Indirect stakeholder involvement covers contributions to the framing of the modelling endeavour, model evaluation and model use. Various sub-forms of indirect involvement are conceivable. Stakeholders can be invited to review the design of the model, a process corresponding

to the extended peer review concept. Stakeholders can also be asked to provide input to model use in form of scenarios (in terms of policy or management options), or in form of critical reflections over the causal logic of these inputs. The appropriate stage(s) for stakeholder input in the modelling process need to be identified at an early stage [21]. To stimulate the feeling of ownership and to increase legitimacy and effectiveness, KU-60019 stakeholders should be involved from the very first, the problem-framing, step. Drakeford et al. [25] and Dreyer et al. [18] carried out a literature review of participatory modelling in natural resource governance. The synopsis of the results of this review offers, in short form, practical implementation assistance to such participatory

exercises [29]. Drawing on main analytical distinctions provided by the literature screened, it sets out different purposes envisaged, specifies different modelling phases at which stakeholders could be involved [21], and points out how the timing of participation is linked to the degree to which stakeholders can influence model-based

knowledge ABT-199 clinical trial output. One basic design principle of participatory processes is clarity of Reverse transcriptase purpose for all participants [14, p. 228]. A participatory process should be designed with a clear purpose in mind of both, modelling and deliberation, and sharing this understanding with all participants. Dreyer and Renn [29] highlight four purposes of participatory modelling in the context of natural resource governance [20], [22], [30], [31] and [32]: (A) Collective learning for consensus-building and/or conflict reduction; (B) knowledge incorporation and quality control for better management decisions; (C) higher levels of legitimacy of and compliance with management decisions; (D) advancing scientific understanding of potential and implementation requirements of participatory modelling. In fisheries, so far stakeholders have been involved in modelling activities only sporadically, mainly through research projects (e.g., EFIMAS, PRONE, GAP1), hence, with a focus on purpose D. The JAKFISH literature review found only few cases in Europe where participatory modelling aimed at directly supporting actual decision-making processes [33] and [34]. The characterization of uncertainties is an important element of participatory modelling approaches. Traditional characterizations based on quantifiable uncertainties [35] tend to ignore uncertainties that are not amenable to quantitative analyses.
