**Abstract**

Agriculture is the main source of income for the poorest people and the pillar of food security in Burkina Faso. However, the producers face the problem of food insecurity each year, due to the effects of climate change and the difficulty of conserving their produce, because of inadequate storage infrastructure. These situations result in the loss of large quantities of products after harvest. Technological advances can provide solutions to this problem of postharvest losses and help many small producers to reduce poverty. Unfortunately, new product conservation techniques implemented in Burkina Faso are less known and poorly adopted. The objective of this chapter is to identify constraints to the valorization of new postharvest technologies of onion and potato and analyze factors influencing farmers' perception of these innovations. The results of the surveys conducted using the Tilgr-Baore technology show that many agricultural producers are analphabet and not yet aware of the existence of the new product conservation technology. The improvement of the level of education of farmers and the availability of information on innovations are needed to improve the perception of innovations and thus increase the probability of adoption of these innovations.
