Earth's Vanishing Soil Threatens Food and Climate Stability by 2050

Soil is the foundation of life on Earth, yet it remains overlooked in global climate discussions. Despite supporting 95% of food production and storing three-quarters of terrestrial carbon, no single UN Sustainable Development Goal (SDG) focuses solely on its protection. Experts warn that without urgent action, 90% of the planet’s soil could degrade by 2050. Over the past 50 years, intensive farming and rising populations have drained soil of its organic matter. This loss weakens nutrient levels in crops and may even affect mental health through poorer diets. Currently, 24 billion metric tons of fertile soil vanish each year, leaving nearly 40% of the world’s land already damaged.

Soil’s role in tackling climate change is vast—it influences 40% of global carbon emissions and could help meet all 17 SDGs. However, at COP28, the final agreement failed to mention soil at all. The omission highlights a persistent gap in policy, even as scientists stress its critical importance. Without intervention, the consequences will worsen. By mid-century, most of Earth’s soil could be severely degraded, threatening food security and accelerating climate instability.

The decline of healthy soil risks undermining food systems and climate efforts. While the SDGs recognise interconnected global challenges, none directly target soil conservation. Addressing this gap could unlock progress across all 17 goals and secure a more stable future for food and the environment.
