In densely populated areas, such as Flanders, serious conflicts arise due to the afforestation of agricultural lands. Roughly speaking, three sectors are involved: agriculture, forestry and nature conservation. These groups do not always share the same points of view. But even within the different sectors there are several subgroups with their own interests and approaches. Generally speaking, agriculture is strongly opposed, forestry has a relatively diversified meaning, whereas nature conservation is either opposed or in favour, depending on the region's biological value. The policy in this matter is not forest friendly. Legislation strongly hampers the afforestation of agricultural lands. Moreover the subject leads to a series of ecological problems, which have not really been considered up to now.
