Maasai herdsmen in Kenya have turned to an age-old contraceptive device, the "olor", to protect their precious goat herds from an ongoing drought.
The olor is made from cowhide or a square piece of plastic, and is tied around the belly of the male goat.
It prevents the bucks from mating with the female goats.
The herdsmen are using the device to limit the goat population and ensure there are not too many animals grazing on sparse vegetation.
"We don't want them to breed in this drought," says Mr Ole Ngoshoi Kipameto, a goat owner in Kajiado district.
The area, which is 80km (50 miles) from the capital, Nairobi, has received insufficient rainfall, making the landscape barren and forcing residents to move from place to place in search of pasture and water.
In the Maasai community, livestock are often people's only assets and sole means of survival.
"We tie this hide under the belly of the buck for three months. After that we remove it and then they can breed by November when the short rains come," Mr Kipameto says.
