IIASA researchers contributed to a new study showing that efforts to meet restoration targets for the globally important, biodiversity rich forests found along Brazil’s Atlantic coast will only be effective with a sustainable intensification of cattle farming.

Focusing on Sweden, a new IIASA study assessed the feasibility of recovering phosphorus from municipal wastewater as an alternative sustainable source of this non-renewable mineral.

IIASA Director General Hans Joachim (John) Schellnhuber spoke to Falter's Katharina Kropshofer about why tipping elements in the Earth system are so difficult to predict.

Despite advancements in clean energy, global CO₂ emissions continue to rise. IIASA researchers contributed to a new international study that underscores the importance of integrating technological advancements with robust institutional capacities to formulate effective climate policies.

Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5°C of global warming after a period of overshoot. A new study indicates that these risks can be minimized if warming is swiftly reversed.

A new IIASA-led study offers the first detailed estimates of land use change emissions for six sustainable aviation fuel production pathways. The authors focused on both food and non-food raw materials used to produce biofuels, using trusted global data sources to provide fine-scale emissions data.

Despite facing regional threats like deforestation and wildfires, the world's forests continue to be a powerful weapon in the fight against climate change. A new study reveals these vital ecosystems have consistently absorbed carbon dioxide for the past three decades, even as disruptions chip away at their capacity.

A novel machine learning framework developed by IIASA researchers to estimate global rooftop area growth from 2020 to 2050 can aid in planning sustainable energy systems, urban development, and climate change mitigation, and has potential for significant benefits in emerging economies.

The Russian invasion of Ukraine and the consequent displacement of millions of people will have a significant impact on the country’s long-term population structure. Researchers from the Austrian Academy of Sciences, IIASA, and the University of Vienna are forecasting a substantial population decline of 21-31% by 2052.

Global water scarcity, a result of both quantity and quality change, challenges the achievement of the Sustainable Development Goals. An international team of researchers developed a novel modeling approach to identify cost-effective combinations of water management, promising a substantial reduction in future water scarcity.  

A new IIASA study explores waste management systems and reveals that achieving zero waste leakage by 2030 is unlikely, potentially jeopardizing related Sustainable Development Goals. The authors emphasize the need for global cooperation, particularly across four regions, to responsibly manage waste disposal.

IIASA researchers contributed to a new study, analyzing the main narratives in public discussions of climate change on social media.

Small changes in our everyday actions can trigger significant, rapid societal shifts especially when it comes to climate action. A new IIASA-led study highlights the importance of analyzing these dynamics with a comprehensive framework to harness their full potential for reducing carbon emissions.

Global crop modelers and IIASA scientists joined forces to explore the potential impacts of nuclear winter resulting from hypothetical nuclear detonations on food systems and food security.

A new study conducted by IIASA researchers and their colleagues highlights that cooperation in infrastructure operation between countries surrounding the Lancang-Mekong River Basin could bring major economic and environmental co-benefits.

A perspective piece published in Nature Climate Change describes innovative strategies that significantly reduce both resource consumption and fossil fuel emissions.

IIASA Director General John Schellnhuber in an interview with Katharina Kropshofer at Falter.

New research by the Norwegian University of Life Sciences (NMBU) and IIASA proposes using soil bacteria to cut greenhouse gas emissions from food production.

Urbanization in Africa is accelerating quickly, showing no signs of slowing down. An international team of researchers addresses critical gaps in our understanding of how this urbanization affects local food and ecological systems, emphasizing the importance of recognizing shifts in dietary patterns.

Global biodiversity has declined between 2% and 11% during the 20th century due to land-use change alone, according to a large multi-model study published in Science. The projections show that climate change could become the main driver of biodiversity decline by the mid-21st century.
