(Elsevier, 2025-05) Patrick, Sean Mark; Shirinde, Joyce; Kgarosi, Kabelo; Makinthisa, Takalani; Euripidou, Rico; Munnik, Victor; sean.patrick@up.ac.za
BACKGROUND : South Africa’s just energy transition (JET) aims to reduce coal dependency and shift toward a low-carbon, sustainable energy framework. However, achieving this goal requires addressing the socio-economic, health, and environmental burdens that coal dependency has placed on communities, particularly in regions like Mpumalanga. Integrating principles of social and restorative justice is essential to ensure an equitable transition.
OBJECTIVE : This scoping review examine how South Africa's policymaking, regulatory frameworks, and public participation in the JET align with principles of social and restorative justice and global energy transition frameworks.
METHODS : A systematic literature search was conducted across Scopus, Web of Science, and PubMed to identify relevant studies on energy transition and justice frameworks. Network analysis was employed to compare South Africa’s JET strategies with global trends, focusing on indicators related to health, environmental, and socio-economic impacts.
RESULTS : Findings reveal significant challenges in South Africa’s JET, including regulatory limitations, stakeholder conflicts, and gaps in policy alignment with community needs. Although efforts to incorporate justice principles are emerging, disparities in policy implementation suggest the need for more tailored, inclusive approaches. Network analysis identified both overlaps and gaps between South Africa’s JET policies and international frameworks, particularly in areas of public health and social equity.
CONCLUSION : To achieve a balanced and inclusive energy transition, the study recommends strengthening regulatory coherence, enhancing public engagement, and implementing concrete actions for social and restorative justice. Aligning domestic policies with international commitments while addressing local socio-economic conditions is critical for South Africa’s JET to serve as a model for coal-dependent economies globally.
'New mining scheme, same old problems?' ; risk factors and health challenges in underground community mining in Ghana
(IOP Publishing, 2024-12) Aram, Simon Appah; Saalidong, Benjamin M.; Yankyera, Akwasi; Akoto, Akwasi Bamfo; Amoah, Samuel Kofi
Ghana's small-scale mining sector has long been a cornerstone of its economy and a vital source of livelihood for many communities. However, the sector is plagued by significant challenges, including environmental degradation, health and safety risks, and illegal practices. In response, the Ghanaian government introduced the Community Mining Scheme (CMS), a new mining model designed to promote local community participation in artisanal small-scale gold mining (ASGM). This study examines the workplace risk factors and associated health challenges faced by ASGM miners under the CMS, drawing on interviews with fifty underground CMS miners in Ghana. Our findings reveal that miners continue to face numerous health and safety challenges, including inadequate lighting, poor ventilation, exposure to noise and odors, unsupported or poorly supported loose materials, non-use of personal protective equipment, high dust levels, and unsafe blasting practices. Additionally, health concerns such as skin rashes, musculoskeletal injuries, and the risk of mercury poisoning persist. These challenges mirror those reported in the literature on unregulated and illegal ASGM in Ghana, indicating that existing issues remain unresolved under the CMS. To prevent the undermining of this initiative, it is crucial to adopt progressive practices, such as localized coping strategies and the recruitment of trained professionals to lead ASGM operations within the CMS. Enhancing miners' risk perception through targeted outreach and awareness campaigns is also essential. Further recommendations for mitigating safety risks and health challenges are discussed in the article.
Historical catch records of humpback whales and the assessment of early 20th century sea ice edge in climate models
(IOP Publishing, 2025-05) Vichi, Marcello; Seyboth, Elisa; Mazomba,Thando; Vermeulen, Els; Findlay, Ken; Meynecke, Jan-Olaf; De Bie, Jasper; Secchi, Eduardo; Dalla Rosa, Luciano; Roychoudhury, Alakendra
Assessment of historical environmental conditions in the Southern Ocean is limited by sparse oceanographic records prior to remote-sensing data. Whale catch data, particularly from humpback whales, can help fill this gap, as these whales inhabit waters near the sea ice edge. This study combines historical whale catch data with sea-ice model simulations from CMIP6 to assess the performance in the decade 1930–1939. The models were ranked based on their ability to simulate satellite-observed sea ice seasonality. The high-ranking models locate the sea-ice edge north of historical humpback whale catch regions, indicating higher sea-ice extent at the start of the 20th century, especially in November and December. It is recommended that models be tuned towards these early 20th century conditions while running the pre-industrial simulations. This interdisciplinary approach suggests that using only satellite-era data for model calibration may lead to overestimates of historical sea-ice extent, affecting future predictions.
Megagrazer loss drives complex landscape-scale biophysical cascades
(IOP Publishing, 2025-01) Hyvarinen, Olli; Te Beest, Mariska; Le Roux, Elizabeth; Kerley, Graham I.H.; Buitenwerf, Robert; Druce, Dave J.; Chen, Jiquan; Rapp, Linda; Fernandes, Joana; Cromsigt, Joris P.G.M.
Wild animals can modulate ecosystem-climate feedbacks, e.g. through impacts on vegetation and associated carbon dynamics. However, vegetation cover and composition also affect land surface albedo, which is an important component of the global energy budget. We currently know very little about the influence of wild animals on land surface albedo and the resulting climate forcing of these albedo changes. Leveraging a unique, ecosystem-scale, semi-experimental approach, we study how the local removals of the world's largest, terrestrial grazer, white rhinoceros (Ceratotherium simum), affected the coupling between fire dynamics, woody encroachment and surface albedo in Hluhluwe–iMfolozi Park (HiP), South Africa. Our path analysis revealed that areas in the park where more rhinos had been removed showed a stronger increase in burnt area and woody encroachment compared to areas with fewer rhinos removed, which were both related to a decrease in surface albedo. Increasing burnt area was further associated with higher rates of woody encroachment, indirectly reinforcing the negative effect of rhino loss on albedo. Our study demonstrates that removals of megagrazers in HiP were related to complex ecosystem-wide cascades with measurable impacts on land cover and surface albedo and consequences on climate forcing. This highlights the importance of restoring functional ecosystems by reinstating trophic processes.
Building volume per capita : a crowding metric of housing disparities in Gauteng, South Africa
(Sage, 2025) Naidoo, Laven; Ballard, Richard; Naidoo, Yashena; Maree, Gillian; Khanyile, Samkelisiwe; Palacios-Lopez, Daniela; Esch, Thomas
In South Africa’s largest city region, located in the province of Gauteng, a key condition of inequality is that high-income households live in large houses while low-income households live in much smaller accommodation. Innovations in earth observation have enabled the modelling of building volumes in cities and this allows for new ways of assessing housing inequalities in Gauteng. This study calculates building volume per capita (BVPC) for the province as an indication of the volume of residential space in which individuals live. It offers five analyses using this data. First, mapping this metric illustrates that townships, informal settlements and inner city high-rise areas have cramped conditions of less than 10 cubic metres per person, while suburbs have a much higher building volume per capita. Second, the article shows that this metric complements traditional calculations of crowding, such as the number of people per room. Third, it calculates the relationship between BVPC and income and shows that the lower-earning three-fifths of households in the province occupy just 13% of the province’s residential building volume, while the higher-earning two-fifths occupy 87% of the province’s building volume. Fourth, it calculates that 51% of residential hexagons in the province fall below the threshold of adequately sized housing as defined by South African housing standards. Finally, it shows that areas that fall below the threshold have a higher proportion of informal housing.
