1. Introduction
Lake Tanganyika has the
largest volume of the three
African Great Rift Valley lakes.
It also is the second deepest,
and the second largest lake
in the world by volume,
containing almost 19,000 km3
of water--only Lake Baikal is
larger. The lake contains almost
as much freshwater as the fi ve
North American Great Lakes
combined. It contains a volume
of water seven times more than
that of Lake Victoria, which is
the largest lake by area in Africa.
It has a length of more than 670
km and an average width of 48
km. The length of the shoreline
is about 1,900 km, of which
43% is rocky, 21% is mixed rock
and sand, 31% is sand, and 10%
is marshes. Figure 1 depicts the
lake and its basin.
2. Background
The main economic activity
of the 10 million people
living in the lake's drainage
basin is agriculture. The
main agricultural products
include maize, tobacco, rice,
sugarcane, coffee, beans,
groundnuts, cassava, cattle
and goats. The socio-economic
statistics for the riparian
nations of Lake Tanganyika
are given in Table 1. Tanzania,
