Cuba, the largest island in the Caribbean, is home to a number of significant rivers that are integral to its economy, ecology, and culture. The rivers of Cuba flow through its varied landscapes, including mountainous regions, fertile plains, and coastal areas. These rivers have historically supported agriculture, particularly in the country’s sugarcane industry, and continue to be vital sources of water for local populations. The major rivers in Cuba, such as the Cauto, the Almendares, and the Yumuri, have not only been critical for irrigation and hydropower generation but have also played roles in transportation and trade. This article explores the major rivers in Cuba, discussing their geographical features, cultural importance, and their roles in supporting agriculture and the environment.
