A day to pause and come down to earth, Pg8

Key Highlights:

• World Soil Day is observed annually on December 5, established by the Food and Agriculture Organization (FAO).
• The theme for 2025 is "Healthy Soils for Healthy Cities," focusing on the importance of urban soils.
• Over 56% of the global population lives in cities, facing challenges like food insecurity, pollution, flooding, and extreme heat.
• Urban soils act as living filters, natural sponges, and carbon sinks, contributing to urban resilience.

Detailed Insights:

• Urban soils help combat climate change and extreme heat by absorbing heat and sequestering atmospheric carbon.
• Healthy soils prevent floods by absorbing rainfall, filtering it, and replenishing groundwater.
• Urban agriculture, including rooftop farms and backyard plots, relies on fertile soil, shortening food chains and enhancing local resilience.
• Contact with nature in urban green spaces reduces stress, anxiety, and depression, promoting physical activity and improving mental health.
• Urban soils are often degraded due to contamination, compaction, loss of organic matter, and sealing by concrete and asphalt.
• The "Healthy Soils for Healthy Cities" campaign promotes urban soil restoration, green infrastructure, urban agriculture, responsible soil management, and soil literacy.
• Actions include rehabilitating degraded land, limiting soil sealing, replacing concrete with soil-based solutions, and promoting community gardens.
• Responsible soil management involves reducing chemical fertilizers and pesticide use, planting native species, and protecting topsoil with mulching.

Key Concepts Involved:

• Urban Soil: Soil found in urban environments, crucial for ecological balance and human well-being.
• Green Infrastructure: Strategically planned networks of natural and semi-natural areas designed to deliver a wide range of ecosystem services.
• Soil Degradation: The decline in soil quality caused by improper use, usually for agricultural, industrial, or urban purposes.
