In coastal areas around the world, dominant primary producers are benthic macrophytes, including seagrasses and macroalgae, that provide habitat structure food for diverse abundant populations communities, drive ecosystem processes. Seagrass meadows macroalgal forests economically central to human particularly in developing contributing fisheries yield, storm protection, blue carbon storage, important cultural values. These services threatened worldwide by activities, with substantial of seagrass kelp lost over last half-century. Tracking status trends marine macrophyte cover quality is an emerging priority ocean management, but doing so has been challenged limited coordination across numerous efforts monitor which vary widely goals, methodologies, scales, capacity, governance approaches, data availability. Here, we present a consensus assessment recommendations on current state opportunities advancing global observations, integrating contributions from community researchers broad geographic disciplinary expertise. The time ripe harmonize observations building existing networks identifying core set common metrics approaches sampling design, field measurements, taxonomy, governance, capacity building, management. A observation would then be facilitated ensuring rigorous documentation, archiving open-access sharing protocols resources at all stages workflow, surveys provision data. Realizing these will produce more effective, efficient, responsive observing, accurate picture change systems, stronger international sustaining observations.

Seagrasses are remarkable plants that have adapted to live in a marine environment. They form extensive meadows found globally bioengineer their local environments and preserve the coastal seascape. With increasing realization of planetary emergency we face, there is growing interest using seagrasses as nature-based solution for greenhouse gas mitigation. However, seagrass sensitivity stressors acute, many places, risk loss degradation persists. If ecological state remains compromised, then ability contribute solutions climate biodiversity crisis doubt. We examine major role play how rethinking conservation critical understanding part fighting our emergency.

The concurrent pressures of rising global temperatures, rates and incidence species decline, emergence infectious diseases represent an unprecedented planetary crisis. Intergovernmental reports have drawn focus to the escalating climate biodiversity crises connections between them, but interactions among all three been largely overlooked. Non-linearities dampening reinforcing make considering interconnections essential anticipating challenges. In this Review, we define exemplify causal pathways that link change, loss, disease. A literature assessment case studies show mechanisms certain pairs are better understood than others full triad is rarely considered. Although challenges evaluating these interactions—including a mismatch in scales, data availability, methods—are substantial, current approaches would benefit from expanding scientific cultures embrace interdisciplinarity integrating animal, human, environmental perspectives.

Societal Impact Statement Seagrass ecosystems are of fundamental importance to our planet and wellbeing. Seagrasses marine flowering plants, which engineer that provide a multitude ecosystem services, for example, blue foods carbon sequestration. have largely been degraded across much their global range. There is now increasing interest in the conservation restoration these systems, particularly context climate emergency biodiversity crisis. The collation 100 questions from experts Europe could, if answered, improve ability conserve restore systems by facilitating shift success such work. Summary meadows numerous services including biodiversity, coastal protection, In Europe, seagrasses can be found shallow sheltered waters along coastlines, estuaries & lagoons, around islands, but distribution has declined. Factors as poor water quality, modification, mechanical damage, overfishing, land‐sea interactions, change disease reduced coverage Europe’s necessitating recovery. Research, monitoring efforts on seagrass mostly uncoordinated biased towards certain species regions, resulting inadequate delivery critical information management. Here, we aim identify priority questions, addressed would strongly advance monitoring, research Europe.

Stocks and losses of soil organic carbon from Chinese vegetated coastal habitats

Global Change Biology, Journal Year: 2020, Volume and Issue: 27(1), P. 202 - 214

Published: Sept. 25, 2020

Abstract Global vegetated coastal habitats (VCHs) represent a large sink for organic carbon (OC) stored within their soils. The regional patterns and causes of spatial variation, however, remain uncertain. sparsity bias studies on soil OC stocks from Chinese VCHs have limited the reliable estimation capacity as global sinks. Here, we use field published data 262 sampled cores 181 surface soils to report estimates stocks, burial rates losses in China. We find that mangrove, salt marsh seagrass relatively low storing 6.3 ± 0.6, 7.5 1.6 0.6 Tg C (±95% confidence interval) top meter profile with 44 17, 159 57, 6 45 Gg C/year, respectively. variability is linked biogeographic factors but mostly impacted by sedimentary processes anthropic activities. All experienced significant losses, resulting estimated emissions 94.2–395.4 CO 2 e (carbon dioxide equivalent) over past 70 years. Reversing this trend through conservation restoration measures has, therefore, great potential contributing mitigation climate change while providing additional benefits. This assessment, national scale highly environments under intensive anthropogenic pressures, provides important insights into blue mechanism sequestration capacities, thus synchronous progression management.
