Exploring varietal uptake through a gender lens: Insights from a multi-country, multi-crop qualitative study por Cavicchioli, Martina

“…Our results suggest behavioral attitudes such as risk aversion based on previous experiences with improved variety and knowledge gained through community seed- delivery channels or peer-to-peer exchanges are critical in driving decisions about varietal adoption for both women and men. However, if unpacked through a gendered, intersectional lens, behavioral attitudes appear as a composition of multiple barriers and drivers that are differently experienced and, most importantly, prioritized by women and men. …”
