Book Description
This volume contains a solid body of the current state of knowledge on the various themes and activities in agroforestry worldwide. It is organized into three sections: the Introduction section consists of the summaries of six keynote speeches at the 2nd World Congress of Agroforestry held in Nairobi, Kenya, in 2009; that is followed by two sections of peer-reviewed thematic chapters grouped as “Global Perspectives” (seven chapters) and “Regional Perspectives” (eleven chapters), authored by professional leaders in their respective agroforestry-related fields worldwide. A total of 130 professionals from institutions in 33 countries in both developing and the industrialized temperate regions of the world contributed to the book as chapter authors and/or reviewers. Thus, the book presents a comprehensive and authoritative account of the global picture of agroforestry today.

Book Description
The most complete, nonpartisan source of information on this hot agronomic topic available today, this book brings together a diverse group of papers and data to resolve the debate between sedimentologists and soil scientists and agronomists over whether the effects of soil erosion on carbon and atmospheric CO2 is beneficial or destructive. Divided into four sections, it offers data on how soil erosion affects soil, water, and air quality. Topics include mineralization rate, inundation, sediment deposition, and global warming potential, as well as carbon dioxide, methane, and nitrous oxide emissions, and the implications of soil erosion on the global carbon cycle and carbon budget.

Book Description
Did you know that you are more closely related to a mushroom than to a daisy? That dinosaurs are still among us? That the terms "fish" and "invertebrates" do not indicate scientific groupings? All this is the result of major changes in classification. This book diagrams the tree of life according to the most recent methods of this system.

Book Description
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.
