Effective Ecosystem-based Adaptation" reduces a range of climate change risks to people, biodiversity and ecosystem services with multiple co-benefits . Ecosystem-based Adaptation is vulnerable to climate change impacts, with effectiveness declining with increasing global warming . Urban greening using trees and other vegetation can provide local cooling . Natural river systems, wetlands and upstream forest ecosystems reduce flood risk by storing water and slowing water flow, in most circumstances . Coastal wetlands protect against coastal erosion and flooding associated with storms and sea level rise where sufficient space and adequate habitats are available until rates of sea level rise exceeds natural adaptive capacity to build sediment .
