Status of Coral Reefs of the World: 2002 Status of Coral Reefs of the World: 2002 Edited by Clive Wilkinson PDF compression, OCR, web optimization using a watermarked evaluation copy of CVISION PDFCompressor Dedication This book is dedicated to all those people who are working to conserve the coral reefs of the world – we thank them for their efforts. It is also dedicated to the International Coral Reef Initiative and partners, one of which is the Government of the United States of America operating through the US Coral Reef Task Force. Of particular mention is the support to the GCRMN from the US Department of State and the US National Oceanographic and Atmospheric Administration. I wish to make a special dedication to Robert (Bob) E. Johannes (1936-2002) who has spent over 40 years working on coral reefs, especially linking the scientists who research and monitor reefs with the millions of people who live on and beside these resources and often depend for their lives from them. Bob had a rare gift of understanding both sides and advocated a partnership of traditional and modern management for reef conservation. We will miss you Bob!

The Philippines and Sweden have combined to guide the Secretariat of the International Coral Reef Initiative (ICRI) with the goal of bringing developing and developed countries together to conserve coral reefs. Our coral reefs are being damaged by both natural and human pressures and unless we act now, it is predicted that over half of the world’s coral reefs could be severely degraded within a generation. Coral reefs can recover from natural threats, but recovery is slow from the direct and indirect damage that people are doing to reefs. Often that damage is inadvertent as people seek food or cultural items from the reefs, but unfortunately some of the damage is deliberate through constructing airports, ports and dredging channels. Damage is caused indirectly through poor land use practices that result in sediments and excess nutrients pouring over the reefs and through the release of sewage and industrial wastes that cause eutrophication. Even our excessive use of plastic bags ends up damaging coral reefs. The responses to these alarm calls have been the establishment of ICRI, the Global Coral Reef Monitoring Network, CORDIO (Coral Degradation in the Indian Ocean), Reef Check, ReefBase and the World Resources Institute Reefs at Risk project, to mention just some. All people in the world are ‘stakeholders’ in coral reefs as we have inherited their wealth of biodiversity and natural beauty, therefore we all share the responsibility for conserving them. We now understand what damages coral reefs and the critical measures that users, local and national governments, international agencies and NGOs have to do in partnership to conserve reefs. We are pleased to see that in the Status of Coral Reefs of the World: 2002 report, there are many global and local initiatives being implemented to arrest the damage, conserve coral reefs and establish more protected areas. One example is Apo Island, in the Philippines, where the local university and the community have worked together to conserve their resources for the benefit of all. Another initiative is to ensure that the trade in live fish for restaurants and the aquarium trade is ecologically sustainable, and not damaging the reefs of Southeast Asia and the Pacific. The Government of the Philippines, one of the founding countries of ICRI, hosted in 1995 the first ICRI international workshop in Dumaguete City, which outlined the pioneering global strategy for coral reefs through the ICRI Call to Action and Framework for Action. In March 2003, the Philippines will host the 2nd International Tropical Marine Ecosystem Management Symposium (ITMEMS 2) in Manila. It is expected to become another PDF compression, OCR, web optimization using a watermarked evaluation copy of CVISION PDFCompressoriii Status of Coral Reefs of the World: 2002 milestone conference to identify strategies on coral reef and associated ecosystems management when strong resolve is needed to respond to the WSSD Plan of Implementation. Then and now, the Philippines continues to be instrumental in bringing forth strategies and actions for implementation at global and national levels. A significant Philippines national strategy is the devolution of ecological management responsibility to the municipality and ‘barangay’ level under the Local Government Code passed by Congress in 1991. The case studies on Pages 127, 143, 146 and 148 illustrate that when communities are given the responsibility for managing their own resources with help from government and scientists, the damage to the reefs can be reversed. In addition, the Philippine Government has been proud to declare the large Tubbataha National Marine Park as a World Heritage Site. It is jointly managed by the Palawan Council for Sustainable Development and the World Wide Fund for Nature (WWF) Philippines. In March 2002, as President of the Philippines, I had the wonderful opportunity to dive at Tubbataha, which enabled me to experience the natural beauty of Palawan. Even more rewarding is the genuine concern that the Filipinos have for conserving and managing these reefs. The same tourism potential can be developed in other Philippine reef areas. We must start increasing the awareness of our people about how they can conserve and benefit from reef resources. We expect that the recommendations and assistance from the Symposium will greatly contribute to our efforts. Sweden, also one of the founding countries of ICRI when it first met in 1994, has continued as an active member since then. In 2001 and 2002, Sweden together with the Philippines, served as Secretariat of ICRI. Sweden has also supported coral reef-related activities in the Indian Ocean region through the CORDIO Program (Coral Reef Degradation in the Indian Ocean; Page 363). The program was initiated when the major coral bleaching and mortality event of 1998 struck reefs in East Africa, the Maldives, the Seychelles, Comoros and Sri Lanka. As Prime Minister of Sweden, I am proud of the pro- active initiatives that our government has launched to assist countries with the sustainable development of coral reefs. We are pleased to endorse this report and hope that it will stimulate international efforts to conserve coral reefs. We need action at all levels, from assisting local communities with co-management agreements, to truly global initiatives like managing the trade in coral reef products and reducing the release of greenhouse gases which apparently are linked to coral bleaching. We need to conserve coral reefs because of their magnificent resources of biodiversity, unparalleled beauty and enormous tourism potential, and particularly because sustainably managed reefs can provide food and shoreline protection for hundreds of millions of people around the world.

