Maldives plastic recycling on a local islands

Gili Lankanfushi conserves our limited resources and cleans up our islands to help preserve our future.

Following the success of plastic recycling on Gili Lankanfushi we took the leap and expanded our project. On November 2nd Gili Lankanfushi visited Himmafushi, a local island and a big producer of plastic waste due to their plastic water bottle factory. With the assistance of the local NGO Parley, who are spearheading plastic recycling in the Maldives our aim was to implement a plastic recycling project at the school and expand this throughout the island. Together with Parley, the teachers and local council members in attendance Gili Lankanfushi conducted a 30 minute presentation including two activities which all the children participated in. The presentation was well received and the council were positive regarding expanding recycling to all areas of the island. After the school visit 50 staff from Gili Lankanfushi conducted an island plastic clean to demonstrate how easy it is to recycle plastic and what types of plastic can be recycled. A huge amount of plastic was collected and on seeing this the Himmafushi local community has also become inspired to recycle their plastic waste. Gili Lankanfushi will remain in close contact with Himmafushi and offer support and guidance when needed.

 Throughout August 2017 on Gili Lankanfushi 280 hosts attended the sustainability training. Host mentally regarding plastic pollution, water, electricity and food waste has now changed for the better. In addition to Gili Lankanfushi’s plastic presentation Maai Rasheed from Parley visited and conducted a presentation about plastic recycling. Hosts can now be seen regularly recycling their plastic and helping with island cleans – for example the recent Himmafushi clean.

 Following the training activities aimed at increasing host water and electricity use awareness, hosts now know how to reduce wasting these resources through enhanced understanding of water and electricity requirements of common activities. They were given top energy and water saving tips, for example using the fan over the AC, turning off electrical appliances, washing full loads in the washing machine at a low temperature – 20°C, air drying clothing, turning off lights, having shorter showers, only using a small amount of water when cleaning, turning the tap off when brushing teeth, shaving and soaping up. You can make these changes too!

Raising awareness about excessive water waste

 Over the coming months plastic recycling, food waste, electricity and water use will be monitored. In the near future we will host a no bin day in the canteen which will teach hosts about portion and waste control. We have already observed a decrease in water use – before training the average host would use 200L of water per day – this is now reduced to 160L. We are confident that hosts will continue to reduce the waste of resources and participate in plastic recycling.

Coral fluorescence at Gili Lankanfushi

Are corals a shining beacon at night? Corals are not just a wonder to observe during the day, at night they glow. This isn’t just for our viewing benefit; it plays a vital role in the long term survival of coral.

Due to the richness of life they create, corals are often described as the rainforests of the ocean. Their structural complexity supports one of the world’s most productive ecosystems providing ecological diversity and outstanding beauty. The coral animal (polyp) co-habitats its calcium carbonate skeleton with photosynthetic algae called zooxanthellae. These algae harness energy from solar radiation and provide the polyp with 95% of its food. Coral is therefore limited to the habitat range of the algae, which in turn is limited by the penetration of the suns ray into the ocean; both the intensity and spectral diversity of light dramatically decreases with increasing depth. Although the blue/green portion of sunlight reaches depths of around 200m the algae requires the higher light levels found in the upper 30m of the ocean. Corals are therefore limited to the upper portion of the ocean; aptly named the sunlight ocean.

The corals exposure to high light levels is crucial for its survival, but this is not without consequence. The high light intensity that corals are subjected to everyday can damage coral and zooxanthellae – similar to our skin and sunburn. Shallow water corals have a solution to this: fluorescence. The coral contains special pigments (green fluorescent pigments (GFP) and non-fluorescent chromoproteins (CP) which act as sunblock. The fluorescent pigments are in particularly high concentrations and contribute to the beautiful rainbows of colours which can be observed on the reef. When the coral is subjected to high sun exposure the pigment concentration increases, hence limiting the damage experienced by the algae when under stress from sunlight. The pigments are also involved in growth related activities, including repair. Injured coral will produce colourful patches concentrating these pigments around their injury site which prevents further cell damage. Some corals have been found to distribute fluorescent pigments around their tentacles and mouth to attract prey.

