Presently, the average annual loss from natural disasters in cities is estimated by the UN at over $250 billion. If cities fail to build their resilience to disasters, shocks, and ongoing stresses, this figure will rise to $314 billion by 2030, and 77 million more city dwellers will fall into poverty, according to a new World Bank/GFDRR report presented at COP22.
The good news is that we have a window of opportunity to make cities and the urban poor more resilient. Over 60% of the land projected to become urban by 2030 is yet to be developed. Additionally, cities will need to build nearly one billion new housing units by 2060 to house a growing urban population. Building climate-smart, disaster-resilient cities and housing is thus an immediate priority, especially in the developing world.
To seize that opportunity, countries will need significant financing for infrastructure—over $4 trillion annually—and making this infrastructure low carbon and climate resilient will cost an additional $0.4 to $1.1 trillion, according to a CCFLA report.
Mobilizing private capital is the best bet for helping to close this financing gap.
