“…A nivel del Caribe colombiano esto cobra mayor importancia, teniendo en cuenta los datos registrados en Serrano et al (2021), los cuáles muestran una aproximación al cálculo del carbono en los sedimentos de los pastos marinos del país, destacando que el valor de los stocks en los sedimentos de La Guajira y San Andrés superan los promedios globales, alcanzando los 240 Mg C/ha. Esto, sumado a lo registrado por Guerra et al (2020) para San Andrés, donde se calculó que el valor de carbono en los sedimentos osciló entre 91 y 144 Mg C/ha, y lo hallado por Congdon et al (2017) y Gullström et al (2018), donde se evidenció que el contenido de carbono en sedimentos es más alto en zonas donde la cobertura y la biomasa tiende a ser mayor, refrenda el hecho de que la protección del sistema de biomasa aérea y subterránea repercute directamente en los reservorios de los sedimentos, y por ende en la optimización de los procesos de captura de carbono.…”

“…At level of the Colombian Caribbean, this becomes more important, taking into account the data recorded in Serrano et al (2021), which shows an approximation of the carbon values in the sediments of the country's seagrasses, highlighting that the stocks in the sediments of La Guajira and San Andrés exceed global averages, reaching 240 Mg C/ ha. This, added to the study from Guerra et al (2020) for San Andrés, where the value of carbon in the sediments ranged between 91 and 144 Mg C/ha, and the information reported by Congdon et al (2017) and Gullström et al (2018), where it was shown that the carbon content in sediments is higher in areas where coverage and biomass tend to be greater, endorses the fact that the protection of the aerial and underground biomass system has a direct impact on the reservoirs of sediments, and therefore in the optimization of carbon capture processes.…”

Seagrass meadows have stood out for being very effective fixing atmospheric carbon, among others, due to their ability to produce plant biomass. Therefore, the values of shoot density (m2), biomass (cores) and carbon present in 12 locations with Thalassia testudinum at the Colombian Caribbean (La Guajira and San Andrés Island) were quantified. The biological samples were processed in laboratory until obtaining the values of aerial, underground and total dry weight, and the estimation of the carbon was stablishing from a ratio of 35 % of the dry biomass. Statistical tests were carried out to determine significant differences between the sites, highlighting the aerial biomass in La Guajira and the underground biomass in San Andrés. It was calculated that the total carbon in the seagrasses’ biomass from La Guajira were 197 484 Mg C and in San Andrés 1835.4 Mg C. The difference between locations were due to particular geomorphological and intrinsic factors. It is highlighted that, although the carbon retained in the biomass (aerial and underground) is comparatively lower than in sediments, it constitutes the pillar of conservation of both carbon sink as well as for the sustainability of the ecosystem.

Blue carbon has been proposed as a nature-based solution for climate change mitigation; however, a limited number of published works and data and knowledge gaps hinder the development of small island developing states’ (SIDS) national blue carbon resources globally. This paper reviews the blue carbon ecosystems of Seychelles as a case study in the context of SIDS, comparing estimations by the Blue Carbon Lab and recent blue carbon (mangrove and seagrass) evaluations submitted to the Seychelles national government. Mangroves (2195 ha, 80% in Aldabra Atoll) and seagrasses (142,065 ha) dominate in Seychelles, with coral reefs having the potential for carbon sequestration (169,000 ha). Seychelles is on track to protecting its blue carbon, but these systems are threatened by rising sea levels, coastal squeeze, erosion, severe storms, and human activities. The importance of carbon inventories, accounting institutions, and continuous monitoring of blue carbon systems is discussed. Blue accounting is necessary for accurate accounting of carbon sequestration and carbon storage, generating carbon credits, and representing impactful reductions in greenhouse gases for NDCs. Challenges and opportunities include policy legislation regarding ownership rights, accreditation and certification for carbon credits, sustainable financing mechanisms like natural asset companies and blue tokens, local engagement for long-term success, and carbon market dynamics following COP27. The restoration and regulation of blue carbon resources for optimal ecosystem services delivery, carbon inventories, and blue carbon policy are recommended development priorities. Blue carbon ecosystems have the potential to contribute to NDCs of SIDS while simultaneously offering sustainable development pathways for local communities through the multiple ecosystem services they provide.

“…In terms of hydrodynamics this could mean no alteration in trait response and therefore no consequent impact on blue carbon stocks. Recent research has highlighted seagrass beds connected to other coastal ecosystems have higher blue carbon (Guerra‐Vargas et al, 2020).…”

1. Wetland plants form blue carbon ecosystems, which are key for climate change mitigation yet threatened by multiple local and global stresses. The capacity of blue carbon ecosystems to store large amounts of carbon relies on ecological processes, many of them regulated by plant traits that are shaped by the stress that plants encounter.2. This manuscript provides a perspective to investigate the effects of stress on carbon storage and sequestration capacity of blue carbon ecosystems based on the plant traits.3. A first step was to identify the biochemical, physiological, morphological and growth and development traits involved in the processes controlling carbon storage and sequestration in blue carbon ecosystems.4. Second, the existing knowledge on the stress effects on blue carbon processes and ecosystems was evaluated. 5. Finally, the application of the trait-based approach to understand and predict carbon dynamics in blue carbon ecosystems under different stresses' feedback was discussed.6. The conclusions provide key recommendations for a trait-based approach in which the trinomial local and global stresses, plant traits and blue carbon are embraced together to identify the feedbacks between them, along with specific attention to the plant traits across the seascape, the stress interactions and the need of plant trait standardization.
