This study analyzes the farmers' practices and factors acceptability of supplemental irrigation from small pools of runoff collection (SIPW) on family farms of Sahelian and Sudano-Sahelian zone of Burkina Faso. The farming practices are evaluated using descriptive statistics with data collected from 629 farm households. Acceptability factors are determined through a logistic regression model. The results show that farmers' practices vary depending of the province within the same agro-climatic area. Most of the producers perceive changes in rainfall over the past two decades. The coping strategies are techniques for water and soil conservation, adoption of improved seeds and organic manure. However during dry season, crops remain subject to water stress caused by dry spells. For the majority of farm households, the SIPW is an alternative to mitigate the consequences of the dry spells. The acceptability ratio is estimated between 65 to 94% depending on province of agro-climatic zones. Farmers' decisions to practice SIPW are determined by eleven significant variables. Factors promoting the acceptability of SIPW in agricultural systems are marital status, farmers' perceptions of reduced rainfall events, practice of crop rotation and access to information. Constraints to adopt SIPW are illiteracy, use of improved seeds, farmers' perceptions of the frequency of flooding, expected usefulness of maize, sorghum and vegetables.
