Due to climate change's effects, protected areas, particularly national parks, face conservation challenges, negatively impacting tourism. Sustainable tourism requires understanding the climate and conservation challenges in national parks and their implications for tourism. Marakele National Park in South Africa faces climatic and conservation challenges. A purposive and snowball sampling strategy was used to select study participants. An in-depth interview was conducted with the employees of South African National Parks, including top managers, scientists, field, section, honorary rangers, conservationists, and hospitality staff. A perception survey involving 871 tourists was conducted along with field observations, archival data, and an analysis of archival data. The study results indicate that rainfall levels in the national park vary greatly from season to season and are declining. A warm climate and high rainfall were also observed, and increased drought episodes. The observed climatic extremes led to several ecological challenges, including bush thickening and encroachment, intense soil erosion, wetland degradation and an increased frequency of wildfires. The environmental challenges impact the park's aesthetic value, affect tourist comfort and perceptions, and cause employee discomfort. The paper recommends that the park develops anticipatory action plans for the identified climatic and tourist attraction risks. [ABSTRACT FROM AUTHOR]

The emerging economies of Brazil, Russia, India, China and South Africa (BRICS) have significant influence on the global economic and environmental trajectories. They have carbon intensive economic systems, which contribute significantly to total global greenhouse gas (GHG) emissions, leading to climate change. However, BRICS have joined the race to net-zero emissions by 2050 in the quest for a climate neutral and sustainable global economy. The journey, however, is not without challenges and opportunities. The proliferation of the coronavirus disease 2019 (COVID-19) had mixed reactions from scientists regarding its implications on net-zero trajectories. While statistical data show a correlation between COVID-19 and a decrease in total emissions, it is envisaged that COVID-19 compromised the efforts to develop carbon neutral economies. Hence, there is still need for more scientific examination of COVID-19's impact on net-zero ambitions, especially in the emerging economies. This study focuses on India and South Africa's trajectories. Statistical analysis of secondary data from authentic interactive web-based dashboards for COVID-19 data repositories, namely Our World in Data and Climate Action Tracker was performed in conjunction with the document analysis approach following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Some of the COVID-19 challenges as indicated by the results of the study include curtailing the technology transfer staircase in the energy sector, retaliatory emissions for recovery and resource diversion. The opportunities presented by COVID-19 in the quest for carbon neutrality include behavioural changes in investment, production and consumption patterns with a focus on low carbon options. Governments and stakeholders need to focus on addressing the barriers whilst riding on the opportunities presented by the pandemic to achieve net-zero emissions by 2050. [ABSTRACT FROM AUTHOR]

[Display omitted] • The pandemic did not halt, nor slow down climate change. • Africa faces challenges in financing climate action. • COVID-19 drained resources and attention for climate action. • Africa will be less sustainable and resilient post-COVID-19. • Approaches used to address COVID-19 should be adopted for climate change. This study assesses the potential for establishing a sustainable and climate-resilient African economy, post-COVID-19, focusing on Kenya, South Africa, Rwanda, and Zimbabwe. Utilising the United Nation's Climate-Positive Action Framework, document analysis, and a systematic literature review, it examines these nations' investment in climate action. Findings reveal a decrease in climate funding during the pandemic, with notable gaps in climate finance, including reallocations away from climate-related ministries and delays in project implementation. This decline in climate action poses risks to sustainability and climate resilience. To mitigate these risks, the study emphasizes the need for frameworks to mobilize external and domestic resources for climate action. Despite ongoing challenges posed by COVID-19, proactive measures are essential to maintain focus on climate action. [ABSTRACT FROM AUTHOR]

This study examined the impact of climate change on plant species diversity of a savanna ecosystem, through an assessment of climatic trends over a period of forty years (1974–2014) using Masvingo Province, Zimbabwe, as a case study. The normalised difference vegetation index (NDVI) was used as a proxy for plant species diversity to cover for the absence of long-term historical plant diversity data. Observed precipitation and temperature data collected over the review period were compared with the trends in NDVI to understand the impact of climate change on plant species diversity over time. The nonaligned block sampling design was used as the sampling framework, from which 198 sampling plots were identified. Data sources included satellite images, field measurements, and direct observations. Temperature and precipitation had significant (p < 0.05) trends over the period under study. However, the trend for seasonal total precipitation was not significant but declining. Significant correlations (p < 0.001) were identified between various climate variables and the Shannon index of diversity. NDVI was also significantly correlated to the Shannon index of diversity. The declining trend of plant species in savanna ecosystems is directly linked to the decreasing precipitation and increasing temperatures. [ABSTRACT FROM AUTHOR]
