AbstractThe productivity of marine resources depends on the dynamics of target species, but also on non-target organisms, interactions between species, and impacts of environmental conditions and human pressures. All these relevant elements have to be considered to assess ecosystem dynamics and manage marine resources sensibly. With the exponen-tial increase of computation power and data availability, the scientific community has made substantial progress in the identification and quantification of multiple environmental and human pressures that drive marine ecosystems. There has also been a proliferation in novel techniques to integrate and assimilate data, and in ecosystem modelling capabili-ties that take into account uncertainties in data and processes. Here I provide an overview of several dynamic tools available to model ecosystem dynamics and cumulative effects and their advantages and limitations. Afterwards I reflect on the challenges the scientific community is currently facing. I finish by discussing how novel approaches can address these challenges, with emphasis on using the Ecopath with Ecosim modelling framework
