(2014) published a paper in {G}eoforum mapping and quantifying a massive mangrove loss. {H}owever, remote sensing and mapping shortcomings have been identified. {T}he 2010 map used in the {C}arney et al. (2014) paper is accurate, however, as a result of errors in georeferencing, window extraction and classification, their 1986 map is not. {M}angrove and mudflats are grouped in the same class. {T}he addition of a stacked classification to the image processing used by {C}arney et al. (2014) enables the realization of a correction of the map, and thus the production of results similar to other studies. {T}he supposed loss of mangroves appears to have been the consequence of this classification error. {I}n fact, we observe a progression of 8804 ha instead of the regression of 37,196 ha assessed by the authors. {T}his published discrepancy, which is in opposition to any other study of this area, must be discussed in order to clarify for scholars and policymakers the actual dynamics of mangrove change in the studied region.}, keywords = {{MANGROVE} ; {FORET} ; {ESTUAIRE} ; {EVOLUTION} ; {TELEDETECTION} {SPATIALE} ; {CLASSIFICATION} ; {CARTE} ; {ERREUR} ; {GEOREFERENCEMENT} ; {CONTROVERSE} ; {SENEGAL} ; {CASAMANCE} ; {SALOUM}}, booktitle = {}, journal = {{R}emote {S}ensing {A}pplications. {S}ociety and {E}nvironment}, volume = {13}, numero = {}, pages = {337--347}, ISSN = {2352-9385}, year = {2019}, DOI = {10.1016/j.rsase.2018.12.001}, URL = {https://www.documentation.ird.fr/hor/fdi:010078383}, }
