A new TEEB -The Economics of Ecosystems and Biodiversity- initiative for Water and Wetlands will be launched at the UN's Summit on Sustainable Development on 15 June in Rio, Brazil. The new TEEB for Water and Wetlands aims to utilise the TEEB approach to generate a better understanding of the value of ecosystem services provided by water and wetlands, such as freshwater supply, food, building materials, risk reduction and flood control, groundwater recharge, biodiversity, climate change adaptation and more.
