Mangrove biomass was traditionally appreciated as a major ecosystem good, but its importance in the coastal carbon budget has been recently highlighted [10, 11, 49, 56, 57]. In other areas such as Punta Yarumal where mangrove trees have been selectively logged, A. aureum formed clumps in the understory. This figure is, in absolute terms, rather ... global biodiversity and the effects thereof will have a worldwide impact. Annual population growth rate (1993–2005) in this municipality (7.2%) is threefold compared to state- and national-level figures [43]. The world is losing its mangroves at a faster rate than global deforestation, the United Nations on 29 September 2014 revealed, adding that the destruction of the coastal habitats was costing billions in economic damages and impacting millions of lives. These figures may be more variable and dramatic at a subcountry level, bearing in mind that coarse-scale inventories using satellite imagery tend to overestimate mangrove cover due to low spatial resolution and heavy cloud cover (as observed in many areas of the Pacific coast and the Urabá region in the Caribbean coast) [14]. This isn’t just a case of creatures being forced to ‘flee’ destruction. The Mangroves of Kenya: Introduction. Mangrove forests in the region were lost at an average rate of 0.18% per year. Yet most of the information about deforestation remains as grey literature [15–18, 21], and, unfortunately, quantitative assessments of mangrove deforestation (using both follow-up remote sensing and field inventories) at a subnational level are scant and limited to strategic ecoregions such as the Ciénaga Grande de Santa Marta [22]. Trees of the mangrove Avicennia africana which once probably covered the patch can be seen in the background. The objective of this paper was to summarize the impacts of both threats on forest structure, species composition, aboveground biomass and carbon reservoir, species introgressions, and benthic fauna populations by collating past and current data and by using an interdisciplinary approach in the Urabá Gulf (Colombia) as a case study.

These results suggest that mangrove deforestation exerts marked effects on fish assemblages. Despite the tourism activities of the region, this region may be considered a cold spot of deforestation compared to the national average computed during the same period (1.3%, according to [13]). In addition to the economic problems posed by mangrove deforestation, the report, entitled The Importance of Mangroves: A Call to Action, also cautions that a continued reduction in the surface area of mangrove forests would inevitably expose coastal environments to the harmful effects of climate change. You can view samples of our professional work here. Nonetheless, Laguncularia pollen and Acrostichum spore records underscore the prevalence of human and natural disturbances in Caribbean mangroves, because pollen and spores are widespread distributed by water and air [70]. Extraction of poles from R. mangle trees with DBH < 15 cm has also been reported from Venezuela [53]. 6. Macintosh, D.J. (Food and Agriculture Organization of the United Nations), “The world’s mangroves 1980–2005,” FAO Forestry Paper 153, FAO, Rome, Italy, 2007. Deforestation rates in mangroves are four times greater than those in terrestrial tropical rain forests. H. Sánchez-Páez, R. Álvarez-León, F. Pinto-Nolla et al., “Diagnóstico y Zonificación Preliminar de los Manglares del Caribe de Colombia,” Proyecto. Princeton U.P. The Urabá Gulf (also known as the Darién Ecoregion) is the southernmost location of mangroves in the Caribbean basin (Figure 1), where presumably well-developed and extensive mangrove stands are found, exceeding the figures observed along the Caribbean coasts of Costa Rica, Panamá, and Southern Colombia [18, 37, 38]. < In addition to selective logging, basin mangroves are cleared for understory cattle ranching and for establishing pastures (Figure 4). CORPOURABA, “Caracterización y zonificación de los manglares del Golfo de Urabá-Departamento de Antioquia,” Proyecto Zonificación y Ordenamiento de los manglares de Urabá, Convenio 201671, FONADE-CORPOURABA, Apartadó, Colombia, 2003. Limnology and Oceanography 41 (1): 169–176. Introduct The Mangrove Ecosystems for Climate Change Adaptation and Livelihoods (MESCAL) project is a four-year project (2010-2013) funded by the German Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU). No correlation was observed between the selective logging of A. germinans and the IVI of L. racemosa in basin mangroves, contrary to the observed in Belizean [64] and Puerto Rican [66] mangroves. (eds), Wetlands of Kenya. Day, J.H. Workshop on Wetlands Conservation. R. mangle is predominantly exploited for poles, but their commerce is poorly attractive [42], as evidenced by the piles commonly abandoned in informal markets, streets, or even in the field. Area and structure parameters (mean values) for mangroves in the Urabá Gulf. In addition, cattle ranching has been a major economic activity since the early 20th century. Journal of Ecology 50: 19–34. volume 2, pages75–83(1998)Cite this article. Aquaculture was a major pressure on mangrove systems during this period, but its dominance was lower than expected, contrary to popular development narratives. All about deforestation in Bangladesh including causes, effects, and possible solutions are discussed below: 50% of the country’s forests have been destroyed in the last 20 years. Mangrove development is probably boosted by the large freshwater discharge of the Atrato River (Q = 4,155 m3/s, the second largest in the Caribbean Coast of Colombia, after the Magdalena River), fed by the heavy rain of the Chocó Region, one of the world’s highest. We examined the effects of mangrove deforestation on coral reefs using shoreline mangrove density, near-shore nitrate levels, and algal coverage on adjacent reefs. = Deforestation alters forest structure and species composition [13].

