Drivers and vertical CO2 flux balances in a Sahelian agroforestry system: Insights from high frequency measurements S. M. Ba https://doi.org/10.5281/zenodo.19656357
Short summary
This study offers a major advancement in understanding CO2 fluxes in Sahelian agro-silvo-pastoral systems by combining continuous high-frequency automated soil chambers and Eddy Covariance methods over one year. It reveals the critical role of Faidherbia albida trees in carbon cycling and ecosystem productivity, providing rare, high-resolution data to inform climate mitigation strategies and ecosystem models in semi-arid African landscapes.
