Rivers State
–
Rivers State, also known simply as Rivers, is one of the 36 states of Nigeria. According to census data released in 2006, the state has a population of 5,185,400 and its capital, Port Harcourt is the largest city and is economically significant as the centre of Nigerias oil industry. Rivers State is bounded on the South by the Atlantic Ocean, to the North by Imo, Abia and Anambra States, to the East by Akwa Ibom State and to the West by Bayelsa and Delta states. It is home to indigenous ethnic groups, Ikwerre, Ibani, Opobo, Eleme, Okrika. The people from Rivers State are known as Riverians, the inland part of the state consists of tropical rainforest, towards the coast the typical Niger Delta environment features many mangrove swamps. Rivers State, named after the rivers that border its territory, was part of the Oil Rivers Protectorate from 1885 till 1893. In 1900 the region was merged with the territories of the Royal Niger Company to form the colony of Southern Nigeria. The state was formed in 1967 with the split of the Eastern Region of Nigeria, until 1996 the state contained the area now known as Bayelsa State. In the early days of the period, several protection treaties were signed between various indigenous communities and the British colonial government. Between 1941 and 1952, agitation for the creation of Rivers province began with the formation of the Ijo Rivers Peoples League. By 1953, the Council of Rivers Chiefs was birthed as a replacement body for the League, the year, another organisation. The Council of Rivers Chiefs was later renamed in 1954 to Rivers Chiefs and Peoples Congress and in 1956, until 1958, hopes of an independent state resonated with the region, and lingered consistently in the minds of its natives. During the constitutional conference that year, the countrys nationhood was affirmed while an agreement was reached on some measures to mitigate the fears of the minorities in the area. Around this time, the COR State Movement had broken away to press their own case, thereafter, the British launched a commission led by Sir Henry Willink to look into the misgivings of these autochthons. The Willink Commission initiated the conception of the Niger Delta Development Board, the purpose was to tackle the problems of underdevelopment, however, this failed to rise to the expectations of the masses. After much discontent, some of the people attempted to take the route to achieve their goals. In February 1966, Isaac Boro, Sam Owonaro and Nottingham Dick alongside their supporters proclaimed a Delta Peoples Republic, the rebellion was immediately crushed by the Federal and the old Eastern Nigeria government. On 27 May 1967, under the administration of General Yakubu Gowon, decree No.14 was issued, the state government has executive and legislative branches, with an independent judiciary

River delta
–
A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, River deltas are ecologically important as they provide coastline defense, are home to many species, and can impact drinking water supply. The tidal currents also cannot be too strong, as sediment would wash out into the body faster than the river deposits it. Of course, the river must carry enough sediment to layer into deltas over time, the rivers velocity decreases rapidly, causing it to deposit the majority, if not all, of its load. This alluvium builds up to form the river delta, when the flow enters the standing water, it is no longer confined to its channel and expands in width. This flow expansion results in a decrease in the flow velocity, as a result, sediment drops out of the flow and deposits. Over time, this single channel builds a deltaic lobe, pushing its mouth into the standing water, as the deltaic lobe advances, the gradient of the river channel becomes lower because the river channel is longer but has the same change in elevation. As the slope of the channel decreases, it becomes unstable for two reasons. First, gravity makes the flow in the most direct course down slope. If the river breaches its natural levees, it out onto a new course with a shorter route to the ocean. Second, as its slope gets lower, the amount of stress on the bed decreases, which results in deposition of sediment within the channel. This makes it easier for the river to breach its levees, often when the channel does this, some of its flow remains in the abandoned channel. When these channel-switching events occur, a mature delta develops a distributary network, another way these distributary networks form is from deposition of mouth bars. When this mid-channel bar is deposited at the mouth of a river and this results in additional deposition on the upstream end of the mouth-bar, which splits the river into two distributary channels. A good example of the result of this process is the Wax Lake Delta, in both of these cases, depositional processes force redistribution of deposition from areas of high deposition to areas of low deposition. This results in the smoothing of the shape of the delta as the channels move across its surface. Because the sediment is laid down in fashion, the shape of these deltas approximates a fan. The more often the flow changes course, the shape develops as closer to an ideal fan, the Mississippi and Ural River deltas, with their birds-feet, are examples of rivers that do not avulse often enough to form a symmetrical fan shape

