Algiers vs Savannah

Informations

Algiers ( al-JEERZ; Arabic: الجزائر‎; Berber: Dzayer; French: Alger) is the capital and largest city of Algeria. The city's population at the 2008 Census was 2,988,145 and in 2011 was estimated to be around 3,500,000. An estimate puts the population of the larger metropolitan city to be around 5,000,000. Algiers is located on the Mediterranean Sea and at the north-central portion of Algeria.

Algiers is located on the west side of a bay of the Mediterranean Sea. The modern area of the town is built on the level ground by the seashore; the older part, the ancient city of the deys, climbs the steep hill behind the modern city and is crowned by the casbah or citadel, 122 metres (400 ft) above the sea. The casbah and the two quays form a triangle.

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.
