Ecosystem services are the direct and indirect contributions of ecosystems to human well-being. Intensification of European agriculture has boosted crop yields, a provisioning ecosystem service, contributing to food security and economic development. However, this has been at the expense of the delivery of various regulating ecosystem services and biodiversity. Nature-oriented measures have the potential to combine agricultural production with other benefits. Via a meta-analysis, this study shows that hedgerows, grass strips and extensive grassland management have the potential to deliver multiple regulating ecosystem services and enhance biodiversity in the agricultural landscape but that there can be a negative impact on crop yield. Field observations on Flemish fields confirmed the enhancement of several ecosystem services and biodiversity aspects, but also revealed that the simultaneous delivery of a broad range of benefits is not always the case and that there are trade-offs in the extent to which some services can be provided simultaneously. These trade-offs are strongly linked with management and context. An economic analysis was performed to assess the economic impact of implementation of hedgerows and alley cropping on a typical farm in Flanders and has shown that in almost all cases, subsidies make up for the income reduction resulting from arable land loss and lower crop yields. This study aims to contribute to the valuation of the benefits that can be obtained from the implementation of nature-oriented measures in agriculture and to the development of a holistic assessment framework for multifunctional agricultural practices.
