Mining-Induced Environmental Degradation Assessment
Active and abandoned mining footprints, vegetation change, erosion and altered drainage assessed across Jos South and Barkin Ladi to support remediation planning.
Project objective
Make the spatial footprint of mining degradation visible and measurable.
The assessment examined mining-related disturbance across Jos South and Barkin Ladi, combining remote sensing, existing datasets and field observations to identify degraded surfaces, vegetation impacts, erosion, mine ponds and drainage alteration.

My contribution
Mapping degradation patterns for remediation decisions.
I translated satellite and field evidence into an integrated spatial account of mining disturbance and environmental risk.
Land-cover change
Quantified land degradation and vegetation loss using LULC classification and change analysis.
Vegetation impact
Applied NDVI to assess mining-related changes in vegetation health and ecosystem condition.
Erosion and drainage
Identified erosion-prone surfaces and altered drainage patterns linked to mining.
Spatial validation
Integrated field observations and secondary evidence to check mapped impacts.
Remediation outputs
Produced thematic maps supporting impact reporting and remediation planning.
Spatial workflow
From disturbance detection to remediation evidence.
- 01Inventory
