Improved irrigation methods – In Daojie, the high
clay soil content of some fields can hold water longer,
so the villagers make small water tanks and channels
along their fields to store extra water during the winter
irrigation season. The channels enable them to direct
water to the roots of the crops for water saving. Some

planned collectively. Since the start of HRS, individual
households could respond to water stresses by adjusting
farming and livestock management decisions and doing
off-farm work. However, these common responses may
vary depending on the impacts felt, the consequent
responses, and the individual household’s socioeconomic
situation. The following strategies have evolved over time
to address water availability.
Changing crop variety and cropping patterns – In
