Vanishing Sands: Losing Beaches to Mining In a time of accelerating sea level rise and increasing…

"Vanishing Sands: Losing Beaches to #Mining" exposes the #sandmining crisis. Written by marine geologist Orrin H. Pilkey and a team of interdisciplinary experts, we learn how sand is ecologically irreplaceable when removed from dynamic #sediment systems.

How does sand mining reshape rivers?

@drchrishackney.bsky.social explores how #sandmining is transforming riverbeds in the #MekongRiver, #Cambodia. His work shows that bedforms become larger, steeper, and rougher than natural ones, altering flow and #sediment dynamics!

[8/8] Les auteurs concluent que la survie du Tonlé Sap dépend d’une gouvernance régionale des sédiments et d’un contrôle transfrontalier des extractions. Sans cela, le lac, pilier écologique et économique du Cambodge, pourrait devenir un bassin stagnant d’ici 2050. #geography #sandmining #Mekong

[7/8] L’étude identifie l’extraction de sable comme cause dominante. Le Cambodge a extrait 59 millions de tonnes de sable en 2020, soit dix fois le flux naturel de sédiments du Mékong. Ce commerce, largement illégal, alimente les marchés de Singapour et du Vietnam. #geography #sandmining #Mekong

[5/8] Les variations du "pouls de crue" créent un déséquilibre hydrologique majeur. En saison humide, les crues sont 26 km³ + fortes, mais les sécheresses sont prolongées. Ce basculement déstabilise les rizières et les écosystèmes du delta, déjà vulnérables au climat. #geography #sandmining #Mekong

[4/8] La surface maximale du lac diminue de 40%, passant de 12.600 à 7.600 km². Le Tonlé Sap perd alors son rôle de "cœur battant" du Mékong. Les flux de retour vers le delta vietnamien baissent de 59% en saison sèche, accentuant salinisation et insécurité hydrique. #geography #sandmining #Mekong

[3/8] Les chercheurs montrent qu’entre 1998 et 2018, le lit du #Mékong s’est creusé de 3m en moyenne sous l’effet du dragage et des barrages. Cela a réduit de 47% le volume d’eau entrant ds le Tonlé Sap. Les modèles prévoient une chute de 69% d’ici 2038 si rien ne change. #geography #sandmining

How sand mining is eroding rivers, livelihoods and cultures Sand mining destabilises riverbeds and affects local communities but new hi-tech surveillance can improve the monitoring of extraction and help protect these people.

Das Sandmining an den Küsten der Ozeane und den Flußufer führt zur Erosion der Küsten und Flussbetten. Es wird immer dringender Wüstensand so zu verändern, das er als Zuschlag für Baumaterial geeignet ist.
