abstract = "Sea level rise and climate change are major forces driving wetland
dynamics. The northern Brazilian coast has one of the largest
continuous mangrove areas on Earth, with the mangroves from the
Bragan{\c{c}}a Peninsula, in eastern Amazonia, being the most
representative ones. These mangroves have migrated into higher
tidal flats over recent years. We analyzed spatialtemporal changes
of vegetation units adapted to different physicalchemical
conditions along the Bragan{\c{c}}a Peninsula in order to
decipher possible causes responsible for such recent mangrove
dynamics. The investigation was based on time series analysis of a
33-year (19842017) database consisting of satellite and drone
images. These data were combined with digital elevation models
based on topographical data obtained by photogrammetry, theodolite
and hydrotopographic devices. During this time frame, mangroves
invaded 2.7 km2 of inner tidal flats, which is compatible with a
rise in relative sea level (RSL) and with a rainfall decreasing.
Such topography-dependent dynamic suggests that an increased
frequency of tidal inundation decreased porewater salinity and
caused mangroves to expand into topographically higher grounds.
However, the study area contains small basins, that are less
affected by tidal inundation, and Avicennia trees are dying in
these locations due to increased porewater salinity, probably
caused by a decreased rainfall. We propose that climate and RSL
are responsible for driving the death of mangroves in the study
area, and their migration into the topographically highest tidal
flats. Assuming a RSL rise of 5 mm/yr under stable rainfall, or a
RSL rise of 3 mm/yr accompanied by decreased rainfall, it is
projected that mangrove areas will expand by 2.93 or 1.35 km2 ,
respectively, by the end of this century. The combination of
photogrammetry with theodolite/hydrotopographic surveying proved
to be an efficient and innovative process for monitoring and
evaluating the impacts of global changes on mangroves.",
