Evapotranspiration (ET) is crucial to the management of water supplies and the functioning of numerous terrestrial ecosystems. To understand and propose planning strategies for water-resource and crop management, it is critical to examine the geo-temporal patterns of ET in drought-prone areas such as the Upper Orange River Basin (UORB) in South Africa. While information on ET changes is computed from directly observed parameters, capturing it through remote sensing is inexpensive, consistent, and feasible at different space–time scales. Here, we employed the Moderate Resolution Imaging Spectroradiometer (MODIS)-derived spectral indices within Google Earth Engine (GEE) to analyze and characterize patterns of ET over the UORB from 2003 to 2021, in association with various climatic parameters. Our results show spatially consistent ET patterns with the Vegetation Condition Index (VCI), with lower values in the west, increasing toward the eastern section of the basin, over the Lesotho highlands. We noted that the UORB faced significant variability in ET and VCI during pronounced drought episodes. The random forests (RF) model identified precipitation, temperature, Standardized Precipitation Index (SPI)-6, Palmer Drought Severity Index (PDSI), and VCI as variables of high importance for ET variability, while the wavelet analysis confirmed the coherence connectivity between these variables with periodicities ranging from eight to 32 months, suggesting a strong causal influence on ET, except for PDSI, that showed an erratic relationship. Based on the sequential Mann–Kendall test, we concluded that evapotranspiration has exhibited a statistically downward trend since 2011, which was particularly pronounced during the dry periods in 2015–2016, 2019, and 2021. Our study also confirmed the high capacity of the GEE and MODIS-derived indices in mapping consistent geo-temporal ET patterns.

This review aims to explore the implications of climate change for breast cancer management and prevention, with a focus on global strategies and interventions that can be applied in various contexts, including South Africa. Climate change has emerged as a significant global health concern, with far-reaching implications for various diseases, including cancer. This systematic review aims to synthesise epidemiological research examining the relationship between climate change and the incidence of breast cancer. We conducted a comprehensive literature search using main search terms, including “breast cancer,” “climate change,” “air pollution,” “water pollution,” “global warming,” and “greenhouse effect,” supplemented by the general term “breast” cancer across multiple databases. Our analysis identified studies that link environmental changes—such as rising temperatures, altered precipitation patterns, and increased exposure to pollutants—with breast cancer risk. Our findings highlight a potential association between climate-related factors, including heat stress, air and water pollution, endocrine-disrupting chemicals, and lifestyle changes influenced by environmental shifts, and the epidemiology of breast cancer. This review underscores the need for an integrated approach that incorporates climate science into public health strategies to mitigate breast cancer risk. By elucidating these connections, we aim to inform policymakers and healthcare professionals about the importance of addressing climate change not just as an environmental issue, but as a pressing determinant of health that may exacerbate cancer incidence, particularly in vulnerable populations. Further research is warranted to elucidate the underlying biological mechanisms and to develop targeted interventions that can address both climate change and its potential health impacts.

Global biodiversity is declining at an alarming rate; however, evidence suggests that this decline occurs far more slowly on Indigenous-owned land. This can be attributed to cultural worldviews in which protecting nature and living in harmony with the environment are fundamental principles, an ethos central to African societies and many other Indigenous communities worldwide. This study examines the role of Vhavenda traditional belief systems, Indigenous knowledge, and cultural practices in the management and conservation of natural resources and the environment. In contemporary Limpopo Province, the Vhavenda clans of northern South Africa remain among the country’s most traditional communities, continuing rituals and practices that have been transmitted across generations. According to the 2022 national census, the area inhabited by the Vhavenda tribe, records the country’s highest concentration of centenarians, a demographic pattern which they attribute to the region’s cultural continuity and relative geographical isolation, which have enabled the preservation of its spiritual and ecological heritage. The research employed an insider ethnographic methodology, collecting data through personal interviews and a focus group discussion. Findings reveal that Indigenous beliefs, knowledge systems, and taboos play a substantial role in promoting sustainable land use. They restrict development on ecologically sensitive landscapes and discourage harmful practices, such as deforestation and cultivation along water bodies. These practices are enforced through complex customary laws, often articulated through prohibitive norms (“thou shalt not”), that safeguard plants, animals, water sources, and other natural resources. The study further illustrates that these prohibitions reflect a nuanced understanding of the biophysical environment, with the most sensitive and vulnerable ecosystems and ecologically important species, including keystone, foundation, and indicator species, receiving protection. Overall, the research shows the importance of recognising, protecting, and integrating Indigenous cultural systems as a critical component of effective biodiversity conservation.
