Ogunpa River
The Ogunpa River river system is a third-order stream with a channel length of and a drainage basin covering draining the densely populated eastern part of Ibadan, Nigeria. The city of Ibadan in southwestern Nigeria (7º23’ N, 3º5’ E) is the largest urban centre in Africa south of the Sahara. Ogunpa River is known to contain 49 species of zooplankton. Public safety Household waste is known to be dumped along the path of the Ogunpa. This sometimes results in disastrous consequences. In 1960, more than 1,000 residents were rendered homeless when the Ogunpa River exceeded its banks. More than 500 houses were damaged in 1963 when the river again flooded the city. In 1978, official record confirmed that 32 bodies were retrieved from the ruins of the flood and more than 100 houses were destroyed. Disaster It was, however, the flood of August 31, 1980 that gave the Ogunpa national and international notoriety. After about 10 hours of heavy downpour recorded as four times heavier ...

Stream
A stream is a continuous body of water, body of surface water Current (stream), flowing within the stream bed, bed and bank (geography), banks of a channel (geography), channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent river, intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighting (streams), daylighted subterranean river, subterranean water, and surfaced groundwater (Spring (hydrology), spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes th ...

Residency (domicile)
Domicile is relevant to an individual's "personal law," which includes the law that governs a person's status and their property. It is independent of a person's nationality. Although a domicile may change from time to time, a person has only one domicile, or residence, at any point in their life, no matter what their circumstances. Domicile is distinct from habitual residence, where there is less focus on future intent. As domicile is one of the connecting factors ordinarily used in common law legal systems, a person can never be left without a domicile and a domicile is acquired by everyone at birth. Generally domicile can be divided into domicile of origin, domicile of choice, and domicile by operation of law (also known as domicile of dependency). When determining the domicile of an individual, a court applies its own law and understanding of what domicile is. In some common-law countries, such as Australia and New Zealand, the concept of domicile has been subject to statutory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naira
The naira (sign: ₦; code: NGN) is the currency of Nigeria. One naira is divided into 100 ''kobo''. The Central Bank of Nigeria (CBN) is the sole issuer of legal tender money throughout the Federal Republic of Nigeria. It controls the volume of money supplied in the economy in order to ensure monetary and price stability. The Currency Operations Department of the CBN is in charge of currency management, through the designs, procurement, distribution and supply, processing, reissue and disposal or disintegration of bank notes and coins. History The naira was introduced on 1 January 1973, replacing the Nigerian pound at a rate of £1 = ₦2 naira. The coins of the new currency were the first coins issued by an independent Nigeria, as all circulating coins of the Nigerian pound were all struck by the colonial government of the Federation of Nigeria in 1959, with the name of Queen Elizabeth II on the obverse. This also made Nigeria the last country in the world to abandon the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oyo State
Oyo State is an inland state in southwestern Nigeria. Its capital is Ibadan, the third most populous city in the country and formerly the second most populous city in Africa. Oyo State is bordered to the north by Kwara State, to the east by Osun State, and to the southwest by Ogun State and the Republic of Benin. With a projected population of 7,840,864 in 2016, Oyo State is the fifth most populous in the Nigeria. The vast majority of Oyo State residents are Yoruba, and the Yoruba language remains dominant. Nicknamed the "Pace Setter State", present-day Oyo State sits on territory formerly ruled by various kingdoms and empires. The Oyo Empire was a powerful Yoruba empire that ruled in much of the area from c. 1300 to 1896. Built in the 1830s, modern city of Oyo is considered a remnant of the imperial era, being referred to as "New Ọyọ" (''Ọ̀yọ́ Àtìbà'') to distinguish itself from the former capital to the north, 'Old Oyo' (''Ọ̀yọ́-Ilé''). The Alaafin of Oyo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Channelization (rivers)
River engineering is a discipline of civil engineering which studies human intervention in the course, characteristics, or flow of a river with the intention of producing some defined benefit. People have intervened in the natural course and behaviour of rivers since before recorded history—to manage the water resources, to protect against flooding, or to make passage along or across rivers easier. Since the Yuan Dynasty and Ancient Roman times, rivers have been used as a source of hydropower. From the late 20th century, the practice of river engineering has responded to environmental concerns broader than immediate human benefit. Some river engineering projects have focused exclusively on the restoration or protection of natural characteristics and habitats. Hydromodification encompasses the systematic response to alterations to riverine and non-riverine water bodies such as coastal waters (estuaries and bays) and lakes. The U.S. Environmental Protection Agency (EPA) has de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nigerian
Nigerians or the Nigerian people are citizens of Nigeria or people with ancestry from Nigeria. The name Nigeria was taken from the Niger River running through the country. This name was allegedly coined in the late 19th century by British journalist Flora Shaw, who later married Baron Frederick Lugard, a British colonial administrator. ''Nigeria'' is composed of various ethnic groups and Culture, cultures and the term Nigerian refers to a citizenship-based civic nationality. Nigerians derive from over 250 ethnic groups and languages.Toyin Falola. ''Culture and Customs of Nigeria''. Westport, Connecticut, USA: Greenwood Press, 2001. p. 4. Though there are multiple ethnic groups in Nigeria, economic factors result in significant mobility of Nigerians of multiple ethnic and religious backgrounds to reside in territories in Nigeria that are outside their ethnic or religious background, resulting in the mixing of the various ethnic and religious groups, especially in Nigeria's cities ...

