When a multiple use water supply system is introduced in a water scarce area, livelihood options improve. A recent study in western Nepal, undertaken by the International Water Management Institute (IWMI) on the institutionalisation of MUS, showed that income from the sale of seasonal and off-season vegetables ranged from Rs 10,000 to Rs. 500,000 per year per household. Besides irrigation, MUS enables households to engage in other income-generating enterprises, such as animal husbandry, poultry, fishery, biogas and other small-scale productive activities.
