How can sustainable urban development be promoted?

The prestigious London School of Economics estimates that by 2050 almost 70% of the world's population will live in cities. Until then we have many challenges to overcome to make cities more sustainable, inclusive and habitable, a fact that is recognised by the United Nations' (UN) New Urban Agenda.

Cities occupy only 3% of the earth's surface but more than 4 billion people live in them, according to data from the United Nations (UN) and the World Bank. This figure is increasing rapidly, especially in Africa and Asia, making it ever more difficult for urban centres to offer prosperity to its inhabitants, who suffer problems including pollution, inequality, restricted mobility, poor access to housing or a lack of infrastructure and services.


The UN approved the New Urban Agenda (NUA) at the Habitat 3 summit on housing and urban development held in Quito (Ecuador) in 2016 to help promote a new global model for sustainable urban planning. The document advises countries on how to face the challenges of urbanisation and invites them to direct their efforts towards sustainable urban development, as the UN itself reflects in its goals for 2030 (SDG 11).

The New Urban Agenda — the successor to the Habitat Agenda and the 1996 Istanbul Declaration — establishes how cities should be transformed to be habitable, inclusive, healthy, sustainable, safe, orderly, compact and resilient to natural phenomena. At the same time, it urges changes to the way they are planned, developed, governed and administered by acting through design, legislation, local economic policies and state urban planning policies.

The environment occupies a key place in the New Urban Agenda and new sustainable urbanism. Cities need to invest in green spaces, renewable energy, bioarchitecture and policies to promote recycling and responsible consumption in order to reduce pollution and make them healthier and more liveable places.

Environmental urbanism is driving the energy transition towards a less carbon-dependent model that more effectively combats climate change by reducing CO2 emissions. This conception of cities promotes biodiversity, efficient water use, soil and aquifer protection, the conservation of flora and fauna, public transport use and sustainable mobility, among other initiatives. In this way the New Urban Agenda is joining other concrete measures such as, for example, the regulation of building height, the preservation of open areas and the allocation of between 30 and 50% of the land to public spaces.

At the end of 2018, the Davos Forum revealed that, despite the progress made on the New Urban Agenda in the world, there are notable differences between countries and regions. The success of this global initiative requires the effort and cooperation of all the administrations involved as well as social awareness, financial resources, capacity development, innovation and commitment.

The World Economic Forum pointed out the main challenges facing the new sustainable town planning roadmap:

  • The New Urban Agenda lacks predefined indicators to measure its progress and leaves the choice and monitoring of results to local governments.
  • It takes time, training, specialisation and concerted effort to monitor and correctly evaluate the progress attributable to the agenda.
  • Favourable institutional frameworks are needed with adequate regulation, coordination mechanisms at all levels and a clear, accountable government structure.
  • Greater participation by local governments is appropriate, assuming more weight, control and power when making decisions.
  • The transformation of cities requires greater cooperation and dialogue between public authorities and the private sector, educational bodies and civil society.
