Soil degradation and low fertility have hindered agricultural productivity in Ethiopia, threatening food security. The ETH-Soil project, launched in 2021 by the Deutsches Biomasseforschungszentrum (DBFZ) and funded by Germany’s Federal Ministry for Economic Cooperation and Development, is addressing these challenges with innovative biochar-based solutions.

BiocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More, derived from agricultural residues through pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More, is combined with compost or biogas digestates to create nutrient-rich fertilizers. When applied to degraded soils, this mixture enhances water retention, reduces nutrient loss, and promotes microbial activity, resulting in improved soil fertility and crop yields. Additionally, the biochar sequesters carbon, contributing to climate change mitigation.

To date, the project has trained 244 smallholder households in Ethiopia’s Oromia region to use these fertilizers, improving yields on 16.6 hectares of farmland. Quality-assured biochar has been distributed in pilot districts, with some farmers producing their own biochar blends. Encouraged by success, neighboring communities are adopting the technology, with plans for widespread local production starting in 2025.

Looking ahead, ETH-Soil aims to certify and commercialize carbon sink credits to incentivize adoption. The project also integrates sustainable cooking technologies for biochar production and incorporates findings into agricultural education at Ethiopia’s University of Jimma.

Through collaboration with research, education, and local institutions, ETH-Soil aligns with the 2030 Agenda for Sustainable Development, fostering long-term resilience for Ethiopia’s rural farming communities.
