IIASA Director General Hans Joachim (John) Schellnhuber visited Barbados at the end of May to deepen engagement with government, academic, diplomatic, and international partners and explore new opportunities for collaboration on resilience, innovation, and sustainable development for Small Island Developing States (SIDS).
Global migration has risen sharply from approximately 13 million people per year in 2000 to around 35 million people per year in 2023. This is according to a new dataset on human migration published in Nature by researchers from the London School of Economics and Political Science (LSE), IIASA, and the University of Hong Kong.
Social networks may help protect cognitive functioning in later life, particularly among older adults who are no longer working, according to a new IIASA-led study. Drawing on data from 27 European countries, the researchers found that social connections can help compensate for the loss of mentally stimulating interactions linked to work, with different types of relationships benefiting women and men.
As global temperatures continue to rise beyond the 1.5°C threshold, understanding the implications of climate overshoot has become one of the defining scientific and policy challenges of our time. Following the success of the inaugural Overshoot Conference in Laxenburg, Austria, the second Overshoot Conference will take place from 24–25 November 2026 in Beijing, China, bringing together leading researchers, policymakers, innovators, and communicators to advance the global dialogue on overshoot pathways and responses.
New research from IIASA and the University of Oxford provides the first quantitative evidence that drought exposure over the last 12 months is associated with increased risk of sexual, emotional, and physical violence among adolescents in Southern Africa. This risk rises substantially during cumulative droughts over two years.
Titled “Integrated Systems Analysis of Ecosystems: The Land, Water, Food, and Climate Nexus”, the publication brings together expertise from IIASA and leading Chinese researchers to address the interconnected challenges of ecosystem sustainability, food security, and climate resilience.
A high-level delegation from the Ministry of Science and Technology of China (MoST) and representatives of the Embassy of the People’s Republic of China in Austria visited IIASA at Schloss Laxenburg on 13 May 2026 for discussions on scientific cooperation, science diplomacy, and future collaboration.
Nexus of Sustainability: Understanding of FEWSE Systems II is a 2026 Springer monograph detailing the interdependencies between food, energy, water, society, and the environment (FEWSE). It focuses on risk management, robust modeling, and sustainable development, featuring recent research of the joint research project between IIASA and National Academy of Sciences of Ukraine (NASU, Ukraine NMO at IIASA) on “Integrated modeling for robust management of food-energy-water-land use nexus for sustainable development”.
Researchers from the International Institute for Applied Systems Analysis (IIASA) contributed to the Expert Round Table on Climate Misinformation, organized within the framework of the MIP4Adapt initiative. MIP4Adapt (Mission Implementation Platform) is the central support mechanism for the EU Mission on Adaptation to Climate Change, aiding regions and local authorities in planning and implementing climate resilience strategies. It provides technical assistance, community building, and funding guidance to Charter signatories.
Persistent methane emissions from sectors such as agriculture and growing debates over the credibility of carbon offsets are creating new challenges for governments and companies pursuing net-zero commitments. New research suggests temporary carbon storage may have a scientifically valid role in helping support climate goals, if used in the right way.
A recent Table.Briefings article featuring comments by IIASA Director General Hans Joachim (John) Schellnhuber highlights growing concerns that progress in decarbonizing the global buildings sector remains too slow to achieve international climate goals. The article discusses findings from the new UNEP and Global Alliance for Buildings and Construction (GlobalABC) Global Status Report for Buildings and Construction 2025/2026.
