“…It is, therefore, estimated that between 2010 and 2030, a period of 20 years, the government will be able to increase the urban share of the population from 52% to 65% [66], which evidence is shown in Table 4. The built-up area of the municipality increased by 8.37 km 2 between 1984 and 1986 which compares to 6.14 km 2 in 1986 obtained by [67]. The same author obtained 20.12 km 2 increase in 2001 compared to our results of 35.09 km 2 by 2000.…”

Decentralization problems in Africa have caused some infrastructure disparity between country capitals and distant districts. In Ghana, less public investment has created a gap between implementation results and theoretical benefits. Spectral indices are a good approach to extracting impervious surfaces, which is a good method of measuring urbanization. These are restricted by complexity, sensor limitation, threshold values, and high computational time. In this study, we measure the urbanization dynamics of Wa District in Ghana by applying a proposed method of impervious surface extraction index (ISEI), to evaluate the decentralization policy using Landsat images from 1984–2018 and a single S2A data. Comparing our proposed method with five other existing indexes, ISEI provided good discriminated results between target feature and background, with pixel values ranging between 0 and +1. Other indexes produced negative values. ISEI accuracy varied from 84.62–94.00% while existing indexes varied from 73.85–90.00%. Our results also showed increased impervious surface areas of 83.26 km2, which is about 7.72% of total area while the average annual urban growth was recorded as 4.42%. These figures proved that the quantification of decentralization is very positive. The study provides a foundation for urban environment research in the context of decentralization policy.

“…Clearly, land is of critical essence to the teeming populace whose livelihood depends on agriculture. However, a major threat to urban agriculture is the rapid transformation of large tracks of arable agricultural land to urban land use and its corresponding changes to livelihoods Osumanu et al 2019). In an agrarian economy, agriculture is crucial and is the main source of livelihood for a significant proportion of the population: landlessness could be the greatest of deprivation and livelihood risks (Yeboah 2014).…”

“…The urbanization process in Wa has been quite rapid, though expected in the far future. Unlike other cities in Ghana including Tamale, Kumasi, Sekondi-Takoradi, Accra and Tema with features associated with urbanization, the Wa Municipality was patches of villages some two decades or more ago (Osumanu et al 2019). From patches of villages to a municipality, the demand for land for urban activities which were initially used for agricultural production has increased geometrically.…”

“…Kuusaana and Eledi (2015), using customary land allocation and its implication on food systems in the Wa Municipality, provide some evidence but quite narrow in scope. Other studies concentrated on the development trajectory of Wa into municipality and increasing population while some also focused on compliance with land use regulations as a result of urban sprawl (Ahmed et al 2020;Korah et al 2018;Osumanu et al 2019). While all these studies are relevant in providing scientific evidence on the development of Wa as a Municipality, they overlooked the livelihood adaptation strategies of indigenous farmers whose agricultural lands have been taken over by urban development.…”

“…Just like other urban areas in Ghana and Africa, the increasing population of Wa is of major concern to town planners and researchers. The conversion of agricultural land for activities of urbanization to include residential commercial and industrial purposes has taken a toll in recent years (Osumanu et al 2019; Kusaana and Eledi 2015). The continuous need for urban development and the subsequent change in land use due to urbanization is diminishing the size of land needed for agricultural purposes.…”

Translating Globalised Ideals into Local Settings: The Actors and Complexities of Post-settlement Water Infrastructure Planning in Urban Ghana

Following the principles of the networked city and urban planning, pro-active planning of water infrastructure is pertinent for attaining universal water access. Ironically, in cities of the Global South, water infrastructure provision takes the form of post-settlement networks—where human settlements evolve to steer the provision of the large-scale water network. However, little is known about the complexities, the processes and motives, the actors involved and how they navigate towards universalising water access. I investigate this kind of infrastructure planning ideal, drawing inspiration from technological translations from the Global North to the Global South, using the case of Wa, a secondary city of Ghana. The study revealed that off-grid water systems initially served water in secondary cities. The large-scale water network later evolved as a “reactive measure” driven by the rise in population, and the failure of the off-grid water infrastructure to attain universal water access. Despite that, resistance from residents, spatial disorder and sprawling growth, utility policies and in capabilities challenged the efforts of the state utility towards attaining a universal water supply. Through creativity, the utility providers negotiated and invented multiple models of water supply contradictory to the “mono-modal” principles of the networked city. This produced and segregated water access across the urban zones of the city. The findings suggest that though the post-settlement water network provision represents an attempted translation of the networked city ideal, in practice, it does not conform with the hegemonic premise of a networked city to foster universal water supply in the cities of the Global South.
