The long arm of childhood conditions

Available research on the impact of a person’s socioeconomic status during childhood suggests that the circumstances one grows up in matter a great deal for adult health. The results of a new IIASA study supports the notion of a “long arm of childhood conditions” that remains invisible beyond mid-life but can affect health satisfaction later in life.  More

21 October 2019
A roadmap to make the land sector carbon neutral by 2040

Land is critical to human livelihoods and wellbeing, while actions related to land use also play an important role in the climate system.

08 October 2019
Who is telling the truth about their health?

When researchers or policymakers ask health related questions – which they do a lot – they often rely on self-reported rather than tested health data. IIASA researchers looked into how reliable this type of data is for research and found that, depending on country or age, self-reported data could be highly biased.  More

25 September 2019
Assessing the effects of climate change on future wheat production

Wheat is the world’s largest rain-fed crop in terms of harvested area and supplies about 20% of all calories consumed by humans. A new study has found that unless steps are taken to mitigate climate change, up to 60% of current wheat-growing areas worldwide could see simultaneous, severe and prolonged droughts by the end of the century.  More

Exposing the dirty footprint of the broken grid

A newly released report by the International Finance Corporation (IFC) shows that fossil fuel-burning backup generators in developing countries produce as much energy as 700-1,000 coal-fired power stations, consume US$50 billion in annual spending, and emit dangerous chemicals into homes and businesses.  More

18 September 2019
Rethinking scenario logic for climate policy

Current scenarios used to inform climate policy have a weakness in that they typically focus on reaching specific climate goals in 2100 – an approach which may encourage risky pathways that could have long-term negative effects. A new IIASA-led study presents a novel scenario framework that focuses on capping global warming at a maximum level with either temperature stabilization or reversal thereafter.  More

How can we feed the world without overwhelming the planet?

Sustainable Development Goal (SDG) 2 calls for ending hunger, achieving food security and improved nutrition, and promoting sustainable agriculture. The environmental challenges posed by agriculture are however massive, and many fear that they will only become more pressing as we try to meet the growing need for food worldwide. IIASA researchers and colleagues from Japan propose alternative hunger eradication strategies that will not compromise environmental protection.  More

26 August 2019

19 August 2019
Uncertainty in emissions estimates in the spotlight

National or other emissions inventories of greenhouse gases that are used to develop strategies and track progress in terms of emissions reductions for climate mitigation contain a certain amount of uncertainty, which inevitably has an impact on the decisions they inform. IIASA researchers contributed to several studies in a recently published volume that aims to enhance understanding of uncertainty in emissions inventories.  More

07 August 2019
Observation-driven research to inform better groundwater management policies

Groundwater maintains vital ecosystems and strongly influences water and energy budgets. Although at least 400 million people in sub-Saharan Africa depend on this valuable resource for their domestic water needs, the processes that sustain it and their sensitivity to climatic variability, are poorly understood. IIASA contributed to a study that looked into climate impacts on groundwater in light of changing climatic patterns in Africa.  More

17 July 2019
Lifting the fog on carbon budgets

The concept of a carbon budget has become a popular tool in guiding climate policy since the Intergovernmental Panel on Climate Change’s (IPCC) Fifth Assessment Report was released in 2014. IIASA researchers were involved in the development of a framework that can help scientists determine which factors affect the size of the remaining carbon budget and how they interact.  More

04 June 2019
Is there a demographic need for migration in Europe?

A European Commission-IIASA flagship report has found that an increase in the EU population aged 65+ is certain – regardless of higher fertility or migration. However, raising labor force participation (particularly for women) and improved education of natives and migrants have the power to nullify aging-related worries.  More
