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.

ǀAi-ǀAis/Richtersveld Transfrontier Park
The ǀAi-ǀAis/Richtersveld Transfrontier Park is a peace park straddling the border between South Africa and Namibia. It was formed in 2003 by combining the Namibian '' ǀAi-ǀAis Hot Springs Game Park'' and the South African ''Richtersveld National Park''. Most of the South African part of the park forms part of the buffer zone of the Richtersveld Cultural and Botanical Landscape World Heritage Site, which measures . The Fish River Canyon, the largest canyon in Africa, is located in the park. A memorandum of understanding was signed on 17 August 2003 by the presidents of South Africa and Namibia, which formalised the establishment of the park. , Ai-, Ais is Khoekhoe for ''fire-fire'', meaning 'hot as fire' or 'scalding hot', after the hot springs of the same name.

Richtersveld
The Richtersveld is a desert landscape characterised by rugged kloofs and high mountains, situated in the north-western corner of South Africa’s Northern Cape province. It is full of changing scenery from flat, sandy, coastal plains, to craggy sharp mountains of volcanic rock and the lushness of the Orange River, which forms the border with neighboring Namibia. The area ranges in altitude from sea level, to at Cornellberg. Located in the north-western side of the Northern Cape province in South Africa, the Richtersveld is regarded as the only arid biodiversity hotspot on earth and the majority of the area is inscribed on UNESCO's World Heritage List due to its cultural values. The Nama people of Richtersveld claimed title to their traditional land and set aside this conservancy for future research and tourism. The northern part of the area was proclaimed in 1991 after 18 years of negotiations between the National Parks Board and the local Nama people who continue to live ...

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 ...

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 ...

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 ...
