Abstract:This paper is about PLEC,but also about small farmers and biodiversity . Until a very few years ago, all agriculture was supposed to be the enemy of biodiversity . Now it is better understood that some areas managed by small farmers contain almost as much biodiversity as the wild. This diversity, (Wood and Lenne 2000).Even in regard to the wild itself,ecological thinking has now swung away from the old view that the richest biodiversity occurs in ecosystems that have had a long period of undisturbed evolution toward a"cli max"state. Since the late 1970s it has been forcefully argued that disturbances may be essential to the creation and maintenance of plant and animal diversity (eg. Zimmerer and young 1998).
