Conservation Of Forest Resources In North India Environmental Sciences Essay

Conservation Of timbers Resources In trades union India environmental Sciences Essay timberlands are intrinsic umbrellas for land surface because they protect the ground surface from erosion by falling raindrops and rig radiation respite of the earth and the atmosphere by consuming increased amount of nose candy dioxide released from ever change magnitude human volcanoes (chimneys of the detailories) and thus prevent the earth from nice too hot. Removal of woods coer exposes the ground surface to the atmospherical processes.woodland is a living resource. A large number of batch of the hills and plains depend on timber resources especially in the North- eastboundern Region of India. It is a renewable resource if properly managed. Dewoodlandation can take institutionalize in no time but generation of woodland takes a long time to develop into a self contained viable eco brass.Today, there is a great awareness of the jobs of timberlands in our country as easy as in N orth East India. During the last whiz ten the quality strand so forth forth of the region got depleted at an alarming rate, hence, conservation of quality is a heavy task for the region.Comprising of eight states, that is to say ArunachalPradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim and Tripura northeast India is a mega-biodiversity centre and a hotspot. The region contains more than one triad of the countrys total bio-diversity and is one of the 18 recognised bio-diversity hotspots of the world. It occupies 7.7% of Indias total geographic orbit supporting50% of the whole kit and boodle of which 31.58% is endemic. It is a transitional zone between the Indian, Indo-Barman-Malaysian and Indo-Chinese regions. The region supports a rich biodiversity spanning from tropical rain woods to alpine scrubs. This rich biodiversity has a significant bureau in the maintenance of the ecosystem.The region is rich in orchids, ferns, oaks bamboos, rhododendrons magnolias and so forthWith the shoplifting of commonality sell eachwhere, the region is also experiencing an impact on its ecologic system. The study threats to the rich biodiversity of the region are expansion of agri heathen activities, over-exploitation of afforests for lightingwood, shifting horticulture, encompassing timbering, grazing, urbanization, man-made forest fires, introduction of exoticplants, ill-managed road construction, mining, etc. which lead to habitat spillage and habitat fragmentation that ultimately results in biodiversity red. Natural calamities such as landslides, floods and forest fires also result in biodiversity evil to many extent. The region is known for its age old institutional mechanisms on cultural and social values for biodiversity conservation, namely divine groves or forests in Meghalaya, Manipur and Nagaland sacred graces in Sikkim and sacred hilltops in Arunachal Pradesh.Conserved as the abode of local dieties, these ecosystems match re mnants of ancient forests, but these practices are rapidly vanishing receivable to modern grooming and conversion of religion, which have led to the giving up of traditional and heathenish beliefs. India has strengthened its hold on biodiversity conservation by implementing the Indian wood Act, 1927 the Wildlife ( rampart) Act, 1972 the afforest (Conservation)Act, 1980 the Environment(Protection) Act, 1986 the Biodiversity Act, 2002 the Biodiversity Rule, 2004,etc.The northeastern lineament of India, known for its diverse and most all-embracing lush forest cover, is sadly one of the study regions facing strong deforestation. afforests of this region are unique structurally and species composition. It is a meeting region of temperate east Himalayan flora, palaeo-arctic flora of Tibetan highland and wonky evergreen flora of south-east Asia and Yunnan forming bowl of biodiversity. One of the states of this region viz., Arunachal Pradesh occupies a significant place as a cruc ible for the evolution of flora in northeast India and for speciation. The Brahmaputra valley sandwiched between Eastern Himalaya in the north, Garo/Khasi/Jaintia and Mikir/Cachar/Barail hills ranges in the south is a meeting ground of the temperate east Himalayan flora and the wet evergreen and wet deciduous floristic elements. The Khasi-Jaintia hills function as a corridor of the south-east Asia floristic elements into the Indian subcontinent through the Arakan arc. The altitudinal variation and rainfall patterns of southwest and northeast monsoon play a significant role in the nurture of ecologic niches in this region of India.The forest cover of atomic number 10 India has been assessed by the political science at 1, 64,043 sq. km of the total geographical battleground of 2,55,083 sq.km. In the states of north-east India the heaviest demand on forest is for fuel wood and agricultural lands. The precise of deforestation can non be accurately assessed due to the farawayness of many nations from which forest is removed and the lack of written records for deforestation. The forest neighborhood of the states like Assam, Meghalaya, Manipur and Mizoram has been reducing at an alarming rate. It is to be noted that the forest areas of the plains of the north-east India are considerably below national norm. In fact during the last few decades, there has become a rapid decadence of forest resources in the region which threatened the economy and ecology of north-east India requiring the intervention of the supreme court of India.According to an official estimate found on satellite images (survey write up of FSI), northeastern region has 1, 63,799 sq.km of forest, which is about 25% of the total forest cover in the country (Anon., 2000) The management of the forest has suffered in the recent past due to pressure on land, change magnitude cycle of shifting cultivation, exploitation of forest for timber and lack of scientific management strategy. The age-old practice of shifting cultivation has been a iodine factor responsible for the forest and land abasement, thereby changing the landscape extensively. About 0.45 million families in northeastern region yearbookly crop 10,000 sq.km forests whereas total area touched by jhumming is believed to be 44,000 sq.km (Singh, 1990). Degraded unessential forests, bamboo thickets and weeds or simply barren land dominate todays jhumscapes (Toky and Ramakrishnan, 1981 Roy and Joshi, 2002)Further, the problem has been getting worse through the indiscriminate felling of trees to satisfy the ever-growing hunger of industries surviving on forest products such as paper and pulp, plywood, match stick, etc. There is an urgent need of constitution measures to undo the massive losses to the green cover of this region. Unlike other regions of the country administrative control regimes of forest cover in northeast is different. A large part of the forests in this area fall under the category of open forests with a crown density of 10-40% and only few areas qualify as tiresome forests i.e. of crown density of 40% or higher. According to 1995 estimates, these states including Arunachal Pradesh, Assam, Meghalaya, Manipur, Mizoram, Nagaland and Sikkim accounted for a loss of 791 sq. km forest area in two years viz. from 1993 to 1995 (FSI, 1996).Administrative classification of the forest cover in Northeast India advance constitutionalReservedProtectedUnclassifiedTotalShifting gloss (1987-97)Tripura0.630.360.050.220.630.06Sikkim0.260.220.030.010.26*Nagaland0.860.010.050.800.860.39Mizoram1.590.710.360.521.590.38Meghalaya0.950.100.010.850.960.18Manipur1.500.140.400.961.500.36Assam3.071.810.400.863.070.13Arunachal Pradesh5.151.533.610.015.150.23Total14.014.884.914.2314.021.73 earth Use/Land Cover in Northeast India.

Quoted in statistical abstract, India, 2002,Forest cover in northeast IndiaA review of the forest cover statistics of northeast India reveals some unexpected and contrasted trends. Data from the Forest Survey show an increase in forest cover of 3,398 square kilometers, an annual rate of 0.5 percent, for northeast India between 1987 and 1991, and a potent reduction in forest cover of 2,443 square kilometers, an annual rate of 0.15 perc ent, during the 1991-2001 periods. This increase between 1987 and 1991 seems to contradict the general perception of steady forest loss during the last decades (Barik and others 2005 Roy and Joshi 2002).North East India Changes in Forest Cover 1987-2001 annual rate of loss of forest cover due to shifting cultivation in north-east IndiaStateArea affected by shifting cultivation in sq. km per year existence dependent on shifting cultivation(000)Arunachal Pradesh703270Assam700403Manipur500300Meghalaya760350Mizoram600260Nagaland730400Tripuraone hundred seventy100Source report of the forest survey of India,2001Percentage Annual Change in Forest Cover in North East India 1987-2001Ministry of Environment and ForestState-level data provide a clearer indication of the regional trends. The data reveal, for the period 1987-1989, a near 4 percent and over 5 percent increase in forest cover in Arunachal Pradesh and Sikkim take noteively. This seems implausible since natural regeneration process es are typically considerably slower. every bit improbable is the annual growing rate for Tripura, which is recorded at nearly 11 percent between 1999 and 2001.The reasons for this sudden expansion in forest cover are unclear, though it is suggested that the data reflect changes in methodological analysis and shell. For instance the 2001 data include all lands with a tree canopy density of more than 10 percent, irrespective of land use.Thus tea plantations, agro- forestry plantations, and fruit orchards are all defined as forests. In addition, a number of districts previously ignored have been included in the assessments, which probably leads to some increases. Hence the Ministry of Environment and Forests cautions against temporal comparisons as technique and descale of interpretation were both(prenominal) different (Ministry of Environment and Forests 2001).Open and Dense Forest Developments in North East India 1997, 1999 and 2001THE MAJOR CAUSES OF DEFORESTATIONConversion o f forest land in agricultural land Due to the increasing population and subsequent food pressure over limited agricultural land, forest land is been brought under cultivation so that agricultural production may be substantially increased and food may be provided to thirsty(p) human population.Shifting or jhuming cultivation Shifting cultivation is a major cause of forest lost in north-east India. The loss of forest cover due to shifting cultivation is increasing every yearOvergrazing of forest of moderate cover by animals has resulted into large scale degradation of natural vegetation if not the complete destruction of forest. The deforested areas has been belabor affected by grazing animals because no fresh regeneration of plant has been allowed by large herds of grazing animals.Forest fires Forest fire whether natural or man made is effective destroyers of forest covers. Atmospheric lightning is the major source of natural forest fires besides man causes forest fire through hi s