Resumen
El presente trabajo está orientado a analizar los cambios en las coberturas de espejo de agua de la Laguna el Canclón ubicada en la Reserva Ecológica Manglares de Churute por medio de cálculos de NDWI y NDVI para los años 1986, 1996, 2014 y 2023 con el objetivo de conocer también el incremento poblacional alrededor de la laguna para poder determinar los factores antrópicos que pueden estar ocasionando la pérdida del espejo de agua se calculó el NDBI. Como resultado se obtuvo que durante el periodo de 1986 a 2023 existió una pérdida de 82,5 ha de espejo de agua. La mayor pérdida del espejo de agua se dio durante los años de 1986 a 1996, donde de 140,70 ha de espejo de agua disminuyó a 107,44 ha; en la actualidad la laguna cuenta con 57,75 ha, la vegetación sobre la laguna ocupa aproximadamente el 96,75%, es decir 774 ha, existiendo un aumento de la presión antrópica en las riberas de la laguna.
The present work is aimed at analyzing the changes in the water mirror coverage of the Laguna el Canclón located in the Manglares de Churute Ecological Reserve through NDWI and NDVI calculations for the years 1986, 1996, 2014 and 2023 with the objective to also know the population increase around the lagoon in order to determine the anthropic factors that may be causing the loss of the water body, the NDBI was calculated. As a result, it was obtained that during the period from 1986 to 2023 there was a loss of 82.5 hectares of water surface. The greatest loss of the water body occurred during the years from 1986 to 1996, where the water body decreased from 140.70 ha to 107.44 ha; Currently, the lagoon has 57.75 ha, the vegetation on the lagoon occupies approximately 96.75%, that is, 774 ha, with an increase in anthropogenic pressure on the banks of the lagoon.
