Final throes for Jamaica's 'Hippie Paradise'?

From an article by Kathy Barrett on ipsnews.net:

For centuries, Negril, a seven-mile stretch of white sand beach on the western tip of Jamaica, was cut off from the rest of the island by bad roads and a large swamp.

It remained relatively unknown to the world until the 1960s and 1970s, when U.S. "hippies," students and Vietnam veterans gravitated towards this laid-back village.

The U.S. travellers arrived in ever-increasing numbers and, towards the end of the 1970s, Negril blossomed as a tourist destination. But with the growing population and improved infrastructure, the natural beauty of Jamaica's third largest tourism centre has suffered visible deterioration.

"When I first visited Negril from Kingston in 1960, just after the first road to the coast was built, there were no buildings the entire length of the beach. The waters were crystal clear," wrote Thomas J. Goreau, president of the non-governmental U.S.-based Global Coral Reef Alliance, in a paper published in 1992.

"Now that it is Jamaica's fastest growing resort area, all the tall coconut trees are gone, the beaches are crowded with people and buildings," states the text.

Eighteen years later, the demise of the Negril environment has again been brought into sharp focus, this time by United Nations Environment Programme (UNEP) Division of Early Warning and Assessment.

Expert Pascal Peduzzi, who heads the Early Warning Unit, predicted in March that several beaches on the western end of Jamaica could be totally wiped out in the next five to 10 years if local authorities and residents do not act now.

His prediction is based on data coming out of a UNEP study on the role of the ecosystem in disaster risk reduction.

"The data has found that beaches in Negril are receding between half and one metre per year," said Peduzzi.

The scientific evidence shows that over the past 40 years Negril's beaches have undergone severe and irreversible shoreline erosion and retreat, according to the study entitled "Risk and Vulnerability Assessment Methodology Development Project (RiVAMP): The Case of Jamaica."

"The highest erosion rates have occurred after 1991, when beach recovery after storms has been slower, and these trends are likely to continue," Peduzzi said.

The UNEP report says bad environmental and building practices and illegal dumping of pollutants in the sea were killing sea grass and coral reefs, thus reducing their effectiveness in protecting the beaches from erosion. . . .

Jamaica's beaches in danger, says UN expert

From an article in the Jamaica Observer by Kimmo Matthews:

A United Nations environmental expert is predicting that several beaches on the western end of Jamaica could be totally wiped out in the next five to 10 years if local authorities and citizens do not act now to protect the environment.

Pascal Peduzzi, head of the Early Warning Unit, United Nations Environment Programme (UNEP)/Division of Early Warning and Assessment/GRID-Europe, based his prediction on data coming out of a UNEP study on the role of the ecosystem in disaster risk reduction.

"Coming out of the study, data has been found that beaches in Negril are receding between 0.5 and one metre per year," Peduzzi told the Observer after the study was presented to the Government at the Terra Nova Hotel in Kingston recently.

According to the study, titled 'Risk and Vulnerability Assessment Methodology Development Project (RiVAMP) -- The Case of Jamaica', scientific evidence shows that over the past 40 years, Negril's beaches have been experiencing severe and irreversible shoreline erosion and retreat.

"Bloody Bay in the northern section of Negril has experienced lower erosion rates than Long Bay, with sections of Long Bay beach without coral reef cover showing higher rates of erosion," the study said. "The highest erosion rates have occurred after 1991, when beach recovery after storms has been slower, and these trends are likely to continue. It is expected that long-term sea level rise, changing patterns of tropical storms and cyclones in the region (in terms of both frequency and intensity), diminishing sand supplies due to coastal ecosystem degradation as well as coastal development will exert an even higher toll on Negril's beaches."

According to Peduzzi, not only were these findings a cause for concern, but there was a strong belief that other areas across the country could be experiencing the same problem.

Caribbean ecocide or where did the Cancun and Playa Del Carmen beaches go?

From a post on YUC Director, "your guide to Merida and Yucatan:"

Looking out across the dark Caribbean night from Punta Allen one sees three equally sized glowing areas on the distant horizon to the north. The furthest out is Cancun, the next Playa del Carmen and the last Tulum.

Cancun has a bit less than a million people; Playa has 300,000 and Tulum now over 30,000. Playa Del Carmen is the fastest growing municipality in Mexico.

But from Punta Allen each lighted area appears to be the same size since Cancun is farther away than Playa and Playa is farther away than Tulum. The three groups of lights are a reminder of the environmental impact of civilization, including light pollution.

In the next 20 years these three lights will merge.