 

We are able to observe the fluorescent pigments when corals are illuminated at specific wavelengths (generally blue light). In high pigment concentrations corals can become shining beacons at night. Light is absorbed by the pigments and then re-emitted. During this process some energy is lost resulting in a different colour being observed – generally green. During our blue light night snorkel it is possible to see corals glowing on the house reef at Gili Lankanfushi.

Fluorescence of Porites cylindrica

 

It is now widely accepted that fluorescent pigments aid in sun protection, so why do corals below 30m still have these pigments? In shallow reefs generally only green fluorescence is observed, whereas in the mesophotic zone (between 30 – 100m) corals shine green, orange, yellow and red. Fluorescent pigments are energetically costly to create, therefore the pigments must have a biological purpose, or else they would not exist at this depth. A study carried out by the University of Southampton found that deeper corals produce fluorescence without light exposure, which suggests that these corals are not producing pigments for sun protection. It is suspected that the corals are producing pigments to transform short light wavelengths received into longer wavelengths to enhance algae photosynthesis, thus producing more food for the polyp. It has also been suggested that it may link to behavior of reef fish, although more studies are required. Next time you are night diving take a look. Harnessing these fluorescent pigments could pose significant advances for medical, commercial and ecological purposes.

Many Acropora species also have fluorescent pigments. Credits to: Reef Works

 

Marine biologists at the Scripps Institution of Oceanography at San Diego have suggested that monitoring fluorescence could be an easy and less invasive way to monitor reef health. Scientists measured the fluorescence levels after corals were exposed to cold and heat stress. The levels were reduced when exposed to both stresses, although coral subjected to cold stress adapted and fluorescence levels returned to normal. Corals subjected to heat stress lost their algae and starved. Therefore, if high fluorescence levels are observed it suggests that the reef has a healthy coral population. Additionally there are many medical benefits that can be gained through the understanding and utilization of coral fluorescence. 

 

There are promising applications for biomedical imaging, for example pigments can be used to tag certain cells e.g. cancer cells which can then be easily viewed under the microscope. The fluorescent pigments also have the potential to be used in sun screen. Fish feeding on coral benefit from the fluorescent pigments which suggests that the pigments move up the tropic levels (food chain). Senior lecturer from King’s College London and project leader of coral sunscreen research, Paul Long and his team have suggested that if the transportation pathway up the food chain is identified it may be possible to use this to protect our skin against UV rays in the form of a tablet. This could a break-through in terms of reef safe sun screen.

 

Next time you are night snorkelling shine a blue light on the corals and view this natural wonder yourself!

7 reasons Fulidhoo Island in the Maldives is a dream diving destination

A Maldivian island that’s within easy access from the international airport, but feels remote? It seems almost impossible to find these days. But Fulidhoo Island in Vaavu Atoll is quickly garnering a reputation for being convenient yet secluded. The island is a fantastic base to explore an atoll offering some of the country’s best channel dives and the chance to dive with up to 100 nurse sharks at night. And with rooms starting at 40 US dollars, there’s really no reason not to go. But if you still need convincing, here’s seven reasons why it should be your next diving destination.

Fulidhoo Island Maldives

1. It costs 3.5 US dollars to get there from Male

No, that’s not a typo – you did read that correctly; it costs less than the price of a Starbucks coffee to get to Fulidhoo from the capital. Thanks to the government-subsidised public ferry that departs from Male three times a week, tourists can get to Fulidhoo for virtually nothing. The journey takes three and a half hours, but it’s scenic and comfortable, and there are snacks on board. It even has a sundeck for dolphin watching! Oh, and for those who prefer their transfers a little quicker, there are daily speedboats to the island for around 50 dollars per person that take an hour.

