Aerial images detect and track food security threats for millions of African farmers

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Peer-Reviewed Publication

New research shows how a combination of imagery from mobile phones, drones and satellites can be used to clamp down on banana threats. The images of varying resolutions are fed into a platform 'trained' through machine learning to identify banana crops and analyze threats with 97% overall accuracy.

The next generation of biodiversity conservation targets must aim higher than ever

The Alliance of Bioversity International and the International Center for Tropical Agriculture
Peer-Reviewed Publication

Writing this week in Science, 40 researchers argue for a set of holistic actions for new biodiversity goals that are unambiguously clear, sufficiently ambitious, and based on the best knowledge available. Most importantly, the goals need to aim higher if they are to be successful in the face of worsening trends for the climate and life on Earth.