    Welcome to CHUUK A Guide to the Historic Wrecks Courtesy Chuuk and Visitors Bureau Island Attractions - Best Wrecks - Island Maps - Activities - History Welcome he many islands within this huge atoll are crowned with Tnatural beauty. The outer barrier reef is punctuated with idyllic sandspits dotted with coconut palms. The high islands in the central lagoon rise into the blue Micronesian skies. The word “Chuuk” means “high mountains” in the Chuukese language. Chuuk State, which is one of four states in the Federated States of Micronesia, consists of 290 islands with 250 islands uninhabited. The islands have natural beauty and most still display a traditional lifestyle. The main population area is within the vast Chuuk Lagoon (sometimes called Truk Lagoon) where the vestiges of WWII attract divers from around the world. The huge inner lagoon is famously known for the “World’s Greatest Wreck Diving.” The islands were heavily attacked by the US in the Second World War then bypassed and blockaded by the Allies. The sunken hulls of Japanese ships remain along with ruined weapons and fortifications on land. Many divers feel it has the best collection of shipwrecks and WWII era airplanes in the world. The hulks have been transformed into amazing “shipreefs”, holding the very best of the undersea world and maritime history at one site. Incredible corals in a kaleidoscope of colors and shapes fed by warm, clear waters attract divers worldwide. The reefs also are home to a great variety of fish and corals. Visitors can see the islands and there are many “picnic islands” that are great for day trips and relaxing.

    Final Report CORAL REEF COMMUNITIES FROM NATURAL RESERVES IN PUERTO RICO : a quantitative baseline assessment for prospective monitoring programs Volume 2 : Cabo Rojo, La Parguera, Isla Desecheo, Isla de Mona by : Jorge (Reni) García-Sais Roberto L. Castro Jorge Sabater Clavell Milton Carlo Reef Surveys P. O. Box 3015, Lajas, P. R. 00667 [email protected] Final report submitted to the U. S. Coral Reef Initiative (CRI-NOAA) and DNER August, 2001 i PREFACE A baseline quantitative assessment of coral reef communities in Natural Reserves is one of the priorities of the U. S. Coral Reef Initiative Program (NOAA) for Puerto Rico. This work is intended to serve as the framework of a prospective research program in which the ecological health of these valuable marine ecosystems can be monitored. An expanded and more specialized research program should progressively construct a far more comprehensive characterization of the reef communities than what this initial work provides. It is intended that the better understanding of reef communities and the available scientific data made available through this research can be applied towards management programs designed at the protection of coral reefs and associated fisheries in Puerto Rico and the Caribbean. More likely, this is not going to happen without a bold public awareness program running parallel to the basic scientific effort. Thus, the content of this document is simplified enough as to allow application into public outreach and education programs. This is the second of three volumes providing quantitative baseline characterizations of coral reefs from Natural Reserves in Puerto Rico.

