Invasive mesquite in South Africa reveals systemic land degradation patterns and collaborative restoration potential

The spread of mesquite in South Africa echoes historical patterns of land degradation following colonial land use changes, including deforestation and unsustainable agriculture. Similar ecological shifts occurred in the American Southwest and Australia, where invasive species were introduced for economic purposes but later became ecological liabilities.
The mesquite invasion in South Africa is not an isolated ecological problem but a symptom of deeper systemic land degradation rooted in colonial land use and climate stressors.
By integrating Indigenous knowledge, scientific research, and community-led restoration, it is possible to develop adaptive land management strategies that address both ecological and socio-economic challenges. Historical parallels in the American Southwest and Australia suggest that long-term success depends on systemic reforms that recognize the agency of local communities and the complexity of ecological systems. Cross-cultural insights from the Sahel and East Africa further demonstrate that invasive species can be managed through holistic, culturally grounded approaches that prioritize sustainability over eradication.
