AP Explains: How Kenya’s drought has turned into violence.
It was not the first time the luxury tourism lodges at her Laikipia Nature Conservancy had been targeted.
At least 30 people have been killed in recent conflicts over grazing land.
Here’s a look at why the tensions emerged and the political angle some say exists.
According to Kenya’s government, hundreds if not thousands of herders have sought pasture in Laikipia, the region where Gallmann was shot, for their dying cattle.
The Laikipia Farmers Association says more than 30 people have died since the land invasions started late last year.
Land has been one of the major causes of conflict in Kenya, where many ranches, some of which double as wildlife conservancies, were acquired during the period of British colonial rule.
There has never been any sustained government effort to address land injustices that have claimed since colonial times.
The Laikipia Farmers Association says it previously had arrangements with herders to allow them to feed their animals on the ranches when there is little or no grazing elsewhere.
But the association says the current invasions have been incited by politicians campaigning for the August elections.
