Across the Caribbean, governments are demanding that former colonial powers, like the U.K., France and The Netherlands, pay reparations for their involvement in slavery.

Anselm Gibbs, a BBC reporter in Trinidad and Tobago, explains what forms reparations can take and describes the specific demands that Caribbean nations have put forward.

We also hear from Akeem Chandler-Prescod, a member of the Barbados National Task Force on Reparations and his country’s Poet of The Year. He describes how the legacy of slavery still impacts people in Barbados centuries later and how the racial justice movement in the United States has inspired many Bajans to join the reparations movement.

Many European governments have refused to pay reparations. However, some individual families with historic links to slavery have decided to make payments. Laura Trevelyan, a former BBC reporter, explains why her family donated £100,000 ($120,000) to establish a community fund for economic development on the impoverished island of Grenada.

The World Health Organization has warned that mosquito-borne diseases like dengue fever are spreading to new regions. One reason is that warmer temperatures are allowing disease-carrying mosquitos to push into new areas. And wetter monsoons are giving them more time to reproduce in countries like India. According to the WHO, the number of reported cases around the world has jumped from around 500,000 in the year 2000, to 4.2 million in 2022. It’s now found in around 130 countries. So what is dengue fever? And should we be worried about it? The BBC’s global health correspondent Tulip Mazumdar gives us an overview of the symptoms and discusses what treatments are available.
