Donkeys (Equus asinus) have played a fundamental role in the historical development of the Brazilian semi-arid region, particularly in transportation and subsistence agriculture. From the second half of the 20th century, factors such as agricultural mechanization, rural exodus, and loss of economic function led to a sharp population decline. There was a reduction of approximately 42% in the national workforce between 2006 and 2017, a trend also observed in the state of Alagoas. During this period, the local population decreased from 10,572 to 7,790 animals, with the Agreste region accounting for about 73% of the state’s decline. The study was based on the analysis of secondary data provided by IBGE for the years 2006 and 2017, allowing the identification of population dynamics and geographic distribution within the state. The analysis showed that municipalities of high economic relevance experienced reductions exceeding 80% in the donkey population, associated with urban expansion and the replacement of animal traction by mechanized systems. Although some municipalities presented occasional increases in animal numbers, this growth did not offset the overall declining trend. The study highlights the urgent need for public policies and sustainable management strategies aimed at donkey conservation, valuing their genetic and cultural heritage.
