The potential for Blue Carbon ecosystems to combat climate change and provide co-benefits was discussed in the recent influential Intergovernmental Panel on Climate Change Special Report Ocean Cryosphere a Changing Climate. In terms of Carbon, report mainly focused coastal wetlands did not address socio-economic considerations using natural ocean systems reduce risks disruption. this paper, we discuss resources coastal, open-ocean deep-sea highlight benefits measures such as restoration creation well conservation protection helping unleash their mitigating risks. We also challenges—such valuation governance—to marshaling mitigation role need policy action capital market development, global coordination. Efforts identify resolve these challenges could both maintain harness store carbon help fight change.

A review of seagrass ecosystem services: providing nature-based solutions for a changing world

Hydrobiologia, Journal Year: 2023, Volume and Issue: 850(12-13), P. 2655 - 2670

Published: June 6, 2023

Abstract Seagrasses are marine flowering plants, which form extensive meadows in intertidal and shallow water environments. They provide a wide range of ecosystem services, directly or indirectly benefit humans can be grouped into four broad categories: provisioning (e.g. food production); regulating carbon sequestration); supporting primary cultural recreational, eco-tourism). This study provides review publications focusing on seagrass services provision to identify knowledge gaps improve our understanding the use these habitats as nature-based solutions societal challenges, such climate change. Results showed that some namely provision, sequestration, maintenance biodiversity/nursery receive higher level focus attention than others, regulation diseases social relations, rarely, if ever, included studies. It is clear order fully comprehend solution potential held by ecosystems, studies need consider whole, also combine share results across global regions, better understand impacts degradation loss ecosystems worldwide. Suggestions include applying novel technologies remote sensing ecological niche modelling address main research, like meadow extent connectivity within landscapes, incorporate preservation management plans.

It's time to broaden what we consider a ‘blue carbon ecosystem’

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(5)

Published: May 1, 2024

Abstract Photoautotrophic marine ecosystems can lock up organic carbon in their biomass and the associated sediments they trap over millennia are thus regarded as blue ecosystems. Because of ability to for millennia, is receiving much attention within United Nations' 2030 Agenda Sustainable Development a nature‐based solution (NBS) climate change, but classically still focuses on seagrass meadows, mangrove forests, tidal marshes. However, other coastal could also be important storage, remain largely neglected both cycling budgets NBS strategic planning. Using meta‐analysis 253 research publications, we identify ecosystems—including mud flats, fjords, coralline algal (rhodolith) beds, some components or coral reef systems—with strong capacity act sinks certain situations. Features that promote burial these ‘non‐classical’ included: (1) balancing release by calcification via uptake at individual ecosystem levels; (2) high rates allochthonous supply because particle trapping capacity; (3) preservation low remineralization rates; (4) location depositional environments. Some features context‐dependent, meaning were locations, not others. Therefore, provide universal framework evaluate likelihood given behave sink context. Overall, this paper seeks encourage consideration non‐classical strategies, allowing more complete accounting.

Assessment of heavy metals at mangrove ecosystem, applying multiple approaches using in-situ and remote sensing techniques, Red Sea, Egypt

Environmental Science and Pollution Research, Journal Year: 2024, Volume and Issue: 31(5), P. 8118 - 8133

Published: Jan. 4, 2024

Abstract Mangrove areas are considered the most retention zone for heavy metal pollution as it work an edge that aggregates land and sea sediments. This study aims to examine if metals’ existence in mangrove sediment is related contamination or natural resources. In addition, gives interpretation of origin these metals along Egyptian Red Sea coast. Twenty-two samples sediments were collected then, analyzed (Mn, Ni, Cu, Fe, Cd, Ag, Pb) using inductively coupled plasma mass spectroscopy (ICP-MS). Integration between in-situ data, indices, remote sensing geographical information science (GIS), multivariate statistical analysis techniques (PCA) assess clarify spatial at a regional scale. The average concentration from shown be substantially lower than referenced value, ranging moderate significant except levels Ag very high. concentrations expected naturally rather anthropogenic confirmed by mapping alteration zones spots.

Abstract Globally, soils and sediments are affected by the bioturbation activities of benthic species. The consequences these particularly impactful in intertidal sediment, which is generally anoxic nutrient‐poor. Mangrove particular interest because, as most productive forests one important stores blue carbon, they provide global‐scale ecosystem services. mangrove sediment microbiome fundamental for functioning, influencing efficiency nutrient cycling abundance distribution key biological elements. Redox reactions bioturbated can be extremely complex, with reaction creating a cascade effect on succession respiration pathways. This facilitates overlap different respiratory metabolisms element cycles including nitrogen, sulphur iron cycles, among others. Considering that all ecological functions services provided environments involve microorganisms, this work reviews microbial roles relation to animals plants, main engineers.
