Abstract for: Model-Based Strategy Design for Biowaste Recovery in Addis Ababa, Ethiopia
In order to improve the performance over time of waste management in cities in low and middle-income countries new strategies need to be developed, tested, and implemented. Biodegradable waste (biowaste) should be the primary focus of any strategic design effort, as it corresponds to the largest fraction of household waste in urban centers, which still remains to a large extent unrecovered. Therefore, applying the Strategy Dynamics framework developed by Warren (2008), which uses System Dynamics to develop resource-based strategies, a strategic architecture has been designed for the case study of biowaste management in Addis Ababa, Ethiopia. The strategic architecture consists of all the necessary strategic resources needed achieve the desired performance over time, the flows that cause the resources to grow and be depleted, and the factors that control these flows. For this case study, the strategic architecture includes the administrative units involved in implementation, households separating biowaste, the biowaste collection capacity, the compost production capacity, and the market for compost. Based on the analysis of the performance of the proposed strategy recommendations for the city of Addis Ababa are made.
