    The world's largest treasure lies beneath our feet in the form of soil organic matter, which is crucial for plant growth by storing nutrients and water. It plays a significant role in soil health and fertility while also capturing atmospheric carbon as soil organic carbon. Human activities have resulted in the degradation of one-third of the world's soils, releasing substantial amounts of carbon into the atmosphere and exacerbating climate change. Protecting soil organic matter through sustainable soil management practices is essential to sequester more carbon, maintain soil health, and enhance resilience against climate challenges. Governments must support land users in implementing these practices, presenting an opportunity to restore soil fertility, provide cleaner resources, and preserve biodiversity while helping to mitigate climate change by removing carbon from the atmosphere.

فيديو أسئلة وأجوبة

  • What is soil organic matter?

    Soil organic matter refers to the organic materials in the soil that help promote soil health, fertility, and plant growth.

  • Why is soil organic carbon important?

    Soil organic carbon plays a crucial role in capturing carbon from the atmosphere and maintaining soil fertility and health.

  • How much carbon can degraded soils release?

    Degradation of one-third of the world's soils has released up to 100 gigatons of carbon.

  • What are some ways to protect soil organic matter?

    Implementing sustainable soil management practices can protect and enhance soil organic matter.

  • How much carbon remains in the soils worldwide?

    An estimated 1,417 gigatons of carbon remain in the first meter of soil across the globe.

  • What is the impact of losing soil organic matter?

    Losing soil organic matter can increase carbon emissions and accelerate climate change.

  • What role do grasslands play in carbon storage?

    Grasslands store more than double the amount of carbon compared to all other agricultural areas.

  • Why is government support needed for land users?

    Government support is essential to help land users implement sustainable soil management practices.
