Collective Innovation Sustainable Management Unit 2: Building Agricultural Models and disaster-prevention or disaster- mitigation functions of irrigation; and (x) completed improvement of 353 kilometers of emergency irrigation canals in “consolidated farmland” areas, thereby ensuring the smoothness of flow in irrigation canals in these areas. All these measures improved the operational environment for farming as well as the quality of life in rural areas. (3) Maintaining agricultural environmental resources and safety A. Construction of a system for “Large- scale Landslide Disaster Prevention and Mitigation under Climate Change” In 2018, the COA did the tasks of “strengthening response capabilities for large-scale landslides,” “constructing a smart disaster prevention system for large- scale debris flow disasters,” “increasing the effectiveness of management of large- scale debris flow disasters,” and “refining resource conservation in large-scale debris ow disasters.” The COA also did multi-scale monitoring of, and study of, large-scale landslides, and created a mechanism for monitoring their occurrence by using (i) interpretation of the images from satellites, (ii) surface displacement observation and monitoring, and (iii) on-site monitoring. We also delineated the impact range of large-scale landslides, and did a census of the persons to be protected within these impact ranges. Moreover, the COA set large-scale landslide warning thresholds and management thresholds based on the monitoring data, for reference in future evacuations from high- risk disaster areas. Further, in order to stay abreast of international large-scale landslide research and disaster mitigation The “2018 International Workshop on Disaster Prevention and Mitigation Technology for Large-scale Landslides.” 38
