This book provides a quantitative analysis of the role of woody plants
in semi-arid regions, for the aSSessment of their benefits in
agrosylvopastoralland-use systems with productive and sus- tainability
objectives. The insights presented and conclusions drawn allow the
additional benefits of woody plants for specific climatic and physical
site conditions and land-use systems to be estimated. The Sahel and
Sudan zones in West Africa, on which the book focusses, represent
resource-poor conditions, whose ecological dynamics have been relatively
well studied. The role of woody plants in this region, as assessed in
this book, is extrapolated to other semi-arid regions, leading to
general conclusions on agroforestry's potential as an option for
sustainable land use in semi-arid regions. The origins of this book go
back to 1982, when the Club du Sahel requested that available data on
woody plants in the Sahel region be synthesised, to provide basic
information to enable better attention to be given to woody plants in
rural development programmes. We are grateful to the Club du Sahel for
this challenge. Various people contributed to studies used in this book.
The preliminary inventory of the data available was made by Frits Ohler;
later his work was continued by Franciska Dekker.
