Analysis of irrigation water productivity in water scarcity context in the Bama rice farming plain, Burkina Faso

water productivity; water scarcity; rice farming plain; off-season, yield.Abstract
Nowadays, due to rain variability with a groundwater decrease, water resource became scarce in the main
irrigated plains in Burkina Faso. Thus, rice is gradually being replaced by other crops which have low water
need principally in Bama irrigated plain during off-season. This study aimed to analyze the efficiency of current
irrigation practices during dry season rice farming in Bama plain. Hence, fifteen peasant crop-production
practices in their plot of 0.5 ha during 2018 off-season from February to June have been followed. The irrigation
water supplied was much lower than rice water requirements, average 61% of ETR. In addition, 28.8% of the
yield has been determined by quantity of water applied with average water productivity of 0.8kg.m3.
