Sammanfattning
1. The concept of ecosystem services (ES) has rapidly entered policy and planning agendas nationally and globally. However, its usefulness is hampered by, for example, insufficient understanding of underlying ecological processes and poorly developed and competing conceptual frameworks. 2. It is suggested that final ecosystem services, such as yield, can be partitioned into components describing contributions from ecosystems (regulating and maintenance ES as natural inputs) and human inputs. This conceptual framework is tested by examining the relative importance of farming system (conventional vs. organic, indicating human inputs, and management), landscape (field shape and landscape heterogeneity), and biological control of aphids by natural enemies (indicating a regulating ES) for barley yield on 10 fields in central Sweden. 3. Although biological control was related to increased yield, its contribution was relatively small (
