supports: Population density (in agriculture: standing stock and standing crop) is a measurement of population per unit area or unit volume; it is a quantity of type number density. It is frequently applied to living organisms, and most of the time to humans. It is a key geographical term. A village is a clustered human settlement or community, larger than a hamlet but smaller than a town, with a population ranging from a few hundred to a few thousand. Though often located in rural areas, the term urban village is also applied to certain urban neighbourhoods. Villages are normally permanent, with fixed dwellings; however, transient villages can occur. Further, the dwellings of a village are fairly close to one another, not scattered broadly over the landscape, as a dispersed settlement. The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World". The natural environment encompasses all living and non-living things occurring naturally. The term is most often applied to the Earth or some part of Earth. This environment encompasses the interaction of all living species, climate, weather, and natural resources that affect human survival and economic activity. A water taxi or a water bus, also known as a sightseeing boat, is a watercraft used to provide public or private transport, usually, but not always, in an urban environment. Service may be scheduled with multiple stops, operating in a similar manner to a bus, or on demand to many locations, operating in a similar manner to a taxi. A boat service shuttling between two points would normally be described as a ferry rather than a water bus or taxi. An urban area is a human settlement with high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, towns, conurbations or suburbs. In urbanism, the term contrasts to rural areas such as villages and hamlets and in urban sociology or urban anthropology it contrasts with natural environment. The creation of early predecessors of urban areas during the urban revolution led to the creation of human civilization with modern urban planning, which along with other human activities such as exploitation of natural resources leads to human impact on the environment. Abuja is the capital city of Nigeria. It is located in the centre of Nigeria, within the Federal Capital Territory (FCT). Abuja is a planned city which was built mainly in the 1980s. It officially became Nigeria's capital on 12 December 1991, replacing Lagos, though the latter remains the country's most populous city. Abuja's geography is defined by Aso Rock, a monolith left by water erosion. The Presidential Complex, National Assembly, Supreme Court and much of the city extend to the south of the rock. Zuma Rock, a monolith, lies just north of the city on the road to Kaduna State. In anthropology and archaeology, the Urban Revolution is the process by which small, kin-based, nonliterate agricultural villages were transformed into large, socially complex, urban societies.  Urban morphology is the study of the form of human settlements and the process of their formation and transformation. The study seeks to understand the spatial structure and character of a metropolitan area, city, town or village by examining the patterns of its component parts and the pro\
  , ownership or control and occupation. Typically, analysis of physical form focuses on street pattern, lot (or, in the UK, plot) pattern and building pattern, sometimes referred to collectively as urban grain. Analysis of specific settlements is usually undertaken using cartographic sources and the process of development is deduced from comparison of historic maps.
  Special attention is given to how the physical form of a city changes over time and to how different cities compare to each other. Another significant part of this subfield deals with the study of the social forms which are expressed in the physical layout of a city, and, conversely, how physical form produces or reproduces various social forms. Africa is the world's second-largest and second-most-populous continent. At about 30.3 million km² (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20.4 % of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two "de facto" independent states with limited or no recognition. Benin City is a city (2006 est. pop. 1,147,188) and the capital of Edo State in southern Nigeria. It is a city approximately north of the Benin River. It is situated by road east of Lagos. Benin is the centre of Nigeria's rubber industry, but processing palm nuts for oil is also an important traditional industry. Urbanization refers to the population shift from rural to urban areas, "the gradual increase in the proportion of people living in urban areas", and the ways in which each society adapts to the change. It is predominantly the process by which towns and cities are formed and become larger as more people begin living and working in central areas. The United Nations projected that half of the world's population would live in urban areas at the end of 2008. It is predicted that by 2050 about 64% of the developing world and 86% of the developed world will be urbanized. That is equivalent to approximately 3 billion urbanites by 2050, much of which will occur in Africa and Asia. Notably, the United