| description | Much is discussed about the climatic changes associated with regional or global atmospheric phenomena. Empiric evidence, however, does not necessarily support such claims even though it is necessary to visualize the strength of their effects and important for the design of management and conservation agendas of those biosystems supporting the modern lifestyle. In this work, a time series analysis was carried out with monthly precipitation data from the Monte Alto Protected Zone in Hojancha, Costa Rica, for the period between May 2013 and November 2022. A disruption in the temporal pattern was detected in the rainy season of 2017 that took about two years to return to the original state. Such disruption was clearly linked with a cold period of the ENSO phenomenon, colloquially known as “La Niña”, and was followed by a second disruption with an effect lasting until this moment. The data presented herein evidence that ENSO has a direct effect on the precipitation pattern in the Monte Alto Reserve, whose original conservation purpose was to provide drinking water to local populations. The oscillations in the hydrological cycle, apparently more frequent in the last years based on the local context of this analysis, influence the quality of life of the affected populations and deserve monitoring for a proper documentation and quantification intended to increase human resilience by means of adaptation. |

Mucho se habla de los cambios climáticos producto de fenómenos atmosféricos de orden regional y global; sin embargo, no siempre se cuenta con evidencia relacionada con ellos. Esta comprobación científica es necesaria para visualizar la dimensión de su efecto y para sentar las bases de manejo y conservación de los servicios ecosistémicos que sustentan el estilo de vida moderno. En este trabajo, se ha hecho un análisis de series de tiempo del registro mensual de precipitación de la Zona Protectora Monte Alto en Hojancha, Costa Rica, para el periodo entre mayo 2013 y noviembre 2022. Se ha descubierto que una disrupción del patrón temporal de precipitación durante la temporada lluviosa del año 2017 tomó alrededor de dos años para regresar al estado original. Tal disrupción estuvo directamente vinculada con un periodo frío del fenómeno ENSO, conocido coloquialmente como “La Niña” y fue seguida por otra disrupción similar cuyo efecto continúa hasta este momento. Los datos acá presentados evidencian que el fenómeno ENSO tiene un efecto directo sobre la precipitación de la Zona Protectora Monte Alto, cuya función original en el contexto local es la de proveer agua potable a las comunidades aledañas. Las oscilaciones en el ciclo hidrológico, aparentemente más frecuentes en los últimos años en el contexto local de este análisis, tienen un efecto real sobre la calidad de vida de las poblaciones afectadas y merecen seguir siendo documentadas y cuantificadas para incrementar la resiliencia por adaptación de las sociedades afectadas.
