Forests are valuable assests to the nation. They provide timber,
fire-wood, forage and medicinal plants. These help in conservation of soil fertility and
thus enhance its productivity. They also provide the vital coverage to the country's water
sheds and regulate supply of water. They also sustain the country's wild life and provide
recreational facilities. These materials support and sustain such important industries as
paper, news prints, match, plywood, hardboard, pulp rayon, sports goods and a host of
cottage industries. Forests also induce better rainfall in arid regions.
Man's dependence on trees for the essential of his existence has been
of paramount importance in his life since the human race began. To-day almost all the
necessities of life are in one way or the other connected with the forest wealth. Besides
glorifying the beauty of nature, the trees prove to be helpful to the economy. The
economic growth of an agricultural country like ours is dependent on heavy plant
production and its wide distribution. The trees help the industrial revolution in a big
way and provide excellent raw materials for industry. The wooded area in our country is
4.5 percent of the total which is very insufficient. The universally desirable standard is
20 percent. Our annual requirement of wood is about 22 million cubic feet of timber and we
hardly produce 11 million cubic feet and the balance has to be imported in foreign
exchange. The total area of the country is 197 million acres, of which forest area
constitutes only about 72 lakh acres. Moreover, only 47 lakh acres or 2.4 percent of the
total has been classified as productive forests. It is estimated that with an increase of
50,000 acres per year in future afforestation programme, it will required about 100 years
to raise the present meagre forest area by about another 2.5 percent. Trees are beneficial
to mankind in many ways. They help to improve the environment. Trees can help to control
water and wind erosion, serve to regulate temperatures in the cropping zone, supply wood,
influence the cycling of nutrients significantly, fix atmospheric nitrogen, compete with
crops for light, water and nutrients, influence biological equlibria involving pests and
their natural enemies. Some woody plants such as Acacia arabica, Azadirachta indica,
Dalbergia sisso and Zizyphus mauritiana are grown in or on borders of the
cultivated fields, which have come economic values. As regards fruit bearing trees, we
have the example of our neighbouring country India. A large number of these trees live at
public roads and highways. Perhaps the tradition emanates from the earliest grand trunk
road, where shaddy trees, laden with fruit, were planted along the road for the benefit of
mankind. To plant trees is to ensure for the community unending social, economic and
environmental advantages. It is bequeath what our Holy Prophet (peace be upon him)
described as Sadqa-i-Jariya.
Unfortunately, ours is wood deficit country. Although, our efforts over
the past four decades have enabled us to increase the forest area from 2 to 5 percent, our
wood resources still lag far behind our requirements. We have to spend Rs.1.75 billion
every year on imports. Trees are like jewels strung around the earth. They add to the
beauty and glitter of our planet on the one hand and fulfil our innumerable needs on the
other. They add fragrance and colour to enliven the environment which motivates man
towards creativity. Like all other living beings, trees, too bow to Allah Almighty in
prayer and praise. It will, therefore, be sinful to pluck even one leaf unnecessarily.
That would affect the enviornmental balance of our planet.
No serious effort was made in the past to increase the number of trees.
A larger number were cut down, while fewer were planted. To-day, only five percent of our
land is dotted with trees. It is not enough to merely plant trees in fields and gardens
and on farms and orchards and along roods and canals. They have to watered, nursed and
protected till they are full grown trees. Many species are planted as ornamentals or shade
trees such as cordia obliqua, Acacia nilotica, Albizia lebbeck, Morus alba, Tamarix
ophylla and Dalberyia sissoo, mangifera indica, Tamarix aphylla, Zizyphus
nummularia. Some of the important trees species grown in Pakistan are poplar, mulbery,
Eucalyptus, Pinus radita, hard and soft wood tree species. Other trees are deodar,
Fir, Chir Spuree, Keo, Phulai, pine, Babool, Shisham, Lignum etc.