Niger River
–
The Niger River is the principal river of western Africa, extending about 4,180 km. Its drainage basin is 2,117,700 km2 in area and its source is in the Guinea Highlands in southeastern Guinea. The Niger is the third-longest river in Africa, exceeded only by the Nile and its main tributary is the Benue River. The Scottish explorer Mungo Park was the first Westerner known to have travelled to the portion of the Niger River. The earliest use of the name Niger for the river is by Leo Africanus in his Della descrittione dell’Africa et delle cose notabili che iui sono published in Italian in 1550, the name may come from Berber phrase ger-n-ger meaning river of rivers. As Timbuktu was the end of the principal Trans-Saharan trade route to the western Mediterranean. When European colonial powers began to send ships along the West coast of Africa in the 16th and 17th centuries, the Niger Delta, pouring into the Atlantic through mangrove swamps and thousands of distributaries along more than 160 kilometres, was thought to be no more than coastal wetlands. The Niger River is a clear river, carrying only a tenth as much sediment as the Nile because the Nigers headwaters lie in ancient rocks that provide little silt. Like the Nile, the Niger floods yearly, this begins in September, peaks in November, an unusual feature of the river is the Inner Niger Delta, which forms where its gradient suddenly decreases. The result is a region of braided streams, marshes, and lakes the size of Belgium, the river loses nearly two-thirds of its potential flow in the Inner Delta between Ségou and Timbuktu to seepage and evaporation. All the water from the Bani River, which flows into the Delta at Mopti, the average loss is estimated at 31 km3/year, but varies considerably between years. The river is joined by various tributaries, but also loses more water to evaporation. The quantity of water entering Nigeria measured in Yola was estimated at 25 km3/year before the 1980s, the most important tributary of the Niger in Nigeria is the Benue River which merges with the river at Lokoja in Nigeria. The Niger takes one of the most unusual routes of any major river and this strange geography apparently came about because the Niger River is two ancient rivers joined together. Over time upstream erosion by the lower Niger resulted in capture of the upper Niger by the lower Niger. The northern part of the river, known as the Niger bend, is an important area because it is the major river and this made it the focal point of trade across the western Sahara, and the centre of the Sahelian kingdoms of Mali and Gao. The surrounding Niger River Basin is one of the distinct physiographic sections of the Sudan province, the origin of the rivers name remains unclear. What is clear is that Niger was an appellation applied in the Mediterranean world from at least the Classical era, when knowledge of the area by Europeans was slightly better than fable

Atlantic Ocean
–
The Atlantic Ocean is the second largest of the worlds oceans with a total area of about 106,460,000 square kilometres. It covers approximately 20 percent of the Earths surface and about 29 percent of its surface area. It separates the Old World from the New World, the Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Eurasia and Africa to the east, and the Americas to the west. The Equatorial Counter Current subdivides it into the North Atlantic Ocean, in contrast, the term Atlantic originally referred specifically to the Atlas Mountains in Morocco and the sea off the Strait of Gibraltar and the North African coast. The Greek word thalassa has been reused by scientists for the huge Panthalassa ocean that surrounded the supercontinent Pangaea hundreds of years ago. The term Aethiopian Ocean, derived from Ancient Ethiopia, was applied to the Southern Atlantic as late as the mid-19th century, many Irish or British people refer to the United States and Canada as across the pond, and vice versa. The Black Atlantic refers to the role of ocean in shaping black peoples history. Irish migration to the US is meant when the term The Green Atlantic is used, the term Red Atlantic has been used in reference to the Marxian concept of an Atlantic working class, as well as to the Atlantic experience of indigenous Americans. Correspondingly, the extent and number of oceans and seas varies, the Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait, Greenland Sea, Norwegian Sea, to the east, the boundaries of the ocean proper are Europe, the Strait of Gibraltar and Africa. In the southeast, the Atlantic merges into the Indian Ocean, the 20° East meridian, running south from Cape Agulhas to Antarctica defines its border. In the 1953 definition it extends south to Antarctica, while in later maps it is bounded at the 60° parallel by the Southern Ocean, the Atlantic has irregular coasts indented by numerous bays, gulfs, and seas. Including these marginal seas the coast line of the Atlantic measures 111,866 km compared to 135,663 km for the Pacific. Including its marginal seas, the Atlantic covers an area of 106,460,000 km2 or 23. 