Climate change adaptation and hurricane disaster resilience in the UK Overseas Territories

Climate change is one of the leading threats to global biodiversity and yet biodiversity underpins our resilience to natural hazards. The highly diverse and vulnerable natural environment of the Caribbean and Western Atlantic Overseas Territories is critical for providing resilience against tropical storms which are increasing in severity as a result of climate change.

The JNCC-led Climate change adaptation and hurricane disaster resilience project highlights the need to protect key habitats across the participating Overseas Territories in the context of storm-induced flooding. The project aims to demonstrate the function, role, and economic value of the natural environment in mitigating damage caused by tropical storms and to embed nature-based solutions into policy-making. This work is funded with UK aid from the UK government through the Conflict, Stability and Security Fund (CSSF).

Introduction

Vibrant coral reefs, dynamic mangrove lagoons, and expansive inland vegetation are some of the key habitats that comprise the Caribbean and Western Atlantic Overseas Territories. Island nations are highly aware of the value that their unique environment brings to local communities as nature is often entwined into the activities of daily life. Coastal habitats provide nurseries for an array of fish and coral species which support the wider coastal-marine ecosystem and underpin local food security, tourism, and fishing industries.

Diverse and thriving coastal habitats also have a vital role in protecting against the destructive power of tropical storms. Extreme winds, inland flooding from high rainfall, and coastal flooding from storm driven waves can cause devastating damage to coastal areas and communities. Inland vegetation improves rainwater drainage, reducing surface water flows associated with flood risk. While coastal vegetation, such as mangroves and near-shore coral reefs, lessen the height and destructive power of incoming waves and reduce the risk of flooding to coastal areas. The resilience of many Caribbean Overseas Territories to storm-induced flooding is dependent on the health and abundance of these key habitats.

Nearly 80% of the population of the UK Overseas Territories live in the hurricane-prone Caribbean and Western Atlantic region where tropical storms pose a serious risk to human life, livelihoods, and infrastructure. Due to the effects of climate change, tropical storms are becoming more severe and heightening the risk of damages to coastal communities. Damage to livelihoods, property, and economic and natural assets seriously impedes opportunities for economic growth and prosperity for affected countries.

Effective management measures across all sectors of society are needed to conserve key habitats and ensure that their protective role is retained to reduce further risk to human life and livelihoods. The Climate change adaptation and hurricane disaster resilience project aims to raise awareness of the growing risk of flooding associated with climate change, demonstrate the role and value of the environment in mitigating this risk, and provide the technical capacity to embed nature-based solutions into policy-making.

JNCC is working in partnership with the governments of the British Virgin Islands, Cayman Islands, Montserrat, and the Turks and Caicos Islands, to identify areas and communities at risk of flooding, and opportunities to utilise the protective capacity of nature to reduce the threat that storms pose. Protecting and enhancing the resilience of the environment against natural hazards will drastically reduce the economic burden placed on the Overseas Territories and support future sustainable development.

Objectives

The objectives of the project are to:

  • Assess the functional role and the monetary value of natural capital in participating Overseas Territories for protecting livelihoods and infrastructure from natural hazards.
  • Identify and map opportunities for nature-based solutions to mitigate the impacts of flooding and increase environmental resilience.
  • Develop a framework of natural capital indicators to monitor environmental change in the context of disaster resilience.
  • Share knowledge and build capacity among local communities and national agencies to undertake future assessments and support ongoing disaster resilience.

The project supports the UK Governments’ National Security Council (NSC) Strategy to assist in the development of robust disaster preparedness across all Overseas Territories, identifying and mitigating the impact of climate change.

Outputs

The project outputs will include:

  • GIS-based storm-surge and inland flooding models to identify communities and areas at risk and opportunities for nature-based solutions.
  • An environmental indicator framework to enable the monitoring of environmental response to natural hazards.
  • Stakeholder engagement and training events to convey the key messages around the importance of the natural environment.
  • An economic assessment of the monetary value of key habitats in supporting the natural environment.

Details of published outputs will be provided when available.

The project builds upon the Natural Capital in the Caribbean and South Atlantic Overseas Territories: Valuation, Vulnerability and Monitoring Change programme undertaken between 2016 and 2019.
