This document discusses tea production in Kenya through two main procurement models - plantations and the Kenya Tea Development Agency (KTDA). The KTDA model involves over 560,000 smallholder farmers who supply green tea leaves to buying centers, which are then processed at factories and sold primarily through Mombasa auctions. Key factors in the success of the KTDA model include high returns provided to farmers, timely payments, transparency, and services around inputs and training. Unilever procures tea through both the auction and direct sales, and supports farmer training and certification through KTDA to improve yields, quality, and sustainability of tea production in Kenya.
