'The book is well-written and makes a significant contribution to the development of the principles and practices of dealing with agri-environmental problems. It is of relevance to a wide circle of readers, including researchers and politicians but also students and others concerned with agri-environmental issues.' - Stefanie Engel and Ulrike Grote, Quarterly Journal of International Agriculture '. . . the book has the potential to provide something for everyone.' - Stefan Bäckmann, European Review of Agricultural Economics Although the history of the Common Agricultural Policy (CAP) is dominated by a process of centralisation, growing pressures to integrate agri-environmental problems into the CAP have revealed the need to embrace decentralised approaches in an efficient federal structure.
