Algerian Green Dam
The Algerian Green Dam refers to a project initiated in Algeria in the 1960s to plant millions of trees to stop desertification, specifically to prevent the northward advancement of the Sahara Desert. The project has progressed and evolved through the 1970s, 80s, 90s, and into the 2000s. The green barrier is located in the pre-Saharan area in Algeria. It stretches between the Moroccan border in the West to the Tunisian border in the East, covering a total distance of approximately 1000 km. The barrier's width ranges from approximately 20 km between isohyets of 300 mm in the North and 200 mm in the South of Algeria. The project's objective is to recover the extent of the already existing forest to stop the sand expansion. Two types of vegetation were planted: Aleppo pine (Pinus halepensis), which grows easily in this region, and Alfa (Stipa tenacissima). History The risk of desertification threatens arid and semi-arid regions throughout the world. Population growth, urbanizat ...

Desertification
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 increasingly 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. Throughout geological history, the development of deserts has occurred naturally. In recent times, the potential influences of human activity, improper land management, deforestation and climate change on desertification is the subject of many scientific investigations. Definitions of words As recently as 2005, considerable controversy existed over the proper definition of the term "desertification." Helmut Geist (2005) identified more than 100 formal definitions. The most widely acceptedGeist (2005)p. 2/ref> of these was that of the Princeton University Dictionary which defined it as "the process of fertile land ''transforming into ...

Pinus Halepensis
''Pinus halepensis'', commonly known as the Aleppo pine, also known as the Jerusalem pine, is a pine native to the Mediterranean region. Description ''Pinus halepensis'' is a small to medium-sized tree, tall, with a trunk diameter up to , exceptionally up to . The bark is orange-red, thick, and deeply fissured at the base of the trunk, and thin and flaky in the upper crown. The leaves ('needles') are very slender, long, distinctly yellowish green, and produced in pairs (rarely a few in threes). The cones are narrow conic, long and broad at the base when closed, green at first, ripening glossy red-brown when 24 months old. They open slowly over the next few years, a process quickened if they are exposed to heat such as in forest fires. The cones open wide to allow the seeds to disperse. The seeds are long, with a wing, and are wind- dispersed.Nahal, I. (1962). Le Pin d'Alep (''Pinus halepensis'' Miller). Étude taxonomique, phytogéographique, écologique et sylvicole. '' ...

Houari Boumédiène
Houari Boumédiène ( ar, ; ALA-LC: ''Hawwārī Būmadyan''; born Mohammed Ben Brahim Boukherouba; 23 August 1932 – 27 December 1978) was an Algerian politician and army colonel who served as Chairman of the Revolutionary Council of Algeria from 19 June 1965 until 12 December 1976 and thereafter as the second President of Algeria until his death in 1978. Born in Guelma, he was educated at the Islamic Institute in Constantine. He joined the National Liberation Front in 1955 and adopted the nom de guerre Houari Boumediene. He received the rank of colonel and in 1960 became the commander of the military wing of the FLN. President Ahmed Ben Bella appointed him Minister of Defense in 1961. He did not agree with Ben Bella's reforms, and later overthrew him in a bloodless coup in June 1965. He abolished the constitution and the parliament, and he himself was the leader of the 27-member Revolutionary Council, the new institution that governed the state. The members of the co ...

Pine Processionary
The pine processionary (''Thaumetopoea pityocampa'') is a moth of the subfamily Thaumetopoeinae in the family Notodontidae, known for the irritating hairs of its caterpillars, their processions, and the economic damage they cause in coniferous forests. The species was first described scientifically by Michael Denis and Ignaz Schiffermüller in 1775, though it was known to the ancients, with remedies described by Theophrastus, Dioscorides and Pliny the Elder. Its processionary behaviour was described in 1916 by the French entomologist Jean-Henri Fabre. It is one of the most destructive species to pines and cedars in Central Asia, North Africa and southern Europe. The species is notable for the behaviour of its caterpillars, which overwinter in tent-like nests high in pine trees, and which proceed through the woods in nose-to-tail columns, protected from predators by their severely irritating hairs. The species is one of the few insects where the larva develops in wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Government Of Algeria
Politics of Algeria takes place in a framework of a constitutional semi-presidential republic, whereby the President of Algeria is head of state while the Prime Minister of Algeria is the head of government. Executive power is exercised by the government. Legislative power is vested in both the government and the two chambers of parliament, the People's National Assembly and the Council of the Nation. A legacy of Algeria's bloody War of Independence from France (where an estimated 1.5 million Algerians were killed) is a powerful military and security apparatus that put a high value on secrecy. Since 1988, parties other than the ruling FLN have been allowed and multiparty elections have been held, but freedom of political speech, protest and assembly is circumscribed, and the 2014 presidential election was boycotted by major opposition parties. Algeria has been called a "controlled democracy", or a state where the military and "a select group" of unelected civilians—reportedl ...

Great Green Wall (Africa)
The Great Green Wall or Great Green Wall of the Sahara and the Sahel (french: Grande Muraille Verte pour le Sahara et le Sahel; ) is a project led by the African Union, initially conceived as a way to combat desertification in the Sahel region and hold back expansion of the Sahara, by planting a wall of trees stretching across the entire Sahel. The modern green wall has since evolved into a program promoting water harvesting techniques, greenery protection and improving indigenous land use techniques, aimed at creating a mosaic of green and productive landscapes across North Africa. The project is a response to the combined effect of natural resources degradation and drought in rural areas. It seeks to help communities mitigate and adapt to climate change as well as improve food security. The population of the Sahel is expected to double by 2039, emphasizing the importance of maintaining food production and environmental protection in the area. History In the 1950s the Brit ...

Great Green Wall (China)
The Great Green Wall, officially known as the Three-North Shelter Forest Program (), also known as the Three-North Shelterbelt Program, is a series of human-planted windbreaking forest strips (shelterbelts) in China, designed to hold back the expansion of the Gobi Desert, and provide timber to the local population. The program started in 1978, and is planned to be completed around 2050, at which point it will be long. The project's name indicates that it is to be carried out in all three of the northern regions: the North, the Northeast and the Northwest. This project has historical precedences dating back to before the Common Era. However, in premodern periods, government sponsored afforestation projects along the historical frontier regions were mostly for military fortification. Effects of the Gobi Desert China has seen of grassland overtaken every year by the Gobi Desert. Each year, dust storms blow off as much as of topsoil, and the storms are increasing in severity ea ...
