As a hydraulic empire, the Ajuran monopolized the water resources of the Shebelle and Jubba rivers. Through hydraulic engineering, it also constructed many of the limestone wells and cisterns of the state that are still operative and in use today. The rulers developed new systems for agriculture and taxation, which continued to be used in parts of the Horn of Africa as late as the 19th century. The rule of the later Ajuran rulers caused multiple rebellions to break out in the empire, and at the end of the 17th century, the Ajuran state disintegrated into several successor kingdoms and states, the most prominent being the Geledi Sultanate.
