Many low-income developing countries struggle with waste collection and the development of disposal facilities, leading to issues such as illegal dumping and poor enforcement of waste management regulations. The pollution caused by street vendors' waste is particularly evident in the central business districts of cities in developing nations. The informal economy, which includes activities such as street vending has become prevalent in developing countries, particularly in Sub-Saharan African (SSA) nations. This study aims to conduct a systematic review and meta-analysis of existing literature on street vendors' waste management practices in the region, with a focus on understanding the factors influencing waste mismanagement and identifying integrated strategies employed across SSA. In most SSA areas, research is conducted to evaluate food vendor hygienic practices (33%), however the waste management component, which is crucial to hygiene, makes up just 15%, which is twice as small as the research that focused on hygienic practices. As a result, street vendors in the majority of sub-Saharan nations have little interest in waste management procedures. Many street vendors in the region resort to informal waste disposal methods because of no access to formal waste management infrastructure since they are not recognised as formal businesses. The study acknowledges the street vendors' contribution to food security in developing Sub Saharan Africa, as well as the significance of comprehending their waste management practices. Despite their prevalence in urban areas, these informal businesses still face a lack of recognition and inclusion from governing bodies. Therefore, the study emphasises the necessity of incorporating street vendors into formal municipal waste management systems and providing them with enhanced infrastructure and services. Given that the lack of recognition subsequently make it challenging to integrate vendors into formal waste management systems. Subsequently this has a negative cumulative impact on developing and enforcing clear regulations that specify the responsibilities of street vendors in waste management. Thus, leading to the absence of comprehensive by laws regulations governing waste management for street vendors within Sub-Saharan Africa.

Illegal disposal of solid waste is a significant issue in many parts of the world, particularly in urban areas. Because of unprecedented urbanization, these areas are crowded, putting pressure on the already inadequate municipal services such as waste management. As municipalities fail to provide adequate and effective waste management services, the expansion and proliferation of informal settlements contribute to the problem of illegal dumping. Apartheid spatial planning produced environmentally unsustainable cities characterized by glaring disparities in municipal resource allocation, disturbingly inefficient transportation systems, and widespread urban insecurity. Therefore, this study examines how the expansion of informal settlement at an unprecedented rate contributes to illegal dumping post-apartheid by conducting a systematic review. Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, a literature search from 1994 to 2023 was conducted in the field of waste management. The review focuses on three key aspects: (1) factors that contribute to illegal dumping in townships; (2) waste management laws during apartheid and post apartheid; and (3) waste collection system in townships and spatial planning. South Africa’s inequality is a major contributor to environmental degradation. The situation was exacerbated by efforts to prevent urban migration and forcefully remove black people from cities; apartheid ideology justified the dormitory-like nature of urban townships. In the South African context, the literature reveals that there is a research gap in the application of technologies and effective waste management plans to keep up with the growing number of informal settlements. Furthermore, despite progressive environmental policies, implementation has been ineffective. This study offers valuable evidence on the spatial and temporal dynamics of informal settlements, addressing both the location and time aspects. A robust government-led Community Participation in Solid Waste Management program is required immediately.

In Africa, the legacy of mining has not only contributed to economic growth, employment, and prosperity but also brought risks to pollution exposure associated with detrimental health effects, ecological degradation, and social upheaval, such as the rapid Zama-Zamas. Due to this, illegal mining on the African continent has numerous environmental implications. While illegal mining operations have an adverse impact on the environment, government and academic research into the Zama-Zamas in South Africa has focused mainly on the socio-economic aspects of the illegal mining aspect, so environmental factors have been overlooked. Most government reports and academic literature on illegal mining activities in the country typically emphasize the socio-economic impact with little or no environmental consideration. Zama-Zamas have a major socioeconomic impact; however, their adverse impact on the environment cannot be ignored as well. This is especially true with Zama-Zamas’ illegal activities, which result in environmental pollution that may affect the entire ecosystem as a result. Based on this background, the purpose of this paper is to explore the significant environmental implications of Zama-Zama’s illegal mining in the South African context. The current study has discovered that there is little documentation regarding the environmental implications of illegal mining within communities where it occurs within South Africa’s mining sector, despite its infiltration by Zama-Zamas illegal mining activities. This is a cause for concern, especially within countries like South Africa where illegal mining has become a national crisis, yet the environmental impacts of illegal mining from the literature point of view are not well documented. The limited literature on this issue highlights the need for urgent attention to the environmental damage caused by illegal mining. Thus, this appraisal advocates for the inclusion of environmental impact studies alongside the socio-economic impacts widely reported on illegal mining. For a country striving to achieve sustainable development, understanding the holistic potential risks of illegal mining activities by Zama-Zama is essential.

