The global food system, essential for delivering nutritional security to a growing population, is highly vulnerable diverse hazards. This study investigates the feasibility of leveraging an existing systematic database, specifically Conservation Evidence mitigating environmental hazards impacting system. By focusing on human–wildlife conflict as case study, we explored database’s potential inform hazard mitigation strategies. Our analysis revealed significant geographical and taxonomic gaps, varied intervention strategies differences in designs across regions. We identified key challenges, such need comprehensive tagging filtering features, integration non-academic data broader stakeholder engagement. findings underscore complexity adapting conservation databases system applications but highlight benefits free-to-access, systematic, evidence-based approach production mitigation. Future work should focus developing dedicated automation machine learning enhance extraction application efficacy, ultimately improving sustainability.

ABSTRACT Species conservation mainly depends on the of their habitats where an understanding role that have in supporting species diversity and richness is important. This study aimed to determine how heterogeneous growing agriculture corridors support biodiversity birds terms abundance. We assessed diversity, abundance bird six different habitats: miombo woodland, montane forests, lowland agro‐ecosystems, wetland riverine Tanzania's corridor. assumed significantly influence abundance, diversity. recorded 299 which were categorised into 10 trophic guilds. Among guilds, invertebrate‐eating (52%) was species‐rich guild nectarivore (1%), herbivore aquatic (0.67%), terrestrial (0.67%) scavenger (0.34%) least guilds richness, The differed diversity; woodlands had highest levels There even distribution birds, despite fact wetlands agro‐ecosystems few reported there. A number endangered with minimum disturbance. These include Gyps africanus (CR), Ardeola idea , Polemaetus bellicosus Terathopius ecaudatus (EN). In order implement effective measures for habitats, we advocate proper land use, conservation‐friendly implementation connectivity small large scales.
