Madagascar in the context of Gulf Standard Time

Japan is an island country of 14,125 islands, of which approximately 260 are inhabited. Japan is the third-largest island country in the world, behind Indonesia and Madagascar. Japan is also the second-most-populous island country in the world, only behind Indonesia.

According to a survey conducted by the Japan Coast Guard in 1987, the number of islands in Japan was 6,852. At that time, the survey only counted islands with coastlines of 100 meters or more that were shown on paper maps.On February 28, 2023, the Geospatial Information Authority of Japan announced that the number of islands had been updated to 14,125 through a recount using digital maps. Since there is no international standard for counting islands, only islands with a coastline of 100 meters or more were counted, as in the past. According to the GSI, advances in surveying technology and the detailed representation of topographic features through digital mapping contributed to this announcement.

Determining the boundaries between the continents is generally a matter of geographical convention and consensus. Several slightly different conventions are in use. The number of continents is most commonly considered seven (in English-speaking countries) but may range as low as four when Afro-Eurasia and the Americas are both considered as single continents. An island can be considered to be associated with a given continent by either lying on the continent's adjacent continental shelf (e.g. Singapore, the British Isles) or being a part of a microcontinent on the same principal tectonic plate (e.g. Madagascar and Seychelles). An island can also be entirely oceanic while still being associated with a continent by geology (e.g. Bermuda, the Australian Indian Ocean Territories) or by common geopolitical convention (e.g. Ascension Island, the South Sandwich Islands). Another example is the grouping into Oceania of the Pacific Islands with Australia and Zealandia.

There are three overland boundaries subject to definition:

The following is a list of the 100 largest cities in Africa by urban population using the most recent official estimate. This reflects only cities located geographically in Africa including related islands.

The Austronesian people, sometimes referred to as Austronesian-speaking peoples, are a large group of peoples who have settled in Taiwan, maritime Southeast Asia, parts of mainland Southeast Asia, Micronesia, coastal New Guinea, Island Melanesia, Polynesia, and Madagascar that speak Austronesian languages. They also include indigenous ethnic minorities in Vietnam, Cambodia, Myanmar, Thailand, Hainan, the Comoros, and the Torres Strait Islands. The nations and territories predominantly populated by Austronesian-speaking peoples are sometimes known collectively as Austronesia.

The group originated from a prehistoric seaborne migration, known as the Austronesian expansion, from Taiwan, circa 3000 to 1500 BCE. Austronesians reached the Batanes Islands in the northernmost Philippines by around 2200 BCE. They used sails some time before 2000 BCE. In conjunction with their use of other maritime technologies (notably catamarans, outrigger boats, lashed-lug boats, and the crab claw sail), this enabled phases of rapid dispersal into the islands of the Indo-Pacific, culminating in the settlement of New Zealand c. 1250 CE. During the initial part of the migrations, they encountered and assimilated (or were assimilated by) the Paleolithic populations that had migrated earlier into Maritime Southeast Asia and New Guinea. They reached as far as Easter Island to the east, Madagascar to the west, and New Zealand to the south. At the furthest extent, they might have also reached the Americas.

Taiwanese indigenous peoples, formerly called Taiwanese aborigines, are the indigenous peoples of Taiwan, with the nationally recognized subgroups numbering about 600,303 or 3% of the island's population. This total is increased to more than 800,000 if the indigenous peoples of the plains in Taiwan are included, pending future official recognition. When including those of mixed ancestry, such a number is possibly more than a million. Academic research suggests that their ancestors have been living on Taiwan for approximately 15,000 years. A wide body of evidence suggests that the Taiwanese indigenous peoples had maintained regular trade networks with numerous regional cultures of Southeast Asia before Han Chinese settled on the island from the 17th century, at the behest of the Dutch colonial administration and later by successive governments towards the 20th century.

Taiwanese indigenous peoples are Austronesians, with linguistic, genetic and cultural ties to other Austronesian peoples. Taiwan is the origin and linguistic homeland of the oceanic Austronesian expansion, whose descendant groups today include the majority of the ethnic groups throughout many parts of East and Southeast Asia as well as Oceania and even Africa which includes Brunei, East Timor, Indonesia, Malaysia, Madagascar, Philippines, Micronesia, Island Melanesia and Polynesia.

