5.6.9 Parc Naturel Régional du Golfe du Morbihan: Detailed description of the scenarios approach

Step 1

Thanks to the Ecosystem Services Assessment of seagrass beds of the Golfe du Morbihan, four scenarios (e.g. management strategies) have been identified.

Step 2

These four scenarios were presented the September, 18th 2014 to 20 participants during a “scenarios workshop”. Through an open discussion based on maps illus-trating the four scenarios, the stakeholders have identified for each of them their strengths, weaknesses, opportunities and threats through an adapted “SWOT” analysis ( strengths, weaknesses, opportunities and threats) .

Step 3

The participants were then asked if they felt the scenarios were desirable and feasible. The method of the “Abaque de Régnier” was used to collect the quotes and identify the items on which there was consensus or not between the participants.

Using an Excel algorithm, the results were then analysed to identify if there was consensus between the participants.

• One of the major conclusions was that the scenario 4 was the only one on which there was a consensus saying that it was desirable.
• However, with regards to the feasibility of scenarios, the scenario 4 was also the only one with no consensus between the participants as to whether was feasible or not.
• The participants seemed to agree the fact that a new management of seagrass beds at a finer scale is needed but that this seemed also complex to implement...

Step 4

The next step during the “scenarios workshop” was to propose, in the light of the advantages and disadvantages of each scenario identified beforehand, possible management options that could be implemented to improve the seagrass beds of the Golfe du Morbihan. For each proposition considered by the participants, it was asked what the time horizon of implementing the management measure, the partnership required and the process of the implementation.

A total of twenty management measures were identified by the participants during the workshop.