Flood
A flood is an overflow of water ( or rarely other fluids) that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health. Human changes to the environment often increase the intensity and frequency of flooding, for example land use changes such as deforestation and removal of wetlands, changes in waterway course or flood controls such as with levees, and larger environmental issues such as climate change and sea level rise. In particular climate change's increased rainfall and extreme weather events increases the severity of other causes for flooding, resulting in more intense floods and increased flood risk. Flooding may occur as an overflow of water from water bodies, such as a river, lake, or ocean, in which the water overtops or breaks levees, resulting ...

Homeless
Homelessness or houselessness – also known as a state of being unhoused or unsheltered – is the condition of lacking stable, safe, and adequate housing. People can be categorized as homeless if they are: * living on the streets, also known as rough sleeping (primary homelessness); * moving between temporary shelters, including houses of friends, family, and emergency accommodation (secondary homelessness); and * living in private boarding houses without a private bathroom or security of tenure (tertiary homelessness). * have no permanent house or place to live safely * Internally Displaced Persons, persons compelled to leave their places of domicile, who remain as refugees within their country's borders. The rights of people experiencing homelessness also varies from country to country. United States government homeless enumeration studies also include people who sleep in a public or private place, which is not designed for use as a regular sleeping accommodation for hum ...

Waste
Waste (or wastes) are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero. Examples include municipal solid waste (household trash/refuse), hazardous waste, wastewater (such as sewage, which contains bodily wastes ( feces and urine) and surface runoff), radioactive waste, and others. Definitions What constitutes waste depends on the eye of the beholder; one person's waste can be a resource for another person. Though waste is a physical object, its generation is a physical and psychological process. The definitions used by various agencies are as below. United Nations Environment Program According to the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes a ...

Household
A household consists of two or more persons who live in the same dwelling. It may be of a single family or another type of person group. The household is the basic unit of analysis in many social, microeconomic and government models, and is important to economics and inheritance. Household models include families, blended families, shared housing, group homes, boarding houses, houses of multiple occupancy (UK), and single room occupancy (US). In feudal societies, the royal household and medieval households of the wealthy included servants and other retainers. Government definitions For statistical purposes in the United Kingdom, a household is defined as "one person or a group of people who have the accommodation as their only or main residence and for a group, either share at least one meal a day or share the living accommodation, that is, a living room or sitting room".

Zooplankton
Zooplankton are the animal component of the planktonic community ("zoo" comes from the Greek word for ''animal''). Plankton are aquatic organisms that are unable to swim effectively against currents, and consequently drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton, which are the plant component of the plankton community ("phyto" comes from the Greek word for ''plant''). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding). This means zooplankton cannot manufacture their own food but must eat other plants or animals instead — in particular they eat phytoplankton. Zooplankton are generally larger than phytoplankton, most are microscopic, but some (such as jellyfish) are macroscopic and can be seen with the naked eye. Many protozoans (single-celled protists that prey on other microscopic life) are zooplankton, including zooflagellates, fo ...
