Abstract Purpose of Review Carbon sequestration and storage in forest ecosystems is often promoted as a solution for reducing CO 2 concentrations the atmosphere. Yet, our understanding lacking regarding how management strategies affect net removal greenhouse gases contribute to climate change mitigation. Here, we present review carbon stock dynamics, following three that are widely used boreal, temperate tropical forests: extensive management, intensive old-growth conservation. Recent Findings Several studies show specific can improve capacity soil storage. Within these studies, conservation strategy results greater soils than do management. Intensive enhances through afforestation using fast-growing species, mechanical preparation from low moderate intensity N fertilization. Extensive an intermediate compromise storage, between strategies. With respect silvicultural treatments, partial cutting practice increases rates maintains higher compared clear-cuts. Each discussed this showed similar effect on all biomes, although magnitude effects differs mainly terms heterotrophic respiration. Summary To achieve sustainable fulfill industrial demand profitability, gaps must be dealt with scientific knowledge context, integration aforementioned functional zoning approach at landscape scale. We promising guiding such global context.

Blue carbon benefits from global saltmarsh restoration

Global Change Biology, Год журнала: 2023, Номер 29(23), С. 6517 - 6545

Coastal saltmarshes are found globally, yet 25%-50% reduced compared with their historical cover. Restoration is incentivised by the promise that marshes efficient storers of 'blue' carbon, although claim lacks substantiation across global contexts. We synthesised data from 431 studies to quantify benefits saltmarsh restoration carbon accumulation and greenhouse gas uptake. The results showed store approximately 1.41-2.44 Pg carbon. Restored had very low (GHG) fluxes rapid accumulation, resulting in a mean net rate 64.70 t CO2 e ha-1 year-1 . Using this estimate potential rates, we find regeneration could result 12.93-207.03 Mt per year, offsetting equivalent up 0.51% energy-related emissions-a substantial amount, considering represent <1% Earth's surface. Carbon rates GHG varied contextually temperature, rainfall dominant vegetation, eastern coasts USA Australia particular hotspots for storage. While study reveals paucity some variables continents, suggesting need further research, offset emissions clear. ability facilitate natural now rests principally on action management-policy community financial opportunities supporting restoration.

Global dataset of soil organic carbon in tidal marshes

Scientific Data, Год журнала: 2023, Номер 10(1)

Опубликована: Ноя. 11, 2023

Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil (SOC) stocks provide an important resource for researchers, natural managers, and policy-makers working towards the protection, restoration, valuation these ecosystems. We collated a global dataset tidal marsh (MarSOC) from 99 studies that includes location, depth, site name, dry bulk density, SOC, and/or matter (SOM). The MarSOC 17,454 points 2,329 unique locations, 29 countries. generated general transfer function conversion SOM to SOC. Using this we estimated median (± absolute deviation) value 79.2 ± 38.1 Mg SOC ha-1 top 30 cm 231 134 1 m soils globally. This can serve as basis future work, may contribute incorporation ecosystems into climate change mitigation adaptation strategies policies.

Capturing of organic carbon and nitrogen in eelgrass sediments of southern Scandinavia

Abstract The ability of seagrass meadows to filter nutrients and capture store CO 2 in the form organic carbon (OC) nitrogen (N) their sediments may help mitigate local eutrophication as well climate change via meadow restoration protection. This study assesses OC N sediment stocks (top 50 cm) sequestration rates within Danish eelgrass meadows. At four locations, eelgrass‐vegetated nearby unvegetated plots were studied protected exposed areas. average cm 2.6 ± 0.3 kg m −2 0.23 0.01 , including vegetated plots.

The implementation of climate change mitigation strategies based on the conservation and restoration Blue Carbon ecosystems requires a deep understanding magnitude variability in organic carbon (Corg) storage across within these ecosystems. This study explored soil Corg stocks burial rates intertidal estuarine habitats Atlantic European coast its relation to biotic abiotic drivers. A total 136 cores were collected saltmarshes located at different tidal zones (high marsh, N = 45; low 30), seagrass meadows (N 17) flats 44), from inner outer sections five estuaries characterized by basin land uses. Soil higher high-marsh communities (65 ± 3 Mg ha-1) than low-marsh (38 ha-1), (40 5 unvegetated (46 whereas also tended be high marshes (62 13 g m-2 y-1) compared (43 15 (35 9 y-1). decreased most reflecting decrease river influence towards estuary mouth.
