How can coastal landscapes be viewed as systems?

Coastal Systems Defined

  • Coasts are considered systems because they incorporate a diverse set of components which interact with each other to enable processes and changes.
  • The system can be based on three major concepts: inputs, processes, and outputs.
  • Inputs are the energy and material that are introduced into the system, such as waves, tides, marine organisms, sediments, and humans.
  • Processes are the physical, biological or chemical events or transactions that modify the inputs, such as weathering, erosion, transportation, deposition, and biological activity.
  • Outputs refer to the resultant landforms and materials exported from the system, for example deposited sediment or eroded cliffs.

Open and Closed Coastal Systems

  • Coasts can be classified as either open or closed systems.
  • An open system has both inputs and outputs to and from other systems. Most natural systems, including coasts, are considered open.
  • A closed system has no exchange with other systems. It is self-contained regarding energy and material flow.

Energy Flows in Coastal Systems

  • Energy enters coastal systems in several ways, including: solar radiation, gravity, and tidal energy from the moon. These are important drivers of the processes that shape coastal landscapes.
  • Waves, tides and currents are critical forms of kinetic energy in coastal systems, operating as agents of coastal change.

Material Flows in Coastal Systems

  • Coastal systems also involve significant material flows including fluvial inputs, marine sediment, and weathered material from cliffs.
  • The nature and rate of these material flows can exert significant influence on coastal shape, form and dynamic behaviour.

Feedback Mechanisms

  • Feedback mechanisms can be either positive or negative, serving to amplify or decrease changes within the system respectively.
  • An example of positive feedback would be where the erosion of a cliff base leading to collapse of the cliff face, provides more material to be eroded and further collapsing.
  • An example of negative feedback would be where increased vegetation stabilises a dune system, reducing the potential for wind erosion.

Human Influence on Coastal Systems

  • Humans can be both inputs and outputs of a coastal system.
  • Human inputs can manifest in various forms ranging from physical alteration (like constructing sea defences) to indirect effects through climate change.
  • Human outputs include use of marine resources, tourism, and integration into wider economic systems.

This systematic approach to understanding coastal landscapes provides a useful framework for analysing and predicting changes over time due to natural and anthropogenic influences.

To what extent has intervention in human rights contributed to development?

Understanding Intervention in Human Rights for Development

  • Interventions in human rights involve actions taken by countries, international organisations, and NGOs to promote and enforce rights while addressing human rights abuses.

  • Intervention can take many forms, from sanctions and military intervention in cases of severe human rights abuses, to diplomatic pressure, educational programs and the provision of development aid to stimulate respect for human rights.

  • Development in this context typically refers to socio-economic improvements measured by indicators such as income per capita, literacy rates, access to health services and the overall quality of life.

The Contributions of Intervention in Human Rights to Development

  • Human rights interventions aim to ensure basic rights like the right to life, freedom from torture, freedom of expression, and the right to work are upheld - when these rights are protected, a society can develop more effectively.

  • Interventions promoting rights to education and health contribute to development by improving the overall wellbeing of society and boosting economic productivity.

  • Notably, interventions promoting gender equality play a significant role in development – when women and girls have equal access to rights, health, education, and opportunities, nations witness significant improvements in social and economic outcomes.

  • Peace-building interventions can contribute to development by aiming to resolve conflicts and build strong democratic institutions, which creates a more stable environment for progress.

The Limitations of Intervention in Human Rights to Development

  • At times, intervention could lead to dependency, potentially undermining the development capacity of the recipient country.

  • While well-intended, interventions can sometimes result in unintended consequences - for example, economic sanctions intended to force a change in a country's human rights practices could harm innocent civilians and worsen poverty.

  • Some critics argue that intervention based on Western definitions and understandings of human rights may not be appropriate in all cultural contexts, potentially causing harm to local traditions and societal structures.

  • The effectiveness of intervention is often limited by geopolitical interests, economic considerations and the practical difficulties of enforcement.

  • Some interventions, particularly military ones, could lead to instability or exacerbation of conflicts, further hindering development.

Intervention Success and Accountability

  • The success of interventions depends on several factors, including the scale, methods and duration of intervention, alongside the willingness of local government and society to support and uphold rights.

  • Monitoring and enforcement mechanisms such as the International Criminal Court and the Human Rights Council of the UN seek to hold state and non-state actors accountable for human rights abuses, thereby encouraging adherence to international human rights norms.

  • Many interventions are gradual processes that require long-term commitment, which can pose significant challenges in maintaining momentum and achieving desired outcomes.
