Hirgigo
Arkiko (, Afar and Saho: ''Hirg-Higo'', alternately Archigo, Arqiqo, Ercoco, Hirgigo, Hargigo or Harkiko) historically known as Dokono is a town in the Northern Red Sea region of Eritrea. Situated on the Red Sea, it lies on the mainland across from the city of Massawa. Etymology Arkiki or known by the locals Saho tribe; the clans of Dasamo, as Hirg-Higo. The clan of Dasamo are the inhabitant of this area, it is also known by the name Docono, from either the Saho or Afar word for "elephant". The meaning of Higo is legend of legends in Saho language. Richard Pankhurst explains this etymology to the importance of the ivory trade to Hirg-Higo or known as Arkiko. History Arkiko and the nearby island port of Massawa handled most of northern Ethiopia's foreign trade at this time. According to the Portuguese, exports in the early 16th century consisted of gold and ivory, as well as honey, wax, and slaves. Despite their economic interdependence, politically the two ports were often di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarsa Dengel
Sarsa Dengel ( ; 1550 – 4 October 1597), also known as Sarsa the Great, was Emperor of Ethiopia, and a member of the Solomonic dynasty. His throne name was throne name Malak Sagad I (መለክ ሰገድ ). He is considered one of the greatest warrior-kings of the Ethiopian Empire. Sarsa Dengel, the son of Emperor Menas and Empress Admas Mogasa, was elected king at the age of 14. As ruler, he faced several revolts and moved the empire's center from Shewa to Begemder. Sarsa Dengel fought against the Ottomans, defeating regional ruler Bahr Negus Yeshaq and Adal Sultan Muhammad V. He also repelled the Turkish invaders in Debarwa and Hirgigo. In addition, Sarsa Dengel led campaigns against the Oromo tribes who were migrating northward, successfully pushing them back. Despite his military successes, historians argue that his focus on northern campaigns instead of addressing the Oromo expansion in the south ultimately led to the decline of the Ethiopian Empire.

Red Sea
The Red Sea is a sea inlet of the Indian Ocean, lying between Africa and Asia. Its connection to the ocean is in the south, through the Bab-el-Mandeb Strait and the Gulf of Aden. To its north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez—leading to the Suez Canal. It is underlain by the Red Sea Rift, which is part of the Great Rift Valley. The Red Sea has a surface area of roughly , is about long, and wide at its widest point. It has an average depth of , and in the central Suakin Trough, it reaches its maximum depth of . Approximately 40% of the Red Sea is quite shallow at less than deep and about 25% is less than deep. The extensive shallow shelves are noted for their marine life and corals. More than 1,000 invertebrate species and 200 types of soft and hard coral live in the sea. The Red Sea is the world's northernmost tropical sea and has been designated a Global 200 ecoregion.

