TROPICAL CLIMATES
   RAIN FOREST

         Wettest climate in region
         Near the equator
         Warm temps.
         60 inches of annual rainfall
         Canopy trees grow up to 150 ft
HUMAN - ENVIRONMENT
          INTERACTION
Rain leaches soil
Can still grow cash
crops 
 banana, pineapples,
 cocoa, tea, coffee, palms
 for oil, rubber and cotton

Deforestation

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
                   moisture

                   Grass as tall as 15 ft

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
DESERT

    South - Namib and
    Kalahari
    North - Sahara
    Kenya and Somalia
    are mostly deserts in
    the east

  • #5 \n
  • #6 \n
  • #7 Congo Basin contains the second largest expanse of tropical rainforest in the world. \n
  • #8 Deforestation: extensive woodlands remain in africa but many have been replaced by grasslands, and farms.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

  • #10 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
  • #11 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
  • #12 Sahara, Namib, Kalahari\nHorn of Africa - Northeastern corner that includes Somalia, Ethiopia, Djibouti, and Eritrea. \n
