River Opa
The Opa River is a significant watercourse in southwestern Nigeria, flowing through the city of Ile-Ife and the Obafemi Awolowo University campus. It is a tributary of the Shasha River and plays a crucial role in the hydrological landscape of the region. Geography and geomorphology The Opa River is situated in southwestern Nigeria, flowing through the city of Ile-Ife and the Obafemi Awolowo University campus. It spans approximately 40 km (25 mi) in length, originating from the Ile-Ife hills. The river's location within the tropical region influences its hydrological characteristics. Geologically, the Opa River's catchment area is underlain by crystalline basement rocks, comprising granite, gneiss, and schist. This complex geological setting shapes the river's geomorphic features. The river's course is characterized by a mix of NE-SW and NW-SE trends, reflecting the influence of differing lithologies and tectonic activities. The Opa River's geomorphic features include a 4 ...

Obafemi Awolowo University
Obafemi Awolowo University (OAU) is a federal university in Ile-Ife, Osun State, Nigeria. The university was founded in 1961 and classes commenced in October 1962 as the University of Ife by the regional government of Western Nigeria, which was led by Samuel Ladoke Akintola. It was renamed "Obafemi Awolowo University" on 12 May 1987, so by the Ibrahim Badamasi Babangida led military administration, in honour of Obafemi Awolowo (1909–1987), the first premier of the Western Region of Nigeria, who initially thought of the idea of establishing the university. History In 1951, with the adoption of a new Constitution of Nigeria, constitution, major changes were made to elected legislators and regional Premiers in the regions. Because they saw education as a key driver of change and development, the new regional administrations gave an extension of basic and secondary education priority. A commission was established by the Federal Minister of Education in 1959 to study the nation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tributary
A tributary, or an ''affluent'', is a stream or river that flows into a larger stream (''main stem'' or ''"parent"''), river, or a lake. A tributary does not flow directly into a sea or ocean. Tributaries, and the main stem river into which they flow, drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean, another river, or into an endorheic basin. The Irtysh is a chief tributary of the Ob (river), Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shasha River
The Shasha River or Sasa River (Yoruba language, Yoruba: Odo Shasha) is a river in Lagos, Ogun State, Ogun and Osun State, Osun States in Nigeria. The landscape varies from rainforest in the north to Mangrove, mangrove swamps in the south. Course The Shasha River is a river in southwestern Nigeria that flows through the states of Osun, Ogun, and Lagos. It originates from Shasha village in the Ifẹ, Ife region of Osun State and flows southwest for approximately 50 kilometers before emptying into the Lekki Lagoon. The river passes through several towns, including Ipetumodu, Odeomu, and Edunabon, before reaching its mouth at the Lekki Lagoon. Along its course, the Shasha River drains a significant portion of the southwestern Nigerian landscape, including the Osun River basin and the campus of Obafemi Awolowo University. The river also passes through several villages, including Eyentanle, Kinkinyiun, Odeyinka, Ogbaagba, Sunmoge, and others, providing water and supporting the livelihoo ...

Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...

Urbanization
Urbanization (or urbanisation in British English) is the population shift from Rural area, rural to urban areas, the corresponding decrease in the proportion of people living in rural areas, and the ways in which societies adapt to this change. It can also mean population growth in urban areas instead of rural ones. It is predominantly the process by which towns and City, cities are formed and become larger as more people begin to live and work in central areas. Although the two concepts are sometimes used interchangeably, urbanization should be distinguished from Urban sprawl, urban growth. Urbanization refers to the ''proportion'' of the total national population living in areas classified as urban, whereas urban growth strictly refers to the ''absolute'' number of people living in those areas. It is predicted that by 2050, about 64% of the developing world and 86% of the developed world will be urbanized. This is predicted to generate artificial scarcities of land, lack of dr ...

Potable Water
Drinking water or potable water is water that is safe for ingestion, either when drunk directly in liquid form or consumed indirectly through food preparation. It is often (but not always) supplied through taps, in which case it is also called tap water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. For those who work in a hot climate, up to a day may be required. About 1 to 2 billion people lack safe drinking water. Water can carry vectors of disease and is a major cause of death and illness worldwide. Developing countries are most affected by unsafe drinking water. Sources Potable water is available in almost all populated areas of the world, although it may be expensive, and the supply may not always be sustainable. Sources where drinking water is commo ...

Climate Change
Present-day climate change includes both global warming—the ongoing increase in Global surface temperature, global average temperature—and its wider effects on Earth's climate system. Climate variability and change, Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global temperatures is Scientific consensus on climate change, driven by human activities, especially fossil fuel burning since the Industrial Revolution. Fossil fuel use, Deforestation and climate change, deforestation, and some Greenhouse gas emissions from agriculture, agricultural and Environmental impact of concrete, industrial practices release greenhouse gases. These gases greenhouse effect, absorb some of the heat that the Earth Thermal radiation, radiates after it warms from sunlight, warming the lower atmosphere. Carbon dioxide, the primary gas driving global warming, Carbon dioxide in Earth's atmosphere, has increased in concentratio ...

Fishing
Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment (Freshwater ecosystem, freshwater or Marine ecosystem, marine), but may also be caught from Fish stocking, stocked Body of water, bodies of water such as Fish pond, ponds, canals, park wetlands and reservoirs. Fishing techniques include trawling, Longline fishing, longlining, jigging, Fishing techniques#Hand-gathering, hand-gathering, Spearfishing, spearing, Fishing net, netting, angling, Bowfishing, shooting and Fish trap, trapping, as well as Destructive fishing practices, more destructive and often Illegal, unreported and unregulated fishing, illegal techniques such as Electrofishing, electrocution, Blast fishing, blasting and Cyanide fishing, poisoning. The term fishing broadly includes catching aquatic animals other than fish, such as crustaceans (shrimp/lobsters/crabs), shellfish, cephalopods (octopus/squid) and echinoderms (starfish/sea urchins). The term is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waste Management
Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms. Waste can either be solid, liquid, or gases and each type has different methods of disposal and management. Waste management deals with all types of waste, including industrial, chemical, municipal, organic, biomedical, and radioactive wastes. In some cases, waste can pose a threat to human health. Health issues are associated with the entire process of waste management. Health issues can also arise indirectly or directly: directly through the handling of solid waste, and indirectly through the consumption of water, soil, and food. Waste is produced by human activity, for example, the extraction and processing of raw mater ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