Nations has also recently projected that nearly all global population growth from 2016 to 2030 will be absorbed by cities, about 1.1 billion new urbanites over the next 14 years. The Gulf of Guinea is the northeasternmost part of the tropical Atlantic Ocean between Cape Lopez in Gabon, north and west to Cape Three Points in Western region Ghana. The intersection of the Equator and Prime Meridian (zero degrees latitude and longitude) is in the gulf. Port Harcourt ( Igbo : gw chá ; Pidgin : Po - ta - kot ) is the capital of Rivers State , Nigeria . It lies along the Bonny River and is located in the Niger Delta . According to the 2006 census , the Port Harcourt urban area has a population of 1,382,592 . The area that became Port Harcourt in 1912 was before that part of the farmlands of the Diobu village group of the Ikwerre , an Igbo sub-group . The colonial administration of Nigeria created the port to export coal from the collieries of Enugu located 243 kilometres ( 151 mi ) north of Port Harcourt , to which it was linked by a railway called the Eastern Line , also built by the British . In 1956 crude oil was discovered in commercial quantities at Oloibiri , and Port Harcourt 's economy turned to petroleum when the first shipment of Nigerian crude oil was exported through the city in 1958 . Through the benefits of the Nigerian petroleum industry , Port Harcourt was further developed , with aspects of modernisation such as overpasses and city blocks . Oil firms that currently have offices in the city include Royal Dutch Shell and Chevron . The main educational establishment in the city is the University of Port Harcourt , and the current Mayor of Port Harcourt is Chimbiko Akorolo . Port Harcourt 's primary airport is Port Harcourt International Airport , located on the outskirts of the city ; the Nigerian Air Force ( NAF ) base is the location of the only other airport in the city and is used by commercial airlines Aero Contractors and Virgin Nigeria ( now Air Nigeria ) for domestic flights . The exploitation of natural resources is the use of natural resources for economic growth, sometimes with a negative connotation of accompanying environmental degradation. It started to emerge on an industrial scale in the 19th century as the extraction and processing of raw materials (such as in mining, steam power, and machinery) developed much further than it had in preindustrial eras. During the 20th century, energy consumption rapidly increased. Today, about 80% of the worlds energy consumption is sustained by the extraction of fossil fuels, which consists of oil, coal and gas. Another non-renewable resource that is exploited by humans is subsoil minerals such as precious metals that are mainly used in the production of industrial commodities. Intensive agriculture is an example of a mode of production that hinders many aspects of the natural environment, for example the degradation of forests in a terrestrial ecosystem and water pollution in an aquatic ecosystem. As the world population rises and economic growth occurs, the depletion of natural resources influenced by the unsustainable extraction of raw materials becomes an increasing concern. Etche is a Local Government Area (LGA) in Rivers State, Nigeria, named after the Etche (Echie) people of Southern Nigeria. They also inhabit Omuma LGA; Etche/Omuma is a National Assembly constituency. Urbanism is the study of the characteristic ways of interaction of inhabitants of towns and cities (urban areas) with the built environment. It is a direct component of disciplines such as urban planning (the physical design and management of urban structures) and urban sociology (the study of urban life and culture). However, in some contexts internationally Urbanism is synonymous with Urban Planning, and the Urbanist refers to a Urban Planner. The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria. It is typically considered to be located within nine coastal southern Nigerian states, which include: all six states from the South South geopolitical zone, one state (Ondo) from South West geopolitical zone and two states (Abia and Imo) from South East geopolitical zone. Of all the states that the region covers, only Cross River is not an oil-producing state.  Bonny Island is situated at the southern edge of Rivers State in the Niger Delta of Nigeria near Port Harcourt. Ferries are the main form of transport to and from the island. The local language spoken in Bonny Island and Bonny Town are the Igbo language and Ibani. A federal republic is a federation of states with a republican form of government. At its core, the literal meaning of the word republic when used to reference a form of government means: "a country that is governed by elected representatives and by an elected leader (such as a president) rather than by a king or queen". A republic (from ) is a sovereign state, country, or government which is organized with a form of government in which power resides in elected individuals representing the citizen body and government leaders exercise power according to the rule of law. In modern times, the definition of a republic commonly refers to a government which excludes a monarch. Currently, 147 of the world's 206 sovereign states use the word "republic" as part of their official names; not all of these are republics in the sense of having elected governments, nor do all nations with elected governments use the word "republic" in their names. Niger (or ), officially the Republic of Niger, is a landlocked country in Western Africa, named after the Niger River. Niger is bordered by Libya to the northeast, Chad to the east, Nigeria and Benin to the south, Burkina Faso and Mali to the west, and Algeria to the northwest. Niger covers a land area of almost 1,270,000 km, making it the largest country in West Africa, with over 80 percent of its land area covered by the Sahara Desert. The country's predominantly Islamic population of about 19 million is mostly clustered in the far south and west of the country. The capital city is Niamey, located in the far-southwest corner of Niger. Chad ('), officially the Republic of Chad ('), is a landlocked country in Central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon and Nigeria to the southwest and Niger to the west. It is the fifth largest country in Africa in terms of area. In geography, statistics and archaeology, a settlement, locality or populated place is a community in which people live. A settlement can range in size from a small number of dwellings grouped together to the largest of cities with surrounding urbanized areas. Settlements may include hamlets, villages, towns and cities. A settlement may have known historical properties such as the date or era in which it was first settled, or first settled by a particular people. Infrastructure refers to structures, systems, and facilities serving the economy of a business, industry, country, city, town, or area, including the services and facilities necessary for its economy to function. Human impact on the environment or anthropogenic impact on the environment includes impacts on biophysical environments, biodiversity, and other resources. The term "anthropogenic" designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and was first used in English by British ecologist Arthur Tansley in reference to human influences on climax plant communities. The atmospheric scientist Paul Crutzen introduced the term "anthropocene" in the mid-1970s. The term is sometimes used in the context of pollution emissions that are produced as a result of human activities but applies broadly to all major human impacts on the environment. Ibadan is the state capital of Oyo State. With a population of over 3 million, it is the most populous city in the state, and the third most populous city in Nigeria, after Lagos and Kano; it is the country's largest city by geographical area. At Nigerian independence, Ibadan was the largest and most populous city in the country, and the third in Africa after Cairo and Johannesburg. West Africa, also called Western Africa and the West of Africa, is the westernmost subregion of Africa. West Africa has been defined as including 18 countries: Benin, Burkina Faso, the island nation of Cape Verde, Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Mali, Mauritania, Niger, Nigeria, the island of Saint Helena, Senegal, Sierra Leone, São Tomé and Príncipe and Togo. Bonny River is a river in Rivers State, Nigeria. Water taxis which move along the river provide the connection between Bonny Island and Port Harcourt, the capital of Rivers State, which lies alongside the river. Urban sociology is the sociological study of life and human interaction in metropolitan areas. It is a normative discipline of sociology seeking to study the structures, processes, changes and problems of an urban area and by doing so provide inputs for urban planning and policy making. In other words, it is the sociological study of cities and their role in the development of society.
  Like most areas of sociology, urban sociologists use statistical analysis, observation, social theory, interviews, and other methods to study a range of topics, including migration and demographic trends, economics, poverty, race relations and economic trends. A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. The Niger River is the principal river of western Africa, extending about . Its drainage basin is in area. Its source is in the Guinea Highlands in southeastern Guinea. It runs in a crescent through Mali, Niger, on the border with Benin and then through Nigeria, discharging through a massive delta, known as the Niger Delta or the Oil Rivers, into the Gulf of Guinea in the Atlantic Ocean. The Niger is the third-longest river in Africa, exceeded only by the Nile and the Congo River (also known as the Zaïre River). Its main tributary is the Benue River. Okrika is a port town in Rivers State, Nigeria, capital of the Local Government Area of the same name. The town is situated on a small island just south of Port Harcourt, making it a suburb of the much larger city. A civilization, or civilisation (see spelling differences), is any complex society characterized by urban development, social stratification, symbolic communication forms (typically, writing systems), and a perceived separation from and domination over the natural environment by a cultural elite. Civilizations are intimately associated with and often further defined by other socio-politico-economic