This publication deals with soil erosion and sedimentation. Soil
erosion and associated sediment deposition are natural
landscape-forming processes that can be greatly accelerated by
human intervention through deforestation, overgrazing, and
non-sustainable farming practices. Soil erosion and sedimentation
may not only cause on-site degradation of the natural resource
base, but also off-site problems- downstream sediment deposition in
fields, floodplains and water bodies, water pollution,
eutrophication and reservoir siltation, etc. -with serious
environmental and economic impairment. There is an urgent need for
accurate information to quantify the problem and to underpin the
selection of effective soil-conservation technologies and
sedimentation-remediation strategies, including assessment of
environmental and economic impacts. Existing classical techniques
to document soil erosion are capable of meeting some of these
needs, but they all possess important limitations. The quest for
alternative techniques for assessing soil erosion, to complement
existing methods, directed attention to the use of environmental
radionuclides, in particular fallout as tracers to quantify rates
and establish patterns of soil redistribution within the landscape.
The concept of a project on the use of environmental radionuclides
to quantify soil redistribution was first formulated at an Advisory
Group Meeting convened in Vienna, April 1993, by the International
Atomic Energy Agency (IAEA).
