This study explores factors influencing female engagement in STEM (Science, Technology, Engineering, and Mathematics) fields in Mozambique, Nigeria, and Uganda through Urie Bronfenbrenner’s Ecological Systems Theory. The research collected qualitative data from 81 women across these countries through open-ended surveys. Using content analysis, the results demonstrate the critical role of personal interests nurtured by family, showing how direct interactions with family influence STEM engagement at a microsystem level. The mesosystem level reveals the supportive influence of community and school interactions, emphasizing the importance of relationships between different microsystems, such as family–school collaborations, in fostering female participation in STEM. The exosystem level identifies the impact of positive media portrayals and role models, illustrating how external environments indirectly affect perceptions and aspirations in STEM through media and societal influences. The macrosystem level underscores the persistent cultural norms shaping gender roles, reflecting broader societal and cultural values that influence gender diversity in STEM fields, with 63% of respondents in Mozambique, 57% in Nigeria, and 67% in Uganda indicating that societal views on gender roles discouraged participation. Lastly, the chronosystem level captures the temporal changes and progress in gender diversity in STEM, highlighting the need for targeted interventions and policy reforms to address longstanding gender imbalances. Despite progress, significant gender imbalances remain, necessitating targeted interventions and policy reforms. The study proposes a sustainable, collaborative model to foster early interest and sustained participation of females in STEM, emphasizing the importance of seamless cooperation among families, educational institutions, communities, and government bodies. The findings aid in creating supportive environments for sustaining female STEM participation, promoting economic and social development in Sub-Saharan Africa.

The impact of climate change has made weather events more extreme, unpredictable and frequent. In the last 4 years, Mozambique has been devastated by 8 major cyclones, resulting in material and human damage and affecting the functioning of basic local services, such as in the water and health sectors. In this study, we explored the environmental components of the climate–water quality–disease relationship that could drive the dynamics of waterborne diseases. Statistical models and geospatial information technologies (GITs) were used to analyse water quality and the relationship with waterborne diseases between 2016 and 2023. Results indicate that water quality is the main element, between precipitation natural disasters and waterborne diseases, on which a relevant public health intervention can act to ameliorate the future negative impacts of climate change and disease incidence. The results of this study also showed that the quality of water affected mainly by heavy rain events varies in different regions and in different seasons.

This article presents a systematic review of land-based marine pollution in the Southern African Development Community (SADC), focusing on the river–sea interface. Using the PRISMA protocol, 30 articles published between 2015 and 2025 were selected. Key pollutants identified include microplastics, nutrients, heavy metals, and urban effluents, which travel through river basins and impact coastal ecosystems and communities. The region faces serious challenges due to limited wastewater treatment coverage, with many urban areas lacking adequate infrastructure or using outdated technologies. This leads to widespread discharge of untreated effluents into rivers. Fragmented governance, weak institutional capacity, and insufficient implementation of regional treaties further hinder pollution control. Climate change exacerbates these pressures by increasing hydrological extremes and the vulnerability of sanitation systems. Despite existing legal instruments, cooperation on monitoring and wastewater management remains limited. The integration of basin and coastal planning, improved governance, and transboundary collaboration are essential to reduce pollution and promote ecological and social resilience in the region.
