All cities are fragile. Some cities are more fragile than others. Approximately 240 (11%) exhibit “high” fragility, 1,490 (71%) register “medium” fragility and 350 (13%) report ”low” fragility.
There are over 2,100 cities with populations of 250,000 or more. The world’s cities cover just 2% of the earth’s surface, but account for 55% of its total population.
The scale of urbanization defies traditional models of urban geography. Today’s urban landscape includes super cities (over 40m), hyper cities (over 30m) and megacities (over 10m). Old planning models no longer apply.
Urban fragility is concentrated in Middle, Eastern, Western and Southern Africa, followed by Western, Southern and South-Eastern Asia.
The most fragile cities in the world are currently located in Iraq, Syria, Libya, Somalia, South Sudan, Sudan, and Yemen. There are pockets of fragility in Afghanistan, DRC, Madagascar, Mali, Nigeria, Pakistan and the Philippines.
Cities reporting low fragility scores are located in Australia, North America, Western Europe and parts of South, Southeast, and East Asia. Many of these cities show resilience to shocks and hazards.
