Land degradation from soil erosion has been considered by many to
be a problem of significant proportion, affecting some 30 50% of
the earth's land surface. At the time of the first publication of
this book in 1993, estimates indicated that 10 15 million hectares
of land were being lost each year through erosion and salinisation
from irrigation and that at such a rate of loss, topsoil reserves
on most sloping lands would be depleted within two hundred years.
Since humankind's dependency on the land for food is almost total,
soil erosion represents a real threat to the security of our food
supply. The need for the immediate conservation of the world's soil
resources is therefore clear. As part of the response to this need,
the International Union for the Conservation of Nature's Commission
on Ecology convened a special working group to consider the problem
of world soil erosion and to propose practical solutions for soil
conservation. This important book presents the outcome of their
work.
