Conservation of marine habitats under multiple human uses. Methods, objectives and constraints to optimize a Marine Protected Areas network in the eastern English Channel ArchiMer
Delavenne, Juliette.
The eastern English Channel is a significant economic area that supports a number of human-based activities, such as tourism and recreational activities, international ports and shipping, and the extraction of both living and mineral resources. In addition, the region supports a number of important marine biological features and large habitat diversity. Marine Protected Areas (MPAs) are increasingly used as a management tool to foster a sustainable exploitation of marine resources in an ecosystem based management framework. All European countries have a legal obligation to develop MPA networks in their national waters. However, there has to date been only limited attempts to coordinate the design and positioning of such networks at an international level...

Evaluating conservation and fisheries management strategies by linking spatial prioritization software and ecosystem and fisheries modelling tools ArchiMer
Metcalfe, Kristian; Vaz, Sandrine; Engelhard, Georg H.; Villanueva, Ching-maria; Smith, Robert J.; Mackinson, Steven.
Well-designed marine protected area (MPA) networks can deliver a range of ecological, economic and social benefits, and so a great deal of research has focused on developing spatial conservation prioritization tools to help identify important areas. However, whilst these software tools are designed to identify MPA networks that both represent biodiversity and minimize impacts on stakeholders, they do not consider complex ecological processes. Thus, it is difficult to determine the impacts that proposed MPAs could have on marine ecosystem health, fisheries and fisheries sustainability. Using the eastern English Channel as a case study, this paper explores an approach to address these issues by identifying a series of MPA networks using the Marxan and Marxan...

Systematic conservation planning in the eastern English Channel: comparing the Marxan and Zonation decision-support tools ArchiMer
Delavenne, Juliette; Metcalfe, Kristian; Smith, Robert J.; Vaz, Sandrine; Martin, Corinne S.; Dupuis, Ludovic; Coppin, Franck; Carpentier, Andre.
The systematic conservation approach is now commonly used for the design of efficient marine protected area (MPA) networks. Identifying these priority areas often involves using specific conservation-planning software. Several of these software programmes have been developed in recent years, each of which differs in the underlying algorithms used. Here, we investigate whether the choice of software influences the location of priority areas by comparing outputs from Marxan and Zonation, two widely used conservation-planning, decision-support tools. Using biological and socio-economic data from the eastern English Channel, we compared their outputs and showed that the two software packages identified similar sets of priority areas, even though the relatively...
