The Catalan government is undertaking emergency works across several streets in Sant Joan Despí to establish a control perimeter. This aims to manage the region’s burgeoning wild boar population and halt the potential spread of African Swine Fever (ASF).

The Generalitat de Catalunya initiated this construction as a significant preventive measure, designed to physically block wild boar movement through this key area of Baix Llobregat. By creating a contained zone, authorities hope to prevent the animals from carrying the highly contagious virus into new territories, thereby protecting both the local ecosystem and the vital agricultural sector.
A Pre-emptive Strike Against a Pervasive Threat
African Swine Fever is a severe viral disease that affects domestic pigs and wild boars, with a very high mortality rate. While it poses no health risk to humans, an outbreak could be devastating for Catalonia’s pork industry. This move in Sant Joan Despí is part of a broader, increasingly urgent strategy to get ahead of the disease, which has put authorities on high alert across Europe.
Catalonia faces a dramatic overpopulation of wild boars (Sus scrofa). The government’s Department of Climate Action, Food and Rural Agenda recently estimated the population at between 125,000 and 180,000 animals. To mitigate their impact on agriculture, road safety, and urban areas, the Catalan government intends to significantly reduce the population, with some proposals aiming to cut numbers by as much as half.
Emergency Measures on the Ground
The Ajuntament de Sant Joan Despí confirms these works will create a definitive barrier. Physical containment is one of the most effective methods to manage animal movement in a specific area. This strategy reflects a growing reliance on infrastructural solutions for public safety and management, not unlike how Barcelona uses hundreds of temporary barriers for large-scale events like Sant Jordi to control crowds.
Sant Joan Despí’s location makes it a strategic point for such a perimeter. Nestled in the Barcelona metropolitan area, it sits at the intersection of urban development and the natural habitats from which the boars emerge, often foraging for food in parks, residential streets, and rubbish bins.
A Region-Wide Challenge
These measures are not isolated. This action follows restrictions implemented in numerous other municipalities across Barcelona province due to the swine fever threat. Officials stress this will be a long-term effort; a 3Cat report notes the operation to eradicate boars and fight the disease will not be over in a matter of days (‘No seran quatre dies’).
While physical barriers are a key tool, researchers and wildlife management experts are also evaluating a range of other methods, including enhanced hunting protocols and live capture, to bring the population under control. For residents of Sant Joan Despí and other affected towns, the sight of construction is a tangible sign of a complex, ongoing battle between urban life and wild nature, supercharged by the invisible threat of animal disease.
