Book excerpt: Ecostacking is a new concept and approach which aims to maximize the benefits of ecosystem service providers in cropping systems to help achieve the goal of long-term sustainable agriculture and food production. The term "ecostacking" means combining synergistically the beneficial services of functional biodiversity from all levels and types. It is a comprehensive approach, where the various ecosystem service providers are fully integrated with the rest of the cropping system including agronomic practices. It is an approach which goes beyond conventional Integrated Pest Management practises, and attempts to take advantage of all the functional biodiversity of a system. The Concept of Ecostacking is the first book in a series which introduces ecostacking concepts to the reader and explores how this approach can be used in a variety of ways and in different cropping systems. The book defines this new concept and shows, using illustrative case studies from around the world, how ecostacking principles can be successfully employed in cropping systems in the open field, in greenhouses and in forestry. This book has been written and edited by the world's leading experts in this new and exciting endeavour, and is a must-read for everyone with an interest in developing sustainable crop protection systems and ecosystem management.
