Abstract
  • The World Summit on Sustainable Development (Johannesburg, 2002) encouraged the application of the ecosystem approach by 2010. We propose a framework that deals jointly with i) ecosystem dynamics, ii) conflicting issues of production and preservation and iii) robustness with respect to dynamics uncertainties. More specifically, we define robust viability kernels as initial species biomasses such at least one appropriate harvesting strategy guarantees minimal production and preservation levels for all times, whatever the uncertainties. We apply our approach to the anchovy--hake couple in the Peruvian upwelling ecosystem. We comment on the management implications of comparing robust viability kernels with and without uncertainties.