5% of the ocean and has a volume of 310,410,900 km3 or 23. 3%. Excluding its marginal seas, the Atlantic covers 81,760,000 km2 and has a volume of 305,811,900 km3, the North Atlantic covers 41,490,000 km2 and the South Atlantic 40,270,000 km2. The average depth is 3,646 m and the maximum depth, the bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge. It runs from 87°N or 300 km south of the North Pole to the subantarctic Bouvet Island at 42°S, the MAR divides the Atlantic longitudinally into two halves, in each of which a series of basins are delimited by secondary, transverse ridges. The MAR reaches above 2000 m along most of its length, the MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the other

Nigeria
–
Its coast in the south lies on the Gulf of Guinea in the Atlantic Ocean. It comprises 36 states and the Federal Capital Territory, where the capital, Nigeria is officially a democratic secular country. Modern-day Nigeria has been the site of numerous kingdoms and tribal states over the millennia, the modern state originated from British colonial rule beginning in the 19th century, and the merging of the Southern Nigeria Protectorate and Northern Nigeria Protectorate in 1914. The British set up administrative and legal structures whilst practising indirect rule through traditional chiefdoms, Nigeria became a formally independent federation in 1960, and plunged into a civil war from 1967 to 1970. Nigeria is often referred to as the Giant of Africa, owing to its large population, with approximately 184 million inhabitants, Nigeria is the most populous country in Africa and the seventh most populous country in the world. Nigeria has one of the largest populations of youth in the world, Nigeria is divided roughly in half between Christians, who live mostly in the southern part of the country, and Muslims in the northern part. A minority of the population practise religions indigenous to Nigeria, such as native to the Igbo. As of 2015, Nigeria is the worlds 20th largest economy, worth more than $500 billion and $1 trillion in terms of nominal GDP and it overtook South Africa to become Africas largest economy in 2014. The 2013 debt-to-GDP ratio was 11 percent, Nigeria is a member of the MINT group of countries, which are widely seen as the globes next BRIC-like economies. It is also listed among the Next Eleven economies set to become among the biggest in the world, Nigeria is a founding member of the African Union and a member of many other international organizations, including the United Nations, the Commonwealth of Nations and OPEC. The name Nigeria was taken from the Niger River running through the country and this name was coined in the late 19th century by British journalist Flora Shaw, who later married Lord Lugard, a British colonial administrator. The origin of the name Niger, which applied only to the middle reaches of the Niger River, is uncertain. The word is likely an alteration of the Tuareg name egerew n-igerewen used by inhabitants along the middle reaches of the river around Timbuktu prior to 19th-century European colonialism. The Nok civilisation of Northern Nigeria flourished between 500 BC and AD200, producing life-sized terracotta figures which are some of the earliest known sculptures in Sub-Saharan Africa, further north, the cities Kano and Katsina have a recorded history dating to around 999 AD. Hausa kingdoms and the Kanem-Bornu Empire prospered as trade posts between North and West Africa, the Kingdom of Nri of the Igbo people consolidated in the 10th century and continued until it lost its sovereignty to the British in 1911. Nri was ruled by the Eze Nri, and the city of Nri is considered to be the foundation of Igbo culture, Nri and Aguleri, where the Igbo creation myth originates, are in the territory of the Umeuri clan. Members of the clan trace their lineages back to the patriarchal king-figure Eri, in West Africa, the oldest bronzes made using the lost-wax process were from Igbo Ukwu, a city under Nri influence. The Yoruba kingdoms of Ife and Oyo in southwestern Nigeria became prominent in the 12th and 14th centuries, the oldest signs of human settlement at Ifes current site date back to the 9th century, and its material culture includes terracotta and bronze figures

Palm oil
–
