Regions Of Namibia
Namibia uses regions as its first-level subnational administrative divisions. Since 2013, it has 14 regions which in turn are subdivided into Constituencies of Namibia, 121 constituencies. Upon Independence of Namibia, Namibian independence, the pre-existing subdivisions from the South African administration were taken over. Since then, demarcations and numbers of regions and constituencies of Namibia are tabled by delimitation commissions and accepted or declined by the National Assembly of Namibia, National Assembly. In 1992, the ''1st Delimitation Commission'', chaired by Judge President Johan Strydom, proposed that Namibia should be divided into 13 regions. The suggestion was approved in the lower house, The National Assembly. In 2014, the ''4th Delimitation Commission'' amended the number of regions to fourteen. The most urbanised and economically active regions are the Khomas and Erongo region, with Khomas home to the capital, Windhoek, and Erongo home to Walvis Bay and ...

German Colonial Empire
The German colonial empire () constituted the overseas colonies, dependencies, and territories of the German Empire. Unified in 1871, the chancellor of this time period was Otto von Bismarck. Short-lived attempts at colonization by Kleinstaaterei, individual German states had occurred in preceding centuries, but Bismarck resisted pressure to construct a colonial empire until the Scramble for Africa in 1884. Claiming much of the remaining uncolonized areas of Africa, Germany built the third-largest colonial empire at the time, after the British Empire, British and Second French colonial empire, French. The German colonial empire encompassed parts of Africa and Oceania. Germany lost control of most of its colonial empire at the beginning of the World War I, First World War in 1914, but some German forces held out in German East Africa until the end of the war. After the Armistice of 11 November 1918, German defeat in World , Germany's colonial empire was officially confiscated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish River Canyon
The Fish River Canyon (Afrikaans: ''Visrivier Canyon'' or'' Visrivier Kuil'', ) is located in the south of Namibia. It is the largest canyon in Africa, and the second most visited tourist attraction in Namibia.Matador Trips - 27 of the deepest canyons you can experience. It features a gigantic ravine, in total about long, up to 27 km wide and in places almost 550 meters deep. The Fish River is the longest interior river in Namibia. It cuts deep into the plateau which today is dry, stony and sparsely covered with hardy drought-resistant plants. The river flows intermittently, usually flooding in late summer; the rest of the year it becomes a chain of long narrow pools. The hot springs resort of ǀAi-ǀAis is situated at the lower end of the Fish River Canyon. Public view points can be visited near Hobas, a camp site 70 km north of ǀAi-ǀAis.

Barbel (fish)
Barbels are a group of carp-like freshwater fish, almost all of the genus ''Barbus''. They are usually found in gravel and rocky-bottomed moderate-flowing rivers with high dissolved oxygen content, known as the ''European river zonation#Barbel zone, Barbel zone''. A typical adult barbel can range from in length and weigh between and , depending on species. The name barbel derived from the Latin ''barba'', meaning beard, a reference to the two pairs of barbel (anatomy), barbels, a longer pair pointing forwards and slightly down positioned, on the side of the mouth. Fish described as barbels by English-speaking people may not be known as barbels in their native language, although the root of the word may be similar. For instance, the Mediterranean barbel (''Barbus meridionalis'') is known as ''barbeau méridional'' or ''barbeau truité'' in France, but also as ''drogan'', ''durgan'', ''tourgan'', ''turquan'' and ''truitat''. Europe ''Barbus barbus'', is found throughout northern a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Zambezi Yellowfish
The Upper Zambezi yellowfish, ''Labeobarbus codringtonii'', is commonly found throughout the Zambezi and Okavango Rivers in Southern Africa. They prefer fast flowing water over cobble and rocky bottoms where they predominantly feed on aquatic insects and crustacean Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are traditionally a part of the subphylum Crustacea (), a large, diverse group of mainly aquatic arthrop ...s. Their exaggerated fins help them manoeuvre in the fast water and they are powerful swimmers. The Zambezi yellowfish is highly sought after by sport anglers and fly fishing is the preferred method of catching them.

Rheumatism
Rheumatism or rheumatic disorders are conditions causing chronic, often intermittent pain affecting the joints or connective tissue. Rheumatism does not designate any specific disorder, but covers at least 200 different conditions, including arthritis and "non-articular rheumatism", also known as "regional pain syndrome" or "soft tissue rheumatism". There is a close overlap between the term soft tissue disorder and rheumatism. Sometimes the term "soft tissue rheumatic disorders" is used to describe these conditions. The term "Rheumatic Diseases" is used in MeSH to refer to connective tissue disorders. The branch of medicine devoted to the diagnosis and therapy of rheumatism is called rheumatology. Types Many rheumatic disorders of chronic, intermittent pain (including joint pain, neck pain or back pain) have historically been caused by infectious diseases. Their etiology was unknown until the 20th century and not treatable. Postinfectious arthritis, also known as react ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Treaty
A treaty is a formal, legally binding written agreement between sovereign states and/or international organizations that is governed by international law. A treaty may also be known as an international agreement, protocol, covenant, convention, pact, or exchange of letters, among other terms; however, only documents that are legally binding on the parties are considered treaties under international law. Treaties may be bilateral (between two countries) or multilateral (involving more than two countries). Treaties are among the earliest manifestations of international relations; the first known example is a border agreement between the Sumerian city-states of Lagash and Umma around 3100 BC. International agreements were used in some form by most major civilizations and became increasingly common and more sophisticated during the early modern era. The early 19th century saw developments in diplomacy, foreign policy, and international law reflected by the widespread use of tre ...

Conservation Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural or cultural values. Protected areas are those areas in which human presence or the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas and transboundary protected areas across multiple borders. As of 2016, there are over 161,000 protected areas representing about 17 percent of the world's land surface area (excluding Antarctica). For waters under national jurisdiction beyond inland waters, there are 14,688 Marine Protected Areas (MPAs), covering approximately 10.2% of coastal and marine areas and 4.12% of global ocean areas. In contrast, only 0.25% of the world's oceans beyond national jurisdiction are covered by MPAs. In recent years, the 30 by 30 initiative has targeted to protect 30% of ocean territory and 30% of land territory worldwide by 2030; t ...
