Pérdida de cobertura vegetal y variación de la temperatura ambiental en Carpish-Huanuco, periodo 2022-2024
Objective: To evaluate the variation in monthly maximum and minimum temperatures associated with the loss of vegetation cover in the Carpish area, Huánuco, during the period 2022–2024. Methodology: Quantitative, nonexperimental, cross-sectional, and correlational design, using climate data from SENAMHI and satellite images (Landsat and Sentinel) to calculate the Normalized Difference Vegetation Index (NDVI) and analyze vegetation cover. Results: A sustained increase in temperature was observed: the average maximum temperature rose from 19.0°C in 2022 to 19.70°C in 2024, and the minimum from 11.0°C to 11.89°C. At the same time, vegetation cover decreased from 53,568 to 42,842 hectares between 2021 and 2023, representing a loss of 10,725.84 hectares. There is a very strong but insignificant negative correlation (-0.95; p=0.20) between temperature and vegetation cover; that is, as temperature increases, vegetation cover tends to decrease.. Conclusion: It was confirmed that deforestation directly contributes to rising temperatures.

Objetivo:Evaluar la variación de la temperatura máxima y mínima mensual asociada a la pérdida de cobertura vegetal en la zona de Carpish, Huánuco, durante el período 2022–2024. Metodología: cuantitativa, con diseño no experimental, transversal y correlacional, utilizando datos climáticos del SENAMHI e imágenes satelitales (Landsat y Sentinel) para calcular el Índice de Vegetación de Diferencia Normalizada (NDVI) y analizar la cobertura vegetal. Resultados: Se evidenció un incremento térmico sostenido: la temperatura máxima promedio aumentó de 19,0 °C en 2022 a 19,70 °C en 2024, y la mínima de 11,0 °C a 11,89 °C. A su vez, la cobertura vegetal disminuyó de 53 568 a 42 842 hectáreas entre 2021 y 2023, lo que representa una pérdida de 10 725,84 hectáreas. Existe una correlación negativa muy fuerte pero no significativa (-0.95; p=0,20) entre la temperatura y la cobertura vegetal; es decir, a medida que la temperatura aumenta, la cobertura vegetal tiende a disminuir. Conclusión: Se confirmó que la deforestación contribuye directamente al aumento de la temperatura.Descargas
