More research is needed to explain in more detail the high
levels of GAP dis-adoption in the Central Plains. A similar
survey could be conducted on a regular basis to determine
when adopters become dis-adopters and under what context
to be able to apply a dynamic framework (Barham et al., 2004;
D'Emden et al., 2008; Alcon et al., 2011). Panel data would also
allow us to identify the real impact of the project, in particular
to know whether the farmers who adopted Q-GAP were
already practicing cost reduction and appropriate use of
agrochemicals or not, and for how long. On a different note,
as it was shown that participation in Q-GAP is correlated to
labour constraints, the program promoters should propose
labour-saving techniques that would also help to comply with
the standards of production. In turn, this would pose new
challenges for the study of the adoption of inter-related
practices (Kassie et al., 2013).
