Term (also field consolidation, land consolidation, land consolidation, reallocation) for all measures to make agricultural fields or plots of land that have been split up, mostly by inheritance, more suitable and cost-effective for cultivation by combining them. In the second half of the 20th century, an extensive state-controlled land consolidation programme was carried out in Germany for winegrowing. From the early 1960s onwards, more than half of the vineyard area in western Germany was restructured. There were many improvements through better access roads, better workability and better water drainage. Many fragmented estates were merged, thus reducing production costs.
