Abstract Soil health is a critical component of nature‐based solutions (NbS), underpinning ecosystem multifunctionality and resilience by supporting biodiversity, improving carbon sequestration storage, regulating water flow enhancing plant productivity. For this reason, NbS often aim to protect soil restore degraded soil. Robust monitoring needed adaptively manage projects, identify best practices minimize trade‐offs between goals, but assessment underrepresented in programmes. This paper examines challenges opportunities selecting suitable metrics. We find that standardization can facilitate widespread health, with benefits for stakeholders user groups. However, brings key challenges, including the complexity local variability systems diverse priorities, skills resources stakeholders. To address this, we propose flexible, interdisciplinary approach combining science, ecology socio‐economic insights. introduce an interactive tool help users select biodiversity metrics, which are context scale‐specific, suggest avenues future research. conclude integrating into through new improved approaches, newly available datasets, supportive policies stakeholder collaboration enhance effectiveness NbS, contributing significantly global sustainability goals.

Conversion of forest to agricultural land (agroforestry and monoculture) has a negative impact on soil macrofauna diversity. Soil have key role in maintaining fertility through decomposition supporting the productive capacity ecosystems. This study aimed at determining diversity litter rate agroforestry monoculture investigating correlation between rate. involved field laboratory activities. Litter traps were installed for observation, identification was carried out laboratory, bags used observation. Data analysis conducted determine species similarity plantations. The calculation index (H’) shows that complex simple moderate, while candlenut low macrofauna. these sites is (similarity below 50%). relatively high (0.01 g/day). very strong. Meanwhile, agroforestry, low.
