The region is essentially agrarian in activity with rice, copra, casava, tobacco, timber and other crops. Rainfall is lower in the south of the Regency and higher in the north as the land rises toward Mount Rinjani. Rinjani supplies a rainfall catchment area to the region and several into eastern Lombok rivers flow from its slopes. The sea supports a small local fishing industry, seaweed harvesting, a pearl industry and prawn farming.
