Data la necessità di ulteriori studi sulla trasposizione del fiume São Francisco e sui suoi potenziali effetti sul cambiamento delle dinamiche dei bacini riceventi, questo studio è stato condotto nell’area corrispondente al tratto medio del bacino di Ipojuca, nello Stato di Pernambuco. Il lavoro utilizza tecniche di telerilevamento e di elaborazione delle immagini per analizzare la vegetazione intorno al bacino e cerca di stimare il grado di vulnerabilità ai cambiamenti climatici e il grado di stress idrologico nel suo tratto centrale. I risultati mostrano che il bacino è altamente vulnerabile ai cambiamenti climatici, con un elevato stress idrologico e alti livelli di stress idrico in vaste aree della sezione centrale del bacino di Ipojuca. I risultati dell’elevato stress idrico del bacino corroborano gli studi che già avvertivano che molte delle aree più aride del Nord-Est avrebbero dovuto affrontare uno stress idrico che sarebbe peggiorato nel corso di questo secolo. Alla luce di ciò, concludiamo che è necessario trasporre le acque del fiume São Francisco nel bacino di Ipojuca, ma discutiamo i benefici sociali e i potenziali impatti ambientali che questa trasposizione porterà all’area in questione.
