This study investigates the spatial and temporal variation of the rainy season on the slopes of Lake Titicaca by analyzing rainfall series extracted from the gridded database PISCOp V2.1 and 18 meteorological stations within the study area. The onset and end of the wet season from 1981 to 2012 were evaluated using gridded data, which were then validated with recorded rainfall data and performance statistical indicators. This methodology allowed the determination of the onset and end of the rainy season for each hydrological year of the study period, and the calculation of metrics such as rainy days, wet season rainfall, and rainfall intensity. The resulting time series were subjected to trend analysis, revealing that, in general, they did not exhibit statistically significant trends. This conclusion was also supported by the trend analysis of the series derived from the gridded data. The...

The study aimed to create a geospatial model to identify agroecologically and economically viable zones for the main agro-export crops in the Piura hydrographic unit. Utilizing a Geographic Information System (GIS) and considering the bio-physical requirements of the crops, the research sought to delineate areas with high aptitude from both agroecological and socio-economic perspectives. Following the FAO's agroecological zoning methodology, various layers of spatial information were overlaid to define areas with specific suitability levels. Data were collected and analyzed from governmental sources such as SENAMHI, the Ministry of Agriculture, and the Regional Government of Piura to identify zones most optimal for each crop, closely approximating reality. The process included developing a Cartographic Model using the ArcGIS Model Builder tool, simplifying the creation of agroecological ...
