The Primeiras and Segundas Archipelago is a chain of 10 sparsely inhabited barrier islands and two coral reef complexes situated in the Indian Ocean off the coast of the Zambezia Province of Mozambique. The islands lie in two groups along the western side of the Mozambique Channel with the Segundas Islands located near the coastal city of Angoche.
The islands lie in a string along Africa's continental shelf. The five Segundas islands are in the north, separated by a stretch of open water and reefs from the five islands of the Primeiras chain to the south. The eastern sides of the islands are fringed with coral reefs, composed mainly of soft corals, with hard corals at their southern edges. Beds of seagrass are situated between the islands and the mainland, which are important habitats for sea turtles and dugongs. The southern islands support Mozambique's largest nesting grounds for green sea turtles. Hawksbill sea turtles and Olive ridley sea turtles use the islands to forage for food on the reefs. The archipelago also hosts the most important dugong population in the western Indian Ocean. [1]
Vegetation on these low islands includes mangrove, grass and scrub. Offshore, they are more noted for the biodiversity of their spectacular coral reefs, which support an important fishery. [2] Due to the lack of reliable sources of fresh water, habitation on the islands is sparse — mainly in support of fishing operations.
Ilha do Fogo, the second island from the south in the archipelago, currently has the only infrastructure in the Primeiras Islands and runs on solar power. It is set up as SCUBA retreat for small groups of guests. [3]
The European discovery of the archipelago came on 25 February 1498 during Vasco da Gama's first expedition to India. [4] The islands became an important stopping-off point for Portuguese trading fleets sailing for India and the Orient, which were often in need of emergency repairs after rounding the Cape of Good Hope. [5] [6] The islands remained a colony of Portugal until Mozambican independence in 1975, at which time they became part of Mozambique.

The area has been threatened by illegal fishing operations and impacts from unauthorized tourism. Cutting down of coastal mangrove has also increased erosion, with negative effects on marine life. The archipelago was the focus of joint conservation and development projects by CARE and the World Wildlife Fund in cooperation with the government of Mozambique and local NGOs between 2008 and 2018. These projects were aimed at preserving the environment and surrounding coral reef system, restoring fisheries, protecting breeding grounds for sooty terns, dugongs and green sea turtles, and creating a better quality of life for the people of the region.
The initial goal of the projects was the creation of a 17,000 km2 area to be protected as a marine reserve. [7] This was realized in 2012 when Mozambique established Africa's largest protected marine zone surrounding the islands. [8] Although the joint project has ceased their activities, there is a continuing goal is to increase awareness among local people of how their activities affect the larger environment and their own long-term security and prosperity through the efforts of Fire Island Conservation [9] and other NPOs. Moving towards more sustainable farming and fishing methods is also a focus of educational outreach to area communities. [10] [11] [12]

The Philippine Sea is a marginal sea of the Western Pacific Ocean east of the Philippine Archipelago and the largest sea in the world, occupying an estimated surface area of 5 million square kilometers. The Philippine Sea Plate forms the floor of the sea. Its western border is the first island chain to the west, comprising the Ryukyu Islands in the northwest and Taiwan in the west. Its southwestern border comprises the Philippine islands of Luzon, Catanduanes, Samar, Leyte, and Mindanao. Its northern border comprises the Japanese islands of Honshu, Shikoku and Kyūshū. Its eastern border is the second island chain to the east, comprising the Bonin Islands and Iwo Jima in the northeast, the Mariana Islands in the due east, and Halmahera, Palau, Yap and Ulithi in the southeast. Its southern border is Indonesia's Morotai Island.
The Gulf of Mannar is a large shallow bay forming part of the Laccadive Sea in the Indian Ocean with an average depth of 5.8 m (19 ft). It lies between the southeastern tip of India and the west coast of Sri Lanka, in the Coromandel Coast region. The chain of low islands and reefs known as Adam’s Bridge or Rama Setu, which includes Mannar Island, separates the Gulf of Mannar from Palk Bay, which lies to the north between India and Sri Lanka. The estuaries of Thamirabarani River and Vaippar River of South India and the Malvathu Oya of Sri Lanka drain into the Gulf. The dugong is found here.
The Bazaruto Archipelago is a group of six islands in Mozambique, near the mainland city of Vilankulo. It comprises the islands of Bazaruto, Benguerra, Magaruque, Banque, Santa Carolina and Shell. Nyati Island is located further south.
The Coral Triangle (CT) is a roughly triangular area in the tropical waters around the Philippines, Indonesia, Malaysia, Papua New Guinea, the Solomon Islands and Timor-Leste. This area contains at least 500 species of reef-building corals in each ecoregion. The Coral Triangle is located between the Pacific and Indian oceans and encompasses portions of two biogeographic regions: the Indonesian-Philippines Region, and the Far Southwestern Pacific Region. As one of eight major coral reef zones in the world, the Coral Triangle is recognized as a global centre of marine biodiversity and a global priority for conservation. Its biological resources make it a global hotspot of marine biodiversity. Known as the "Amazon of the seas", it covers 5.7 million square kilometres (2,200,000 sq mi) of ocean waters. It contains more than 76% of the world's shallow-water reef-building coral species, 37% of its reef fish species, 50% of its razor clam species, six out of seven of the world's sea turtle species, and the world's largest mangrove forest. In 2014, the Asian Development Bank (ADB) reported that the gross domestic product of the marine ecosystem in the Coral Triangle is roughly $1.2 trillion per year and provides food to over 120 million people. According to the Coral Triangle Knowledge Network, the region annually brings in about $3 billion in foreign exchange income from fisheries exports, and another $3 billion from coastal tourism revenues.

The Menai Bay Conservation Area (MBCA) is located in Menai Bay, Zanzibar Tanzania. At 470 square kilometres (180 sq mi), it is Zanzibar's largest marine protected area. It was officially established as a conservation area in August 1997 in the traditional fishing area, known as Unguja Island, covering the tropical marine environment comprising extensive coral reefs, tropical fish, sea grasses, and mangrove forests. In addition to controlling illegal fishing, MBCA's alternative initiatives have included bee keeping, mangrove replanting, tree nurseries and tourism. The management of the MBCA falls upon the Fisheries Department and the bay's local villages. It is rated by the IUCN as Category VI Managed Resource Protected Area.
