The seasonality of rainfall, maximum and minimum air temperature, relative humidity, wind speed and solar radiation impact the ecological status of the Apacheta micro-basin. The objective is to estimate the seasonal stages from climatic parameters measured at the Apacheta micro-basin weather station, based on the selection of intervals of precipitation values. The rainy season includes the months of January, February, March and December, its precipitation is 145.96 mm with maximum air temperature of 12.3 °C, minimum air temperature of 1.55 °C, relative humidity of 74.04 %, wind speed of 2.6 m/s and solar radiation of 527.13 Ly. The intermediate stage in April, September, October and November, with precipitation of 51.89 mm with maximum air temperature of 13.38 °C, minimum air temperature of -0.2 °C, relative humidity of 69.76 %, wind speed of 2.96 m/s and solar radiation of 552.37 Ly...

El decreciente caudal de salida en la microcuenca Apacheta, observado durante el periodo 2000-2018, afecta de manera directa el almacenamiento de agua en la presa Cuchoquesera e impacta, de manera negativa, en la demanda para consumo humano y agrícola, muchas veces por encima de su disponibilidad hídrica, así como en el buen estado ecológico de la microcuenca. A largo plazo, este problema puede intensificarse a consecuencia del cambio climático. El objetivo del presente estudio fue evaluar la tendencia anual del caudal de salida en la microcuenca Apacheta, así como pronosticar valores futuros, en referencia a su caudal ecológico de 2.24 m3/s y su sensibilidad en el momento de satisfacer adecuadamente las diferentes demandas. Para ello, se combinaron datos hidrometeorológicos, información satelital y el modelo PRMS-IV. Nuestros resultados indican que, de continuar la tendencia an...

Agricultural production of Citrus x limon (lemon) and Mangifera indica (mango) in the Piura region is often affected by environmental-climatic factors, mainly by possible seasonal changes or extreme weather events, such as droughts or El Niño. The objective is to analyze the spatial-temporal agricultural production of lemon and mango, measuring with the FieldSpec4 spectroradiometer, the spectral signature (SF) and Sentinel 2 satellite images (ISS2) of the Chulucanas criollo mango in crops of Pampa Larga-Alvarados-Suyo-Ayabaca and INIA-Hualtaco-Tambogrande-Piura mango germplasm bank, respectively. The method consists of entering each EF in the ISS2 (2019) mosaic of tiles 17MMR-17MNR-17MPR-17MMQ-17MNQ-17MPQ-17MMP-17MMP-17MNP-17MPP, using SEN2COR280 in SNAP software. The time series of monthly/annual production of lemon and mango were analyzed using data from INEI and SIEA-MIDAGRI-PERU. Th...
