Where
is Savanna found?
Savanna
grasslands are found between tropical rainforests and desert.
This includes areas such as Central Africa (Kenya), America
and The North and East of South America (Brazil).
What
is Savanna?
Savanna
is similar to grassland but with scattered trees. These
areas have seasons: cool and dry, hot and dry followed by
warm and wet. All savanna areas have a wet and dry season.
How
did the Savanna get like this?
Nearer
the equator the heavy rainfall during the wet season, and
the fairly high total amount of rainfall during the dry
season encourages vegetation to grow. This vegetation includes
thick lush grass and heavily wooded areas. Away from the
equator, vegetation in the form of trees and poor quality
grasses are only found near rivers and water holes.
What
is the impact of humans on Savanna?
Indigenous
People (native people) - Savanna areas are popular with
nomads (people who move from place to place) e.g. Masai
tribe of Kenya. This method of farming can be beneficial
to the environment. Grazing animals are not kept in just
one area. They are moved from place to place, allowing vegetation
to recover. However, in times of serious drought animals
can remove the scarce vegetation cover. This leaves the
soil prone to erosion. Desertification (land turning to
desert) occurs in extreme cases.
Tourism
- The rich variety of wildlife in savanna areas attracts
many tourists on safari. Transport used by the tourists
often damages vegetation and scares the wildlife.
What
is the future for the Savanna? - Sustainable Development
If
development in areas of savanna is to be sustainable (e.g.
although the resources are used to aid development, it/they
will still exist for future generations to use) a number
of measures must be taken. These include:
Tourist
Guides - only using the well defined tracks when taking
tourists on safari. This will reduce soil erosion and aviod
scaring animals.