Palm oil is naturally reddish in color because of a high beta-carotene content. It is not to be confused with palm oil derived from the kernel of the same fruit. The differences are in color, and in saturated fat content, palm oil is 49% saturated, while palm kernel oil and coconut oil are 81% and 86% saturated fats. Along with coconut oil, palm oil is one of the few highly saturated vegetable fats and is semisolid at room temperature, Palm oil is a common cooking ingredient in the tropical belt of Africa, Southeast Asia and parts of Brazil. Its use in the food industry in other parts of the world is widespread because of its lower cost. In 2004, a group called the Roundtable on Sustainable Palm Oil was formed to work with the palm oil industry to address these concerns. It is believed that traders brought the oil palm to Egypt, Palm oil from E. guineensiss has long been recognized in West and Central African countries, and is widely used as a cooking oil. European merchants trading with West Africa occasionally purchased palm oil for use as an oil in Europe. Palm oil became a highly sought-after commodity by British traders, for use as a lubricant for machinery during Britains Industrial Revolution. Palm oil formed the basis of soap products, such as Lever Brothers Sunlight soap, by around 1870, palm oil constituted the primary export of some West African countries, such as Ghana and Nigeria, although this was overtaken by cocoa in the 1880s. Palm oil, like all fats, is composed of fatty acids, Palm oil has an especially high concentration of saturated fat, specifically, of the 16-carbon saturated fatty acid palmitic acid, to which it gives its name. Monounsaturated oleic acid is also a constituent of palm oil. Unrefined palm oil is a significant source of tocotrienol, part of the vitamin E family. The approximate concentration of fatty acids in palm oil is, Red palm oil is rich in carotenes, such as alpha-carotene, beta-carotene and lycopene, many processed foods either contain palm oil or various ingredients derived from it. After milling, various oil products are made using refining processes. First is fractionation, with crystallization and separation processes to obtain solid, then melting and degumming removes impurities. Then the oil is filtered and bleached, RBDPO is the basic palm oil product sold on the worlds commodity markets. Many companies fractionate it further to produce palm olein for cooking oil, since the mid-1990s, red palm oil has been cold-pressed and bottled for use as cooking oil, and blended into mayonnaise and salad oil

Efik people
–
The Efik are an ethnic group located primarily in southeastern Nigeria, in the southern part of Cross River State. The Efik speak the Efik language which is a Benue–Congo language of the Cross River family, Efik oral histories tell of migration down the Cross River from Arochukwu to found numerous settlements in the Calabar and Creek Town area. Creek Town and its environs are often referred to as Calabar. Calabar is not to be confused with the Kalabari Kingdom in Rivers State which is an Ijaw state to its west, Cross River State with Akwa Ibom State was formerly one of the original twelve states of Nigeria known as the Southeastern State. The Efik people also occupy southwestern Cameroon including Bakassi and this separation was further extended when as a result of a 1961 plebiscite the area voted to join the Republic of Cameroon. Most of the area was transferred, but in August 2006 - Nigeria handed over the Bakassi peninsula to Cameroon. The people of Uruan were said to have them the name Efik deriving from a verb meaning to press or oppress. The Efik people are found in the South-South geopolitical zone of Nigeria, in “the South Eastern corner of the Cross River State. ”They occupy the basins of the Lower Cross River and down to the Bakassi Peninsula, the Calabar River and down to its tributaries – the Kwa River, Akpayafe and the Eniong Creek. ”They occupied Calabar “towards the end of the century or at the beginning of the 18th century. ”The Efik are related to the Annang, Ibibio, Igbo, Oron, Biase, Akampkpa, Uruan. Although the actual origins of the Efik people are unknown, oral traditions provide accounts of their migration from Igbo and they had sojourned from Nubia through to Ghana and then Arochukwu in present-day South East Nigeria. After staying there harmoniously as guests for about 400 years, they left after a disagreement with the Aros, the bulk of them left to Uruan in present-day Akwa Ibom State, some to Eniong and surrounding areas. They stayed in Uruan for about a hundred or so years and then moved to Ikpa Ene, there would seem to be three successive stages in the history of efik migration and settlement, an Igbo phase an Ibibio phase and the drift to the coast. There are some Efik who advocate the oriental origins of their people and this is believed to be elaborated in some of their peculiar burial sites and ceremonies. Although their economy was based on fishing, the area quickly developed into a major trading centre. Incoming European goods were traded for slaves, palm oil and other