Study design

The survey was conducted in the Tana Delta area itself; referred to as Bilisa, and in Assa location, a more arid region to the west, in order to investigate differences in management practices between the two regions and their impact on milk offtake.

A series of questions were asked of the household head (Irungu, 2000); those related to family size CS1Quest1 and milk sales and milk consumption in the households CS1Quest2 are included here. As will be seen during the course of this case study the form that the questioning took proved not to be ideal. For a preliminary study such as this the range of questions was too wide. This meant that the length of the interview was a little long with the result that, as will be seen later, information was incomplete.
