Sustainability of South African Hpmestays: an integrated approach for Tourism and Hospitality Development

(2025-05-16) Nethengwe, Tondani; Dafuleya, G.; Mokabe, M.

This study aimed to develop a framework for enhancing the sustainability of homestays in South Africa, addressing the lack of standardized quality control and certification programs. This absence leads to inconsistent service quality, making it difficult for tourists to set clear expectations. The research assessed the current state of homestays by profiling various types through online surveys, including web pages and social media platforms like Facebook. A case study approach was used to evaluate the economic, environmental, and social factors influencing homestay sustainability. Six homestays (two per province—urban and rural) across three provinces (Limpopo, Mpumalanga, and KwaZulu-Natal) were selected for in-depth interviews. Surveys were conducted with 120 households near each homestay to examine local community perceptions. The findings revealed the need for government intervention to establish clear policies for regulating homestay standards. This would address inconsistencies and improve service quality and sustainability. The study also emphasized the importance of adopting responsible environmental practices, such as solar energy, sustainable water management, and better waste disposal systems, to mitigate long-term environmental damage. It recommended training programs to encourage sustainable tourism practices among homestay operators. The research further identified the vulnerability of homestays to climate change, particularly in rural, ecologically sensitive areas. Strategies to enhance climate resilience, such as eco-friendly infrastructure and disaster preparedness, were suggested. Additionally, technological challenges were identified, particularly in rural areas where limited access to digital platforms restricts marketing efforts. The study recommended capacity-building initiatives to improve the visibility and profitability of homestays through digital marketing and online platforms. Regarding community perceptions, the study found that local communities generally viewed homestays positively, with no major social or economic changes observed. However, the study suggests further research, including structured surveys targeting various community groups, to assess the broader impacts of homestays on the economy, society, and environment.

Developing guidelines for the protection of indigeneous knowledge under agreement establishing the African Continental Free Trade Area

(2025-05-16) Mukwevho, Tshimangadzo Donald; Ndlovu, L.; Oriakhogba, D. O.

This study examines the efficacy of protecting indigenous knowledge within the context of the African Continental Free Trade Area (AfCFTA) Agreement. It examines the efforts aimed at establishing a robust legal and policy framework within the AfCFTA to foster African economic development. Although the Protocol to the Agreement Establishing the African Continental Free Trade Area on Intellectual Property Rights (IP Protocol) has been adopted, there is yet to be an annex on indigenous knowledge, traditional cultural expressions, and genetic resources. Therefore, this study proposes guidelines and a structured framework to guide the development of this annex. As a desktop (doctrinal) research, this study examines international, regional, and national legal frameworks, best practices, case law, and academic literature on the protection of indigenous knowledge. Grounded in a combined biopiracy, IP, and, free, prior, and informed consent (FPIC) conceptual framework, this study develops an "Integrated Indigenous Knowledge Protection Theory," which justifies the adaptation of the conventional IP regimes and developing a sui generis regime for indigenous knowledge protection. This approach encapsulates the incorporation of the IP regime, indigenous peoples’ rights, customary rules, and administrative and institutional framework for protecting indigenous knowledge. To achieve the study objectives, the thesis explores the propriety of using trade agreements, particularly the AfCFTA Agreement, to protect indigenous knowledge. It then examines the approaches adopted in existing international and national legal, policy and practices on the protection of indigenous knowledge. From this, the study proposes useful guidelines and effective structure for the Annex to the IP Protocol. Ultimately, this study advances the argument that a comprehensive framework that balances the economic exploitation of indigenous knowledge and the associated resources, with the rights indigenous people/communities have over these resources will effectively guide policy and lawmakers towards developing a framework that will ensure the protection of indigenous knowledge for the actualisation of the objectives of the AfCFTA Agreement.

Impacts of seasonal dynamics on cyanobacterial proliferation and cyanotoxins bioaccumulation in fish species: Comparative study of aquaculture fishponds in Nigeria and South Africa

(2025-05-16) Bassey, Odo Jones; Gumbo, Jabulani; Mujuru, M.; Dondofema, F.

