The priority programme for actions to restore the ecological continuity of the Rhine-Meuse basin Restoration of the ecological continuity of watercourses is necessary to achieve the objectives of good environmental status of watercourses, set out in the European Water Framework Directive and set out in the Master Plans for Water Management (SDAGE). A first programme of actions had been initiated in 2010 by the Ministry responsible for ecology, but difficulties had emerged which delayed its implementation. In order to overcome them, a new action plan for a calm policy to restore the ecological continuity of rivers was adopted in June 2018. One of the actions of this plan is to define, in a consistent manner, shared priorities for interventions in order to effectively pursue the restoration of ecological continuity, in favour of the good status of rivers and the recovery of biodiversity. In the Rhine-Meuse basin, the restoration of ecological continuity is a large-scale project that requires time and means, both financial and human. Indeed, approximately 5.146 km of watercourses, or about 17 % of the total linear, were listed in list 2 in 2012/2013, i.e. a number of works to be brought into compliance within this framework estimated at 16421. As a result of the continuous improvement of knowledge, a total of 13,050 works in the Rhine-Meuse basin of which approximately 4 400 are located on rivers listed in list 2, i.e. 1/3 of the structures in the basin2, were identified in the Flow Barriers (ROE) at the beginning of 2019. It is more than 2.5 times the number of books in List 2 that was raised in 2012 when the classifications were revised, and not all of the works have yet been listed since the ROE feed is progressive. Of these, not all will have to develop or modify, but action remains necessary for a large number of them. Finally, there are large disparities between the territories in the number of books to be processed, with the departments of Vosges, Bas-Rhin and Haut-Rhin concentrating the majority of them. In view of this context, it was therefore decided to draw up, at the level of the Rhine-Meuse basin, a list of priority works requiring work (equipment, fitting-out, erasure, etc.). This prioritisation strategy has to first identify priority areas (priority watercourses for the protection of amphihalin migratory fish, biological reservoirs identified in the SDAGE, etc.) and then, on these watercourses or parts of watercourses designated as priorities, to identify the most impacting works (works influencing a significant linear, blocking access to spawning grounds, etc.). In 2018/2019, the departmental directorates of the territories, the French Agency for Biodiversity, the Agence de l’eau Rhin-Meuse and the Regional Directorate for Environment, Planning and Housing worked together to identify the most relevant actions in terms of ecological gain or feasibility. These departmental lists of priority works have been validated by MISEN (Missions Inter-Services for Water and Nature) after consultation with stakeholders at departmental level. These lists, compiled at the basin level, formed the programme for prioritising interventions in the restoration of the ecological continuity of the rivers listed in list 2 in the Rhine-Meuse basin. In order to finalise the consultation with all water users, this programme was presented to the basin bodies (planning committee, basin committee) which gave a favourable opinion. The programme was validated on 16 January 2020 by the Rhine-Meuse Basin Technical Secretariat, mandated by the Basin Committee. In total, the Rhin-Meuse prioritisation programme has 514 prioritised works over the period 2019-2027: — 200 works in a 2019-2021 list to be implemented under the Territorialised Operational Action Plans (TAPs) 2019-2021; — 314 works in a 2022-2027 list, the implementation of which will be backed by the SDAGE Programme of Measures for the period 2022-2027. Legally, the obligation to ensure the movement of fish and the adequate transport of sediments over all rivers listed in List 2 is maintained (Article L.214-17 of the Environmental Code). The prioritisation programme tends to avoid overruns or to reduce actual delays on the basis of a principle of reality. It must make it possible to move forward more effectively.