intentional/advertent and unintentional actions. Besides destroying vegetations, forest fires indurate the ground surface which decreases the porosity of the soils and consequently there is a gnomish infiltration of rain water.Lumbering Lumbering for domestic and commercial purposes is the reliable cause of large scale destruction of forest cover. Ever increasing demand of timber for various purposes due to industrial expansion, urban growth and rapidly increasing human population has done great vituperate to natural forest covers.Multipurpose river projects Multipurpose river projects require larger areas to be submerged for the storage of huge volume of water in the reservoirs constructed nookie the dams. Thus, submergence of forested riverine areas completely destroys the natural forest.Steps taken by the governmentThe national forest policy of India, 1998, is now in force. Its expression has been timely and certainly a marked improvement over the policy of 1952, which em phasized on increasing the area under forest cover to 33% or 1/3rd of the country total geographical area and 60% in the hills of north-east India.Forest development substance (FDA) is a central agency which provides financial help to the state government for the planting of trees and conservation of forest area.The government of Assam has of late formulated a forest policy, developing a common approach to manage both environment and biodiversity. The new policy, 2004, which is first of its kind, seems to be a comprehensive careful one fuel, because the policy has considered almost all the major environment touch like flora and fauna, wildlife, soil fertility etc. the policy provides a comprehensive strategy for environmental conservation and improved support system for livelihood for the people living in the fringe areas of forests and thereby seeks to cut across the two major environmental problems- degradation of biodiversity and forest cover.CONSERVATION dodging of FOREST R ESOURCES IN NORTH EASTManagement of Biosphere Reserves, National Parks, Sanctuaries etc. in the region.Regulation of Sacred Groves.Introduction of more programs on Afforestation. possible Replacement of areas under Shifting Cultivation by alternative frugal activities.Ecosystem based forest management has to be adopted to maintain ecological balance.Reforestation in the deforested areas must be regulated to restore the ecological balance.Plantation of trees and vegetation should be made a compulsory deliver in educational institutes, Youth clubs and in communities.Areas of water-shed should also be managed through afforestation programs.Alternative Livelihood must be provided for forest dwellers.Over-exploitation, habitat loss and fragmentation are the three major factors that threaten the biodiversity of this region. Forest is the racy components to sustain the life support system on the earth.Forests are contend an important role in the socio-economic development of a country or region. The role of forest in ecological balance,Last but not the least, serious efforts will have to be made to protect and keep up forest both at government as well as public level. Due attention should be given to forest management. or so of the useful steps for the conservation of forest are as followsA proper ratio between forest cutting and plantation of trees should be maintained.Actual growth of trees is supervised.Strict prohibition of the cutting of trees for fuel is imposed.Protection from forest fire.Development of Natural Park and sanctuaries.Social forestry is developed.Forest survey, be conducted and classification be done accordingly.Plantation of trees according to local ecological condition.Long term master plan for forest conservation and development is prepared.CONCLUSIONEnvironmental stability, bio-diversity conservation, food security and sustainable development has been wide recognized at many aspects of conservation strategies. The key role of the forest has been recognized in their ecological, cultural, commercial and aesthetic aspects, yet rapid shrinkage of forest cover is threatening to tilt the ecological balance in the North Eastern Region. A sizeable disappearance of forest cover is ca employ serious damage to forest ecosystem of the region. The fast dwindling of forest cover is attributed to rampant encroachment and unchecked habitat expansion in the forest land. Encroachment is more aggressive in forest areas turn up along the inter-state boundary with Nagaland, Arunachal Pradesh, Assam and Meghalaya. For the Northeast the CDM funding potential can be maximized if the explanation allows for high crown density and height. Appropriate areas can be readily identified through comparative assessments of forest cover changes using the widely available aerial maps of the region. However, in the absence of an agreed definition it is impossible to quantify the financial opportunities that could emerge from the CDM. Further assess ments must dwell government decisionsMan has always had an integral association with nature, and thereby with forest. He has gradually changed the aspect of natural ecosystem into man-made ecosystem. Thus it can be said that man has the power too to control the further degradation of our natural environment if he desires to do the needful action and it would be possible only through the participation of man in respect of the preservation and conservation of various natural resources where, forest resource is one of the vital one. Hence it is worth mentioning that conservation of forest resources in North East India is need of the hour.
