| 内容記述 | Paddy field land consolidation projects, which started in 1963 in Japan, have made significant contributions, such as promoting rural areas, solving postwar food shortages, and improving agricultural productivity. In the last several decades, however, there has been a decline in wildlife species adapted to the secondary natural areas inherent in rural landscapes. This decline has resulted from changes in farming methods and the use of large quantities of agricultural chemicals, mechanization of farm work using tractors and combine harvesters, and paddy field land consolidation projects undertaken to improve agricultural output and productivity. In response to this decline, a 2001 amendment of the Land Improvement Act provided that the impact on the environment should be taken into consideration when undertaking these projects. From the viewpoint of maintaining biodiversity, however, the measures undertaken so far have been inadequate. In this thesis, I describe achievements made in mitigation systems in some public work projects in Japan and abroad and examine their applicability to paddy field land consolidation projects. Mitigation, which was first emphasized in American environmental assessments conducted in 1969, refers to acts that counteract the negative impact on ecosystems caused by development projects, including (1) avoidance, (2) minimization, and (3) compensation, listed in the order of priority. The aim of this basic research is to investigate how various mitigation measures during paddy field land consolidation would affect dragonflies, which serve as representatives of wildlife in rural areas. For example, acts falling under “avoidance” would involve conserving particularly important habitats (hot spots) when consolidating land. “Minimization” would involve carrying out consolidation in stages and maintaining habitat networks while taking into account metapopulations. As for “compensation” acts, I propose using fallow fields and other sites to establish biotopes, build thriving habitat networks, and implement ecological farming practices. In order to balance the conservation of dragonflies that inhabit stagnant water with farming, I propose an improved version of inundating paddy fields in winter based on chemical-free, zero-tillage cultivation, which combines existing farming techniques with knowledge of the life cycle of dragonflies, the drought resistance of larvae, and other important species traits. In this research, I studied the impact of paddy field land consolidation projects on the habitat quality of dragonflies and proposed countermeasures based on field measurements of drought resistance of larvae and the potential traveling range of adult dragonflies. These basic data can be used to devise sound mitigation practices and improve the quality of conservation measures for dragonflies. | |||||||||||
