GLOBAL – Mangroves are havens for biodiversity, and living dikes that help shield against storms and waves that are growing ever stronger in a warming climate. And yet, they remain one of the world’s most threatened tropical ecosystems; we’ve lost over 35% of the world’s total in two recent decades, largely due to clearing of mangroves for aquaculture, agriculture, urban development and timber. That’s why there’s rising interest from governments, nonprofits and local communities around the world in rebuilding these vital systems. But such endeavors often fail. In the Philippines, for instance, less than 20% of planted saplings survive, on average, while a large-scale study estimated a median survival rate of roughly 50%. Now University of Ruhuna botanist Sunanda Kodikara and other scientists are increasingly urging organizers to abandon old approaches to regrowing mangroves and the misdirected incentives that drive them. Instead, they argue for a science-based approach that takes into account the forests’ sensitive ecology and tendency to regenerate naturally, and the needs of people who live around them. As coastal and marine ecologist Catherine Lovelock of the University of Queensland in Australia notes, “We all understand exactly how you grow a mangrove forest, and it’s been known for quite some time.” The problem, she says, has much more to do with people than with science.AFRICA Pastoralist women unbowed despite suffering wrought by climate crisis Niger Delta mangroves in ‘grave danger’ from oil spills, poverty, invasive species NIGERIA – Nigeria reportedly has 206 trillion cubic feet of natural gas reserves, and the world’s 10th-largest reserve of crude oil, amounting to around 25 billion barrels. Oil contributed 7.24% of Nigeria’s GDP in 2021, and oil exports continues to dominate the country’s foreign exchange earnings. Growing evidence, however, suggests that the pursuit of oil is at the heart of irreversible ecosystem damage affecting people and mangroves alike. In the past decade alone, there were more than 8,636 oil spill incidents, which released a combined 385,909 barrels of oil into the surrounding environment, according to data from Nigeria’s National Oil Spill Detection and Response Agency (NOSDRA). The ongoing spills, regulatory agencies say, are a result of leaks from old and unserviced pipelines, as well as artisanal oil refining operations. Significant leaks also come from oil “bunkering,” a form of oil theft in which pipelines are punctured and oil illicitly diverted to unauthorized destinations. This diverted crude, known as “dirty fuel,” is refined and sold in Nigeria’s booming black market. “The mangrove forests of the Niger Delta are among the most degraded in the world,” said Nenibarini Zabbey, professor of biomonitoring and restoration ecology at the University of Port Harcourt’s Department of Fisheries.
AMERICAS A Health Check for South American Mangroves Meet Jaragua´s galliwasp: New mangrove lizard species discovered by Dominican project partners DOMINICAN REPUBLIC – Seacology’s efforts to protect mangrove forests in the Dominican Republic can claim a lot of milestones: a dozen projects, our national initiative to engage the public about the importance of these ecosystems, educational events, a sports-and-conservation program that have reached thousands of kids, and more. But it’s not every day we can say we were involved in the discovery of a new species. Late last year, biologist Miguel Landestoy and his colleagues were observing reptiles around Oviedo Lagoon as part of a survey organized by Grupo Jaragua, our national project partner. The researchers were collecting data on the biodiversity of the mangrove area, to aid in the development of informational materials for a public outreach campaign (known locally as Campaña ManglarES). While exploring Cayo Iguana—a small cay in the lagoon named for its abundant population of rhinoceros iguanas—something new caught their attention. A medium-sized brown lizard was scurrying among the rocks, fallen leaves, and twisting mangrove roots. A less knowledgeable observer might have mistaken it for one of its close cousins like the common Hispaniolan galliwasp (one of a group of ground lizards locally known as lucias). But Landestoy and his colleagues noticed its larger ear openings and webbed toes, and realized they might be looking at something new.Regulating mangrove responsibility causes confusion ASIA As livelihoods clash with development, Vietnam’s Cần Giờ mangroves are at risk VIET NAM – At night, waves crash into the rocky barricades running along the coast of Cần Giờ, a refuge of mangroves and beaches in the southernmost reaches of Ho Chi Minh City. As the sun rises, the waves recede, leaving a damp but navigable plain stretching 2 kilometers (1.2 miles) offshore. For about 30 years, Thiệu has risen as the water ebbs to search the shores for small holes in the sand where clams are likely burrowed. Twice a year, he’ll bring a sack of pinhead-sized baby clams and place them on the shore, in hopes that they’ll grow into larger shells he can harvest in a few months. But if one of Vietnam’s biggest corporations carries through with its plans, Thieu and the fleet of clam collectors along this beach will lose their livelihoods, and Cần Giờ’s longest stretch of coastline will be filled with sand and sculpted into luxury tourism resorts and housing. Cần Giờ’s mangrove forests and beaches have made the district a “green lung” for the pulsating city. The 75,740-hectare (187,158-acre) forest serves as a crucial carbon sink, a defense against surging seas, and a place for urban tourists to shed their stress and tension. At present, visitors arrive from the city by ferry, staying in small towns tucked into the mangroves and driven by aquaculture and small-scale tourism.Meet the UAE’s first female aircraft engineer who created a mangrove forest

GUYANA – Mangroves are a crucial protector against climate change’s effects in Guyana’s low-lying coastal regions. In addition to being rich habitats for wildlife in this northern South American country, these swampy forests help block floods and pounding surf as sea levels rise and storms intensify due to climate change. Mangroves also help stop erosion, prevent saltwater from seeping into agricultural soils, and act as a carbon sink, absorbing more carbon than most inland rainforests. To ensure that these habitats stay healthy, the Mangrove Monitoring Service was launched in July 2022 by SERVIR, a joint program of NASA and the U.S. Agency of International Development. This new monitoring effort is in collaboration with Guyana’s National Agricultural Research and Extension Institute and the University of Guyana. It measures the height and density of mangrove forests by using NASA satellites that bounce radar signals off the planet’s surface. When these lasers hit mangroves’ leaves and branches, the radar signals come backscattered. When the radar signals bounce back more smoothly, it can warn local experts that a section of forest might be sick, or even deforested entirely. The Mangrove Monitoring Service also uses imagery from other NASA satellites, and this bird’s eye view of the forests further helps spot places where forest is being lost.
