Urban green spaces are useful natural assets that support the development of cities in diverse ways. However, statistics show that these spaces are under severe threat with the situation in Africa been critical. This study sought to assess the governance of urban green spaces and develop sustainable strategies to address problems affecting the development of urban green spaces in the context of Africa. The case study design was used and Kumasi Metropolis (Ghana) was selected as the study area. Different qualitative research techniques were employed whilst representatives of green spaces organisations and the local people constituted the study population. The study revealed that there is poor state of urban green spaces in Kumasi with factors such as urbanisation, poor enforcement of development controls, conflicting land ownership rights on green spaces, and lack of priority to green spaces being among the major causes for that. This problem was further exacerbated by complexity in the governance of green spaces, poor regulation of power among stakeholders, lack of community participation, and lack of consensus in decisions on green spaces. Sustainable strategies recommended to address the situation include controlling encroachment of green spaces, prioritising green spaces and building stronger collaborative governance for green spaces
