Introduction
Biodiversity is a key global concern of the international community. The increasing species extinction rate is alarming for the future wellbeing of societies. Attention to biodiversity is important because people around the world are managing this biological diversity for plant cultivation, pastoral activities, forests and many other occupations. Good practices in protecting biodiversity are beneficial for the society in order to provide food, fuel and shelter as well as protect the biota and habitats for future generations (Jackson et al., 2007). Smallholder farmers are the guardians of both the biodiversity surrounding them and the knowledge to manage it (Altieri, 1987; Chevassus-au-Louis and Bazile, 2008).
