Can short-term payments for ecosystem services deliver long-term tree cover change?

Can short-term payments for ecosystem services deliver long-term tree cover change?

Background

While payment for ecosystem services (PES) has been lauded has been an effective strategy, particularly to increase tree cover in agricultural areas. Yet, there has been limited evaluation of long-term success, such as that after the payment period.

Goals & Methods

To determine the the long-term effectiveness of PES, the author compares tree cover before and after 13 years of a PES project that promoted silvopastoral systems in Colombia, which was quantified via satellite images.

Conclusions & Takeaways

The author found treeless pastures decreased while tree cover in silvopastoral systems increased, which suggests that a short-term PES project has long-term positive effects.
