It is not just agriculture that needs discussion. Many youth, especially those with some skills or education qualifications, are concerned about the quality of health clinics, distance to hospitals and quality of education in rural areas. It is critical to take these into account when considering the goals and aspirations of young families. Capital access is probably next followed by having skilled persons nearby to make sure money spent is not wasted.
You may also want to look at Japan, Korea and USA where programmes for young farmers include skills training and access to low interest loans/start-up grants.
By the way, why did FAO cancel its programmes supporting national youth activities like 4H?
All the best,
