his first book volume collects country reports produced by the AE4EU Horizon 2020 project and the European Association Agroecology Europe which involved a large number of organisations, as well as more than 25 "mappers" who conducted the work in different European countries. Among them were many members of the Agroecology Europe Youth Network (AEEUYN).

The different volumes of the book series offer an illustrative state of the art of agroecology in Europe by synthesizing and providing key information on the common understanding of agroecology, as well as its development at the European level.

To scale up agroecology, this first book volume provides critical information and analysis of the development of agroecology in different contexts, which is very much needed as a necessary step to attain larger insights about the state of the art of agroecology, as well as to support its expansion and use at the policymaker level.

Documenting the development of agroecology in 13 European countries (Albania, Austria, Bosnia, Bulgaria, Croatia, Germany, Greece, Italy, Kosovo, Malta, Montenegro, North Macedonia, and Romania), this volume describes 112 initiatives, examples, cases, and programmes linked to agroecology, and the development of agroecology in these European countries as well as the diversity of use of the concept.
