Coût d’opportunité versus coût du maintien des potentialités écologiques : deux indicateurs économiques pour mesurer les coûts de l’érosion de la biodiversité ArchiMer
Levrel, Harold; Hay, Julien; Bas, Adeline; Gastineau, Pascal; Pioch, Sylvain.
The cost of ecosystem services degradation is a major topic as underlined by the TEEB program (The Economics of Ecosystems and Biodiversity), which proposed an assessment of the costs of policy inaction in the field of biodiversity conservation. In the same vein, the report of the French Centre for Strategic Analysis on the Economic Approach to Biodiversity and Ecosystem Services turns its attention to the value of ecosystem services, suggesting some elements that could help measure the cost of biodiversity degradation. There is however some confusion regarding the notion of cost. Thus, in the case of TEEB the proposed cost assessment translates into monetary terms the loss of potential profits from ecological services. Yet, another way of assessing these...

La construction navale optimisée. Le choix de matériaux d'âme et la fabrication sont étroitement liés ArchiMer
Gellhorn (von), E; Mittelmann, G.
Sandwich panels with a facing of laminated fibre reinforced plastics are now established boatbuilding materials. In the last few years they have begun to replace the traditional metal and wood in ship and marine construction. Today's materials are usually selected on the basis of minimum cost and simplicity of construction. This is often contrary to the demands of the owner who wants an inexpensive, safe, easy-care and long-lasting ship. The requirements of boatbuilder and operator can easily be satisfied if the combination of the best choice of materials and new, rationalized construction methods are considered. Taking the construction of the boat "Sandwich" as an example we will demonstrate the increased importance of the tough rigid linear PVC foam core...

La pêche artisanale des années quatre-vingt en France ArchiMer
Catanzano, Joseph; Lantz, Frederic; Vernier, C; Allard, M.o.
The artisanal fisheries industry has experienced a major development over the 80's: technology has improved and ship building costs have increased. The firms' economic behaviour and financial performances have shown that the marginal profitability of capital is lower for large units than for small units, the latter being used by coastal fisheries. Overall, conclusions on the financial situation of the industry must be qualified. Public intervention has materialized through (1) an increasing amount of state aids supporting modernization investment (Brittany being the most supported region), (2) more political and financial involvement of regions as a result of more administrative and decision making responsibilities being devolved to them, (3) the...
