MISE À ÉCHELLE DU REVERDISSEMENT: SIX ÉTAPES VERS LE SUCCÈS

The document argues that regreening, primarily through Farmer-Managed Natural Regeneration (FMNR), is a cost-effective solution for restoring degraded landscapes in Africa's arid zones. It details a six-step strategy for scaling these efforts: identifying existing successes, building a community of champions, resolving policy and legal barriers, implementing communication strategies, developing agroforestry value chains, and filling knowledge gaps through research. The report highlights significant achievements in Niger, where 5 million hectares have been regreened, and emphasizes the multiple economic, environmental, and social benefits of integrating trees into agricultural systems.

• Farmer-Managed Natural Regeneration (FMNR) is identified as a simple, low-cost, and highly effective method for increasing tree density in fields by protecting and managing the natural regrowth of trees and shrubs from existing root systems or seeds in the soil.
• In Niger, farmers have successfully regreened 5 million hectares since 1985, representing nearly 50% of the country's total cultivated area.
• Regreening provides diverse benefits, including improved soil fertility through organic matter and nitrogen fixation (e.g., Faidherbia albida), increased food security, provision of fuelwood and fodder, and carbon sequestration to mitigate climate change.
• The report proposes a six-step pragmatic approach to scale up regreening: 1) Identify and analyze existing successes; 2) Form a community of champions; 3) Resolve policy and legal issues; 4) Implement a communication strategy; 5) Develop agroforestry value chains; and 6) Develop research activities.
• Policy and legal barriers, particularly regarding tree ownership and land tenure, often hinder the scaling of regreening; farmers are more likely to invest when they have clear, legally confirmed rights to use and benefit from the trees on their land.
• Regreening is significantly more cost-effective than conventional tree planting; in the Maradi and Zinder regions of Niger, external investment costs were estimated at less than 20 USD per hectare, compared to traditional projects that can cost 1,000 USD or more per hectare.
• The use of mass media, such as rural radio and documentaries, is critical for changing behaviors and reaching millions of smallholders to catalyze the adoption of regreening practices.
• Regreening helps farmers adapt to climate change by reducing wind speeds and lowering soil surface temperatures, which protects crops from extreme heat and erosion.
