Innovative Restoration of Coral Reefs Helps Protect Caribbean Islands

The catastrophic 2017 hurricane season provided ample demonstrations of the increasing vulnerability of Caribbean populations and infrastructure to natural disasters. Researchers at UC Santa Cruz and the Nature Conservancy have now measured the protective role of coral reefs and field-tested a solution that reduces coastal risks by combining innovative engineering with restoration ecology.

Working in Grenville Bay, Grenada, the researchers showed that degradation of coral reefs is directly linked to shoreline erosion and coastal flooding in parts of the bay. The study, published February 1 in the Journal of Environmental Management, also evaluates one of the first uses of reef restoration as natural infrastructure specifically designed to reduce risks to people and property.

Investigating the link between healthy reefs and shoreline stability, the researchers found that Grenville's healthy reefs keep more than half of the bay's coastline intact by reducing the wave energy arriving on shore. In contrast, severe reef degradation is linked with chronic coastal erosion in the northern section of the bay, where the shoreline is disappearing at a rate of nearly two feet every year.

In an attempt to adapt, villagers have built makeshift barriers with tires and driftwood to slow the erosion threatening their homes, but these efforts have been largely unsuccessful. The reef restoration project was designed to enhance both the ecological functions of natural reef habitat and its protective effects.

"We are able to apply coastal engineering tools and models to support reef science and management. Ours is one of the first studies to directly show with evidence from the field sites and engineering models the impacts of reef loss on shorelines," said lead author Borja Reguero, a researcher at the Institute of Marine Sciences at UC Santa Cruz.

The Caribbean Transitional Energy Conference (CTEC)

Caribbean economies suffer from some of the highest electricity prices in the world.

Despite their abundance of renewable energy sources, Cayman has a relatively low level of renewable energy penetration; the economy continues to spend a large proportion of its GDP on imported fossil fuels and residents and businesses continue to pay some of the highest electricity bills in the region. This is a common situation among island nations.

There is a clear opportunity for Cayman to emerge as a regional leader in developing solutions to address climate change through the adoption of renewable energy which will reduce the dependency on fossil fuels and provide key environmental, social and economic benefits.

With the Cayman Islands National Energy Policy now in place, a framework for transition is complete and seizing upon that vision will be critical to affecting positive change for the Cayman Islands and all those who follow.

The recent achievements for islands at COP21 provide a strong driver for action focused on carbon reduction goals. Given that Cayman ranks highly among islands as carbon emitters, it is critical that we position ourselves as leaders in carbon reduction and meet the goals set out in the National Energy Policy and the Paris agreement.

Cayman seeks to stand with other islands in the region and across the world to embrace a low carbon future and to stand on the front line of demonstrating solutions to climate change while delivering cheaper, secure, reliable and economically feasible energy solutions.
Who should attend?

Be part of Cayman’s low carbon future by joining an event which seeks to set out our vision, renewable road-map and opportunities.

The event will bring together delegates from public, private and non-profit sectors, underlining our collaborative approach to a sustainable future- government officials, project developers, manufacturers, investors and key players across the non-profit landscape.

Join government official and industry leads and participate in interactive panel discussions that seek to establish what the journey ahead looks like and how we address the challenges and maximise the opportunities.

Make the most of key networking opportunities, bringing together local, regional and global participation.
