Faidherbia-Flux

“Faidherbia-Flux” is a collaborative (> 20 international institutes; > 70 researchers and students) observatory located on a typical agro-silvo-pastoral parkland (groundnut basin, Senegal) dominated by the emblematic and multi-purpose tree species Faidherbia albida, in typical bush-fields cultivated with an annual rotation of pearl millet and groundnut and including the livestock.
It was settled in 2018 by CIRAD and IRD (within a larger Population-Health-Environment observatory; 50 yrs of research and data) using a very large number of instruments and was run continuously since then.
Its main objective is the long term (>10 years) monitoring of microclimate, tree growth, crop yield and exports, net and gross primary productivities, net ecosystem C balance, ecosystem respiration, soil GHG (CO2, H2O, N2O, CH4) balance, hydrological balance (infiltration, evapo-transpiration, sapflow, hydraulic redistributions, groundwater dynamics…), nutrient balance (N, P, K), the role of livestock, the effects of management options, the ecosystem services…
Its second objective is to provide databases of remotely-sensed products, productivity and fluxes to calibrate and validate biophysical models at plant, plot and landscape scales.
This observatory has been hosting international projects (e.g. EU, ANR, CGIAR…). It contributes actively to international networks and databases (e.g. FLUXNET, AMMA-CATCH). Since 2018, 22 peer-reviewed scientific articles were published (in Nov 2023), covering the fields of remote and proxy-sensing, hydrology, microclimate, modelling…
