If you follow the “Resilient City” theme on the internet you often come across the United Nations’ Sustainable Development Goal 11 which is to “Make cities and human settlements inclusive, safe, resilient and sustainable”.
The text states that more than half of the world population live in cities and that the fraction is expected to rise. However, this urban population growth is often outstripping the rate of development of the cities resulting in slum conditions, often overflowing the formal administrative boundaries of the cities.
As the size of cities increases the per-capita carbon dioxide emissions increase, the difficultly of removing solid wastes increases while air quality tends to reduce.
Against Goal 11 the UN has a number of targets that aim to improve the conditions for the urban poor with adequate housing and public transport, inclusion, reduced impact of natural disasters – particularly on the urban poor, improved city environments with public open spaces and improved urban planning.
These goals are all very laudable and, with a completion date of 2030 placed on many of them, very challenging.
This is important work. Vital for the future of humanity. But less relevant to the resilient cities theme in the developed world and temperate climate.
