Farmer-Managed Natural Regeneration: A Simple Solution Transforming Niger
In the 1980s, Australian agronomist Tony Rinaudo made a groundbreaking discovery in Niger that would revolutionize land restoration in arid regions. Confronted by widespread deforestation and soil degradation, he noticed small shoots sprouting from tree stumps in the barren landscape. These dormant “underground forests,” consisting of tree roots and seeds, held the key to regenerating ecosystems. His method, Farmer-Managed Natural Regeneration (FMNR), has since transformed millions of hectares of degraded land in Niger and beyond.
The Challenge: Degraded Lands and Vulnerable Communities
Niger, a Sahelian country bordering the Sahara, has long battled desertification and the consequences of deforestation. Drought, soil erosion, and barren farmlands left farmers struggling with poor crop yields and food insecurity. Traditional reforestation efforts—such as planting new tree seedlings—often failed due to high costs, poor survival rates in extreme conditions, and insufficient water resources.
The Solution: Reviving Nature’s Hidden Potential
FMNR is a low-cost, scalable method that leverages existing natural resources. Rather than planting new trees, farmers protect and nurture regrowth from tree stumps, roots, and seeds already present in the soil. By selectively pruning weaker shoots and safeguarding young trees from grazing and fires, FMNR enables rapid regrowth of trees with established root systems. This process produces stronger, more resilient trees that restore soil fertility, provide shade, and enhance biodiversity.
Farmer-Managed Natural Regeneration (FMNR) is a low-cost, sustainable land restoration technique that uses the natural regrowth of trees and shrubs from stumps, roots, and seeds already present in the soil. It is based on three key principles:
1. Using Existing Resources
FMNR focuses on the “underground forest”—the tree stumps, roots, and dormant seeds that remain even in degraded landscapes. These resources are already adapted to local conditions and can regrow rapidly if managed properly. Unlike traditional reforestation, FMNR does not rely on external inputs such as nursery-raised seedlings, making it an accessible solution for resource-limited farmers
2. Selective Pruning and Thinning
Farmers identify and manage the most promising shoots emerging from stumps or roots. They selectively prune weaker growth, leaving 3-5 stems per tree to ensure the remaining shoots receive sufficient nutrients and sunlight. This stimulates faster and healthier growth, leading to taller and straighter trees. These trees are less likely to compete with crops for resources, balancing agriculture and regeneration
3. Community Engagement and Governance
The success of FMNR depends on community participation and shared ownership. Farmers collectively agree on rules for protecting regenerating trees from threats such as grazing, burning, and unauthorized cutting. Supportive policies, such as legal frameworks allowing farmers to benefit from tree products, further incentivize long-term commitment. This collaborative approach ensures sustainable management of the restored landscape
A Global Model for Regeneration
The impact of Farmer-Managed Natural Regeneration (FMNR) in Niger has been transformative. Over 7 million hectares of previously degraded land have been restored, with an estimated 200 million new trees now thriving. These regenerated trees have improved soil fertility, reduced erosion, and created microclimates that support biodiversity. For farmers, this environmental revival has translated into tangible benefits. Crop yields have increased by about 50%, providing more food for families and reducing hunger. Additionally, incomes have doubled as farmers sell sustainably harvested timber, firewood, and other tree products
The environmental changes have also boosted climate resilience. Trees from FMNR help retain soil moisture, provide shade for crops, and protect the land from extreme temperatures, making it more drought-resistant. Beyond environmental and economic gains, FMNR has empowered communities by providing knowledge and skills to sustain the initiative, ensuring that the benefits of regeneration endure for generations.
