It's just before sunset, the time of day when Maasai herdsman Josphat Ole Tonkei would have been counting his herd of cows after hours in the grazing fields, a few years ago.
Today Tonkei must wait until darkness to perform the check. The routes to grazing fields and water points have been blocked and he has to take a long, alternative route to reach his "Manyatta", or homestead, where he counts his herd.
