L'amministrazione Biden ha reso noto che la carenza d'acqua nel fiume Colorado ha oltrepassato per la prima volta una soglia che imporrà tagli idrici senza precedenti in Arizona, Nevada e altri stati americani del sudovest. È quanto riporta il Washington Post.
Tutta l'area è attualmente confrontata ad una siccità mai vista prima, che sta portando i più grandi bacini idrici d'America ai minimi storici. Il Colorado è a livelli critici. Nonostante anni di avvertimenti, gli Stati USA che dipendono dal fiume non sono riusciti a ridurre abbastanza i loro consumi d'acqua e oggi il Governo federale ha annunciato l'attuazione di tagli drastici.
"Per evitare un crollo catastrofico del sistema fluviale del Colorado e un futuro di incertezza, è necessario ridurre l'uso dell'acqua nel bacino", ha affermato Tanya Trujillo, vicesegretario per l'acqua e la scienza presso il dipartimento degli Interni. L'amministrazione ha stabilito che, ad esempio, l'Arizona dovrà ridurre del 21% l'uso dell'acqua e il Nevada dell'8%.
Il vicesegretario agli Interni, Tommy Beaudreau, ha tuttavia spiegato che c'è ancora tempo per trovare un accordo, e che i tagli non saranno applicati prima che sia trovata un'intesa con gli Stati coinvolti.
Francia, drastiche misure contro la siccità
