Nature-based solutions (NbS) are multidimensional, resource-efficient, and sustainable growth approaches to cope with current challenges, including biodiversity carbon loss, pollution, climate change land degradation. Amongst NbS, urban forestry is an important tool enhance environmental resilience sustainability, providing useful ecosystem services for human well-being. In this context, using suitable soil plant indicators allows us evaluate the efficiency of in sustaining functionality. Effective should be sensitive changes representative ecological processes. Many studies focus on selection or indicators. The prior investigations considered soil–plant interaction related complex heterarchical bidirectional effects involving strategy biota. choice use system could innovative better assess following: (1) ability support healthy plants their improve air quality; (2) effect processes, particular nutrient cycles. This review investigates suitability cycles, e.g., stoichiometry, enzyme activity nitrogen stable isotopes, as valuable tools planning evaluating effectiveness interventions.

Inefficient urban transformations pose multifaceted challenges. In this context, agriculture (UA) can address environmental and socio-economic issues. Despite recent UA policies in São Paulo, the lack of data hampers comprehensive evaluations, highlighting need for robust indicators to enhance sustainability. This article assesses Paulo’s potential using an Ecosystem Services (ES)-based approach, combining ES spatial mapping a producer survey at 49 sites. Results show natural habitats anthropic areas within urbanised land, especially south, with high habitat quality scores. Nine were identified: food supply, commercialisation, income generation, waste mediation, lifecycle maintenance, soil formation, leisure/social, well-being, education. Utilising mixed methods, study provides innovative insights into related offering valuable input planning.
