Trees, shrubs, and other plants along roads and sidewalks play an important role in making cities more resilient to climate change, improving public health, and advancing environmental justice. Yet, tracking its distribution and change over time remains a major challenge – especially across large, rapidly urbanizing regions of the world. A new IIASA-led study addresses this gap.
After an unseasonably hot early May in Vienna, the European Geoscience Union (EGU) General Assembly concluded, having gathered more than 19,000 scientists, practitioners, and policymakers from around the globe. Themes of vulnerability, compounding risk, and systemic transformation took centre stage, reinforcing the need for grounded, science-informed resilience-building. Alliance colleagues from the Z Zurich Foundation, IIASA, and Concern Worldwide share their reflections on this year’s General Assembly.
At the IAMO Forum 2025, Roman Hoffmann will deliver a keynote titled "Migration and Immobility in a Changing Climate: The Role of Compound Risks for Well-Being and Livelihoods". His talk will shed light on how climate-related risks shape both migration decisions and immobility, emphasizing the profound implications for livelihoods and sustainable development in vulnerable regions.
The Global Assessment Report is the defining report on the state of art and future on disaster risk. The comprehensive 2025 report comes 10 years after the Sendai Framework, where the global community agreed to further prevent the creation of new risk, reduce existing risk and increase resilience.
In partnership with our regional member, the Sub-Saharan Africa Regional Member Organization (SSARMO), IIASA will co-host two sessions during the Sustainability Research and Innovation Congress 2025 (SRI2025) Africa Satellite Event, and has been invited to contribute to a pre-conference workshop by delivering a half-day training session on systems analysis.
On 17 June, Sigrid Stagl, Scientist of the Year 2024, will speak on the topic of the sustainable economy. Ulrike Diebold, Vice President of the Austrian Academy of Sciences (OeAW), IIASA Director General Hans Joachim (John) Schellnhuber, and Christian Köberl, IIASA Council member for Austria, will deliver opening remarks before the lecture. This event is part of the ongoing IIASA-OeAW public lecture series and will be in German.
IIASA Deputy Director General Karen Lips represented the Institute at last week’s Austria–Vietnam High-Technology and Innovation Forum in Vienna. Following her participation in a high-level panel discussion on digital transformation, a Memorandum of Understanding (MoU) was signed with the Vietnam Posts and Telecommunications Group (VNPT) to boost collaboration in AI and digital transformation.
The Climate and Clean Air Coalition (CCAC), in partnership with the International Institute for Applied Systems Analysis (IIASA), Stellenbosch University and the African Centre for Clean Air (ACCA) is providing financial and technical support to the country through the National Environment Management Authority (NEMA) to implement the Uganda - Sector strategy for Organic Waste Management.
