Introduction to non-invasive biometric sensors

Non-invasive sensors, which are installed around the barn, include surveillance cameras and sensors in the feeding systems to monitor animal weight and feed intake. Non-invasive sensors also include sensors that can be easily attached to animals, such as pedometers, GPS and MEMS (microelectromechanical) based activity sensors, that can be used to monitor livestock behaviour.

Our Food: where do emissions come from?

CO2 is not the only the critical source of GHG emission. For most foods, most GHG emissions result from land use change and from processes at the farm stage which include processes such as the application of fertilizers and enteric fermentation, accounting for more than 80% of the footprint for most foods.
