Abstract

The expansion of cocoa cultivation in the Eloy Alfaro parish of the Chone canton and its impact on natural vegetation cover has been the subject of study. Using Sentinel-2 and Landsat 7 satellite images, supervised and unsupervised classification techniques were applied to identify cultivated areas and their temporal evolution. Supervised classification allowed for a more accurate characterization of the crops. In addition, the analysis of vegetation indices showed that NDVI is a robust indicator for assessing the health of cocoa crops, presenting a high correlation with other spectral indices. However, the expansion of cultivation has resulted in a reduction in natural vegetation. The findings highlight the need to implement sustainable agricultural practices, such as agroforestry systems and efficient soil management, to balance cocoa production with environmental conservation.

Keywords: Cocoa, remote sensing, spectral indices, classification, sustainability.
