Fall 2025 Harry ’51 and Joshua ’49 Tsujimoto Perspectives in Global Development Seminar Series

About the speaker

Arie Sanders holds a PhD in Rural Sociology from Penn State University and a Master’s and BSc in Development Economics from Wageningen University & Research. He is the Associate Dean of the Graduate Program and Associate Professor in Agribusiness at Zamorano University, Honduras. With more than 30 years of experience in international development, Dr. Sanders has led initiatives on small-scale agriculture, value chain development, and gender inclusion across Central America. He has collaborated with the Feed the Future Innovation Lab on research in horticulture, gender, and sustainable production systems, and is currently working with the Smithsonian Institution on the governance of coastal resources in Central America.

Abstract

My talk examines pesticide use among smallholder potato farmers in Intibucá, Honduras, and how these practices are shaped by social as well as agronomic factors. Potatoes are a key livelihood crop in the highlands, but pest pressures, monocropping, and volatile markets have pushed farmers toward increasingly intensive pesticide regimes. While these applications help protect yields, they also bring significant costs—rising resistance, contamination of soil and water, and health risks for farming families.


I argue that pesticide use cannot be understood only as a technical matter. It is also a social act, tied to local norms of what it means to be a “good farmer.” In Intibucá, tidy, disease-free fields are visible symbols of skill and responsibility, reinforcing reputation and access to resources. This symbolic capital makes heavy spraying appear not just logical, but necessary. Drawing on Bourdieu’s concepts of habitus, field, and capital, I show how recognition, peer validation, and memory of past crop failures sustain these routines.


The talk also explores the potential of alternatives such as the Decision-Support-System Disk, a tool that can reduce fungicide use by up to 30% without yield loss. Yet, adoption is constrained because experimenting carries social risks: visible mistakes can damage reputation. Generational and gendered dynamics matter too—young farmers are more open to change, and women often manage the hidden health risks of pesticide use, though their knowledge is undervalued.


I conclude that promoting sustainable pest management requires more than introducing new technologies. Progress depends on engaging with the social dynamics of rural life—farmer-led trials, peer-to-peer learning, and incentives that reward careful rather than intensive management. Redefining what it means to be a good farmer is central to building healthier, more resilient production systems in Honduras.
