This document discusses incorporating household dietary and nutritional needs in quantitative farming systems analysis. It presents a conceptual framework that describes the relevant concepts and relationships. This includes the interactions between household nutrition, human health and capacities, farm productivity, and off-farm food acquisition. The framework identifies three options for incorporating nutrition: 1) using dietary diversity as a proxy, 2) assessing nutrient balance, and 3) analyzing food patterns. It provides an overview of the focus, information requirements, uses, and whether the options take into account nutritional and dietary needs of households. The goal is to help improve smallholder farming systems and eradicate hunger by considering the impact on household nutrition when intensifying agriculture.
