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 (Autorizaciones Ambientales Integradas), MAPA national livestock census data, and the AGtivist/AnimaNaturalis/Carro de Combate cross-EU megafarm investigation published in June 2025. As of 2023, Spain held 3,963 valid permits for intensive poultry and pig installations (3,401 pig, 562 poultry), representing approximately 16% of all such farms in the EU and UK dataset and approximately 30% of EU pig megafarms — more than double Denmark’s count. The national pig census grew by approximately 32.5% between 2013 and 2023 while the total number of pig farms declined by approximately 2.4%, indicating consolidation into fewer but higher-capacity installations. Pig slaughter reached approximately 58 million animals in 2021, approximately 40% above the level a decade earlier. Spain became Europe’s largest pork producer and, by 2023, Interporc data indicate approximately 2.7 million tonnes of pork products were exported — approximately 57% of 4.88 million tonnes produced that year.
The expansion was concentrated in specific autonomous communities: approximately half of Spain’s pig population of roughly 33 million animals is distributed across Cataluña and Aragón. The Castilla-La Mancha region operated a temporary moratorium on new megafarm projects that ended in early 2023, leaving over 60 paused projects eligible for reactivation, with a documented potential expansion of approximately 362,863 additional pigs (approximately 19% of the region’s current census) if all pending projects proceed. The expansion was facilitated by the EU’s integrated environmental authorisation framework (AAI), which classifies intensive pig installations above specified capacity thresholds (≥2,000 pigs over 30 kg or ≥750 breeding sows) as large installations requiring environmental permits, with regional autonomous community authorities issuing those permits. Approximately 60% of Spanish pig production operates under integrated contracts in which feed companies own the animals and inputs while contracted farmers invest in infrastructure — a model associated with capital-intensive large facilities. Named pig sector operators in Castilla-La Mancha include Cefusa-El Pozo, Incarlopsa, Tello, and JISAP, though comprehensive national corporate mapping is not available in sources consulted.
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.

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
Assigned Expands Exploitation (impact direction) because the 2014–2023 period produced documented increases in: megafarm permits (1,385 new), new industrial farm openings (1,237), national pig census (approximately +32.5%), pig slaughter throughput (approximately 58 million in 2021, approximately 40% above a decade earlier), and export volumes (approximately 2.7 million tonnes in 2023). These are documented operational expansions across multiple quantified metrics confirmed by official MAPA census data, Interporc production statistics, and independent investigative mapping.
Assigned Changes Scale (impact type) because the primary mechanism is the expansion of high-capacity pig installations through new permits and farm openings, directly increasing animal numbers and production volumes within Spain’s intensive pig exploitation system.
Assigned High significance because 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.
The scale change is sustained: pig census growth and megafarm consolidation persisted beyond two years without documented contraction to prior levels as of 2025.
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.
