Policies for a Sustainable Use of the Soil Resource

• National – USA, Germany, United Kingdom, etc….

• Trans-national (regional)– EU Thematic Strategy for Soil Protection,

Alpine Convention, Euro-Mediterranean Partnership

• Global– MEA’s: UNFCCC, CBD, UNCCD

The way forward

• Improve our policy relevant soil information.

• Delineate areas at risk of soil degradation by the various threats.

• Implement existing legislation and MEA’s.

• Monitor the impact of existing legislation on soil protection.

• Develop (if necessary) specific legislative instruments for soil protection.
