This is the annual report of the Cassava Community Action Research Project (Cassava CARP) for the period October 2015 – September 2016. The Cassava CARP is aimed at enhancing sustainable production, processing and marketing of cassava and cassava products among the cassava farming communities. Its focus is on quality cassava planting material, appropriate agronomic practices and promotion of relevant technologies for improved performance of selected value chains. The primary entry point is to ensure access to virus-free and good quality cassava planting material of farmer preferred and elite varieties. Through existing multi-stakeholder innovation platforms, farmers and other actors are being engaged in each of the four pilot study districts, where cassava plays a vital role of food security and bio-resource. The focus districts include Kole and Apac (Northern Uganda), and Serere and Bukedea (Eastern Uganda); and some R4D activities at Makerere University Agricultural Research Institute at Kabanyolo (MUARIK, Wakiso district).
