institutions
Institutions in this case study are difficult to describe according
to this classification due to the small size under study and to
the specific way of management which actually raised our interest
for this area.
Institutions
may be described according to their scale of action, to their level
of organisation and to their rate of private/public character
Several
institutions with a scope larger than SMVO are acting in the area
either locally and/or through global decisions with local consequences
:
-
public : European Commission, French agriculture, environment,
equipment and industry departments directly and through their
local representative, regional and departmental administration
and water bodies á
- semi-public
: EDF, BRL, Chambers (industry and agriculture), CSP
-
private : fresh water companies, environmentalist lobbies, farmers
unions, sports associations
Local
institutions have also a strong influence in the dynamic of the
system : á public : SMVO (+ informative board), municipalities
- semi-public
: parc rŽgional du Haut Languedoc
- private
: local environmentalist lobbies, local sections of farmers Unions,
irrigators associations, riverside residents association, fishers
association, professional of tourism, sports associations
process
analysis for each issue
What are the
major questions that you would like to address with the model at
the current stage of knowledge about the region and stakeholder
interests?
- to make
available a discussion support system for negotiation among stakeholders,
objective (in the sense in the hypotheses are explained) and synthetic
(for main stakeholder SMVO and us)
- to represent
the dynamic of a specific dialogue mode for water management in
order to analyse it (for us) and to give insight on the whole
process (for main stakeholder, SMVO)
How do you intend
to organize the participatory process with specific reference to
problem specification?
- analysis
of former studies
- interviews
- collective
restitution of results in the frame of the consultative body accompanying
the river contract
What are the
major uncertainties you are currently aware of and how do you intend
to deal with these uncertainties?
The major uncertainty
is the evolution of activities and population in this area. Middle
term uncertainties are the evolution of the regulation with the
new water law of 2001 and the Rhone/Barcelone aqueduct impacts if
it will be carried out.
details
of regional case studies
- Available
datasets / short characterizations
- available
in Cemagref : rains and discharges (daily) ; BD topo & carto,
Corine Land cover, RGA, SIREN, INSEE
- not
yet available in Cemagref but possible to acquire if necessary
: data relative to activities in the area
- Historical
account about the major developments over the past decades that
are of relevance to embed the case study in a larger picture (changes
in regulatory framework, public perception, financial situation,
environmental situation)
- evolution
of population and activities
- evolution
of regulation of water management
La perception
a du aussi sacrement Žvoluer, notamment sut l'amont du bassin
o dans un contexte minier (vallŽe de la mare + rŽgion de BŽdarieux),
l'eau permet d'Žvacuer les dŽchets.
