Guinea in the context of Paleotropics

West Africa, also known as Western Africa, is the westernmost region of Africa. The United Nations defines Western Africa as the 16 countries of Benin, Burkina Faso, Cape Verde, The Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra Leone, and Togo, as well as Saint Helena, Ascension and Tristan da Cunha (a United Kingdom Overseas Territory). As of 2021, the population of West Africa is estimated at 419 million, and approximately 382 million in 2017, of which 189.7 million were female and 192.3 million male. The region is one of the fastest growing in Africa, both demographically and economically.

Historically, West Africa was home to several powerful states and empires that controlled regional trade routes, including the Mali and Gao Empires. Positioned at a crossroads of trade between North Africa and sub-Saharan Africa, the region supplied goods such as gold, ivory, and advanced iron-working. During European exploration, local economies were incorporated into the Atlantic slave trade, which expanded existing systems of slavery. Even after the end of the slave trade in the early 19th century, colonial powers — especially France and Britain — continued to exploit the region through colonial relationships. For example, they continued exporting extractive goods like cocoa, coffee, tropical timber, and mineral resources. Since gaining independence, several West African nations, such as the Ivory Coast, Ghana, Nigeria and Senegal — have taken active roles in regional and global economies.

Liberia, officially the Republic of Liberia, is a country on the West African coast. It is bordered by Sierra Leone to its northwest, Guinea to its north, Ivory Coast to its east, and the Atlantic Ocean to its south and southwest. It has a population of around 5.5 million and covers an area of 43,000 square miles (111,369 km). The official language is English. Over 20 indigenous languages are spoken, reflecting the country's ethnic and cultural diversity. The capital and largest city is Monrovia.

Liberia began in the early 19th century as a project of the American Colonization Society (ACS), which believed that black people would face better chances for freedom and prosperity in Africa than in the United States. Between 1822 and the outbreak of the American Civil War in 1861, more than 15,000 freed and free-born African Americans, along with 3,198 Afro-Caribbeans, relocated to Liberia. Gradually developing an Americo-Liberian identity, the settlers carried their culture and tradition with them while colonizing the indigenous population. Led by the Americo-Liberians, Liberia declared independence on July 26, 1847, which the U.S. did not recognize until February 5, 1862.

Mali, officially the Republic of Mali, is a landlocked country in West Africa. It is the eighth-largest country in Africa and the 23rd largest country in the world, with an area of over 1,240,192 square kilometres (478,841 sq mi). The country is bordered to the north by Algeria, to the east by Niger, to the northwest by Mauritania, to the south by Burkina Faso and Ivory Coast, and to the west by Guinea and Senegal. The population of Mali is about 23.29 million, 47.19% of which are estimated to be under the age of 15 in 2024. Its capital and largest city is Bamako. The country has 13 official languages, of which Bambara is the most commonly spoken.

The sovereign state's northern borders reach deep into the middle of the Sahara Desert. The country's southern part, where the majority of inhabitants live, is in the Sudanian savanna and has the Niger and Senegal rivers running through it. The country's economy centres on agriculture and mining with its most prominent natural resources including gold (of which it is the third largest producer in Africa) and salt.

Senegal, officially the Republic of Senegal, is the westernmost country in West Africa, situated along the Atlantic Ocean coast. It borders Mauritania to the north, Mali to the east, Guinea to the southeast and Guinea-Bissau to the southwest. Senegal nearly surrounds The Gambia, a country occupying a narrow strip of land along the banks of the Gambia River, which separates Senegal's southern region of Casamance from the rest of the country. It also shares a maritime border with Cape Verde. The capital and largest city of Senegal is Dakar.

Senegal is the westernmost country in the mainland of the Old World, or Afro-Eurasia. It owes its name to the Senegal River, which borders it to the north and east. The climate is typically Sahelian, with a rainy season. Senegal covers a land area of almost 197,000 square kilometres (76,000 sq mi) and has a population of around 18 million. The state is a presidential republic; since the country's foundation in 1960, it has been recognized as one of the most stable countries on the African continent. On the 2024 V-Dem Democracy Indices, Senegal is ranked 68th in electoral democracy worldwide and 10th in electoral democracy in Africa.

French West Africa (French: Afrique-Occidentale française, AOF) was a federation of eight French colonial territories in West Africa: Mauritania, Senegal, French Sudan (now Mali), French Guinea (now Guinea), Ivory Coast, Upper Volta (now Burkina Faso), Dahomey (now Benin) and Niger. The federation existed from 1895 until 1958. Its capital was Saint-Louis in Senegal until 1902, and then Dakar until the federation's collapse in 1960.

With an area of 4,689,000 km, French West Africa was eight times the size of Metropolitan France. French Equatorial Africa had an additional area of 2,500,000 km.

