Bio-geo chemical LSIs may include: Intensive use of space and resources which may lead to poor water and environmental quality related to pollution, noise or species' disturbance; Building new marinas, piers or berths and impact on marine and coastal habitats; Impact on fish stocks Technical LSIs may include: Development helps filter pollutants and . Artificial coral reefs can also be created from ship wreckage that lands at the bottom of the ocean. Erosion is the movement of soil to a new location. For this reason, numerous coastal management strategies have been put in place to preserve these coastlines. coastal use and property values offer an enormous economic investment, Karl Stromberg may have had a vision of a new underwater civilisation in The Spy Who Loved Me, but in reality we havent got particularly far with that. increase mean water depth.

Coastal Resiliency. People touch, stand on and directly damage the reefs. maritime industries. Both methods are expensive and controversial. The threats to coastal communities include extreme natural events such as hurricanes, coastal storms, tsunamis, and landslides, as well as longer-term risks of coastal erosion and sea level rise. Another type of coastal management is hard engineering involves building structures to protect the coast. 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. though these regions are also in high-risk environments, prone to constant The economic losses from the 2005 hurricane season, which included Hurricanes Katrina and Rita, were $200 billion, the costliest season ever. coastal ecosystems. commercial shipping into Poole. They're hotbeds for biodiversity, and are well-worth protecting. DISADVANTAGES 1.

Clearly, such high Coastal areas are not alone in experiencing extreme weather, but living by the sea gives you a front row seat for cyclones, east-coast lows and storm surges. Tourists may also damage reefs by placing objects in the path of flowing water that changes the saltiness of water due to new river flows. Developments are spreading out into the oceans, creating tangles of structures beneath the waters surface. This causes havoc for marine organisms and their habitats, destroying the coral reefs that nourish fisheries and protect the coastline from the harsher impact of the waves, and destablising many precious coastal ecosystems such as salt flats and mangroves. China's efforts to build new land have courted controversy (Credit: Getty Images). Some examples of this is a sea wall,which is a wall set up to prevent the sea eroding an area of land,thishelps prevent flooding,however waves bounce off the wall and scour the beach removing. Even more minor coastal constructions can transform the seas. Seawalls can be made of concrete, rocks or wood. the coast. Scientists often lack the ability to ban tourism from coastal lands, and instead must work to educate tourists, monitor reefs and algae blooms, and create artificial reefs. Land reclamation is big business and today, numerous countries are taking back land from the sea to expand their coastlines and territory. For example, in the Pacific Islands, there are more potentially catastrophic coastal hazards such as tsunamis, flooding, and even droughts. Scientists can monitor reefs and algae blooms to analyze the impact of coastal development and prevent damage. They clear space for larger beaches, build hotels, resorts, airports, marinas, and golf courses. It can reduce the costs of oil-related products for consumers. Coastal development negatively impacts coastal ecosystems by contributing to climate change, increasing ocean acidification, and threatening coral reef ecosystems. Coral reefs are important to human civilization. We also use third-party cookies that help us analyze and understand how you use this website.

Coastal development includes buildings or other structures that are built in order to provide services, such as: Coastal development also refers to natural areas along the coastline that are modified in order to attract or accommodate tourists. You can probably think of many more reasons why coasts need to be protected. Over time, erosion can cause cliff collapse - therefore the coastline needs to be managed. Throughout history, humans have attempted to slow or alter the dynamic coastal zone. draft and enact planning requirements that must meet certain standards. Over time the collapsed land will have much of the smaller debris eroded away and much of the remaining rock or earth will be somewhat smoothed over to create a gentle slope to the water. They are effective in protecting cliffs from erosion They can only absorb the energy of oncoming waves. It is not possible to completely stop the power of natural forces from changing the coast. The high cost of maintenance is arguably one of the biggest disadvantages of living near the sea.
