The Rapid Expansion of Herbicide Use in Smallholder Agriculture in Ethiopia: Patterns, Drivers, and Implications

Abstract

Adoption of herbicides by Ethiopian smallholders has grown rapidly, with application on cereals doubling to more than a quarter of the area under cereals between 2004 and 2014. Relying on unique data from a large-scale survey of producers of teff, the most widely grown cereal in Ethiopia, we find considerable positive labor productivity effects of herbicide use of between 9 and 18 per cent. We show that the adoption of herbicides is strongly related to proximity to urban centers, access to all-weather roads, and levels of local rural wages. All these factors have changed substantially over the last decade in Ethiopia, explaining the rapid take-off in herbicide adoption. The sizable increase in herbicide use in Ethiopia has important implications for rural labor markets, potential environmental and health considerations, and capacity development for the design and effective implementation of regulatory policies on herbicides.

Cet article étudie l’utilisation des herbicides en Éthiopie. Il révèle une augmentation rapide des importations d’herbicides dans le secteur privé en Ethiopie (une valeur quadruplée au cours de la dernière décennie). L’adoption des herbicides par les petits exploitants a augmenté rapidement, en particulier l’application dans le domaine des céréales qui a plus que doublé au cours des dix dernières années, attenant plus d’un quart de ce secteur en 2014. Nous constatons d’importants effets positifs sur la productivité du travail pour ceux qui adoptent de 9 à 18 pourcent. Nous montrons que l’adoption des herbicides est fortement liée à la proximité d’une ville, aux salaires ruraux, et à l’accès aux marchés. Tous ces facteurs ont considérablement changés au cours de la dernière décennie en Éthiopie, ce qui semble expliquer la popularité de l’adoption des herbicides. Ce changement a des répercussions importantes sur les marchés du travail ruraux, sur les considérations potentielles en matière d’environnement et de la santé, et sur les besoins en matière de renforcement des capacités pour la conception et la mise en œuvre de politiques réglementaires.
