Landdegradation

Welcome

to the Homepage of the joint project SPACES2 'South Africa Land Degradation Monitor (SALDi)'. The project developed new approaches for the spatially explicit detection of land degradation in South Africa. The project was funded by the BMBF over the period from Nov. 2018 to April 2023. However, data analysis and publication activities continue in 2024.
