@gerrymcgovern La situation en Arizona, où une ferme saoudienne utilise d'énormes quantités d'eau souterraine pour irriguer des cultures, soulève des préoccupations similaires à celles observées dans le Kentucky, où la salinisation des terres est un problème croissant. L'irrigation excessive et l'utilisation d'eaux de forage peuvent entraîner une accumulation de sels dans le sol, dégradant ainsi la qualité des terres agricoles. #Salinisation #AgricultureDurable #Eau #Environnement

#Vietnam farmers struggle for fresh #water as drought brings salinisation

"The area is crisscrossed by waterways, but the prolonged #heatwave and lack of rain are causing #salinisation -- the intrusion of salt water from the sea -- badly affecting crops in a region vital to feeding the nation of 90 million people."

The #MekongDelta faces #Saltwater intrusion every year, but more intense hot weather and rising sea levels -- both driven by #ClimateChange -- are increasing the risk.

The delta, which provides food and livelihoods for tens of millions of people, faces nearly $3 billion a year in #CropLosses as more #saltwater seeps into arable land. #RisingSeas

The damage would likely centre on the #MekongDelta region, known as "#Vietnam's rice bowl" because it provides food and livelihoods for tens of millions of people, research from the country's environment ministry showed. #RisingSeas #FoodSecurity #Salinisation

Vietnam faces $3bn annual #CropLosses from rising #SaltWater levels

Decrease of crop yield in low lying coastal areas as well as irrigated (dry land) agricultural areas :

Reason : increased salinity in agricultural soils, major driver of soil degradation

=> pressure on conventional farming based on freshwater resources.
