L' adoption d'innovations culturals dans les villages du Petit triangle (Israel).

The development of agriculture in the Arab villages of the Little Triangle, along the Sharon plain, was marked during the 60s and 70s by the adoption of innovations - among others, crops under plastic and glass cover - and the introduction of many new species and varieties of vegetables. The article shows that Arab farmers are very often open to innovations: having got free technical assistance, they followed the patterns of innovations of Jewish agriculture. The expansion of new cultures followed, both chronologically and spatialy, the usual patterns of diffusion, but only in a limited area. Human factors such as distribution of water, preexistant cultures, but also physical factors, such as pedology, caused this restriction. -English summary