palm products, the Efik kings collected a trading tax called comey from docking ships until the British replaced it with comey subsidies. The diary of Antera Duke, an Efik, is the surviving record from an African slave-trading house. The Efik were the men between the white traders on the coast and the inland tribes of the Cross River and Calabar district. Christian missions were at work among the Efiks beginning in the middle of the 19th century, even by 1900, many of the native peoples were well educated in European ideologies and culture, professed Christianity and dressed in European fashion. In 1884 the Efik kings and the chiefs of the Efik placed themselves under British protection and these treaties and attendant territorial economic rights, are documented in CAP23 of Laws of Eastern Nigeria, captioned Comey subsidies law

Igbo people
–
The Igbo people, also erroneously known as the Ibo people, are an indigenous linguistic and cultural people of southern Nigeria. Geographically, the Igbo homeland is divided into two sections by the Niger River – an eastern and a western section. They speak Igbo, which includes various Igboid languages and dialects, the Igbo homeland is almost surrounded on all sides by other ethnic peoples of southern and central Nigeria namely, the Ijaw, Edo, Isoko, Ogoni, Igala, Tiv, Yako, Idoma and Ibibio. The Igbo people are one of the largest ethnic groups in Africa, in rural Nigeria, Igbo people work mostly as craftsmen, farmers and traders. The most important crop is the yam, celebrations take place annually to celebrate its harvesting, other staple crops include cassava and taro. Before British colonial rule, the Igbo were a politically fragmented group, there were variations in culture such as in art styles, attire and religious practices. Various subgroups were organized by clan, lineage, village affiliation, there were not many centralized chiefdoms, hereditary aristocracy, or kingship customs except in kingdoms such as those of the Nri, Arochukwu, Agbor and Onitsha. This political system changed significantly under British colonialism in the early 20th century, the Igbo became overwhelmingly Christian under colonization. Chinua Achebes Things Fall Apart is one of the most popular novels to depict Igbo culture, by the mid-20th century, the Igbo people developed a strong sense of ethnic identity. Certain conflicts with other Nigerian ethnicities led to Igbo-densely populated Eastern Nigeria seceding to create the independent state of Biafra, the Nigerian Civil War or the Nigerian-Biafran War broke out shortly after. With their defeat, the Republic of Biafra once again was part of Nigeria, MASSOB, a sectarian organization formed in 1999, continues a non-violent struggle for an independent Igbo state. Due to the effects of migration and the Atlantic slave trade, there are descendant ethnic Igbo populations in such as Cameroon and Equatorial Guinea. Their exact population outside Africa is unknown, but today many African Americans, according to Liberian historians the fifth president of Liberia Edward James Roye was of Igbo descent. The Igbo people have had fragmented and politically independent communities, before knowledge of Europeans and full exposure to other neighbouring ethnic groups, the Igbo did not have a strong identity as one people. As in the case of most ethnic groups, the British, Chinua Achebe, among other scholars, challenged this because of its negative connotations and possible wrong definition. He suggested defining the Igbo people as a nation although the Igbo do not have an officially recognized state of their own. The most common name for the Igbo in English was formerly Ibo and they have also been known as the Iboe, Ebo, Eboe, Eboans, or Heebo. Their territory and main settlement have also been known by their name

Yoruba people
–
Yoruba people are an ethnic group of Southwestern and North Central Nigeria as well as Southern and Central Benin, together known as Yorubaland. The Yoruba constitute over 40 million people in total, the majority of this population is from Nigeria and make up 21% of its population, according to the CIA World Factbook, making them one of the largest ethnic groups in Africa. The majority of the Yoruba speak the Yoruba language, which is tonal, the Yoruba share borders with the Bariba to the northwest in Benin, the Nupe to the north, and the Ebira to the northeast in central Nigeria. To the east are the Edo, Ẹsan, and the Afemai groups in mid-western Nigeria, adjacent the Ebira and Edo groups are the related Igala people found in the northeast to the left bank of the Niger river. To the southwest are the Gbe speaking Mahi, Egun, Fon and Ewe who border Yoruba communities in Benin, to the southeast are Itsekiri who live in the north-west end of the Niger delta. They are ancestrally related to the Yoruba but chose to maintain a cultural identity. Significant Yoruba populations in other West African countries can be found in Ghana, Ivory