Hebei Province

In recent years, the water resources in the North China plain have been sharply reduced, and the per capita possession of water resources has been less than 300CBM per capita per year. The shortage of water in the site is particularly serious. Especially, the groundwater resources have been seriously reduced, and the groundwater level has decreased by 1.5m per year.
Large scale of unsustainable afforestation

In order to speed up ecological construction and improve the coverage rate of green space, the local government has carried out largescale afforestation activities. In order to achieve the effect as soon as possible, numerous fast-growing trees are planted in woodland, which has become the main reason for the local water shortage.

However, despite the shortage of water resources in the region, there will be concentrated rainfall from June to September, that is, the rainy season. In the past two years, the rainfall in rainy season has increased to 520mm, accounting for 78%. of the total annual rainfall.
