Restoring Mine-Degraded Land

Summary

Mining can leave land stripped of vegetation, with damaged soils and disrupted water flows. This applied field research examined ecosystem restoration and land rehabilitation in mining-degraded areas of Filabusi, exploring approaches to restore environmental services and the landscape's ability to function.

Context

Filabusi is a mining area where extraction has left parts of the landscape degraded. Degraded mine land often loses the vegetation, soil structure and water regulation that surrounding communities and ecosystems depend on.

The problem

Rehabilitation after mining is frequently incomplete or absent. Without restoration, degraded sites continue to erode, can affect water quality and remain unproductive for communities nearby.

The question we asked

What approaches can restore environmental services and landscape function on land degraded by mining?

Approach

The work involved field research in mining-degraded areas, assessing site conditions and exploring restoration and rehabilitation approaches suited to the local landscape, with attention to how environmental services such as vegetation cover, soil stability and water regulation could be recovered.

What changed

The research built an evidence base on ecosystem restoration and land rehabilitation in mining-degraded areas, and explored practical approaches to restoring environmental services and landscape functionality.

Limitations

We publish what this case cannot yet show, so others can build on it accurately.

Field research identifies promising approaches; their long-term effectiveness requires monitoring over many years.
Restoration outcomes depend on site-specific conditions and may not transfer directly to other mining areas.
Rehabilitation also depends on regulation, enforcement and the commitment of mining operators.

What we learnt

Restoration must be planned around the specific damage at each site.
Recovering environmental services, not just planting vegetation, is the real measure of success.

Why it matters beyond this case

As demand for minerals grows, so does the area of land affected by mining. The case connects ecosystem restoration with environmental governance, and with the responsibility to leave landscapes able to support people after extraction ends.

Questions for further research

Which restoration approaches recover soil and water function fastest on mine-degraded land?

How can rehabilitation obligations be made more effective in small-scale and artisanal mining areas?
