effects of mangrove deforestation

Conversion of mangrove forests to land for commodity crops has played a significant role in the deforestation of Southeast Asia. Mangroves and Salt Marshes 2, 75–83 (1998). J. F.

Finally, basin mangroves were more threatened than fringing mangroves due to their proximity to expanding pastures, villages, and a coastal city. 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]). 1984. The oil spill in Guimaras caused 0.932 ha mangrove deforestation three months after the incident, which was distributed to four patches in the municipality of Nueva Valencia (Sadaba et al. Climate change also affects their survival. Feeding and burrowing ecology of two East African mangrove crabs. Mangrove conservation must consider diverse socio-economic, cultural and political challenges that vary across regions and nations (Friess et al., 2016). [. Above-ground biomass for mangrove forests worldwide. 89–109. Mangrove leaders responsible to advance the reforestation work for Fragments of Hope have been monitoring the progress of the reforestation project. Box 81651, Mombasa, Kenya, Kenya Wildlife Service, P.O. For this reason, coastal plain native forests (5048 ha including mangroves) have been decimated and replaced by urban (1499 ha), agriculture (67802 ha), and pasture (142385 ha) [43]. Vanhove, S. and Vincx, M. 1990. 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. 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]. In other areas such as Punta Yarumal where mangrove trees have been selectively logged, A. aureum formed clumps in the understory. The objective of this paper was to answer the following questions. Deforestation negatively affects benthic communities; however, there are a few accounts on the direct and indirect impacts and mechanisms. At a landscape scale, we also reported that both selective logging and mangrove reclamation were responsible for reduced density in N. virginea (as well as in Melampus coffeus-Ellobiidae, a typical mangrove pulmonate gastropod) in Punta Yarumal in the vicinity of Turbo [40].

Moreover, the codominance of secondary mangrove species or antagonistic distributions can be indicators of cryptic ecological degradation (Dahdouh-Guebas et al. (eds), Towards the Rational Use of High Salinity Tolerant Plants. The ‘borders’ that demarcate human settlements with newly-destroyed forest are actually attractive to animal life. In the surroundings of Turbo City (Punta Las Vacas), the mangrove fern Acrostichum aureum also invaded extensively cleared fringing mangroves (Figure 4(l)), and it has become a major barrier for natural recovery, as observed elsewhere [8, 25, 46, 67]. Schrijvers, J. 1996. Princeton U.P. Moreover, healthy mangroves act as a buffer, protecting coastal areas from the effects of floods and tsunamis, thus contributing to coastal communities’ ability to adapt as the frequency and severity of such events increases due to climate change. Mangroves also provide invaluable green economy services for humans. Bogotá D.C., Colombia, 1997. 1991. Mapping this change has been, however, elusive despite the publication of mangrove cover and conservation status maps by the National Mangrove Inventory Project during the nineties [17, 18] and the fine-scale efforts conducted by state-level environmental boards afterwards [21]. Selective logging seems to reduce total mangrove biomass and carbon, particularly in basin mangroves, but more importantly it is clearly altering allocation among species by reducing the storage in R. mangle and A. germinans and increasing the L. racemosa reservoir. Amazon.com: Effects of mangrove deforestation on mangrove mud crab fishery: Ngomeni-Malindi, Kenya (9783659177378): Fondo, Esther, Kimani, Edward, Odongo, Dixon: Books Mangrove restoration is the regeneration of mangrove forest ecosystems in areas where they have previously existed. 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”. However, as stated by Bouillon et al. 78: 191–198. Kitheka, J.U., Ohowa, B.O., Mwashote, B.M., Shimbira, W.S., Mwaluma, J.M. Extraction of poles from R. mangle trees with DBH < 15 cm has also been reported from Venezuela [53].

