Weather in the Andean high plateau is characterized by extreme climate events with serious impacts on agriculture, increasing the vulnerability of farmers. The lack of forecast weather stations in the region leads to a lack of data, weakening timely decision-making. The implementation of modern agro meteorological services would imply high costs. However, local communities in the Omasuyo province in Bolivia traditionally rely on the observation of local bioindicators, which provide a kind of local agro meteorological service that has produced reliable guidance for mitigating the impacts of extreme climate events on crops.