A refugee camp is a temporary settlement built to receive refugees and people in refugee-like situations. Refugee camps usually accommodate displaced people who have fled their home country, but camps are also made for internally displaced people. Usually, refugees seek asylum after they have escaped war in their home countries, but some camps also house environmental and economic migrants. Camps with over a hundred thousand people are common, but as of 2012, the average-sized camp housed around 11,400. They are usually built and run by a government, the United Nations, international organizations (such as the International Committee of the Red Cross), or non-governmental organization. Unofficial refugee camps, such as Idomeni in Greece or the Calais jungle in France, are where refugees are largely left without the support of governments or international organizations.

Refugee camps generally develop in an impromptu fashion with the aim of meeting basic human needs for only a short time. Facilities that make a camp look or feel more permanent are often prohibited by host country governments. If the return of refugees is prevented (often by civil war), a humanitarian crisis can result or continue.

The Senegal River (Serer: "Seen O Gal" or "Senegal" - compound of the Serer term "Seen" or "Sene" or "Sen" (from Roog Seen, Supreme Deity in Serer religion) and "O Gal" (meaning "body of water")); Wolof: Dexug Senegaal, Arabic: نهر السنغال, romanized: Nahr as-Siniġāl, Hassaniyya pronunciation: [nahrˤ əs.säjnigaːl], French: Fleuve Sénégal) is a 1086-kilometre-long (675 mi) river in West Africa; much of its length marks part of the border between Senegal and Mauritania. It has a drainage basin of 270000 km (100000 sq mi), a mean flow of 680 m/s (24,000 cu ft/s), and an annual discharge of 21.5 km (5.2 cu mi). Important tributaries are the Falémé River, Karakoro River, and the Gorgol River. The river divides into two branches once it passes Kaédi. The left branch, called the Doué, runs parallel to the main river to the north. After 200 km (120 mi) the two branches rejoin a few kilometers downstream of Podor.

In 1972 Mali, Mauritania and Senegal founded the Organisation pour la mise en valeur du fleuve Sénégal (OMVS) to manage the river basin. Guinea joined in 2005. As of 2012, only very limited use was made of the river for the transportation of goods and passengers. The OMVS have looked at the feasibility of creating a navigable channel 55 m (180 ft) in width between the small town of Ambidédi in Mali and Saint-Louis, a distance of 905 km (562 mi). It would give landlocked Mali a direct route to the Atlantic Ocean.

African French (French: français africain) is the umbrella grouping of varieties of the French language spoken throughout Francophone Africa. Used mainly as a secondary language or lingua franca, it is spoken by an estimated 320 million people across 34 countries and territories, some of which are not Francophone, but merely members or observers of the Organisation internationale de la Francophonie. Of these, 19 sovereign states recognize it as an official de jure language, though it is not the native tongue of the majority. According to Ethnologue, only 1,2 million people spoke it as a first language. African French speakers represent 67% of the Francophonie, making Africa the continent with the most French speakers in the world.

In Africa, French is often spoken as a second language alongside the Indigenous ones, but in a small number of urban areas (in particular in Central Africa and in the ports located on the Gulf of Guinea) it has become a first language, such as in the region of Abidjan, Côte d'Ivoire, the Democratic Republic of Congo, in the urban areas of Douala, Yaoundé in Cameroon, in Libreville, Gabon, and Antananarivo.

The Paleotropical kingdom (Paleotropis) is a floristic kingdom composed of the tropical areas of Africa, Asia and Oceania (excluding Australia and New Zealand), as proposed by Ronald Good and Armen Takhtajan. Part of its flora is inherited from the ancient supercontinent of Gondwana or exchanged later (e.g. Piperaceae with pantropical distribution and but few warm temperate representatives). These Gondwanan lineages are related to those in the Neotropical kingdom, composed of the tropical areas of Central and South America. Flora from the Paleotropical kingdom influenced the tropical flora of the Australian Kingdom. The kingdom is subdivided into five floristic subkingdoms according to Takhtajan (or three, according to Good) and about 13 floristic regions. In this article the floristic subkingdoms and regions are given as delineated by Takhtajan.

Female education is a catch-all term for a complex set of issues and debates surrounding education (primary education, secondary education, tertiary education, and health education in particular) for girls and women. It is frequently called girls' education or women's education. It includes areas of gender equality and access to education. The education of women and girls is important for the alleviation of poverty. Broader related topics include single-sex education and religious education for women, in which education is divided along gender lines.

Inequalities in education for girls and women are complex: women and girls face explicit barriers to entry to school, for example, violence against women or prohibitions of girls from going to school, while other problems are more systematic and less explicit, for example, science, technology, engineering and mathematics (STEM) education disparities are deep rooted, even in Europe and North America. In some Western countries, women have surpassed men at many levels of education. For example, in the United States in 2020/2021, women earned 63% of associate degrees, 58% of bachelor's degrees, 62% of master's degrees, and 56% of doctorates.

