Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become arid. It is the spread of arid areas caused by a variety of factors, such as climate change and overexploitation of soil as a result of human activity.
Acorus calamus is a species of flowering plant with psychoactive chemicals. It is a tall wetland monocot of the family Acoraceae, in the genus Acorus. Although used in traditional medicine over centuries to treat digestive disorders and pain, there is no clinical evidence for its safety or efficacy – and ingested calamus may be toxic – leading to its commercial ban in the United States.
Dioscorea alata, also known as purple yam, ube, or greater yam, among many other names, is a species of yam. The tubers are usually a vivid violet-purple to bright lavender in color, but some range in color from cream to plain white. It is sometimes confused with taro and the Okinawa sweet potato, although D. alata is also grown in Okinawa, where it is known as beniimo (紅芋). With its origins in the Asian tropics, D. alata has been known to humans since ancient times.
The Hoggar Mountains are a highland region in the central Sahara in southern Algeria, along the Tropic of Cancer. The mountains cover an area of approximately 550,000 km.
Adansonia is a genus made up of eight species of medium-to-large deciduous trees known as baobabs. They are placed in the Malvaceae family, subfamily Bombacoideae. They are native to Madagascar, mainland Africa, and Australia. The trees have also been introduced to other regions such as Asia. The generic name honours Michel Adanson, the French naturalist and explorer who described Adansonia digitata. The baobab is also known as the "upside down tree", a name that originates from several myths. They are among the most long-lived of vascular plants and have large flowers that are reproductive for a maximum of 15 hours. The flowers open around dusk, opening so quickly that movement can be detected by the naked eye, and are faded by the next morning. The fruits are large, oval to round and berry-like and hold kidney-shaped seeds in a dry, pulpy matrix.
A Flora is a book or other work which describes the plant species occurring in an area or time period, often with the aim of allowing identification. The term is usually capitalized to distinguish it from the use of "flora" to mean the plants rather than their descriptions. Some classic and modern Floras are listed below.
Virunga National Park is a national park in the Albertine Rift Valley in the eastern part of the Democratic Republic of the Congo. It was created in 1925. In elevation, it ranges from 680 m (2,230 ft) in the Semliki River valley to 5,109 m (16,762 ft) in the Rwenzori Mountains. From north to south it extends approximately 300 km (190 mi), largely along the international borders with Uganda and Rwanda in the east. It covers an area of 8,090 km2 (3,120 sq mi).
Streptophyta, informally the streptophytes, is a clade of plants. The composition of the clade varies considerably between authors, but the definition employed here includes land plants and all green algae except the Chlorophyta and the more basal Prasinodermophyta.
Hibiscus tiliaceus, commonly known as the sea hibiscus or coast cottonwood, is a species of flowering tree in the mallow family, Malvaceae, with a pantropical distribution along coastlines. It has also been introduced to Florida and New Zealand. It has been debated whether this species is native or introduced to Hawaii.
The W National Park or W Regional Park is a major national park in West Africa around a meander in the River Niger shaped like the letter W. The park includes areas of the three countries Niger, Benin and Burkina Faso, and is governed by the three governments. Until 2008, the implementation of a regional management was supported by the EU-funded project ECOPAS. The three national parks operate under the name W Transborder Park.. The section of W National Park lying in Benin, measuring over 8,000 km2 (3,100 sq mi), came under the full management of African Parks in June 2020. In Benin, W National Park is contiguous with Pendjari National Park which is also under the management of African Parks.
Striga, commonly known as witchweed, is a genus of parasitic plants that occur naturally in parts of Africa, Asia, and Australia. It is currently classified in the family Orobanchaceae, although older classifications place it in the Scrophulariaceae. Some species are serious pathogens of cereal crops, with the greatest effects being in savanna agriculture in Africa. It also causes considerable crop losses in other regions, including other tropical and subtropical crops in its native range and in the Americas. The generic name derives from Latin strī̆ga, "witch."
The Convention on the Protection and Promotion of the Diversity of Cultural Expressions is an international treaty adopted in October 2005 in Paris during the 33rd session of the General Conference of the United Nations Educational, Scientific and Cultural Organization (UNESCO). Building on the UNESCO Universal Declaration on Cultural Diversity, it allows states to protect cultural diversity by promoting and defending their own cultural industries. It also establishes international co-operation to help protect the cultural industries of developing countries, including the creation of an International fund for Cultural Diversity.
Glaucium flavum, the yellow horned poppy, yellow hornpoppy or sea poppy, is a summer flowering plant in the family Papaveraceae. It is native to Europe, Northern Africa, Macaronesia and temperate zones in Western Asia. The plant grows on the seashore and is never found inland. All parts of the plant, including the seeds, are toxic. It is classed as a noxious weed in some areas of North America, where it is an introduced species. It is grown in gardens as a short-lived perennial but usually grown as a biennial.
Rhizoxin is an antimitotic agent with anti-tumor activity. It is isolated from a pathogenic plant fungus which causes rice seedling blight.
Eribulin, sold under the brand name Halaven, is an anticancer medication used to treat breast cancer and liposarcoma.
Antiaris toxicaria is a tree in the mulberry and fig family, Moraceae. It is the only species currently recognized in the genus Antiaris. The genus Antiaris was at one time considered to consist of several species, but is now regarded as just one variable species which can be further divided into five subspecies. One significant difference within the species is that the size of the fruit decreases as one travels from Africa to Polynesia. Antiaris has a remarkably wide distribution in tropical regions, occurring in Australia, tropical Asia, tropical Africa, Indonesia, the Philippines, Tonga, and various other tropical islands. Its seeds are spread by various birds and bats, and it is not clear how many of the populations are essentially invasive. The species is of interest as a source of wood, bark cloth, and pharmacological or toxic substances.
Canada–Democratic Republic of the Congo relations are the bilateral relations between Canada and the Democratic Republic of the Congo. Canada has an embassy in Kinshasa and D.R. Congo has an embassy in Ottawa.
Detarium microcarpum, commonly known as sweet detar, sweet dattock or tallow tree, is an underutilized species of tree legume that grows naturally in the drier regions of West and Central Africa. It has a wide range of uses due to its medicinal properties, edible fruit and hardwood, which is used as fuel. This makes it valuable and appreciated by local communities, but further research and effort are needed for its domestication.
Iris serotina is a species in the genus Iris, it is also in the subgenus Xiphium. It is a bulbous perennial from southern Europe, found in Spain and Morocco.
