Ecosystem services and biodiversity in Europe

One of the key messages of this report is that, although European ecosystems can give a wide range of services, managing land primarily to deliver one service will reduce its capacity to deliver other and equally valuable services. This trade-off is particularly important for farming systems, where ...
