QUICKScan is a tool to facilitate the decision process in participatory settings. By including stakeholder knowledge and preferences and the ability to calculate impacts in-situ, QUICKScan combines tacit expert knowledge with available spatially-explicit monitoring and statistical and uses visualisation and interpretation tools to support the exploration of options allowing and facilitating discussion of alternatives, analysing their consequences, and determining trade-offs and synergies. Typically multiple iterations of a modelling exercise are run during a workshop. The results of each iteration feed into the discussion among stakeholders and policy-makers creating input for the next iteration.