This study quantifies the proximate drivers (i.e., replacement land uses) of mangrove deforestation across Southeast Asia between 2000 and 2012. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. However, as stated by Bouillon et al. The ‘borders’ that demarcate human settlements with newly-destroyed forest are actually attractive to animal life. In addition to the limited information about rates and drivers of mangrove deforestation, there is a lack of understanding on how specific activities such as selective logging and mangrove reclamation have impacted forest structure, faunal diversity, and services to humans, particularly in the Neotropics. In the Urabá Gulf, selective logging and land reclamation, in addition to coastline erosion, have reduced mangrove area, but it has particularly altered natural patterns of forest structure and species composition. The early inventories conducted in the most pristine areas (Atrato River Delta and Rionegro Cove) revealed that self-thinning was the most evident driver of structure in red mangrove stands ( Authors; Authors and affiliations; Tatsuya Shinnaka; Mitsuhiko Sano; Kou Ikejima; Prasert Tongnunui ; Masahiro Horinouchi; Hisashi Kurokura; Article.

For a long time there has been huge uncertainty in rates of mangrove deforestation (Friess & Webb 2011; 2014), but remote sensing tools have allowed us to quantify mangrove … Selective logging of R. mangle and clear-cutting of basin mangroves promoted introgressions by L. racemosa and the mangrove fern A. aureum in periurban sites, and they were a clear sign of cryptic ecological degradation. Smithsonian Institution Press, Washington, D.C., London. MSc. . We examined the effects of mangrove deforestation on … The mangroves of the Eastern African region. Such a population growth has been powered by the profitable banana industry comprising 50359 ha of plantations and exports scoring 55.1 millions of cases [44]. Mangrove species: Rm: Aboveground (area-weighed) carbon and biomass in mangroves in the Urabá Gulf. A. Guevara-Mancera, A. Zamora-Guzmán, H. Rodríguez-Cruz, and H. E.

Indiscriminate felling of trees in the greater parts of Dhaka, Mymensingh, Rajshahi, Rangpur, and Dinajpur has resulted in an alarming depleting of the forests. . As a reference, R. mangle tree diameter was logarithmically skewed towards small values, with a few trees with diameter at breast height (DBH) > 30 cm, in isolated fringing mangroves (Atrato River delta, Rionegro Cove, and Puerto Cesar-Punta Coquito). This is in agreement with Richards and Friess in their assessment of the drivers of mangrove deforestation in Southeast Asia over the period 2000-2012. Jones, D.A. Quantification of deforestation rates and land cover and land use transitions has been impeded by the lack of robust mangrove cover maps. Extinctions and invasions in species-poor mangrove in the Neotropics are expected to bring notorious ecosystem-wide effects [75]. Therefore, conservation efforts should prevent clearing mangroves in the Atrato River delta in order to avoid releasing significant amounts of carbon to the atmosphere and to the ocean, thus negatively impacting the Gulf’s budget. We hypothesized that, as a consequence of N. virginea decline, sediment bioturbation and mangrove litter decomposition would be reduced. Effects Of Mangrove Destruction In Mumbai Environmental Sciences Essay. These early inventories evidenced that mangroves in the Urabá Gulf were dominated by the red mangrove Rhizophora mangle in most locations while Laguncularia racemosa (white mangrove) and Avicennia germinans (black mangrove) coexisted at lower relative densities. Sasekumar, A. 1988. For instance, in Quintana Roo (México) an annual deforestation rate of 0.85% (1995–2007) for fringing mangroves was mostly driven by low-density human settlements and road construction [24]. Ecology and productivity of Malaysian mangrove crab populations (Decapod: Brachyura). The IUCN Wetlands Programme. Anthropogenic development reduces the island's mangrove forests, threatening the health of surrounding coral reefs. Richards, D. R., and Friess, D. A.