characteristics, including centralization, the domestication of both humans and other organisms, specialization of labour, culturally ingrained ideologies of progress and supremacism, monumental architecture, taxation, societal dependence upon farming as an agricultural practice, and expansionism. Benin (or -; ), officially the Republic of Benin and formerly Dahomey, is a country in West Africa. It is bordered by Togo to the west, Nigeria to the east, and Burkina Faso and Niger to the north. A majority of the population live on its small southern coastline on the Bight of Benin, part of the Gulf of Guinea in the northernmost tropical portion of the Atlantic Ocean. The capital of Benin is Porto-Novo, but the seat of government is in Cotonou, the country's largest city and economic capital. Benin covers an area of 114,763 square kilometers and its population in 2015 was estimated to be approximately 10.88 million. Benin is a tropical, sub-Saharan nation, highly dependent on agriculture, with substantial employment and income arising from subsistence farming. In general, a rural area or countryside is a geographic area that is located outside towns and cities. The Health Resources and Services Administration of the U.S. Department of Health and Human Services defines the word "rural" as encompassing "...all population, housing, and territory not included within an urban area. Whatever is not urban is considered rural." 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, making it the sixth-most populous state in the country. Its capital, Port Harcourt is the largest city and is economically significant as the centre of Nigeria's 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 many indigenous ethnic groups: Ikwerre, Ibani, Opobo, Eleme, Okrika, and Kalabari, Etche, Ogba, Ogoni, Engenni, Obolo and others. The people from Rivers State are known as "Riverians". The Federal Republic of Nigeria , commonly referred to as Nigeria, is a federal republic in West Africa, bordering Benin in the west, Chad and Cameroon in the east, and Niger in the north. 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, Abuja is located. Its largest cities include: Lagos, Kano, Ibadan, Benin City and Port Harcourt. Nigeria is officially a democratic secular country. Kano is the state capital of Kano State in Northern West, Nigeria. It is situated in the Sahelian geographic region, south of the Sahara. Kano is the commercial nerve center of Northern Nigeria and is the second largest city in Nigeria, after Lagos. The Kano metropolis initially covered , and comprised six local government areas (LGAs)  Kano Municipal, Fagge, Dala, Gwale, Tarauni and Nasarawa; However, it now covers two additional LGAs  Ungogo and Kumbotso. The total area of Metropolitan Kano is now , with a population of 2,828,861 as of the 2006 Nigerian census. Lagos initially emerged as a port city which originated on a collection of islands, which are contained in the present day Local Government Areas (LGAs) of Lagos Island, Eti-Osa, Amuwo-Odofin and Apapa; the islands are separated by creeks, fringing the southwest mouth of Lagos Lagoon, while protected from the Atlantic Ocean by barrier islands and long sand spits such as Bar Beach, which stretch up to east and west of the mouth. Due to rapid urbanization, the city expanded to the west of the lagoon to include areas in the present day Lagos Mainland, Ajeromi-Ifelodun and Surulere. This led to the classification of Lagos into two main areas - the Island, which was the initial city of Lagos, before it expanded into the area known as the Mainland. This city area was governed directly by the Federal Government through the "Lagos City Council", until the creation of Lagos State in 1967, which led to the splitting of Lagos city into the present day seven Local Government Areas (LGAs), and an addition of other towns (which now make up 13 LGAs) from the then Western Region, to form the state. In social science, the term built environment refers to the man-made surroundings that provide the setting for human activity, ranging in scale from buildings and parks. It has been defined as "the humanitarian-made space in which people live, work, and recreate on a day-to-day basis." The "built environment encompasses places and spaces created or modified by people including buildings, parks, and transportation systems." In recent years, public health research has expanded the definition of "built environment" to include healthy food access, community gardens,mental health, "walkability" and "bikeability." A conurbation is a region comprising a number of cities, large towns, and other urban areas that, through population growth and physical expansion, have merged to form one continuous urban or industrially developed area. In most cases, a conurbation is a polycentric urbanised area, in which transportation has developed to link areas to create a single urban labour market or travel to work area. Cameroon, officially the Republic of Cameroon, is a country in Central Africa. It is bordered by Nigeria to the west; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon, and the Republic of the Congo to the south. Cameroon's coastline lies on the Bight of Bonny, part of the Gulf of Guinea and the Atlantic Ocean.
