The scientists evaluated how efficiently people in He′nan Province are using water by calculating their water footprint. They found that water use has been increasing in the region, with a significant jump in 2006. This growth has led to water resources being used up faster than they can be naturally replenished since 2003, causing a serious water shortage. The study also revealed that some areas, like Zhumadian and Zhoukou, are consuming lots of water but not using it efficiently, while other areas like Zhengzhou and Luoyang are doing better. To better manage water resources in He′nan, it is essential to improve how water is allocated and used across the province.
