Forest Resources
Use and overexploitation
• Scientists estimate that India had 33% of its land under forests (today we have only about 12%)
• Not only to protect existing forests but also to increase our forest cover
• People who live in or near forests know the value of forest resources
• Water we use depends on the existence of forests on the watersheds around river valleys
• Our homes, furniture and paper are made from wood from the forest
• We use many medicines that are based on forest produce
• We depend on the O2 that plants give out and removal of CO2 breathe
• Forests once extended over large tracts of our country
• As agriculture spread the forests were left in patches which were controlled mostly by tribal people
• They hunted animals and gathered plants and lived entirely on forest resources
• Deforestation became a major concern in British times when a large amount of timber was extracted for building their ships
• Alienated local people by creating Reserved and Protected Forests, which curtailed access to the resources
• Another period of over utilisation and forest degradation occurred in the early period following independence as people felt that now that the British had gone they had a right to using our forests in any way we pleased
• Timber extraction continued to remain the Forest Department’s main concern up to the 1970s
• Forest degradation and deforestation was creating a serious loss of the important functions of the forest began to override its utilisation as a source of revenue from timber
Deforestation
• Where civilizations have looked after forests by using forest resources cautiously, they have prospered, where forests were destroyed, the people were gradually impoverished
• Today logging and mining are serious causes of loss of forests in our country and all over the world
• Dams built for hydroelectric power or irrigation have submerged forests and have displaced tribal people whose lives are closely knit to the forest
• One of India’s serious environmental problems is forest degradation due to timber extraction and our dependence on fuel wood
• A large number of poor rural people are still highly dependent on wood to cook their meals and heat their homes
• We have not been able to plant enough trees to support the need for timber and fuel wood
• National Forest Policy of 1988 was started
• Another resolution in 1990 provided a formal structure for community participation though the formation of Village Forest Committees
• Based on these experiences, new guidelines were issued in 2000
• This stipulates that at least 25% income from the area must go to the
• From the initiation of the program, until 2002, there were 63,618 JFM Committees managing over 140,953 sq. km of forest under JFM in 27 States in India
• Timber extraction, mining and dams are invariably parts of the needs of a developing country
• If timber is overharvested the ecological functions of the forest are lost
• Unfortunately forests are located in areas where there are rich mineral resources
• Forests also cover the steep embankments of river valleys, which are
• Thus there is a constant conflict of interests between the conservation interests of environmental scientists and the Mining and Irrigation Departments
• What needs to be understood is that long-term ecological gains cannot be sacrificed for short-term economic gains that unfortunately lead to deforestation
• These forests where development projects are planned can displace thousands of tribal people who lose their homes when these plans are executed
• This leads to high levels of suffering for which there is rarely a satisfactory
FOREST FUNCTIONS
Watershed protection:
• Reduce the rate of surface run-off of water
• Prevent flash floods and soil erosion
• Produces prolonged gradual run-off and thus prevent effects of drought
Atmospheric regulation:
• Absorption of solar heat during evapo-transpiration
• Maintaining carbon dioxide levels for plant growth
Erosion control:
• Holding soil (by preventing rain from directly washing soil away)
Land bank:
• Maintenance of soil nutrients and structure
Local use
• Consumption of forest produce by local people who collect it for subsistence – (Consumptive use)
• Food - gathering plants, fishing, hunting from the forest
• Fodder - for cattle
• Fuel wood and charcoal for cooking, heating
• Poles - building homes especially in rural and wilderness areas
• Timber – household articles and construction
• Fiber - weaving of baskets, ropes, nets, string, etc
• Sericulture – for silk
• Apiculture - bees for honey, forest bees also pollinate crops
•Medicinal plants - traditionally used medicines, investigating them as potential source for new modern drugs
Market use - (Productive use)
• Most of the above products used for consumptive purposes are also sold as a source of income for supporting the livelihoods of forest dwelling people
• Minor forest produce (non-wood products): Fuel wood, fruit fiber, etc
• Major timber extraction for construction, industrial uses, paper pulp, etc.
• Timber extraction is done in India by the Forest Department, but illegal logging continues in many of the forests of India and the world
Summary