2. Vaavu Atoll is channel diving, sharky heaven

Throughout the Maldives, the passes that cut through the atolls’ barrier reefs are where the real pelagic action is found. Reef sharks, schools of trevallies and barracudas congregate here to hunt. And if the Maldives is known for its channels, then Vaavu Atoll, where Fulidhoo is located, is the country’s channel diving capital. There are dozens of channels in the atoll promising high adrenaline diving.

3. Accommodation on the island is seriously affordable

Whereas resort islands in the Maldives charge eye-watering prices for just one night, because Fulidhoo is a local, inhabited island, divers can find accommodation in one of its small guesthouses for around 50 dollars a night for two people, including breakfast, even during high season. You can expect comfortable, clean, air-conditioned rooms, often with a sea view. And because Fulidhoo is so small, even the furthest guesthouse is only a 5-minute walk to the jetty.

Best local island dive centre

4. The island is famous for its beautiful lagoon and strong cultural traditions

Even among Maldivians, Fulidhoo has a reputation for being extremely beautiful. Vaavu is affectionately known as ‘Wow Atoll’ by locals. There’s no harbour, only a small wooden pier, so the beach is uninterrupted. The shallow lagoon stretches out far from the island and is a great place for kids to play, or to kayak. In fact, the island was recently voted Top Island 2017 at the annual Maldives Guesthouses Conference. And in the evening, divers can enjoy watching the locals play bodu beru (‘big drums’) and performing cultural dances – they’re famous for keeping local traditions alive.

5. You can dive with up to 100 nurse sharks at night

Vaavu Atoll’s most famous dive site is Alimatha House Reef, where divers can get extremely close to the resident nurse sharks and stingrays. As divers kneel on the sandy bottom, it’s not uncommon to see these harmless sharks squeeze between their legs or flop down beside them – it’s truly a bucket list experience!

6. You’ll often be the only divers on the dive site

Unlike South Male Atoll and Ari Atoll, Vaavu is home to only two resorts and only a handful of local islands, which means that the dive sites are far, far quieter. Similarly, liveaboards often head straight to Alimatha for a night dive and are in Ari Atoll by the following morning. All this means that for the most part, the northern part of Vaavu Atoll feels remote and unexplored, despite being extremely accessible.

Fulidhoo Dive Centre Maldives

7. From Fulidhoo, you can dive both the eastern and western sides of the atoll

There are two seasons in the Maldives. The Iruvai season, which runs from November to April, is when the wind generally blows from the North East and brings a hot, dry climate and the best conditions for diving. The Hulhangu season, from May to October, is generally seen as the low-season for diving, with chances of rain, wind and reduced visibility. However, during this season you can still get very good viz on the western edge of the atolls, which is when the location of Fulidhoo comes into play. Because the island is located on the northern tip of the atoll, depending on the wind, divers can enjoy dives with good visibility and good, incoming current throughout the year.

Things you should know if you are travelling to the Maldives on a budget

This blog has several parts, next week read about money and taxes……

With the advent of local island guesthouses and low cost flight carriers there has never been a more affordable time to travel to the Maldives. At Male International airport it is becoming a far more common sight to see guests arriving with backpacks and not matching Louis Vuitton luggage. These travellers are here to experience a destination previously perceived to be only for those seeking luxury. So maybe it’s time you considered putting the Maldives on your travel map!

Whilst budget travel in the Maldives is a growing sector of the tourism industry there still remains limited information available for would be travelers and backpackers. So the team at Secret Paradise put our heads together to provide what we feel are the Top 10 tips every budget traveler should be aware of.

Clearing Immigration and security

To enter the Maldives no pre-arrival visa is required, a thirty day free visa is issued on arrival to all nationalities, provided the following conditions are met:

Be holding a valid passport (requires to be valid for 6 months from date of arrival) and have a valid ticket to continue your journey out of the Maldives

Confirmation of a reservation in a tourist resort or a hotel either in the form of a hotel voucher or online reservation and have enough funds to cover the expenses for the duration of your stay (US$100 + $50 dollars per day)

The right to refuse entry lies at the discretion of the Immigration official, so make it easier for yourself and organise your accommodation prior to your arrival. Online sites such as Booking.Com, Airbnb and Trip Advisor are a great place to start or if you are looking for more of an experience and not just accommodation contact Secret Paradise.

