S3-EUROHAB has a dedicated work stream that aims to analyse and, where possible, qualify and quantify the social and economic impacts of HABs directly on the shellfisheries, aquaculture, tourism sectors and wider local economies in four case study sites in the French-English Channel region. It will also assess the cost effectiveness of the web-based HAB alert system and how different sectors respond to the information contained within it.
HAB events are relatively rare on the English side of the Channel and for much of the shellfisheries sector they currently have little impact. The aquaculture sector, due to its static nature, is more vulnerable to HABs and does suffer economic costs as a consequence. Evidence indicates that tourism-related businesses are also affected (Willis et al. 2018). On the French side of the Channel, HABs are a more significant issue. Parts of the Bay of Seine are frequently closed due to the presence of HABs, while the Bay of Brest has remained closed for several years.
Through collaboration between Plymouth Marine Laboratory, Université de Bretagne Occidentale and IFREMER and focusing in the UK on the Cornish coast from the Lizard to Rame head and the South Devon coast and in France on the Bay of Brest and Bay of Seine, a series of activities will be undertaken including:
To date activities have included the preparation of a stakeholder inventory, identifying the multitude of organisations with interests in HABs; stakeholder workshops in the UK and France to discuss perceptions and impacts of HABs; and definition of the existing HAB monitoring system. A summary of these findings and a short report from the stakeholder workshops can be found here.
On-going activities are focusing on the collation of historic information on HABs and characterising the structure of the shellfish and aquaculture sectors within the wider economic structure of the case study sites. This is being accompanied by further interviews and workshops to gather stakeholder perceptions of HABs and their social and economic impacts.
