Dynamics of exploitation systems

Fisheries are exploitation systems of renewable resources with a global dynamic resulting from the interactions between human, social and natural components.
Exploitation dynamics can be studied conjointly with those of exploited resources. These studies are indispensable to the development of fisheries co-management models. They are most particularly important in the case of tropical fisheries, especially artisanal ones, whose fishing units can adapt their activities to the highly variable conditions of access to the diverse components of the exploited ecosystems. In this case, in fact, the impact of fisheries activities is affected by variability ‘decided’ by the fishers. This variability must be well-evaluated and taken into account when evaluating the resource. But most importantly, this variability must also be studied because it depends upon the adaptability of fishers and may hence be a source of viability of exploitation systems.  This leads to the study of halieutic exploitation governance. The term governance indicates that the activity and the rules to which it conforms are the result of the interactions of an important number of involved parties (fishers, consumers, governmental authorities, non-governmental organisations, research organisms ...).
Research in these fields is conducted in an interdisciplinary context, linking social sciences, natural sciences and modeling sciences.