Once you have cleared immigration, collect your luggage and enter the arrivals hall where a representative of the guesthouse or resort should be waiting for you. Importing goods such as alcohol, pork items, pornography, idols of worship and narcotics into the Maldives is strictly forbidden. To make life easier declare the Buddha that you have purchased in Sri Lanka and the bottle of vodka picked up in duty free, the authorities will hold any items declared or undeclared for you to collect as you depart at the end of your stay.

Coral Reef Research at Gili Lankanfushi Maldives

We encourage scientists to visit Gili Lankanfushi to share their knowledge with the Marine Biology team and carry out in-depth research of our local environment.

In an ever changing world, research is an important method of tracking environmental fluctuations and sharing information about our surroundings. After the coral bleaching event of 2016, Gili Lankanfushi wanted to learn more about the damage caused to our beautiful house reef. We hosted a team of experts funded by Rufford Small Grants Foundation, Chiara Pisapia, Dr Morgan Pratchett, and Deborah Burn who assessed the changes on the reef.  They focused on coral cover, coral size, and the number of young corals that have grown on the reef since the bleaching. Morgan Pratchett, the leading expert in Crown of Thorns Starfish (COTS) Ancanthaster planci, also monitored the size, sex and distribution of COTS.

 

The team carried out an initial study in the Maldives in 2016 and then returned to the same sites in 2017 in order to carefully assess any changes in their original findings.  On Gili Lankanfushi’s house reef, the team carried out line surveys at five and ten metres along the drop off and found that after the bleaching, coral cover has dropped to 6% at five metres and 2% at ten metres. This low coral cover is predominantly due to the ocean warming event in addition to COTS predation. Yet, in comparison with other study sites, Gili Lankanfushi had a higher number of coral recruits than expected which means new coral is beginning to grow again on the shallow section of our reef. This results from the hard work of Gili’s Team.

Dr Morgan Pratchett, collected data on COTS around the resort.  Despite their beautiful appearance, COTS are far less captivating once you understand the threat they pose to a struggling reef. They eat the remaining hard corals and new coral recruits. Over the past year, their population has spiked into an ‘outbreak’ therefore they have to be removed from the reef and our team works tirelessly to find each individual. Morgan brought COTS to Gili Veshi, our Marine Biology Lab, to teach us techniques on how to better understand these starfish. By dissecting individuals Morgan was able to show our team the interior of each specimen and explain if the animal was well fed or reproductive.  We were able to highlight certain features under the microscope.  We found the starfish living on our house reef were starving and not yet reproducing which leads us to believe the outbreak is over.

 

The aim of monitoring our house reef over time is to predict and track recovery of different species. We are extremely grateful to the knowledge shared by Chiara, Morgan and Deborah hope they can visit the resort again in 2018 to assess how much our reef has recovered.  We look forward to their return.

Prodivers Cleaned Up the World…

Sunday 17th September 2017 saw millions of people around the world join together for the annual Clean up the World event. Guest and team members of Prodivers on Kuredu and Komandoo joined them.

 

A team of more than 113 guests and staff took part in the event and collected rubbish from the islands, the ocean and the reefs.

A staggering 75 bags were collected as well as lots of pieces of wood and metal. The volunteers were organised into groups and were each given an area to clean.

After the clean-up came the celebration – participants enjoyed a cocktail party held in their honor and were each given a thank you gift of an event t-shirt.

A big thank you to the guests, Resort staff and Prodivers team members who gave up their time for such a good cause – what an amazing team effort.

 

Sun screen: A new threat to a vulnerable reef

Is it our health for theirs? Gili Lankanfushi begins an eco-sunscreen revolution.

