Climate adaptation requires farmers to adjust their crop varieties over
time and use the right varieties to minimize climate risk.
Authors used a
scalable approach to on-farm participatory variety evaluation using
crowdsourced citizen science, assigning small experimental tasks to many
volunteering farmers. They generated a unique dataset from 12,409 trial
plots in Nicaragua, Ethiopia, and India, a participatory variety
evaluation dataset of large size and scope. This shows the potential of
crowdsourced citizen science to generate insights into variety
adaptation, recommend adapted varieties, and help smallholder farmers
respond to climate change.
