Case Study: Humbo, Ethiopia

This case study examines a forest landscape restoration project in the Humbo District of Ethiopia, implemented from 2006 to the present. Led by World Vision with support from the World Bank's BioCarbon Fund, the project utilized Farmer-managed natural regeneration (FMNR) to restore 2,700 hectares of land, leveraging carbon sequestration payments and community-led management to combat severe deforestation and soil degradation.

• The Humbo restoration project focused on restoring approximately 2,700 hectares of land using Farmer-managed natural regeneration (FMNR), a process where farmers allow native trees and shrubs to regrow from existing root systems, stumps, and seedbanks, selectively pruning them to maintain density.
• The project was designed to provide both environmental and economic benefits. Environmental gains include reduced flooding, erosion, and siltation, as well as increased wildlife presence. Economic benefits include a new revenue stream from carbon sequestration payments and the production of firewood, berries, fruits, and nuts from indigenous species.
• Financial incentives were provided through the World Bank’s BioCarbon Fund, which pledged to purchase 165,000 tons of Carbon Emission Reduction credits, projected to generate over US$700,000 for local communities over ten years.
• The project's success was enabled by specific ecological and policy conditions. Ecologically, over 90 percent of the area did not require costly replanting because native source populations were already present as stumps and root systems. Legally, the transition of land ownership from the state to local people via federal proclamations in 2003 and 2005 provided necessary security of land rights.
• To ensure the success of restoration, the project addressed competing land uses by providing alternative livelihoods for those who relied on the areas being fenced off. These alternatives included honey-bee hives, poultry, fruit trees, medicinal plants, spices, and employing charcoal makers as guards of communal lands.
• The project faced challenges regarding the timing and value of economic rewards. Farmers waited nearly four years for carbon payments to begin, and subsequent low prices per ton of carbon reduced interest in further participation among some farmers.
• The requirement to meet Clean Development Mechanism standards for carbon credits introduced significant complexity and transaction costs. This included the need to demonstrate additionality, account for leakage, and produce a 100-page project design, making the project reliant on external finance and capacity.
