In Kenya a bruising and recurring drought is driving huge numbers of subsistence farmers away from rural areas, where they are increasingly reliant on hand-outs, into congested slums. Many farmers in the region have already abandoned the land, at least temporarily, in favour of producing and selling charcoal or breaking stones in a nearby quarry for a local construction company. The work is both back-breaking and ill-paid. A 20-litre jerry can of ballast is paid five shillings. - AFP Photos/Tony Karumba[imagebrowser id=10012]
