“…Increasing soil volume results in raised surface elevation of the wetland, so that on decadal scales its elevation roughly tracks sea level rise (e.g. Chmura et al 2001;Ellison 2008). This increase in elevation is accompanied by lateral expansion of the marsh or mangrove swamp over tidal flats in the lower intertidal zone and inland over adjacent terrestrial ecosystems.…”

Part 1 of this review synthesizes recent research on status and climate vulnerability of freshwater and saltwater wetlands, and their contribution to addressing climate change (carbon cycle, adaptation, resilience). Peatlands and vegetated coastal wetlands are among the most carbon rich sinks on the planet sequestering approximately as much carbon as do global forest ecosystems. Estimates of the consequences of rising temperature on current wetland carbon storage and future carbon sequestration potential are summarized. We also demonstrate the need to prevent drying of wetlands and thawing of permafrost by disturbances and rising temperatures to protect wetland carbon stores and climate adaptation/resiliency ecosystem services. Preventing further wetland loss is found to be important in limiting future emissions to meet climate goals, but is seldom considered. In Part 2, the paper explores the policy and management realm from international to national, subnational and local levels to identify strategies and policies reflecting an integrated understanding of both wetland and climate change science. Specific recommendations are made to capture synergies between wetlands and carbon cycle management, adaptation and resiliency to further enable researchers, policy makers and practitioners to protect wetland carbon and climate adaptation/resiliency ecosystem services.

“…Most of these are muddy rather than sandy or rocky. Climatic factors that affect the distribution of mangroves include changes in sea level, precipitation, and temperature [16,19]. Given that mangroves generally grow between mean sea-level and mean high water, their sedimentary records have been used as both directional and precise sea-level indicators [19][20][21][22].…”

A palynological and palaeoclimatological record from the southern Philippines since the Last Glacial Maximum

A palynological analysis of a marine sediment core in the southern Philippines, provides a detailed regional vegetation and climate history for the West Pacific Warm Pool (WPWP) since the Last Glacial Maximum (LGM). Chronology was determined by a detailed oxygen isotope record. A higher representation of pollen from tropical upper montane rainforest during the LGM indicate that this forest type moved down along elevation, probabaly due to the lowered temperature. During the last deglaciation and the early Holocene, mangroves were more expanded and tropical mid and upper montane rainforests were restricted, suggesting a rising sea-level and temperature increase. Herbaceous pollen and pteridophyte spore records indicate a much drier condition during the LGM than the Holocene. Mangrove development is controlled by conditions at the river mouth influenced by river discharge. Pteridophyte spores are abundant in wet conditions and are mainly transported by rivers. During the mid-Holocene, the reduction in mangrove pollen and pteridophyte spore appears to be a result of climate change: mainly decrease in river discharge. This may have been affected by the decreasing intensity of the Southeast Asian Monsoon, and the increasing frequency and intensity of warm ENSO events, El Niño, in this region.Last Glacial Maximum, tropical rainforests, palynological analyses, sea-level change, river discharge Citation:Bian Y P, Jian Z M, Weng C Y, et al.

“…Dentro de estas zonas costeras tropicales y subtropicales de todo el mundo, los manglares son uno de los ecosistemas más vulnerables en las condiciones actuales y escenarios futuros de cambios globales tales como el ascenso del nivel medio del mar y la progresiva deforestación (Duke et al 2007, Kirwan y Megonigal 2013, Lugo et al 2014. Ante estos dos cambios globales, se plantea la hipótesis que los manglares del Caribe (incluyendo el Caribe colombiano) son muy vulnerables debido a: 1) la magnitud de las amenazas (Ellison 2008, Ellison y Farnsworth 1996, 2) las reducidas áreas (Gilman et al 2008) y 3) la baja riqueza de especies de mangles (Polidoro et al 2010).…”

ResumenLas alteraciones del nivel medio local del mar y la deforestación son dos cambios globales que impactan severamente a los manglares del Caribe colombiano, pero poco se ha discutido acerca de ellos en el golfo de Urabá. El objetivo de esta revisión es sintetizar la literatura publicada sobre esos temas en esta área. Este golfo presenta extensas áreas estructuralmente diferentes a las del resto del Caribe, que están disminuyendo y degradándose como producto de: a) la erosión costera y el aumento del nivel del mar; b) la entresaca de árboles y la expansión de la frontera agrícola; y c) la deforestación de las cuencas y la exportación de sedimentos hacia los estuarios. El delta del río Atrato y varios microdeltas de la costa oriental se expandieron, mientras que la ensenada de Rionegro permaneció estable, al menos durante el siglo XX. La costa oriental, con las áreas más pequeñas de manglar, se erosionó varios metros por año debido a la deriva litoral. Cerca a la cabecera municipal de Turbo, la entresaca de árboles para diferentes fines ha reducido el diámetro promedio de Rhizophora mangle y ha aumentado el valor de importancia de Laguncularia racemosa, afectando el reservorio de biomasa y carbono aéreos. La expansión de la frontera agropecuaria ha reducido la extensión de los rodales interiores de Avicennia germinans. La alta tasa de deforestación de las cuencas y planicies costeras de la zona bananera ha incrementado la carga de sedimentos de los ríos, la cual se acumula en los deltas. En estos, los manglares retienen cantidades significativas de sedimentos, con posible detrimento de la colonización y sobrevivencia de plántulas y macroinvertebrados bénticos. En conclusión, en el golfo de Urabá se presentan en la actualidad cambios globales naturales y antropogénicos de magnitudes significativas, tanto en la zona litoral como en las cuencas costeras, los cuales requieren una urgente implementación de medidas de adaptación dentro de los planes de manejo de los manglares y de la zona costera.Palabras clave: conversión agrícola, deforestación, erosión costera, manglares, sedimentación A AbstractAccelerated mean sea level rise and deforestation are two global changes severely impacting mangroves along the Colombian Caribbean coast, but little has been discussed about them for the Gulf of Urabá. The objective of this review is to synthesize the published literature on such topics available to date for this area. This gulf holds extensive areas, structurally different from the rest of the Caribbean, which are shrinking and degrading as a consequence of: a) coastal erosion and sea level rise; b) selective logging and agricultural expansion; and c) watershed deforestation and sediment exports to the estuaries. The Atrato River delta, and several microdeltas located along the eastern coast have expanded, while the Rionegro Cove has remained relatively unchanged, at least during the 20 th century. The eastern coast, with the smalles mangrove patches, have eroded at a rate of various meters per year due to the littoral...
