Sparrow eradication
Sparrows were treated as net agricultural enemies whose mass eradication would increase grain production.

Current understanding
Current understanding
Sparrows can consume grain, but they also eat insects and participate in food webs. Large-scale predator removal can trigger ecological effects that make simple “pest equals net harm” assumptions fail.
Institutional episode
People's Republic of China
During the Four Pests campaign, a February 1958 directive from the CCP Central Committee and State Council explicitly classified sparrows as major enemies that damaged grain and obstructed production. Mass killing sharply reduced sparrow populations. Historical and ecological reviews describe subsequent insect outbreaks, ecological disruption, and poor harvest effects; by June 1959 sparrows had been removed from the official Four Pests list. This card does not attribute the Great Famine to the sparrow campaign alone.
Institutions
- Central Committee of the Communist Party of China
- State Council of the People's Republic of China
Documented consequences
- Wildlife eradication
- Agricultural policy
- Ecological disruption
Institutional machinery
The national institutional proposition is unusually explicit. On 12 February 1958, the CCP Central Committee and State Council jointly issued the directive 关于除四害讲卫生的指示, describing rats and sparrows as major enemies that damaged grain and obstructed production. Mass implementation then ran through the wider Four Pests and patriotic-health mobilization apparatus; those provincial and local implementation networks are described as machinery rather than listed as if they were single institutions.
