Annual Report 2018 Council of Agriculture, Executive Yuan technology, we invited scholars from home and abroad and held an “International Workshop on Disaster Prevention and Mitigation Technology for Large-Scale Landlsides.” We also held a joint barrier lake exercise (with the COA’s Soil and Water Conservation Bureau and Forestry Bureau as well as the Water Resources Agency of the Ministry of Economic Affairs participating), in order to build a crisis and risk management mechanism. In 2018, the COA undertook 16 infrastructure projects, completed impact range demarcation in 10 locations, completed an inventory of the protection of 673 structures, conducted evaluations of the appropriateness of land use over 142,000 hectares, and conducted education work and citizen participation involving a total of 4,952 participants. B. Comprehensive mountain management and disaster prevention Based on the concepts of overall planning and management of watersheds, and taking into account the principles of national land restoration—including respect for nature and not resisting the forces of nature—in 2018 the COA implemented disaster prevention and mitigation measures including debris flow disaster prevention, conservation of reservoir watersheds, regional soil and water conservation, construction of green environments, and management of “designated soil and water conservation areas.” The objectives of these measures were to conserve soil and water resources, protect water sources, improve the surrounding scenery, avoid or mitigate disasters, maintain the safety of slopeland, and encourage the rational use of land. The COA also undertook 483 construction projects for conservation management in important reservoir watershed areas and for debris flow disaster prevention, stabilizing about 7.52 million cubic meters of soil. We also completed 15 watershed survey projects. The result of all these policies was to prevent or mitigate damage from debris flow disasters and to conserve soil and water resources. Moreover, the COA improved emergency roads outside of consolidated farmland areas. Taking the roads most in need of improvement as the focus, we conducted 413 construction projects and improved about 246 kilometers of road, on which the COA strengthened soil and water conservation facilities, maintained slope stability, and improved road drainage facilities, in order to maintain the stability of the road bed and smoothness of trafc ow. C. Comprehensive river basin management The Yilan, Changhua, Yunlin, Chianan, and Pingtung Irrigation Associations undertook 26 construction projects for improvement of farmland drainage, improving about 23.77 kilometers of drainage channels and building 21 water management structures, thereby reducing 39