Ivory Coast, also known as Côte d'Ivoire and officially the Republic of Côte d'Ivoire, is a country on the southern coast of West Africa. Its capital city of Yamoussoukro is located in the centre of the country, while its largest city and economic centre is the port city of Abidjan. It borders Guinea to the northwest, Liberia to the west, Mali to the northwest, Burkina Faso to the northeast, Ghana to the east, and the Atlantic Ocean's Gulf of Guinea to the south. With 31.5 million inhabitants in 2024, Ivory Coast is the third-most populous country in West Africa. Its official language is French, and indigenous languages are also widely used, including Bété, Baoulé, Dyula, Dan, Anyin, and Cebaara Senufo. In total, there are around 78 languages spoken in Ivory Coast. The country has a religiously diverse population, including numerous followers of Islam, Christianity, and traditional faiths often entailing animism.

Before its colonisation, Ivory Coast was home to several states, including Gyaaman, the Kong Empire, and Baoulé. The area became a protectorate of France in 1843 and was consolidated as a French colony in 1893 amid the Scramble for Africa. It achieved independence in 1960, led by Félix Houphouët-Boigny, who ruled the country until 1993. Relatively stable by regional standards, Ivory Coast established close political-economic ties with its West African neighbours while maintaining close relations with the West, especially France. Its stability was diminished by a coup d'état in 1999 and two civil wars—first between 2002 and 2007 and again during 2010–2011. It adopted a new constitution in 2016.

Guinea-Bissau, officially the Republic of Guinea-Bissau, is a country in West Africa that covers 36,125 square kilometres (13,948 sq mi) with an estimated population of 2,026,778. It borders Senegal to its north and Guinea to its southeast.

Guinea-Bissau was once part of the kingdom of Kaabu, as well as part of the Mali Empire. Parts of this kingdom persisted until the 18th century, while a few others had been under some rule by the Portuguese Empire since the 16th century. In the 19th century, it was colonised as Portuguese Guinea. Upon independence, declared in 1973 and recognised in 1974, the name of its capital, Bissau, was added to the country's name to prevent confusion with Guinea (formerly French Guinea). Guinea-Bissau has had a history of political instability since independence. About 2% of the population speaks Portuguese, the official language, as a first language, and 33% speak it as a second language. Guinea-Bissau Creole, a Portuguese-based creole, is the national language and also considered the language of unity. According to a 2012 study, 54% of the population speak Creole as a first language and about 40% speak it as a second language. The remainder speak a variety of native African languages. The nation is home to numerous followers of Islam, Christianity, and multiple traditional faiths. The country's per capita gross domestic product is one of the lowest in the world.

Serandite is a mineral with formula Na(Mn,Ca)₂Si₃O₈(OH). The mineral was discovered in Guinea in 1931 and named for J. M. Sérand. Serandite is generally red, brown, black or colorless. The correct name lacks an accent.

Sierra Leone, officially the Republic of Sierra Leone, is a country on the west coast of West Africa. It is bordered to the southeast by Liberia and by Guinea to the north. Sierra Leone's land area is 73,252 km (28,283 sq mi). It has a tropical climate and environments ranging from savannas to rainforests. As of the 2023 census, Sierra Leone has a population of 8,460,512. Freetown is its capital and largest city.

Sierra Leone is a presidential republic, with a unicameral parliament and a directly elected president. It is a secular state. Its constitution provides for the separation of state and religion and freedom of conscience. Muslims constitute three-quarters of the population, and there is a significant Christian minority. Religious tolerance is very high.

Elaeis guineensis is a species of palm commonly just called oil palm but also sometimes African oil palm or macaw-fat. The first Western person to describe it and bring back seeds was the French naturalist Michel Adanson.

It is native to west and southwest Africa, specifically the area between Angola and The Gambia; the species name, guineensis, refers to the name for the area called Guinea, and not the modern country Guinea now bearing that name. The species is also now naturalised in Madagascar, Sri Lanka, Malaysia, Indonesia, Central America, Cambodia, the West Indies, and several islands in the Indian and Pacific Oceans. The closely related American oil palm E. oleifera and a more distantly related palm, Attalea maripa, are also used to produce palm oil.

The Liberia–Sierra Leone border is 299 km (185 mi) in length and runs from the tripoint with Guinea in the north-east to the Atlantic Ocean in the south-west.

The Ivory Coast–Liberia border is 778 km (483 mi) in length and runs from the tripoint with Guinea in the north down to the Atlantic Ocean in the south. It separates the Liberian counties of Grand Gedeh, River Gee, Maryland and Nimba from the Ivorian districts of Montagnes and Bas-Sassandra.
