Coastal management and sustainability

Coastal Management and Sustainability

Introduction

  • Coastal environments are dynamic and sometimes highly unstable, subject to both slow and rapid changes.
  • Human activity in coastal areas, such as development and tourism, often altered these natural processes.
  • Coastal management aims to protect homes and infrastructure from the threat of coastal processes such as erosion and flooding.

Sustainable Management of the Coast

  • Sustainability refers to practices and approaches that meet the needs of current generations without compromising the needs of future generations.
  • Sustainable coastal management involves a balanced approach, ensuring social and economic growth while preserving the coastal environment and flora & fauna.

Approaches to Coastal Management and Sustainability

  • Soft engineering solutions, such as beach nourishment and dune stabilisation, tend to be more sustainable, working with natural processes rather than against them.
  • Hard engineering techniques, such as sea walls and groynes, can provide immediate protection but can cause changes to the natural coastal processes, often leading to more problems elsewhere.
  • Integrated Coastal Zone Management (ICZM) refers to the management of the coastal zone for the benefit of all, balancing conflicting demands and protecting natural systems.
  • Strategic Retreat is considered as a long-term and sustainable solution. Involving moving people and infrastructure away from areas at risk, restoring natural defences such as marshland.
  • Adaptive management is a systematic approach for improving coastal management by learning from the outcomes of previous strategies.

Case Examples

  • In the UK, coastal management strategies are often informed by Shoreline Management Plans (SMPs), which look at the predicted changes to the coastline over the next 100 years.
  • The Holderness Coast (East Yorkshire, UK) provides an example of both hard and soft management techniques.

Benefits and Challenges of Sustainable Coastal Management

  • Sustainable management can lead to long-term economic benefits through tourism and increased biodiversity.
  • It involves the local community, leading to better understanding and support of the management plans.
  • However, achieving sustainability may involve limiting development and might face resistance from stakeholders.
  • Sustainable strategies, such as managed retreat, could entail resettlement of communities or loss of land.

Conclusion

  • Sustainable management of coasts is increasingly important due to the threat of climate change.
  • Sea level rise and increased storminess will exacerbate coastal erosion and flooding.
  • The focus on sustainability will help ensure that the valuable resources of our coastal areas are preserved for future generations.
