Pig megafarm expansion
Industry Expansion
In Effect
January 1, 2023
Summary
Between 2014 and 2023, Spain’s intensive pig sector expanded by 1,385 megafarm permits and 1,237 new industrial chicken and pig farm openings — the highest permit acquisition and new-farm count among EU member states over that decade — documented through official Spanish permit registers, MAPA national livestock census data, and the AGtivist/AnimaNaturalis/Carro de Combate cross-EU megafarm investigation published in June 2025. Spain’s national pig census grew by approximately 32.5% over the period while the number of pig farms declined by approximately 2.4%, indicating consolidation into fewer, higher-capacity installations; by 2023 Spain held approximately 30% of all EU pig megafarms and had become Europe’s largest pork producer and a major exporter. The expansion was concentrated in Cataluña and Aragón, facilitated by the EU’s integrated environmental authorisation framework for large installations and by integrated production contracts under which feed companies own the animals and inputs while contracted farmers invest in infrastructure. A temporary megafarm moratorium in Castilla-La Mancha ended in early 2023, leaving over 60 paused projects eligible for reactivation.
Background Context
Before the 2014–2023 expansion period, Spain already held a large export-oriented pig industry. By 2014, Spain slaughtered nearly 44 million pigs annually and exported approximately 40% of production, with a pork trade surplus of approximately €3 billion. A 2017 Food & Water Europe report described pork as approximately 37% of Spanish livestock production value and 14% of total agricultural production. A 2016 analysis noted that approximately 60% of pigs were reared under integrated production contracts. Civil society and media attention to “macrogranjas” intensified around 2020–2022, with NGOs and regional media documenting nitrate pollution, odour issues, and rural community opposition, contributing to regional moratoria in Castilla-La Mancha and other jurisdictions.

Significance
High
Between 2013 and 2023, MAPA census data document a 32.5% increase in Spain’s national pig census and a 2.4% decrease in total pig farm numbers, indicating concentration into larger operations. AGtivist’s cross-EU permit mapping (published June 2025) confirms 1,385 new megafarm permits in Spain between 2014 and 2023 and approximately 1,237 new industrial farm openings. Spain’s 3,401 pig megafarm permits represent approximately 30% of all pig megafarms in the EU+UK dataset. Pig slaughter reached approximately 58 million animals in 2021 (approximately 40% above a decade earlier) per Guardian/MAPA data. Interporc reports approximately 2.7 million tonnes exported in 2023 (approximately 57% of production). Spain’s role as Europe’s largest pork producer is confirmed in MAPA sectoral indicators for 2023. The Castilla-La Mancha moratorium ended in early 2023, potentially enabling further expansion. EU threshold revisions to lower capacity criteria for large-installation classification were enacted for the post-2023 period; practical reclassification impacts on Spanish pig farms are not fully documented in sources consulted.
Anticipated Effects
If the more than 60 paused megafarm projects in Castilla-La Mancha are approved and built, the regional pig census would increase by approximately 362,863 animals (approximately 19% of the current census).
If EU threshold revisions lowering large-installation capacity criteria are fully implemented, a larger share of Spanish pig farms would be classified as regulated installations requiring Autorizaciones Ambientales Integradas and emissions declarations.
If the pattern of consolidation continues — small farms closing while large farms grow — Spain’s pig production system would be expected to further concentrate in fewer higher-capacity installations.
Significance Rationale
The expansion establishes Spain as Europe’s largest pork producer and a major global exporter, involves tens of millions of animals annually across thousands of large installations, and accounts for approximately 30% of all EU pig megafarms.
Within The System
Key Actors
MAPA (Ministerio de Agricultura, Pesca y Alimentación) maintains the national livestock census and sectoral production data. Regional autonomous community authorities (Cataluña, Aragón, Castilla-La Mancha, and others) issue Autorizaciones Ambientales Integradas for large pig installations. Interporc (Organización Interprofesional Agroalimentaria del Porcino de Capa Blanca) provides production and export data. AGtivist, Carro de Combate, and AnimaNaturalis led the cross-EU investigation mapping megafarm permits and expansion. Named corporate operators in Castilla-La Mancha include Cefusa-El Pozo, Incarlopsa, Tello, and JISAP; comprehensive national corporate mapping is not available in sources consulted.
