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 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...

Using a new framework combining vulnerability and exclusion as two central dimensions of poverty, this article revisits some of the long-standing beliefs about poverty in small-scale fisheries. We argue that the issue of poverty in fish-dependent communities cannot be reduced to a simple...

The ecosystem approach for fisheries advocates an integrated management of marine resources that promotes both conservation and sustainable use in an equitable way. Co-viability is proposed here as a relevant modelling framework to deal with the analysis and exploration of scenarios in line with...

Resilience has become prominent in academia where it is used as a central framework in disciplines such as ecology, climate change adaptation or urban planning. Policy makers and international development agencies also increasingly refer to it. The objective of this paper is to assess the...

Today fish is the most traded food commodity in the World. This situation is not without generating potential issues. On the one hand, fish trade is said to support economic growth processes in developing countries by providing an important source of cash revenue. On the other hand, fish trade...

The intensification of agricultural productivity through technological innovation has often been reported to induce considerable social and economic transformation in the rural communities where those innovations are introduced. This paper investigates those changes in the case of acadja, a...

In this study we analyse the role of the storageregulation in a fishery's production process when theresource exploited and the market to which theproduction is exported are characterized by seasonaldephased oscillations. For this purpose we built up adynamic model drawn from the French Guyana...
