  • Congo Basin contains the second largest expanse of tropical rainforest in the world. \n
  • Deforestation: extensive woodlands remain in africa but many have been replaced by grasslands, and farms. The result is shortages in biofuels (wood and charcoal used for household energy needs, especially cooking)\nKenya’s green belt movement, plant millions of trees.\n\nAgricultural Substance: Stable crops of millet, sorgum, corn. Swidden Agriculture practices in Areas with poorer tropical soil.\n\nShifting cultivation: burning natural vegetation to release fertility, then plant indigenous crops; allow fallow periods. Often fine tuned to local conditions, but unable to support high population densities.\n\nPlantation agriculture: export crops are ciritical to the economies of many african states: Coffee, Peanuts, Cotton, Cocoa, Rubber.\n

  • Savannas: wet and dry savannas surround central African rainforest belt. \n\nThe Serengeti hosts the largest mammal migration in the world, which is one of the ten natural travel wonders of the world.[1]\nThe region contains one national park: Serengeti National Park and several game reserves. Serengeti is derived from the Maasai language, Maa; specifically, "Serengit" meaning "Endless Plains".[2][3]\nApproximately 70 larger mammal and some 500 avifauna species are found there. This high diversity in terms of species is a function of diverse habitats ranging from riverine forests, swamps, kopjes, grasslands and woodlands.[4] Blue Wildebeests, gazelles, zebras and buffalos are some of the commonly found large mammals in the region.\nCurrently there is controversy surrounding a proposed road that is to be built through the Serengeti in Tanzania.\n\n
  • Sahel- zone of ecological transition between the Sahara to the north and wetter savannas and forest to the south\nDesertification: the expansion of desert-like conditions as a result of human-induced degradation.\n\nTranshumance is the movement of animals between we-season and dry season pasture \n
  • Sahara, Namib, Kalahari\nHorn of Africa - Northeastern corner that includes Somalia, Ethiopia, Djibouti, and Eritrea. \n

    12. 12. TROPICAL SAVANNAS Grasslands w/scattered trees Cover almost 1/2 of Africa Seasonal rainfall - wetter near equator Dry air from Sahara carried by harmattan drys moistureSerengeti Plains Grass as tall as 15 ft

    14. 14. SAHEL Means “shore” - represents “coast” of the Sahara Dry land between Senegal and Sudan Expanding due to decline in rain, climate change, overgrazing and population growth Transhumance
