Marine conservation in the Indian Ocean

Introduced by Jeff Goodman
Each year more people look for exotic destinations to take their holidays and dive trips and so the human impact on these pristine places takes a terrible toll. Reef destruction, over fishing, uncontrolled development, pollution from human waste… the list is almost endless. So who is ultimately responsible? Local government? Tour operators? Resort companies? Tourists? We all tend to pass the buck while at the same time making as much profit as possible before the golden goose eventually gets choked to death. In the Maldives at least, these issues are starting to be being taken seriously.
The Maldives, called “the flower of the Indies” by Marco polo, is suffering today from new developments and an increased population, including tourism, which together with climate change will synergistically impact on the marine environment.
The Maldives constitutes together with the Laccadives the largest and most extensive chain of atolls on the planet with less than 4% of the territory being dry land, so by joining the two most important forces that drive the country together, conservation and tourism, a long term sustainability of the marine environment can be obtained.
This country is the most imminently threatened by rising seas caused by climate change, so the Maldives has to be prepared for climate change as past emissions will increase global temperatures by up to 0.60º C over the next four decades, so not only must our awareness of climate change increase, so must our need to understand the changes it will bring and our vulnerability to it. Other activities practiced in the Maldives such as coral mining, pollution and unregulated fishing are already impacting on the marine environment, so understanding the effects of temperature increase and ocean acidification is of extreme importance.
A country that is no longer relying on their tuna fishery for survival but depend on resort islands and incoming tourists for their livelihoods have to take care of their environment.
Speaking about the tourism in Male, Kuoni’s Head of Corporate Responsibility Matthias Leisinger once said that “tourism is like fire; you can cook with it, but it can also burn your house down.” The tourism industry generates about 30% of the country´s GDP. In 1998 a bleaching event caused almost 100 percent of mortality in some areas of the coral reefs and, compared to other countries where management was working really well, their recovery was much better than in the Maldives. “Incidents like this are likely to increase as stock diminishes everywhere” says another representative from the Ministry of Tourism in the Maldives. He also pointed out new challenges arising with the changing market profile of tourism in the country, since the European visitors do form part of taking care of the natural environment. However, “the market is changing, and the new market is constituted of guests that are walking on the reefs, catching and eating crabs….” “Maybe it is about time for the resorts “to take responsibility for the natural environment for the duration for the lease,” a representative from the Marine Research Centre (MRC) said. Adjustment is essential if the different sectors, including tourism, aim to reduce the vulnerability to climate change and limit its negative sides and so optimizing the resources to the local community to cope with these changes.
The two biggest threats to the Maldives are climate change and waste management.
Climate change and coral reefs resilience
● Coral Reefs in the Maldives
– The Maldives is home to around 60 different coral genera and has the highest coral diversity in the Indian Ocean. Perhaps due to its substratum or erupted lava, the Maldivian reefs appear to be qualitatively different from other shallow reefs in the Indian Ocean in the way that they are composed of branching Acropora in high abundance and diversity. The Maldives also have the highest temperatures of the Indian Ocean.
– The threats the coral reefs are facing in the Maldives are sedimentation and sewage stress from the bigger islands (from the harbors and airport). In addition to this, inappropriate fishing methodologies are increasing and impact the recovery rate of the reef from bleaching events, and together with the global climate change is the biggest threat nowadays. The impact and the long-term possible recovery of reefs are directly related to overall health of coral reefs.
– For local and national managers to be able to act in response to these threats it is therefore of extreme importance to have monitoring protocols.
Monitoring Protocols
A number of protocols have been developed by the Marine Research Center, the Darwin Initiative, and the Great Barrier Marine Park Authority to monitor reef fisheries and coral bleaching in which corals expel the algal cells (zooxanthellae), that under normal conditions live within their tissue. The Maldives has already experienced extensive climate related damage to their reefs, where other reefs recovered better under similar circumstances, therefore an accurate management and understanding of Coral Reef health has to be implemented around the whole country.
Bleach Watch
This protocol has been developed to detect and measure conditions and events of coral bleaching from a wide range of users like dive operators and resort staff, who over time can prepare available, reliable reports. Detecting early signs of mass bleaching events require a wide network of observers over a broad span of territory.
CPC
Counting the coral coverage and the coral diversity across the Maldives over time will provide the national government and resort managers with valuable information which can be used to understand and act in response to observed changes and threats to coral reef around the Maldives.
Reef Fisheries and the Darwin Reef Fish Project
It is important for the Maldives to obtain more knowledge about reef and fisheries in order to develop new management plans to maintain the Coral Reef’s health. The reef fish are important through herb ivory and predation and both overfishing and destructive fishing practices can alter the dynamics of the whole ecosystem. The Darwin Reef Fish Initiative together with the MRC have developed a new resources management plan, where spawning aggregations and fish home range can be detected to elaborate new management plans. The aquarium and bait fishery have guidelines, but there are no regulations for reef fish, apart from the protected Napoleon wrasse and parrotfish species. The reef fishery has to be managed properly to be sustainable and size limitations of reef fish are necessary, so by implementing this monitoring protocol, miss-reporting and under-reporting fish, like the Rainbow runner, is being sampled and measured to apply appropriate managing guidelines and so improve the resilience of the Coral Reefs.
Fish watch
A fish count and underwater visual census; it constitutes a tool to measure fish populations over time and location.
Fish Catch
A survey collecting information on number and weight of landed reef fish. Together with the measured size and the location of fishing, this gives information for developing marine protected areas. Data is also collected from night fishing practiced by guests of the resorts.
Shark Watch
A diver or snorkel-based recording of shark sightings at the dive or snorkel site on a daily basis. Since the sharks were almost depleted from its water or overfished due to their fins, the tourists are now demanding to see sharks, so since 2009 they have introduced shark protection.
Under the climate change trust fund with World Bank funding a new project is being implemented that will train and empower local community to monitor their coral reefs until September 2014.
A monitoring protocol is developing and a database is going to take shape for the entire country. With less than one per cent of the world’s oceans protected from exploitation and an estimation of that up to 80% of the world´s marine protected areas are only so called and not actively managed, it´s of urgent need to create properly managed and protected areas for the marine environment. All benefits of having marine protected areas are well known, such as conservation of the biodiversity and improvements of the local economy; however, it is so important for the future of the country, which is why a stakeholder approach is needed to monitor these areas and, if necessary, protect and preserve them.
Another issue to consider is how close they need to be, in order to promote connectivity between areas, and how many there should be, to provide a real protection for species. To enhance the resilience of the coral reef in the Maldives not only a reduction on pollution is needed, but also protection and managing existing marine areas properly, can work as an insurance for sustainability.
● Developing waste management systems on inhabited islands
– The Maldives is facing one very big human impact and that is waste management. In the shadow of Thilafushi Island, which is the waste island close to Male the capital, the local islands are struggling with waste processing and associated water quality problems. The Maldivian islands are scattered over a very large area, so distance combined with an increase in population and consumption make the waste management issue very important to resolve.
– A pioneer project involving four northern atolls cooperating to manage the waste at just one island is set up to start working in 2014. This will join resort islands and local islands together, and act as a pioneer project to relieve the burden of Thilafushi.
– By promoting this and taking care of waste closer to the islands where it originated, it is probable that less waste will be dumped in the ocean or buried in the sand or burned producing toxic gases.
– So by doing this, not only will the local islands’ reefs get more resilient by alleviating the human impact, but also the resort island will have less waste washed up on their beaches. This is a good example of both locals and tourists benefitting and eventually the entire economy and the environment.
– Money from separate sources will also be implemented in several projects to teach segregation of waste at household level, and bins will be provided to store the waste separately until removal from the island.
– Probably due to the fact that the islands have accumulated waste over time, a big clean up has to be organized to accomplish the objective of waste management.
The Maldives aims for a total protection of their waters and would like to proclaim the entire country a UNESCO biosphere reserve by 2017 and the country as a Marine Reserve by 2020. Let´s see how this amazingly beautiful country threatened by climate change and waste will manage with such big expectations.

