• 🌱 Soil health is sensitive to changes in runoff, acidity (pH), and chemical amendments stemming from mine discharge
• 🌾 Farming communities face potential loss of land and uncertainty around future productivity

• 🌍 Biodiversity and ecosystem services need proactive planning to coexist with mining
• 🔄 Adaptive management frameworks help track and respond to emerging challenges in land use
• 🔒 Containment plans are crucial to protect downstream lands
• 📈 Strategic land repurposing (rehabilitation) should follow mine closure

Potential Changes to Land Use

1. Direct conversion of forest or agricultural lands to mine infrastructure, transport corridors, and waste storage
2. Altered hydrological regimes affecting adjacent crops, grazing lands, and forests
3. Decreased soil productivity and increased erosion or contamination risks
4. Changes in access to traditional hunting, fishing, and gathering spaces for indigenous communities

Environmental Stewardship & Management Strategies

Central to the pebble mine status debate is the role of rigorous environmental stewardship, management frameworks, and sustainable land-use plans. Responsible mining demands a blend of:

• 📊 Assessment frameworks covering catchment-scale impacts to soil and water
