endangered biodiversity in Europe. As explained earlier, the regulation of the water
level of the Arzal reservoir may induce flooding in the upper wetlands during the
dry season. The Natura 2000 committee represents hunters, naturalists and some
farmers with concerns about the periodicity of the flooding of those natural areas.
The committee was created at the same period as the site network and contributes
actively to the SAGE Vilaine.
6.4 Assessment of Drought Governance Qualities
In this section, we present our findings regarding the observations on the four
qualities of the governance assessment tool, namely, extent, coherence, flexibility
and intensity, assessed on the five governance dimensions of the matrix that forms
the framework of the GAT (Bressers et al. 2013a, b, c).
To the greatest extent possible, this analysis distinguishes between (a) water
management and governance as such and (b) governance related to drought
adaptation. These elements do not have the same aims. Water management is part
of an integrated system that is implemented in almost all decision-making bodies.
Adaptation to drought is mainly restricted to water level regulation and the management of water crises during drought.
6.4.1 Extent: Large for Water Management and Limited
for Drought Management
The levels and scales dimension has a truly supportive basis in the water management of the Vilaine catchment. The administrative management of the entire
Vilaine catchment has a wider extension, with scales ranging from the European
level at the top through the national, regional, departmental, and intercommunal
levels and all the way down to the communal level. As for the SAGE Vilaine
(Sect. 6.2.2) and the management of the Arzal dam and its reservoir by IAV, the
involvement of representatives of each level is not the same: three departments
(Morbihan, Ille-et-Vilaine, Loire-Atlantique, Fig. 6.2) are more involved in the
decision-making process than the others. This can be explained by the fact that the
other three departments within the Vilaine catchment (Côtes-d’Armor, Mayenne,
Maine-et-Loire, Fig. 6.2) are less affected by the management of the Arzal dam.
However, the whole catchment of the Vilaine is involved in the local water commission (LWC), representing six departments within two regions. Drought management relies on the same organization as that of water management, and, for that
reason, the levels and scales that are potentially included are as large as the ones
involving water management. However, water crisis management is situated at the
national level.
