AB  - Water is one of the important key biophysical factors determining crop 
      production. The increasing demand for crop products has placed substantial 
      pressures on water resources and then led to a series of water issues. To shed 
      light on multiple water issues in crop production, taking water footprint (WF) as 
      a measurement, a WF hotspot index system including green water scarcity (GWS), 
      blue water scarcity (BWS), water pollution level (WPL), water use efficiency 
      ratio (WUER), and water use benefit ratio (WUBR) was constructed, and an 
      empirical study was conducted to assess the WF hotspots of crop production in 
      Jilin Province. Multiple types of hotspots exhibited obvious differences in 
      spatio-temporal distribution. Hotspots of BWS and WPL were concentrated in the 
      middle and western subregions and the grades of hotspots were higher in the 
      drought and normal years. BWS and WPL had the same changing trend, showing 
      superimposed distribution in space. Hotspots of GWS and WUBR occurred in most 
      prefectures, whereas there were more WUBR hotspots and fewer GWS hotspots in the 
      humid year. The hotspots of WUER were scattered in fewer prefectures with no 
      obvious differences in different rainfall years. The water issues in the middle 
      and western subregions were various and the grades of hotspots were higher than 
      those in eastern subregion. The results of this study would contribute to 
      comprehensively understanding various water issues during crop production and 
      providing more information for sustainable agricultural water management.