The quality of education is significantly influenced by occupational health and safety (OHS) measures. To this end, a safety incident at a university could have far-reaching negative effects on facilitating teaching and learning for both lecturers and students. Although OHS standards are widely established in numerous industries, they are often overlooked in the academic setting. It is for this reason that, to date, research gap exists in OHS systems in academic settings. While universities primarily focus on education, they also pose significant health and safety risks to staff and students due to their design and setup. Effective implementation of an occupational health and safety management system (OHSMS) within universities can mitigate these risks. However, there is a notable lack of research focusing on the efficiency of OHSMS in South African universities. This study, therefore, aimed to fill this gap by assessing the efficiency of the OHSMS at a South African university. Data were collected using in-depth interviews, observations, and document analysis qualitative research methods. Data analysis was carried out using the thematic analysis approach. Inductive logic was used in the interpretation of the current study results. This study highlights that while there is strong awareness of the OHS Act 85 of 1993 (>90%) among university staff, significant gaps exist in the communication and enforcement (5%) of OHS policy, alongside the poor communication of hazards and risks (30%). Amongst other challenges are infrastructure maintenance (>35%), as well as the lack of standard operation procedures (>5%). To address some of these setbacks, the current study recommends enhancing policy communication, conducting regular hazard assessments, increasing training participation, and improving documentation practices. These steps aim to improve the efficiency and effectiveness of the university’s OHSMS, ensuring a safer environment for all stakeholders.

Water quality problems are a major challenge that humans encounter in the 21st Century. Water security presents a pressing concern in South Africa due to persistent difficulties in ensuring water availability, accessibility, and quality. Given the numerous activities that are taking place adjacent to riverbanks, there has been a decline in water quality. This study determined the state of the Crocodile River’s intermediate water quality and assessed the effects of various human-induced activities. Water samples were collected during 2016–2023 in different sites within the Crocodile River, and physicochemical parameters were analysed in an accredited laboratory. The Python package Seaborn was used for statistical analysis of the data to provide visualizations and data variations. Overall, the results show that elevated concentrations of electrical conductivity (EC) and sulphate (SO₄²⁻) were recorded in the Crocodile River. The presence of elevated EC levels in R571 Bridge exceeded 133.90 µs/cm between 2020 and 2021, whilst the highest concentration levels (114 mg/L) for SO₄²⁻ were recorded in Malelane in the year 2020. The elevated concentrations of concern were recorded during the dry season (winter) and the wet season (spring). Overall, the comparisons of the spatiotemporal concentration indicate that the water quality parameters fluctuate over time. Moreover, the monitoring practice of detecting the water quality change over time is also fundamental for providing valuable information necessary for the management of integrated water resources.

The integration of indigenous knowledge systems into the discussion of bush encroachment management is of paramount importance. Indigenous knowledge and formal monitoring may be mutually beneficial, and using both approaches can improve natural resource management. Savannah rangeland landscapes hold deep cultural and spiritual significance for indigenous communities, and their perceptions can provide valuable insights into creating more effective, community-driven conservation initiatives. This study was aimed at filling the existing knowledge and research gap on bush encroachment control by focusing on the integration of indigenous knowledge systems. To achieve this, the current research included three distinct non-probability sampling strategies: (1) Purposive, (2) Snowball, (3) Convenience sampling methods. The results showed that 90.3% of the participants indicated that the main encroaching species of concern was sickle bush (Dichrostachys cinerea) and it is therefore perceived as a problem in the rangeland. The majority of farmer respondents indicated that they cut the encroacher plant down, uproot all root systems, then burn the remaining roots. This is reported to be a more effective way of managing sickle bush as an encroacher plant. Both genders generally believe in the efficacy of these systems, with variations in levels of agreement. However, a gender disparity emerges in opinions on incorporating communal-based approaches, emphasizing the need to consider gender perspectives in environmental management initiatives. Therefore, considering this, the study concludes that a holistic approach, integrating both formal and informal knowledge systems, may be crucial for sustainable and effective management strategies. Given that, recognizing the diversity of perspectives within the community, particularly regarding gender differences, is essential for developing inclusive and community-driven environmental management initiatives.
