Independent erosion and conservation-planning study · Anambra State
Anambra Soil-Erosion Prioritization
Where should Anambra investigate soil-erosion control first? Explore mapped planning areas grouped into three relative priorities with conservation scenarios and local-government comparisons.
Project objective
Direct early erosion-control investigations toward places needing attention.
Soil erosion removes productive material from landscapes and can carry sediment toward drainage networks. I integrated terrain, land-cover, rainfall, soils and drainage-related evidence to screen Anambra for places where conservation planning or field investigation may be useful. The resulting priority zones are planning units, not verified erosion damage, guaranteed soil-loss reduction or construction-ready designs.

My contribution
Connecting erosion conditions and sediment pathways to planning.
I built a repeatable GIS workflow from environmental input quality checks through modelled erosion and drainage evidence, zone screening, conservation scenarios and public cartography.
Model potential soil loss
Applied an erosion-screening framework to compare conditions affecting soil detachment rather than measuring actual sediment exported by streams.
Examine drainage connectivity
Considered how terrain and pathways might influence movement toward drainage networks.
Identify planning zones
Established 441 mapped zones in three relative priority groups, preserving their scientific classifications.
Summarize local needs
Linked zones to local-government summaries while documenting assignment confidence and boundary limitations.
Explain conservation scenarios
Presented illustrative management scenarios without calling modelled reductions guaranteed field results.
Spatial workflow
From erosion-related conditions to planning zones.
- 01Prepare
Align and quality-check environmental datasets and analytical grid.
- 02Estimate
Examine modelled soil-loss patterns and drainage-related context.
- 03Prioritize
Group candidate areas into three relative screening tiers.
- 04Compare
Summarize planning zones and a relative modelled delivery index by local government.
- 05Publish
Present clear interactive maps, professional cartography and the limits of the screening.
Outputs and value
A screening tool for informed conservation planning.
The results provide locations where erosion-management investigations may be directed first. Local consultation, site visits and engineering verification remain essential before choosing or building an intervention.
