If I want to, I could convert forest land for agricultural use2.22 ± 0.7613
Intention to convert forest land for agriculture
I will always clear forest land to expand the scope of my farming activities as long as I have the opportunity2.75 ± 0.53130.632
I have no reason not to clear forest land for agricultural purpose2.42 ± 0.5613
I am likely to clear forest land for agriculture soon2.37 ± 0.7213
