For over two decades, the Soils Theme of World Agroforestry (ICRAF) in collaboration with partners has been at the cutting edge globally of innovations in soil spectroscopy, creating a large planetary database of soil data, which plays an important role in agricultural research and ecosystem restoration.
In line with the CGIAR’s Open Access Open Data policy, ICRAF is committed to sharing data using credible data repositories such as World Agroforestry Research Data Repository where data and associated meta data are stored and shared in a trackable and citable way, making data accessible to both researchers and the public.
Check out some of the open access spectral datasets here:
