Malaysia hosts some of the most productive blue carbon ecosystems globally. Here we review status and known threats faced by local mangroves seagrass examine conservation prospects using financing. Based on lessons learnt from projects worldwide, needs to address governance financing hurdles that include clarifying land tenureship, ensuring community involvement benefits, obtaining sustainable for long-term success. Research clarify uncertainties extent trajectories both mangrove is needed determine baseline scenarios demonstrate additionality in projects.

Forest-fire interactions, impacts, and implications: a focus on mangroves

New Zealand journal of forestry science, Год журнала: 2025, Номер 55

Background: Fire plays a key role in the world’s wetland ecosystems, affecting fundamental aspects of their ecological functioning. The increased frequency wildfires continues to exert significant influence on succession mangrove ecosystems and spatial distribution species. Numerous studies have attempted highlight effect fires forest ecosystem function integrity; however, results are inconclusive. In particular, it remains uncertain whether direct impacts implications type known for its distinct characteristics low ignition rates due high moisture levels. Methods: We conducted comprehensive review over 120 relevant scholarly articles found through formal searches literature citation databases by surveying publications identify examine interactions, prevalence, globally. also synthesised recurrent numerous goods services offered mangroves highlighted existing gaps directions future research. Results: Mangrove prevalent many countries across world with varying distributions forested areas. While there causes mangroves, most occurrences combination natural dry periods (El Niño events) anthropogenic activities, which may deliberately or accidentally increase fire regimes. There negative effects can affect provided environment society, including habitat loss, pollution, wildlife destruction. However, our findings some cases where positive encouraging nutrient enrichment expansion. Our reports priorities research understanding sustainable management coexistence preservation, conservation, public awareness. Conclusions: Forest phenomena human-induced factors. With predominantly effects, result loss integrity, leading severe economic losses degradation. Emphasis should therefore be placed forestry awareness mitigation dynamic ecosystems.

Climate change is a key issue receiving increasing global attention. Coastal areas play an important role in mitigating climate because of enormous potentials for carbon sequestration. Simulating and evaluating the storage, increment, value coastal considerable importance achieving neutrality. In this study, South Coast Hangzhou Bay China was selected as study area. A three-class pool system established based on vegetation soil considering coastline boundary comprehensively revealing sink accurately distinguishing roles different pools. Then, maps storage increment were generated by integrating field remote sensing data through "from point to area" spatial simulations.

Mangroves are well known for their ability to sequester and store a large amount of carbon within plant parts sediment. This characteristic is termed as blue important combat the global warming through sink storage. Studies on remain limited particularly east coast Peninsular Malaysia. Therefore, this study was conducted quantify both above belowground mangrove stock in Setiu Lagoon, Terengganu. In present study, aboveground higher than carbon.

Carbon Stocks in Two Aquatic Marshes on the Caribbean and Pacific Coast of Panama

Climate, Год журнала: 2024, Номер 12(11), С. 171 - 171

Опубликована: Окт. 25, 2024

Wetlands are critical ecosystems globally, boasting significant ecological and economic value. They play a crucial role in the hydrological cycle by storing water carbon, thereby helping to mitigate climate variability. But Panama, little is known about carbon stored freshwater wetlands. This research presents estimation of stocks two wetlands located on both sides Caribbean (Portobelo) Pacific (Tonosi) coasts. The methodology consisted transects 125 m 40 wide, with six circular plots every 25 m; each transect, diameter tree trunk was measured at breast height (1.3 m) species recorded, same plots, soil samples were collected triplicate depth intervals. average total ecosystem storage (TECS) for aquatic Tonosí 106.26 ± 18.3 Mg C ha−1, Portobelo, it 355.09 70.02 ha−1. These recorded values can contribute conservation wetlands, supporting Panama’s nationally determined NDC contributions. However, despite acceptance that important nature-based solutions, national data still scarce their protection should be increased.
