Conflicts and Resolutions: Reflection

In terms on CZM identifying all paricipants and conflict pressure points. (See below)

Climate change Vs Coastal defence

Dredging Vs Coastal erosion

Designation Vs Comercial fishing

Tourism Vs Bathing Waters

Infrastructure development Vs Run-Off

Agricultural Vs Waste Managment

Habitat conservation Vs legislative powers

Marine Spatial Planning Vs Navigation

The above list of conflicts is summarised from examination below possible strategy and approaches followed by case study summary.

  1. Consider the coastal area as a dynamic natural landscape.
  2. Make only interventions in the coastal processes and in the coastal landscape if the interests of the society are more important than preserving the natural coastal resource.
  3. Appoint special sections of the coast for natural development.
  4. Demolish inexpedient old protection schemes and re-establish the natural coastal landscape where possible.
  5. Minimise the use of coastal protection schemes, give high priority to the quality of the coast resource, and concentrate on shore protection.
  6. Preserve the natural variation in the coastal landscapes.
  7. Restrict new development/housing close to the coastline in the open uninhabited coastal landscape. Allow only such facilities, which require access to the sea.
  8. Maintain and improve the public access to and along the beach, legally as well as in practice.
  9. Reduce pollution and enhance sustainable utilisation of coastal waters.

The factor of strategy to implementation of Marine Spatial Planning was my focus within the exam and the Devon form/Lyme Bay were the main refrerences sources.

Defintion of Marine Spatial Planning

A marine spatial planning system – a planning system for the sea – to enable strategicand integrated plan-led management of sea use at the UK, national, regional and evenlocal levels. Marine spatial planning must be multi-use planning, and the spatial planareas should not be confined to geo-political boundaries, but based on marineecosystems or other meaningful geographical units. A “regional sea” approach, suchas that being tested through the Defra-led Review of Marine Nature Conservation(RMNC) Irish Sea Pilot Study, may be the most appropriate for marine spatial planning,and will require both a UK-wide and national marine policy as well as marinelegislation.

Personal aspirations after year of study:

The chance to be involved in a world changing aspect of science and management is inspiring and through out the year intrest in all areas of this subject have encouraged me to gain my degree at the university of Plymouth with future plans to gain work experience across the globe.

Possible employment:

Coastal Surveyor : Description

We are looking for energetic, scientifically minded, motivated people with good communication skills. You will be working as part of a new team at the forefront of this work in the UK. Your main functions will be to collect, manage, process and analyse coastal data.

Effects of Human Intervention

Although there are many natural causes of coastal erosion, most of the causes affecting coastal communities are due to human intervention in the transport processes along the coastlines and/or reductions in the supply of sand to the shorelines. This article describes how all kind of human interventions may affect coastal erosion.

Coastal structures interfering with the littoral transport are the most common cause of coastal erosion. The presence of the structure has a series of effects:

Trapping of sand on the upstream side of the structure takes sand out of the sediment budget, thus causing shore erosion along adjacent shorelines. Mostly, of course, on the lee side, but large structures may also cause (initial) erosion on the upstream side.

  • Loss of sand to deep water

    Trapping of sand in entrance channels and outer harbours

The structures, which may cause this type of erosion, are:

  • Groynes and similar structures perpendicular to the shore
  • Ports
  • Inlet jetties at tidal inlets and river mouths detached breakwaters

The accumulation and erosion patterns adjacent to coastal structures depend among other things on:


  • The type of coastline , i.e. the wave climate and the orientation of the shoreline
  • The extent of the structure relative to the width of the surf-zone
  • The detailed shape of the coastal structure

Sediment transport processes

The sediment on the seabed is transported when it is exposed to large enough forces, or shear stresses, by the water movements. These movements can be caused by the current or by the wave orbital velocities or a combination of both, the latter being the most important situation. The relevant parameters for the description of the sediment transport along a shoreline or in a coastal area are therefore the following:

  • The wave conditions at the site and the possible variations over the site plus the adjoining areas

  • The current conditions as well as the variations of these over the area

  • The water-level conditions, i.e. tide, storm surge and wave set-up

  • The bathymetry (the depth variations) in the area

  • The sediment characteristics over the area

  • The sources and sinks of sediment, such as rivers, eroding coasts or tidal inlets

Intergrated coastal zone managment

The aim for the introduction of a marine spatial plan is to primarily enhance and sustain bio-diversity with a relation to renewable energy and other marine activities (tourism). The proposal is to produce management for the present and future long and short term. Therefore precise control on legal licence applications and development within the coastal zone. The factor of conflict between activities will play a major role rather that the requiring of licenses from more than one body.

The scope for marine spatial planning is to put in to place a system for the effective management of the marine environment, taking all stakeholders into consideration including the eco-system. Considering this, many areas of exclusion, for specific industries and habitats for species will be competing for recognition ranging from Ministry of Defence testing zones, oil and gas exclusion zones, fishing no take zones, Marine Nature Reserves (MNR’s) for marine species and habitats, Renewable energy exclusion zones, Special Areas of Conservation (SAC’s) for birds, underwater cables, tourism, cultural heritage, undersea mining and many other areas. As many areas of the U.K marine environment vary and an eco-system approach to the bill is being applied and the legislation will differ to suit the needs of the enforced environment and local industry.

Marine Protected Areas

Protected areas:

SACs and SPAs
Special protected areas (SPAs) were formed for the location of maritime migratory birds (SACs) are areas of protection for specified habitats and species of EU relevance

Marine nature reserves (MNR)
formed under the wildlife and countryside act 1981. The purpose to protect geological and physiological features along with conservation of Fauna and flora.

Highly protected marine reserves (HPMRs)
Formed in correlation with (NTZ) where all extractive activities are prohibited.

Voluntary Marine conservation areas (VMCA)

These sites are areas in which local communities protect areas with codes produced to protect a specific area.

The convergence of these protected area schemes through relation of such directives into a marine spatial planning using a streamline of a single body may allow an increase in efficiency to allow more sustainable of conservation to produce a effective answer to the protection of marine bio-diversity.

National Contigency ( Sea Response )

AT SEA RESPONSE

(Counter pollution operations)

All techniques for cleaning up oil pollution at sea have limitations. The distance of the casualty from shore, the type of oil, weather conditions, currents, and the time taken for resources to reach the scene can significantly affect the effectiveness of different techniques. MCA therefore carefully evaluates the circumstances of each incident before mobilising equipment or other resources for Sea Response deployment.
