Participatory Demographic Scenarios Addressing Uncertainty and Transformative Change in Ethiopia

Projections on future population trends provide important decision support, however are confronted with high uncertainty. In contexts of low data quality, missing and contradicting knowledge on drivers of change, such as in many developing countries, participatory scenarios can support the quality of assumptions needed for quantitative projections. We present a scenario approach designed for contexts of uncertain and missing demographic data and illiteracy, which was successfully tested in three study sites in North-West Ethiopia. The four qualitative scenarios for 2030 supported the inter-subjective definition of assumptions for the calculations, which were again validated by members of the rural communities. We argue that the participation process has resulted in more robust and context-specific projections. The collaborative work on the local drivers of demographic change between science and society provided a valuable space for social learning, so that local stakeholders could identify the need for and scope of local mitigation or adaptation measures to demographic transformation.
