For many of us, the holiday season can mean delightful overeating, followed by recriminatory New Year’s resolutions.
But eating enough and no more should be on the menu for all of us, according to a recent UBC study. It found that 44 per cent of us would need to change our diets for the world to warm no more than 2 C.
Dr. Juan Diego Martinez, who led the research as a doctoral student at UBC’s Institute for Resources, Environment and Sustainability, discusses the study’s findings and the simple dietary changes we can all make.
The Universitat Jaume I in Castelló will develop six research and innovation projects in areas such as environmental sustainability and risk detection to improve disaster response through funding obtained in the competitive call for proposals from the Valencian Innovation Agency (AVI) (IVACE+e innovación) 2025, which seeks to promote innovation, R&D transfer and collaboration between universities, technology centres and companies.
The UJI has obtained funding in three lines of the call financed by the European Union within the framework of the European Regional Development Fund (ERDF) Programme for the Valencian Community 2021-2027 – IVACE+ for an amount of nearly one million euros, with which it will promote six projects with direct technological and social impact to respond to real challenges.
The various initiatives led by UJI research staff will provide innovative solutions in the field of environmental sustainability through advanced technologies to improve water quality and management, strengthen the circular carbon economy, promote cleaner and safer production systems aligned with green technology, and strengthen the innovation ecosystem through materials with a lower environmental impact. They also seek to anticipate responses to situations of risk due to natural disasters resulting from climate change.
Healthy, sustainable school meals could cut undernourishment, reduce diet-related deaths and significantly lower environmental impacts, according to a new modelling study led by a UCL (University College London) researcher.
Researchers typically analyze images taken by geostationary satellites to identify regions of the sky where contrails form, but new research shows adding images taken by low-Earth-orbiting satellites would help identify many more such regions. Pilots could avoid these regions to reduce aviation’s climate impact.
Wildfires may disappear from the landscape within weeks, but their hidden effects on the soil can persist for decades. An international research team led by the University of Göttingen, together with partners in Tübingen, Berlin and Chile, has shown how wildfires in humid temperate rainforests and mediterranean woodlands of central Chile lead to very different pathways of soil recovery and ecosystem resilience. The study shows that soil structure and nutrients continue to change for more than a decade after a fire. The results were published in the journal Catena.
