The operation of the coast as a system

The Coast as a System

Systems Concept

  • The system in geography is used to understand and organise complex interactions and interrelationships.
  • A coastal system is an open system with inputs, processes, outputs and feedback within a distinct boundary, often defined by a watershed.

Inputs, Processes, Outputs

  • Inputs into the coastal system include energy from waves, wind, tides, and ocean currents, sediments from rivers, cliffs, and onshore/offshore transport, and human impact.
  • Processes within the system can be divided into transport processes (longshore drift, traction, saltation, etc.) and erosional or depositional processes (hydraulic action, abrasion, attrition, solution, etc.).
  • Outputs from the system consist primarily of sediment transported offshore or along the coast, changes in coastal morphology due to erosion and deposition, and altered ecosystems.

Feedback Mechanisms

  • A feedback mechanism in coastal systems can be positive or negative, enhancing or constraining changes in the system.
  • Positive feedback amplifies system changes - for example, coastal erosion increases as beach material is removed, allowing waves to attack the base of cliffs more easily.
  • Negative feedback counteracts system changes - for example, a build-up of sediment in coastal waters can reduce wave speed and energy, limiting further erosion or deposition.

Sediment Cell Concept

  • A sediment cell, or littoral cell, is a management tool used to trace the movement of sediments within a particular section of coastline.
  • Sediment cells often have clearly defined boundaries, such as headlands, where the input and output of material roughly equal.

Human Influence

  • Human activity introduces another variable, affecting every aspect of the coastal system, from inputs (adding or subtracting beach material), through processes (construction of sea defences), to outputs (changes in coastal development strategy).
  • Understanding the role of humans in coastal systems is crucial in managing for the future, to minimise risks and maximise opportunities.

Case Studies for Coastal Landscapes

  • Identify specific real-world examples that illustrate these points (e.g., Holderness Coast, UK; Chesapeake Bay, USA). Understand not only the physical aspects of the chosen coastlands, but also socio-economic factors.
  • Use your chosen case studies to deepen your understanding of concepts, and to reinforce the mechanisms within the coastal system.

Causes, consequences, and management of refugee movements

Causes of Refugee Movements

  • Refugee movements are primarily triggered by a fear of persecution due to race, religion, nationality, political opinion, or membership in a particular social group.
  • Accelerated by conflicts and wars, which displace large numbers of people from their homeland. The displacement due to the Syrian Civil War is one of the recent significant examples.
  • Instances of environmental disasters, such as floods, earthquakes or famine, can also lead to refugee movements. This is especially true in cases where the local governance doesn't have the resources or structure to protect or support its population.
  • Social and political instability, including persecution, ethnic cleansing, or oppressive regimes, can force people to become refugees to safeguard their lives and freedom.

Consequences of Refugee Movements

  • The host countries face significant social, economic, and political impacts from refugee movements. There can be strain on employment, public services and infrastructures, often leading to social tension and xenophobia.
  • The displaced people often live in refugee camps with poor conditions lacking basic amenities, posing serious human rights and health care issues.
  • The origin countries can experience demographic changes with potential long-term impacts on their economic development and social structure.
  • Host countries may also benefit from the incoming skills and cultural diversity that refugees can offer, provided there is successful integration.

Management of Refugee Movements

  • The United Nations High Commissioner for Refugees (UNHCR) is responsible for coordinating international action to protect refugees and resolve refugee issues worldwide.
  • Countries implement national policies in managing refugees which can range from offering asylum, providing integration programs to more restrictive measures to deter refugee entry.
  • Politically, there need to be efforts towards conflict resolution in the origin countries to decrease the number of forcibly displaced people.
  • Internationally, the refugee convention and protocols set the legal obligations for the protection of refugees, which aim to ensure their safety and dignity.
  • Non-governmental organisations (NGOs) play a crucial role in providing immediate humanitarian assistance to refugees, such as food, healthcare, and education.
