A global biophysical typology of mangroves and its relevance for ecosystem structure and deforestation

Scientific Reports, Journal Year: 2020, Volume and Issue: 10(1)

Published: Sept. 4, 2020

Mangrove forests provide many ecosystem services but are among the world's most threatened ecosystems. Mangroves vary substantially according to their geomorphic and sedimentary setting; while several conceptual frameworks describe these settings, spatial distribution has not been quantified. Here, we present a new global mangrove biophysical typology show that, based on 2016 extent, 40.5% (54,972 km2) of systems were deltaic, 27.5% (37,411 estuarine 21.0% (28,493 open coast, with lagoonal mangroves least abundant (11.0%, 14,993 km2). also classified setting, carbonate being less than terrigenous, representing just 9.6% coverage. Our provides basis for future research incorporate setting in analyses. We two examples such applications. Firstly, change extent between 1996 2016, all types exhibited considerable declines area, losses (- 6.9%) nearly twice that other types. Secondly, quantify differences aboveground biomass different types, it significantly lower mangroves. Overall, our baseline assessing restoration potential quantifying service provision.

Mangrove forests under climate change in a 2°C world

Wiley Interdisciplinary Reviews Climate Change, Journal Year: 2022, Volume and Issue: 13(4)

Published: June 7, 2022

Abstract The world's nations are committed to keeping global temperature rises less than 2°C avoid the worst impacts of climate change. Such a target is crucial for mangrove forests, because they located primarily in tropical and subtropical regions that expected see large changes climatic conditions; their intertidal location sensitivity environmental conditions means mangroves be on front line change impacts. We conceptualize what world might look like mangroves, particular potential negative positive responses ecosystem anticipated future atmospheric CO 2 concentrations, temperature, sea level, cyclone activity, storminess frequency, magnitude oscillations. also assess spatial distribution such stressors, relative contributions dynamics, discuss challenges attributing dynamics versus other stressors. knowledge can help future‐proof conservation restoration activities, improve Intergovernmental Panel Climate Change's confidence level ascribed highlight key thresholds beyond which certain.

Exploring the Potentials of Halophytes in Addressing Climate Change-Related Issues: A Synthesis of Their Biological, Environmental, and Socioeconomic Aspects

World, Journal Year: 2024, Volume and Issue: 5(1), P. 36 - 57

Published: Jan. 11, 2024

Halophytes are naturally salt-tolerant plants with immense potential to become alternate crops for saline lands. While their economic benefits have gained increasing attention, often, the roles of halophytes in addressing different climate change-related issues overlooked. can be a renewable resource clean ‘carbon-neutral’ energy by serving as biofuel or biogas feedstock, help sequestration rising CO2 well phytoremediation various pollutants, good source food and fodder thereby achieving security arid/saline areas, protection biodiversity conservation ecosystems, provide livelihood poor local communities inhabiting barren This review also attempts highlight usages connection global change perspective. However, there still many challenges such viability, customer preferences, environmental impacts, scale-up challenges, which need further research, innovation, effective policies, collaboration. In general, this provides synthesis biological, environmental, socioeconomic aspects fully exploit human welfare combating changes.

Macroecological patterns of forest structure and allometric scaling in mangrove forests

Global Ecology and Biogeography, Journal Year: 2021, Volume and Issue: 30(5), P. 1000 - 1013

Published: Feb. 27, 2021

Abstract Aim Mangrove wetlands span broad geographical gradients, resulting in functionally diverse tree communities. We asked whether latitudinal variation, allometric scaling relationships and species composition influence mangrove forest structure biomass allocation across biogeographical regions distinct coastal morphologies. Location Global. Time period Present. Major taxa studied ecosystems. Methods built the largest field‐based dataset on to date ( c . 2,800 plots from 67 countries) address macroecological questions pertaining structural functional diversity of mangroves spanning morphology gradients. used frequentist inference statistics machine learning models determine environmental drivers that control within communities globally. Results Allometric complexity were consistent suggesting is controlled by regional forcings rather than latitude or composition. For instance, nearly 40% global variation was explained climate hydroperiod, revealing nonlinear thresholds accumulation Furthermore, we found ecosystem‐level carbon stocks (average 401 ± 48 MgC/ha, covering top 1 m soil) varied little morphologies, reflecting bottom‐up geomorphic controls shape patterns apportioning. Main conclusions Our findings reconcile views wetland terrestrial macroecology. Similarities stand cross‐site size–density multiscale gradients show resource ecosystems independent size invariant latitude. Mangroves follow a universal fractal‐based relationship describes for several other tree‐dominated Understanding how adhere these rules can improve our ability account apportioning response

Perspectives in Ecology and Conservation, Journal Year: 2021, Volume and Issue: 19(3), P. 267 - 278

Published: June 29, 2021

Understanding the impacts on Brazilian semi-arid coast, which is a drought-prone area (>1000 km) in tropical Atlantic, and how ecosystems survive adapt to such extreme environments requires socioecological studies create theory for conservation. Here, we highlight five main ongoing changes areas, namely (1) decrease rainfall rates due climate change, alters freshwater flows, water residence times, promotes hypersalinity (>37) low-inflow estuaries; (2) sea-level rise, groundwater hazards, increased erosion of beaches nearshore mangroves, landward mangrove forest expansion enhanced saline intrusion along river basins; (3) land-ocean fluxes silting closure sandy bars estuarine mouths; (4) warming intensity frequency events (e.g., heat waves, droughts, sea swells); (5) growing eutrophication hypoxia, loss vegetation cover biodiversity urbanization, aquaculture (shrimp farming), agriculture, land-use includes building dams supply. The alteration biogeochemical processes ("Arctic Paradox" hypothesis) acidification that potentialize impact contaminants nutrients also highlighted. These have effects food security multiple trophic levels, should preferentially be studied through long-term approach advancing research. Based these concerns, propose key questions guide research context Decade Ocean Science Sustainable Development (2021–2030) support science-based management actions Brazil other similar areas worldwide.

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.

Ecosystems in inland river basins are crucial for maintaining socioeconomic stability arid regions. As a result, an essential tool tracking ecosystem changes is the measurement of service value (ESV). Using land use Aksu River Basin (ARB) from 2002 to 2021 as example, response variations ESV basin was examined. equivalency coefficients values adapted specific Chinese context, nine different types were assessed using Getis-Ord Gi* statistical technique and Spearman rank correlation analysis. The findings revealed that (1) pattern change ARB has changed significantly over past 20 years, with grassland unused being dominant ARB, both accounting more than 74 % total area study area. Changes dynamics pronounced each type, all exhibiting positive dynamics, except land, which exhibited negative dynamics. (2) increased 48.06 billion yuan 52.59 2011 then decreased 49.37 2021. Grassland main ecological showed increasing decreasing trend. (3) There clear geographical temporal variation distribution, hotspots primarily located northern section coldspots dispersed east-central region. (4) Each type's sensitivity index less 1, showing coefficient (VC) had small impact on ESV.
