- Description: The Constitution of the Republic of South Africa mandates municipalities to provide sustainable services to communities, particularly those responsible for water and sanitation. Despite this obligation, many communities in the Oliver Reginald Tambo District Municipality (ORTDM) face prolonged water interruptions due to challenges with infrastructure. This study has assessed the ORTDM’s efforts to integrate sustainability principles into its water supply distribution systems development programmes. Essentially, it aimed to evaluate whether and how ORTDM integrates social, environmental, economic, engineering, and project management sustainability principles into its developmental initiatives. Grounded in the backdrop of global sustainable development imperatives, particularly the Triple Bottom Line (TBL) concept, the research explored challenges and considerations within local government in pursuit of sustainability in water infrastructure development. Utilising a qualitative research approach within a post-positivism paradigm, the study employed semi-structured interviews and document analysis as primary data collection methods, emphasising triangulation for research validity and ethical considerations throughout the study. Although the initially planned sample size was 12 participants, the study successfully interviewed seven municipal officials from ORTDM’s water and sanitation services delivery department, achieving a participation rate of 58%, which aligns with qualitative research standards. Findings from document analysis and interviews were categorised based on identified sustainability principles, highlighting strategies adopted and challenges encountered by ORTDM, including opportunities available for ORTDM. The study reveals that while ORTDM has made efforts to integrate sustainability principles, numerous challenges, including financial and natural resource constraints, organisational capacity limitations, inadequate infrastructure planning and maintenance, and socio-economic challenges, have hindered desired outcomes. Additionally, issues like vandalism, theft, biodiversity loss, and fragmented water conservation strategies exacerbate sustainability integration challenges. To address these barriers, the study recommends prioritising management approaches to enhance sustainability integration in ORTDM’s water services. Drawing on resilience theory, the study further proposes integrating resilience principles into planning, design, and management processes to improve organisational and system resilience, thus ensuring reliable and sustainable water services. The study emphasises the importance of interdisciplinary collaboration and innovative solutions in achieving resilient, equitable, economical, and environmentally responsible water supply distribution systems. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2024

- Description: Ecosystem degradation is a serious concern globally, including in South Africa, because of the potential adverse impacts on food security, livelihoods, climate change, biodiversity, and ecosystem services. Ecosystem degradation can result in flow alteration in the landscape through changes in the hydrological regime. The study adopts the South African National Biodiversity Institute (SANBI) Framework of Investing in Ecological Infrastructure (EI) to prioritise the restoration of degraded ecosystems and maintain ecosystem structures and functions. This study aims to assess how EI (specifically wetlands, grassland, abandoned cultivated fields, and riparian zone) can facilitate drought mitigation: to assess land degradation status and identify priority EI areas that can be restored to improve the drought mitigation capacity. Two assessment methods were used in this study. Firstly, the Trends.Earth tool was used to assess degradation and land cover change from the year 2000-2015 in Tsitsa catchment, through assessment of Sustainable Development Goal degradation indicator (SDG15.3.1) at a resolution of 300 m. The degradation indicator uses information from three sub-indicators: Productivity, Landcover and Soil Organic Carbon to compute degraded areas. The degraded areas need to be restored and rehabilitated to maintain the flow of essential ecosystems services provided by EI. The second assessment used the Analytical Hierarchy Process (AHP), which integrates stakeholder inputs into a multi-criteria decision analysis (MCDA). The AHP is a useful decision support system that considers a range of quantitative and qualitative alternatives in making a final decision to solve complex problems. As part of the AHP analysis, participatory mapping using Participatory Geographic Information System was conducted to obtain stakeholder inputs for prioritising restoration of the key EI categories (wetlands, grassland, abandoned cultivated fields, and riparian zone) in the catchment. During the participatory mapping, communities prioritised the key EI based on three criteria: (1) ecosystem health, (2) water provisioning and (3) social benefits. The AHP method was used in ArcGIS to prioritise suitable key EI restoration areas with high potential to increase water recharge and storage, contribute to drought mitigation and ecosystem services for the catchment. The prioritisation of EI for community livelihoods in the AHP analysis included all three main criteria. In comparison, the prioritisation of suitable key EI restoration areas for flow regulations was based on two criteria: ecosystem health and water provisioning. The land degradation indicator showed that approximately 54% of the catchment is stable, 41% is degraded land, and 5% of the area has improved over the assessment period (15 years). The degradation status in the EI suggests that more than half (>50%) of each EI category is stable, but there are areas showing signs of degradation, including 43% of grasslands degraded and 39% of wetlands, cultivated lands, and riparian zones also degraded. Degradation is dominant in the upper (T35B and T3C) and lower (T35K, T35L and T35M) parts of the catchments. The three criteria used by the stakeholders in the prioritisation process of the key EI were assigned 12 spatial attributes (the catchment characteristics about the study area in relation to the criteria) to indicate relevant information needed for selecting suitable restoration areas to enhance flow regulation. The AHP analysis results identified approximately 63% (17,703 ha) of wetlands, 88% (235,829 ha) of grasslands, 78% (13,608 ha) of abandoned cultivated fields and 93% (3,791 ha) of the riparian zones as suitable areas for restoration to mitigate drought impact through flow regulation. Also, the suitability results showed 63% (17,703 ha) of wetlands, 58% (2,203 ha) of riparian zones, 68% (11,745 ha) of abandoned cultivated fields and 46% (122,285 ha) of grasslands as suitable restoration areas for improving ecosystem services for community livelihoods. The AHP analysis identified more than 39-43% (of the degraded EI indicated by the Trends.Earth analysis) areas that are suitable for restoration, because key EI plays a significant role in flow regulation and people’s livelihoods, especially when they are managed, maintained, and restored to good health conditions. Therefore, the prioritized EI areas should be either maintained, managed, rehabilitated or restored. The major distinct causes of land degradation are woody encroachment in grasslands, invasion of alien plants on abandoned cultivated fields and soil erosion in the catchment. The most suitable EI areas recommended for restoration are those natural resources near local communities, which provide essential ecosystem services to sustain their livelihood. Therefore, degraded EI in the T35 catchments should be restored and maintained to improve livelihood and mitigate drought impacts. The study pointed out how the key selected ecological infrastructure can help mitigate the impacts of droughts and improve human livelihood. The study contributes towards the important concept of investing in ecological infrastructure to improve the social, environmental, and economic benefits. , Thesis (MSc) -- Faculty of Science, Institute for Water Research, 2022
