Environmental Degradation and Deforestation in Spain

1. The Destruction of Forest Cover

Economic development in Spain between 1960 and 1973 occurred at the expense of large industrial concentrations and the abandonment of rural areas. This marginalized certain regions, resulting in severe environmental degradation. Today, there is significant civic and political awareness regarding environmental issues, leading to the establishment of the Ministry of the Environment in 1996.

Major Environmental Challenges

The most serious problems are not solely due to human action, but include:

• Process of soil erosion and desertification.
• Contamination of groundwater, surface water, and marine environments.
• Unprevented natural disaster risks.
• Soil contamination or depletion due to overexploitation and toxic dumping.
• Soil salinization.
• Partitioning of land for public works, creating a barrier effect detrimental to wildlife.
• Industrial invasion of agricultural and urban land.
• Destruction of ecologically valuable territories caused by land speculation.
• Forest fires.
• Nuclear plants and the storage of generated waste, including research centers and hospitals.
• Disposal of solid urban and nuclear waste.
• Deterioration of coastlines due to housing developments or tourist facilities.

Deforestation and Forest Fires

The destruction of vegetation cover is primarily caused by agricultural occupation, land reclamation, and forest fires.

Felling and Fires

Fires are often caused by summer heat. While the Atlantic deciduous forest offers more fuel, the dry, dense vegetation of the Iberian Peninsula—characterized by bushes, clear forests, and abundant pine—is more susceptible to fires due to low humidity, poor aeration, and high temperatures. Spain records the highest vegetation losses in the EU due to fires, with 96% estimated to be human-caused, concentrated in Galicia, the mountains of Leon, the Cantabrian range, and the Mediterranean area.

Reforestation Alternatives

To address forest loss, a policy of afforestation has been implemented over the last few decades, covering approximately 2.5 million hectares. Most current forests consist of species introduced by humans, with the state involving itself in repopulation efforts, even on private land.

2. Issues Arising from Agricultural Usage

Overgrazing and inappropriate farming practices emphasize soil erosion. Issues include failing to allow the ground to rest sufficiently and the abuse of chemical fertilizers and pesticides on steep slopes without protective measures.

Chemical Abuse of Fertilizers

These fertilizers remain in the soil and cause diffuse pollution in groundwater. This affects the hydrological cycle and enters the human food chain when absorbed by fruits and vegetables.
