A delivery system constitutes a vehicle such as a printed leaflet or a web page which is used to communicate agro-ecological information to an end-user, such as a farmer (see Delivery system on the spiral), an implementation pathway is a necessary further step towards achieving an outcome. It usually involves some form of participatory social strategy such as farmer to farmer (“Campesino a Campesino”) which often includes the involvement of “farmers teachers”.
In this approach, on-farm workshops are a key part of this approach promoting an endogenous participatory social strategy, crucial for successful technology adoption by farmers (Lélé, 1991; Altieri and Toledo, 2011; Warner, 2007). Warner (2008) invokes Bruno Latour’s “circulatory system of science” as a theoretical framework for these types of social interactions (Latour, 1999). Such a methodological approach has been used in Central and South America (Altieri et al. 2011), Africa (Khan et al. 2000) and Asia (Altieri et al. 2011; Gurr et al. 2016). When farmers return to their communities after being involved in these on-farm interactions, they take part in horizontal participatory meetings (i.e. with peers) where their learned knowledge is propagated. Different authors claim that success in the implementation of different agroecological techniques is due largely to this participative approach (Altieri y Toledo, 2011; Altieri et al. 2011; Amudavi et al. 2009; Holt-Giménez, 2002; Warner 2007). For example, in Kenya, the push-pull procedure, developed by Khan et al. (2000) “pushes” pests out of crops and “pulls” it into a trap crop (Khan et al. 2011). Currently, 125.000 farmers deploy this agro-ecological technique (Khan, pers. comm.)
