Case 3. The North China harvest is just an unsustainable appearance


Some foreign experts described the North China Grain Granary as a “food bubble” and predicted that such long-term over-exploitation must be unsustainable. Although there is a good harvest in front of it, the actual fact behind it is—the North China Plain annual ultra-mining groundwater of about 10 billion cubic meters is more than 60% of the groundwater over-exploitation in the plains of the country. Among them, the over-exploitation of groundwater in Hebei Province is the most serious. About 6 billion cubic meters. How did the groundwater come from? The North China Plain has already overcharged more than 100 billion cubic meters of groundwater. If it relies on natural circulation to supplement these groundwaters, it will take at least 10,000 years.


In response, China has promoted adaptation to tackling climate change. Since 2014, the government has implemented climate change addressing adaptation from agriculture, water resources, forestry and other ecosystems, coastal zones and related sea areas, and meteorological areas around the National Climate Change Adaptation Strategy. Work and positive progress have been making. In the agricultural sector, accelerate the transformation of agricultural production methods and modernization. Since 2014, the Ministry of Agriculture and the China Meteorological Administration have formulated a number of work plans, such as the “Responding to the El Ni?o Phenomenon to Achieve Disaster Relief and Harvest”, to implement defense measures early. Promote conservation tillage. In 2014, the Ministry of Agriculture invested 30 million yuan to carry out conservation tillage in several regions. Continue to carry out agricultural infrastructure construction. Strengthen soil fertility improvement. Continue to promote water conservation in the northeast, water saving in the northwest, water-saving mining in North China, the “five small water conservancy” project in the southwest, and water-saving and emission reduction projects in the south.
