FROM THE UNDERGROUND UP: BRINGING BONE CHAR FERTILIZER TO MARKET IN ETHIOPIA
Nearly all phosphorus fertilizers are derived from mined rock phosphate. Rock phosphate is a non-renewable resource that is quickly depleting and increasingly controlled by a small number of countries. Recent price volatility on the world market and the risk of future shortfalls threaten food security for developing nations. In Ethiopia, bone char fertilizer is a promising alternative to imported phosphorus. This thesis explores the steps to bringing bone char fertilizer to the Ethiopian market. We investigate the bone residue supply chain, the impact of bone collecting on the income of collectors, and the quantities and cost of bone residues in Jimma, Ethiopia. Using experimental data, we analyze the costs and profitability of bone char production. Lastly, we explore the acceptability and willingness to pay for different formulations of granulated bone char fertilizer among Ethiopian farmers using a Vickery second-price auction format.
