Just five years ago, it was generally believed that the number of
food insecure people in the world was on continuous decline.
Unfortunately, widespread soil degradation along with resistance to
recommended agronomic practices, and little attempt to restore
degraded soils have conspired with significant droughts (in regions
that could least tolerate them) to swell the ranks of the food
insecure to over a billion people. The U.N. Millennium Development
Goals' intent to halve hunger by 2015 will not be realized. Food
Security and Soil Quality brings together leading experts from
across the world to provide a concise and factually supported
exploration of the problem at hand and the critical steps needed to
reverse it. Edited by Rattan Lal, and B.A. Stewart, two of the
world's most respected soil scientists, this important work -
Assesses farming systems and food security in Sub-Saharan Africa,
with special emphasis on land degradation Examines concerns with
and approaches to soil quality management in Brazil and China
Details achievable methods for improving soil quality for
sustainable production Provides an insightful comparison of
temporal changes in agricultural systems productivity in Punjab,
India and Ohio Discusses the human dimension of the crisis
including the influence of culture and spiritual beliefs Dr. Lal
himself writes that despite the existence of scientific data on
sustainable management of soil and water resources, problems of
soil and environmental degradation have persisted and have been
aggravated. And that these problems are rooted in land misuse and
soil mismanagement. This book does provide policymakers and others
with an understanding of the depth, complexity, and immediacy of
this crisis, but more than a call to action, it also offers soil
scientists working in this area with an understanding of what is
being done and what needs to be done. Most importantly, this book
helps us understand that the situation is not beyond remediation
were we to act with great resolve and a sense of urgency. A tree's
leaves may be ever so good, So may its bark, so may its wood; But
unless you put the right thing to its root, It never will show much
flower or fruit. - from Leaves Compared With Flowers, by Robert
Frost
