There are an estimated 100,000 Bushmen across southern Africa, mainly in Botswana, Namibia, South Africa and Zambia. Thousands of Bushmen lived in the vast expanse of the Kalahari Desert for many millennia. But today most have been moved, many argue forcibly, to government-built resettlement camps far from the reserve.
New Xade, a resettlement camp an hour's drive from the nearest town, Ghanzi, in western Botswana. It is the new home of the Basarwa - Kalahari Bushmen. They do not take much pleasure in this honour.
Sisters Boitumelo Lobelo, 25, and Goiotseone Lobelo, 21, are kneeling in front of a basin of dirty water, washing their children's clothes. They speak fondly of life in the reserve, where they would wake up every morning and join the women in the village in collecting berries, nuts and roots to eat. Their eyes fill with anger when they speak of their life here, a desolate village half a day's drive from their original home, which is now part of the Central Kalahari Game Reserve (CKGR).
“I miss my home and the way we lived. Life was easy, there were lots of fruits, animals and there were no bars and no beer. Now we are lost," says Goiotseone. She also remembers the day they were forced to leave "The police came, destroyed our homes and dumped us in the back of trucks with our belongings and brought us here. They dumped us here like we are nothing,"
These two are the new generation of Basarwa: they go to school and have learned English and the Tswana language, the most widely spoken in the country. But they say this new life has come at too high a price. "We are getting Aids and other diseases we didn't know about; young people are drinking alcohol; young girls are having babies. Everything is wrong here," Boitumelo says.
Unemployment is high and this community has no expertise to speak of, or at least none that they can use in the outside world. The village's liquor shop has no shortage of customers. It is not uncommon to see young men stumbling out of local watering holes in the mid-afternoon.
When the Bushmen were relocated, each family was given five cattle or goats to encourage them to become farmers. "If you push somebody to a certain kind of lifestyle that he doesn't know, he will be facing a lot of difficulties," says one bushman farmer, Jumanda Galekebone. "Our people don't know how to look after the cows when they get sick, they don't know about diseases of cattle like foot and mouth disease," he explains.
Modern life has not worked for them. "This life hasn't improved any of their lives. We still get a lot of people going inside the park to hunt and they get arrested. Some of us here are facing court penalties for hunting. It just proves that you can't force change on people."
For a people who have spent most of their lives roaming the land freely, hunting wild animals and gathering berries and nuts for food, this place offers them no chance to live off the land.
"We are used to feeding ourselves - now dependant on government hand-outs, we are being made lazy and stupid," says Mr Sesana. "Now we are being treated like dogs. The dog is the only thing that can't bring its own food home. It has to wait for its owner to give it some food." "The only place where you find Bushmen now in our traditional clothes surrounded by traditional huts is in the local tourism villages," says Mr Sesana. "We are worried that in the future, there will be no-one who would be able to practice the Bushman culture unless they are parading in front of tourist for companies who are using them for business," he says.
The Botswana Bushmen have been at odds with the country's government for more than 15 years, embroiled in several legal battles over their right to live inside the game park - and to continue their traditional lifestyle as hunter-gatherers. At some point they were denied access to water in the reserve. Their boreholes were capped and they were banned from drilling more. The Botswana Appeals Court, in a 2011 judgment on the matter, described the plight of the Bushmen as a "harrowing story of human suffering and despair" and ruled that they be allowed access to water. In 2006, another court ruled that the government's refusal to allow the Basarwa into the CKGR was unconstitutional. A handful have been allowed by officials to return to the park but only those whose names appeared in the court papers. Today many say court orders in their favour have been ignored by officials. They need permits to enter the reserve and are not allowed to hunt. Those found hunting face arrest.
Why were they relocated? The government says the restriction of people on the land is intended to preserve the wildlife and the ecosystems of the vast reserve, which is slightly bigger than Denmark. But human rights groups and the Bushmen believe the real reason is more sinister Mining is one of Botswana's key industries, with diamond mining the leading source of revenue. The ancestral lands of the Bushmen lie in the middle of the world's richest diamond field. They believe they were relocated to make way for a multi-million dollar mining project. A London-listed diamond producer has begun plans for production about 45km (28 miles) from the eastern border of the reserve. Construction of the first phase of the project began in 2011. It is expected to begin production in 2014, with an initial output of 70,000 tonnes of rough diamonds.
Some believe that the Bushmen's way of life does not belong in modern Botswana society. Some officials have referred to them as "remote area dwellers", a "Stone-Age" people who should be pulled into the 21st Century. President Ian Khama, has announced that hunting in controlled areas would be outlawed by January 2014. He said the Bushmen would be taught "non-consumptive" ways of using their resources.
Bushmen argue that their years of living in harmony with the environment prove that their ways are ecologically sustainable. They say instead that this move is an attempt to do away with their culture.
