Building codes and land-use regulation have proven to be the most eective tools to promote health and saety in cities and reduce disaster risk. Low- and middle-income countries have suffered over 90% of all disaster-related fatalities since 1990. Climate change threatens to make this trend even worse, and may push 100 million more into poverty. Major development partners like the World Bank and the Global Facility for Disaster Reduction and Recovery (GFDRR), along with governments, civil society groups, and the private sector, are coming together to better address these challenges. The new BUILDING REGULATION FOR RESILIENCE program, an unprecedented global partnership, will help improve implementation and compliance o eective building regulation in vulnerable countries. With applied science, sound engineering, and the right institutions, we can build well-designed cities and safer buildings that help protect lives and ensure that development gains won’t crumble or be washed away in disasters.
