"Since independence, city planning in Kenya has not been carried out effectively," asserts Professor Washington Olima of the University of Nairobi. In the absence of a clear landuse policy, urban agriculture is currently thriving in Kenya. But, according to Olima, the confused policy situation and lack of overall coordination leads to conflicting implementation of different land use activities. Little consideration has been given to the areas allocated to agriculture, and the outcome has been to put people's health at risk.
