Description
Summary:[Display omitted] •Urbanisation was a core driver of staple crop WFSS in water scarce provinces.•Population and social urbanisation enhanced China’s staple crop WFSS.•Economic and spatial urbanisation reduced crop WFSS.•This work challenged the conventionally urbanisation-water relationship. Rapid urbanisation in developing countries has exerted ever-increasing pressure on food and water resource systems. Existing studies mostly focus on impacts of population urbanisation on agricultural water use, disregarding the multidimensional characteristics of urbanisation. Accounting for four dimensions of urbanisation: population, economy, spatial distribution, and society, we assessed the impact of multidimensional urbanisation on the water footprint self-sufficiency rate (WFSS) of three staple crops, that is, the ratio of the water footprint (WF) of crop production to the WF of crop-related consumption, through the case for China over 2000–2017. The socio-economic driving factors and spatial heterogeneity of crop WFSS were further tested. Results show that
