Episode notes
Conservation Fieldwork Is Grueling
- Andres Rojas hikes deep into the Colombian rainforest every couple of weeks to replace batteries and memory cards on camera traps and acoustic devices.
- Juan M. Lavista Ferres uses Andres's experience to show how current conservation data collection is slow and physically demanding.
Models Fail Without Faster Data
- Lavista Ferres realized AI models alone weren't enough because data collection and retrieval remained the bottleneck for conservation impact.
- He concluded biodiversity data systems needed a full redesign to deliver real-world change.
Build Simple, Open Systems
- Keep technological solutions simple to maximize adoption and real-world impact in conservation contexts.
- Design for easy assembly, deployment, and open-source access so practitioners can use and improve the system.
