The hot dry weather in the south and east is causing drought to linger in both regions. Xinhua reports low reservoir levels in Guangdong where rainfall in the first ten months of this year has been 14% below normal. Water levels are also low in neighboring Jiangxi to the east after a month without rain and in southeastern Fujian the situation seems worse with reservoirs dry and more than 110,000 people left short of water. Meanwhile in Shandong, on the eastern edge of the arid North China Plain, 330,000 hectares of cropland are reported drought-stricken with no break to the dry spell in sight.
The bigger picture is that the slow desertification of the North China Plain is not being reversed quickly enough. Artificial rain-making is only ever an emergency response. The grand plan to divert the waters of three rivers to the region will take years to come to fruition, and may have unintended environmental consequences of its own, just switching part of the problem elsewhere. Demand for water has to be tackled as well as supply. That not only means switching to low-water irrigation methods on farms across China’s wheat-growing heartland but also stepping up conservation efforts in the big cities at the eastern end of the plain. It is the rapid growth of places like Beijing and Tianjin that have been a primary reason that the water table has fallen so far and so fast over the past 20 years. Producing water-conservation technology would also make useful work for idle hands in the export factories of the south.
