Disaster risk is rising rapidly. The poorest and most vulnerable people are hit hardest. Many hazards are becoming more frequent and less predictable as a result of climate change. At the same time, environmental degradation erodes nature’s ability to regulate them, and to provide food and water. The result is that more people are caught in a vicious circle of poverty, risk and vulnerability, which drives mounting economic losses, and imposes ever greater costs of relief and rehabilitation on governments and agencies.
