ElderlyHealthToxic heavy metals distribution in urban soils of Africa: a systematic review
2026Nontokozo Pertunia Mkhonza, Sandisiwe Zondo, Samukelisiwe Vilakazi · Environmental Monitoring and Assessment · Africa
A systematic review synthesising 38 peer-reviewed studies (2010–2024) on heavy metals in African urban soils. Weighted mean concentrations of lead, cadmium and chromium exceeded FAO permissible limits in many countries, and industrial activity plus traffic emissions accounted for over half of the identified contamination sources. The review also documents strong geographic bias — Nigeria and Ghana are well studied while Egypt and Ethiopia are barely covered — and a shortage of measurements of bioavailable metal fractions, so the actual dietary risk from crops grown in these cities cannot be determined from this evidence base.
HealthPolicyA systematic review of green gentrification and mental health
2026Catherine D. Brown, Alessandro Rigolon, Piper Zdrodowski, Amber L. Pearson · Health & Place · Global
A systematic review of 16 articles linking green gentrification — rising costs and resident turnover following green space investment — to mental health. Four negative pathways recur: financial stress and housing insecurity from rising housing costs, loss of sense of community as the population changes, exclusion of long-standing residents from the new green space itself, and anxiety about exposure to historical contamination. The review also records benefits, including opportunities for relaxation and improved aesthetics. Because the included studies are largely cross-sectional, the authors state that longitudinal designs are needed before causal claims can be made.
HealthCommunityPolicyPromoting health and inclusion of people with refugee backgrounds through horticulture: A mixed-methods systematic review
2026Louise Emma O'Connor, Sarah Jay · Social Science & Medicine · Global
A mixed-methods systematic review searching four databases for research published between 2015 and 2024 on horticulture and the health and inclusion of people with refugee backgrounds; 20 peer-reviewed studies were included and integrated using a 'best-fit' framework synthesis. Horticultural activity is reported to support mental, physical, psychological, emotional, spiritual, cognitive and economic wellbeing, and to enhance social inclusion through social connections, social capital, collective identity and intercultural exchange. With only 20 studies, mostly qualitative, the review does not quantify effect sizes or identify the conditions under which these benefits do or do not occur.
WelfareCommunityHealthA decision-analysis framework for school garden investments in Vietnam: evaluating trade-offs for nutrition, biodiversity, and economic outcomes
2026Cory Whitney, Thi Thu Giang Luu, Johannes Kopton, Eike Luedeling · Humanities and Social Sciences Communications · Vietnam
This study developed a decision analysis framework to optimize school garden interventions in Vietnamese public and private schools, evaluating their effects on child health, biodiversity, and economic outcomes across five investment scenarios. Results show that passive gardens consistently offer greater biodiversity and health benefits, whereas STEM gardens encounter financial and operational barriers, especially in public schools. The findings highlight significant financial constraints in public schools compared to private ones, revealing critical trade-offs among economic, biodiversity, and health outcomes.

2026Charlie M. Shackleton, Nanamhla Gwedla, Jessica P. R. Thorn · Frontiers in Sustainable Cities · Global
This article discusses the long-standing debate on whether cities can be both dense and green, noting that some cities have achieved both. It questions whether densification is the sole driver of declines in urban green space and proposes deepening the debate by considering eight other dimensions of urban greening. The article also mentions compact urban greening forms like vertical gardens and green roofs, but states that most are poor surrogates for large, connected, biodiverse green spaces.

2026Anqi Liu, Mohd Yazid Mohd Yunos, Shureen Faris Abdul Shukor, Mohd Sallehudin Mat Noor · International Journal of Asian Social Science · Global
This systematic literature review analyzed 33 studies published between 2005 and 2025 in English and Chinese, synthesizing findings on psychological stress sources for special education teachers, the functions and restorative value of school gardens, and research progress on landscapes in special education schools. Primary stress sources for special education teachers included emotional labor, behavioral management, parental communication, and role ambiguity. School gardens were found to have educational, restorative, and therapeutic functions that foster experiential learning, reduce stress, and strengthen teacher-student relationships. However, validated frameworks for restorative design in special education campuses are still lacking.
