The objective of this book is to better understand the nature of urban governance regarding the provision of basic urban services in rapidly growing mid-sized towns and cities in developing countries. Set within the context of understanding urban planning and management within the wider city setting, the study focuses on the provision of the basic urban services of housing, water and sanitation especially within informal settlements. Using the case study of the mid-sized city of Jayapura, Papua, Indonesia, the publication explores: (i) the types, processes, and stakeholders that constitute formal urban governance in the provision of basic urban services; (ii) understanding how stakeholders gain and benefit from on the ground formal service arrangements, and why; and (iii) for those who do not directly benefit from the formal arrangements, how individuals, groups and communities organize and access governance to meet their basic urban needs. The methods employed to better understand the nature of urban governance and its relationship to the provision of basic urban services comprised primary (face-to-face household surveys interviewing 448 respondents, ground mapping at a plot size level in four informal settlements, and semi-structured interviews with 12 stakeholders) and secondary data regarding urban governance, planning and management. The study reveals that urban governance arrangements in fast growing mid-sized cities have emerged both formally and informally to cope with basic urban service needs across a range of settlement types and socio-cultural groups. The major modes of governance arrangements in the informal settlements consist of traditional, formal and informal, and hybrid governance which co-evolve as their boundaries overlap and intersect through time at varying levels of equilibrium. The governance equilibrium represents a balance at a specific point and place in time in how stakeholders utilize and share resources,and access various contributions.