McGinty 2012 All Rights Reserved ACKNOWLEDGEMENTS A great many people have helped me reach this point, and I am so grateful for their kindness, generosity and, above all else, patience. My committee, Laura Mydlarz, Robert McMahon, Laura Gough, James Grover and Sophia Passy have been instrumental with their advice and guidance. Linda Taylor, Gloria Burlingham, Paulette Batten and Sherri Echols have made the often baffling maze of graduate school policies and protocols infinitely easier, and Ray Jones and Melissa Muenzler were an amazing resource in some of my most trying moments with technical equipment. My labmates through the years, Laura Hunt, Jorge Pinzón, Caroline Palmer, Jenna Pieczonka, and especially Whitney Mann, have been instrumental with their guidance, brainstorming, and research assistance. My friends and colleagues are too numerous to name, but the advice, support, cheery distractions and commiseration of Corey Rolke, Matt Steffenson, Claudia Marquez Jayme Walton, Michelle Green, Matt Mosely, and James Pharr have all been a crucial part of my success. The blood, sweat and tears we have shed together will bind this dissertation and remain strong in my memory long after the joys and pains we’ve faced have faded into a fuzzier version of reality. Finally, my family deserves much of the credit for where I am today.

  • DRAFT Sustainable Tourism for Marine Recreation Providers
    DRAFT Sustainable Tourism for Marine Recreation Providers Wolcott Henry photo The Coral Reef Alliance: Coral Parks Program Education Series ©2004 Sustainable Tourism Introduction In this era of the global economy, tourism has become a primary source of revenue for many regions of the world, generating nearly $500 billion in worldwide revenues in 2001, and continuing to grow (WTO, 2001). The United Nations Environment Program (UNEP) facilitated a study that points out that the tourism industry now represents more than 10% of the world’s gross domestic product (UNEP, 2002). While tourism brings significant benefits for both local and global economies, its rapid growth and development in recent decades has caused widespread social and environmental change across the globe, particularly in popular coastal resort destinations. In contrast, the concept of sustainable tourism is now seen as a way to promote socio-economic development in a given region while simultaneously protecting local culture and the natural environment. In order to address these issues and how they impact coral reefs, the Coral Reef Alliance (CORAL) has compiled this Sustainable Tourism for Marine Recreation Providers handbook. In an effort to promote sustainable tourism, the information contained in this handbook highlights some of the current environmental problems associated with tourism growth and development, and promotes practical solutions for marine recreation providers to adopt good environmental practices. We encourage readers to provide us with feedback as to how we can improve this publication.

Lecturer at Faculty of Fisheries and Marine Science, UNSRAT, Manado 2 Professor at Faculty of Fisheries and marine Science, Brawijaya University, Malang 3 Professor at Faculty of Agriculture, Brawijaya University, Malang Abstract: This study was aimed at knowing and analyzing the fishermen’s household characteristics in Bunaken National Park. It used survey method through structured interviews in order to obtain primary data of the fisheries business owner’s and boat crew’s households. The secondary ones were also collected from the office of Marine and Fisheries Services at the provincial, regency, and municipality levels for 2006 – 2010, Fishermen’s household sampling was carried out with cluster and multi stage random sampling. Results showed that fishing, post-harvest and non-fisheries activities of the owner’s household per working period were higher than those of the boat crews. In contrast, the working opportunity of the owner’s household in fishing, post- harvest, and non-fisheries was lower than that of crew’s household. The average income from fishing, post- harvest, and non-fisheries for the owner’s household was higher than that of the crew’s household. Based on the average number of the owner’s households as many as 3.5 people and of the crew’s as many as 3 people, the income per capita was IDR 14.365 million/year or an average of IDR.
