This umbrella review synthesizes evidence on mechanisms linking human and ecological flourishing across nine systematic reviews. Psychological pathways (attention restoration, stress reduction) show the most consistent support, but overall evidence for causality is weak and derived predominantly from cross-sectional and qualitative designs, with no existing evidence on how non-human flourishing reciprocally influences human outcomes.
Umbrella review of systematic reviews. Mechanisms operating at the interface of human and non-human natural entities; systematic reviews examining interconnected flourishing across these domains. Intervention: Ecological-collective-flourishing (e-co-flourishing) mechanisms including attention restoration, stress reduction, social cohesion, physical activity, and environmental quality enhancement.
Psychological mechanisms (attention restoration, reduced stress) showed most consistent support across reviews Social mechanisms (cohesion and contact) identified as cross-domain pathways Physical activity and environmental quality improvements supported as mechanisms

This evidence synthesis indicates that while psychological mechanisms linking nature contact to human well-being are relatively robust, the field lacks rigorous causal evidence and has not yet demonstrated how ecological health reciprocally benefits human flourishing. Practitioners should interpret current evidence as hypothesis-generating rather than practice-directive, pending more rigorous longitudinal and experimental designs.

Ecological-collective-flourishing (e-co-flourishing) describes the interconnected flourishing of human and non-human natural entities. Despite existing conceptual frameworks, translation into practice remains inadequate owing to insufficient synthesis of empirically tested mechanisms driving change across human and ecological systems. We conducted an umbrella review of systematic reviews examining mechanisms at the e-co-flourishing interface. Searches of seven databases and four grey literature sources identified nine eligible reviews. Evidence supported several cross-domain mechanisms, including psychological (eg, attention restoration and reduced stress), social (eg, cohesion and contact), physical (eg, activity), and environmental pathways (eg, reduced stressors and enhanced environmental quality). Psychological mechanisms showed the most consistent support, whereas evidence for other mechanism domains was mixed. Evidence for causality was weak and largely derived from cross-sectional and qualitative studies, and no reviews examined reciprocal mechanisms influencing both human and non-human flourishing. Future research should prioritise rigorous designs, theory-driven testing, and replication to strengthen evidence for equitable and sustainable e-co-flourishing pathways.
