Improving formulation and implementation of sustainable strategies is increasingly dependent upon more integrated and participatory decision-making processes. This paper explores the use of qualitative system dynamics tools and a participatory modelling approach to support scoping stages of an integrated sustainability assessment (ISA) process. To facilitate mapping of maritime sustainability issues in Portugal, a series of preparatory interviews allowed eliciting stakeholders' perceptions and their alignment with current public policies. In the subsequent participatory modelling workshop, stakeholders deliberated on maritime problems and constructed causal loop diagrams, identifying feedback structures and voting on leverage points to intervene in the system. Overall results show that the process generated positive outcomes at individual and group levels, stimulating basic systems thinking knowledge and skills. Although further time for model iteration was suggested, the proposed approach promoted learning and a transition toward a shared and more holistic view of maritime problems and its underlying causal interrelationships. This is a promising result for the use of participatory modelling approaches as platforms supporting emerging ISA frameworks. Copyright © 2012 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

Several authors have described the usefulness of participatory system dynamics approaches in environmental decision-making processes, particularly in supporting problem scoping and policy analysis. This paper explores how these approaches may be expanded to provide a coherent, deliberative platform, which structures Integrated Sustainability Assessments (ISA) of policy proposals. The proposed ISA framework forms a five-stage feedback and learning process including scoping, visioning, model building, simulation/assessment and monitoring. We discuss these elements considering a set of best practice principles for participation in environmental assessment and decision making. Subsequently, we lay out a roadmap for implementing and testing the framework. We conclude that participatory modelling has a strong potential for supporting ISA processes. It allows stakeholders to build alternative policies, to reflect on their long-term dynamics, and to gain insights on the interrelationships underlying persistent sustainability problems.
