Abstract

[fre] II est logique d'étudier les relations entre écosystèmes et agriculture. En effet, l'agriculture peut être regardée comme un type particulier d'écosystèmes du fait que l'homme est intervenu pour les domestiques, pour les transformer profondément et même pour en créer d'entièrement artificiels, que l'on désigne généralement sous le vocable d'agro-systèmes. La domestication des écosystèmes naturels a consisté à les simplifier de manière à concentrer la productivité de l'écosystème sur une seule plante choisie, et à le maintenir à un niveau élevé et plus ou moins constant. En contrepartie, la stabilité des agro-écosystèmes est beaucoup moins grande, ce qui explique leur fragilité. Celle-ci se marque par une moindre résistance aux accidents ou perturbations extérieures et aussi par la nécessité de prendre continuellement des mesures compensatoires afin d'atteindre la stabilité, caractéristique dominante des écosystèmes. [eng] Relationships between ecosystems and farming - It is logical to study the relationships between ecosystems and farming, for farming can be regarded as a particular type of ecosystem since man has stepped in to domesticate it, to change them profoundly and even to create totally artificial ones — agro- systems. This domestication of natural ecosystems has consisted in simplifying them so as to concentrate the productivity of the ecosystem on one chosen plant and maintaining it at a more or less unvarying high level. On the other hand the stability of agro-ecosystems is not as gerat which explains their stability which is marked by less resistance to external accidents or perturbations and also by the need continually to take compensatory measures in order to attain stability, the chief characteristic of ecosystems.
