Caption
Belief in the claim that irrigation agriculture is responsible for 70% of all freshwater withdrawals, as a function of time in polar coordinates. The size of the nodes (documents) correspond to their degree; that is, the number of incoming edges (citations). Blue nodes (“citation backup”) denote documents that make the claim and support the claim with a citation. Green nodes (“modeling”) represent documents that produce original data supporting the claim through a modeling or statistical exercise. Orange nodes (“no citation”) are documents that make the claim but do not produce original data nor cite any study to support the claim. Red nodes (“no claim”) are documents that are cited to support the claim but do not actually make the claim. Grey nodes (“NA”) represent documents that are cited as making the claim but that we have been unable to access.
