| Research Abstract |
We revealed the factors driving the biodiversity loss in the irrigation ponds of the southern Hyogo Prefecture. We also suggested methods for efficient conservation and management from both the ecological and environmental-economic points of view. The main causes of the biodiversity loss were eutrophication, concrete revetment, and invasion by bluegill, thus it is crucial to control these factors. In addition, the presence of the people who could communicate about conservation and its significance is important, and local people tended to cooperate according to the situation of the others.
