Implications pour la disponibilité de l'eau douce
À l'heure actuelle, le #pompage excessif des eaux souterraines est le principal facteur contribuant aux taux de déclin en #stockage de l'eau terrestre dans les régions en voie d'assèchement, amplifiant de manière significative les impacts de l'augmentation de la #température, de l'#aridification et des épisodes de #sécheresse extrême. La #surexploitation continue des eaux souterraines qui, dans certaines régions comme la #Californie, se produit à un rythme croissant, plutôt qu'à un rythme durable ou décroissant, compromet la sécurité régionale et mondiale de l'eau et de l'alimentation d'une manière qui n'est pas pleinement reconnue dans le monde entier.
L'épuisement des eaux souterraines est directement affecté par les décisions de gestion de l'eau et peut également être stoppé par celles-ci.
Dans de nombreux endroits où les eaux souterraines s'épuisent, elles ne se reconstitueront pas à l'échelle humaine. La disparition des eaux souterraines des #aquifères de la planète constitue une nouvelle #menace grave pour l'humanité et présente des #risques en cascade qui sont rarement pris en compte dans les #politiquesenvironnementales, la #gestion et la #gouvernance.

Southwestern #drought likely to continue through 2100, research finds
Southwestern #US is experiencing a #megadrought resulting in the #aridification of the landscape, a decades-long drying of the region brought on by climate change and the overconsumption of the region’s #water.
Using an ensemble of historical and future #climate models forecasting climate and precipitation patterns until 2100, they found that the PDO-like negative phase continues through this century.

The #cactus family’s surprising evolutionary journey https://www.newscientist.com/article/2448468-the-cactus-familys-surprising-evolutionary-journey/
Identifying the multiple drivers of cactus diversification https://www.nature.com/articles/s41467-024-51666-2
"ancient #aridification – an increase in dryness seen in several American regions – cannot fully explain cactus #evolution. Some big periods of diversification seem to have happened more recently than the transition to a drier #climate, for example, and new species seem to have emerged more quickly in places that aren’t as dry."
