Then, that requires a change of mindset, which is indeed, very difficult to bring about. And which perhaps will take a couple of generations to come.

And it requires farmers to reduce work on their fields, their prime source of revenue, given the opportunity cost of time.

Listing what has to be done is easy. But that is only a first step to solving the problem. The real challenge is to find ways of implementing them.

Well, you are right about that. But if changing mentality was an easy and timely process (because they also need to keep up with the technological pace), then I don't think countries in the world would be poor, in the absolute sense (because relatively, there definitely will be).
