This book focuses on the global effects of land degradation, but
emphasizes other important levels of land degradation: at the field
level, it may result in reduced productivity; at the national
level, it may cause flooding, and sedimentation; and, at the global
level, it can contribute to climate changes, damaging
bio-diversity, and international waters. The effects on climate
changes are explored, and the report questions the extent to which
land degradation on agricultural land, affects climate change. Does
it increase emissions of greenhouse gases? Does it affect land's
capacity to serve as a carbon sink? Can appropriate management
enhance both land's productivity, and its capacity to store carbon?
The carbon cycle in soils is analyzed, indicating land degradation
is likely to reduce the ability of soils to serve as carbon sink,
and release stored carbon into the atmosphere, and, bio-diversity
effects are likely to be adverse. Global benefits of land
degradation control, include afforestation, to allow increased
carbon sequestration, and provide adequate bio-diversity habitats;
and, community-based wildlife management, can provide alternatives
to some marginal areas. Although integrating global dimensions into
land degradation control projects, may reverse the field level, or
national problems it is causing, difficulties and constraints will
likely contribute to the failure of these projects.
