Remote Sensing Assessment of Land-Cover and Surface-Water Changes Associated with Black-Sand Mining Areas in an Arid Environment: A Multi-Index Exploratory Case Study from N’Diago, Mauritania (2014–2026)
Black-sand mining is an under-studied anthropogenic pressure on arid coastal environments, where sparse vegetation and slow natural recovery limit conventional impact assessment. Despite the recent expansion of heavy-mineral extraction along the Mauritanian coast, no spatio-temporal analysis has quantified its effects...
