Agroecology as a science, a movement and a practice. A review

Agroecology involves various approaches to solve actual challenges of agricultural production. Though agroecology initially dealt primarily with crop production and protection aspects, in recent decades new dimensions such as environmental, social, economic, ethical and development issues are becoming relevant. Today, the term ‘agroecology’ means either a scientific discipline, agricultural practice, or political or social movement. Here we study the different meanings of agroecology. For that we analyse the historical development of agroecology. We present examples from USA, Brazil, Germany, and France. We study and discuss the evolution of different meanings agroecology. The use of the term agroecology can be traced back to the 1930s. Until the 1960s agroecology referred only as a purely scientific discipline. Then, different branches of agroecology developed. Following environmental movements in the 1960s that went against industrial agriculture, agroecology evolved and fostered agroecological movements in the 1990s. Agroecology as an agricultural practice emerged in the 1980s, and was often intertwined with movements. Further, the scales and dimensions of agroecological investigations changed over the past 80 years from the plot and field scales to the farm and agroecosystem scales. Actually three approaches persist: (1) investigations at plot and field scales, (2) investigations at the agroecosystem and farm scales, and (3) investigations covering the whole food system. These different approaches of agroecological science can be explained by the history of nations. In France, agroecology was mainly understood as a farming practice and to certain extent as a movement, whereas the corresponding scientific discipline was agronomy. In Germany, agroecology has a long tradition as a scientific discipline. In the USA and in Brazil all three interpretations of agroecology occur, albeit with a predominance of agroecology as a science in the USA and a stronger emphasis on movement and agricultural practice in Brazil. These varied meanings of the term agroecology cause confusion among scientists and the public, and we recommend that those who publish using this term be explicit in their interpretation

Comparaison de populations de carpe commune (Cyprinus carpio) à taille commerciale : intérêt d'une approche globale

Six populations de carpe commune (Cyprinus carpid) ont été comparées sur la base de quatre critères : morphologie, génétique, rendement de transformation et aspect des filets. Les provenances géographiques des différents lots étudiés correspondent aux principales régions de production piscicole françaises : Dombes, Forez, Brenne, Allier, Lorraine et Poitou-Charentes. Une discrimination géographique des populations est possible mais elle repose sur une approche globale intégrant l'ensemble des paramètres. Les différences semblent essentiellement liées aux conditions environnementales et permettent de distinguer les lots issus des régions où l'élevage est plus intensif et traditionnellement centré sur la carpe (Dombes, Forez, Lorraine) et les lots correspondant à un élevage plus extensif et davantage orienté vers le marché du repeuplement (Allier, Brenne, Poitou-Charentes)

De la parcelle au poisson d’étang

International audienceThe wetland aquaculture-agriculture system of Dombes, France is based on the integrated management of its fishponds and agricultural plots. Surface runoff and subsurface flow connected to ditches allow drainage of the soil and contribute to fill the ponds. Pond exposure to pesticides is controlled both by land use and runoff contribution. A set of fishponds was selected according to their exposure to pesticides from cultivated areas. Agricultural practices were analysed and the pesticides used were precisely identified. Runoff, pond water, pond sediment and carps were sampled and analysed for pesticide residues. Results indicate that non point source pollution affects exposed fishponds. In the most exposed locations, some small amounts of herbicide residues were detected in runoff, water and sediments of ponds and fish liver. However no traces were found in fish flesh.L’agroécosystème piscicole de la Dombes (Ain) s’appuie sur une gestion intégrée et complémentaire des étangs piscicoles et des parcelles agricoles qui constituent leur bassin versant. La surface agricole du bassin versant et la connectivité des fossés aux étangs déterminent leur degré d’exposition aux pesticides épandus sur les parcelles cultivées. Des situations d’étangs considérés comme peu exposés à très exposés au risque de transfert de pesticides ont fait l’objet d’un suivi. Les pratiques agricoles ont été analysées et les pesticides employés ont été recensés. Le ruissellement, l’eau de l’étang, les sédiments, le foie et la chair de poissons ont été analysés pour rechercher la présence de résidus de substances actives. Les résultats confirment que le risque de transfert de pesticides vers la masse d’eau de l’étang est bien réel, voire important, sur les sites a priori les plus exposés. Toutefois, la contamination du poisson apparaît limitée, aucune molécule n’ayant été trouvée dans la chair des poissons analysés
