요약	Deliberative monetary valuation is a hybrid method that combines the deliberative processes of political theory with the monetary metric of environmental economics, eliciting willingness to pay for environmental change through structured group discussion rather than isolated individual survey responses. In Clive Spash's 2007 analysis, the approach responds to a central criticism of conventional stated-preference methods — that they assume people arrive with well-formed preferences and treat them as private consumers — by giving participants information, time, and the company of others with whom to reason before expressing a value. Deliberation can produce individual willingness-to-pay figures formed through discussion, or genuinely social values agreed by the group acting as citizens. Spash stresses that the resulting numbers can rest on very different ethical bases, from market exchange to fair prices to expressive or arbitrated social judgments, which complicates their interpretation as standard welfare measures.	Participatory scenario planning is a structured, multi-stakeholder method for exploring how a social-ecological system might unfold under irreducible uncertainty, rather than predicting a single most-likely future. Drawing on the scenario tradition formalized for conservation by Peterson, Cumming and Carpenter in 2003, it brings together researchers, managers, and affected communities to identify the forces driving change, isolate the critical uncertainties that matter most, and build a small set of contrasting yet plausible and internally consistent narratives. Candidate policies are then stress-tested across these alternative futures to find strategies that remain acceptable no matter which future arrives. Because the scenarios are co-produced, the method also builds shared understanding and social capital among participants who may begin with divergent interests.
