Defining Agroecology

                            Agroecology is the science linking agricultural practices to their effects on ecosystems, and back. Pollination and biocontrol are prominent examples of the way agriculturally productive fields and pastures are linked to natural processes, and to the surrounding environment. Agroecology is linked to the name of Prof. Dr. Teja Tscharntke, in Germany, in Europe, in the world. When he retired, his colleagues and (former) PhD researchers produced this Festschrift. It discusses examples of Prof. Tscharntke's own scientific legacy, work inspired by him and his work, and outlooks to what is yet to come in this field. While primarily a celebration of an extremely successful and influential career, this volume also is an interesting read of what is currently discussed in the field of agroecology and adjacent disciplines.
