Crucial to the creation of a market-based carbon credit trading system is the monitoring and verification of agricultural practices that promote carbon storage. Using remotely sensed images for thi...
Conservation agriculture practices (CAs) have been internationally promoted and used for decades to enhance soil health mitigate loss. An additional benefit of CAs has mitigation agricultural runoff impacts on aquatic ecosystems. Countries across the globe agencies that provide programs farmers implement a variety CAs.
