Climate change has increased the frequency of extreme weather events such as heavy rainfall leading to floods in several regions. In Africa, rural communities are more vulnerable to flooding, particularly those that dwell in low altitude areas or near rivers and those regions affected by tropical storms. This study examined flood vulnerability in three rural villages in South Africa’s northern Limpopo Province and how communities are building resilience and coping with the hazard. These villages lie at the foot of the north-eastern escarpment, and are often exposed to frequent rainfall enhanced by orographic factors. Although extreme rainfall events are rare in the study area, we analyzed daily rainfall and showed how heavy rainfall of short duration can lead to flooding using case studies. Historical floods were also mapped using remote sensing via the topographical approach and two types of flooding were identified, i.e., those due to extreme rainfall and those due to poor drainage or blocked drainage channels. A field survey was also conducted using questionnaires administered to samples of affected households to identify flood vulnerability indicators and adaptation strategies. Key informant interviews were held with disaster management authorities to provide additional information on flood indicators. Subsequently, a flood vulnerability index was computed to measure the extent of flood vulnerability of the selected communities and it was found that all three villages have a ‘vulnerability to floods’ level, considered a medium level vulnerability. The study also details temporary and long-term adaptation strategies/actions employed by respondents and interventions by local authorities to mitigate the impacts of flooding. Adaptation strategies range from digging furrows to divert water and temporary relocations, to constructing a raised patio around the house. Key recommendations include the need for public awareness; implementation of a raft of improvements and a sustainable infrastructure maintenance regime; integration of modern mitigations with local indigenous knowledge; and development of programs to ensure resilience through incorporation of Integrated Development Planning.

Various strategic plans compiled by the local levels of government seek to advance the need to integrate strategic planning frameworks and improve service delivery and related content through the application of performance management tools. From the perspective of municipalities, all policies and plans at all levels of government need to be articulated with empirical based plan-level formulation and in compliance with set performance assessment criteria. Using South Africa as a case study, the methodology of the paper included a theoretical analysis of available (but applicable) performance management tools and processes. The focus and outcome were the development of a simplified performance management tool that supports elementary prioritization of projects and the setting of standards to address the growing needs, service backlogs, and informality challenges, thereby enhancing sustainable planning and development applicable to developing countries. The study findings highlight, firstly, the prevalence of persistent service delivery gaps in local government. Secondly, local government performance management and strategic plan implementation is constrained by measurement data, standards, and information gaps. Thirdly, inadequate legislative frameworks and strategic instruments applicable to local government in developing countries adds another layer of performance management gap dimensions. Fourthly, there is misalignment between policies, legislative provisions, and local needs in terms of a set of applicable measurement tools and standards relevant in a developing country. Fifthly, an oversight role gap exists in terms of clearly defining the roles and scope of responsibilities concerning performance management. These above-mentioned shortcomings read together constitute a service delivery performance management tools gap that needs to be overcome if improved service delivery is to be achieved. In view of the above-stated considerations, a simplified performance management tool to enhance service delivery in local government had to be developed. The developed simplified performance management tool assumes that the application of performance management assessment processes is to be aligned throughout all spheres of government.

Sustainability of transport infrastructure integration begins with involving an all-inclusive transportation chain instead of only focusing on one part of the journey. This is achieved by facilitating spatial integration between diverse transport modalities to allow for a multiplicity of travel opportunities. This paper unpacks the extent of the spatial integration of non-motorized transport and urban public transport infrastructure within the city of Johannesburg in South Africa. Cycling activity datasets derived from Strava Metro and the spatial data of urban public transport infrastructures were collected to demonstrate existing spatial patterns and infrastructure connectivity. Exploratory spatial data analysis and focal statistics analysis were central in the data processing. The findings reveal that cycling activities are separated from urban public transport infrastructure, and the city of Johannesburg’s transport system is characterized by spatially fragmented commuting and cycling operations, with limited to no sharing of infrastructure. Most public transport stations are not easily accessible for non-motorized transport and are characterized by inadequate cycling facilities. In conclusion, the identification of an urban public transportation catchment area becomes essential for developing cities such as Johannesburg. This can be used as tool for planning infrastructural upgrades and forecasting potential public transport ridership while also assessing the impacts of investments in transit planning. There is thus a need to integrate motorized urban public transport and cycling infrastructural developments toward promoting multi-mobility and infrastructure sharing.

Municipal infrastructure asset operations and maintenance are critical for municipalities to provide basic services to communities in South Africa. The paper discusses the performance of municipal assets using Key Informants and literature review based on three metropolitan areas in Gauteng province and four rural municipalities in Limpopo province of South Africa focusing on asset operations and maintenance. Municipal assets in South Africa are saddled with poor performance because the infrastructure is aging in a context of rapid urbanisation and population growth and this impacts on the level of service delivery to the communities. The method used to analyse and unpack the findings were obtained from the review of literature and information obtained from Key Informants. The major official documents used includes the Sector Plans, Spatial Developments Frameworks, Integrated Development Plans as well as the review of books and journals on the general performance of the metros and rural municipalities with respect to municipal asset operations and maintenance. The information obtained from the Key Informants was used to refute or confirm the notion from the literature reviewed that inadequate operations and maintenance of municipal assets contribute to under performance in the provision of basic service delivery to the communities. The study shows that insufficient funding and low revenue base of the municipalities impacts on the renewal of municipal assets and provision of basic services to the communities in both metros and rural municipalities. The study recommends appropriate systems and asset management practices that can be put in place to improve on the under-performance of operations and maintenance.

In the face of unstoppable urbanisation, disaster risks are projected to increase, mainly in unplanned areas that usually lack disaster risk reducing infrastructure. In Africa, including South Africa, limited resources and capacity hinder the provision of such infrastructure. The objective of this study was to determine options for promoting disaster risk reducing infrastructure in informal settlements in Giyani Municipality, Limpopo Province, South Africa, a disaster risk-prone area. A case study was conducted to collect primary data from purposively selected experts and the SWOT factors from the Integrated Development Plan Report of 2019/2020. A TOWS analytical hierarchical process was applied to pairwise comparisons of factors to prioritize them using eigenvalues and generate strategic options for promoting disaster risk reduction infrastructure in the informal settlements of Giyani Local Municipality. In the TOWS results, the experts suggested integrating traditional authorities into the municipal development processes, implementing an environmental framework that includes disaster management policies and an integrated waste management plan, and developing innovative technological projects that provide up-to-date spatial planning data to provide disaster risk reducing infrastructure in informal areas. This study concludes that the provision of affordable housing, clean regular piped water, storm and sewer drainage systems, street lighting, accessible routes, solid waste collection, electricity, and healthcare services would reduce a range of disaster risks.
