8 Hence mangrove deforestation decreases biodiversity. < Mangroves and Salt Marshes 12, Santa Marta, Colombia, 2007. Warner, G.F. 1969. Employing an interdisciplinary approach proved to be useful to demonstrate that basin mangroves are the most threatened physiognomy by deforestation due to their proximity to expanding pastures and villages. 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 . Colombia’s Caribbean Coast harbors 88250 ha of mangroves strongly threatened by human activities [15–18]. 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. An ethnoecological approach has also proven to be useful for understanding the drivers of deforestation [6, 29–32], while ecological economics have helped to account for the costs of mangrove conversion to other uses in a few case studies (e.g., ). Deforestation rates in mangroves are four times greater than those in terrestrial tropical rain forests. 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. = Achetez neuf ou d'occasion Micheli, F., Gherardi, F. and Vannini, M. 1991. Mangrove forests are among the most threatened habitats in the world, and mangrove loss is rampant across the globe. 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”. Invertebrate Zoology. Most of the reliable current knowledge about mangrove change has been obtained by combining coastal land mapping and field surveys in Indopacific locations (e.g., [25–27]). In recent times, mangrove deforestation has raised alarms about increased carbon emissions into the atmosphere. 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 . 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 . Day, J.H. Additional funds came from a Universidad Nacional-DIME grant (code 20101007166) to L. Urrego-Giraldo, and a Universidad de Antioquia-CODI grant (“Mangrove fragmentation in Urabá Gulf”) to E. Estrada and J. Blanco. (eds), Wetlands of Kenya. Deforestation negatively affects benthic communities; however, there are a few accounts on the direct and indirect impacts and mechanisms. Crabs of the mangal ecosystem. 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. 1992. 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. 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. 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. 0 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]. and Dor, I. The influence of crabs on litter processing in high intertidal mangrove forests in tropical Australia. 1991. Mangroves also provide invaluable green economy services for humans.

Conversely, A. aureum was also reported naturally occurring as an understory plant in A. germinans stands in La Mancha (Gulf of Mexico . Finally, basin mangroves were more threatened than fringing mangroves due to their proximity to expanding pastures, villages, and a coastal city. 1 Deforestation: Causes, Effects and Control Strategies Sumit Chakravarty 1, S.

In addition, community and population metrics, otherwise uncorrelated with physicochemical variables under natural conditions , became significantly explained by temperature and pH in deforested mangroves . In: Leith, H. and Al Masoom, A. Mangrove leaders responsible to advance the reforestation work for Fragments of Hope have been monitoring the progress of the reforestation project. . Zonation and distribution of Creek and fringe mangroves in the semi-arid Kenyan coast. The occurrence and distribution of crabs in a Jamaican mangrove swamp. Retrouvez Effects of mangrove deforestation on mangrove mud crab fishery: Ngomeni-Malindi, Kenya et des millions de livres en stock sur Amazon.fr. 2009a). Schrijvers, J. 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. 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 . Jones, D.A. 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.

Annual population growth rate (1993–2005) in this municipality (7.2%) is threefold compared to state- and national-level figures . Uses and sizes for a given mangrove species may differ from one place to another even within a single region in many parts of the world [29, 32]. 1982. 354–377. Extraction of poles from R. mangle trees with DBH < 15 cm has also been reported from Venezuela . Mangroves are a highly threatened ecosystem, as they are converted into other uses such as aquaculture and agriculture. Ruwa, R.K. 1993. In the Urabá Gulf, selective logging has been traditionally conducted by fishermen for direct households and small-scale commerce in Turbo (Figure 4). Similar groups of both epifauna and infauna were recorded in the two areas with differences in distribution along transects in different sampling sessions. What are the effects of deforestation? 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) .
