What is low elevation coastal zone?
The low-elevation coastal zone is defined as the land area and the total and percentage population, by country, that is located in various low elevation coastal zone bands ranging from 1m to 20m elevation above mean sea level.
What is a LECZ?
Low elevation coastal zone (LECZ), or coastal low-lying area, is defined as the contiguous area along the coast that is less than 10 m above the sea level (McGranahan et al. 2007). Overall, the LECZ accounts for around 2 % of the world’s land area.
What is a coastal area zone?
A coastal zone is the interface between the land and water. These zones are important because a majority of the world’s population inhabit such zones. Coastal zones are continually changing because of the dynamic interaction between the oceans and the land.
Why are most of the coastal areas in Africa densely populated?
Africa’s coastal areas tend to be more densely populated due to the economic opportunities there, and populations in these areas are projected to rise at an annual rate of 3.3 percent between 2000-2030, more than double the world average.
What are the characteristics of coastal zones?
Coasts
- Tides. Sea levels rise and fall twice (two times) a day along most coastlines.
- Wave power. Powerful waves hit against rocky coasts, wearing away and breaking off the rocks.
- Cliffs, caves, arches, and stacks.
- Tide pools.

- Deltas.
Why are coastal zones important?
Coastal waters support many fish species and provide breeding habitat for 85 percent of U.S. migratory birds. They also provide habitat for many other organisms such as marine mammals, corals, sea turtles, and submerged aquatic vegetation.
How coastal development affects the ocean environment?
Coastal development may cause the run-off of sediments into coastal habitats, which can smother corals or seaweeds and reduce the amount of light available for photosynthesis. Losses of primary producers and important habitat-forming species such as corals can negatively impact entire food webs.
Why are coastal seas important?

Why is the coastal zone important?
Coastal zones are favoured areas for energy generation because of easy delivery of fuel for power stations and convenient disposal of cooling water. The landward part of the coastal zone plays an important role as a place for human settlement and tourism.
Where is the coastal zone found?
The coastal zone is an interface between the land and sea, which comprised of a continuum of coastal land, intertidal area, aquatic systems including the network of rivers and estuaries, islands, transitional and intertidal areas, salt marshes, wetlands, and beaches (Cicin-Sain and Knecht, 1998).
