Brewis, Workman et al. (2020) provided a basis for significant subsequent advancement in understanding the interplay between household water insecurity and food insecurity across diverse global contexts. This commentary reflects on the subsequent evolution of research and its application in the 5 years since the study's initial online publication in AJHB, highlighting dynamic mechanisms that link water insecurity and food insecurity and the implications for human health. Newer studies suggest that water insecurity may drive food insecurity more significantly than vice versa, with localized case studies revealing the diversity and complexity of multi-scalar factors that contribute to these relationships. Future research priorities include more refined water insecurity measurement tools and further testing of potential mechanisms in theorized causal pathways linking water insecurity and food insecurity to each other and health outcomes.
