Barbados, December 9, 2024 – When large swathes of invasive seaweed started washing up on Caribbean beaches in 2011, local residents were perplexed.  Soon, mounds of unsightly sargassum, carried by currents from the Sargasso Sea and linked to Climate Change – were carpeting the region’s prized coastlines, repelling some holidaymakers with the pungent stench emitted as it rots.

Precisely how to tackle it was a dilemma of unprecedented proportions for the tiny cluster of tourism-reliant islands with limited resources.

In 2018, Barbados’ Prime Minister, Hon.  Mia Mottley declared the sargassum situation a national emergency.  Now, a pioneering group of Caribbean scientists and environmentalists hope to turn the tide on the problem by transforming the troublesome algae into a lucrative biofuel.

They recently launched one of the world’s first vehicles powered by bio-compressed natural gas.  The innovative fuel source created at the University of the West Indies (UWI) in Barbados also uses wastewater from local rum distilleries, and dung from the island’s indigenous blackbelly sheep which provides the vital anaerobic bacteria.

The team says any car can be converted to run on the gas via a simple and affordable four-hour installation process, using an easily available kit, at a total cost of around $2,500 or £1,940.

Researchers had initially looked into using sugarcane to reduce reliance on costly, imported fossil fuels and help steer the Caribbean towards its ultimate target of zero emissions.

However, despite Barbados being one of few islands still producing sugarcane, the quantity was deemed insufficient for the team’s ambitious goals, explains the project’s founder Dr. Legena Henry.

Dr. Legena Henry grimaces as she points out that while some natural resources are limited, when it comes to the unwelcomed seaweed, she says sargassum is something “we will never run out of”.

“Tourism has suffered a lot from the seaweed; hotels have been spending millions on tackling it.  It’s caused a crisis,” Dr. Henry, a renewable energy expert and UWI lecturer, continues.

The idea that it could have a valuable purpose was suggested by one of her students, Brittney McKenzie, who had observed the volume of trucks being deployed to transport sargassum from Barbados’ beaches.

“We’d just spent three weeks researching sugarcane.  But I looked at Brittney’s face and she was so excited, I could not break her heart,” Dr. Henry recalls.

“We already had rum distillery wastewater, so we decided to put that with sargassum and see what happened.”

Brittney was tasked with collecting seaweed from beaches and setting up small scale bioreactors to conduct preliminary research.”  Within just two weeks we got pretty good results.  It was turning into something even bigger than we initially thought.”

The team filed a patent on their formula and, in 2019, presented their project to potential investors during a side meeting at the UN General Assembly in New York.

Upon touchdown back in Barbados, Dr. Henry’s phone was “buzzing” with messages of congratulations – including one from US non-profit Blue-Chip Foundation offering $100,000 to get the work off the ground.

Biologist Shamika Spencer was hired to experiment with differing amounts of sargassum and wastewater to figure out which combination produced the most biogas.

She says she leapt at the chance to take part.  “Sargassum has been plaguing the region for several years,” Ms. Spencer, who is from Antigua and Barbuda, explains.  “I had always wondered about this new seaweed ruining the beaches in Antigua, and when I came to Barbados to study, I noticed it here too.”

The algae does not just threaten tourism.  They also pose a threat to human health through the hydrogen sulphide they release as they decompose, along with native wildlife like critically endangered sea turtle hatchlings which get trapped in thick mats of beached seaweed.

Water pollution and warming seas are credited with the upsurge in sargassum, another cataclysmic result of climate change that the Caribbean has done little to contribute to but often bears the brunt of.

Calls for eco reparations from leaders including Barbados’ leader Mia Mottley and Antigua’s Prime Minister Gaston Browne have been clamorous in recent years as the region battles ever-rising sea levels and worsening storms.

While waiting for those to bear fruit, this project represents one example of the Caribbean taking its environmental future into its own hands.

This past September, Rum & Sargassum, the Barbados-based start-up founded by Dr. Henry introduced the world to its brand of  RNG, Renewable Natural Gas.  The unveiling featured a vehicle rigged to run on the innovative cocktail of rum distillery wastewater, Blackbelly sheep manure and yes, that no longer pesky but valuable Sargassum seaweed.

Fighting the fungus foe of the beloved banana

How Venezuelan farmers are learning to grow and live with a devastating plant disease

 

In the fields of Venezuela, where the banana has been for generations a symbol of sustenance and tradition, a shadow fell across the land. In 2023, Venezuela’s National Institute of Integral Agricultural Health (INSAI) declared a phytosanitary emergency: the fungus Fusarium Tropical Race 4 (TR4) (Fusarium oxysporum f. sp. cubense tropical race 4; syn. Fusarium odoratissimum) had arrived in producing areas in the states of Aragua, Carabobo and Cojedes.

This fungus, considered a devastating disease of banana and plantain (Musaceae) trees, can remain in the soil for more than two decades, threatening production and the lives of those who depend on it.

In the state of Aragua in the north of the country, the Renacer community had been growing bananas and plantains on 20 hectares since 2018. Then Fusarium arrived.

“When the disease hit, the entire plantation began to deteriorate. We refused to ‘die’ with the trees because that was our livelihood. The visits of INSAI confirmed that we had to chop down the banana trees. I cried a lot because I had worked with my banana trees for years,” recalls woman farmer, Lesbia Margarita García, with a broken voice.

