This paper presents the various environmental parameters and sedimentological processes that contribute to the occurrence and enhancement of the problem of sandencroachment in Kuwait and discusses concepts relevant to control measures.
The impact of grazing on spatial variability of humus profile properties in a grass-encroached Scots pine ecosystem
Grazing is often used in management of grass-encroached Scots pine (Pinus sylvestris) forests in The Netherlands, because it is thought to increase diversity of vegetation and humus profiles. To test this hypothesis, two 1 ha plots in a primary pine
stand on drift sand were grazed for 7 years at high and moderate intensities. The humus profiles of these 2 sites and of a control site were sampled at various scales to assess changes in grass biomass, thickness of ectorganic horizons, organic matter
is left behind. They constitute a major erosion problem in the country. Other means of erosion are, however, equally as important in destroying vegetated andosol ecosystems, especially sandencroachment, but none is as distinctive on the landscape

A review of stream, dune and lake phenomena in several well-studied sectors of the Sahel indicates an informative record of repeated environmental change. Blowing sandencroached far into the now semi-arid savanna between approximately 20,000
was triggered by a massive sandencroachment (1660 AD) from 3 outwash sand-plains along the glacial River Far. The sand drift was sustained by dry northern glacial (katabatic) winds that drove the soil erosion. Frequent volcanic tephra fallouts and glacial river

Assessment of the effects of biophysical and anthropogenic factors on woody plant encroachment in dense and sparse mountain grasslands based on remote sensing data
This study assessed woody plant encroachment below potential tree line in the Central Pyrenees of Spain and the association of this encroachment with changes in land use. Remote sensing data from Landsat-5 Thematic Mapper (TM) from the mid-1980s
biophysical and anthropogenic factors that were significantly correlated with woody plant encroachment of dense and sparse grasslands. Distance to the nearest woody plant habitat (shrub or forest) was the most strongly correlated factor with woody plant
encroachment of both types of grassland. This factor explained 69% and 71% of the variance in models of dense and sparse grasslands, respectively. The observed changes in land cover indicated that land cover has become more homogeneous.

Deterioration of grazing and bush encroachment in commercial farming areas, and denudation through grazing and wood use in subsistence areas are described and assessed. - (AJC)
Soil–vegetation interaction on slopes with bush encroachment in the central Alps – adapting slope stability measurements to shifting process domains
along a chronosequence of green alder (alnus viridis) encroachment on the Unteralptal in central Switzerland revealed that shrub encroachment changes soil and vegetation properties towards an increase of resistance to run-off related erosion processes
