From: Climate adaptation through rice northward expansion aggravated groundwater overexploitation in Northeast China

Fig. 7

The red lines of subfigures are groundwater elevations based on field observations; green lines are the ratio of rice areas that are the sum of a 5 km buffer of wells to the buffer area. ** and * mean Pearson correlation coefficients are significant at the level of 0.05 and 0.1.
