Plantation of trees on farm lands for industrial use is known as industrial agroforestry. Please check these links for more details.

Agroforestry techniques generally operate at one of three levels. The first level, and the one currently receiving most attention internationally, is agroforestry practiced by small farmers with the purpose of satisfying family or village-level needs. This may simply refer to one or two single-purpose eucalypts growing in the garden to supply part of the family's fuelwood needs or to half a hectare of Leucaena, a few of which are cut whenever a neighbour wants to pay or barter for some firewood. A relatively secure land tenure and tree tenure system is one of the best incentives for this level of agroforestry.

The second level of agroforestry (AF) is that promoted by local governments, usually on a fairly large scale. Taungya in its several modified forms is typical, whereby rural people are given incentives to plant trees along with their crops and care for them. At the end of 2-4 years, when the trees are well established and the crops begin to fail because of weed competition, soil nutrient depletion and shade from the trees, people are relocated to a new site and the land is allowed to go into fallow. Ideally the fallow period lasts until the trees are at the optimum point of maturity. They are then harvested and a new taungya rotation begins. The land and trees may belong to the people doing the work, but generally this is not so. Stability in tree and land tenure is provided by the local government.

This level of AF will fail with insufficient incentives or where the population-land ratio is too low or too high. When it is too low, farmers have enough free land to support themselves without a formal, government-operated system. When it is too high, fallow periods are necessarily too short for the land to recover and for the trees to reach optimum size for commerce or local use.

The third level of agroforestry has received very little attention in the literature, but is a highly promising technique. It consists of large-scale AF efforts, usually by the private sector. It is aimed at maximizing outputs (profits) on an industrial scale by the production of wood in combination with crops or livestock on a given piece of land. It may or may not have goals directed toward the benefit of local rural populations. It usually requires a secure land tenure system, the land being either owned outright by a large company or held in the form of a concession or a long-term lease. It may, however, also succeed under small ownership tenure patterns. This level of agroforestry is applicable to temperate as well as to tropical zones. Indeed, a form of AF has been proposed for the pine forests of the southern United States. Other temperate zone examples will be noted below.

Dear Suresh Raman

Industrial agroforestry could be a practice of agroforestry to meet the industrial requirement. The basic consideration in agroforestry is productivity, sustainability and adaptability. For example a farmer may think of going for agroforestry just to meet his requirement or he can take up AF for the sake of meeting the rwa material of an industry. For example in in Karnataka, Andhra Pradesh and Tamil Nadu states of in India many pulp and paper industries are approaching the farmers to cultivate pulp wood speceiswith buy back agreement to meet the requirment of pulp and paper industry. Such AF practices can be termed as Industrial Agroforestry.
