The Overview · Kenya
Geography and the Land
Kenya covers about 580,000 square kilometres and straddles the equator. Within that space are some of Africa's most dramatic landscapes: a coastline on the Indian Ocean, dry plains in the east and north, cool green highlands in the centre, the Great Rift Valley, and the Lake Victoria basin in the west.
Height shapes everything. Mount Kenya, at 5,199 metres, is Africa's second-highest mountain. The highlands around it, and around Mount Elgon and the Mau escarpment, are cool, fertile and well watered. These forests are called Kenya's 'water towers' because they feed most of its rivers. But more than three quarters of Kenya is arid or semi-arid, where rain is scarce and unpredictable.
The Great Rift Valley was formed by the slow pulling apart of the Earth's crust. Its lakes, volcanoes and hot springs also make it a source of geothermal energy, which now provides a large share of Kenya's electricity.
Kenya is one of the most important places on Earth for studying human origins. Stone tools about 3.3 million years old have been found at Lomekwi, near Lake Turkana, and in 1984 Kamoya Kimeu discovered the fossil skeleton known as Turkana Boy at Nariokotome, a remarkably complete skeleton about 1.5 million years old.
Geography shaped Kenya's history. The coast's monsoon winds connected it to Indian Ocean trade. The dry plains suited pastoralists such as the Maasai and Turkana. The fertile highlands attracted British settlers, who took them as the 'White Highlands'. The railway from Mombasa needed a depot halfway, and in 1899 a camp at Enkare Nairobi grew into the capital.
Today the land is under pressure. Forests have been cleared, droughts are becoming more frequent, and the 2020–23 drought was one of the worst in decades. Wangari Maathai's Green Belt Movement showed how planting trees could protect both the land and the people who depend on it.

The Debate
Is geography destiny?
The highlands' climate attracted settlers; the drylands' scarcity shaped pastoral life. But people made choices: Britain chose to seize land, and independent governments chose how to share it. Geography sets limits and offers opportunities; it does not decide outcomes.
Discussion prompt
The highlands' cool climate and rich soil made them the land settlers wanted most. How much do you think geography explains the history that followed?
