Human interventions to harness water resources, such as reservoirs, dams, and irrigation measures, have increased water availability for much of the global population, but at the same time, swept water scarcity problems downstream.
New measures of aging, combined with UN population projections, show that population aging is likely to end before 2100 in China, Germany, and the USA.
More targeted efforts are needed from both the public and private insurance sectors in order to encourage people to take action to reduce their risk of flood damage, according to a new study of three European countries.
● Higher exposure to secondary particles and ozone can be traced back to excess NOx emissions from diesel cars, vans and light commercial vehicles. ● With the EU’s vehicle emission limits achieved on the road about 5,000 premature deaths could be avoided annually. ● If diesel cars emitted as little NOx as petrol cars, about 7,500 premature deaths could be avoided annually.
Efforts to reduce greenhouse gas emissions from the agriculture and forestry sectors could lead to increased food prices—but new research identifies strategies that could help mitigate climate change while avoiding steep hikes in food prices.
Switching from using fuelwood to liquefied petroleum gas (LPG) for cooking would provide modest climate benefits, but the extent of these depend on whether the wood is renewably sourced, and if the short-lived emissions from burning wood are taken into account, according to a new analysis focused on India.
A new study published in nature Sustainability proposes alternative hunger eradication strategies that will not compromise environmental protection.
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.
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.
When researchers or policymakers ask health related questions–which they do a lot–they often rely on self-reported rather than tested health data. Researchers looked into how reliable this type of data is for research and found that self-reported data could be highly biased.
Monitoring progress on the UN Sustainable Development Goals requires a huge amount of data. Citizen science could help fill important data gaps, say IIASA researchers.
Although the mapping of aboveground biomass is now possible with satellite remote sensing, these maps still have to be calibrated and validated using on-site data gathered by researchers across the world.
