Terrestrial and marine biodiversity provides the basis for both ecosystems functioning and numerous commodities or services that underpin human well-being. From several decades, alarming trends have been reported worldwide for both biodiversity and ecosystem services. Therefore the sustainable...

Academia and management agencies show a growing interest for ecosystem-based fishery management (EBFM). However, the way to operationalize this approach remains challenging. The present paper illustrates how the concepts of stochastic co-viability, which accounts for dynamic complexities,...

This paper deals with the sustainable management of a renewable resource based on individual and transferable quotas (ITQs) when agents differ in terms of harvesting costs or catch capability. In a dynamic bio-economic model, we determine the feasibility conditions under which a fishery manager...

This paper presents an application of stochastic viability approach in a tropical small scale fishery context, offering a theoretical and empirical model of ecosystem-based fishery management. A multi-species and multi-fleet bio-economic model integrating Lotka-Volterra trophic dynamics as well...

Balancing bio-economic risks and high profit expectations is often a major concern in fisheries management. We examine this trade-off in the context of the Australian Northern Prawn Fishery (NPF). The fishery derives its revenue from different prawn species with different dynamics and...

This article determines the conditions under which theSouthern countries should act together, or separately, whilenegotiating with the North about climate change policy andabout the conditions for future Southern engagement. The papermodels the international negotiations with complete and...

This paper deals with the sustainable management of a renewable resource based on individual and transferable quotas (ITQs). The aim of that paper is to determine the conditions under which a regulating agency can achieve both ecological and economic objectives when agents are heterogenous and...

A system subject to corrective and preventive maintenance actions is considered. Corrective Maintenance (CM) is done at unpredictable random times and is assumed to have As Bad As Old (ABAO) effects. Preventive Maintenance (PM) is supposed to be done at deterministic predetermined times and to...

This paper deals with the contribution value of biodiversity to ecosystem performances under a viability approach. Two contrasted cases are considered. First, a no-exploitation situation where the ecosystem performances are measured through the capacity of species richness to maintain the...
