The POPJUS Program continues and builds upon research activities previously undertaken in the IIASA World Population and Risk and Resilience programs. Insights into current and future population sizes, structures, and distributions are fundamental to understanding human impacts on ecosystems and simultaneously, the impact of environmental changes on human wellbeing differentiated by sub-populations.

The program’s research agenda embraces the key priority in the IIASA strategic plan by identifying sustainable development challenges and exploring people-centric systems solutions for sustainable, resilient, just and equitable societies. The program focuses on strengthening the human-centered and population-based approach, taking into consideration equity and the just distribution of opportunities, outcomes, and processes. In doing so, the program builds on existing strengths and expertise in population and human capital modeling as well as expertise in understanding, managing, and equitably governing systemic and existential risks associated with global change. The program will continue to invest in advancing its methods, approaches, and data to deliver results that can be incorporated into system analytical models, inclusive policy processes, and ultimately into equitable and effective policy pathways and transformations.

Fact Sheet Climate Change and Demography

The reciprocal relationships between human populations and the environment becomes increasingly important in the light of climate change. Researchers from IIASA and Wittgenstein Centre published the Fact Sheet Climate Change and Demography, providing information for policy makers and scientists about some key areas where demography can contribute to climate research.

stakeholder groups
Social and policy simulations, as well as serious games, are participatory processes through which diverse societal stakeholders collectively explore a complex reality and complex challenges. These participatory processes combine both social and natural science insights to foster experiential learning. They enable participants to make sense of the complexity associated with policy issues, and reflect on system inter-linkages and stakeholder plurality. These methods have become increasingly recognised for informing and guiding policy in complex settings, including sustainable development, climate change mitigation/adaptation and disaster risk reduction.
