NAMIBIA: On the line in Namibia. We didn't follow Capricorn religiously - to do so would have required an increase in the license fee - but zig-zagged around the world tracing the southern border of the tropics.

NAMIBIA: Simon with Anyway the Jack Russell, a beautiful cheetah called Anya, and Olivier Houalet, better known as Catman, who is trying to protect the big cats at his sanctuary near the Namibian capital Windhoek.

NAMIBIA: Breakfast by the side of the road as we head east towards the border with Botswana.

NAMIBIA: We stopped for a call of nature by the road taking us east. In the tree is the communal nest of the black-chinned Social Weaver bird. Moments later a truck shot past, covering us in dust.

NAMIBIA: A hair salon in the isolated settlement of Aminius in eastern Namibia. The Herero people were forced out here by the Germans at the end of a genocidal campaign and left to suffer in the dry heat.

NAMIBIA: Batseba Ndukireepo, the daughter of the Ondagare, or keeper of the holy flame, at Otjongombe, a tiny Herero settlement close to the Botswanan border. Batseba wears the traditional Herero dress, introduced by German missionaries, comprising around 12 metres of material and 6-8 petticoats.

NAMIBIA: In an open-air kitchen at remote settlement in eastern Namibia, I warm my hands by the wood fire while Terence cooks us a buttery breakfast gruel in an iron pot.

NAMIBIA: Travelling light in eastern Namibia, Brian checks our packing list as we prepare to load one or two bags. We planned to drive into Botswana from Namibia, but the Botswanan government insisted we fly to the capital Gaborone in the east of the country to sign immigration forms.

BOTSWANA: A child plays on the bumper of our Land Rover in the tiny settlement of New Xade, to where the people of the Kalahari desert, the San bushmen, have been resettled - many against their wishes - by the Botswanan government.

BOTSWANA: Night-time around a fire in the Kalahari desert. A time for food, beer and tall-tales. Our lion-proof tents are in the background.

BOTSWANA: Mosedane Belesa (right) has returned to the middle of the Kalahari from a Botswanan government resettlement camp outside the desert. "This is home," he said.

BOTSWANA: Children of the Kalahari playing around the tiny village of Metsiamanong in English. Homes in the village consist of at least one round rondavel inside a fence made of vertical thorny branches laced tightly together.

BOTSWANA: in the Central Kalahari with 'Uncle Mongwegi', outside his home.

BOTSWANA: Making slow progress through the Kalahari Desert in a couple of old Land Rovers. The Kalahari is more like an overgrown orchard than a traditional desert, but the old tracks are tough, even for Landies.

BOTSWANA: Brian lets down the tyres on our Land Rovers to help them drive across the sand of the Kalahari Desert while Jumanda Gakelebone from the First People of the Kalahari organisation looks on.

BOTSWANA: With Tsemaletsile Maswabi, a traditional healer in the village of Otse near Capricorn. In sub-Saharan Africa there is roughly one traditional healer per 500 people, compared to one doctor per 40,000 people. The Botswanan government uses healers to spread a safe sex message, distribute condoms, and encourage people to have HIV tests.
