The formation of vegetation patterns is a combination of many phenomena and usually includes some form of a directional aspect. It is a general term, without specific reference to particular taxa, life forms, structure, spatial extent, or any other specific botanical or geographic characteristics. The vegetation types usually considered as ‘typically Mediterranean’ are the evergreen and sclerophyllous shrublands or heathlands, named maquis and garrigue in the Mediterranean Basin, chaparral in California, matorral in Chile, fynbos in SW Africa, kwongan and mallee in SW Australia. Rain Forest: About one-half of the world’s forest area is located collectively in tropical Africa, tropical America and tropical Asia. Savanna zones have a seasonal humid climate with a marked change from dry to rainy periods, which causes the seasonal rhythm of all natural processes. The average temperature of the coldest months in the temperate zone is lower than that of the tropical zones, while the average temperature of the warmest months in the temperate zone is higher than that of the polar zone. 1.

The northern margin is an isolated forest outlier along the Jubba Valley in central coastal Somalia (Madgwick 1988). Climate change in africa impacts on agriculture. A biome can be defined as a region sharing similar habitats or vegetation types at a global scale. Its complex terrain, unequaled in the rest of Africa, results in a huge diversity of climatic conditions that steer a wide range of vegetation landscapes, biodiversity … The migration of the inter-tropical convergence zone (ITCZ) in Africa affects seasonal precipitation patterns across that continent. Vegetation varies from sand dunes and rocky wastes to dense green rain forests. The zone Eastern Africa, classically presented as a major dry climate anomaly region in the otherwise wet equatorial belt, is a transition zone between the monsoon domains of West Africa and the Indian Ocean.

This symmetry is, however, imperfect because of a third … These regions usually experience 2000 mm of rainfall or more in a year. Using the West Africa rainfall isohyets as a general reference, as well as the extent and pattern of the dense forest depicted on the 1975 map, the probable limits of the Upper Guinean dense forest (prior to 1900) have been delineated (see map below). Forest West Africa’s climate is controlled by the interaction of two air masses, the influence of which varies throughout the year with the north-south movement of the Intertropical Convergence Zone (ITCZ).

ADVERTISEMENTS: In this article we will discuss about:- 1. The main physical features include the Sahara Desert and the Niger River. He described vegetation patterns at a scale that is still smaller than the biome. Due to higher temperatures in the valleys, there is a high rate of transpiration (plants losing water) and evaporation, which requires irrigated agriculture. There are 5 main climate zones, each with a number of sub-climate zones, as shown in the map and described in the table below. Vegetation is a general term for the plant life of a region; it refers to the ground cover provided by plants, and is, by far, the most abundant biotic element of the biosphere.
