Activities including education, regulation an d the insane asylum of marine protected realms help protect these reefs.Ind wizsiaIndonesia is root to one third of the worlds corals covering nearly 85,000 determine kilometres (33,000 sq mi) and one quarter of its fish species. Indonesias coral reefs are placed in the heart of the Coral Triangle and submit fallen victim to destructive fishing, tourism and bleaching. Data from 414 reef monitoring stations in 2000 found that moreover 6% are in excellent condition, speckle 24% are in inviol suitable condition, and approximately 70% are in poor to fair condition.50FilipinosIn 2007, Reef Check, the worlds largest reef conservation organization, recited that only 5% of Philippines 27,000 square kilometres (10,000 sq mi) of coral reef are in excellent condition Tubbataha Reef, Marine Park in Pa honoran, Apo Island in Negros Oriental, Apo Reef in Puerto Galera, Mindoro, andVerde Island Passage off Batangas. Philippine coral reefs is Asias second largest.51 chinawareCoral reefs in Taiwan are being threatened by human population growth. many corals are affected by untreated sewage and souvenir-hunting holiday pay offrs, not penetrating that this practice destroys habitat and causes illness. Many corals find turned black from dioceanse off Taiwans southeast coast.52-IndonesiaIndonesia has 2,915,000 square kilometers of marine area. The reef area is 51,020 square kilometers. Of that amount, 82% of it is at risk. Indonesia holds 17% of the worlds total coral reef areas. Blast fishing, which has been illegal since 1985 still goes on today, along with cyanide fishing (1995). Another factor that is hurting the coral reefs in Indonesia is the amount of coral that they export. They are the worlds largest exporter of corals, business deal about 500 tons of coral per year.16 COREMAP is constituent Indonesia with their destruction of corals by working in 9 of the 32 provinces. They want to 1. Heighten law enforcement to protect coral reefs2. Establish coral reef monitoring and learning systems, in high society to conduct research on the status of coral reefs and more effectively disseminate that information to stakeholder groups 3. Develop confederacy-based circumspection systems and profit public participation in coral reef resource forethought 4. Increase institutional capacity and strengthen inter-institutional coordination in planning and implementing policy that affects coral reef arrangement, and 5. Enhance public knowledge of the importance of coral reef and motivate people to actively participate in the management and induceable use of coral reefs.PhilippinesThe Philippines, with more than 7,000 islands and warm ocean waters, skirt about 26,000 square kilometers of coral reef. 3 These coral reefs have upstartly brought the oversight of beneficial scotch uses to the Philippines governing.4Benefits of Coral Reefs in Philippines1. Coral reefs break the waves from the chance of eroding the coastline of the islands 5 2. Protection of Communities the reefs act as buffer zones meaning they reduction the power of typhoons and hurricanes as they approach the Philippine Islands 6 3. Economic Benefits Fishing off the coral reefs, profits from tourism, for example, Diving tours and snorkeling areas on the shal broken reefs. These economic benefits create many unseasoned jobs and profitable opportunities to the country.StateFor the past 50 eld, the pro ascribe of degraded reefs in Indonesia ontogenesisd from 10 to 50%. From 1989 to 2000 reefs with over 50% stick out coral cover declined from 36 to 29%. western Indonesia, which is more developed and holds the majority of the nations population, faces the greatest threats to its coral reefs. Surveys concluded that reef condition improves from west to east. The partage of reefs in good or excellent condition (live coral cover of 50% or more) is 23% in western Indonesia versus 45% in eastern Indonesia. 65% of written reports taken from the Maluku islan ds had evidence of bomb vilify. In addition, reefs affected by land-based pollution (i.e. sediment discharge into reefs by deforestation, industry, sewage, and fertilizer) show 30-50% less diversity at depths of three meters and 40-60% less diversity at 10 meters in equation to pristine reefs. The 1997-1998 el Nino raset triggered wide deal bleaching in Indonesia, with western and western Indonesia most affected.Bleaching was recorded in East Sumatra, Java, Bali, and Lombok. In the Seribu Islands northwest of Jakarta, 90-95% of coral reef from the reef flat down to 25 meters died. dickens years later, the Seribu Islands significantly recovered, with live coral cover of 20-30% (2000). Coral reefs in Indonesia are located near Java (Batavia), Nusa Dua, Jakarta and Saribu. 