2025Yvon Mwengwe Muhongo, Eric Nice Nshembe Chishungu · Journal of Advanced Psychology · Democratic Republic of Congo
This study investigated the psychological and environmental impacts of climate change and mining degradation in villages surrounding the Mutanda Mining site in Lualaba province, Democratic Republic of Congo, using a mixed-methods approach. Findings reveal that proximity to the mining site is a major determinant of ecological deterioration and psychological distress. Villages within 5 km of the site showed higher environmental degradation, stronger perceptions of climate change, and significantly elevated eco-anxiety and ecological stress levels. Community resilience mechanisms such as social support, community gardens, and local ecological restoration initiatives partially mitigate psychological impacts.
Environmental trade-offsCommunityHealthClimate changeQuiet right to the city: contributing to urban sustainability by converging allotment and community gardens
2025Michaela Pixová, Christina Plank · Environmental Sociology · Czechia (Prague, Brno)
This paper compared the roles of allotment and community gardens in urban sustainability, using Prague and Brno, Czechia, as case studies. It analyzed perceptions of both by municipal actors, gardeners, and activists across four dimensions: public access to urban greenery, community building, food cultivation, and environment/climate protection. The paper argues that governments' preference for gardens aligned with the status quo undermines citizens' right to the city, urban sustainability, and resilience against future threats.

2025Amon Abraham, Andrew G. Mtewa, Chimwemwe Chiutula, Richard Lizwe Steven Mvula, Alfred Maluwa, Fasil Ejigu Eregno, John Njalam’mano · International Journal of Environmental Research and Public Health · Malawi (Blantyre)
This cross-sectional study in Blantyre, Malawi, characterized antibiotic-resistant bacteria (ARB) prevalence in 35 samples from five livestock farms, including manure, soil, and vegetables. It found high contamination, with Escherichia coli dominating pig manure (52%) and farm soil (35%), and Klebsiella pneumoniae contaminating all sample types (up to 67% in home soils, 60% in vegetables). All manure isolates showed sulfamethoxazole–trimethoprim resistance, and vegetables exhibited severe multidrug resistance, including 100% E. coli resistance to gentamicin. Composting for ≤6 weeks did not eliminate ARBs, indicating manure-amended farms are AMR reservoirs.
