National biomass profile: monitoring the biomass potentials in Ethiopia

The German-Ethiopian cooperation project ETH-Soil (2021 - 2026), funded by the German Federal Ministry for Economic Cooperation and Development (BMZ), aims to improve soil fertility and food security in the Oromia region through the use of biofertilisers derived from the products of pyrolysis and biogas plants. Through eleven work packages, the project will address challenges such as combating hunger (SDG 2), supporting sustainable natural resource management (SDG 12), and reducing land degradation (SDG 15), but will also focus on technology and knowledge transfer to ensure long-term implementation success.

The quantification of national biogenic resources provides a first important overview of the biomass potentials for energy and material use, e.g. production of organic fertilisers, in the context of a circular economy. Therefore, as part of the ETH-Soil project, we are conducting assessment of biomass potentials using an automated workflow in R. This involves identifying relevant data and querying international databases to compile key biomass information from various sources in a structured manner.More specifically, we identify the most relevant crops and agricultural residues and animal excreta along with mapping production patterns. As a result of this compilation and data review, the resulting National Biomass Profile will not only contain the status quo of biomass potentials, but also time series that will allow analyses of interannual production stabilities. It will furthermore enable project participants and local stakeholders to follow the development of the compiled key figures through automatic data updates. Thereby, in the context of the ETH-Soil project, it will serve as a decision support tool in e.g. the identification of suitable sites for pyrolysis and biogas plants.

With this contribution we describe the chosen approach and present our results exemplarily for Ethiopia.
