Therefore, a strategic policy framework is missing that would, in an integrated manner conceptualise soil issues (including common definitions on good status) set out priorities and targets define monitoring parameters and desired end points and define the role of different policy instruments in delivering good soil status. Of particular relevance for institutional compatibility are the market imperfections and the corresponding institutional adaptations. Under natural conditions - in climates where agriculture can be practiced - the soil is protected by vegetation and the rate of soil loss by erosion is very low.