Sun screen is a holiday essential – from children covered in a thick layer, to the bald spot on Dad’s head. We think sun screens are safe, but is this the reality? A key ingredient in more than 3,500 sun protection products is oxybenzone. This chemical is absorbed into our bloodstream, can cause allergic reactions and very worryingly was last tested as far back as the 1970’s. It is also possible that oxybenzone may act similarly to a related chemical, benzophenone which attacks DNA when illuminated, and can lead to cancer. Studies are currently being carried out. Annually four to six thousand tonnes of these chemicals enter our ocean through wastewater effluent, and by swimmers slathered up with sunscreen. Acting like an oil slick, the chemicals settle on marine life and the reefs become suffocated.

Reef safe sun screen with no oxybenzone

Corals are animals called polyps that share their home with algae called zooxanthellae. They work together in a symbiotic relationship which means both parties benefit. The coral animal produces a skeleton to shelter the algae whilst building the reef and the algae through photosynthesis provide the coral animal with 95% of its food. In the Maldives, the reefs are under severe external pressure. Sun screen is an added significant hazard which threatens the resiliency of the coral to climate change.

Healthy coral with blue-green chromis population

Bleaching is the term used when coral loses its symbiotic algae; this can happen for a variety of reasons. A study by R. Danovaro and a team of scientists showed that oxybenzone promotes latent viral growth in the symbiotic algae. In the study, fragments of coral were taken throughout the tropics and incubated with seawater containing small quantities of sunscreen (10 microlitres). Bleaching occurred within four days, whereas in the control group which had no sunscreen there was no bleaching. Water samples taken 18 – 48 hours after sunscreen exposure showed that the symbiotic algae, instead of being a healthy brown colour were pale/transparent and full of holes. Additionally viral particles were abundant; 15 times more viral particles where found in water samples exposed to sunscreen than in the control group. This suggests that the coral animal or algae contain a latent virus activated by chemicals in sunscreen. This latent infection is found globally. Oxybenzone is a photo-toxicant, which means that its negative effects are accelerated by light – something which the Maldives does not lack. In other studies, oxybenzone has been found to alter the larval stage of the coral from a healthy swimming state to a deformed motionless condition. It has also been found to cause DNA lesions and endocrine disruption, resulting in coral larvae encasing themselves in their skeletons and dying. The severity of this is proportional to chemical concentration.

Bleaching experiment by R. Danovaro and his team. They tested the effects of 100-μL sunscreens on Acropora divaricata nubbins after 24-hr incubation at various temperatures. (A) control; (B) nubbins incubated at 28°C; and (C) nubbins incubated (photo credit to R. Danovaro and his team)

In some parts of the world oxybenzone found on the surface has reached concentrations that indicate the potential for bioaccumulation of this chemical within reef organisms. Since oxybenzone mimics oestrogen it is causing male fish to change into females. This has been particularly noticed in turbot and sole feeding near sewage outlets. Since a healthy fish population is vital for reef survival this feminisation of fish will have a devastating long term impact.

As the effects of sunscreen are becoming more apparent positive action is being taken. In Mexico, several marine reserves have banned the use of none marine safe sun protection products after high mortality was noted in reef organisms and currently Hawaii is trying to ban the sale of harmful sunscreen. In addition, the development of eco-friendly sunscreens is now booming.

We at Gili Lankanfushi want to become part of this movement and understand that we need to protect our delicate marine environment, which is why the boutique is now selling a range of marine safe products, so next time you are here please help us protect our reef!

Support Sea grass

We all could do with reducing our carbon footprint and one easy way is to support local and global sea grass conservation initiatives.

Known as the lungs of the ocean, sea grass can produce 10 litres of oxygen per 1m2 everyday! Sea grass meadows are also a fantastic carbon sink as they sequester carbon dioxide from the water and this can slow the effects of ocean acidification created by global warming. This beautiful plant could be the key to stabilising the negative effects of climate change.