In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material, and rises from the bed of a body of water close to the surface or above it, which poses a danger to navigation. Shoals are also known as sandbanks, sandbars, gravelbars, or bars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.

The term shoal is also used in a number of ways that can be either similar to, or quite different from, how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, the term refers to either any relatively shallow place in a stream, lake, sea, or other body of water; a rocky area on the seafloor within an area mapped for navigation purposes; or a growth of vegetation on the bottom of a deep lake, that occurs at any depth, or is used as a verb for the process of proceeding from a greater to a lesser depth of water.

The Blue Marble is a photograph of Earth taken on December 7, 1972, by Harrison Schmitt aboard the Apollo 17 spacecraft on its way to the Moon. Viewed from around 29,400 km (18,300 mi) from Earth's surface, a cropped and rotated version has become one of the most reproduced images in history.

In the original NASA image, named AS17-148-22727 and centered at about 26°19′49″S 37°25′13″E / 26.33028°S 37.42028°E / -26.33028; 37.42028 with the South Pole facing upwards, The Blue Marble shows Earth from the Mediterranean Sea to Antarctica. This was the first time the Apollo trajectory made it possible to photograph the south polar ice cap, despite the Southern Hemisphere being heavily covered in clouds. In addition to the Arabian Peninsula and Madagascar, almost the entire coastline of Africa and most of the Indian Ocean are clearly visible, a cyclone in the Indian Ocean is also visible, the South Asian mainland and Australia is on the eastern limb, and the eastern part of South America lies on the western limb.

The number of languages natively spoken in Africa is variously estimated (depending on the delineation of language vs. dialect) at between 1,250 and 2,100, and by some counts at over 3,000. Nigeria alone has over 500 languages (according to SIL Ethnologue), one of the greatest concentrations of linguistic diversity in the world. The languages of Africa belong to many distinct language families, among which the largest are:

• Niger–Congo, which include the large Atlantic-Congo and Bantu branches in West, Central, Southeast and Southern Africa.
• Afroasiatic languages are spread throughout Western Asia, North Africa, the Horn of Africa and parts of the Sahel.
• Saharan, Nilotic and Central Sudanic languages (grouped under the hypothetical Nilo-Saharan macro-family), are present in East Africa and Sahel.
• Austronesian languages are spoken in Madagascar and parts of the Comoros.
• Khoe–Kwadi languages are spoken mostly in Namibia and Botswana.
• Indo-European languages, while not indigenous to Africa, are spoken in South Africa and Namibia (Afrikaans, English, German) and are used as lingua francas in Liberia and the former colonies of the United Kingdom (English), former colonies of France and of Belgium (French), former colonies of Portugal (Portuguese), former colonies of Italy (Italian), former colonies of Spain (Spanish) and the current Spanish territories of Ceuta, Melilla and the Canary Islands and the current French territories of Mayotte and La Réunion.

There are several other small families and language isolates, as well as creoles and languages that have yet to be classified. In addition, Africa has a wide variety of sign languages, many of which are language isolates.

Seychelles (/seɪˈʃɛl(z)/ , /ˈseɪʃɛl(z)/; French: [sɛʃɛl] or [seʃɛl]), officially the Republic of Seychelles (French: République des Seychelles; Seychellois Creole: Repiblik Sesel), is an island country and archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is 1,500 kilometres (800 nautical miles) east of mainland Africa. Nearby island countries and territories include the Maldives, Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and the Chagos Archipelago to the east.Seychelles is the smallest country in Africa as well as the least populated sovereign African country, with an estimated population of 100,600 in 2022.

Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until it came under full British control in the early 19th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural society to a market-based diversified economy, characterised by service, public sector, and tourism activities. From 1976 to 2015, nominal GDP grew nearly 700%, and purchasing power parity nearly 1600%. Since the late 2010s, the government has taken steps to encourage foreign investment.

Mayotte (/maɪˈɒt/ my-OT; French: Mayotte, [majɔt] ; Shimaore: Maore, IPA: [maˈore]; Kibushi: Maori, IPA: [maˈori]), officially the Department of Mayotte (French: Département de Mayotte), is an overseas department and region and single territorial collectivity of France. It is one of the overseas departments of France as well as one of the 18 regions of France, with the same status as the departments of Metropolitan France. It is an outermost region of the European Union and, as an overseas department of France, part of the eurozone.

