Ayele, Megento and Yeshitela make green-space durability a governance problem. Focusing on urban parks and community green spaces in Addis Ababa, the study combines qualitative and quantitative methods to examine management models, governance principles and institutional barriers. It identifies weak park governance, land conversion, limited inter-sectoral cooperation and deficiencies in integrated management, while also detecting a movement toward user-centred community governance. The key conceptual operation is to separate the existence of a green-space designation from the institutional arrangements capable of sustaining that designation over time. Governance appears across strategic, tactical and operational levels and through both formal and informal actor networks. The theoretical contribution is therefore processual: green space is continuously reproduced through authority, maintenance, participation and management rather than secured once by a master plan. The paper bridges urban ecology and institutional analysis by showing that environmental performance depends on who decides, who maintains, who participates and how responsibilities are distributed.
