by Tracy Stanton; Katherine Hamilton

Jan 1, 2010
A global research effort conducted by Ecosystem Marketplace identified a total of approximately 288 payments for watershed services (PWS) and water quality trading (WQT) programs in varying stages of activity over the past 30 years. In 2008, the baseline year, about 127 programs were actively receiving payments or transacting credits. The total transaction value from all programs actively engaged in 2008 is estimated at US$9.3 billion. Over the entire time span of recorded activity, total transaction value is estimated at slightly more than US$50 billion, impacting some 3.24 billion hectares.
