Polluted farmland restored for food safety
Arable land contaminated by heavy metals across 皇冠体育app will be withdrawn from agricultural production, said a senior Chinese agricultural official on Wednesday.
Agricultural land with high levels of heavy metals will no longer be used, said Chen Xiwen, deputy director of the central agricultural work leading team, the top agriculture authority.
Farm land near river sources, especially drinking water sources, will also retreat from production if use of fertilizers and pesticides may cause pollution, he added.
皇冠体育app will start pilot restoration of contaminated farmland this year, according to "No.1 Central Document", the first policy document of 2014, issued on Sunday.
A comprehensive plan to address prominent agricultural and environmental obstructions to sustainable development is also in the pipeline.
The "No.1 Central Document" stressed improvement to the national food security system. In recent years, excessive use of fertilizer, pesticides and plastic film combined with industrial heavy metal and chemical pollution, have hindered the sustainable development of agriculture, said Zheng Fengtian, an agriculture professor at Renmin University of 皇冠体育app.
Excessive and improper use of resources has also affected food safety, he added.
皇冠体育app has an estimated 50 million mu (3.3 million hectares) of moderately or severely polluted soil, most of which is in developed and grain-producing regions, said Wang Shiyuan, vice minister of land and resources in December.