Mayotte is located in the northern part of the Mozambique Channel in the western Indian Ocean off the coast of Southeastern Africa, between the northwestern part of the island of Madagascar and northeastern Mozambique on the continent. Mayotte consists of a main island, Grande-Terre (or Maore), a smaller island, Petite-Terre (or Pamanzi), as well as several islets around these two. Mayotte's land area is 374 square kilometres (144 sq mi) and, with its 320,901 people according to January 2024 official estimates, is very densely populated at 858 inhabitants per km (2,228 per sq mi). The biggest city and prefecture is Mamoudzou on the larger Grande-Terre. The Dzaoudzi–Pamandzi International Airport is located on the neighbouring smaller island of Petite-Terre. The territory is also known as Maore, the native name of its main island.

The Common Market for Eastern and Southern Africa (COMESA) is a regional economic community in Africa with twenty-one member states stretching from Tunisia to Eswatini. COMESA was formed in December 1994, replacing a Preferential Trade Area which had existed since 1981. Nine of the member states formed a free trade area in 2000 (Djibouti, Egypt, Kenya, Madagascar, Malawi, Mauritius, Sudan, Zambia and Zimbabwe), with Rwanda and Burundi joining the FTA in 2004, the Comoros and Libya in 2006, Seychelles in 2009, Uganda in 2012 and Tunisia in 2018.

COMESA is one of the pillars of the African Economic Community.

Olea capensis, the black ironwood, is an African tree species in the olive family Oleaceae. It is widespread in sub-Saharan Africa: from the east in Somalia, Ethiopia and Sudan, south to the tip of South Africa, and west to Cameroon, Sierra Leone and the islands of the Gulf of Guinea, as well as Madagascar and the Comoros. It occurs in bush, littoral scrub and evergreen forest.

Other common names in English include ironwood, ironwood olive, East African olive and Elgon olive.

Cyperus papyrus, better known by the common names papyrus sedge, papyrus, paper reed, Indian matting plant, or Nile grass, is a species of aquatic flowering plant belonging to the sedge family Cyperaceae. It is a tender herbaceous perennial, forming tall stands of reed-like swamp vegetation in shallow water.

In nature, it grows in full sun, in flooded swamps, and on lake margins throughout Africa (where it is native), Madagascar, and the Mediterranean region. It has been introduced to tropical regions worldwide, such as the Indian subcontinent, South America, and the Caribbean.

Piracy is an act of robbery or criminal violence by ship or boat-borne attackers upon another ship or a coastal area, typically with the goal of stealing cargo and valuable goods, or taking hostages. Those who conduct acts of piracy are called pirates, and vessels used for piracy are called pirate ships. The earliest documented instances of piracy were in the 14th century BC, when the Sea Peoples, a group of ocean raiders, attacked the ships of the Aegean and Mediterranean civilisations. Narrow channels which funnel shipping into predictable routes have long created opportunities for piracy, as well as for privateering and commerce raiding.

Historic examples of such areas include the waters of Gibraltar, the Strait of Malacca, Madagascar, the Gulf of Aden, and the English Channel, whose geographic structures facilitated pirate attacks. The term piracy generally refers to maritime piracy, although the term has been generalized to refer to acts committed on land, in the air, on computer networks, and (in science fiction) outer space. Piracy usually excludes crimes committed by the perpetrator on their own vessel (e.g. theft), as well as privateering, which implies authorization by a state government.

The Rova of Antananarivo /ˈruːvə/ (Malagasy: Rovan'i Manjakamiadana [ˈruvᵊn manˌdzakəmiˈadə̥nᵊ]) is a royal palace complex (rova) in Madagascar that served as the home of the sovereigns of the Kingdom of Imerina in the 17th and 18th centuries, as well as of the rulers of the Kingdom of Madagascar in the 19th century. Its counterpart is the nearby fortified village of Ambohimanga, which served as the spiritual seat of the kingdom in contrast to the political significance of the Rova in the capital. Located in the central highland city of Antananarivo, the Rova occupies the highest point on Analamanga, formerly the highest of Antananarivo's many hills. Merina king Andrianjaka, who ruled Imerina from around 1610 until 1630, is believed to have captured Analamanga from a Vazimba king around 1610 or 1625 and erected the site's first fortified royal structure. Successive Merina kings continued to rule from the site until the fall of the monarchy in 1896, frequently restoring, modifying or adding royal structures within the compound to suit their needs.

