The symposium In the next decades, agriculture will have to cope
with an ever-increasing demand for food and raw basic materials on
the one hand, and with the necessity to use resources without
further degrading or exhausting the environment on the other hand,
and all this within a dynamic framework of social and economic
conditions. Intensification, sustainability, optimizing scarce
resources, and climate change are among the key issues. Organized
thinking about future farming requires forecasting of consequences
of alternative ways to farm and to develop agriculture. The
complexity of the problems calls for a systematic approach in which
many disciplines are integrated. Systems thinking and systems
simulation are therefore indispensable tools for such endeavours.
About 150 scientists and senior research leaders participated in
the symposium 'Systems Approaches for Agricultural Development'
(SAAD) at the Asian Institute of Technology (AIT), Bangkok,
Thailand, in December 1991. The symposium had the following
objectives: - to review the status of systems research and modeling
in agriculture, with special reference to evaluating their efficacy
and efficiency in achieving research goals, and to their
application in developing countries; - to promote international
cooperation in modeling, and increase awareness of systems research
and simulation. The symposium consisted of plenary sessions with
reviews of major areas in systems approaches in agriculture, plus
presentations in two concurrent sessions on technical topics of
systems research. Subjects of studies were from tropical and
temperate countries.
Approaches to research on the causes and impacts of soil erosion
have changed significantly over recent years. Whereas biophysical
research traditionally utilized small, carefully-managed erosion
plots, models and methods are now available to study impacts of
broad scale management on the hydrology and water quality of
catchments and even river basins. Corresponding research tools have
been developed for social and economic analysis at the household,
farm and community levels. This book reviews the latest
developments in such soil erosion studies. These are considered on
a matrix of scales, from plot to river basin, and from farm to
national policy. Some chapters review background issues while
others consider specific methods. Conclusions of working groups are
presented in another chapter. The book is based on papers presented
at a workshop held in Indonesia in November 1997, and includes
authors from Europe, America, Australia and Asia, as well as from
several of the CGIAR centers.

The degradation of land and water resources resulting primarily
from agricultural activities has had enormous impact on human
society. In order to alleviate this problem, an advanced
understanding of the state of our resources and the process of
degradation is needed. "Conserving Land, Protecting Water" includes
an overview of existing literature focusing on global patterns of
land and water degradation and discussions of new insights drawn
from successful case studies on reversing soil and water
degradation and their impact on food and environmental security.
This book is based on a workshop held in Zimbabwe, May 1999,
organized by the Department of Research and Specialist Services
(Zimbabwe) and the International Board for Soil Research and
Management (IBSRAM). Reviewing the current state of knowledge on
and the practical aspects of the management of Vertisols in Africa,
this book also includes comparative chapters covering other parts
of the world, such as India, Australia and Texas (USA).
