Coasts Present Opportunities And Hazards For People
Overview
Coasts are some of the most crowded places on Earth. People come for trade, fishing, farming, tourism and the sheer pleasure of the sea. But the coast bites back: waves eat away cliffs and beaches, tropical storms drive walls of water inland, and rising seas threaten low-lying land. Living at the edge of the ocean means defending it, or learning when to let it go.
This lesson weighs the opportunities and hazards of the coast and examines how they are managed. You will compare hard and soft (sustainable) engineering, study the distribution, impacts and management of tropical storms, and learn why coral reefs and mangroves matter, what threatens them and how they are protected. Real examples, the eroding US east coast, Typhoon Haiyan and the Great Barrier Reef, ground every idea.
Objectives
- The opportunities of living near the coast.
- The hazards of living near the coast.
- An evaluation of hard and soft engineering strategies and techniques used to manage coastal erosion and flooding; including sustainable.
- The distribution and impacts of tropical storms: cyclones, hurricanes, and typhoons.
- An evaluation of the strategies and techniques used to manage the impacts of tropical storms: preparation, planning, protection, prediction.
- The global distribution, importance of, threats to, and strategies and techniques used to protect and manage coral reefs and mangroves; including sustainable.
- One detailed specific example of a named country or coastal area to include: • the causes and impacts of coastal erosion • the strategies and techniques used to protect the coast from tropical storms and manage erosion; including sustainable.
- One detailed specific example of a named country or coastal area to include: • why the coral reef is important • threats to the coral reef • the strategies and techniques used to protect and manage and the coral reef; including sustainable.
