[Mental health and wellbeing: The contribution of trees and forests to diverse populations in Britain]. / Santé mentale et bien-être : l'apport des arbres et des forêts au bénéfice de différentes populations en Grande-Bretagne.

This paper explores the potential contribution of trees and forest to the mental wellbeing of diverse populations in Britain. We use a conceptual framework that makes a distinction between three different levels of engagement: everyday life; green health promotion; and green therapeutic care. We then use researched and evaluated case studies in Britain to provide examples associated with these three levels of engagement. The case studies illustrate that practical approaches and interventions are developing rapidly in the Britain. Finally we discuss the main pathways and mechanisms that link mental health and wellbeing and trees and forests. We outline that there are limitations to the current international evidence base and call for consistent approaches within and between countries using a range of methodologies to capture the nuances of the complex relationships between trees, forests and mental health and wellbeing.

Co-creating urban green infrastructure connecting people and nature: A guiding framework and approach.

Urban green infrastructure (UGI) and nature-based solutions are increasingly recognized as instruments to address urban sustainability challenges, yet rely on a good understanding of complex social-ecological system (SES) to function adequately. Adaptive co-management (ACM), engaging a broad variety of stakeholders in collaborative learning, is an effective strategy to improve the resilience of a SES. However, ACM studies have been criticized for neglecting the urban context, while also offering little clarity on process objectives and outcomes. To address these knowledge gaps, while also drawing attention to the important issue of socially inclusive UGI development, we present a guiding framework and approach to encourage the ACM of UGI featuring two main components. Firstly, a Learning Alliance (LA) serves as an instrument for collaborative learning and experimentation across different scales. To facilitate upscaling, we propose to establish a complementary Urban Learning Lab (ULL) to facilitate a regular exchange between the LA and legitimate peripheral networks and stakeholders in the city region. Secondly, a stepwise approach to SES analysis serves to engage a representative group of stakeholders in the LAs and ULLs, and support the processes of setting LA objectives and monitoring of adaptive capacity. We illustrate our approach to the ACM of UGI with a case study of LivadaLAB in Ljubljana, Slovenia. Applying the framework and approach, we demonstrate increased adaptive capacity of the SES around UGI as indicated by: 1) improved overall stakeholder salience, in particular for previously disempowered actor groups, 2) increased number and strength of connections between stakeholders, and 3) the consideration of a broader range of sustainable development objectives by stakeholders in their daily practice.
