Performance différenciée du coton Bt en début de diffusion : cas du Burkina Faso

Abstract: L’avantage économique des cultures transgéniques pour les producteurs des pays en développement reste un sujet de préoccupation et de controverse. Seules quelques études ont pris en compte les différences entre producteurs pour comprendre les performances variables des cultures transgéniques, notamment dans le cas du coton Bt incorporant des gènes de la bactérie Bacillus thuringiensis pour la résistance à certains ravageurs du coton. Notre étude d’évaluation concerne le Burkina Faso où la diffusion à grande éc… Show more

“…Activists were regularly dismissed by mainstream cotton sector employees as uninformed and anti-science. Yet many activist concerns about Bt cotton have been substantiated by recent social science (Dowd-Uribe, 2014a;Renaudin et al, 2012;Vognan & Fok, 2019) and deserve closer attention. On the other side, GM crop promoters' narrow evaluation methodologies and dismissal of 'traditional-minded' peasants limited their ability to recognize problems.…”

“…Many farmers struggle to follow timing recommendations because they are juggling multiple crops, multiple fields, unpredictable weather, lack of access to farm equipment such as oxen, and severe labour shortages (Luna, 2020). Poorer farmers in particular struggle to mobilize the resources needed to get good yields with Bt cotton, particularly fertilizer application (Gray & Dowd-Uribe, 2013;Vognan & Fok, 2019). Narratives about average yield gains in ideal conditions thus do not reflect the wide variety of conditions in farmers' fields.…”

“…There is special emphasis on improving our understanding of the life cycles of pests and their natural enemies (Brévault et al, 2019) with the aim of developing approaches that stimulate ecological processes of natural pest control (Brévault et al, 2019) and reduce pesticide use, e.g. by growing Bt cotton (Vognan and Fok, 2019) or topping (Diarra et al, 2020). It is important to inform, raise awareness and train the actors in the sector to ensure that they know about the environmental and health risks involved in pesticide use (Djagani and Fok, 2019), as well as the good practices to adopt when using pesticides (choice of pesticides, field application, etc.)…”

“…Une bonne partie des articles traitent des pratiques de gestion des ravageurs dans les systèmes de production, afin de les rendre plus économes en pesticides, plus respectueux de la santé humaine et de l'environnement, et plus résilients. Un accent particulier est mis sur l'approfondissement des connaissances du système de vie des ravageurs et de leurs ennemis naturels (Brévault et al, 2019), pour travailler sur des approches visant à stimuler les processus écologiques de régulation naturelle des ravageurs (Brévault et al, 2019) et à réduire l'utilisation des pesticides : coton Bt (Vognan et Fok, 2019) ou écimage du cotonnier (Diarra et al, 2020). Ensuite, il est important d'informer, de sensibiliser et de former les acteurs de la filière sur les dangers liés à l'utilisation des pesticides sur la santé et sur l'environnement (Djagani et Fok, 2019) et sur les bonnes pratiques à adopter pour la lutte chimique, depuis le choix des pesticides jusqu'à leur application au champ (Le Bars et al, 2020).…”
