This Book contains the abstracts of papers that were selected for presentation at the
Foreward 1st World Congress of Agroforestry (WCA), 2004. Except for the abstracts of 29 invited
presentations for seven symposia included in the beginning of the book, all were
Preface voluntary submissions for oral or poster sessions.
Sponsors In preparation for the Congress, we solicited potential participants to submit abstracts
for presentation during oral and poster sessions. The response vastly exceeded our
Search Abstracts expectations: we received more than 800 voluntary submissions from all over the
world. The abstracts were sent to the respective WCA session organizers for their
Author Index scrutiny and decision on their acceptability for oral or poster presentations. Although
the session organizers were requested to be as accommodative as possible in making
Org. Committees their decisions, quite a few abstracts had to be rejected as they were deemed
unrelated to agroforestry even by the broadest definition of the term. The authors
CD Tech Support were then given the opportunity to submit revised and updated abstracts. The final
selected abstracts were then edited for uniformity in length (maximum 250 words),
presentation format, and language. Because of the volume of work that had to be
accomplished within a tight time schedule, the edited versions could not be sent back
to the authors for their approval; we request the authors' understanding and
forbearance for this. At the time of sending this to the press, some authors'
attendance in the Congress and presentation of their work are still uncertain because
of financial and administrative reasons. Nevertheless, all abstracts processed as above
are included in this book with the authors' approval.
Undoubtedly, this Book of Abstracts represents the current state of information and
knowledge in agroforestry worldwide. Several of these presentations will be developed
as full-length journal articles for the special issues of thematic journals that will feature
Congress presentations (at the time of this writing, arrangements have been confirmed
for special issues of seven scientific journals). But, for the majority of the abstracts
that may not be published as professional and academic publications, this Book of
Abstracts will remain the only source of reference. Thus, we believe that this book will
be a valuable resource for future use. The book will also be made available to
Congress participants as a CD, and the abstracts will be posted on the Congress Web-
site (http://conference.ifas.ufl.edu/wca), and retained for several months after the
Congress.
Compiling this Book of Abstracts involved the efforts of a number of individuals. I wish
to express my sincere appreciation to my colleague Dr. Samuel Allen of the Center for
Subtropical Agroforestry (CSTAF), University of Florida (UF), who edited the final
abstracts for technical language, length, content and style. Other CSTAF colleagues,
notably Dr. Michael Bannister and Ms. Julie Clingerman, provided considerable support
and assistance to Dr. Allen in accomplishing this task. Special thanks are due to the
Congress Coordinator, Ms. Mandy Stage, who with the assistance of Ms. Tracy Nininger
and others at the UF Office of Conferences and Institutes, has handled effectively and
tirelessly the myriad of logistics and communication associated with the development
of this Book, including the final proofing and printing. Finally, I sincerely thank all the
authors and session organizers, without whose cooperation and timely inputs this
publication would not have been possible.

Preface

Home
This Book of Abstracts represents the collective endeavor of hundreds of researchers,
Foreward extensionists, landowners, students and others interested in agroforestry around the
world. We trust that it will be useful as a source for the state-of-knowledge and
Preface practice of agroforestry.
Sponsors The Congress program consists of eight symposia (with invited contributions) and 32
sessions (with voluntary presentations). Each session and symposium has four oral
Search Abstracts presentations (except for the symposium on "Public/Private Partnership in
Agroforestry," which is a panel discussion with no formal presentation planned).
Author Index Therefore, the arrangement of this Book is as follows:
Symposia abstracts (29) are arranged alphabetically by the first author's last name in
Org. Committees
the following topic categories:
CD Tech Support
I. Agroforestry and Food Security
II. Biodiversity
III. Carbon Sequestration
IV. Ecological Basis of North American Agroforestry
V. Technology Transfer
VI. Trees and Markets
VII. Water Issues
Additionally, the 717 voluntary abstracts of oral and poster presentations at the 32
sessions are arranged alphabetically by the first author's last name within each of the
following six broad groups:
I. Adoption, Food Security and Poverty Alleviation
(Includes topics related to sessions on: Agroforestry Adoption (Tropical and
Temperate), Agroforestry and Food Security, Agroforestry for Health and Nutrition
(AIDS/HIV), and Poverty Alleviation and Sustainability)
II. Biodiversity, Ecoagriculture and Homegardens
(Includes topics related to sessions on: Biodiversity, Ecoagriculture, Medicinal and
Aromatic Plants in Agroforestry, and Tropical Homegardens)
III. Biophysical Aspects
(Includes topics related to sessions on: Biophysical Interactions, Carbon Sequestration
and Landscape Ecology in Western Europe, Carbon Sequestration and Environmental
Benefits, Decision Support Tools, Environmental Amelioration, and Climate Change)
IV. Economic and Social Aspects
(Includes topics related to sessions on: Economic Analysis, Land Tenure and Gender
Issues, Local Agroforestry Knowledge in Global Context, Policy and Institutions,
Scaling up of Agroforestry Benefits, and Mechanization)
V. Semiarid Regions, Soil Fertility and Agroforestry Education
(Includes topics related to sessions on: Agroforestry in Semiarid Regions, Land
Owners' Session, Small Farm Soil Fertility Management Strategies, and Agroforestry
Education)
VI. Tree Domestication and Management

Preface
(Includes topics related to sessions on: Managing Genetic Diversity, Short-rotation
Woody Crops, Phytoremediation, Tree and Component Management, Tree
Domestication, and Trees in Fragmented Landscapes)
As mentioned in the Foreword, the authors' original abstracts were edited for
uniformity in format, 250-word limit, spelling, scientific nomenclature, and overall
readability. Making these modifications, and that too without having the opportunity
of discussing them with the authors (for reasons of time constraints) has been a
difficult and at times painful task. In doing so, I have tried to retain the technical
content and ensure readability of each abstract as much as possible; for any
inadvertent deletions or other deficiencies in this process, I beg the understanding
and forbearance of the authors. In spite of the above difficulties, I have enjoyed the
task and gained considerable insight into the current state of agroforestry in the
world.
I thank Professor Nair, the Congress Chair, for entrusting me with this task; and Dr.
Michael Bannister and Ms. Julie Clingerman of CSTAF and Ms. Mandy Stage, the
Congress Coordinator, for their constant assistance and support in fulfilling this task.
