Forest Based
Industries
Introduction
Agroforestry is a
potential approach to minimize unsustainable withdrawals from forests and instead promote
production of fuelwood, fodder and timber in conjunction with agricultural crops on
non-forests land. Highly adopted trees species have been identified for each agro ecozone
to encourage high productivity and diversify the products for use. Agroforestry is to be
promoted on wood catchment basis to support a large number of wood/pulp based industries.
Following are the major agroforestry systems, which are economically beneficial.
Some
Important Agroforestry System
The
poplar based agroforestry
system as proved more profitable over the most intensive cropping systems of rice-wheat in
the northern region. Poplars are an excellent source of fibres for various grades of
paper, fine paper, and packing papers and newsprint paper. Poplar wood is used for making
match splints, plywood, sports goods, toy, pencil-making, packing cases and crate-making.
Teak is one of the most popular and highly valued
timber trees. Attracted by the economic advantages of teak culture, many private companies
in India had ventured into establishing commercial plantations of teak. Teak tree is
graded in India as first, second, third, fourth and fifth quality as per the girth and
height attained at maturity (50-60 years). The market price of timber reduces
progressively from the bottom to the top end of the tree. The crown and branch wood of
trees is sold at about Rs. 1,000 per m3 as fuel wood. The average price of the
timber obtained for the entire tree can, therefore, be only about 20% of the highest price
obtained, for the best quality of timber.
Bamboo extensively traded throughout the country a
good quality bamboo of about 6-meter length and 18 cm girth sales for about Rs.30. In the
northeastern states bamboos are abundant commercial uses of bamboo are Bamboo
parquet (Block Flooring), laminated bamboo, bamboo reinforced concrete, artificially shape
bamboo viz. handicrafts, decoration items and cottage industries, and medicine. Also
bamboo charcoal in electric batteries. It is used in deodorizing fish oil in Asian
Countries.
Sandalwood yields maximum heartwood with a good amount of
sandal wood oil. The sandal wood oil is in great demand all over the world for its use in
perfumery products. Sandalwood is also in demand for use in perfumery products. Sandalwood
is also in demand for use in wood carvings. Sandalwood fetches a very high price, 1 kg of
sandalwood fetches an astronomical price of Rs. 1000 in the market. Apart from these
agroforestry system the most important multipurpose trees are viz. Populus deltoides,
Acacia spp., Dalbergia spp., Morus alba, Anthocephalus cadamba, Casuarina equisetifolia,
Prosopis spp., Bamboos, Grevillea robusta, Leucaena leucocephala etc.
Trees
in agroforestry systems are
used for making agricultural implements, furniture, bark yields gum/tannin, softwood,
mats, and thatches, turpentine and for oil purpose. The tree species in agroforestry can
be used for sericulture and apiculture also. Thus tree species in agroforestry systems are
useful for many forest-based industries. |
