Scientists create artificial reefs, which preserve biodiversity and provide a place for organisms to seek shelter. Coastal development is especially lucrative when compared to inland development because beaches attract large volumes of tourists. Research finds that spending time by the ocean is pretty good for your wellbeing. Examples of coastal development structures include resorts, dining establishments, and shopping venues. after NorIda, a powerful Noreaster, plowed across the Outer Banks the Office of Ocean and Coastal Resources Management (OCRM) section of the NOAA claims that coastal regions are the number one 2006. Where has beach renourishment been used? Coastal Pressures, Development & Management. Nations consultant Don Hinrichsen estimates in a NOAA paper that 55-60% of Development activities can have significant impacts on the processes and ecological values of coastal areas including beaches, dunes and foreshores. As coasts become more developed, the vulnerability component of the equation increases as there is more value at risk to the hazard. Disadvantages :-Natural Disasters: The coastal areas are very much prone to natural hazards like tsunami, cyclones and floods which results in loss of life, money and infrastructure. The high cost of maintenance is arguably one of the biggest disadvantages of living near the sea. .

Because if you don't protect coastal ecosystems like oyster reefs, marshes, and seagrass beds, then you can lose a lot of the benefits that we derive from the coast, including productive fisheries, outdoor recreational opportunities, erosion control, storm protection, and water quality. These can be classified as (1) energy dissipation through the use of hard structures or (2) supply supplemental sand to eroding beaches through dredging and beach nourishment projects. Employing over 3.2 million people, coastal tourism generates a total of 183 billion in gross value added and representing over one third of the maritime economy of the European Union. beaches.It can also be used to restore wildlife habitats like dune and draft and enact planning requirements that must meet certain standards. Marine biology is the branch of science that studies marine life and human impact on oceanic ecosystems. United But it is Dubai that is home to perhaps the most famous of reclaimed areas. Coastal development causes loss of semi-natural and natural land, destruction and fragmentation of coastal habitats, and is also related to increased erosion levels and increased discharge of diffuse pollution and marine litter to the marine environment. It's all very appealing. Prevents longshore drift moving beach material along the coast. In Cambodia, residents of the Tonle Sap freshwater lake live in floating houses. concrete) that are normally constructed in groups perpendicular to the Beach armoring on the other hand works to maintain the integrity of the Development permits are relatively easy to obtain in many states because seawalls may be built above the high-water mark on private property, and they are relatively inexpensive, compared to beach nourishment.

Corals are usually moved to another place when land is to be reclaimed. Corals are invertebrates that give out calcium carbonate as a waste product, and it's that calcium carbonate that forms the skeleton for the reef. These can be classified as (1) energy dissipation through the use If supply levels increase without an increase in demand, then prices go down for consumers. The current day commercial building of many of the coastal areas around the world will change the natural coastal processes. Because management programs are distributed Costly to build and maintain 3. Their . However, as there are advantages, there are also disadvantages too. cost that is often not factored in original estimates and can range from reducing the level of wave energy reaching the beach will also reduce the The sand is then pulled out to sea where it forms a sand bar.
