Caveats

"Major" reflects WRI's criteria: basin population, economic dependency, biodiversity, and transboundary significance. Other lists (by length, discharge, basin area) differ. The Amazon (largest discharge), Yenisey (5th longest), and Ob-Irtysh are notable omissions. Many rivers cross borders—cooperative governance is essential.
