English Abstract: The article critically examines the conservation politics in a transboundary protected area (TBPA) in South Asia, the Sundarbans mangrove forests in Bangladesh and India. It explores the reasons why, despite collaborative measures by the two states, conservation has largely tended to conform to sovereignty practices, making it top-down and exclusionary. This makes the very demarcation of territory for protected areas an intensely political act with significant implications for social equity. The article examines the cultural politics of conservation since contestations to state power have often entailed the articulation of popular sovereignty in the Sundarbans. It argues that the social sustainability of conservation will critically hinge on how issues of resource access and governance are framed, negotiated, and addressed.Spanish Abstract: El artículo examina críticamente la política de conservación en el Área Protegida Transfronteriza (APT): los Sundarbans en Bangladesh e India. Explora por qué, a pesar de la colaboración bilateral, la conservación ha tendido en gran medida a ajustarse a prácticas de soberanía vertical y excluyente. La sola demarcación territorial de las APT, se convierte en un fuerte acto político con implicaciones signifi cativas en la equidad social. El artículo examina la política cultural de la conservación, ya que las protestas al poder del Estado a menudo tienen implicaciones en la articulación de la soberanía popular en los Sundarbans. Argumenta que la sostenibilidad social de la conservación dependerá fundamentalmente de cómo se enmarquen, negocien y aborden las cuestiones de acceso a los recursos y su gobernanza.French Abstract: L’article analyse de manière critique la politique de conservation dans une aire protégée transfrontalière (APT) en Asie du sud, la forêt des mangroves des Sundarbans au Bangladesh et en Inde. Il explore les raisons pour lesquelles, malgré les instruments de coopération entre les deux États, la conservation a adopté des pratiques de souveraineté étatique qui l’ont rendue erticale et exclusive. La démarcation du territoire des aires protégées est un acte profondément politique qui a des implications en matière d´égalité sociale. L’article examine la politique de conservation à travers des actes contestaires vis-à-vis du pouvoir étatique qui ont souvent favorisé une articulation de la souveraineté populaire dans les Sundarbans. Il met en évidence que la durabilité sociale de la conservation dépend de l’encadrement, de la négociation et de la promotion des thèmes d’accès aux ressources et de la gouvernance.

Samples were collected from Arpangasia and Kholpetua rivers within the Sundarbans in Bangladesh during February to March and December 2018. Among several forms was found a tightly prostrate brown alga occurring on moist parts of mangrove plants and clayey soil. Flattened brownish thalli tightly attached to pneumatophores and lower parts of mangrove trunks, spreading and branching dichotomously, sometimes overlapping and attached by means of unbranched marginal and sub-marginal rhizoids were collected. Distinct marginal sori are well developed in fertile specimens. On the basis of these characters, the sample has been identified as Dictyota adnata Zanardini which is herein reported as a new record for Bangladesh.

Abstract BackgroundAttempt to compare the phonological pattern of the three mangrove species: Heritiera fomes, Bruguiera sexangula, and Xylocapus mekongensis in the Sundarbans mangrove forest by observing the litterfall data over 3 years.ResultsAll these three species showed highest litterfall of leaves and stipules in summer and lowest in winter. In case of B. sexangula, it also showed its second peak of leaves litterfall in the rainy season. Branch litterfall for the three species was occurred all over the year without having a distinct seasonal pattern. Flowering was observed in February – June and March - May for H. fomes and X. mekomgensis, respectively. Fruiting was observed for H. fomes and X. mekongensis in between the month of March – May and April – June respectively. Peak of mature fruit or seed litterfall was observed in July and August for both H. fomes and X. mekongensis respectively. Litterfall of flower buds, flowers and propagule for B. sexangula was observed throughout the year and peak flower buds, flowers, and propagule litterfall was found in the month of January, March, and July respectively. Kendall’s coefficient of concordance showed that all the organs of litterfall were concordant during the study period. Autocorrelation coefficient revealed that all the parts of litterfall followed a clear annual cycle except branches. Mean total litterfall was calculated 1014.6±12.7 g m-2 year-1 for H. fomes, 1047.3±21.3 g m-2 year-1 for X. mekongensis and 1640.2±14.1 g m-2 year-1 for B. sexangula of which leaves litterfall contributed more than 50% of total litterfall for all the three species. H. fomes, B. sexangula and X. mekongensis none of them exhibit any correlation between stipules litterfall and reproductive organs litterfall.ConclusionThe findings may contribute to an understanding of vegetative and reproductive phenology, litterfall production, and carbon sequestration rate of the major mangrove species in Sundarbans mangrove forests, and also its role in global C budgets.

The conservation of coastal wetland ecosystems, like mangrove forests and salt marshes, represents a critical strategy for mitigating atmospheric emissions and climate change in the 21st century. Yet the existence of these environments is threatened by human-induced disturbances, namely deforestation and accelerated sea-level rise. Coastal systems maintain surface elevation in response to sea-level rise through a combination of physical and biological processes both above and below the ground surface. The quantification and relative contribution of belowground process controls (e.g., seasonal water content, organic matter decomposition) on surface elevation change is largely unexplored but crucial for informing coastal ecosystem sustainability. To address this knowledge deficit, we integrated measurements of surface elevation change of the live root zone (0.5 to 1 m depth) with geotechnical data from co-located sediment cores in the Sundarbans mangrove forest (SMF) of southwest Bangladesh. Core data reveal that the primary belowground controls on surface elevation change include seasonal fluctuations in pore-water content and the relative abundance of fine-grained sediments capable of volumetric expansion and contraction, supporting an elevation gain of ~2.42 ± 0.26 cm yr−1. In contrast to many mangrove environments, the soils of the SMF contain little organic matter and are dominantly composed (>90%) of inorganic clastic sediments. The mineral-rich soil texture likely leads to less compaction-induced subsidence as compared to organic-rich substrates and facilitates surface equilibrium in response to sea level rise. Despite a relatively high soil bulk density, soil carbon (C) density of the SMF is very low owing to the dearth of preserved organic content. However, rates of C accumulation are balanced out by locally high accretion rates, rendering the SMF a greater sink of terrestrial C than the worldwide mangrove average. The findings of this study demonstrate that C accumulation in the SMF, and possibly other alluvial mangrove forests, is highly dependent on the continued delivery of sediment to the mangrove platform and associated settings.
