Prince Harry will visit a Grenadan beach today to learn about the impact climate change is having on the Caribbean's environment.
On one of the island state's most beautiful beaches, Harry will be told about the steps organisations and institutions are taking to repair and protect the country's precious eco-system.
The Prince will learn how gardeners from the Coral Restoration Project are rebuilding the coral reef and encouraging plants and coral to flourish in Grenada's waters again.
And he will see how the nation is restoring its mangrove habitats, an important part of the country's eco-system, which were extensively damaged by Hurricane Ivan in 2004.
Harry was due to travel to Grenada on Royal Fleet Auxiliary Wave Knight, a tanker on anti-narcotics and disaster relief duties in the region, but it developed a technical problem on Sunday which meant it could not leave its St Vincent mooring on schedule.
There was no update overnight from Kensington Palace about the situation so it is not known if the vessel was able to sail or if other arrangements - most likely chartering a plane - were put in place.
A Kensington Palace spokesman said on Sunday: "Contingency plans are in place and there is no current expectation that the second half of the tour will be impacted by the technical problem with Wave Knight. We are looking forward to meeting the people of Grenada tomorrow.''
Harry is midway through a 15-day tour of the West Indies that has already taken him to Antigua and Barbuda, St Kitts and Nevis, St Lucia and St Vincent and the Grenadines.
