Focus: UN days, SDGs, climate resilience, sustainable land & water management
World Soil Day 2025 is observed on 5 December with the global theme “Healthy Soils for Healthy Cities”, highlighting the vital role of urban soils in food security, climate resilience, and sustainable development, and calling for sustainable soil management from farms to fast‑growing cities[web:139][web:141][web:144][web:146].
World Soil Day (WSD) is an official UN observance held every year on 5 December to raise global awareness about the importance of healthy soil and to advocate for sustainable soil management. The 2025 celebrations focus on the theme “Healthy Soils for Healthy Cities”, drawing attention to how urban soils—often hidden under asphalt and concrete—regulate temperature, store water, filter pollutants, and support food production and biodiversity in city landscapes[web:139][web:141][web:146].
The Food and Agriculture Organization (FAO) of the United Nations warns that over 95% of global food production depends on soils, and more than 3.2 billion people are directly affected by land and soil degradation worldwide[web:138][web:145][web:146]. Soil degradation through erosion, sealing, contamination, salinisation, and loss of organic matter threatens food security, climate stability, and urban liveability. World Soil Day 2025 is therefore framed as a call to action for governments, city planners, farmers, and citizens to “build healthy cities from the ground up” through better soil protection, monitoring, and management[web:139][web:141][web:147].

World Soil Day 2025 Theme: “Healthy Soils for Healthy Cities”
🌆 Why Focus on Cities?
- Urbanisation Surge: By 2050, an additional 2.5 billion people are expected to live in cities, placing immense pressure on urban land and soil resources[web:138][web:139][web:141].
- Soil Sealing: Roads, buildings, parking lots, and pavements seal the soil, blocking its ability to absorb water, store carbon, host biodiversity, and regulate temperature[web:139][web:147].
- Urban Heat Islands: Healthy, vegetated soils help cool city microclimates, while sealed surfaces intensify heat waves and energy demand[web:139][web:146].
- Flood Risk: Unsealed soils act like natural sponges; sealing accelerates runoff, causing urban flooding and waterlogging[web:139][web:147].
- Urban Food & Gardens: Properly managed city soils support urban farming and community gardens, which can provide up to 10% of vegetables, legumes, and tubers globally[web:147].
🏙️ Functions of Urban Soils (Key for Exams)
- 🌡️ Temperature Regulation: Cool the air, reduce heat‑island effect in cities[web:139][web:147].
- 💧 Water Storage & Filtration: Absorb rainfall, recharge groundwater, and filter pollutants, reducing flood risk[web:138][web:139].
- 🌱 Biodiversity Support: Host microorganisms, invertebrates, plant roots—up to 59% of Earth’s species depend on soil ecosystems[web:138].
- 🌾 Food Production: Support peri‑urban and urban agriculture, enhancing local food security[web:138][web:147].
- 🌍 Carbon Storage: Act as major carbon sinks, helping mitigate climate change through CO₂ sequestration[web:138][web:146][web:147].
⚠️ Main Threats to Urban & Rural Soils
- Soil Sealing & Urban Sprawl – concrete, asphalt, infrastructure covering fertile land[web:139][web:147].
- Soil Erosion – wind & water erosion removing fertile topsoil, reducing yields[web:138][web:146].
- Industrial & Chemical Pollution – heavy metals, pesticides, industrial waste contaminating soils[web:138][web:144].
- Unsustainable Agriculture – monocropping, excessive fertilisers, and deep tillage degrading soil structure & biodiversity[web:138].
- Climate Change – extreme droughts, floods, and heat stress further damage soil systems[web:138][web:146][web:147].
History & Significance of World Soil Day
How World Soil Day Started
- 2002: Concept proposed by the International Union of Soil Sciences (IUSS) to create a dedicated global soil day[web:141][web:144].
- 2013: FAO Conference endorses World Soil Day; later that year, the UN General Assembly formally recognizes 5 December as World Soil Day[web:141][web:144][web:145].
- Date Significance: 5 December chosen in honour of King Bhumibol Adulyadej of Thailand, a strong advocate of sustainable soil management[web:144].
- 2014: First official UN‑recognized World Soil Day celebrated globally[web:144][web:145].
Why World Soil Day Matters (Exam-Ready Points)
- More than 95% of the world’s food depends on soil health[web:138][web:144].
- Soils provide 15 of 18 essential plant nutrients, essential for crop quality & human nutrition[web:144][web:146].
- Land degradation directly threatens the well‑being of at least 3.2 billion people globally[web:138][web:141][web:147].
- Soils serve as a major carbon sink, critical for meeting Paris climate targets and SDGs[web:138][web:146][web:147].
- Degraded soils contribute to “hidden hunger”—micronutrient deficiency affecting ~2 billion people worldwide[web:138].
