Recent attention has focused on the high rates of annual carbon sequestration in vegetated coastal ecosystems—marshes, mangroves, and seagrasses—that may be lost with habitat destruction ('conversion'). Relatively unappreciated, however, is that conversion these ecosystems also impacts very large pools previously-sequestered carbon. Residing mostly sediments, this 'blue carbon' can released to atmosphere when are converted or degraded. Here we provide first global estimates impact evaluate...
Coastal wetlands are sites of rapid carbon (C) sequestration and contain large soil C stocks. Thus, there is increasing interest in those ecosystems as for anthropogenic greenhouse gas emission offset projects (sometimes referred to "Blue Carbon"), through preservation existing stocks or creation new increase future sequestration. Here we show that the globally-widespread occurrence diked, impounded, drained tidally-restricted salt marshes, substantial methane (CH4) CO2 reductions can be...
Significant efforts have been invested to restore mangrove forests worldwide through reforestation and afforestation. However, blue carbon benefit has not compared between these two silvicultural pathways at the global scale. Here, we integrated results from direct field measurements of over 370 restoration sites around world show that (reestablishing mangroves where they previously colonized) had a greater storage potential per hectare than afforestation (establishing mangrove). Greater...
Background Tidal marshes will be threatened by increasing rates of sea-level rise (SLR) over the next century. Managers seek guidance on whether existing and restored resilient under a range potential future conditions, prioritizing marsh restoration conservation activities. Methodology Building upon established models, we developed hybrid approach that involves mechanistic treatment accretion dynamics incorporates spatial variation at scale relevant for decision-making. We applied this...
Coastal ecosystems produce and sequester significant amounts of carbon ("blue carbon"), which has been well documented in humid semi-humid regions temperate tropical climates but less so arid where mangroves, marshes, seagrasses exist near the limit their tolerance for extreme temperature salinity. To better understand these unique systems, we measured whole-ecosystem stocks 58 sites across United Arab Emirates (UAE) natural planted salt seagrass beds, microbial mats, coastal sabkha (inter-...
Abstract Tidal wetlands produce long-term soil organic carbon (C) stocks. Thus for accounting purposes, we need accurate and precise information on the magnitude spatial distribution of those We assembled analyzed an unprecedented core dataset, tested three strategies mapping stocks: applying average value from synthesis to mapped tidal wetlands, models fit using empirical data applied soil, vegetation salinity maps, relying independently generated maps. Soil stocks were far lower varied...
Protecting existing mangrove forests is a priority for global conservation because of the wide range services that these coastal provide to humankind. Despite recent reduction in rates loss, high historical loss mean there are at least 800,000 ha globally potentially suitable re-establishment. Recently deposited mud banks or intertidal, previously terrestrial, land might additional habitat expanding areas locally. There long history rehabilitation. However, despite numerous good examples of,...
The magnitude and pace of global climate change demand ambitious effective implementation nationally determined contributions (NDCs). Nature-based solutions present an efficient approach to achieving mitigation, adaptation resilience goals. Yet few nations have quantified the diverse benefits nature-based evaluate select ecosystem targets for their NDCs. Here we report on Belize's pursuit innovative, evidence-based target setting by accounting multiple blue carbon strategies. Through...
Abstract Aim We developed a set of statistical models to improve spatial estimates mangrove aboveground biomass ( AGB ) based on the environmental signature hypothesis ESH ). hypothesized that higher tidal amplitudes, river discharge, temperature, direct rainfall and decreased potential evapotranspiration explain observed high . Location Neotropics small portion N earctic region. Methods A universal forest model site‐level structure statistics was validated spatially interpolate at different...
The role of coastal blue carbon ecosystems in climate mitigation and adaptation efforts has been recognized. Blue ecosystem functionality is one component nature-based or green–gray infrastructure multifunctionality, which includes contributions by nature to disaster risk reduction, resilience, erosion control, land formation, other services. Here we review how green solutions shallow nearshore areas can contribute change adaptation. We then summarize available types (green, gray, hybrid)...
Accurate, scalable forestry insights are critical for implementing carbon credit-based reforestation initiatives and data-driven ecosystem management. However, existing forest quantification methods face significant challenges: hand measurement is labor-intensive, time-consuming, difficult to trust; satellite imagery not accurate enough; airborne LiDAR remains prohibitively expensive at scale. In this work, we introduce ForestSplat: an monitoring, reporting, verification (MRV) system built...
Seagrass ecosystems are recognized for their capacity to sequester and store organic carbon, but there is large variability in soil carbon stocks associated with plant traits environmental conditions, making the quantification scaling of storage fluxes needed contribute climate change mitigation highly challenging. Here, we provide estimates seagrass systems (biomass soil) through analyses a comprehensive global database including 2700+ cores. The median Corg stock estimate 24.2 (12.4 -...
Abstract Intertidal restoration through realignment of flood defenses has become an important component the U.K. coastal and estuarine management strategy. Although experimentation with recent deliberate breaches is in progress, long‐term prognosis for salt marsh can be investigated at a number sites around Essex, southeast England where marshes have been reactivated (unmanaged restoration) by storm events over past centuries. These historically possess higher creek densities than their...
Sustainable coastal resource management requires the safeguarding and transmission to future generations of a level quality natural resources that will provide an ongoing yield economic environmental services. All maritime nations are approaching this goal with different issues in mind. The UK, which has long history development flood protection areas, chosen adopt shoreline management, rather than so placing defence above all else as its primary statutory objective. This paper aims...
