What is agroecology?
Agroecology is a scientific subject stemming from the crossing of three disciplinary groups: agronomic sciences (agronomy and animal breeding), theoretical ecology applied to agrosystems, and social and economic sciences (sociology, geography, economy).[1] It aims to analyze, through these three scientific approaches, the management of an βagro-eco-systemβ. There are different goals as to maximize a sustainable production in agriculture, preserve capacities to regenerate resources, and to supply humans with multiple services (such as water conservation, control of pests, pollination,…).[1]

What about the results in the field?

One of the objectives of agroecology is to decrease the use of pesticides and insecticides to fight the adventitia and pests. Their over-use is the origin of the many resistances. The principle of agroecology is to rely on ecological processes to fight against these organisms, by using biological predators of the noxious ones or by focusing on the complementarity of some crops to keep them away. The experimental unit at Γpoisses (near Dijon, Burgundy) has been working for 10 years in the agroecology field, specifically on systems of culture with integrated protection.[5] The integrated protection is based on the combined use of a set of cultural techniques: diversification of crops (legumes) and their successions, addition of spring cultures (barley, sunflower, lupinus)… The prospective results over 10 years show that it is indeed possible to develop a strategy of control of the adventitious, while reducing drastically the use of weed-killers. The experiment has yet to be pursued by developing new criteria, such as biodiversity measures.
