“…As a consequence, there are instances where floodwaters inundate a section of the road for extended periods, and in extreme cases, the road is completely cut off due to erosion and washed-away bridges [32]. The impact of such flooding on the transport system, particularly the road network, is not uniform across all cities [36,37]. Some sections of the road network may be more affected than others due to their differential exposures to flooding.…”

Climate change seriously threatens human systems, properties and livelihoods. Global projections suggest a continuous increase in the frequency and severity of weather events, with severe outcomes. Although the trends and impacts are highly variable depending on location, most studies tend to concentrate on either the urban or rural areas, with little focus on peri-urban areas. Yet, in Sub-Saharan Africa, peri-urban areas display unique characteristics: inadequate infrastructure, unplanned development, weak governance, and environmental degradation, all of which exacerbate flood impact and thus need academic attention. This study contributes to filling this gap by assessing the flood vulnerability of roads in peri-urban Accra and its implications for mobility. Based on the fieldwork, the study delineated and analysed potential zones within the research locations. The researchers calculated roads’ absolute and relative lengths, using a spatial overlay (intersection) of potentially flooded roads with the total road network within the grid cells of 500 m by 500 m. These measures were adopted and used as exposure measures. The findings revealed that over 80% of roads with lengths between 100 m and 500 m were exposed to floods. Some areas had higher exposure indices, with absolute road lengths ranging from 1.5 km to 3.2 km and relative road lengths between 0.8 and 1.0. There were significant variations in road exposure between and within neighbourhoods. Depending on the depth and duration of the floodwater, residents may be unable to access their homes or carry out their daily activities. In conclusion, this study highlights the differential vulnerability of peri-urban areas to road flooding and recommends targeted provision of flood-resilient infrastructure to promote sustainable development.

This review examines current knowledge in the literature on informal settlements, specifically those contributions that include emphases on governance and the role of public administration. Given that informal settlements task the public sector with specific challenges that test the limits of infrastructure, while also presenting considerable human demands, there is a need to better understand how informal settlements and governments’ capacities to respond to such phenomena potentially deepen concerns with already vulnerable populations. After an introduction to the concept of informal settlements, the paper considers the approach to the literature review, which included an initial group of 272 papers from peer-reviewed, English-language journals, from the period 2019 to June 2024. Major themes are discussed, with opportunities for future research identified. Informal settlements are still an emerging topic within the larger land use and urban planning literature, but the significance of this research extends beyond the immediate areas of the settlements themselves to critical areas of governance and vulnerability study.
