A just-published study coins a new metric: the "mortality cost of carbon." That is, how many future lives will be lost--or saved--depending on whether we increase or decrease our current carbon emissions. If the numbers hold up, they are quite high.
The EU funded project DAFNE has developed a methodology for avoiding conflicts of use in transboundary rivers. The model-?based procedure allows for participatory planning and cooperative management of water resources. The aim is now for the DAFNE methodology to be implemented in other regions of the world.
More than 820 million people in the world don't have enough to eat, while climate change and increasing competition for land and water are further raising concerns about the future balance between food demand and supply. The results of a new IIASA-led study can be used to benchmark global food security projections and inform policy analysis and public debate on the future of food.
An international research team has come up with an innovative method for metal recovery from industrial waste. The new method allows the simultaneous recovery of multiple metals from waste oxides in a single process. This novel route will lower the burden on waste storage facilities with significant contributions to the economic and environmental sustainability of industrial waste management. The study was published in Journal of Environmental Management.
Restoration of degraded drylands is urgently needed to mitigate climate change, reverse desertification and secure livelihoods for the two billion people who live there, experts warn in a major new paper in Nature Ecology & Evolution. Scientists leading the Global Arid Zone Project examined restoration seeding outcomes at 174 sites on six continents, encompassing 594,065 observations of 671 plant species - with the lessons learned important to meeting ambitious future restoration targets.
Researchers created a simulation of a deep-sea sponge and how it responds to and influences the flow of water. The work revealed a profound connection between the sponge's structure and function, shedding light on both the basket sponge's ability to withstand the dynamic forces of the surrounding ocean and its ability to create a vortex within the body cavity "basket." These properties may help for the design of ships, planes and skyscrapers of the future.
In the Alpine foothills, in low mountain ranges, or on the seacoast, expansion of wind energy use often meets popular resistance. Researchers of Karlsruhe Institute of Technology (KIT) and partners from Great Britain and Denmark have now studied what this means for the energy transition. In Patterns, they report that costs per kilowatt hour may rise by up to 7 cents and CO2 emissions may increase by up to 200 g. (DOI: 10.1016/j.patter.2021.100301)
The economic and environmental pros and cons of melting Arctic ice creating shorter shipping routes through the polar region are weighed up in ground-breaking research from UCL experts in energy and transport. They conclude that policy makers must properly assess the environmental trade-offs and costs in addition to the commercial benefits and opportunities in Arctic shipping. The authors also want to see more incentives to drive technological developments that will accelerate the uptake of green fuels and technologies.
Michigan State University ecologists led an international research partnership of professional and volunteer scientists to reveal new insights into what's driving the already-dwindling population of eastern monarch butterflies even lower.
Downstream water supply and economic losses could substantially disrupt Egypt, according to a new USC analysis that offers potential solutions to avoid conflict over the dam.
