Intensive Farming Threatens Biodiversity and Rural Livelihoods in Europe

February 4, 2025

Intensive farming practices are causing significant harm to protected areas, biodiversity, and local communities across Europe. The detrimental impact of such agricultural methods is becoming increasingly evident. From the ecosystems within the European Union’s Natura 2000 network to the livelihoods of rural populations, the adverse effects of industrialized farming continue to mount. This article delves into specific incidents, underlying causes, and explores potential solutions to mitigate the adverse effects of this agricultural model.

The story begins with a personal account from Manuel Ferreira, a resident of Figueiro da Serra, Portugal, who witnessed the devastation caused by massive wildfires in 2017 and 2022. These fires, believed to have originated from extensive eucalyptus plantations, were neither contained nor mitigated effectively by local authorities. The eucalyptus species, a non-native plant, covers more than a quarter of Portugal’s forests and significantly contributes to the cause and spread of wildfires. This phenomenon isn’t just restricted to the regions within Portugal—it spans across Europe, posing great risks to biodiversity, protected areas, and rural livelihoods.

Impact on Biodiversity and Protected Areas

Intensive farming’s encroachment into protected zones, such as the Natura 2000 network, exemplifies a significant threat to biodiversity conservation efforts. This network, including over 27,000 protected areas, represents Europe’s overarching effort to preserve its natural heritage and ensure sustainable environments. However, such farming practices lead to habitat destruction, fragmented landscapes, and increased use of harmful chemicals. According to the European Environment Agency’s report on the State of Nature in the EU, about 75% of habitats are in poor or bad condition, attributing much of this degradation to agricultural activities.

The widespread planting of eucalyptus in Portugal and the extensive abstraction of water for berry polytunnels affecting the Doñana Biological Station in Spain serve as specific examples of how industrialized agriculture undermines conservation goals. These practices threaten the flora and fauna within these protected spaces and disrupt the ecological balance, resulting in long-term environmental repercussions. For instance, the Doñana Natural Park, a vital refuge for numerous bird species, faces potential ecological collapse due to water extraction for agricultural use. This depletion of water resources poses significant threats not only to biodiversity but to broader ecological stability as well.

Socio-Economic Impact on Rural Communities

The transition from traditional farming to large-scale, intensive operations has paved the way for considerable socio-economic shifts within rural communities. Journalist and activist Javier Guzmán from Justicia Alimentaria sheds light on the concept of “salarisation” of farming, highlighting the replacement of smallholder farmers with migrant laborers who work under precarious conditions. This system of circular migration often involves temporary employment arrangements that exploit workers without regard for their long-term welfare, creating an environment fraught with instability and exploitation.

The domination of large agribusinesses is driving these changes as they accumulate land and water resources, consequently marginalizing local farming communities. This trend does more than just affect the livelihoods of smallholder farmers; it erodes the social fabric of rural areas, triggering depopulation and the loss of traditional agricultural knowledge and practices. Such shifts have led to the degradation of community bonds and threatened the continuity of historical, region-specific farming techniques that once thrived, now making way for extensive monoculture farming. These socio-economic impacts, shaped by intensive farming, hold far-reaching implications for community coherence and sustainability.

Environmental Hazards of Monoculture Plantations

Research has consistently shown that monoculture plantations of species like eucalyptus and pine significantly heighten fire hazards in Portugal and beyond. A study conducted by researchers from the Polytechnic Institute of Leiria and the University of Minho has revealed that eucalyptus trees are disproportionately involved in wildfire incidents compared to native species like Holm oaks. Eucalyptus and pine trees have particularly high flammability and facilitate rapid fire spread, exacerbating the risk and impact of wildfires. This leads to severe environmental and property damage, underscoring the need for reconsidering plantation practices.

The repercussions of such fires extend beyond the immediate destruction of local flora and fauna; they also place human settlements in jeopardy. The fires devastate entire ecosystems, resulting in loss of biodiversity and long-term ecological damage while putting communities at risk. The dependency on monocultures for economic purposes must be balanced with the need for sustainable and fire-resistant forestry practices. A holistic approach, prioritizing native species and forest management, can mitigate these fire risks and contribute to healthier ecosystems.

Strain on Water Resources

The pressure exerted on natural water resources by intensive farming is alarming and poses a massive threat to both agriculture and ecosystems. The Doñana Natural Park crisis in Spain illustrates how water abstraction for large-scale agricultural use can lead to severe ecological imbalances. Intensive farming practices for the berry industry, particularly those involving polytunnels, have led to the depletion of aquifers, causing marshes—the lifeblood for migrating birds—to dry up. This has severely disrupted the region’s delicate ecological balance.

As emphasized by Miguel de Felipe from the Doñana Biological Station, such water extraction leads to significant disruption in indigenous ecosystems, which ultimately results in the decline of bird species dependent on these marshes. The broader implications extend beyond biodiversity; the unsustainable use of water resources in intensive farming poses long-term risks to water availability and security. The local communities are likely to face water shortages, further intertwining the fates of agricultural sustainability and human consumption in precarious ways.

A Look at Sustainable Agriculture Models

Despite the challenges posed by intensive farming, there are positive examples where agriculture harmoniously coexists with conservation efforts. France’s Loire-Anjou-Touraine natural park stands out as a successful case where sustainable agricultural practices support local biodiversity. Here, the nesting of the Montagu’s harrier within agricultural landscapes is a testimony to thoughtfully managed eco-friendly farming practices. Farmers, collaborating closely with organizations like the League for the Protection of Birds, ensure the survival of these birds while promoting and adhering to sustainable farming models.

These practices highlight that with deliberate and thoughtful management, agriculture and biodiversity conservation can indeed be mutually beneficial. Such symbiotic relationships offer valuable insights and a blueprint for integrating environmental stewardship into agricultural endeavors. These sustainable approaches ensure the balance between food production and the preservation of natural habitats, proving that economic activities need not displace environmental integrity.

Solution and Future Outlook

Reflecting on the dilemmas posed, potential solutions and future directions stress the enactment of regulatory measures and community-led conservation efforts to counter the adverse effects of intensive farming. The implementation of the Nature Restoration Law scheduled for August 2024 stands as a significant legislative step requiring EU member states to restore 20% of degraded habitats by 2030, focusing primarily on areas within the Natura 2000 network. This legislation encourages the transition towards agroecological models, aiming to repair the damage caused by intensive farming.

An inspiring example comes from the Serra da Lousa region, where local communities, guided by the Veredas da Estrela association, embrace traditional sustainable practices. These communities have reclaimed abandoned lands for cultivation, a move aimed at reducing fire risks while fostering a resilient and diverse ecosystem. This initiative reflects a broader sentiment advocating a return to traditional agricultural models that not only align with environmental protection but also support community sustenance.

Conclusion

The unchecked expansion of intensive farming practices, driven by the singular pursuit of maximizing profits, posed substantial threats to protected areas, biodiversity, and rural communities across Europe. From the devastation of forests in Portugal to the water crises in Spain, the adverse effects were pronounced, often intertwining with socio-economic struggles of rural populations. Yet, the exploration of traditional and sustainable agricultural practices provided a hopeful glimpse into the future. Empowered by legislative support, these eco-friendly models held the promise of mitigating environmental degradation and fostering a harmonious balance between agriculture and conservation. Through their adoption, Europe could strive towards an equitable and sustainable food system for future generations.
