What does agroecology suggest ? Next to the theoretical agroecological

principles, we present illustrative examples from farming practices, through the

food system, up to the way of carrying agricultural research and education.

In both wildflower strips (WFS) and oilseed rape crops (OSR), the increase number of pests is followed by an increase of their parastoid natural enemies. It is expected that the floral ressource helps to support the parastoid populations.

strips to control pests

CS treatment negatively impact winter wheat final yield but improve protein rate. The CS applied in july was similar to a mature walnut agroforestry plantation (84 tree/ha, 40cm DBH), (Molto et al., 2014).

studied ES by scientific literature