Aquaculture production plays a pivotal role in advancing Sustainable Development Goals (SDGs), particularly those focused on food security, economic growth, livelihoods, sustainable production, biodiversity conservation, and improved nutrition. Locally produced fish from aquaculture ponds serve as an affordable and accessible protein source in countries like Nigeria and South Africa. However, the rise of cyanobacterial harmful algal blooms (CyanoHABs) poses a serious challenge to the sustainability of fish culture production and human health. In the aquaculture ecosystem, the consequences of these blooms have triggered widespread interest due to cyanotoxin bioaccumulation in cultured fish species. In tropical regions, especially in Africa, there is a paucity of research investigating the temporal drivers of cyanobacterial biomass in aquaculture fishponds. Cyanobacteria are integral to the pond food chain, yet their seasonal dynamics factors and influencing factors remain poorly understood. This knowledge gap is particularly critical as these factors significantly impact aquaculture productivity and the risks associated with cyanobacterial blooms. Therefore, this study investigated the impact of seasonal dynamics on cyanobacterial proliferation and cyanotoxin bioaccumulation in cultured fish. A comparative study design between small-scale commercial fishponds located in Nigeria (NGA) and South Africa was employed in this study. A total of six fishponds located in Calabar Municipality, Cross River State, Nigeria, and Duthuni, Vhembe District, Limpopo Province, South Africa (SA), were selected. Water and Clarias gariepinus (African catfish) samples were collected from each fishpond at seasonal intervals (SA - summer, winter, NGA - dry and wet seasons). Seasonal variations in water quality parameters were observed in NGA and SA fishponds. Cyanotoxins analysis was carried out using the Liquid Chromatography-Mass Spectrometry (LCMS). The results of the study revealed that elevated temperatures (>20°C) were consistent during dry, wet, and summer seasons, with a notable winter decrease (16.5°C) at Duthuni, South Africa. Dissolved oxygen (DO) and electrical conductivity (EC) levels were consistently low across seasons, while total dissolved solids (TDS) peaked during winter in South Africa (125–193.2 mg/L) and were lower in Nigeria (15.9–37.7 mg/L). Nutrients, particularly nitrite and nitrate, peaked in Nigeria during wet (10.42 mg/L) and dry (6.45 mg/L) seasons, while South African fishponds exhibited lower concentrations in both summer and winter. The study revealed that cyanobacterial biomass and cyanotoxins in fishponds were not driven by seasonal factors like warmer temperatures or precipitation. Cyanobacteria biomass was predominantly influenced by management practices, including feeding, fertilization, nutrient levels, water volume, stocking density, water exchange, and retention time. The LCMS analysis revealed that the microcystin variant MC-RR was absent in fish tissue, while MC-YR was detected in the intestines, gills, muscles, and liver. The highest concentration of 20.9 μg/g was found in the liver. Additionally, untargeted LC-MS identified a broader range of cyanotoxins, including aeruginosins, anabaenopeptins, microcystins, and microginins, in the water samples and fish tissue. These findings underscore the critical influence of fishpond management practices on cyanobacterial dynamics and cyanotoxin bioaccumulation. This study highlights the need for targeted interventions to mitigate cyanotoxins risks in aquaculture systems. Understanding and addressing these factors are essential for ensuring the sustainability of aquaculture production and safeguarding public health in tropical regions.

Investigating the effects of aridity and its impacts on water resources availability in the Luvuvhu River Catchment

(2025-06-16) Nkuna, Tinyiko Rivers; Makungo, R.

