Opis

This volume comprises a selection of original contributions presented at a workshop held in Montpellier, France, in June 1997. The two main objectives of the workshop were, firstly, to bring together what is understood about the processes underlying agroforestry practice, and, secondly, to provide a forum to explore relevant models and modelling approaches. The workshop was also able to play a role in examining the agroforestry systems encountered in temperate and Mediterranean areas, including both traditional and more innovative agroforestry practices. The main aspects discussed were: ecological interactions amongst components, environmental impact, economics and policy modelling.