A. germinans formed nearly monospecific stands in the interior (basin) of the Eastern Coast mangroves. This forest also exhibited the lowest mean tree diameter and mean density (Table 1), a pattern promoted by selective logging of R. mangle and A. germinans, the species with greater importance value (IVI) in the Eastern Coast (Figure 3). Flow diagram, summarising the main factors responsible for mangrove deforestation in the Lower Volta, together with the principal ecological and socio-economic consequences (after Qureshi, 1996). Quantification of deforestation rates and land cover and land use transitions has been impeded by the lack of robust mangrove cover maps. 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. The influence of crabs on litter processing in high intertidal mangrove forests in tropical Australia. 1974. Box 82144, Mombasa, Kenya, You can also search for this author in Selective logging promoted canopy gaps, alteration of forest structure, and sediment trampling, while mangrove conversion to pastures promoted increased soil temperature and desiccation and eliminated hard substrates (trees, prop roots, seedlings, and pneumatophores) (Figure 4, Figures 6(a), and 6(d)). 1988. 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. Mombasa, Kenya. Dr W. Junk Publishers. This study documents comparative variations of macrofaunal densities in a deforested area and a natural mangrove area in Gazi Bay, Kenya, during 1993. 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. Mangroves dominate tropical coasts and provide important services to humans, yet they are one of the most threatened ecosystems partially due to deforestation [1–3]. 1984. Bogotá D.C., Colombia, 1998. In addition, extraction of woody and nonwoody products has degraded many mangrove areas thus translating in low stature and slim diameter development [19–21]. Oecologia. pp. 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]). Macintosh, D.J. Colombia, located in the northernmost corner of South America, with coasts in both the Caribbean and the Pacific, exhibits the largest annual deforestation rate out of the eight South American countries with mangroves [13]. 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]. A total of 53 REM mangroves were established as part of the initial training and follow-up activities. Selective logging may indirectly affect climbing gastropods (i.e., L. angulifera and M. coffeus) by eliminating their preferred habitats because they crawl on the trees during flooding tides [40, 77]. 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. 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 ( In: Kenya Belgium Project, 4th Quarterly Report. Changes in patterns of macrofaunal distribution in mangrove ecosystems at the Kenyan coast due to natural and un-natural causes. pp. H. Sánchez-Páez, G. A. Ulloa-Delgado, and R. Álvarez-León, Eds., “Hacia la recuperación de los manglares del Caribe de Colombia,” Proyecto PD 171/91 Rev.2 (F) Fase II, Etapa II. A. germinans trees are not commonly marketed, but they are logged on demand for construction pilings and planks (Figure 4). The future of mangroves very much depends on us and in fact our future is co dependent on the survival of these critical habitats. A. Etter and W. Van Wyngaarden, “Patterns of landscape transformation in Colombia, with emphasis in the Andean region,”, L. López-Hoffman, I. E. Monroe, E. Narváez, M. Martínez-Ramos, and D. D. Ackerly, “Sustainability of mangrove harvesting: how do harvesters' perceptions differ from ecological analysis?”, F. Dahdouh-Guebas, I. By 2003, it was estimated that 6993 ha of mangroves existed in the Urabá Gulf using satellite images [17, 42]. J. F. Blanco, M. Londoño-Mesa, and L. Quan-Young, “The Urabá Gulf mangrove expedition of Colombia,”, M. Coll, A. C. Fonseca, and J. Cortés, “El manglar y otras asociaciones vegetales de la laguna de Gandoca, Limón, Costa Rica,”, H. M. Guzmán, P. A. G. Barnes, C. E. Lovelock, and I. C. Feller, “A site description of the CARICOMP mangrove, seagrass and coral reef sites in Bocas del Toro, Panama,”, L. E. Urrego, E. C. Molina, J. In addition, different mangrove types (e.g., riverine, fringing, basin) provide specific services and support coastal fisheries to a different extent [6, 7], but they may also provide differential carbon capture capabilities [8–11]. Micheli, F., Gherardi, F. and Vannini, M. 1991. 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]. 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]. In addition, community and population metrics, otherwise uncorrelated with physicochemical variables under natural conditions [84], became significantly explained by temperature and pH in deforested mangroves [86]. As a case study, we used the Urabá Gulf (Colombian Caribbean), an ecologically important yet threatened ecoregion located in the northern part of the Biogeographic Chocó biodiversity hotspot [35, 36]. Mangrove forests in the region were lost at an average rate of 0.18% per year. This region remained poorly explored by ecologists during most of the 20th century due to public order issues, and mangrove forest inventories were limited to specific areas of interest [35]. Accurate estimates of global deforestation rates of mangroves are not available; its well-known environmental and socioeconomic impacts are observed and increasingly documented in coastal communities that depend directly on mangroves, and in upland … 0 This is a preview of subscription content, log into check access. These mangroves have been converted to agricultural lands, shrimp aquaculture ponds, and urban development (mostly for tourism). In: Wildlife Clubs of Kenya. 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. Flow diagram, summarising the main factors responsible for mangrove deforestation in the Lower Volta, together with the principal ecological and socio-economic consequences (after Qureshi, 1996). 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]. Fondo, E.N. Kitheka, J.U. 1 Such reductions seemed to be primarily mediated by changes in surface sediment properties (e.g., pH, temperature, organic matter content) and microhabitat complexity (trees, prop roots, and pneumatophores). 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]. Study of the meiobenthos in five mangrove vegetation types in Gazi Bay, Kenya. In the Urabá Gulf, selective logging has been traditionally conducted by fishermen for direct households and small-scale commerce in Turbo (Figure 4).

