The main threats to soils are: extension of urbanization, acidification, accumulation of pollutants, nitrate in groundwater, loss of organic matter and deteriorating soil structure, soil compaction, and erosion. The latter is especially important in southern EC countries. Differences in the approaches adopted by different countries reflect differences in the nature and perceived seriousness of soil problems and the nature of the legislatory system. In particular, differences in the approaches of the Netherlands and the UK are discussed. The concept of ‘soil quality’ is discussed in relation to these two approaches. Suggestions are given for an ecologically based soil protection policy. This paper discusses current soil protection policies and their development in the EC, and the evolution of the associated concept of ‘soil quality’. It does not deal in any detail with the restoration of soils which have been degraded by the inadequacy of past policies or their implementation. Emphasis is given to northern EC countries because they have been especially active in the development of policies which protect land and soils. |
