A Diverfarming project study compares the environmental footprint and the economic performance of traditional mandarin monocropping as opposed to growing mandarin intercropped with herbaceous crops and the use of deficit irrigation

In a study published in Addiction that analyzed 2015–2018 information from 47 countries, approximately 1 in 12, or 8.6%, of adolescents reported vaping in the past 30 days. Countries with higher tobacco taxes tended to have higher adolescent vaping.

Proponents of degrowth have long argued that economic growth is detrimental to the environment. Now, scientists show that concerning the food sector, curbing growth alone would not make our food system sustainable – but changing what we eat and putting a price on carbon would. In a first, a group led by the Potsdam Institute used a quantitative food and land system model to gauge the effects of degrowth and efficiency proposals on the food sector’s greenhouse gas emissions. They find that combining a dietary shift, emissions pricing, and international income transfers could make the world’s food system emissions-neutral by the end of the 21st century – providing at the same time a healthier nutrition for a growing world population.

A team of researchers from Simon Fraser University have returned to the scene of a massive 2018 landslide as part of a project aimed at preventing future extinction-level events. On Nov. 1, 2018, the Big Bar landslide in British Columbia blocked the Fraser River, prevented salmon from getting back to their spawning grounds in the Upper Fraser Basin and threatened the future of the species. Remediation efforts are still ongoing, but researchers led by SFU are back at Big Bar to map the effects of the slide. Their work is part of a larger project aimed at assessing and mitigating the risk of landslides to critically important salmon in the Fraser River.
