A food system revolution for China in the post-pandemic world

The COVID-19 pandemic is worsening food shortages in food deficit countries, such as China, which rely on import for domestic food consumption. We argue that fundamental revolution in China’s livestock system can meet about 50% of its consumption of livestock products and thereby reduce the country’s reliance on imports. Three food system revolutions that can greatly reduce China’s reliance on imports are technically and economically feasible, and generate high eco-system benefits: (1) organic or inorganic based microbial feed protein production to substitute imported feed protein, (2) vegetation greening and fodder production through grassland restoration to reduce import of ruminant animal products, and (3) insect protein based fish-plant production and offshore marine restoration to replace red meat consumption and increase recycling of manure. Together these revolutions can accelerate progress towards multiple Sustainable Development Goals in exporting countries.
