Congratulations to the work on this important topic so far!
The paper presents a very good overview about important topics related to FSN based on literature and case studies. The team has been able to synthetize very valuable information in the short time frame available. Many important topics are already included, such as relationship with other ecosystem services, trade-offs between sustainable forestry and agriculture, climate change and governance aspects. Many illustrative case studies have been collected in form of boxes. However, it is not always clear if and how experiences from one case study can be transferred to another context. Due to given time constraints, the focus on cross cutting key questions is not always visible, especially in the conclusions section. For decision makers a higher level of specificity might be useful, e.g. by being more spatially explicit, or indicating which policy instruments related to forests have been effective under certain contexts (e.g. PES for water, REDD+, protected areas etc.).
Some more observations are attached. Good work so far, all the best!
