Reprint of “Quantifying yield gaps in rainfed cropping systems: A case study of wheat in Australia”

► A new framework proposed for assessing and mapping yield gaps in data rich regions. ► Rainfed yield potential mapped in space and time in Australia's Wimmera region. ► Ground testing confirms yield gap assessments in the Wimmera case study. ► Achieving 80% of yield potential in the Wimmera would boost production by 51%. ► Substantiates claims that reducing yield gaps is a key global food security pathway.
