Patterns of Change in Irrigation and Land Cover in Western Bahia, Brazil

Abstract

My research quantifies the change of irrigation and land cover in nine municipalities in the western region of Bahia based on a time series of annual maps from 1985 to 2022. I wrote a computer program in the Google Earth Engine to compute the annual gross losses and gains of irrigated areas based on MapBiomas’ Collection 8 land use and land cover maps. The results allow us to understand the areas of natural vegetation or already existing agriculture being converted to irrigated agriculture.