Coast, Liberia and this older group has communities in such countries as Cuba, Dominican Republic, Saint Lucia, Jamaica, Brazil, Grenada, Trinidad and Tobago, among others. As an ethnic description, the word Yoruba was first recorded in reference to the Oyo Empire in a written by the 16th-century Songhai scholar Ahmed Baba. It was popularized by Hausa usage and ethnography written in Arabic and Ajami during the 19th century, the extension of the term to all speakers of dialects related to the language of the Oyo dates to the second half of the 19th century. It is due to the influence of Samuel Ajayi Crowther, the first Anglican bishop in Nigeria, Crowther was himself a Yoruba and compiled the first Yoruba dictionary as well as introducing a standard for Yoruba orthography. The number of speakers is estimated at about 30 million in 2010. Yoruba is classified within the Edekiri languages, which together with the isolate Igala, Igala and Yoruba have important historical and cultural relationships. The languages of the two ethnic groups bear such a close resemblance that researchers such as Forde and Westermann and Bryan regarded Igala as a dialect of Yoruba, the Yoruboid languages are assumed to have developed out of an undifferentiated Volta-Niger group by the 1st millennium BCE. There are three dialect areas, Northwest, Central, and Southeast. The area where North-West Yoruba is spoken corresponds to the historical Oyo Empire, south-East Yoruba was probably associated with the expansion of the Benin Empire after c. Central Yoruba forms an area in that the lexicon has much in common with NWY. Though for a part based on the Oyo and Ibadan dialects. As of the 7th century BCE the African peoples who lived in Yorubaland were not initially known as the Yoruba, although they shared a common ethnicity, by the 8th century, a powerful Yoruba kingdom already existed in Ile-Ife, one of the earliest in Africa

Urhobo people
–
The Urhobos are people of southern Nigeria, near the northwestern Niger delta. The Urhobo is the ethnic group in Delta State. Delta State is one of the 36 states of the Federal Republic of Nigeria, the Urhobos speak the Urhobo language. The Urhobo culture is related to cultures in the Niger-Delta. Isoko is closely related in language and culture, leading to the missionaries erroneously labelling the Urhobo and this name was strongly rejected by both tribes. However, there are those of the opinion that Isoko is a dialect of Urhobo, the Urhobo nation is made up of twenty four sub-groups, including Okpe the largest of all Urhobo sub-groups. Isoko used to be regarded as a part of Urhobo nation until the late 1950s when they were granted autonomy, there are about two million Urhobos. The word Urhobo refer to a group of people and not the geographical territory, the Urhobos have social and cultural affinity to the Edo speaking people of Nigeria. The Urhobo now live in a territory bounded by latitudes 6°and 5°, 15° North and Longitudes 5°, 40° and 6°, 25° East in the Delta State and Bayelsa State of Nigeria. Their neighbours are the Isoko to the South East, the Itsekiri to the West, the Urhobo territory consist of evergreen forest with many oil palm trees which provide the lucrative palm produce industry for which the Urhobo have some technological preserve. The territory is covered by a network of streams whose volumes of water and flow are directly concerned with the season, wet season. The Urhobos are currently organized as kingdoms, gerontocracy and plutocracies. Although it is not clear which kingship is older among the kingdoms, Urhobo politics and government structure occur at two levels kingdom level town level. Men and women of Urhobo heritage are organized either by elders based on the system and or based on rich. An outline of Urhobo indigenous government and politics have the titles and he is the symbol of his kingdoms, culture and also of his royal predecessors. His Councillors are called Otota, Ohoveworen or Okakoro, addressed collectively as Ilorogun, other title holders are the executioners and warriors called Ogbu. Historically, this region was the most pristine in all of Africa, until the Portuguese burst into its territories in the late fifteenth century, its forest peoples cultivated their own forms of civilization, untouched by outside influences. A bulk of the Urhobo people reside in the South Western states of Delta, ofoni is an Urhobo community in Sagbama Local Government Area in Bayelsa State of the Federal Republic of Nigeria

Gulf of Guinea
–
