A major project identifying, mapping and valuing natural capital and ecosystem services across the Nene Valley. The monetary value of three ecosystem services was assessed and valued at £118.7m each year. Eleven other ecosystem services were mapped, and presented in the form of supply and demand maps. The aims of this project were to: highlight the key benefits provided by the natural environment; increase understanding of the interdependencies between the environment, economy and people; and to aid planners and decision makers.
