In this project we aim to analyse the science-policy gap for four different regions, namely Aceh, Guianas, Chaco-Pantanal and Zambezi. We focus on science related to ecosystem services and economic valuation on the one hand and conservation policies on the other hand. A rapid literature assessment was conducted, revealing well and understudied ecosystem services per region as well as across all the four regions. An exploration of the policy environment through interviews with site specific experts from WWF in combination with literature provided insights in the policy field. The results reveal success cases, factors contributing to success, and recommendations on how the science-policy gap could be closed in the future. The project was commissioned by WWF to support the Sustainable Resources Joint Solutions (SRJS) project goals.
