Soil Degradation: Foundations at Risk

Soil degradation is at the very heart of the top environmental issues Philippines faces. It jeopardizes food production, reduces yields, and undermines the sustainability of rural agricultural systems. The Philippines’ unique geology and climate, coupled with continuous cropping, deforestation, and poor management practices, mean that over 50% of arable land exhibits some degree of degradation.

How Soil Degradation Happens

• • Soil erosion – heavy rains and unsustainable land clearing wash away topsoil in upland and hilly areas.
• • Loss of organic matter and nutrients – intensive cropping without replenishment depletes soils.
• • Soil salinization – especially in coastal areas, driven by seawater intrusion and poor irrigation methods.
• • Compaction and crusting – heavy machinery, overgrazing, and lack of soil cover.

Impacts of Soil Degradation

1. Reduced soil fertility and nutrient depletion
2. Lower crop yields and food insecurity
3. Increased vulnerability to droughts and erratic rainfall
4. Heightened sediment load in waterways and reservoirs, clogging irrigation systems
5. Greater risks of landslides and disasters in hilly and upland regions

Best Practices for Soil Conservation & Restoration