In response, INSAI implemented measures to eliminate the affected plantations and improve the soil health by changing to other crops that allow agricultural production to recover. The Food and Agriculture Organization of the United Nations (FAO) offered assistance by providing corn seeds, tools, biosecurity inputs and training, with teams of experts helping farmers to start again.

“Planting corn, thanks to the INSAI-FAO programme, gave us a harvest that benefited everyone. We have been improving the soil,” says Lesbia Margarita with a smile. “Now we rotate crops, observe soil health and have learned how to use natural fertilizers. Expert assistance has been key.”

The pilot project works directly with affected producers in high-risk areas, promoting alternative crops such as cereals and vegetables, delivering inputs and tools to mitigate damage and applying biosecurity measures for safe and effective containment.

“Beyond the corn received, we have already planted cassava, chili peppers, beans and pumpkin. We hope that by the end of the year [2025] we will be diversified and that each season we will have something to sell. These lands do not give up,” says Lesbia Margarita with conviction.

The Renacer community is beginning to see fruits. Their products are reaching local markets, generating income and rebuilding their livelihoods.

Key actions to manage Fusarium TR4 are ongoing, including regular monitoring, continuous training, inter‑institutional coordination, updates to the national plan, information campaigns and producer impact assessments. INSAI is sustaining regulatory, surveillance measures and training —with FAO support—as part of a comprehensive long‑term strategy.

At the global level, FAO supports awareness raising, capacity building and international collaboration in the fight against Fusarium TR4 by facilitating the World Banana Forum and its Global Network on TR4.

“The objective is for countries to strengthen their operational and technical capacity, articulating actions between the public sector, the private sector and family farmers,” says Raixa Llauger, FAO Agriculture Officer in Mesoamerica. “FAO and local partners have promoted this approach in Venezuela.”

As an essential part of the activities, a comprehensive training programme was developed with activities that taught farmers how to identify the disease contain it and protect crops. In addition, FAO has distributed laboratory equipment, biosecurity tools and a multispectral drone to INSAI. Drones are an efficient and cost‑effective tool for phytosanitary surveillance, offering rapid, high‑resolution monitoring and early detection of plant pests and diseases.

Overall, the project strengthened biosecurity measures against the Fusarium fungus through the adoption of the National Action Plan and the establishment of partnerships with national and international institutions. In addition, the pilot initiative supporting smallholder farmers in key production areas and a nationwide awareness campaign with broad outreach improved surveillance, diagnosis and phytosanitary response capacities across the country.

Widow’s Testimony Recounts Night Haiti President Was Killed

Published

on

MIAMI, Florida — Emotional testimony from Martine Moïse, the widow of assassinated Haitian President Jovenel Moïse, has given jurors in a U.S. federal courtroom a chilling account of the night gunmen stormed the presidential residence and killed the country’s leader.

Martine Moïse took the stand this week in Miami as part of the ongoing trial of several men accused of helping plan and finance the July 7, 2021 assassination, a crime that plunged Haiti into political crisis and remains only partially solved.

She told the court that armed men forced their way into the president’s private home in the hills above Port-au-Prince during the early morning hours, firing multiple shots at her husband while she lay beside him. She testified that she was also wounded in the attack and survived by pretending to be dead until the gunmen left the room.

According to prosecutors, the plot involved a group of foreign mercenaries, including former Colombian soldiers, along with Haitian and Haitian-American suspects. Investigators say some of the men believed the mission was to detain the president, but the operation turned into an assassination.

The Miami trial is focusing on the alleged role of South Florida businessmen and others accused of organizing or financing the plan, part of a wider international investigation that has stretched across several countries.

More than four years after the killing, the question of who ultimately ordered the assassination remains unanswered, with suspects still in custody in both Haiti and the United States as the case continues to unfold.

Jamaica Joins Afreximbank Agreement, Strengthening Africa–Caribbean Partnership

Published

on

CARIBBEAN — Jamaica has become the 13th CARICOM member state to accede to the African Export-Import Bank Establishment Agreement, further strengthening economic ties between Africa and the Caribbean.

The development was confirmed during the 50th CARICOM Heads of Government Meeting, where an Afreximbank delegation led by George Elombi and Kanayo Awani met with Jamaica’s Prime Minister Andrew Holness to advance cooperation.

Prime Minister Holness thanked the bank for its support following Jamaica’s recent hurricane, noting that Afreximbank financing helped restore critical infrastructure including water, electricity, sewage systems and roads, while also assisting reconstruction efforts aimed at building stronger resilience to future disasters.

The meeting also focused on broader development opportunities tied to Jamaica’s membership in the agreement. Discussions included rebuilding and modernising infrastructure such as railways, hospitals and other public facilities, while strengthening regional transportation and trade networks to improve the movement of people and goods across the Caribbean.

Afreximbank has been expanding its presence in the Caribbean as part of its strategy to connect Africa with the region often referred to as “Global Africa.” The bank has already committed billions of dollars in financing and trade support to Caribbean economies in recent years, including funding for infrastructure, trade facilitation and private sector investment.

By joining the agreement, Jamaica gains expanded access to Afreximbank’s financial instruments, technical support and trade networks designed to promote commerce between Africa and CARICOM states.

Regional leaders say the growing partnership could unlock new opportunities in areas such as trade, logistics, tourism, manufacturing and cultural exchange, strengthening economic cooperation between the two regions with deep historical and diaspora ties.