Biologists report the coral reefs are dead out from Cancun, dying off the coast of Playa Del Carmen and starting to die off Tulum. Progress, people and pollution are taking their toll.

If the reefs die, scuba diving will go soon thereafter and that is a major source of tourist dollars. Scuba diving, unlike snorkeling, is not cheap.

The turtles are also moving south. Cancun has too much activity so the turtles are moving down the Riviera Maya coast and eventually will all move into the Sian Ka’an biosphere reserve.

The turtles are of course protected and the cute critters even have a radical environmental group just to make sure they stay around.

But many other creatures, like the pink conch and the jaguar, are slowly dying off as well. Such is progress.

The beaches too are dying.

Hurricane Wilma devastated the beaches on the Cancun strip and the replaced sand was not white and had broken shells in it and was not pleasing to the tourists.

Playacar Resort in Playa del Carmen is now being overtaken by water as the beach has totally washed away. Que pasa?

Hurricanes and storms seasonally move through the coast causing widespread damage and beach erosion.

WILD9 adjourns with call to protect half of the planet

From a post on the blog of The Wild Foundation:

The week-long WILD9 congress concluded with the launch of a vision that humanity should move immediately to protect a least half of planet — land and sea — in an interconnected manner.

“That is what the science says; this is what many aboriginal people say. It is time for us to state clearly the scale of conservation intervention needed to make the 21st century one of hope instead of despair,” said Harvey Locke, The Wild Foundation vice president of conservation strategy, in the closing plenary session.
The launch of this vision built on a host of resolutions, strategies, initiatives and united support for international wilderness protection as the essential foundation of a healthy planet by more than 1500 conservation leaders and delegates from 51 countries representing academia, government, the private sector, science, native peoples, the arts, media and social sciences.

During WILD9’s opening ceremony Nov. 6, Mexico President Felipe Calderon announced a ground-breaking trilateral agreement between Mexico, the U.S. and Canada to cooperate on wilderness protection– the first time countries have formally agreed to collaborate on continent-wide conservation measures to protect ecosystems, migratory wildlife, and natural resources that do not start and end with geographical boundaries.

Both President Calderon and Yucatan Governor Ivonne Ortega Pacheco committed to increase the amount of protected wild areas including fragile and critical mangrove habitat on the Yucatan peninsula, emphasizing the new concept in Latin America of “tierras silvestres.” President Calderon underscored Mexico’s commitment to wilderness by canceling the first issue of the country’s first series of postage stamps featuring wild areas during WILD9’s opening night events.

WILD9 chairman Exequiel Ezcurra and WILD9 executive committee embodied the mission and character of WILD9 in The Merida Message (Mensaje de Merida), released Nov.10, which calls for the protection of critical land and sea wilderness areas to mitigate climate change and conserve biodiversity and healthy ecosystems that provide products and services vital to human well-being. Many of the world’s leading conservation organizations and hundreds of individuals have already signed The Merida Message, which will be presented at the Copenhagen UNFCC climate change talks next month.

Investment in ecosystems will reap rewards: UNEP

From a Reuters article by Nina Chkestney:

LONDON (Reuters) - Nations that take into account natural resources in their investment strategies will have higher rates of return and stronger economies, a report backed by the United Nations' Environment Programme said on Friday.

With less than one month until a U.N. climate summit in Copenhagen, the report urges policymakers to reform their economic policies to stop the destruction of natural resources such as forests and oceans.

"Repairing the ecosystem by replanting forests, restoring mangroves along coastlines or rebuilding coral reefs are very smart ways of doing adaptation. People going into Copenhagen are not necessarily aware of these things," Pavan Sukhdev, the leader of the study prepared by UNEP's Economics of Ecosystems and Biodiversity Initiative, told Reuters.

For example, planting and protecting nearly 12,000 hectares of mangroves in Vietnam costs over $1 million but it saves over $7 million in dyke maintenance expenditure.

The report estimates that investment in mangrove and woodland restoration could achieve rates of return up to 40 percent, tropical forest investment up to 50 percent and grassland investment 79 percent.

"We studied the economics of using nature better -- through adaptation and restoration. In each case we found the benefits exceed the cost, typically between 3 and 75 times," Sukhdev said.

Coastal habitats may sequester 50 times more carbon than tropical forests by area

"I took a journalist interested in mangroves into a small lagoon where juvenile sharks could be found. Instead of finding sharks, we found a backhoe dredging a large sand spit across the lagoon. The work was being done without sediment traps and as we later found out, without permits. One mangrove shoot stood in the eventual path of the backhoe and I decided to get a shot of it standing tall - both condemned and yet defiant to the bitter end." Photo and explanation by Matthew D Potenski, MDP Photography/Marine Photobank.

