Askoa Ibisate, geographer specialising in fluvial geomorphology, has analysed how the disappearance of the Olloki dam affects sediment transport. Ibisate concluded that the volume of pebbles mobilised by the demolition has increased, and their journey has been extended. The results are particularly significant because the monitoring work has been ongoing for seven years and the authorities are provided with valuable information for predicting the consequences of dam demolition.
Farmers are always looking for smarter ways to boost crop health, and one of the industry’s latest game-changers is polymer-coated, controlled-release fertilizers (PC-CRFs). These high-tech soil enhancers deliver nutrients gradually, ensuring plants get exactly what they need when they need it without the waste of traditional methods.
While PC-CRFs can boost crop efficiency, a new study from University of Missouri researcher Maryam Salehi and collaborators uncovers a downside — microplastic pollution. As the polymer coatings break down in the soil, they release tiny plastic particles into the environment.
A century of fire suppression, climate change, and drought has worsened wildfires in the Western U.S. While prescribed burns help reduce fuel, a “fire deficit” increases wildfire risks, with significant health and environmental impacts. Deforestation and pests further limit carbon storage. Emulating Indigenous practices, a new study shows that combining physical harvesting of dead wood with thinning reduces wildfire risks, lowers carbon emissions, and boosts carbon storage through products like biochar.
