In the case study of Tangshan city, Hebei Province, China, this paper analyzes temporal change of blue agricultural water footprint (WF) during 1991–2016 and discusses the applicability of different climate change models during 2017–2050. Results show effective rainfall, wind speed and maximum temperature are leading factors influencing the blue agricultural WF. Relative error analysis indicates that the HadGEM2-ES model is the most applicable for climate change projections in the period of 2017–2050. Agricultural blue WF is about 1.8 billion m 3 in RCP2.6, RCP4.5 and RCP8.5 emission scenarios which is almost the same equal to the average value during 1991–2016.
