Mangroves stand out as one of the most diverse and biologically significant natural systems in world. Playing critical roles maintaining health productivity coastal ecosystems, mangroves provide a range services functions, including habitat for local fauna flora, food other goods, carbon sequestration, protection from disasters such storm surges erosion. It is also evident that face several threats, which have already led to gradual depletion mangrove areas worldwide. Based on analysis current related historical literature data, this review summarises functions threats challenges associated with management practices. Our findings suggest development, expanded aquaculture, deforestation, climate change, implications eutrophication, diseases, pollution are major factors posing sustainability. We highlight various challenges, land use conflict, lack stringent regulatory actions, inadequate policy government frameworks, community awareness, underlie ineffective management. The implementation inclusive coordinated approaches involving stakeholders different backgrounds interests, governmental non-governmental organisations, academia essential restoration sustainable by adapting mitigation strategies.

The Lower Mekong Region (LMR) faces significant loss of mangrove forests, yet limited studies have explored this decline in the region. Here, we employ Google Earth Engine and Landsat satellite imagery to assess changes forest cover across Myanmar, Thailand, Vietnam, Cambodia between 1989 2020, with a five-year interval. Accordingly, estimated carbon stock due cover. Our analysis yielded an overall average accuracy 92.10% kappa coefficient 0.89 four countries. findings reveal 0.9% increase area 2.5% 1.3% Cambodia, while Vietnam experienced 0.2% annually 2020.

Planning hydrological restoration of coastal wetlands: Key model considerations and solutions

The Science of The Total Environment, Год журнала: 2024, Номер 915, С. 169881 - 169881

Опубликована: Янв. 6, 2024

The hydrological restoration of coastal wetlands is an emerging approach for mitigating and adapting to climate change enhancing ecosystem services such as improved water quality biodiversity. This paper synthesises current knowledge on selecting appropriate modelling approaches projects. selection a based project-specific factors, costs, risks, uncertainties, aligns with the overall project objectives. We provide guidance model selection, emphasising use simpler less expensive when appropriate, identifying situations models may not be required managers make informed decisions. recognises supports widespread in by bridging gap between science practices. It underscores significance objectives, budget, available data offers decision-making frameworks, decision trees, aid matching methods specific outcomes.

Resilience to Hurricanes Is High in Mangrove Blue Carbon Forests

Global Change Biology, Год журнала: 2025, Номер 31(3)

Опубликована: Март 1, 2025

ABSTRACT Mangrove forests are typically considered resilient to natural disturbances, likely caused by the evolutionary adaptation of species‐specific traits. These ecosystems play a vital role in global carbon cycle and responsible for an outsized contribution burial enhanced sedimentation rates. Using eddy covariance data from two coastal mangrove Florida Coastal Everglades, we evaluated impact hurricanes have on forest structure function measuring recovery pre‐disturbance conditions following Hurricane Wilma 2005 Irma 2017. We determined “recovery debt,” deficit ecosystem disturbance, using leaf area index (LAI) net exchange (NEE) dioxide (CO 2 ). Calculated as cumulative deviation conditions, debt incorporated recapture all lost due disturbance. In Everglades forests, LAI returned levels within year, respiration maximum photosynthetic rates took much longer, resulting initial 178 g C m −2 at tall with limited impacts scrub forest. At landscape scale, was 0.40 Mt C, most recovered just 4 years. While high‐intensity storms could prolonged subtropical fast canopy suggests these will remain strong sinks.

Coastal Restoration Challenges and Strategies for Small Island Developing States in the Face of Sea Level Rise and Climate Change

Coasts, Год журнала: 2024, Номер 4(2), С. 235 - 286

Опубликована: Апрель 1, 2024

The climate crisis poses a grave threat to numerous small island developing states (SIDS), intensifying risks from extreme weather events and sea level rise (SLR). This vulnerability heightens the dangers of coastal erosion, chronic water quality degradation, dwindling resources, demanding global attention. resultant loss ecological persistence, functional services, ecosystem resilience jeopardizes protection against wave action SLR, endangering habitats’ economic value, food security, infrastructure, livelihoods. Implementing integrated strategies is imperative. A thorough discussion available best management practices for restoration presented in context SIDS needs, threats, major constraints. Solutions must encompass enhanced green infrastructure (coral reefs, seagrass meadows, mangroves/wetlands, urban shorelines), sustainable development practices, circular economy principles, adoption policies. requires securing creative funding, promoting job creation, fostering local stakeholder engagement. Tailored each island’s reality, solutions overcome socio-economic, logistical, political obstacles. Despite challenges, timely opportunities exist habitat change adaptation Integrated spanning disciplines stakeholders necessitate significant will.

Oceans play a vital role in socioeconomic and environmental development by supporting activities such as tourism, recreation, food provision while providing important ecosystem services. However, concerns have been raised about the threat that climate change poses to functions of oceans. This study examines impacts, threats, adaptation strategies marine biodiversity. Using bibliometric secondary data analysis, this determines leads rising sea temperatures, heatwaves, acidification, increasing levels. These factors undermine significance ocean also identifies significant risks posed species diversity distribution, primarily through habitat degradation shifts ranges. Scholarly focus on these challenges has grown over time, focusing building resilience mitigate adverse impacts. critically evaluates various measures, including nature-based human-based solutions restoration, policy legislative frameworks, their potential protect ecosystems.

Abstract Mangrove forests being the abode of diverse fauna and flora are vital for healthy coastal ecosystems. These act as a carbon sequester protection shield against floods, storms, cyclones. The mangroves Sundarban Biosphere Reserve (SBR), one most dynamic productive ecosystems in world constant degradation. Hence, habitat suitability assessment mangrove species is paramount significance its restoration ecological benefits. study aims to assess prioritize targets 18 true using 10 machine-learning algorithm-based models SBR. We identified degraded areas between 1975 2020 by Landsat images field verification. reserve was divided into 5609 grids 1 km gird size understanding nature degradation collection occurrence data. A total 36 parameters covering physical, environmental, soil, water, bio-climatic disturbance aspects were chosen assessment. Niche overlay function grid-based classes used identify species-based grids. Habitat analysis revealed that nearly half highly suitable Reserve. Restoration within could be achieved covered with less than 75 percent lesser anthropogenic disturbance. calls devising effective management strategies monitoring conserving cover.

The permitting process for marine and coastal restoration: A barrier to achieving global restoration targets?

Conservation Science and Practice, Год журнала: 2023, Номер 5(12)

Опубликована: Ноя. 20, 2023

Abstract To meet global restoration targets, action is needed at a large scale, and high level of ambition. Coastal marine may be hindered by an array factors, including governance: in particular, the cost time associated with obtaining permits. We interviewed small group practitioners Australia to further explore this permitting issue. Our study revealed deeper problem, legal process driving outcomes. Some proponents are turning away from sites highest potential, instead choosing based on ease also found that only one part progress being hampered onerous post‐approval conditions, ongoing liability for restorative interventions. Finally, stifles innovation creativity as outcomes locked‐in permit stage. conclude highlighting urgent need reform processes restoration, current practice put achievement targets risk. It anticipated these findings will interest navigating space, well policymakers.