Eritrean War Of Independence
The Eritrean War of Independence was an War, armed conflict and insurgency aimed at achieving self-determination and independence for Eritrea from Ethiopian rule. Starting in 1961, Eritrean insurgents engaged in guerrilla warfare to liberate Eritrea Province from the control of the Ethiopian Empire under Haile Selassie and later the Derg under Mengistu Haile Mariam, Mengistu. Their efforts ultimately succeeded in 1991 with the fall of the Derg regime. Eritrea was an Italian Eritrea, Italian colony from the 1880s until the Italians were defeated by the Allies in World War II in 1941. Afterward, Eritrea briefly became a Italian Eritrea#British Military Administration and the end of the colony, British protectorate until 1951. The United Nations convened after the war to decide Eritrea's future, eventually voting in favor of a federation between Eritrea and Ethiopia. As a result, Eritrea became a constituent state of the Federation of Ethiopia and Eritrea. The federation was int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Regions Of Eritrea
The regions of Eritrea are the primary geographical divisions through which Eritrea is administered. Six in total, they include the Maekel Region, Central, Anseba Region, Anseba, Gash-Barka Region, Gash-Barka, Debub Region, Southern, Northern Red Sea Region, Northern Red Sea and Southern Red Sea Region, Southern Red Sea regions. At the time of independence in 1993 Eritrea was arranged into ten Provinces of Eritrea, provinces. These provinces were similar to the nine provinces operating during the colonial period. In 1996, these were consolidated into six regions (''zobas''). Gash-Barka Region is the largest and sparsely populated region and is called the "bread-basket". The People's Front for Democracy and Justice or PFDJ (originally Eritrean People's Liberation Front) rules the country and its regions as a Single-party state, single-party totalitarian government. The Elections in Eritrea, regional and local elections are conducted on a periodic basis on a restricted framework. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosphorus
Phosphorus is a chemical element; it has Chemical symbol, symbol P and atomic number 15. All elemental forms of phosphorus are highly Reactivity (chemistry), reactive and are therefore never found in nature. They can nevertheless be prepared artificially, the two most common allotropes being white phosphorus and red phosphorus. With as its only stable isotope, phosphorus has an occurrence in Earth's crust of about 0.1%, generally as phosphate rock. A member of the pnictogen family, phosphorus readily forms a wide variety of organic compound, organic and inorganic compound, inorganic compounds, with as its main oxidation states +5, +3 and −3. The isolation of white phosphorus in 1669 by Hennig Brand marked the scientific community's first discovery since Antiquity of an element. The name phosphorus is a reference to the Phosphorus (morning star), god of the Morning star in Greek mythology, inspired by the faint glow of white phosphorus when exposed to oxygen. This property is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrogen
Nitrogen is a chemical element; it has Symbol (chemistry), symbol N and atomic number 7. Nitrogen is a Nonmetal (chemistry), nonmetal and the lightest member of pnictogen, group 15 of the periodic table, often called the Pnictogen, pnictogens. It is a common element in the universe, estimated at Abundance of the chemical elements, seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element chemical bond, bond to form N2, a colourless and odourless diatomic molecule, diatomic gas. N2 forms about 78% of Atmosphere of Earth, Earth's atmosphere, making it the most abundant chemical species in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772 and independently by Carl Wilhelm Scheele and Henry Cavendish at about the same time. The name was suggested by French chemist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overgrazing
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds. Degrading land, emissions from animal agriculture and reducing the biomass in a ecosystem contribute directly to climate change between grazing events. Successful planned grazing strategies have been in support of the American bison of the Great Plains, or migratory wildebeest of the African savannas, or by holistic planned grazing.

Mangrove
A mangrove is a shrub or tree that grows mainly in coastal saline water, saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal rivers. They have particular adaptations to take in extra oxygen and remove salt, allowing them to tolerate conditions that kill most plants. The term is also used for tropical coastal vegetation consisting of such species. Mangroves are taxonomically diverse due to convergent evolution in several plant families. They occur worldwide in the tropics and subtropics and even some temperate coastal areas, mainly between latitudes 30° N and 30° S, with the greatest mangrove area within 5° of the equator. Mangrove plant families first appeared during the Late Cretaceous to Paleocene epochs and became widely distributed in part due to the plate tectonics, movement of tectonic plates. The oldest known fossils of Nypa fruticans, mangrove palm date to 75 million years ago. Mangroves are salt-tolerant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electricity Generation
Electricity generation is the process of generating electric power from sources of primary energy. For electric utility, utilities in the electric power industry, it is the stage prior to its Electricity delivery, delivery (Electric power transmission, transmission, Electric power distribution, distribution, etc.) to end users or its Grid energy storage, storage, using for example, the Pumped-storage hydroelectricity, pumped-storage method. Consumable electricity is not freely available in nature, so it must be "produced", transforming other forms of energy to electricity. Production is carried out in power stations, also called "power plants". Electricity is most often generated at a power plant by electromechanical electric generator, generators, primarily driven by heat engines fueled by combustion or nuclear fission, but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power. There are ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
