Soil Atlas 2024

Healthy soils are a basic requirement for producing nutritious food, preserving biodiversity and adapting to climate change. But the condition of the soils is poor, with more than a third of the world's agricultural land being considered degraded. In the European Union, more than 60 percent of soils are now damaged - caused, among other factors, by industrial agriculture and the effects of the climate crisis such as droughts. This is outlined in the Soil Atlas 2024, published today by the Heinrich-Böll-Stiftung and TMG – Think Tank for Sustainability.

Funding climate protection through carbon certificates for soil may seem beneficial at first. However, a greater focus on soil health and supporting farmers in adopting sustainable practices would be far more effective in practice.

In recent years, research interest in biochar has gained significant attention in mainstream discourse. The sustainable alternative to synthetic fertilisers offers triple benefits: enhanced soil health, improved livelihoods, and climate protection. 

Soil is the foundation of life on Earth. Its beauty and complexity as a living ecosystem are vast, and its functions are integral to our lives. For example, 95 percent of global food production depends on healthy soils, making access to fertile soil essential in the fight against hunger. Soils are also a crucial ally in adapting to climate change, as they help buffer the effects of droughts and floods. 

Soil degradation is a major but largely neglected global problem that threatens agricultural productivity, food security, and ecosystem health. Around one-third of soils worldwide are degraded, with over 40 percent located in Africa.

While desertification is a problem most commonly associated with Africa or Asia, it is not limited to these regions. Intensive agriculture and the climate crisis have also led to severe soil degradation and desertification in Europe. And not just in southern Europe: even countries with temperate and humid climates, such as Hungary and Bulgaria, are affected.

As the climate crisis intensifies around the world, severe storms and flooding are becoming more frequent. Healthy soils can help buffer the effects of extreme weather. For that reason, soil protection is more important than ever. Yet, it is still neglected.

Overuse of artificial fertiliser is bad for soils and, in the case of nitrogen fertilisers, for the climate as well. Moreover, pesticides deplete the soil of beneficial organisms. Yet these products earn big money for big companies, which influence governments, often blocking policy changes needed to protect people and the environment.

Synthetic fertilisers harm the climate, but industrial farming relies heavily on them. Additionally, higher fertiliser prices have pushed up prices for food commodities. African countries, where food crises intersect with debt crises, are hit especially hard.

Phosphorus is bioessential, meaning that all living organisms require it. Yet, despite its presence in soils, it is a relatively rare element on Earth and is not always found in a form that plants can absorb. The fertiliser industry produces easily soluble phosphorus but depends on a finite, non-substitutable resource: phosphate rock.

The production of synthetic nitrogen fertiliser using renewable energy instead of fossil fuels can reduce greenhouse gas emissions upstream. But it does not solve the problems associated with excessive use of synthetic fertilisers, such as diminished soil health, biodiversity loss, on-field greenhouse gas emissions, nitrate pollution, and overdependency on external inputs. 

Land has been heralded as a crisis-proof investment around the world. However, these deals often make money for the wealthy few, while pushing local people off their land and into poverty. Countries like Germany, Singapore, and the United States are complicit in such land grabs.

The phenomenon of large companies and investors buying up vast tracts of arable land in the Global South has long been seen as a problem. In Germany, too, this kind of land grabbing is on the rise, with small and medium-sized farms pushed out. A reorientation that prioritises the common good is needed.

Soil plays a major role in protecting the environment. It serves as carbon reservoirs, the plots into which trees are planted, and a steward for producing climate-neutral fuels. But land-intensive climate action can give rise to conflicts and erode people’s rights. Even so, there is yet to be a resolution for this mounting global challenge in sight.

The world’s soils store more carbon than its forests, and this storage capacity is increasingly discussed as a contributor to climate protection. Tradable carbon credits were designed to incentivise the build-up or retention of carbon in the soil. However, they may in fact undermine efforts to reduce emissions.

Equitable access to land and fertile soil is fundamental to realising human rights, such as the right to food. Although numerous United Nations declarations on land rights have been ratified by national governments, deadly land conflicts persist throughout the world.

Secure land access is essential for long-term soil protection because it enables land users to implement practices that enhance soil health and maintain its productivity over time. However, in many African countries, women’s land rights remain precarious, creating significant barriers to investing in sustainable soil management.

Protection measures for climate, water, and biodiversity have been enshrined in EU law – in some cases, for decades. But a comprehensive legal framework for soil protection is still lacking. Previous attempts to create one have been torpedoed, while most existing policies are toothless.

Agroecology is a response to an industrial model of agriculture that exploits people and damages soils. In Brazil, agroecology is making significant breakthroughs in social and environmental terms. But one thing is already clear: government policy is needed to promote agroecology and confront the agroindustrial model.

Land degradation has numerous invisible costs – environmental, health, social, and economic. True Cost Accounting renders these costs visible, offering a clearer picture of the impact of land degradation.

Modern farming techniques were introduced to India during the Green Revolution of the 1960s to meet the needs of a rapidly growing population. However, the overuse of chemical fertilisers and pesticides, alongside the cultivation in monocultures, severely damaged soil health. In response, many farmers are moving back to alternative soil management practices. Political support for this transition is growing, but requires more flame to ignite change.

The Sahara Desert is expanding, thereby threatening millions of people’s lives and livelihoods. While many large-scale initiatives have been launched to combat desertification, most lack secure funding. Bottom-up techniques, implemented by local farmers, show how Indigenous knowledge can drive restoration.
