Given the projected impacts of climate change on human well-being, it is important to understand the pathways connecting climate conditions and human outcomes. Despite a growing body of research on the topic, the human impacts of climate change remain poorly quantified. In that respect, household agricultural output is often implicitly considered as a linkage between climatic conditions and household food security, but few studies have tested this relationship explicitly.

In this study we attempt to test an agricultural pathway hypothesis between observed weather conditions and two types of outcomes: household food security outcomes and child nutritional outcomes. The study is set in Uganda and uses nationally representative longitudinal household survey data from 2013 through 2019. We first investigate how time-varying rainfall and temperature regimes in the preceding agricultural season are associated with household food security outcomes and child nutritional outcomes. In a second stage, we investigate how the observed associations change after incorporating measures of household agriculture. The results of this study will be informative for quantifying the indirect impacts of climate change and improve our understanding of the complex relationship between weather, agriculture, and food security in low-income households.
