The project ARVA of the Walloon Region aims setting up the monitoring of arable land. The project proceeds in four phases:
(i)the development of a soil monitoring which complies with the requirements of both the European regulation and the Walloon agriculture practices;
(ii) the inventory of existing knowledge on the quality of soil in the Walloon Region and their relevance at Regional scale;
(iii)the best estimate of the accuracy needed to detect evolutions in soil. To do this, test sites will help to
validate the methodology used;
(iv)an analysis of the strategies for structuring a future monitoring network. This strategy depends on the threat taken into consideration, as the selected
options shall not compromise future needs for monitoring.
