This project aims to collect data from stakeholders in the Orb River Basin to diagnose and understand the basin's issues and develop a comprehensive management plan. Semi-closed questionnaires and participative recording will be used to gather input from stakeholders. The data collection will include information on rainfall, discharges, land use, population, and administrative data. The spatial representation of the basin and stakeholder perceptions and relations will also be analyzed.

Collecting first input from stakeholders • Goal : diagnosis and comprehension of the basin • Principle : semi-closed questionnaires, recording, participative • Request to interviewee for drawing her spatial representation • Global basin mapping • with various topics (relief, river, towns, roads) • only basin boundaries • 3 sub-catchments (upstream, medium valley, downstream) • And functional stake analysis schema Cause Problem Consequence
Interviewed stakeholders 18 stakeholders (1st ring) 3 elected representatives 3 NGOs 6 Socio-professionnals 3 technicians 3 general referees
Interviews debriefing Name : Date : Structure : Role : Address : Telephone number : Interview debriefing Description of the river basin : Stakes, mains issues : Actions on the basin : Evolution in the past: Plans for the future : Perception of stakeholders positions & relations : Difficulties and achievements : Changes in stakeholders structure :
Synthesis (in progress) • Schema by stake • perception of the organisation of the water management in the Orb scale • perception of the spatial segmentation • typology of stakeholders • validation of the main stakes

The stakeholders spatial segmentation • What are the main issues raised by the management of • the water in the river basin? • Can you draw them? • Various segmentations related to : • the most important issues : floods & water quality mainly • the kind of stakeholder (local or global concerns), of its activities • the physical environment • Segmentation example :
Upstream sector : rural and limited effects Example of segmentation SMVO Floods dam d ’Avene Avene Mare Lac of Laouzas Bedarieux Lamalou Intermediary sector : flood expansion field, dam Thes Bains aqueduct of Montahut Olargues Orb Jaur Saint Pons downstream sector : the most endangered : concentrated population and flat, delta Cessenon Vernazobre Lirou Important flood risks Beziers Locals risks of flood Canal du Midi Potentials areas of storage Valras-plage Mediterranee
Notions of « stakeholders typology » • Typology by stake : • floods : • Interested : • all the elected representative (responsibility population protection), • The associations (environment protect ) • Administrations and professionals working on the subject : • improving the flood forecasting system • regulated area • Reasons : social demand and human stake • regulation, protection installations, crisis management
stakeholders & relations : • SMVO : facilitates concertation and coordination • few problems of concertation on the Orb • River contract : positive, allows territory improvement • Conseil Général (Dept author.) = the main stakeholder of the river contract • Population : not enough embedded in the course of action • Lack of human means, of information dissemination • For the future… : • A need of contracting authority : future part of the SMVO ? • Rivers upkeep problems: should be made by an organism independent of the municipalities • Need to combine solutions Municipalities comments
Contracting authority : the SMVO Asked by the elected representative and the administration (project progress) The studies Socio-professionnals : lack of access, disponibility, distance and references The communication : Facilitated by the river contract, but the small structures are not heard Evolutions : SAGE : envisaged by the elected representative (would permit the amelioration of actions) administration position ?
Inondation stake • Interventions • Modification of Avene management (hazard) • Control OS agriculture + specifical conversion (hazard) • Control and use of gravels (hazard) • Maintaining ripisylve reeds (hazard) • Control OS urban, tourism, and agriculture (vulnerability) • dams, conversion, Grande Maïre (hazard)
Stake inondation • Model vs prospective scenarios • Cost/ advantage (integrated) of actions on hazard via OS agricole & Gravels • Control and modify urban POS and tourism • protection installation downstream • Negociation • Farmers inundability & Gravels vs other
Communicate the expert flood model Floods forecasting ? Vegetal engineering ? support and integration ? Water and river culture Upstream / downstream concertation
Participatory follow-up • Done : 35-40 h of interviews, discussion with main contracting stakeholder (SMVO) • Planned : • Debriefing (anonymous) of basin diagnosis with stakeholders + presentation of the objectives of the future modelling & participatory activity • Discussed : • Population surveys ? • Focus groups or role playing approaches ?
Discussed presently : • choosing between focuses • agricultural changes and their effects on floods, irrigation and water quality • effect and dynamics of tourism in relation with water and local economy
