Productive ecosystem services and collective management: Lessons from a realistic landscape model

Previous works based on the simulation of stylized landscapes with homogeneous farms have concluded that farmers would benefit from the coordinated landscape-scale management of ecosystem services. Here, we examine such benefits in a realistic landscape (Brittany, France), with diversely fragmented farm territories and locally validated field-based ecological functions (the abundance of a generalist pest-predatory insect). We test whether such properties modulate the previous results by simulating several management strategies of biological control with an agronomic-ecological-economic landscape model. We find that, if landscape-scale management improves the collective benefits, some farmers lose by collaborating. Due to the heterogeneity of farms, the stability of the collective action is rarely satisfied at the landscape scale: the probability that the collective management of productive ecosystem services occurs is 15% in our case.