Over time, the number of buildings within the site varied. Andrianjaka founded the Rova with three buildings and a dedicated tomb site in the early 17th century. The number of structures rose to approximately twenty during the late 18th-century reign of King Andrianampoinimerina. By the late 20th century, the Rova's structures had been reduced to eleven, representing various architectural styles and historical periods. The largest and most prominent of these was Manjakamiadana, also known as the "Queen's Palace" after Queen Ranavalona I, for whom the original wooden palace was built between 1839 and 1841 by Frenchman Jean Laborde. In 1867 the palace was encased in stone for Queen Ranavalona II by Scotsman James Cameron, an artisan missionary of the London Missionary Society. The neighbouring Tranovola, a smaller wooden palace constructed in 1819 by Creole trader Louis Gros for King Radama I, was the first multi-story building with verandas in the Rova. The model offered by Tranovola transformed architecture throughout the highlands over the course of the 19th century, inspiring a widespread shift toward two-storey houses with verandas. The Rova grounds also contained a cross-shaped wooden house (Manampisoa) built as the private residence of Queen Rasoherina, a stone Protestant chapel (Fiangonana), nine royal tombs, and a number of named wooden houses built in the traditional style reserved for the andriana (nobles) in Imerina. Among the most significant of these were Besakana, erected in the early 17th century by Andrianjaka and considered the throne of the kingdom, and Mahitsielafanjaka, a later building which came to represent the seat of ancestral spiritual authority at the Rova.

Antananarivo (Malagasy: [antananaˈrivʷ]; French: Tananarive, pronounced [tananaʁiv]), also known by its colonial shorthand form Tana (pronounced [tana]), is the capital and largest city of Madagascar. The administrative area of the city, known as Antananarivo-Renivohitra ("Antananarivo-Mother Hill" or "Antananarivo-Capital"), is the capital of Analamanga region. The city sits at 1,280 m (4,199 ft) above sea level in the center of the island, making it the highest national capital by elevation among the island countries. It has been the country's largest population center since at least the 18th century. The Presidency, National Assembly, Senate, and Supreme Court are located there, as are 21 diplomatic missions and the headquarters of many national and international businesses and non-governmental organizations. It has more universities, nightclubs, art venues, and medical services than any city on the island. Several national and local sports teams, including the championship-winning national rugby team, the Makis, are based here.

Antananarivo was historically the capital of the Merina people, who continue to form the majority of the city's 1,274,225 (2018 census) inhabitants. The surrounding urban areas have a total metropolitan population approaching three million. All eighteen Malagasy ethnic groups, as well as residents of Chinese, Indian, European, and other origins, are represented in the city. It was founded circa 1610, when the Merina King Andrianjaka (1612–1630) expelled the Vazimba inhabitants of the village of Analamanga. Declaring it the site of his capital, Andrianjaka built a rova (fortified royal dwelling) that expanded to become the royal palaces of the Kingdom of Imerina. The city retained the name Analamanga until the reign of King Andriamasinavalona (1675–1710), who renamed it Antananarivo ("City of the Thousand") in honor of Andrianjaka's soldiers.

The spice trade involved historical civilizations in Asia, Northeast Africa and Europe. Spices, such as cinnamon, cassia, cardamom, ginger, pepper, nutmeg, star anise, clove, and turmeric, were known and used in antiquity and traded in the Eastern World. These spices found their way into the Near East before the beginning of the Christian era, with fantastic tales hiding their true sources.

The maritime aspect of the trade was dominated by the Austronesian peoples in Southeast Asia, namely the ancient Indonesian sailors who established routes from Southeast Asia to Sri Lanka and India (and later China) by 1500 BC. These goods were then transported by land toward the Mediterranean and the Greco-Roman world via the incense route and the Roman–India routes by Indian and Persian traders. The Austronesian maritime trade lanes later expanded into the Middle East and eastern Africa by the 1st millennium AD, resulting in the Austronesian colonization of Madagascar.
