In the last 50 years, pig production has increased worldwide and -before COVID-19 pandemic- it was expected to continue increasing in the following decades. Global population growth is probably the main cause of the increasing demand of pork products.
Pigs are produced in different systems including from small local farms to big technological facilities. All types of pig farms may generate the same products for consumers, but efficency, use of natural resurces and land demand differe considerably.
In a study carried out in 2019, Lassaletta et al., stated that:
The sustainability of pig production systems for the coming decades will be based not only on the expected efficiency improvements at the level of animal breeds, but also on four additional pillars:
In 2020, the TOP-10 pig producing countries are led by China, followed by Europe (EU-27) and Unitated States. However, according to the USDA report, global pork production is expected to fall by 7% due to COVID-19 and African Swine Fever outbreaks. Ms Rusk said that:
It is likely the outbreak of COVID-19 has only slowed progress in China and strong export demand from Asian countries has provided producers with the incentive to expand herds. However, this is not enough to compensate for the decline expected in China and other nations affected by ASF
