Kok et al. 2016 (https://pubmed.ncbi.nlm.nih.gov/26262912/) wrote an article about: A taxonomy of behavior Change Methods; an intervention mapping approach. In my research we used yhe Intervention mapping approach and developed a tool box with practical application to be used by the coaches for changing, working on specific behaviour. But it is a really extensive and thoroughly proces to go through. So there is no obvious answer to that question.
Besides that if you talk about motivation there is intrinsic motivation and extrinsic motivation. It is a proces to understand, what is happening, who have influence and what is the best approach in this case. All farms have their own unique social and physical context in which to operate. Interventions must fit in with these situations.