On the other hand, charcoal production is a common practice, but it is time consuming and poorly rewarded, because a sack is sold at 4 USD (COP 8,000), although it requires logging and burning 20 trees (Figure 4). In addition, mangroves along Eastern Coast and the northeastern vicinity of Urabá Gulf have probably shrunken as a consequence of the steady coastline retreat experienced (1–50 m/yr; [45]). 1996. , The report indicates that the effects of climate change could result in a loss of a further 10 - 15 per cent of mangroves by year 2100. In conclusion, selective (noncommercial and unplanned) logging in Urabá Gulf mangroves, particularly in the Eastern Coast, already shows signs of unsustainability, and it is worsened by the rapid mangrove conversion to pastures. Zonation and distribution of Creek and fringe mangroves in the semi-arid Kenyan coast. 2009a). Martens, E.E. A recent study in Cispatá Lagoon System (Caribbean coast of Colombia) agreed that the high proportion of Laguncularia pollen may indicate the prevalence of anthropogenic disturbances on mangrove stands otherwise dominated by Rhizophora or Avicennia [69]. Deforestation negatively affects benthic communities; however, there are a few accounts on the direct and indirect impacts and mechanisms. Nonetheless, there is no doubt that this region is a deforestation hotspot in the Caribbean coast of Colombia, as evidenced by the field inventory, and observed human uses (see Section 3). 0 0 Mangrove deforestation drivers in the Colombian Caribbean coast may be similar to the observed in the Greater Caribbean Basin [16, 23], although rates seem to be lower than the few published examples from México and Panamá, two major Latin American hotspots [13]. The report recommends several measures to conserve and restore mangroves. Journal of Animal Ecology 43: 51–69. Dahdouh-Guebas and Koedam [34] proposed that a transdisciplinary approach is required in order to advance in the knowledge of complex issues such as deforestation and climate change in mangroves. For instance, clearing pneumatophores in small-scale deforestations for building walkways and trails was correlated with a decline in density and species richness in the entire community, particularly on gastropods [87]. Mangroves in the Eastern Coast have been decimated and have produced unskewed tree-diameter (DBH) distributions due to the overexploitation of Rhizophora mangle for poles (DBH range: 7–17 cm) and of Avicennia germinans for planks and pilings (DBH Micheli, F., Gherardi, F. and Vannini, M. 1991. Other more striking effects of mangrove deforestation include a decreased availability of wood, fish and prawn, less revenue paid to government in terms of royalties and tourist fees, an increase in coastal erosion and eventual reduction of seagrasses and coral reefs. 1974. MSc. Deforestation and hydrological changes are the most devastating to soil nutrient-plant relations and mangrove productivity. These include creating a global mangrove fund, … 78: 191–198. 2 A guide to marine life of south African shores. Nairobi. UNEP Publication ISBN 92-807-1348-5. Although this reduction was evidently influenced by deforestation in the region, it was seemly biased by differences in the remote sensing techniques employed in both surveys. Study of the meiobenthos in five mangrove vegetation types in Gazi Bay, Kenya. 2 There are also natural threats that contribute to mangrove deforestation such as soil erosion. J. F. Blanco, E. A. Estrada, L. F. Ortiz, L. E. Urrego, "Ecosystem-Wide Impacts of Deforestation in Mangroves: The Urabá Gulf (Colombian Caribbean) Case Study", International Scholarly Research Notices, vol. Mangrove forests are among the most threatened habitats in the world, and mangrove loss is rampant across the globe. Moreover, the codominance of secondary mangrove species or antagonistic distributions can be indicators of cryptic ecological degradation (Dahdouh-Guebas et al. Mangroves and Salt Marshes 1996. This species is a grazer and a facultative detritivore, and given its high density and biomass (range: 16–100 ind./m2; 11.9–74.3 g/m2; [40]), it seems to be responsible for the rapid processing of black mangrove (A. germinans) leaflitter (A. Taborda and J. F. Blanco in preparation). . It is intuitively accepted that deforestation depletes aboveground carbon reservoirs. Effects of mangrove deforestation on mangrove mud crab fishery: Ngomeni-Malindi, Kenya by Esther Fondo (2012-07-23): Books - (eds), Hydrobiology of the mangal. Changes in patterns of macrofaunal distribution in mangrove ecosystems at the Kenyan coast due to natural and un-natural causes. In addition, since specific ecosystem services are provided by particular mangrove species and physiognomies [7], the observed patterns and rates of selective logging and reclamation in the Urabá Gulf will probably produce negative feedbacks in human populations deriving direct and indirect services from mangroves. By 2003, it was estimated that 6993 ha of mangroves existed in the Urabá Gulf using satellite images [17, 42]. Kitheka, J.U. Anthropogenic development reduces the island's mangrove forests, threatening the health of surrounding coral reefs.

