The natural conservation of coastal lagoons is important not only for their ecological importance, but also because the valuable ecosystem services they provide human welfare and wellbeing. Coastal are shallow semi-enclosed systems that support habitats such as wetlands, mangroves, salt-marshes seagrass meadows, well a rich biodiversity. complex social-ecological with livelihoods, wellbeing to humans. This study assessed, quantified valued 32 lagoons. main findings are: (i) definitions still...
:Coastal wetlands, such as saltmarshes and mangroves, that fringe transitional waters deliver important ecosystem services support human development. Coastal wetlands are complex social-ecological systems occur at all latitudes, from polar regions to the tropics. This overview covers in five continents. The of varying size, catchment population Economic sectors activities around coastal their catchments exert multiple pressures affect state delivery valuable services. All were found be...
Analyzing agricultural and hydrological drought at different timescales is essential for designing adaptation strategies. This study aimed to assess in the Abbay Basin of Ethiopia by using multiple indices, namely standardized precipitation index (SPI), evapotranspiration (SPEI), normalized difference vegetation (NDVI), condition (VCI), severity (DSI). Climate extremes were assessed over between 1981 2022. The results indicate that years 1982 2014 most drought-prone, while year 1988 was...
The goal of this paper is to give a detailed description the coupled physical-biogeochemical model Gulf St. Lawrence that includes dissolved oxygen and carbonate system components, as well analysis riverine contribution for different nitrogen components. A particular attention was paid representation microbial loop in order maintain appropriate level biogeochemical components within over long term simulations. skill demonstrated using situ data, satellite data estimated fluxes from studies...
Land use change is a crucial driving factor in hydrological processes. Understanding its long-term dynamics essential for sustainable water resources management. This study sought to quantify and analyze land between 1985 2021 impacts on the hydrology of Sejnane watershed, northern Tunisia. Remote sensing SWAT model using SUFI-2 algorithm identify most sensitive parameters were used achieve this objective. maps developed 1985, 2001 2021. For last 37 years, watershed experienced slight...
Cette étude a pour but la caractérisation hydrobiologique d’une lagune méditerranéenne (lagune de Bizerte, nord Tunisie) sur base dix campagnes mesures réalisées à une fréquence mensuelle durant l’année 2004, janvier décembre. Deux parmi ces ont fait l’objet d’un maillage fin avec 118 stations en mai et 40 septembre. Le reste n’a couvert que 10 seulement. Pendant campagnes, des paramètres physicochimiques été mesurés (Température, Salinité, Oxygène dissous). Des chimiques biologiques...
A LOICZ Budget Model is applied to the Ichkeul Lake, a wetland ecosystem of South Mediterranean-North African region, evaluate its functioning in order boost water management. The Lake and nutrient budget, net metabolism (NEM), availability, their seasonal changes are estimated using field data. considerable anthropogenic-driven amount nitrogen transferred into N2/N2O atmosphere during dry season with predominance denitrification-anammox processes. primary production impacted by forcing...
Advanced modeling techniques, including Random Forest (RF) and Cubist model (CB), were used to assess the relationship between environmental factors European eels (Anguilla anguilla) abundance provide insights into lake's ecological status while considering climate change anthropogenic influences. A comprehensive dataset, attained through extensive biological monitoring for period 2010-2020, was employed. The performance of models is carried out using key metrics root mean square error...
Dans le cadre du projet de recherche MODEM intitulé "Modélisation Opérationnelle pour Développement des Écosystèmes Marins", un travail a été effectué dans la lagune Bizerte portant sur l'hydrodynamique sédimentaire. Les analyses granulométriques sédiments surface, prélevés à différentes profondeurs, ont permis d'identifier nature ces et préciser les facteurs phénomènes qui interviennent leur transport dépôt. Elles montré que provenant l'érosion côtes sont soumis une dynamique est contrôlée...
