“…Consistently with organic matter content variability, carbon stock estimates were highly variable across different marshes, ranging between 9,800 and 24,700 ton C km -2 (17,108 ± 5,757 ton C km 2 ), with higher values generally occurring at the landward side of the lagoon boundaries ( Although some of the variability among global compilations may be due to methodological differences, our results suggest that the sedimentary history and the environmental conditions within a tidal system may generate variable and site-specific carbon accumulation patterns, enhancing blue carbon assessment complexity. Importantly, the values estimated in our study are comparable to carbon stock estimates attributed to temperate and tropical forests (24,300 and 15,300 ton C km -2 , respectively, (45)) and support the great potential of salt-marshes as efficient carbon sinks. High content of organic carbon found deep in salt-marsh soils, with well-preserved plant debris dating back hundreds of years (35), further confirms salt-marsh potential to sequester carbon over long temporal scales and thus the eligibility of their carbon offsets for greenhouse gas markets.…”

Salt marshes are intertidal coastal ecosystems shaped by complex feedbacks between hydrodynamic, morphological, and biological processes. These crucial yet endangered environments provide a diverse range of ecosystem services but are globally subjected to high anthropogenic pressures, while being severely exposed to climate change impacts. The importance of salt marshes as ‘blue carbon’ sinks, deriving from their primary production coupled with rapid surface accretion, has been increasingly recognized within the framework of climate mitigation strategies. However, large uncertainties remain in salt-marsh carbon stock and sequestration estimation. In order to provide further knowledge in salt-marsh carbon assessment and investigate marsh carbon pool response to management actions, we analysed organic matter content in salt-marsh soils of the Venice Lagoon (Italy) from 60 sediment cores to the depth of 1 m and estimated organic carbon stock and accumulation rates in different areas. Organic carbon stocks and accumulation rates were highly variable in different marshes, being affected by organic and inorganic inputs and preservation conditions. Our estimates suggest that the studied marshes can absorb the same amount of carbon as 130,000 trees. However, flood regulation may reduce by 33% the annual marsh CO2 sequestration potential.

“…For each core, soil samples were taken at 12 depths (0, 5,10,15,20,25,30,35,40,45,50, 75 cm from the surface, see 57) and subsamples were prepared for different analyses, including soil density, organic matter and carbon content.…”

“…In accordance, scientists advise taking control of greenhouse gas emissions, low carbon economy, development of renewable resources, technological changes, and forestation for stopping global temperature rise [ 7 ]. Being aligned with the Paris Agreement, UK and France have already set an aim to “net-zero” emissions by 2050 [ 8 ]. As an adaptation, efforts are in place for decreasing fossil energy consumption [ 9 ], greater attention has been put on optimal management and use of natural resources [ 10 ] along with the development of renewable resources.…”

Global warming as a result of climate change has become a major concern for people all over the world. It has recently drawn the attention of the entire conscious community, with the fear that if not addressed properly, it will result in the extinction of numerous species around the world. At the same time, it will pose a threat to human health, food security, living environment and standard of living. Thereby, possible solutions are being explored accordingly; regulations have been imposed in places binding green production practices, limiting the emission of CO 2 and emphasis is given on renewable resources along with the search for alternatives to carbon-positive materials. Cannabis sativa L. (hemp) has received a lot of attention because of its multipurpose usability, short production cycle, low capital demand in cultivation, possibility of carbon-negative transformation and easy carbon sequestering material. This paper reviews hemp as a very promising renewable resource including its potential uses in paper, textiles, composites, biofuel, and food industry.
