Biodiversity and bioproductivity for sustainable agriculture

本研究的主要目的是阐明在全球环境变化导致不稳定性增加的情况下，可持续农业生产系统的方法。作为第一步，瑞士高地作物种植小组和东京大学水稻生产系统小组这两个小组就世界不同农业生态系统的可持续问题进行了合作研究审查。在此基础上，确定了本研究的研究目标为两个方面，一是高地作物可持续栽培的合作研究，二是水稻生产系统的可持续性问题。前一个小组发现了关于精确耕作和旱地作物生物多样性维持的各种宝贵信息。后者指出了稻田土地利用方式和能量消耗过程对稻田农业稳产的重要性。该研究项目的这些发现对于在世界上建立可持续的作物生产系统是不可或缺的。

Major objective of this research was to elucidate the methods for sustainable agricultural production system under increased instability due to the change of global environment. Collaborative research review-,on sustainable issues in different agricultural ecosystems in the world was conducted by the two groups, the Swiss group working on upland crop cultivation and Tokyo University group working on paddy production system as the first step. Based on this review, the target of research for this research was fixed at two aspects, one is the cooperative research, on sustainable upland crop cultivation and the other is the sustainability issue in paddy production systems. The former group found out various valuable informations on precision farming and biodiversity maintenance for upland cropping. The latter group pointed out the importance of the land use method of paddy and energy consuming process for stabilized production in paddy farming. These findings in this research project are indispensable for the establishment of sustainable crop production systems in the world.
