Agriculture is indeed a good way to employ yourself because it is easy but sometimes risky because the crops may not produce well.
But it's good to hear that agriculture is the best way to employ people in your country though is is stressful and pay little but at least it's still better than to stay idel.

By learning trade skills the rate of employment will be reduced in your country.
