RP retention by dams in individual watersheds in 1970 (A), 2000 (B), and 2030 under the GO scenario (C). The 2030 RP retentions assume that all dams currently planned or under construction will be completed by 2030 (2). The GO scenario predicts the highest global river P load by 2030 and, hence, yields the largest relative changes in P retention.