8 30% of the Philippines coral reefs are dead while 39% are demise. The watchword isnt all bad Establishment of the Sumilon Island marine reserve has resulted in a marked comeback of fish in adjacent areas. on with the establishment of the Sumilon Island marine reserve, at that place is hope for the Philippines via boosts in ecotourism. In recent years, local anaesthetic Filipino governments have discovered that fishing is not the only economic benefit the reefs can provide.They are confident that with a spread of ecotourism, even local fishermen willing reap the financial benefits of this economic sector. A surge in coral reef conservation education is helping the tourism sector provide information to tourists on how to preserve the coral reefs while they enjoy the beauty and serenity of the reefs.17The Philippines ecotourism sector is unfortunately conquer at this time cod to a limited budget and there are approximately 7,000 islands to patrol for destructive fishing techniques.8 9. Destructive fishing techniques are thought to be the largest contributor to reef degradation in the Philippines. The first ever mass-bleaching event in the Philippines was reported in 1998-99. It be gan at Batangas, off Luzon, in June 1998 and then proceeded nearly clockwise more or less the Philippines, correlating with foolish sea-surface temperatures.Most reefs of northern Luzon, west Palawan, the Visayas, and parts of Mindanao were affected. Subsequent mortalities were highly variable, with decreases in live coral cover ranging from 0.7 to 46 share and up to 80 percentage in Bolinao. Recent surveys in 1997 found a low percentage of reefs to be in excellent condition. They found only 4 percent of Philippine reefs in excellent condition (i.e., over 75 percent hard or soft coral cover), 28 percent in good condition (50-75 percent coral cover), 42 percent in fair condition (25-50 percent coral cover), and 27 percent in poor condition (less than 25 percent coral cover). The Visayas have experienced the most significant decline in coral cover, exhibiting an sightly of only 11 percent hard coral cover. 10 A involve in the early 90s revealed that coral reefs are alter by a v ariety of human activities such as folk sewage, industrial waste, and agri heathenish chemicals from land that are washed to the sea. 11This was a new finding for the time period in which it was widely believed that the main damage to coral reefs was causes by oil spills or from pollution dumped by ships. This survey was concentrated on SE Asia mainly because it was believed that coral reefs in this office were at great threat of extinction if continued to be unmanaged. In the last thirty years climate change has had the most unwholesome effect on corals. (Hughes) Currently one of the major issues the Indonesian government is dealing with is climate change. (CIA knowledge domainfactbook) When the ocean warms such as in El Nino, coral bleaching occurs, which kills the coral. (Hughes) The reefs are incredibly important to the economy and people of Southeast Asia.The reefs bring in $1.6 billion a year through fishing, employment, and the tourist industry. (Reefs at Risk in Southeas t Asia Key Findings 2002) Today, the coral reefs located in the Philippines and Indonesia are in great danger. Fishermen are constantly practising bread and butter-threatening methods such as blast fishing and dynamite fishing. These practices prove to be detrimental to the coral reefs as well as the marine life in the surrounding areas. Because of the dangerous methods, fish that are usually near the coral reefs are no long-term there any more. Two of these fish are Groupers and snappers. According to David Nockels it was only seven years ago that 30% of the reefs were dead in this region and many more were dyingMarine protected areasAmongst the many proposed solutions to the problems plaguing coral reefs in Southeast Asia is the intromission of marine protected areas (MPAs). Currently marine protected areas make up around 8% of the area of Southeast Asian coral reefs.26 The World Commission on Protected Areas 12, amongst other groups, has been active in establishing MPAs in S outheast Asia. However, the success rate of MPAs in Southeast Asia is low, with an estimated 14% of MPAs rated effectively managed.30 13 This rate reflects the difficulty of implementing MPAs. Moreover, it shows that much work is still needed to make MPAs successful in Southeast Asia. IUCN has defined an MPA as any area of intertidal or subtidal terrain, unitedly with its overlying water and associated flora, fauna, historical and cultural features, which has been reserved by law or other effective marrow to protect part or all of the enclosed environment.31In other words, an MPA is a marine area in which the water pillar and all the life that exists in it are protected through laws. These laws intimidate certain practices at heart the MPA, which can differ per MPA. Marine protected areas, in sum, provide a marine mental institution which can foster an increase in marine biodiversity.32 (See also 14). This increased biodiversity is though to be able to carry over to the non-p rotected surrounding areas in which fishing can take place. This is important for a number of reasons. In the Southeast Asian context, specially amongst the islands of the Philippines and Indonesia, the sea and people are very much interconnected. As mentioned, the sea provides both a source of income and source of food for the people. In the Philippines, for example, 67% of protein food consumption comes from fish and fish products. Additionally, roughly one one thousand million people in the Philippines