From an article by Jeremy Hance on Mongabay.com:

Highly endangered coastal habitats are incredibly effective in sequestering carbon and locking it away in soil, according to a new paper in a report by the IUCN. The paper attests that coastal habitats—such as mangroves, sea grasses, and salt marhses—sequester as much as 50 times the amount of carbon in their soil per hectare as tropical forest.

"The key difference between these coastal habitats and forests is that mangroves, seagrasses and the plants in salt marshes are extremely efficient at burying carbon in the sediment below them where it can stay for centuries or even millennia. Tropical forests are not as effective at transferring carbon into the soil below them, instead storing most carbon in the living plants and litter," explains the paper's author and Conservation International’s Marine Climate Change Director, Dr. Emily Pidgeon. "But coastal ecosystems keep sequestering large amounts of carbon throughout their life cycle. Equally, the majority of carbon stays locked away in the soil rather than the plant, so only a relatively small amount is released when the plant dies."

This capacity for coastal environments to lock away carbon for thousands of years has largely been ignored in accounts of the global carbon cycle, according to the paper, even though the amount of carbon they are responsible for storing is very high.

Coastal habitats with vegetation "[contribute] about half of the total carbon sequestration in ocean sediments even though they account for less than 2 percent of the ocean surface,” Pidgeon writes, explaining that much of this is capacity is due to the fact that coastal vegetation usually spreads deeper below ground than it grows above with some plants going as deep as eight meters.

Support the Caribbean Challenge

An appeal from The Nature Conservancy:

In May of 2008, The Bahamas’ government, alongside leaders from Jamaica, the Dominican Republic, and St. Vincent and the Grenadines launched the Caribbean Challenge, a region-wide campaign to protect the health of the Caribbean’s lands and waters. Today, eight Caribbean nations have committed to protecting nearly 20 percent of their marine and coastal habitat by 2020.

The Caribbean Challenge will result in a wholesale transformation of countries’ national park systems and will nearly triple the amount of marine and coastal habitat currently under protection, setting aside almost 21 million acres of coral reefs, mangroves, sea grass beds and other important habitat for sea turtles, whales, sharks and other wildlife. The three core components of the Challenge include:

•creating networks of marine protected areas expanding across 21 million acres of territorial coasts and waters

•establishing protected area trust funds to generate permanent, dedicated and sustainable funding sources for the effective management, expansion and scientific monitoring of all parks and protected areas

•developing national level demonstrations projects for climate change adaptation
Modeled on other large-scale conservation financing efforts, including the Micronesia Challenge and the Great Bear Rainforest in British Columbia, the Caribbean Challenge goes far beyond piecemeal, incremental conservation. The campaign to meet the Caribbean Challenge is a campaign to end paper parks in the Caribbean forever.

To support the Challenge, the Conservancy has pledged $20 million in cash and in-kind resources to endow national protected area trusts and provide technical support. . . .

Happily, the Challenge offers an opportunity to profoundly change that projected future of loss into a realized future of abundance. Please join us as we work to fulfill our $20 million pledge to help protect 21 million acres of the Caribbean and all of the plants, animals and people who depend upon those clear waters for survival.

With your help, the Caribbean Challenge can make an immediate and material difference to the future of the plants, animals and people of the Caribbean. Please join us. Your contribution matters.

Mexico shuts Cancun beach, alleges sand was stolen

From an Associated Press article by Mark Stevenson:

MEXICO CITY — Surprised tourists found their little piece of Cancun beach paradise ringed by crime-scene tape and gun-toting sailors on Thursday.

Environmental enforcement officers backed by Mexican navy personnel closed off hundreds of feet (dozens of meters) of powder-white coastline in front of a hotel accused of illegally accumulating sand on its beach.

Mexico spent $19 million to replace Cancun beaches washed away by Hurricane Wilma in 2005. But much of the sand pumped from the sea floor has since washed away, leading some property owners to build breakwaters in a bid to retain sand. The practice often merely shifts sand loss to beaches below the breakwaters.

"Today we made the decision to close this stretch of ill-gotten, illegally accumulated sand," said Patricio Patron, Mexico's attorney general for environmental protection. "This hotel was telling its tourists: 'Come here, I have sand ... the other hotels don't, because I stole it.'"

