One of the objectives of the Feed the Future (FTF) Innovation Lab for Food Security Policy (FSP) project is to foster credible, inclusive, transparent and sustainable policy processes at country level. As part of the monitoring and evaluation framework of FSP, the project has proposed two contextual qualitative indicators to assess and track the institutional architecture and quality of policy processes on agriculture and food security in FTF countries where the project has major country level activities. Tanzania is one of the countries where the FSP project has such activities. This dataset represents a survey conducted in 2019 to assess and monitor: 1) the quality of agriculture and food security policy processes in Tanzania, and 2) quality of the institutional architecture for agriculture and food security policy processes, as measured by stakeholder evaluation survey to capture the level of satisfaction and confidence. This is a follow up survey to a similar survey conducted in 2016 to better understand any changes over the past three years.
