In Tanzania, BNFB is focusing on three crops: orange-fleshed sweetpotato (OFSP), pro-vitamin A (PVA) maize and high iron and zinc beans. To better understand the gaps, define the priorities and develop the necessary interventions to address the issues affecting the scaling up of biofortification in Tanzania, the project conducted a situation analysis between October 2016 and May 2017. The primary aim was to gather analytical data and information that establish the baseline status of biofortified crops and nutrition in Tanzania. That information was needed to develop the national advocacy, seed systems and capacity building strategies and plans for 2016–2018 for the project. The study also aimed to identify the key actors in biofortification, to map out the gaps in ongoing complementary initiatives to which BNFB could contribute in closing, and to recommend the necessary action on issues affecting the scaling up of biofortification in the country.