Patron said five people were detained in a raid for allegedly using pumps to move sand from the sea floor onto the beach in front of the Gran Caribe Real Hotel. The hotel is also suspected of illegally building a breakwater that impeded the natural flow of sand onto other hotels' beaches, he said.

Protection of land crabs critical to the conservation of coastal tropical forests

From an article by Morgan ERickson-Davis and Jeremy Hance on Mongabay.com:

The impact of land crabs on the near-ocean forests in which they live has long been overlooked, with emphasis placed instead on water levels, salinity, and other abiotic influences. However, a new research synthesis published in Biological Reviews shows that land crab influence is among the most important factors affecting tropical forest growth along coasts, on islands, and in mangroves.

Land crabs come in a variety of species from the tiny Ecuadorian Hermit Crab, which weighs less than an ounce, to the Coconut Crab which, at 38lbs, is the world's largest terrestrial invertebrate. While many species are similar in appearance to their aquatic relatives, land crabs exhibit an array of unique adaptations, the most notable and universal being an inflatable organ covering their gills which acts as a lung. In addition to an ability to extract oxygen from the air, many species of land crabs can extract moisture from their surroundings (from the soil they burrow into or the food they eat, for example), necessitating their return to the sea only to reproduce.

Most species of land crabs are omnivorous and can have quite an impact on terrestrial vegetation, so much so that many populations have become pests to farmers who grow crops near tropical coasts. Even so, the crabs' role in the development of coastal ecosystems has only begun to be understood. "Land crabs are found in coastal forests which have been understudied due to inaccessibility in remote areas and habitat loss (deforestation) in developed areas." says Dr. Erin Lindquist, professor at Meredith College and coauthor of the recently published synthesis. "In addition there has been little groundwork on the natural history of land crabs."

However, recent research has begun to reveal the true nature of the crabs' impact on their environment.

Unstoppable devastation of Guatemalan mangroves

Fringing red mangrove (Rhizophora mangle) are an essential nursery habitat for coral reef species. Uncontrolled coastal development in the Caribbean is threatening the survival of both mangrove and coral reef communities. The Dominican Republic today is one of the hot spots of major habitat destruction in the region, followed closely by the Mexican Caribbean. Photo by Dr. Sarah Frias-Torres/Marine Photobank

From an article by Danilo Valladares in Tierramérica:

GUATEMALA CITY, Jul 13 (Tierramérica).- "Before, this place was beautiful. It was truly a mangrove forest. When the shrimpers arrived, the logging meant that we lost 60 percent of it," said Francisco Vásquez, manager of a hotel on the Pacific coast, in the southeastern Guatemalan department of Jutiapa.

The deforestation led to sedimentation and has had a visible effect on the animals, because the mangrove forests serve as a sanctuary for the reproduction of many species, including fish, mammals and migratory birds," Vásquez told Tierramérica.

According to a study by the Savia School of Ecological Thought, in the past 50 years this country of 108,889 square kilometers lost two-thirds of its original forested area and the biodiversity that it held. The current rate of deforestation is 73,000 hectares per year.

The disappearance of forests has reduced the natural ability to regulate climate and increased the risk of landslides. Furthermore, entire ecosystems have been lost, with their flora and fauna, as well as the capacity to capture, filter and store water resources, warns the study.

The case of the mangroves is one of the most dramatic, according to ecologists. "Many mangroves are destroyed by agro-industrial activities, cotton, African palm, shrimp farms, and, more recently, the construction of tourism complexes," Carlos Salvatierra, an expert with the Savia School, told Tierramérica.

Mangrove forests, which grow in coastal zones of tropical countries, "constitue one of the planet's most productive ecosystems for the great quantity of animals it houses - birds, mammals, mollusks, crustaceans, which are important for the livelihood of local communities," he added.

The tangled form of the mangrove tree, or bush, acts as a natural barrier that filters out pollution, impedes salinization of the soil, prevents erosion and blocks strong winds.

From an article posted on the Environmental News Service:

NEW YORK, New York, June 8, 2009 (ENS) - Human activities are taking a "terrible toll" on the world's oceans and seas, UN Secretary-General Ban Ki-moon warned today in a message marking the first United Nations World Oceans Day.

"Vulnerable marine ecosystems, such as corals, and important fisheries are being damaged by over-exploitation, illegal, unreported and unregulated fishing, destructive fishing practices, invasive alien species and marine pollution, especially from land-based sources," said Ban.

Increased ocean temperatures, sea-level rise and ocean acidification caused by climate change pose further threats to marine life, coastal and island communities and national economies, he said.

