flooding in europe to double
2014-03-03 05:46:00

International Institute for Applied Systems Analysis Losses from extreme floods in Europe could more than double by 2050, because of climate change and socioeconomic development. Understanding the risk posed by large-scale floods is of growing importance and will be key for managing climate adaptation. Current flood losses in Europe are likely to double by 2050, according to a new study published in the journal Nature Climate Change by researchers from the International Institute for...

Mitigating Climate Change Through Livestock System Transitions

[ Watch the Video: Changing Livestock Diets Could Help Reduce Emissions ] International Institute for Applied Systems Analysis Livestock production is responsible for 12% of human-related greenhouse gas emissions, primarily coming from land use change and deforestation caused by expansion of agriculture, as well as methane released by the animals themselves, with a lesser amount coming from manure management and feed production. “There is a lot of discussion about reduction of meat...

Wealth inequality can encourage people to cooperate when they would otherwise have no incentive to do so, according to a new study published in Nature Communications. "In many groups and societies, the temptation to defect is high, which means that cheaters are much better off than cooperators," says IIASA researcher Ulf Dieckmann, who worked on the study along with IIASA researcher Ádám Kun. For example, he says, if a train ticket is very expensive and the probability that cheaters are...

Trade-offs Between Food Security And Climate Change Mitigation Addressed By New Study
2013-07-16 12:20:30

International Institute for Applied Systems Analysis Improving crop yields using sustainable methods could cut greenhouse gas emissions by as much as 12% per calorie produced according to a new study published in the journal Environmental Research Letters. At the same time, these changes could provide more food to people in need. Agriculture and land use change contributed about 1/3 of total human greenhouse gas emissions in the past decade, through crop cultivation, animal production,...

Study Shows Travel Choices For A Smaller Carbon Footprint
2013-06-17 12:52:02

International Institute for Applied Systems Analysis Planes, trains, or automobiles: what's the most climate-friendly way to travel? A new study by researchers from IIASA and CICERO brings better estimates of how much personal travel impacts the climate. The study, published in the journal Environmental Science and Technology by researchers at IIASA and Center for International Climate and Environmental Research (CICERO) calculates the climate impact for passenger trips of 500-1000...

The new study in Nature Climate Change shows that reaching the 3 energy-related objectives proposed by the United Nations in their Sustainable Energy for All (SE4All) initiative, launched in 2011, would reduce emissions of greenhouse gases that contribute to climate change and, in combination with other measures, could help keep global temperature rise from exceeding the internationally agreed target level of 2°C. "Achievement of the 3 objectives would provide an important entry point...

The study, by IIASA Evolution and Ecology Program postdoctoral fellow Tatsuya Sasaki, provides a simple new model that ties punishment by social exclusion to the benefits for the punisher. It may help explain how social exclusion arose in evolution, and how it promotes cooperation among groups. "Punishment is a common tool to promote cooperation in the real world," says Sasaki. "And social exclusion is a common way to do it." From reef fish to chimpanzees, there are many examples of...

Picky females play a critical role in the survival and diversity of species, according to a Nature study by researchers from the University of British Columbia and the International Institute for Applied Systems Analysis (IIASA) in Austria. To date, biodiversity theories have focused on the role played by adaptations to the environment: the species best equipped to cope with a habitat would win out, while others would gradually go extinct. The new study presents the first theoretical model...

For many people in the developing world getting enough food to eat is a persistent challenge. However the challenge does not stop there. A new issue of the international journal Energy Policy details the human and environmental cost of cooking food using the only energy source available to many people, woody biomass.  The Special Issue explores the type of decision frameworks that are needed to guide policy development for clean cooking fuels and to ensure that the provision of clean...

Projections of future population trends that do not explicitly include education in their analysis may be flawed Future trends in global population growth could be significantly affected by improvements in both the quality and quantity of education, particularly female education. Projections of future population trends that do not explicitly include education in their analysis may be flawed, according to research published today in the journal Science (July 29 2011). The study uses a novel...
