GAEC les rocs - Employing agroecology in Vandée

GAEC Les Rocs, 2022 (c) Communauté de Communes de Pouzauges
Area characterisation: 

The Pays de Pouzauges local authority grouping is located in the Haut-Bocage in the eastern Vendée and consists of 10 communes with a total population of 23 000. In 2019 it was recognised as a « Territory Committed to Nature » (TEN) by all the members of the Regional Biodiversity Collective including the Pays de Loire Region. One of the key actions of the TEN process is the sustainable management of agricultural and forest areas, for example through the implementation of innovative agroecology operations. The sustainable management plans for the bocage raised farmers’ awareness of the roles of the bocage landscape and good management practices. In the framework of the Nature 2050 programme, GAEC Les Rocs is involved in the Pouzauges Bocage project, which is divided into four main operations: GAEC Les Rocs, GAEC La Niro (cattle farming), a demonstration of natural regeneration on a 1.25-hectare plot at Les Echardières and the transition from dying chestnut trees to a diverse high forest at La Fromentière. The farmers of the GAEC Les Rocs have been committed for several decades to adapting their practices to emerging environmental and societal issues in order to improve their autonomy and resistance to climate risks. The organic farm extends over 182 ha and combines dairy cattle, fodder crops (maize, dredge corn, alfalfa, clover) and field-grown vegetables. Trees in all forms (hedges, intra-field agroforestry) are a central element in their strategy for maintaining the long-term performance of the farming system. The first hedges were planted in the mid-1990s, resulting now in a hedge density of 160 linear meters per hectare. In addition, since 2017, rows of trees have been planted between plots in pasture areas. The project thus reflects the historical continuity of the actions undertaken throughout the Pays de Pouzauges.

Objective: 
  • For adapting to climate change : conserve the quantity and quality of the water downstream of catchment areas and consolidate the resistance of forest habitats to the effects of climate change.
  • For biodiversity : conserve the biological richness of the soil and reduce the pressure of forestry on the soil.
  • For the local area : enhance the bocage landscape, integrate the project in the Territory Committed to Nature (TEN) process and strengthen the resistance of the grazing systems.
Actions: 

Begun in 2020, the works consisted in :

  • Planting 333 trees of various species (Holm Oak, Sweet Chestnut, Wild Cherry, Almond, Walnut, Field Maple, Hornbeam, Service Tree, Chequer Tree, Alder, etc.) in 1188 ml of rows between plots and reinforcing existing rows. The trees are planted at 8-metre intervals with the rows 30 metres apart in order to leave room for agricultural machines to pass between them. The planting operation extended over a total surface area of 18 ha.
  • Protecting the saplings from wild animals (chestnut wood stakes) and drought (mulching with shredded wood).
Potential impacts/benefits: 

BENEFITS REGARDING TARGETED ADAPTATION ISSUES

  • Increasing the resistance of the farming system to climate hazards : protecting the fields and cattle from increasingly and intense frequent droughts and very high temperatures.

OTHER BENEFITS

  • Protection of agricultural plots from desiccating winds.
  • Creation of carbon sinks and therefore mitigation of climate change.
  • Improving grazing quality by means of shady areas and thus the health of the herd.

BENEFITS FOR BIODIVERSITY 

  • Creating refuges for beneficial organisms and birds : enabling the return of field birds and small raptors and enhancing the habitat network by means of new ecological corridors.
  • Fertilising the soil.
  • Diversifying the tree species by selecting those most resistant to droughts.
  • Restoration of the bocage landscape to improve the well-being of inhabitants and the attractiveness of the local area for tourism.
  • Development of tree production on the farm, enabling the associates to save money on firewood and animal bedding while diversifying their sources of income. For example, the shredded wood produced is used in the collective boilers of the Pays de Pouzauges local authority grouping.
  • Integration of the GAEC in a territorial ecosystem restoration process led by the local authority.
