Protecting Europe's land and soil resources is fundamental for a sustainable future
Land and soil underpin life on our planet. The way we currently use these vital and finite resources in Europe is not sustainable. Human activities — growing cities and infrastructure networks, intensive agriculture, pollutants and greenhouse gases released to the environment — transform Europe’s landscapes and exert increasing pressure on land and soil. The European Environment Agency’s (EEA) Signals 2019, published today, looks at a series of issues linked to land and soil, including links to climate change, agriculture, soil biodiversity, contamination and governance, and stresses why we need to manage them sustainably.

"Land governance is complex but we all benefit from the services that healthy land and soil provide — be it nutritious food or clean water, protection against diseases or construction materials. To ensure that future generations continue to benefit from these services, we need to take decisive action today. The responsibility to protect these vital resources lies with us all — from consumers to farmers, and from local to European and global policymakers. This can only be achieved by acting together today towards a common goal." Hans Bruyninckx, EEA Executive Director

The EEA Signals 2019 ‘Land and soil in Europe’ explains key pressures — such as urban sprawl, contamination, intensive use of agricultural land, landscape fragmentation — impacting Europe’s land and soil. Today, artificial surfaces (buildings, roads, urban facilities) cover less than 5 % of the wider EEA territory and continue to grow despite slowing down in recent years. Almost three quarters of Europeans live in urban areas and continued urban sprawl is often threatening productive land used for farming as well as forests and other areas home to wildlife and vital ecosystems.
The report underlines that we need to preserve and protect these key resources better. For example, the way we build and connect cities should prioritise ‘land recycling’, which consists of re-using and re-purposing existing urban areas such as old industrial sites and avoid new land to be covered by concrete and asphalt. Europe’s urban population is projected to grow by 30 million by 2050. Given these projections, compact cities with well-connected mobility options will need to play a key role to provide better quality of urban life with fewer impacts on the environment.
Similarly, pressure from economic activities, including agriculture, can adversely affect the health of land and soils. Plant protection products containing harmful chemicals can boost yields in the short-term but risk undermining soil productivity in the long-term. Europe’s agriculture sector relies on healthy soils, which can only be ensured through a comprehensive set of measures involving a combination of agricultural practices (e.g. precision farming, crop diversification, etc.), rural and agricultural communities (e.g. tackling land abandonment), as well as retailers and consumers (e.g. reducing food waste).
Healthy and resilient soil ecosystems are also essential to help mitigate and adapt to climate change. Europe’s soils and land store massive amounts of carbon. On the one hand, warmer temperatures can melt permafrost and release some of this carbon into the atmosphere, contributing to climate change. On the other hand, a sustainable use of our soils can help keep this carbon stored in the ground. Natural areas or soils not covered by artificial surfaces or compacted by heavy machinery can help absorb excess rain in case of intense precipitation or act as a water storage in times of drought.
The report also addresses the need to protect land ecosystems better, and to ensure that natural areas, home to wildlife, are better connected to each other to enable species to move and migrate. This requires an extensive network of green infrastructure, connecting natural areas.
New tools, like the European Union’s Earth observation and monitoring programme, Copernicus, which is revolutionising the way we understand and plan for the more sustainable use of our valuable land and soil resources.
A healthy and sustainable use of our land and soil resources will help the Europe Union achieve many of its policy targets ranging from climate change mitigation to halting biodiversity loss, as well as Sustainable Development Goals.
The EEA Signals report is an annual, easy-to-read publication, consisting of a series of short articles, that looks at key issues related to the environment and climate. Recent EEA Signals reports have looked at water (2018) energy (2017), transport (2016), and climate change (2015).