Yet despite this, 29% of global sea grass beds have already disappeared with 7% more being lost per year. In an attempt to address this issue, the Marine Biology team at Gili Lankanfushi is conducting a sea grass regrowth experiment. At the resort we have sea grass growing in shallow lagoons around the island and in a 10m2 area on the south east side of the island, we have been collecting data on how fast sea grass regrows after it has been removed.

The experiment has currently been running for six months, so it is too early to be accurate, but results currently show that 10% of the area has signs of regrowth. To date, we are only seeing shoots of a robust species of sea grass called E.acoroides. This is a species found in the tropics in water depth of one to three metres with light wave action.

Aerial view of Lankanfushi Island and sea grass beds

In the beds we find nursery fish, crustaceans, worms and sea cucumbers using the leaves as a nursery and haven against the current. We also often see resident green sea turtles feeding on sea grass as it is their primary diet and they consume 2kg per day!

Marine Biologists are very pro sea grass because sea grass beds stabilise sediment and reduce erosion by creating a network of roots. They also increase the water clarity and quality by soaking up nutrients or chemicals that run into the water. If given the choice, we would regenerate the meadows surrounding the island as with an increased meadow size, the resort would benefit from cleaner and clearer water and an increased population of nursery fish species and green sea turtles. By regenerating the full size of our sea grass meadows we would also offset some of our carbon footprint.

We have been in touch with sea grass specialists from Seagrass Watch and SeagrassSpotter and hope to work with these global conservation projects in the future. We have learnt from their wealth of experience that it takes around 3-4 years to naturally replenish a small sized, single species sea grass meadow and around 10 years to replenish a large sized multi-species meadow. If we helped regrowth by planting sea grass seeds, the areas would be replenished in around 2 years.

This brilliant plant could be the key to stabilising the negative effects of climate change. We hope resorts in the Maldives consider regenerating their sea grass beds to help offset their carbon footprint.

Do Your Part – Dive Against Debris®

Written by Megan Denny

For most people, ocean pollution is out of sight, out of mind, but as a dive professional you know that in many places there are significant debris problems lurking beneath the waves. That’s why Project AWARE® created Dive Against Debris® as a citizen science program that empowers you and your fellow divers to deliver critically needed data about the marine debris found in underwater habitats.

Since Dive Against Debris began in 2011:

  • More than 30,000 divers have participated
  • 900,000+ pieces of trash have been collected and reported
  • Thousands of entangled marine animals have been discovered

BeachNet2

The marine debris data reported by divers is essential to addressing and preventing ocean pollution. For example, last year, 26 percent of all debris items reported through Dive Against Debris was abandoned, lost or otherwise discarded fishing gear (ALDFG). ALDFG, also known as ghost gear, refers to derelict fishing gear that continues to capture fish and other marine animals long after it’s been lost or abandoned by fishermen). Ghost gear is devastating to marine habitats, entangling and killing hundreds of species including seals, turtles, dolphins and whales.  In a 2007 survey, NOAA estimated there are 85,000+ lobster and crab ghost traps in the Florida KeysNational Marine Sanctuary alone.

Through their Partnerships Against Trash, Project AWARE is committed to developing solutions with individuals, governments, NGOs and businesses including alliances such as the Global Ghost Gear Initiative (GGGI). Just this year, GGGI initiated ghost gear prevention and recovery programs in Alaska, Maine and the United Kingdom.

The ocean we love needs all hands on deck to protect it. By encouraging your student divers and customers to Dive Against Debris, we can improve the health of ocean ecosystems and provide valuable information about underwater debris to policy makers.

Reporting Marine Debris Just Got Easier

Project AWARE’s new Dive Against Debris app for Android and iOS makes it easy to report marine debris data. With the Dive Against Debris app you can:Open Water Manual (Redesign)

  • Quickly report debris by choosing from a list of common debris items
  • Easily add a dive site location using your mobile device’s GPS
  • Copy information from a previous submission at the same dive site.
  • No data connection? No problem. The app will store your data as a draft for you to complete and submit once connectivity is restored.

The free app is available for download after August 21 from the App Store or Google Play. Download it to report marine debris data and help spread the word.
