World Soil Day, held every year on 5 December under the leadership of the Food and Agriculture Organization of the United Nations (FAO), aims to raise awareness of the essential role soils play in sustaining ecosystems, supporting climate action, enabling food production and underpinning the sustainable use of natural resources. Although soils are rarely discussed in everyday conversation, they form one of the fundamental pillars of life on Earth and are among humanity’s most vital natural resources. This year, the focus is placed specifically on soils in urban environments.
