Savannah vs Ghadames

Informations

A savanna or savannah is a mixed woodland-grassland ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests. The South American savanna types cerrado sensu stricto and cerrado dense typically have densities of trees similar to or higher than that found in South American tropical forests, with savanna ranging from 800–3300 trees per hectare (trees/ha) and adjacent forests with 800–2000 trees/ha.

Similarly Guinean savanna has 129 trees/ha, compared to 103 for riparian forest, while Eastern Australian sclerophyll forests have average tree densities of approximately 100 per hectare, comparable to savannas in the same region.Savannas are also characterised by seasonal water availability, with the majority of rainfall confined to one season; they are associated with several types of biomes, and are frequently in a transitional zone between forest and desert or grassland. Savanna covers approximately 20% of the Earth's land area.

Ghadames or Ghadamis (Berber: ʕademis; Arabic: غدامس‎, Libyan vernacular: ɣdāməs, Latin: Cidamus, Cydamus, Italian: Gadames) is an oasis Berber town in the Nalut District of the Tripolitania region in northwestern Libya. The indigenous language of Ghadames is Ghadamès, a Berber language. Ghadamès, known as 'the pearl of the desert', stands in an oasis. It is one of the oldest pre-Saharan cities and an outstanding example of a traditional settlement.

Its domestic architecture is characterized by a vertical division of functions: the ground floor used to store supplies; then another floor for the family, overhanging covered alleys that create what is almost an underground network of passageways; and, at the top, open-air terraces reserved for the women.
