Coastal Environments Are Of Great Importance To People And Need To Be Sustainably Managed
Gbogbo ọrọ náà
Coastlines are among the most contested spaces on Earth. They attract tourists, provide livelihoods for fishing communities, support unique ecosystems, and house millions of people, yet they are constantly reshaped by waves, tides and storms. When the sea threatens to flood or erode, decisions about how to respond pit conservation against development and short-term cost against long-term sustainability.
In this lesson you will learn how conflicts arise between different coastal users, why coastal flooding occurs, and how it can be predicted and prevented. You will compare hard and soft engineering strategies, evaluate their costs and benefits, and study real-world case studies from both a developed and a developing or emerging country.
Ebumnobi
- Conflicts between different users of the coast, with different views on coastal management (conservation or development)
- Causes of coastal flooding (storm surges, tsunamis, climate change) and the prediction and prevention of flooding (forecasting, building design, planning and education)
- There are different coastal management strategies, including soft engineering (beach replenishment, cliff regrading, ecosystem rehabilitation and revegetation, managed retreat), hard engineering (groynes, revetments, sea walls, gabions, riprap) and shoreline management plans
- Case studies of coastal management in a developed country and a developing country or an emerging country
