Mangrove forest cover is a crucial part of the bio-diversity of a locality such as giving a good habitat for a host of marine life. This is proven by the presence of three types of fauna found in mangroves which are resident species (living primarily among the mangroves), the seasonal migrants and the occasional species which visit the mangrove stands once in a while. The scientific study of mangroves and salt marsh as part of the conservation efforts is now a recognized field in engineering and of studies in ecology and oceanography. Mangrove forests are natural ecosystems in many coastal areas around the world and provide a natural coastal defence system which is often overlooked by country planners. Mangroves are a good deterrent against erosion caused by higher sea levels due to global warming and a changed wind pattern from various directions and velocities. Unfortunately, mangroves are under threat today from human activities and expansion.
This paper will discuss how mangroves and salt marsh are crucial components in the coastal defence of areas threatened with erosion from tides and strong winds. It will then also tackle other issues concerning mangrove forests such as clearing them for firewood, charcoal and the other human needs such as for certain coastal developments like resorts. (Crossland & Kremer 47). Humans today are increasingly seen as major catalysts for change among coastal processes which had not been examined very closely before. Human interventions in areas of the coast form part of the larger anthropocene in which larger ecosystems are impacted. Various threats to Mangrove Forests – mangroves are under pressure from us humans especially in developed mangrove areas of the world such as those located along the Niger and delta areas of the Ganges-Brahmaputra and the Irrawaddy in Burma (Kathiresan 476). Other threats identified are degradation and destruction of the mangroves, plant disease and global warming from climate changes. Some 90% of identified global mangroves are located in developing countries which make these mangrove forests particularly vulnerable to human exploitation and expansion of human activities. The estimated 18 million kms2 of mangroves in 1997 has since been reduced to a mere 15 million square-kilometres; it takes a long time for mangrove forests to recover once these are destroyed. Human Encroachments – this is perhaps the greatest threat to mangroves due to the various activities of humans such as urbanization (like in Singapore), Bangkok, Rangoon and in India (Calcutta and Bombay). Another is agricultural expansion from reclamation activities and for aquaculture purposes such as building ponds for shrimps. Other reasons are cutting the mangroves for firewood, charcoal and lumber (mangrove timber is highly resistant to the usual deterioration of wood because of high phenol content). The mangrove areas are usually drained of their salt water content using rain water and protected from salt water intrusions. Degradation – this results when the health and productivity of the mangrove areas had deteriorated significantly from various causes. Among identified causes are oil pollution, dumped ...Download file to see next pagesRead More

The role of salt marshes in the coastal system

...? Role of Salt Marshes By of Due Introduction: Antoine Lavoisier once said, “Vegetation is the basic instrument the creator uses to set all of nature in motion.” It is this vegetation that provides us with much of the oxygen we breathe everyday and the pleasant environment we live in. Salt Marshes are areas where a lot of rich vegetation thrives. These areas form the junction between ocean water and fresh water. These areas are frequently seen along the coastal belts and are rich in salty water. Consequently the plants that thrive here are salt tolerant plants. Since salt marshes are shallow areas, the plants that exist in salt marshes are those that can adapt to the tidal changes in the volume of water. The water waves that make... it to...

Life and Death of the Salt Marsh

...Environmental Studies Topic: of the environment: Environmental Controversies Life and Death of the Salt Marsh Introduction: Defined as wetlands that are always flooded, with characteristic plants that have soft stem, according to (US Environmental Protection Agency: EPA), marshes are of different types. There are those marshes existing in fresh waters and those existing in salty waters. Some are found inland while others are found on the coastal lines. They can also be categorized as either prairie or everglades. They are supplied with either surface or ground waters, having many nutrients that create a suitable environment for animals and plants to...

Coastal Defence

...claimed land from reinundation by the sea, it is also a requirement of land claim to install some form of flood defence. (Doody 275-283) This defence is largely to keep the sea out, rather than an anti-erosion structure, and so tends to be more a flood defence measure than a measure for coastal protection. Typically this defence is an earth embankment, sometimes faced with stone, although occasionally defences may be concrete walls, particularly in cases of. high hinterland value, such as land claim for industrial development, nuclear power stations, or port activity. These flood defences are often constructed using...

Salt-water Invasion in Coastal Wells

...It is vital to for the government to continue administering lots of efforts in the prevention of salt-water invasion within the coastal wells since these regions are not only economically suitable, but also environmentally vibrant. The United States’ coastal regions support more than half of the Nation’s population and host a diverse ecosystem. Furthermore, they are home to the fast growing counties, depicting a continuous growth within the coastal areas in the future. Truthfully, populations within the coast and industries need a host of natural resources in order to sustain their existence. Most importantly, they require a reliable source of freshwater for drinking and...

Coastal engineering

...Coastal Engineering Introduction: The Ocean waves are formed by interactions of   the moon, sun, and earth. The moon and earth are like magnets thatattract. When the moon pulls on the Earth, the earth cant hold on to the water because it is always moving, so the moons gravity pulls on the ocean tugging at the water causing it to sway and move thus this tugging and saying causes the surface to take on the form of a wave. The communities and industries along the coastal zone heavily rely on this zone. Engineers are working very hard to make sure these communities and the industries survive the strong effect of the forces of the nature provided by the waves and the tides. This has brought about constant developments and maintenance... of the...

The Hurricane Sandy that hit the U.S. coastline on October 2012 caused massive destruction to properties on the coastline and left hundreds of people dead (Foster, 2014). Official report released after the disaster confirmed that at least 117 American citizens perished in the disaster while 69 others died in Canadian and Caribbean coastline making the hurricane the deadliest and most destructive hurricane disasters ever. However, evidences point that the destruction caused by the hurricane could have been minimized if proper measures were put by homeowners and contractures...

Salt Marshes

.... The importance of the salt marshes is to protect the coastal regions from storms, to provide habitat for birds and animals, to reduce the degree of pollutants entering the ocean water and to provide a good environment for the mangroves to grow (Bailey and Facts on File 103). Scientists have conducted an intense search on the salty marshes, and they have come up with reasons to support the excessive nitrogen release from the land. Climate change has contributed to the factor of the land, releasing too much nutrient because of the extreme weather situations (Charton and Facts on File 276). Additionally, the nutrients usually originate from sewage,...
