Rapid urbanisation also means that the game for the quality of life and the health of the citizens will be won or lost in the cities. Barcelona-based architect Eloi Juvillà Ballester analyses the potential of urban green spaces as decisive component in this game.

In Namibia, the major share of urban growth is informal, with an estimated 30-40 per cent of the population living in informal settlements, with trends projecting shacks to become the predominant form of housing by 2025. Being especially vulnerable to climate change, these forms of settlements require special attention in the development of climate resilience strategies.
High density and poor building materials make informal settlements extremely prone to fire hazards. The Nairobi-based enterprise Kwangu Kwako has developed a housing model that, while being truly affordable, increases fire resilience and thus positively affects many aspects of residents' lives.
As densely populated urban areas like Homs, Raqqa, and Idlib in Syria continue to be the site of years-long armed conflicts, architect Ammar Azzouz argues that cities must not wait for post-conflict reconstruction plans.

Urban areas around the world face the challenge of delivering affordable housing to ever growing populations.

Pietermaritzburg, South Africa, commits to implementation of the SDGs. To this end, the city focusses on sustainable construction, always ensuring to align the SDGs with national policies.
Cape Town is committed to providing clean, affordable and accessible energy to all its residents. Increasing the use of renewable energy, implementing innovative financing options, and challenging national energy legislation are some of the ways the city hopes to shift away from a history of inequality, writes Mary Haw.
Ecosystem loss and degradation contributes to water insecurity worldwide – natural infrastructure strategies that protect and restore natural systems aim to halt and reverse this trend. Suzanne Ozment and Rafael Feltran-Barbieri discuss how water utilities can profit from restoring ecosystems.
How can digitalisation of urban services increase sustainable urbanisation? What different approaches and innovations already exist and have proven successful? Kala Vairavamoorthy, director of the International Water Association addresses these questions.
