Three models of extension by farmer innovators in Burkina Faso

In the early 1980s, farmers in the Yatenga region of the densely populated Central Plateau in Burkina Faso developed a method of rehabilitating degraded land by improving the traditional planting pits known as zaï. Some of the farmers who have contributed to this development are also making great efforts to promote the spread of this technology. This chapter describes three extension approaches of farmer innovators – approaches that are, in themselves, innovations.
