With help from the
federal and state governments many German vineyard owners were able to redesign and replant their vineyards to optimize maintenance and harvesting. Several vineyards also took the opportunity to upgrade their plantings from the lower-quality
Müller-Thurgau grape to the high-quality
Riesling vine. Some wine areas also improved the roads and access to their vineyards to increase
tourism potential. In some cases, parcels of land that were spread out over different areas were reallocated among vineyard owners to reduce production cost. In areas where wine is not produced, it is normally the size of the parcels and the quality of the infrastructure which are improved through land consolidation. Later on, environmental protection and community and regional development became important goals. affects owners and leaseholders of the affected land, as well rightsholders of the land lots, municipalities, public agencies and farmer associations. The participants may incorporate to a body of public rights which is controlled by a public authority and called a , best translated as "participant association". According to the these bodies may form a union within a state. All unions have been integrated into the , the federal alliance of participant associations. The outcome of a should lead to the greatest benefit for the participants but also for the general public. Public roads and infrastructure such as channels are built, creeks are straightened, land improvement is carried out, and the landscape is rearranged according to regional development and country planning. Thereafter roads and infrastructure are normally in possession of the municipality. It is desirable that the estates of land are distributed as homogeneously as possible among the participants. As this is not always possible, legal actions against the redistributions are common. ==Negative example==
