Navigating the Measurement Frontier: New Insights Into Small Farm Realities

Measurement is not only a way of describing complex realities; it can also transform those realities by influencing policies. We live in an era of measurement innovation: new methods to deploy and new ways of adapting familiar, proven strategies to new contexts. This paper explores how new measurements provide fresh insights into the circumstances of small-farm households worldwide and describes challenges that these techniques have yet to overcome. Because the small farm sector plays a crucial role in global food security, global value chains, and rural livelihoods, understanding its conditions is a persistent focus of policymakers and researchers. I discuss how measures including satellite-based assessments of crop yields, tree cover, temperature, and rainfall, laboratory measures of soil and agricultural input quality, GPS-based plot area calculations, labor activity trackers, and high-frequency household surveys conducted via cellular phones are providing an improved understanding of fundamental dimensions of small farms and agrarian households. I identify important gaps in what is currently measured, discuss challenges related to implementing and interpreting new measures, and argue that new measurement strategies should be combined with continued investment for traditional “analog measures”—the household and farm surveys that remain fundamental for data collection in low- and middle-income countries (LMICs).