Annual population growth rate (1993–2005) in this municipality (7.2%) is threefold compared to state- and national-level figures [43]. Effects of mangrove deforestation on fish assemblage at Pak Phanang Bay, southern Thailand. Mangroves offer provisioning, regulating, supporting, and cultural services [4–6]. Regardless of the mangrove location, R. mangle contributed most of the carbon reservoir but in the suburban basin mangroves L. racemosa contributed a similar amount (Table 2). Journal of Animal Ecology 38: 379–389. Deforestation and hydrological changes are the most devastating to soil nutrient-plant relations and mangrove productivity. 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]. The report recommends several measures to conserve and restore mangroves. 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]). Mangroves are a highly threatened ecosystem, as they are converted into other uses such as aquaculture and agriculture. Internal Report. 1974. 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 … 0 Ruwa, R.K. 1988. Crabs of the mangal ecosystem. Limnology and Oceanography 41 (1): 169–176. 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. 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]. PD 171/91 Rev.2 (F) Fase I. Conservación y Manejo Para el Uso Múltiple de los Manglares de Colombia, MinAmbiente/OIMT. Continued deforestation of mangrove areas disturbs habitats and damages biodiversity, a key effect of this being the decline in fishery yields. The basin mangrove physiognomy and the dominant species (A. germinans) are also threatened, because, in contrast to the rest of the Caribbean, only small patches exist naturally at the Eastern Coast of the Urabá Gulf. Indiscriminate felling of trees in the greater parts of Dhaka, Mymensingh, Rajshahi, Rangpur, and Dinajpur has resulted in an alarming depleting of the forests. 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]. https://doi.org/10.1023/A:1009982900931, DOI: https://doi.org/10.1023/A:1009982900931, Over 10 million scientific documents at your fingertips, Not logged in and H. Thiel (eds). MSc. Observed above-ground carbon reservoirs in the Urabá Gulf are within the range observed in the Tropics [10, 11, 49, 56, 57]. 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. Therefore, selective logging seems to unbalance carbon allocation among species rather than promoting a net loss in total reservoir. This study quantifies the proximate drivers (i.e., replacement land uses) of mangrove deforestation across Southeast Asia between 2000 and 2012. Deforestation negatively affects benthic communities; however, there are a few accounts on the direct and indirect impacts and mechanisms. . Gastropods in the Caribbean and elsewhere have been pointed as key detritivores and sediment grazers, even outweighing the role of crabs [80–82]. Marine Biology 111: 247–254. PubMed Google Scholar, Fondo, E., Martens, E. Effects of mangrove deforestation on macrofaunal densities, Gazi Bay, Kenya. Journal of Animal Ecology 43: 51–69. B. Kauffman, D. Murdiyarso, S. Kurnianto, M. Stidham, and M. Kanninen, “Mangroves among the most carbon-rich forests in the tropics,”, N. C. Duke, J.-O. Colombia’s Caribbean Coast harbors 88250 ha of mangroves strongly threatened by human activities [15–18]. Therefore, it is important to understand the objectives of selective logging to explain patterns in terms of sizes exploited, level of exploitation, degree of mechanization, and spatial distribution as influenced by access from towns and villages [6, 25, 32]. 8 Finally, selective logging might be responsible for local extinction of the vulnerable mangrove species Pelliciera rhizophorae (Figure 3: Puerto Cesar-Punta Coquito and Atrato River Delta; but recently recorded in Punta Las Vacas). Deforestation rates in mangroves are four times greater than those in terrestrial tropical rain forests. Anthropogenic development reduces the island's mangrove forests, threatening the health of surrounding coral reefs. Deforestation of mangroves is occurring at an alarming pace of approximately 150,000 ha per year. 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). Effects Of Mangrove Destruction In Mumbai Environmental Sciences Essay. In recent years, mangrove deforestation has raised alarms about increased carbon emissions into the atmosphere. 1992. Computed from structure data from Urrego et al. Journal of Ecology 50: 19–34. Research on Rhizophera stylosa and Avicennia marina in Australia has shown that severe mangrove deforestation from oil spills can take around 36 years to recover fully, with 50 percent recovery after 20 years (Duke et al, 1998). Finally, selective logging and mangrove conversion to pastures were responsible for density declines of dominant gastropods (N. virginea) in mangrove canopy gaps and edges, and it is hypothesized that cascading effects may consequently occur in sediment bioturbation and leaflitter processing. The IUCN Wetlands Programme. 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. Along this coast, entire basin mangroves have been converted to pastures, thus locally decimating mangrove patches along with the dominant A. germinans (Figures 4(i) and 4(j)), similarly to the reported patch shrinking and species extinctions in periurban mangroves in Mombasa (Kenya) [47]. In addition, increased erosion due to land deforestation can massively increase the amount of sediment in rivers. In: Crafter, S.A., Njuguna, S.G. and Howard, G.W. [46]).

