Kelps are part of large brown macroalgae species with a fundamental role in temperate to subpolar coastal marine ecosystems and their cultivation has been expanding as several efforts countries' policies. This study explores the relevance post-harvesting logistics planning involving operations emerging seaweed-based supply chains including kelp species. In Irish context, we explore potential collaboration among low-tropic ocean farming sectors regarding shared space infrastructure rural remote landscapes. Based on empirical data novel methodological approach, multi-method analysis was performed geographic information systems, mathematical modelling qualitative content analysis.

Seaweed Aquaculture for Carbon Farming: An Assessment Under the EU's QU.A.L.ITY (Quantification, Additionality, Long‐Term Storage, Sustainability) Framework

ABSTRACT There is growing interest in establishing a seaweed farming industry Europe, and this has the potential for being mechanism atmospheric carbon dioxide removal (CDR). The EU recognises of CDR to help meet climate change targets, but also acknowledges importance creating credible markets ecosystem services (ES) through voluntary promote sustainable investment avoid claims greenwashing. In response this, proposed framework (termed QU.A.L.ITY) establishment certification schemes, based on four criteria quantifiable, additionality, long‐term storage overall sustainability. While aquaculture holds could QU.A.L.ITY generic level, specific projects face hurdles data collection, standardized methodologies, sediment protection regulations, applicability taxonomy. Robust frameworks like EU's are crucial greenwashing ensure action CDR.

Can the Emerging European Seaweed Industry Contribute to Climate Change Mitigation by Enhancing Carbon Sequestration?

Reviews in Aquaculture, Journal Year: 2025, Volume and Issue: 17(2)

Published: March 1, 2025

ABSTRACT Blue carbon habitats, which exhibit high rates of natural sequestration, typically refer to salt marshes, seagrass meadows, and mangrove forests. Recent studies, however, have argued for the inclusion seaweed‐dominated like kelp forests, into blue frameworks. Farmed seaweed may also function as a habitat, with large‐scale aquaculture suggested climate change mitigation strategy, but evidence base remains limited. Here, existing knowledge on mechanisms influencing uptake, release, transport, storage from farms was synthesised, literature review conducted quantify associated sequestration. We identified strong geographical methodological biases in literature, majority studies Asia focusing primary production proxy sequestration potential.

A blueprint for national assessments of the blue carbon capacity of kelp forests applied to Canada’s coastline

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2024, Volume and Issue: unknown

Published: April 6, 2024

Abstract Kelp forests offer substantial carbon fixation, with the potential to contribute natural climate solutions (NCS). However, be included in national NCS inventories, governments must first quantify kelp-derived stocks and fluxes leading sequestration. Here, we present a blueprint for assessing sequestration capacity of kelp which data synthesis Bayesian hierarchical modelling enable estimates forest production, storage, export from limited data. Applying this Canada’s extensive coastline, find store an estimated 1.4 Tg C short-term biomass produce 3.1 yr -1 modest deep ocean. Arctic kelps had highest production capacity, while Pacific greater overall due their higher productivity rates. Our transparent, reproducible represents important step towards accurate accounting forests.