Turneffe Atoll Biodiversity Initiative

From an initiative of the Ocean Society:

Turneffe Atoll is the largest and most biologically diverse coral atoll in the Western Hempisphere. Located 25 miles east of Belize City and isurrounded by deep oceanic waters, Turneffe is approximately 30 miles long and 10 miles wide.

The islands, some larger than 5,000 acres, are covered by at least 77 different vegetation types. Mangrove forests are interspersed with brackish lagoons, covering most of the low-lying areas. A reef crest and magnificent shallow coral buttresses is followed by reef rim on the outer reef drop-off.

Biological Significance
Turneffe's healthy reefs support diverse species including the endemic white spotted toadfish and white lined toadfish. The abundant sponges offer rich feeding grounds for the endangered hawksbill sea turtle and atoll beaches serve as nesting sites for loggerhead and green sea turtles. Historically, Blackbird Caye South was known to have the largest sea turtle nesting site on the Atoll, and in recent years, loggerhead turtles have successfully nested at the Blackbird Oceanic Field Station beaches. . . .

Threats
Until 2000, commercial development at Turneffe consisted of small-scale dive resorts and a fishing resort. However in recent years, transfer of land from public to private ownership has escalated deforestation of prime natural habitats. Lack of protection for the largely in-tact natural forest and clearing for developments presents the greatest threat to the survival of all terrestrial wildlife on Turneffe.

Rainbow parrotfish the largest herbivorous fish in the Atlantic Ocean are totally dependent on mangrove nursery areas and are becoming locally extinct in some locations due to mangrove clearance, which also threaterns reef health through algal overgrowth.

Illegal fishing is a growing problem, exacerbated by the lack of any enforcement presence on the atoll. In particular, it involves the harvesting of undersized and out of season marine species. Illegal fishing gear can harm nontarget species such as manatees and sea turtles.

Nutrient pollution chokes marine and freshwater ecosystems

From an article posted on Science Daily:

ScienceDaily (Feb. 19, 2009) — Protecting drinking water and preventing harmful coastal "dead zones", as well as eutrophication in many lakes, will require reducing both nitrogen and phosphorus pollution. Because streams and rivers are conduits to the sea, management strategies should be implemented along the land-to-ocean continuum. In most cases, strategies that focus only on one nutrient will fail.

These policy recommendations were put forth by a team of distinguished scientists in the recent issue of Science, published February 20. Led by Dr. Daniel J. Conley, a marine ecologist at the GeoBiosphere Science Centre in Sweden and a Visiting Scientist at the Cary Institute of Ecosystem Studies, the paper reviews weaknesses in single-nutrient management strategies. In most cases, improving water quality and preserving coastal oceans will require a two-pronged approach.

Plant growth is tied to nitrogen and phosphorus availability. Human activities have greatly increased the abundance of these nutrients, causing the overproduction of aquatic plants and algae. Nitrogen pollution is largely derived from agricultural fertilizers and emissions from the combustion of fossil fuels. Phosphorus pollution is tied primarily to wastewater treatment and detergents. Inputs to the landscape make their way to coastal areas through the drainage networks of rivers and streams.

Dr. Gene E. Likens, one of the paper's authors and an ecologist at the Cary Institute of Ecosystem Studies, comments, "Historically, environmental management strategies in freshwater systems have focused on reducing phosphorus pollution. While this has minimized freshwater algal blooms [like this one off the Yucatán Penninsula], it passed a great deal of nitrogen pollution on to coastal ecosystems, driving eutrophication and causing serious and widespread problems in those regions."

These environmental problems include reductions in the oxygen levels of coastal water, which can cause "dead zones" and fish die-offs; the proliferation of undesirable plant growth; reductions in water quality; and the loss of important coastal fish habitat, such as sea grass and kelp beds.

Bahamas reserve protects marine life from resort developers

From an article by Juliet Eilperin in the Washington Post:

The Bahamas government has created a marine reserve off the island of North Bimini, preserving critical mangrove habitat and a shark nursery that had come under threat from a resort there.

The reserve, which will be protected from most fishing and other "extractive activities," is home to endangered species such as the Nassau grouper and the Bimini boa, as well as a vibrant nursery for lemon sharks.

The decision -- approved by the Bahamas cabinet Dec. 29 but announced last week -- is a setback for the Bimini Bay Resort and Marina, which has been clearing some of the island's mangroves to build a hotel, a golf course, a casino and two marinas, some of which have already been constructed.