Colombia’s Caribbean Coast harbors 88250 ha of mangroves strongly threatened by human activities [15–18]. South American mangroves exhibit the lowest rates compared to Asia, Africa, Northern and Central America; however, a high regional variability is observed, and hotspots do exist [13]. Thesis. 89–109.

Achetez neuf ou d'occasion Coastal Wetland Utilization. Although ethnoecological studies have been instrumental for reconstruction of past uses of mangroves and impacts derived [8, 46, 47, 54], more studies are urged for the Neotropics because a few case studies exist (e.g., Mexico: [55], Venezuela: [53]) and most of the examples concentrate in the Indopacific [6]. Selective logging and conversion to pastures have negative effects in forest structure and species composition, above-ground biomass and carbon reservoir, invasiveness, and benthic fauna in the Urabá Gulf mangroves. Historical information about mangrove cover and structure and detailed data obtained during a recent scientific survey were summarized. Informe principal,” Contrato No 056/88, INDERENA REGIONAL ANTIOQUIA-ECOFOREST, Turbo, Colombia, 1990. Provisioning services are the most commonly appreciated and include sources of timber, fibers and nonwoody products, fuels (firewood and charcoal), food (fisheries), biochemical products, and freshwater; however, the role of mangroves in climatic and hydrologic modulation, erosion control, protection against natural hazards, soil formation, and nutrient cycling has been recently recognized. The objective of this paper was to answer the following questions. Such practices in mangroves and coastal-plain forests are responsible for high annual deforestation rates (1.9% [51]) exceeding those observed in Colombian terrestrial forest hotspots [52]. Introgressions (cryptic ecological degradation) by L. racemosa and Acrostichum aureum (mangrove fern) and low densities of otherwise dominant detritivore snails (Neritina virginea) were observed in periurban basin mangroves. Another threat to mangroves is the over harvesting of marine life populations that put species in danger of becoming extinct or at least non-existent in that area. Bogotá D.C., Colombia, 2000. © 2020 Springer Nature Switzerland AG. A total of 53 REM mangroves were established as part of the initial training and follow-up activities. Gastropods in the Caribbean and elsewhere have been pointed as key detritivores and sediment grazers, even outweighing the role of crabs [80–82]. and Dor, I. University of Nairobi. These mangroves have been converted to agricultural lands, shrimp aquaculture ponds, and urban development (mostly for tourism). The association Pterocarpus-Acrostichum-Laguncularia has been well documented in Puerto Rico [66, 67]. 2012, Article ID 958709, 14 pages, 2012., 1Instituto de Biología, Universidad de Antioquia, Medellín, Colombia, 2Departamento de Ciencias Forestales, Universidad Nacional de Colombia, Medellín, Colombia. 4th edition. 98–116. 0 Despite the many services offered by mangroves worldwide, deforestation as a consequence of overexploitation of woody products and land reclamation is the most important threat [1–3], although a great local variation is observed [12, 13]. Given the clumped distribution of N. virginea, the percent of sampling quadrats with snails was a reliable indicator of impact due to selective logging and of “edge effect” in the mangrove-pasture transition (Figures 6(b) and 6(c); [41]). According to this effort, mangrove cover was estimated in 4908 ha, thus suggesting a reduction in 2085 ha (29.8%) between 2003 and 2009 (estimated annual rate: 4.9%). 1–18.

The practice of mangrove restoration is grounded in the discipline of restoration ecology, which aims to “[assist] the recovery of resilience and adaptive capacity of ecosystems that have been degraded, damaged, or destroyed”. Hence mangrove deforestation decreases biodiversity. ABSTRACT: Daytime sampling using a seine net was conducted at Pak Phanang Bay (Nakhon Si Thammarat Province, Thailand) in February and July 2006, to determine differences in … In addition to the economic problems posed by mangrove deforestation, the report, entitled The Importance of Mangroves: A Call to Action, also cautions that a continued reduction in the surface area of mangrove forests would inevitably expose coastal environments to the harmful effects … 4 Clearing mangrove areas due to natural disturbances such as hurricanes has resulted in introgressions by fast-growing mangrove and nonmangrove species [61–65], and it is likely that selective logging and clear cutting may produce similar outcomes [46]. < Compared to worldwide above-ground biomass data (as a proxy of carbon storage), mangroves in the Atrato River delta represent a significantly high reservoir, but Eastern Coast mangroves lay below the average (Tables 2 and 3; [48, 49]). Conversion of mangrove forests to land for commodity crops has played a significant role in the deforestation of Southeast Asia. In: Leith, H. and Al Masoom, A. 1974.