The average annual per hectare yield for the wooded forest are in
Pakistan is 0.21 cum. as compared to 1.65 cum. in case of UK and 1.19 cum. in USA. For
increasing potential yield and area the plants based on realistic strategy evolved are:
Management of forests on scientific basis, introduction of social forestry, Planning of
waste and denuded lands in high rainfall areas, raising industrial wood species on
suitable soil.
Raising and extension of nurseries to provide adequate plants to
planting agencies and farmers have been considered as essential attributes which need to
be implemented under strong and vigilant insight. Forests make an enormous contribution to
the environmental stability on the one hand and play a very significant role in food
security for millions of people on the other. A very important link between food
production and forest is the role of trees in keeping intact the fragile eco-system in the
watersheds as well as the low rainfall zones of a country. Excessive deforestation not
only causes soil erosion and disappearance of rich agriculture land but also because of
its effect on the water regime, is a major drought threat to the agriculture in the areas
situated downstream. Keeping in view so much significance it would be appropriate to say
that forest play an important role in the economy of the country. However, Pakistan is
extremely deficient in forest resources. The forest area for the last four decades has
remained almost static. Pakistan has nearly 4.5 percent of the area under forest. This
percentage is too low as compared with an optimum desired level of 20 to 25 percent.
A tree cover breaks the velocity of the raindrops before falling on the
ground, this substantially reducing the kinetic energy which is otherwise so great that
soil many times the volume of raindrop would be disrupted and eroded. Of all the natural
resources gifted to the mankind, sunlight, soil and water are the most important ones.
These resources have sustained the existence of man from the very beginning but in recent
years with increasing population, the demand of food has increased enormously. Out of the
total earth are of 510 million square kilometers, water is spread over 360 million square
kilometers making 150 million square kilometers of land available for man's use. The earth
receives about 10 million kilocalories of solar energy per square meter per year. Out of
this only 1 to 2 percent is absorbed by the plants and in turn, the net plant production
is about 0.3 percent of the light reaching the land surface. The optimum utilization of
natural resources in general and effect of forests in particular are of vital importance
to mankind.
In earlier times, when the rate of growth of population was very low,
man was free to utilize the natural resources wastefully. With the increase in population
and society becoming more industrialized and urbanized, man has no other alternative but
to put greater demands on natural resources, including water, land, vegetation, animals,
etc. causing cutting and encroaching of forests, increasing pollution and this disturbing
the ecological system. Although, Pakistan's forested areas are relatively small compared
to the land under cultivation and desert, the forests are of vital importance. Pakistan's
forests are of basic natural resource which provides food, fodder for cattle, fuel wood,
wood for building and other materials; they provide shelter and protection, and are source
of income and employment, providing oxygen to the air we breath and influencing the
climate. They protect the soil against erosion and help to prevent flood and
desertification.
Wood is an important source of energy and in Pakistan the shortage of
fuel wood alone presents an energy crisis for rural population which may be as profound
and intractable than that connected with oil. To day, Pakistan has only 4.75 percent of
the area under forests as compared to a desired level of 20-25 percent. There is a great
need for increasing forests for the betterment of the country. Wood is at present, mainly
used for construction, timber and fuel wood purposes. Only a small quantity is used for
manufacturing industrial carriages, boat building, pencils, coal mine timbering products
e.g matches, sport goods, plywood, particle board, bus and truck body buildings, railways
etc. However forestry as it exists today in Pakistan is generally characterized lack of
adequate area under forests, very low per capita consumption of wood and use of outdated
forest technology in planting and harvesting operations. There are a number of factors
responsible for this state of affairs. Firstly, Pakistan inherited a very small forest
area at the time of independence. Secondly, most of the land area in Pakistan is arid and
received low precipitation on which natural tree growth is not possible without artificial
irrigation. Further, in view of importance of agriculture, forestry development was given
low priority despite the fact that population has increased three-fold with the
concomitant rise in living standard of the people during this period. Research is
essential for the development of technology in any field which is suitable for local
conditions.
