Such studies may yield exaggerated estimates of total soil loss.

First, there are few resources in developing countries to measure soil loss.

The central issue here is the assumptions about future agricultural technology which are made when assessing tolerable soil losses.

If such advances are to be made and put into practice by the people working the land, then higher soil losses can be 'tolerated'.

And again, since no erosion research data were collected, their effects on soil losses are unknown.

An effective and aesthetic facing to prevent soil loss between the nails can be designed using plant roots.

Effective erosion controls are important techniques in preventing water pollution and soil loss.

It has taken on new urgency for a variety of reasons, like climate change and soil loss.

There are the problems of soil loss and subsidence to contend with.

Sugar-cane farming causes such soil loss that many areas can survive no more than 15 or 20 years.
