內容簡介：
Important ecosystem services that underpin agricultural yields, such as pollination andbiological control, are mediated by mobile organisms and depend on the availability of (semi-natural)habitats as well as their arrangement in the landscape. It has been suggested that coordinated orlandscape-scale management of habitat in a multi-farm landscape results in higher provisioning ofsuch ecosystem services compared to farm-scale management. However, to achieve optimal land-useunder coordinated management it is necessary to define rules on how to use land to optimizeaggregate benefits from ecosystem services. To this end, we aim to develop rules that characterizeoptimal solutions based on novel land-use pattern indices. To do this we model farmers'interdependencies through ecosystem services in an agent-based model (ABM) and optimize land-usepatterns at both the individual farm and landscape scales for comparison. We demonstrate that thecoordinated solution is characterized by a higher degree of habitat conservation generally and aconfiguration of habitat that is more dispersed rather than agglomerated. We test our rulescharacterizing optimal solutions on a range of assumptions about ecological parameter values andsuggest that such rules could be used to improve governance of ecosystem services in agriculturallandscapes.