are employed in the fishing industry.33increase fish stocks resulting from marine protected areas only add to the solutions needed to revitalise Southeast Asian economies, life systems, and coral reefs. In addition, the LMMA (Locally-Managed Marine Area) net is another organization that takes part in the Southeast Asia marine conservation. akin(predicate) to the MPA, the LMMA also provides protection areas in the sea. However, according to the definition above, an LMMA is an e xample of an MPA because an MPA includes a large space within and close by the area. The LMMA involves members from around the world, and the communities within the managed areas. The goal of LMMA is to allow members and local communities to learn the uses of protected resources.15 Due to the broad destruction of coral reefs in Southeast Asia, the LMMA has established two areas in Eastern Indonesia Padaido Islands, Biak, West Papua, and Southern Ambon Island and the Moluccas Islands and various areas in the Philippines.With the help of the LMMAs, the local communities would learn to preserve their marine goods, and be able to maintain for longer years. Gradually, the communities will accommodate bigger and healthier fish. 16 There are an estimated cd MPAs in the Philippines. Of the 400 only 16% have yielded an increase in bio-diversity. The high failure rate is due to poor management and a lack of regulation.34Despite the numerous failures there have been successes. One of the bes t cognise areas is Apo island where a small community has effectively managed an MPA since the mid 1980s. The Apo MPA includes a censor on detrimental fishing practices and a no-take zone covering 10% of their reef. Apos reef has thrived giving hope to Philippine reefs.35Contributions for managementThe state of the coral reefs in the Philippines and Indonesia are depleting with every blink of an eye. It is to no ones surprise that the Philippines have lost more than 80% since the 1920s. In Indonesia it is a little better due to the some drastic actions make by the government. On December 6, 2002 the Asian Development Bank (ADB) okay a US$33 million bestow in order to save what is the rest of these important organisms. Over fishing, illegal fishing methods, and overpopulation have all contributed to the decline of the coral reefs both in the Philippines and Indonesia. Along with the loan the Coral Reef Rehabilitation and Management Project (Phase II), the second part of a three p hase plan has given us all hope in restoring coral reefs in this part of the region. The Ministry of Marine personal matters and Fisheries will oversee the whole entire project with a due date of June 30, 2009. If it all goes according to plan the fishing industry will be the benefited the most.However, government action is not always necessary to manage reefs. When the community dependent on the resources provided by coral works together to save and restore the fish population, the results can be very good. The community managed reefs of Apo Island, located in the southern Philippines, known worldwide for its success. The waters around Apo Island are home to about 650 species of fish and 400 species of corals. The waters of Apo Island were not always this full of life. Fishing is the major occupation on the island, and even those who do not fish, rely on the catch for their protein. So when a fishermans catch began shortening, later years of unregulated fishing, it was very easy for them to resort to destructive methods of fishing,such as blast fishing and cyanide fishing, to get by.These methods almost led to the end of the already dwindling fish stocks. The community began, through education and widespread involvement, the process of making these practices socially unacceptable.36 People began patrolling the waters in a small area with the inclination of allowing fish to flourish and repopulate and then spill over into areas that had been fished out. This informal establishment of a sanctuary was first met with a lot of resistance, eventually though, after seeing the obvious improvements, the island community and local council were able to formalize the sanctuary in 1985, three years after it started. This formalization extended the sanctuary to water surrounding the island up to 500 meters from the shore and declaring a portion a no-take fish sanctuary.37To manage the coral reefs effectively to preserve what is left over(p) of the beautiful natural res ource, individual people must unite. If the marine ornamentals trade is to successfully turn around and begin to sustain more live fish, certain people must perform their jobs to the fullest. Firstly, there if lobbyists are responsible for(p) about the issue, they will provide healthy animals, maintain healthy reefs, sustain reef animal populations, and adequately compensate fishing communities for their efforts. Also, responsible industry operators must minimize animal mortality and habitat impacts and focus on animal health and quality collection practices. The problem with this method, though, is that merely cuss and word of mouth arent enough. If we are to legitimately depleting the coral reefs in Southeast Asia, we must set international standards.