The study investigated aridity and its impacts on water resource availability in the Luvuvhu River Catchment (LRC). Hydrological information indicates gradual changes towards more arid conditions in the LRC. The shift towards aridity has impacted negatively on water resources availability. Aridity indices for the LRC were determined using both meteorological and hydrological data. The 5-year or 10-year rainfall or streamflow averages were used to detect drought thresholds, except during flood events. A significant study was done on drought conditions using Standardised Precipitation Index (SPI), Standardised Precipitation-Evapotranspiration (SPEI) and Standardised Streamflow Index (SDI). The study hypothesised increased inter-station variations (spatial and temporal) observable from 5-year or 10-year rainfall or streamflow averages over a historical hydrological period. The study used rainfall and temperature data from the Agricultural Research Council (ARC) and South African Weather Service (SAWS) spanning 58 years (1961 - 2018). National Centers for Environmental Prediction (NCEP) data with a resolution of 10 km was used to determine historical and future aridity in the LRC. The spatiotemporal variations and trends of aridity are reflected in the availability and distribution of water resources. The study developed the aridity indices using United Nations Environment Programme (UNEP) Aridity Index (AI) to determine the spatiotemporal variability of water resources in the LRC. The variations and trends of aridity indices were determined using the coefficient of variation and Mann Kendall test, respectively. Due to a limited number of weather stations in the study area, the Kriging method was used to interpolate aridity indices for areas with no stations. The temporal changes of the 5-year or 10-year cycles of hydrological data analyses show progressive, gradual increases linked to global environmental changes such as global warming. The Hierarchical clustering (HC) analysis revealed the presence of two factors that account for 59.7% and 39.3% of the variability in rainfall within the LRC. The results show that upstream of the catchment experiences more rainfall and lower temperatures than downstream. The increase in temperature and decrease in rainfall might negatively impact the availability of water resources for downstream users. Thus, more arid conditions are experienced downstream of the catchment than upstream. Flood events have become rare and more intense, a characteristic associated with areas prone to droughts. The results of the study reveal significant year-to-year variability in floods and drought events. The increase in aridity should be considered when allocating water resources and implementing sustainable water resources management in the LRC. Thus, the study provides a baseline for monitoring and modelling hydrological processes in arid environments.

Evaluation of public participation process in environmental impact assessments of selected development projects in the Vhembe District of South Africa

(2025-05-16) Magosha, Tendani Amos; Nethengwe, N. S.; Mudau, N. V.

Ensuring a pragmatic balance between environmental imperatives and community development within Vhembe district in South Africa has been a growing concern since communities’ right to an environment that sustains their wellbeing is being infringed due to ecologically unsustainable development activities carried out in the area. In the wake of this, this research study evaluated the extent to which Environmental Impact Assessments (EIAs) of development projects in Vhembe district complied with public participation as stipulated by EIA policy guidelines and goals provided within EIA legislation in South Africa. The objectives of the study were: to evaluate the level of awareness of guidelines for public participation by the community; to assess the extent to which Environmental Assessment Practitioners (EAPs) have complied with guidelines for public participation in EIA legislations; and to assess public participation practice by EAPs in relation to community expectations in Vhembe district. This study relied mainly on qualitative method of data collection and analysis supplemented by quantitative method. In order to achieve the main aim of this research, a case study was used. Simple random sampling method was done on development projects that required EIA due to their potential to cause irreversible harm to the Earth’s systems thus undermine sustainable development. These development projects were sampled from the four local municipalities within Vhembe district. Systematic sampling was used to identify respondents to whom questionnaires were administered. Interviews were conducted with twelve key informants and also with four EAPs who conducted EIAs for the sampled development projects. The reviewed documents for the development projects included Basic Assessment Reports (BARs); and Scoping and Environmental Impact Report (S&EIR). For data analysis, Statistical Packages for the Social Sciences (SPSS) was used. The results revealed that community members are generally not conversant with EIA guidelines for public participation. Furthermore, it was revealed that EAPs only complied with some of the minimum requirements of EIA procedure. Also notable is that EAPs displayed lack of requisite expertise on how to conduct public participation and as a result infringed on the public’s right to access information by making projects’ information only available in libraries and websites. Key recommendation is that public participation should be made effective and participative by ensuring that community members are capacitated accordingly. As a key contribution to the body of knowledge, this study developed a context-based adaptive strategic framework for ensuring effective and participative public participation practice based on local realities thus to ensure sustainable development.
