This study assesses the impact of supplemental irrigation from small man-made basins on cereal production in climate variability and change context marked by dry spells in the Sahelian zone of Burkina Faso. After two years, the experiments showed that this innovation in family farms increases maize yield and allows growing a second crop with the surplus of water available in the basin. At the end of the 2012-2013 campaign, the average maize yield was estimated 2.5t/ha on experimental plots (EP) and 1.7t/ha on control plots (CP). The average yield of the 2013-2014 campaign was evaluated as 3.3T/ha and 0.9t/ha for EP and CP respectively. Increase in yield is 0.8t/ha for the 2012- 2013 campaign and 2.4t/ha during 2013-2014. It appears as well as the yield obtained on EP in 2012-2013 and 2013-2014 for bridging cereal need of 2 and 6 additional persons respectively in agricultural households compared to the CP. The review of the Net present value, internal rate of return and the Net benefits increase ratio show that the profitability to practice supplemental irrigation depends on the types of basins.
