensive urban planning approaches to improve infrastructure. This involves the strategic planning of land use, transportation, and other infrastructure to promote sustainable urban development. Comprehensive urban planning can help to ensure that infrastructure development is coordinated and aligned with broader urban development goals. For instance, in Copenhagen, the city's Finger Plan guides the development of infrastructure along five 'fingers', with green spaces in between, to promote balanced and sustainable urban growth.

Lastly, cities are also focusing on the maintenance and upgrading of existing infrastructure. This includes the repair and refurbishment of roads, bridges, and other infrastructure to ensure their continued functionality and safety. For example, in New York City, the Department of Transportation conducts regular inspections and maintenance of the city's bridges to ensure their structural integrity.
