This book is
organized into two sections. The first section covers three major aspects, viz.,
an understanding of patterns of land degradation and desertification for
developing mitigation strategies, land-atmosphere interaction from response of
land cover to climate change effects of Karst rocky desertification. The last
section dwells on the relationship between soil degradation and crop production
and an examination on how land degradation impacts the quality of soil in
communal rangelands.
This class
presents the application of principles of soil mechanics. It considers the
following topics: the origin and nature of soils; soil classification; the
effective stress principle; hydraulic conductivity;
stress-strain-strength behavior of cohesionless and cohesive soils and
application to lateral earth stresses; bearing capacity and slope stability;
consolidation theory and settlement analysis; and laboratory and field methods
for evaluation of soil properties in design practice.
