Global irrigation contribution to wheat and maize yield

HIGHLIGHTS

• who: Xuhui Wang from the Peking University, Beijing, China have published the research work: Global irrigation contribution to wheat and maize yield, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS of 13/07/2019
• what: The authors explore the balance between irrigation demands to close the yield gaps and available river discharge for irrigation, showing that a large fraction of contemporary rainfed agriculture could not rely on irrigation to achieve yield gap closure and mitigate climate change impacts without hydrological engineering efforts like cross-basin water transfer.
• how: With revised ΔY and its uncertainty . . .
