There is some research evidence from India that suggests that providing farmers with information and advice about the use of pesticides, high yield seeds, weather forecasts, etc is more important than ‘showing them what to do’. Farmers react more positively when you leave responsibility with them.
Of course, today the technology exists to provide advice and information ‘just in time’ via mobile phones. If an advice service can provide information on seeds as the sewing season start, it is much better than giving a lecture 6 months before the second starts.
In fact, this is a general principle.
Try to identify what information people need to be more productive and provide it in a convenient and timely form just as they need it.
