IIASA, the European Commission’s Joint Research Centre (JRC), and the Population Division of the United Nations Department of Economic and Social Affairs (UNDESA) have joined forces to conduct a survey among world experts in demography to better understand the future of the world population and its impact on various global trends.

Many global trends including economic, environmental, social, and geopolitical changes, depend on the future of the world population. Effectively assessing the future world population is therefore key to better responding to future societal challenges. Current long-term global population projections are based on a variety of methodologies and assumptions employed by leading demography institutions and yield varied results in terms of projected population size and structure – in particular for projections for the second half of the 21st century.

The survey invites experts to express their opinion on the consequences of demographic change for climate change, environmental sustainability, and the economy as well as the role of population policies to address them. It is aimed at the main international associations in population studies and the results will be made available in a dedicated report in September 2023.

“We urgently need to reflect on the ingredients that go into making population projections. We owe this to the users and in particular to the policymakers who will use the projections to inform their decisions. This survey will help us to do just that,” says IIASA Population and Just Societies Program Director, Anne Goujon.

If you want to have more details on this initiative or if you are an expert in demography and would like to take part in the survey, please contact: EC-kcmd@ec.europa.eu

FLAM Sparks Interest and Conversation at the 2023 IBFRA Conference in Helsinki

Boreal forests often bring to mind a winter wonderland: spruce and pine forests as far as the eye can see, fluffy snow dotted with reindeer beneath a nighttime sky brightened by the aurora borealis. Climate change threatens this fragile, pristine habitat that spans 8 countries in the far north. Now boreal forests are associated not just with snowy landscapes, they are becoming synonymous with raging wildfires and massive plumes of smoke, such as those found currently in Canada. Mitigating the threats posed by climate change in this unique ecosystem and discussing the most recent boreal-related research is the focus of the International Boreal Forest Association conference. Organized in large part by IIASA’s own Florian Kraxner, IBFRA 2023 was held in Helsinki, Finland, where researchers from around the globe gathered to discuss recent findings, foster new connections, and contribute to a plan of attack to save boreal forests as we know them.
