Published: July 12, 2020

Global mangrove loss has been attributed primarily to human activity. Anthropogenic hotspots across Southeast Asia and around the world have characterized ecosystem as highly threatened, though natural processes such erosion can also play a significant role in forest vulnerability. However, extent of threats not fully quantified at global scale. Here, using Random Forest-based analysis over one million Landsat images, we present first 30 m resolution maps drivers from 2000 2016, capturing both human-driven stressors. We estimate that 62% losses between 2016 resulted land-use change, through conversion aquaculture agriculture. Up 80% these occurred within six Asian nations, reflecting regional emphasis on enhancing for export support economic development. Both anthropogenic declined slower declines caused an increase their relative contribution total area. attribute decline regionally dependent combination increased conservation efforts lack remaining mangroves viable conversion. While restore protect appear be effective decadal timescales, emergence presents immediate challenge coastal adaptation. anticipate our results will inform decision-making restoration initiatives by providing locally relevant understanding causes loss.

Drivers of global mangrove loss and gain in social-ecological systems

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: Oct. 26, 2022

Abstract Mangrove forests store high amounts of carbon, protect communities from storms, and support fisheries. Mangroves exist in complex social-ecological systems, hence identifying socioeconomic conditions associated with decreasing losses increasing gains remains challenging albeit important. The impact national governance conservation policies on mangrove at the landscape-scale has not been assessed to date, nor have interactions local economic pressures biophysical drivers. Here, we assess relationship between variables change across coastal geomorphic units worldwide 1996 2016. Globally, find that drivers loss can also be gain, changed over 20 years. association growth appears reversed, shifting negatively impacting mangroves first decade enabling expansion second decade. Importantly, community forestry is promoting expansion, whereas conversion agriculture aquaculture, often occurring protected areas, results loss. Sustainable development, forestry, co-management areas are promising strategies reverse losses, capacity human-livelihoods combat climate change.

Published: Sept. 29, 2022

Mangrove ecosystems provide critical goods and ecosystem services to coastal communities contribute climate change mitigation. Over four decades, remote sensing has proved its usefulness in monitoring mangrove on a broad scale, over time, at lower cost than field observation. The increasing use of spectral indices led an expansion the geographical context studies from local-scale intercontinental global analyses past 20 years. In sensing, numerous derived multiple bands remotely sensed data have been developed used for mangroves. this paper, we review range produced utilised between 1996 2021. Our findings reveal that variety aspects but excluded identification species. included are extent, distribution, above ground parameters (e.g., carbon density, biomass, canopy height, estimations LAI), changes aforementioned time.

Mangroves are an important ecosystem that provides valuable social, economic, and environmental services. Indonesia has placed mangroves on its national priority agenda in effort to sustainably manage this achieve climate commitments. However, mangrove management is faced with complex challenges encompassing ecological, economic issues. In order the government’s commitments targets regarding restoration conservation, in-depth study critical review of was conducted herein. This work aimed provide a comprehensive analysis strategic recommendations for sustainable Indonesia. SWOT carried out understand strengths, weaknesses, opportunities, threats related To address these gaps, we reviewed existing policies, current rehabilitation practices, challenges, research technology implementations field. We found strategies protection, such as improving function value forests, integrating management, strengthening political law enforcement, involving all stakeholders (especially coastal communities), advancing innovations, crucial support blue carbon agenda.

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.

Seascape ecology, the marine-centric counterpart to landscape is rapidly emerging as an interdisciplinary and spatially explicit ecological science with relevance marine management, biodiversity conservation, restoration. While important progress in this field has been made past decade, there no coherent prioritisation of key research questions help set future agenda for seascape ecology. We used a 2-stage modified Delphi method solicit applied from academic experts ecology then asked respondents identify priority across 9 interrelated themes using 2 rounds selection. also invited senior management/conservation practitioners prioritise same questions. Analyses highlighted congruence discrepancies perceived priorities research. Themes related both concepts management practice, those identified include change, connectivity, spatial temporal scale, ecosystem-based technologies metrics. Highest-priority (upper tercile) received 50% agreement between respondent groups, lowest (lower 58% agreement. Across all 3 tiers, 36 55 were within ±10% band present most determined by proportion votes received. For each theme, we provide synthesis challenges potential role These serve roadmap advancing during, beyond, UN Decade Ocean Science Sustainable Development (2021-2030).
