Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to . Note, however, that coastal erosion only becomes a problem when there is no room to accommodate change, so coastal erosion is a problem for urbanised frontages but is not for many rural areas where the beach is backed by high ground. In some places coastal erosion is necessary for the preservation of some of the coast’s functions. For example,File Size: KB.
Currently, 40% of soil in Africa is degraded. Degraded soil diminishes food production and leads to soil erosion, which in turn contributes to is particularly worrisome since, according to the UN's Food and Agriculture Organization, some 83% of sub-Saharan African people depend on the land for their livelihood, and food production in Africa will have to increase almost Author: Angela Thompsell. is a moderate risk zone, where physical risks are mostly considered to be due coastal erosion associated with sea-level rise and increased storm activity.

Case studies in Senegal and Benin indicate a strong intensification of coastal erosion, in relation to human influence, as shown by the analysis of Cited by: coastal erosion.
The main causes are the depositing and removal of sediment, which occur via natural processes, such as coastal drift and river discharge. Human activity can exacerbate erosion in multiple ways.
It can affect the removal of sediment, through direct extraction or the creation of surfaces that disrupt the natural processes. Ibe AC, Quelennac RE () Methodology for assessment and control of coastal erosion in West Africa and Central Africa.

The effects of climate change—from changing precipitation patterns to rising seas—will exacerbate the coastal erosion already affecting West Africa, increasing the exposure and vulnerability of the people and assets located there/5.
The purpose of this study is to provide regionally appropriate recommendations to aid the assessment of coastal erosion risk for South West WA. It has been prepared to support application of the design storm approach to coastal hazard assessment following the Western Australian State Planning Policy State Coastal Planning Policy.
Coastal Erosion in West Africa and Adaptation Planning. The West African coast mainly consists of a narrow low-lying coastal strip, over a distance of several thousand kilometers.
This coastal strip is protected from the sea by a sandy barrier. This will lead to the disruption of the coastal barrier if no erosion control measures are taken.

Coastal and Beach Erosion Approximately 40% of South Africa’s population lives within km of the coast and coastal resources are relied on for commercial opportunities as well as for food, recreation and transport, thereby facilitating job creation and general economic upliftment.
Surprisingly, this part of the coastal area in West Lomé experiences the opposite phenomenon to erosion, known as costal accretion, which is the process of sediment accumulation in the coastal zone. We wondered if we could put in place a mechanism of sand transportation from west to east, thus helping the coastal zone east of Lomé begin a.

Ye Yincan et al, in Marine Geo-Hazards in China, Basic Concept of Coastal Erosion. Coastal erosion is a result of human activities and natural environment changes making the coastal dynamic action (wave, current, wind) lose balance in the coastal process, and the long-term loss of sediments of coastal zone results in the destruction process of coastline retreat and beach erosion.The coastal area of West Africa is home to 31% of the West African population and produces 56% of the sub-region’s GDP.
However, today countries are facing increasing risks of coastal erosion, flooding, salinisation of land and coastal waters, as well as depletion of fish stocks- all manifestations that threaten their people and their economic livelihood.has recognized the vulnerability of that coastline to coastal erosion processes, launching the Coastal protection Project in Hazard assessment A wide range of methodologies have been applied for coastal erosion hazard assessment.
The key factors influencing these methodologies include: • The spatial and temporal scale of the analysis.
