Factors studied

Positive effects

Negative effects

- Need for local availability of seeds.

- Decrease in insecticide applications.

- Reduction of irrigation thanks to the limitation of crop evapotranspiration through hedges.

- Increase in operating costs and variable mechanization depending on the facilities put in place and their management.

- Windbreak effect of hedges and barrier effect against pests.

- Limitation by hedges of pollution generated by fertilizing and phytosanitary inputs.

- Protection against soil erosion.

- Improvement of soil fertility in the case of sowing under permanent cover.

- Decrease in cultivated area.

- Increased competition between the edge of the plot and the development.

- Reservoir for certain pests.

- Less pesticide residues.

- Less damage to products because fewer pests.

- Increase in functional biodiversity.

- Reduction in the transfer of phytosanitary products with the reduction in the use of insecticides.

- Reduced fuel consumption if facilities are located on non-productive areas that were previously weeded with herbicide or mechanically.

- Fuel consumption for planting, harvesting or destroying relay plants or maintaining hedges.
