Participatory evaluation
of improved bean varieties
Erratic patterns in rainfall and hailstorms might
increase plant health risks in traditional varieties due
to their lack of genetic resistance to certain
pathogens that are endemic in those areas.
Climate challenge
Evaluation of improved climbing beans varieties on pathogen resistance and water stress, as well as biofortified
bush beans varieties. The evaluation is done in the farm where the farmer implements both guided and traditional
practices. The farmer registers plant development, crop performance and pests and diseases appearence in
addition to climate monitoring, in order to provide feedback to the researcher.
The practice emphasizes adaptation, food security and productivity, although the minimal management of
agrochemical inputs also contributes to the mitigation pillar.
