Evaluación económica de las pérdida por granizo en los oasis de la la provincia de Mendoza e identificación de eventos extremos

Hailstorms are one of the main threats to the sustainability of agricultural systems in Mendoza, which generate a disturbance factor for production forecasts; although they constitute events of random nature, the spatial distribution and the levels of intensity (and damage) acquire differential aspects depending on the allocation. The goal of the present work was to evaluate the economic losses in crops and determine the frequency and magnitude of extreme phenomena, resorting as primary source of data the records of complaints of these disasters. The economic losses attributable to the impact of "mangas de piedra" were calculated from this information of observational nature, and the phenomena in each campaign were then classified as extreme and very extreme, due to their relative level of losses. This work allowed qualifying the different departments according to their risk and the occurrence of extreme events, as well as the behavior of each campaign from 1993 to 2019, which will contribute to the generation of trend models of these phenomena. These models will be useful for the formulation of management strategies of climate risk and territorial planning.
