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 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. Zambia if one of the countries where the FSP project has such activities. This data asset includes two Datasets of survey data from stakeholder surveys conducted in 2019. One dataset is about stakeholder perceptions of the quality of agriculture and food security policy processes in Zambia, and the quality of the institutional architecture for agriculture and food security policy processes.
