Levelling the field: a review of the ICT revolution and agricultural extension in the Global South
(2025) Khan, Rashid Parvez; Gupta, Saurabh; Daum, Thomas; Birner, Regina; Ringler, Claudia
Information and communications technology has evolved significantly over the last seven decades, beginning with radio and video vans and culminating in the rise of smartphones and mobile internet in remote areas of the Global South. While ICT is an integral part of agricultural extension, little is known about how these changes have influenced agricultural extension practices. After a systematic review of 131 papers, we find that changes in ICT have shaped agricultural extension, enabling a shift from linear dissemination and “one‐way communication” to co‐innovation and farmer‐to‐farmer learning. The results indicate the potential for smartphones and mobile internet to democratize agricultural extension.
Optimistic narrative future visions: a communication tool for promoting sustainable (plastic) behavior
(2023) Neef, Nicolas E.; Fußwinkel, Selina; Roos, Claudine; Frank, Lilli; Shihepo, Kapandu; Richter, Isabell
Plastic pollution is a pressing global issue, necessitating a focus on consumer behavior to curb this problem at its source. To effectively promote sustainable practices, communication strategies that employ future visions have gained attention. This study examines the effects of a narrative video intervention depicting an optimistic future vision concerning single-use plastic bag consumption in South Africa, compared to a representation of the prevailing status quo. Using a preregistered within-subject design, we assess the psychological and emotional responses to two scenarios of which one is illustrating adaptive behaviors toward reduced plastic bag usage, and the other showcasing current consumption patterns. Parametric analyses revealed a shift in emotional states, characterized by a greater experience of positive emotions and a reduced experience of negative emotions following the exposure to the optimistic future scenario video, as compared to the status quo video. Moreover, engagement with the optimistic future scenario was associated with higher levels of perceived behavioral control and behavioral intentions. No significant changes were found regarding sense of responsibility. These findings point to the potential of optimistic future visions to influence individuals at psychological and emotional levels. This renders optimistic future vision communication as an effective tool for sustainable behavior change, particularly in relation to the sustainable use of plastic shopping bags.
