Soil degradation is a widespread problem in Africa resulting in
decreased agricultural productivity while demand for food continues
to increase. Degradation is caused by accelerated erosion,
acidification, contamination, depletion of soil organic matter and
plant nutrients, and salinization. The major cause of soil
degradation in Africa is uncontrolled and excessive grazing in the
savanna regions followed by deforestation and the use of
inappropriate and extractive farming practices. Perpetual neglect
of the health of soils in Africa can exacerbate the already serious
problems of food and nutritional insecurity and environmental
degradation. Food and nutritional security of the growing
population of Africa can only be achieved if degraded soils are
restored and soils of agroecosystems are managed prudently and
sustainably. Ignoring soils and taking the fragile, finite and
precious soil resources for granted is the principal cause of
poverty, hunger, and environmental degradation. The downward spiral
must be reversed through soil restoration measures based on
translating science into action. This book describes the soils of
Africa, processes of soil degradation, extent and severity of soil
degradation, and the impacts of degradation processes on food and
nutritional security. Features: Explores the extent and severity of
soil degradation in Africa Analyzes the cause-effect relationship
between anthropogenic activities and soil degradation Reviews
processes of soil degradation in Africa including erosion,
salinization, nutrient depletion, and decline of soil organic
matter Addresses the effect of climate change on soil degradation
in Africa. Explains how soil degradation causes food and
nutritional insecurity Part of the Advances in Soil Sciences
series, this volume is specifically devoted to the processes and
factors that cause soil degradation and the challenges and
potential for remediation and restoration of soil health in Africa.
