Thailand’s proposed THB165 billion (US$4.91 billion) flood diversion project presents an opportunity to rethink flood management – combining engineering with natural floodplains, wetlands and river restoration to strengthen long-term resilience.
Replenishing depleted groundwater could slow or even reverse land subsidence in coastal cities – but fault lines can determine where and how quickly the ground rises.
Cities worldwide are sinking as groundwater extraction and rapid development drive land subsidence – but stark differences within cities are exposing some communities to far greater flood risks.
