Irrigating rain-fed areas is expected to lead to higher average yields, essentially changing the production technology in a manner that allows more intense production. The amount of land converted to irrigation was calculated by assuming that the water used to irrigate the newly converted land would match the amount of water “saved” as a result of improved water reliability in the first irrigation scenario. However, due to water constraints in some regions, it may not be possible to maximise yields in irrigated areas due to greater demand for water from other users.
