Valuing the Benefits of Nature-Based Solutions : A Manual for Integrated Urban Flood Management in China

Floods are the most frequent of all-natural hazards and responsible for causing more damages than any other disasters. Globally, floods are estimated to have affected more than 2 billion people between 1998 and 2018, accounting for 45 percent of al...

Globally, floods are estimated to have affected more than 2 billion people between 1998 and 2018, accounting for 45 percent of all people affected by disasters during that period with an estimated 142,088 fatalities.
