Guwahati being the lone city of North eastern portion, the metropolis witnessed various alterations like rapid addition of populace, depletion of forest display screen, spread of diseases which will resulted various environmental careers akin to collection down, atmosphere, H2O and society.
Most of the alterations took topographic point due to the effect of changing natural environment, substantial growing of population peculiarly after moving over of the capital from Shillong to Dispur, hill tend destabilization because of building of roads, brooding houses, general public establishments and besides intended for invasion in wetlands and low resting countries.

Primary informations were gathered by topographic point go to and immediate observation from the phenomena. One the other side of the coin manus supplementary informations have been collected from assorted published plants just like books, diaries research content articles, studies etc . Topographical roadmaps ( Simply no 78N/12 , A, of sixteen ) and satellite creativeness ( PLACE MLA P-238, R-298 Dated 18/10/1990 and Landsat TM P-137, Ur -042 Went out with 10/06/1988 ) have been utilized to analyze the nature of the town growing, be familiar with environmental concerns and to happen out alternatives for minimising the wretchednesss of the locale inhabitants.
Collected informations have been summarized, analyzed and offered in various signifiers like graphs, tabular arraies, maps etc . for easy apprehension from the content of the paper.
Data Analysis and Findingss
1 ) Locational distinctive feature of the metropolis invites various environmental jobs. Back in show the city was referred to as Pragjyotishpur, which finds reference in Mahabharata, Ramayana, Raghuvansha of Kalidas.

While using weakening of Ahom electrical power in Assam, the town passed in the custodies of British in 1826. Throughout the British yearss political pre-eminence of Guwahati shifted to Shillong, that they can chose because State Capital. In 1971 with the reorganisation of Assam State and switching of capital to Guwahati ( Dispur ) it once more reclaimed its personal pre-eminence in north east part [ one particular ]#@@#@!. Since therefore Guwahati has made a rapid progression every bit far as market, commercial and industrial activities are concerned. Each one of these activities are in charge of for many environmental jobs in the metropolis ( Fig. 1 )..
installment payments on your Geographic and geological apparatuss are responsible to a great extent for the jobs like water-logging, landslide etc . in the locale. The general kind of the metropolis is merely just like a bowl surrounded by hills and knolls in three edges and riv side streets on the being side. The peak in the field countries of the town varies from forty-nine. 5m to 55. 5m.. There are a number of little knolls in the metropolis which Sarania ( 193m ), Nabagraha ( 217m ), Nilachal ( 193m ), and Chunsali ( 293m ) are of import. The slopes are composed of Granite, Quartzite, Hornblende-Biotic-Schist, Pegmatite and Quartz. On the other manus the discipline countries in the metropolis have
old and new alluvial sediment. Many portion of the metropolis consisting of light yellow to ruddy dirt. If the dirts wholly H2O condensed during the monsoon months speed up the rate of landslide jeopardies. The flinty stones on the hills gradually exposed due to hill dirt eroding. Often rock show up occur during the end portion of the monsoon months and take valued human lives and injury belongings. Seeing that August 1987 to September 2005 every bit many while 22 instances of landslide and stone slide instances documented in different locations of Guwahati.
3. Climatic status peculiarly rainfall attentiveness in monsoon months from June to September do many incommodiousness like water-logging, dusty atmosphere, spread of H2O paid for and air-borne double daggers. Normally June rainfall is definitely ever bitter but the cloudburst absorbed by simply dirt. With this phase landslide, stone fall months and WATER logging and so forth make low originate. Although from Come july 1st onwards in each hefty shower cause H2O logging in the countries like Narengi, Satgaon, Saimail, Khanapara, Noonmati, Bamunimaidam, Chandmari, Silpukhuri, Guwahati Club, Uzanbazar, Panbazar, Fancy Bazar, Paltan Bazar, Athgaon, Bharalumukh, Maligaon, Adabari, Jalukbari, G. T. Road, Tiergarten Road Tinali, Rajgarj Street, Bhangagarh, Dispur. When slope soils become concentrated landslide and rock autumn take place. Again, immediately after INGESTING WATER logging, course surface become boggy and roadside drains clogged with silt based on the hillsides. Soon after, dry out clay within the roads make dust-covered mood and maximize air pollution. Furthermore, storm WATER cause commixture of drain H2O and infected armored combat car wastewaters with imbibing INGESTING WATER beginnings worsen the wellbeing jeopardies in the metropolis.
4. Almost all the roles of the city related to the citizenry growing. The decadal developing of human population in Guwahati Metropolitan Expansion Authority ( GMDA ) clearly indicates how human population may make opportunities in the city ( Table- 1 ) The city conurbation map since 1911 besides bespeak how city has been expanded ( Fig-4 ). It has drastically altered the land usage kind in the town ( Table-2 ). More peculiarly slums and homesteaders have improved manifold in last few older ages. As a consequence many incommodiousness and jobs have arisen in the town.
5. Substandard planning and blank in put to deathing the development strategies aggravate the jobs in the locale. In this respect, bumpy route infinite, deficiency of auto parking installation, undersized wayside pumps out, randomly established public-service organization wires and pipes are deserving adverting. Almost all the of import roads, viz. GNB Road, GS Street, MG Road and most of the traffic stage face cachectic fever traffic congestion. About 1975 the figure of motorised cars in the locale was merely 27, 1000 which has elevated to 1, up to 29, 856 in the twelvemonth 1990. After that the rate of addition accelerated through 2003 that records three or more, 13, 387. As such around one hundred thousands of motor vehicle included with the highways of Guwahati every twelvemonth [ 2 ]#@@#@!. On the other manus the metropolis nation has increased by merely 46 sq distance in last 20 aged ages. Most of the streets inside the metropolis are merely 4. 8m broad. There are numerous lanes, which have merely several. 6m or maybe 3. 0m breadth. Thesiss should be for least eight. 0m to get visible the radiation and channel vehicles and at least on the lookout for. 0m for heavy vehicles [ 3 ]#@@#@!. The results of the vehicular emanation demonstrate misdemeanor in emanation certain by 53 per centum and 81 per centum in instance of gasoline and Diesel powered vehicles severally [ 4 , A, your five ]#@@#@!. It evidently indicates the magnitude of pollution level in the metropolis.
6. Insufficient consciousness and inclination of go againsting the best practice rules and restrictions in building houses, disposing family waste materials and staying targeted traffic regulations trigger many jobs inside the metropolis.
several. Inanition in implementing Torahs besides responsible for the jobs of traffic congestion, garbage disposal, hill incline destabilization, wetland invasion and assorted types of pollution in the town.
