Abstract
In 2015, the Chinese government banned livestock production in some regions (called non-livestock production regions, NLPRs) to control surface water pollution near vulnerable water bodies. In total, 90,000 NLPRs had been established by 2017, covering a land area of 0.82 million km2 and shutting down 0.26 million pig farms1. As a consequence, the number of slaughtered pigs decreased by 46 million head yr–1 between 2014 and 2017. The NLPRs policy is globally unprecedented in terms of the geographical area and number of farms affected, as well as its implementation speed. The NLPRs policy has reduced pork self-sufficiency in some provinces by up to 40% (ref. 2). However, it is unclear which farms and regions may take over the market share.
