Case Study: Humbo, Ethiopia

The Humbo project in Ethiopia restored 2,700 hectares of land from 2006 onwards using Farmer-managed natural regeneration (FMNR), a low-cost method where farmers prune native tree stumps and root systems. Supported by World Vision and the World Bank's BioCarbon Fund, the project integrated carbon sequestration payments with community-led land management. Key success factors included secure land rights, the use of endemic species, and the creation of community cooperatives. While the project improved soil health, reduced erosion, and increased firewood availability, it faced challenges regarding the high transaction costs of Clean Development Mechanism (CDM) compliance and delays in carbon payments.

• The restoration project covered 2,700 hectares in the Humbo region, utilizing Farmer-managed natural regeneration (FMNR) where farmers allow native trees and shrubs to regrow from existing live stumps, root systems, and seedbanks.
• The project's technical design relied heavily on existing ecological conditions, with over 90 percent of the area requiring no replanting from nurseries because regeneration was achieved through selecting and pruning existing stumps.
• Financial incentives were provided through the World Bank's BioCarbon Fund, which pledged to purchase 165,000 tons of Carbon Emission Reduction credits, expected to generate over US$700,000 for local communities over ten years.
• A critical enabling factor for the project was the shift in land ownership from the state to local people, facilitated by the Federal Rural Land Administration and Land Use Proclamation No. 456/2005 and Rural Land Administration and Utilization Proclamation No. 53/2003.
• The project resulted in several observed environmental and social benefits, including reduced flooding, erosion, and siltation, as well as increased availability of domestic firewood and the return of wildlife.
• Compliance with the Clean Development Mechanism (CDM) standards introduced significant complexity and high transaction costs, requiring extensive work to demonstrate additionality and quantify leakage.
• Economic motivation was hindered by a nearly four-year delay before farmers received carbon payments and subsequent low prices per ton of carbon, which reduced interest in further participation.