Book Review: Into the Great Wide Ocean

Into the Great Wide Ocean: Life in the Least Known Habitat on Earth by Sonke Johnsen
What an unexpected surprise! A book that combines a clear passion for the ocean with humour and the deft touch of a true storyteller. Johnsen gives a wonderful insight into the life of a deep sea marine biologist , the weird and wonderful animals encountered in this mysterious world, the trials and tribulations, in a way that makes you feel you have been sat at a table chatting about his work over a pint or cup of tea.
Even for divers, the deep blue open ocean can feel inaccessible. It is one of the least studied places in the universe. In this book that deep blue ocean and its inhabitants is brought to you with warmth and wit. And even the most well-read will come away with new facts and information. Johnsen’s goal is one that resonates throughout: Before we as scientists can ask people to preserve this important and fragile habitat, we need to show them that it’s there and the beauty of what lives in it. He does just that.
This is a book that combines the scientific with a deeply personal story. You feel what it is like to work out in the open ocean and get to know the animals that reside there. With descriptions that allow you to really imagine what it feels like being out there in the blue.
What the publisher says:
The open ocean, far from the shore and miles above the seafloor, is a vast and formidable habitat that is home to the most abundant life on our planet, from giant squid and jellyfish to anglerfish with bioluminescent lures that draw prey into their toothy mouths. Into the Great Wide Ocean takes readers inside the peculiar world of the seagoing scientists who are providing tantalizing new insights into how the animals of the open ocean solve the problems of their existence.
Sönke Johnsen vividly describes how life in the water column of the open sea contends with a host of environmental challenges, such as gravity, movement, the absence of light, pressure that could crush a truck, catching food while not becoming food, finding a mate, raising young, and forming communities. He interweaves stories about the joys and hardships of the scientists who explore this beautiful and mysterious realm, which is under threat from human activity and rapidly changing before our eyes.
Into the Great Wide Ocean presents the sea and its inhabitants as you have never seen them before and reminds us that the rules of survival in the open ocean, though they may seem strange to us, are the primary rules of life on Earth.
About the Author:
Sönke Johnsen is professor of biology at Duke University. He is the author of The Optics of Life: A Biologist’s Guide to Light in Nature and the coauthor of Visual Ecology (both Princeton). Marlin Peterson, who created original illustrations for this book, is an illustrator and muralist who teaches and illustrates in many styles and media. He also specializes in giant optical illusions such as his harvestmen mural below the Space Needle in Seattle, and his full portfolio can be found at marlinpeterson.com.

Monty Halls is backing this week of fundraising “Cousteau called sharks the “splendid savage of the sea”, and even through the more benign lens of modern shark interactions it remains a good description. The reefs I dived thirty years ago teemed with sharks, the perfect result of 450 million years of evolution. Today those same reefs are silent, the blue water empty of those elegant shadows. But hope remains that if one generation has created such devastation, so the next can reverse the damage that has been done. The Shark Trust are at the forefront of that fight.“
