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.
POPJUS Research Groups
Equity and Justice (EQU)
The EQU Group focuses on the human dimension of selected globally relevant policy challenges, with the aim of delineating and advancing their analysis, management, and governance with special attention paid to the design and application of equity and justice frameworks, both within the group and across IIASA.
Migration and Sustainable Development (MIG)
MIG focuses on applying advanced data collection and estimation methods to quantify and better understand the trends, patterns, drivers, and consequences of different types of migration considering its interactions with the social, economic, and environmental dimensions of sustainable development.
Multidimensional Demographic Modeling (MDM)
Through its research, the MDM Group aims to advance demographic modeling methods to assess and forecast population dynamics with a focus on demographic and spatial heterogeneity under different socioeconomic scenarios at the global, national, and sub-national level.
Young Scientists Summer Program
The Young Scientists Summer Program (YSSP) at IIASA offers an exceptional opportunity for PhD students to engage in collaborative research with IIASA's interdisciplinary teams.
