Landscapes, as value recognition identity fundamentals are fragile because of the cost of maintaining them, particularly for wine-growing regions with low added value.

The terraces, fragile architectural components, illustrate this complex aspect of heritage. A lack of maintenance, set-aside land and erosion mean that the slope slowly returns to its natural profile. For wine-growers, it is easier to concentrate on the vineyards on the plain. All the same, vines, on condition that soil management is adapted, limit the spread of fires, unlike scrubland filled with broom and junipers.
In addition, terraces are often positive factors in wine quality, but this must have enhanced value to support the extra operating costs. Switzerland and Germany have managed to encourage the maintenance and even the replanting of vineyards in these sensitive zones through financial aid.

Initiating, formalising and brining a collective project to concrete fruition also imply a strong involvement and decompartmentalisation of the players in the landscape context (agriculture, territorial authorities).
