A successful and justified multiannual afforestation programme requires a good insight into the objectives and awareness of the constraints of the new forests, a planning strategy and a thorough research on the missing aspects. Socio-economic constraints mainly relate to social aspects of the farmers involved, who must be assured of a viable income. Therefore the new forest types and silvicultural systems should produce a reasonable return, without neglecting however the global multiple use objective. Planning has to deal with specific goals, the area of new forests, the location and size, accompanying measures and a time scale.
