Tre persone su dieci (2,1 miliardi) nel 2015 non avevano accesso all'acqua potabile e 4,5 miliardi di persone, pari a sei su dieci, non disponevano di servizi igienici sicuri. Lo rileva l'ultimo rapporto dell'UNESCO sullo sviluppo idrico globale pubblicato martedì in vista della Giornata mondiale dell'acqua indetta dall'ONU per il 22 marzo.
I rifugiati sono una categoria fortemente vulnerabile e il loro numero è destinato ad aumentare a causa dei cambiamenti climatici. Nel 2017, conflitti e persecuzioni hanno costretto 68,5 milioni di persone a fuggire dalle loro case, mentre 25,3 milioni di persone in media all'anno sono costrette a migrare a causa di disastri naturali, il doppio rispetto ai primi anni Settanta.
Acqua pulita e servizi igienico sanitari sono obbiettivi dell'Agenda 2030 per lo Sviluppo Sostenibile, il programma d'azione per le persone, il pianeta e la prosperità sottoscritto nel settembre 2015 dai Governi dei 193 Paesi membri dell'ONU.
