Spatial variation in determinants of agricultural land abandonment in Europe - ScienceDirect

Spatial variation in determinants of agricultural land abandonment in Europe - ScienceDirect | Biodiversité | Scoop.it
Agricultural abandonment is widespread and growing in many regions worldwide, often because of agricultural intensification on productive lands, conservation policies, or the spatial decoupling of agricultural production from consumption. Abandonment has major environmental and social impacts, which differ starkly depending on the geographical context, as does its potential to serve as a land reservoir for recultivation.

Next 10 years critical for achieving climate change goals

Next 10 years critical for achieving climate change goals | Biodiversité | Scoop.it
Carbon dioxide (CO2) and other greenhouse gases in the atmosphere can be reduce in two ways—by cutting our emissions, or by removing it from the atmosphere, for example through plants, the ocean, and soil.

Polar bears are starving, and this video reveals why

Polar bears are starving, and this video reveals why | Biodiversité | Scoop.it

Polar bears rely on sea ice to get their primary meal: seals. But as climate change melts this ice, the bears have to work harder to find prey, and that’s taking a toll on their health, researchers report today in Science. To find out how much the animals need to eat, scientists captured nine female polar bears living in the Beaufort Sea each spring for 3 years and took blood samples and other measurements to gauge the bears’ metabolisms. Then they attached GPS collars affixed with video cameras and accelerometers to watch the bears forage for food.

Vie numérique, urbaine et climat

Vie numérique, urbaine et climat | Biodiversité | Scoop.it

Hospitalisations massives à cause des fortes chaleurs, moussons meurtrières, famines... la chronique des impacts sociétaux et économiques du réchauffement climatique, d'année en année plus dramatique, témoigne de l'urgence climatique. Certes, le numérique est un des leviers de la transformation de nos modes de vie dans nos villes et territoires, mais à condition que le citoyen en écrive la feuille de route.