The Gulf of Guinea is the northeasternmost part of the tropical Atlantic Ocean between Cape Lopez in Gabon, north and west to Cape Palmas in Liberia. The intersection of the Equator and Prime Meridian is in the gulf, among the many rivers that drain into the Gulf of Guinea are the Niger and the Volta. The coastline on the gulf includes the Bight of Benin and the Bight of Bonny, the Niger River in particular deposited organic sediments out to sea over millions of years which became crude oil. The origin of the name Guinea is thought to be an area in the region, bovill gives a thorough description, The name Guinea is usually said to have been a corrupt form of the name Ghana, picked up by the Portuguese in the Maghrib. The present writer finds this unacceptable, the name Guinea has been in use both in the Maghrib and in Europe long before Prince Henrys time. A passage in Leo points to Guinea having been a form of Jenne, less famous than Ghana but nevertheless for many centuries famed in the Maghrib as a great market. The relevant passage reads, The Kingdom of Ghinea. called by the merchants of our nation Gheneoa, by the inhabitants thereof Genni and by the Portugals. But it seems probable that Guinea derives from aguinaou, the Berber for Negro. Marrakech has a gate, built in the century, called the Bab Aguinaou. The modern application of the name Guinea to the coast dates only from 1481, the name Guinea is still attached to the names of three countries in Africa, Guinea, Guinea-Bissau, and Equatorial Guinea, as well as New Guinea in Melanesia. The main river shedding its waters in the gulf is the Niger River, the Gulf of Guinea contains a number of islands, the largest of which are in a southwest-northeast chain, forming part of the Cameroon line of volcanoes. Annobón, also known as Pagalu or Pigalu, is an island that is part of Equatorial Guinea, bobowasi Island is an island off the west coast of Africa in the Gulf of Guinea that is part of Western region Ghana. Bioko is an island off the west coast of Africa in the Gulf of Guinea that is part of Equatorial Guinea, corisco is an island belonging to Equatorial Guinea. Elobey Grande and Elobey Chico are two small islands belonging to Equatorial Guinea, São Tomé and Príncipe is a Portuguese-speaking island nation in the Gulf of Guinea that became independent from Portugal in 1975. It is located off the western equatorial coast of Africa and consists of two islands, São Tomé and Príncipe and they are located about 140 kilometres apart and about 250 and 225 kilometres, respectively, off the northwestern coast of Gabon. Both islands are part of a volcanic mountain range. São Tomé, the southern island, is situated just north of the Equator.

Inner Niger Delta
–
The Inner Niger Delta, also known as the Macina or Masina, is a large area of lakes and floodplains in the semi-arid Sahel area of central Mali, just south of the Sahara desert. The delta consists of the course of the Niger River. The Niger is the longest river in West Africa, towns such as the river-port of Mopti, Sévaré and Djenné, with its mud-brick Great Mosque lie in the 400 km-long region. The Fulani and Dogon inhabit the Macina region and the surrounding area, most of the year the area has a hot and dry climate, with hot winds from the nearby Sahara raising the temperature up to 40°C. During the wet season, which lasts from July to September but lasts longer the further one goes. When the dry season comes, the Macina turns into a network of lakes, cattle, pearl millet, and rice are its important agricultural products. The Macina inland delta also provides water and fish for the Malians living there, due to its proximity to the widening Sahel, there have been concerns that the Macina may be getting less rain every year. In the early 19th century, Seku Amadu founded a Massina Empire in the region, the Massina fell to El Hadj Umar Talls Toucouleur Empire in 1862, who in turn fell to the French army. The region became a part of the country of Mali on its independence in 1960, the Niger inland Delta lies in the Sahelian zone, and has an ecosystem that is largely dependent on the amount of flooding it receives. Precipitation in the basins of the upper course of the Bani. The rising water floods varying parts of the delta area. This in turn, is influenced by the movement of the Intertropical Convergence Zone. A delay exists between the amount of precipitation and the maximum water level in the inland delta area. While the wet season lasts three months from July till September, the western and southern edges of the area are not flooded until early to mid-October. The consequence is that parts of the delta are flooded while the dry season is well under way, note that only the lowest patches are flooded annually, higher elevations receive flooding in more intermittent periods due to the changing degrees of waterlevel rises. This division in three zones, makes for patches that vary in their nature according to their proximity to a main body water. The Inland Delta forms a green oasis in its semi-arid surroundings and its vegetation growth is limited by the availability of water, thus giving patches more often or longer subject to flooding a denser and more tree-like vegetation cover. As said, flooding cycles follow the precipitation cycle, when classifying vegetation in a grass, shrub and tree layer, up to 80% of vegetation cover in the Sahel exists of grass