Effects of mangrove deforestation on mangrove mud crab fishery: Ngomeni-Malindi, Kenya by Esther Fondo (2012-07-23): Books - Amazon.ca Area and structure parameters (mean values) for mangroves in the Urabá Gulf. 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. A guide to marine life of south African shores. 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. Conversion of mangrove forests to land for commodity crops has played a significant role in the deforestation of Southeast Asia. 0 Funding was provided by the Antioquia State Planning Secretariat, Universidad de Antioquia, Universidad Nacional and EAFIT consortium named “Expedición Estuarina, golfo de Urabá, Fase 1”. The mangroves of the Eastern African region. Coastal Wetland Utilization. Freshwater diversions can also lead to mangroves drying out. 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]). These include creating a global mangrove fund, … J. F. Blanco, E. A. Estrada, L. F. Ortiz, L. E.

Álvarez-León, O. 736 pp. Anthropogenic development reduces the island's mangrove forests, threatening the health of surrounding coral reefs. In addition to selective logging, clear cutting of basin-type mangroves is a common practice for establishing pastures, thus extracting most of tree biomass and leaving a few standing A. germinans trees. Journal of Sea Research 35(4): 257–268. In general, mangroves have specialised root structures (breathing roots or pneumatophores) as a result from their physical adaptation to oxygen-poor or anaerobic sediments/soils. Symposium of the Zoological Society of London. Authors; Authors and affiliations; Tatsuya Shinnaka; Mitsuhiko Sano; Kou Ikejima; Prasert Tongnunui ; Masahiro Horinouchi; Hisashi Kurokura; Article. ELICE contribution No. We are committed to sharing findings related to COVID-19 as quickly as possible. It is in contrast with the observed in some areas of Mexico, where L. racemosa is preferably exploited for woody products over A. germinans and R. mangle, species that are mostly used for nonwoody products (i.e., medicine and leather dying), while no wood is burned for charcoal production [29]. 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. In the Caribbean region, mangroves have been cleared at a rate of ≈1% yr−1, but figures are greater in mainland than in insular sites (≈1.7 and 0.2% yr−1, resp. Selective logging and mangrove reclamation indirectly increased the IVI of L. racemosa in suburban basin mangroves (see discussion in Section 5), in contrast to the observed in isolated mangroves (Figure 3).
