Agroforestry system may be practised at three land ownership systems i.e. land belong to goverment, land belong to other person/company, and land belong to farmer. When the system is implemented in goverment land, farmers usually act as labour and only have  access to non timber forest products (NTFP). When the system is developed at other person, farmers besides has right to the NTFP, they also could sometime access to the threes depends on the agreement between them. When the system is practised at farmer's land, they have full access to the trees. However when trees are planted at farmer's land, the trees spacing is very narrow resulting the growth rate is very low.  Farmers mostly unwilling to thin the trees because they thought that by having more trees  they would have more benefit, even at very limited area of land.
