Global ecosystem services revalued at US$125-145 trillion per year

30 May 2014

Following on from the ground-breaking Costanza et al. work in 1997, which valued the planet's ecosystem services (trees filtering air and water, insects pollinating crops, earthworms putting nutrients back into the soil, plants storing carbon, mental health benefits of green spaces, etc.) at US$33 trillion per year, and after much criticism, this work has now been revised and global ecosystem services have been revalued at between US$125 trillion and US$145 trillion per year.

The research estimates that the loss of ecosystem services from 1997 to 2011 is in the order of US$20 trillion per year.

This work continues to emphasise the importance of ecological and environmental expertise and skills needed to safeguard, restore and enhance our natural environment and the services that they provide. These professionals will be the cornerstone of sustainably managing our natural resources into the future.
