Envisioning sustainability: Recent progress in the use of participatory backcasting approaches for sustainability research

This paper describes recent progress in the utilization of participatory scenario-based backcasting approaches to sustainability research that blend quantitative and qualitative analyses in order to explore alternative climate change futures, as undertaken in a range of academic, government, and private sector projects in the Lower Mainland of British Columbia, Canada. These projects reveal that buy-in to policy proposals may be enhanced by participation, but there is a risk of participants being overwhelmed by the complexity of the choices they are being asked to make. Furthermore, tools are grounded in a process, which must itself be the explicit focus of attention in designing successful backcasting projects and combining participatory backcasting techniques with more interactive processes that can enhance our ability to explore highly complex and uncertain, value-laden issues. These approaches can be used to drive action and support decision-making, but for a truly consultative and consensus-oriented process to occur, it is important that a broad sample of the community be engaged in the discussion that are equipped with technical knowledge or understanding of the goals of the process in order to participate in an equitable and effective fashion.

Research Highlights
► Second order backcasting is explicitly normative and participant-led.
► It facilitates social learning about consequences of initial preferences.
► It may enhance our ability to explore complex, uncertain, and value-laden issues.
► Frontier of backcasting is increasingly participatory and makes use of visual tools.
► Possible tradeoff between number of people engaged and depth of discussion/learning.
