About 1.4 million people move to cities every week around the world, UN Secretary-General Antonio Guterres has said on the 'World Cities Day', warning that such a large rate of migration can contribute to increased risks from natural and human made disasters.
In his message for the 'World Cities Day', celebrated annually on October 31, Guterres stressed that "hazards do not need to become disasters".
"Every week, 1.4 million people move to cities. Such rapid urbanisation can strain local capacities, contributing to increased risk from natural and human made disasters. But hazards do not need to become disasters. The answer is to build resilience -- to storms, floods, earthquakes, fires, pandemics and economic crises," the UN chief said Tuesday.
Guterres explained that cities around the world are doing just that, forging new ways to increase resilience and sustainability.
Bangkok has built vast underground water storage facilities to cope with increased flood risk and save water for drier periods, he said.
The local government in Quito has reclaimed or protected more than 200,000 hectares of land to boost flood protection, reduce erosion and safeguard the city's freshwater supply and biodiversity, he said.
