Desertification has occurred worldwide. The biophysical and
socio-economic complexity of this phenomenon has challenged our
ability to categorize, inventory, monitor and repair the condition
of degraded lands. One of the most important distinctions to be
made in relation to land degradation is between cultivated land
used for annual crop production and rangelands'. Grazing by
free-roaming livestock is the traditional primary use of the
world's rangelands. However, there is growing recognition of the
importance of these vast acreages for wildlife habitat, hydrology
and ground water recharge, recreation and aesthetics. This text
focuses on the desertification of rangelands and explores
processes, problems and solutions. Chapters in the first section
evaluate interactions between natural' and human-induced
disturbance regimes, thresholds, and non-linear change with respect
to vegetation, hydrology, nutrients and erosion. Chapters in the
second section examine socio-economic constraints and approaches
for preventing and reversing degradation. The book provides a
contemporary, process-oriented perspective on rangeland degradation
of value to students, policy-makers and professionals alike.
