This paper summarises the evolution of UNESCO's Ecohydrology programme during the last 25 years within the different phases of the Intergovernmental Hydrological Programme (IHP) but focuses particularly on its implementation during IHP-VIII phase, from 2014 to 2021. The Ecohydrology programme is steered by a Scientific Advisory Committee composed of internationally well-known scientists from all over the world, which promote strategic directions and new scientific dimensions, design activities to be undertaken, as well as program execution, and communication of scientific advances and lessons learnt within the programme. It also especially takes advantage of the considerable and essential contribution of members of the UNESCO Water Family, in particular from water Centres and Chairs dedicated to ecohydrology. The paper also describes the major milestones obtained during the eight years of implementation, going through the major activities organized in the framework of the dissemination of the concept within different scientific networks, international conferences, trainings, workshop, publications as well as major innovative trends the programme accounted for. The COVID-19 outbreak greatly impacted the execution of the programme during 2020 and 2021 as major international events and activities were cancelled or postponed. One of the programme's responses was the organization of the Ecohydrology Online Open Courses (EH OOC) on a dedicated platform.

本文总结了过去 25 年来教科文组织生态水文计划在政府间水文计划 (IHP) 不同阶段的演变，但特别关注其在 2014 年至 2021 年的 IHP-VIII 阶段的实施情况。由来自世界各地的国际知名科学家组成的科学咨询委员会，促进战略方向和新的科学维度、将要开展的设计活动以及计划执行，以及在计划内交流科学进步和经验教训。它还特别利用了联合国教科文组织水家族成员的重要贡献，特别是来自致力于生态水文学的水中心和教席。该文件还描述了在八年实施过程中取得的主要里程碑，回顾了在不同科学网络、国际会议、培训、研讨会、出版物以及主要创新趋势的概念传播框架内组织的主要活动。计入的程序。由于重大国际事件和活动被取消或推迟，COVID-19 的爆发极大地影响了 2020 年和 2021 年计划的执行。该计划的回应之一是在专用平台上组织生态水文学在线开放课程 (EH OOC)。国际会议、培训、讲习班、出版物以及该计划考虑的主要创新趋势。由于重大国际事件和活动被取消或推迟，COVID-19 的爆发极大地影响了 2020 年和 2021 年计划的执行。该计划的回应之一是在专用平台上组织生态水文学在线开放课程 (EH OOC)。国际会议、培训、讲习班、出版物以及该计划考虑的主要创新趋势。由于重大国际事件和活动被取消或推迟，COVID-19 的爆发极大地影响了 2020 年和 2021 年计划的执行。该计划的回应之一是在专用平台上组织生态水文学在线开放课程 (EH OOC)。