Prime Minister Hubert Ingraham had initially considered establishing the reserve in the late 1990s, but his party lost power in 2002, and the development proceeded. Ingraham's party won back control in 2007.

From an article by María Miranda Sierra posted on Caribbean Net News:

SAN JUAN, Puerto Rico: On the 15th anniversary of a million-gallon oil spill that damaged the coastline of Puerto Rico, the National Oceanic and Atmospheric Administration (NOAA) and various other organizations are celebrating the purchase of 152 acres to expand a coastal reserve near one of the areas hardest areas hit by the spill on the north eastern part of the island.

NOAA, the Commonwealth of Puerto Rico, and the Trust for Public Land announced Wednesday that 152 acres east of San Juan have been added to the San Miguel Natural Reserve to help compensate the public for lost recreational beach use and injured natural resources for an extended period after the Berman Oil Spill on Jan. 7, 1994.

The purchase of this land expands the San Miguel Natural Reserve to 422 acres, an area the size of 317 football fields, and contributes to a multi-year effort to create the Northeast Ecological Corridor, one of the Caribbean’s last great unprotected areas.

Changes in Land Use, Changes in Climate

From an articleby Emilio Godoy posted on IPS News:

MEXICO CITY, Dec 2 (Tierramérica) - The countries of Latin America have failed to design integrated policies to control the processes of changes in land use, one of the causes of climate change. The region produces 12 percent of the world's emissions of greenhouse gases, which are driving up the planet’s average temperatures and changing the climate around the globe.

Half of the emissions are the result of deforestation, with Brazil and Mexico leading the region in terms of climate-changing pollutants.

"Latin America needs regional integration to combat deforestation," Brazilian Senator Renato Casagrande told Tierramérica.

Change in land use was one of the main issues taken up by 77 lawmakers from across the region at a meeting of the Global Legislators Organisation for a Balanced Environment (GLOBE) that ended Nov. 23 in the Mexican capital.

The event, sponsored by the Mexican Congress, the World Bank, the Alliance of Communicators for Sustainable Development (COM+) and the International Union for Conservation of Nature (IUCN), marked the launch of the International Commission on Land Use Change and Ecosystems.

"We hope that the Commission provides a clear set of measures that national parliaments can adopt through regulations, fiscal incentives or laws," said Casagrande. "That way we can advance towards an economic system that foments a sustainable use of the land."

In their 16-point declaration, the lawmakers stated that deforestation should be a priority in environmental action plans, especially considering the effective and low-cost opportunities associated with the measures and the important parallel benefits for local communities and biodiversity.
Not only does deforestation contribute to climate change, but deforested land can smother the ocean wtih eroded silt, as decribed in an entry on Mongabay.com:
As the suspended particles reach the ocean, the water becomes cloudy, causing regional declines in coral reefs, and affecting coastal fisheries. The loss of coral reefs worldwide, often labeled the rainforests of the sea, is especially distressing to scientists because of their tremendous diversity and the important services they provide. Coastal fisheries are affected not just by the loss of coral reefs and their communities, but by the damage inflicted on mangrove forests by heavy siltation.

British knight backs bid to save Virgin Island mangroves

From an article in The Independent:

Sir Richard Branson is backing a landmark legal challenge by environmental campaigners against a multimillion-pound luxury leisure complex which threatens to destroy some of the most eco-sensitive mangrove swamps in the British Virgin Islands (BVI), the paradise home of the British business tycoon.

The case, which is to be heard in full next year, is expected to have far-reaching consequences for the protection of the fragile Caribbean environment. Sir Richard, head of the Virgin group of companies, has paid for a team of barristers, led by the former chairman of the Bar Stephen Hockman QC, to fly to the group of islands and seek to stop plans to build a marina, five-star hotel and golf course in the British overseas territory.

The Branson family home is on Necker Island, which Sir Richard bought for £180,000 in 1979 and is located just over the water from Beef Island where the development is planned. At threat is one of the most important mangrove systems in the BVI, providing a vital home for hatchlings and juvenile fish, lobster and conch. Under the BVI government plans one of the golf holes is to be sited in the middle of the disputed area.

The Virgin Islands Environmental Council (VIEC), a charity supported by Sir Richard and other interested groups, says it has brought the action to seek legal protection of the environment in the BVI for future generations.

A council spokesman said: "This is a landmark case that addresses a number of important issues which will impact on the future of environmental law and practice throughout the Caribbean. The outcome of this case will definitely impact the way other large projects currently under planning review are dealt with, leading to a more sustainable future for the BVI.
