Human Effects On Environment

Human Effects On Environment


Aim: To investigate on the ways of conservation of the environment of IIT campus by the people.
Hypothesis :->

 IIIT Madras is a residential institute that occupies a 2.5 km² campus that was formerly part of the adjoining Guindy National Park. The institute has nearly 550 faculty, 8,000 students and 1,250 administrative and supporting staff. Growing ever since it obtained its charter from the Indian Parliament in 1961, much of the campus is a protected forest, carved out of the Guindy National Park, home to large numbers of chital (spotted deer), black buck, monkeys, and other rare wildlife. A natural lake, deepened in 1988 and 2003, drains most of its rainwater. 

Vegetation   in   iit madras :->
vIt is apparent that the original vegetation of the campus was of the southern thorn forest type. This forest type is dominated by the thorn and cactus like plants that produced milky latex.

vStructurally these forests were patchy with grasses and herbs dominating the land that was adorned with widely spaced thickets. The predominance of ficus trees indicates that campus had a long history of human impact. This forest type is dominated by the thorn and cactus like plants that produced milky latex.


vThe size of other common trees suggests that the transformation from the original to the present vegetation type has taken place in the last 50 and 100 years.





Wildlife in  iit madras :->
  • vFifty species within a small area as IIT-M is comparatively much higher than the 64 species known in the entire British Isles ! A number of species of plants that occur on the Campus (including the garden plants) are food plants for the larvae of butterflies.
  • vMany like Pavetta indica attract adult butterflies. Notable butterfly species of the campus include the spectacular Common Banded Peacock, Great Orange Tip, Common Jay, Common Bluebottle, Crimson Rose, etc. Frogs, toads, lizards, snakes and tortoises /turtles are also diverse.
  • vThere are a number of pools where the frogs are breeding (a very healthy sign indeed). That the Fan-throated Lizard (see photo) continues to survive on the Campus is also remarkable. 
  • vFifty-one species of birds on the Campus suggests that the habitats are not quite suitable for the feathered animals. Even if the migratory and stray visitors are included, the list is not likely to go beyond 80 species. Many species of birds like the Redvented Bulbul, Black Drongo, Common Iora, etc., are in alarmingly low numbers.
  • vThere are between 130 and 150 Macaques at present that move around the human dominated zones of the Campus in troupes of 10-15 animals. Their ability to adapt to (and exploit) the available habitat and carelessly disposed food will further increase their numbers leading to serious conflicts with people and other species of animals on the Campus.

  • Unlike the Macaque, the Chital spends more time within the Wilderness Zone. The critically endangered Blackbuck has a population size of 12 (4 males and 8 females). The biggest hindrance to its continued survival is the rapid loss of habitat - open scrub and grasslands.   


Prakriti   (wildlife  club) :->

      Prakriti, the Wildlife Club of IIT Madras, Was founded in April 2002 by a group of wildlife enthusiasts comprising of students, faculty, staff, residents and alumni of IIT Madras. The formation of the club was spurred by a growing recognition of the need to protect the unique biodiversity of the IIT Madras campus. The IIT Madras Campus was carved out of a natural forest that formed part of the Guindy National Park. The Guindy National Park and IIT Campus come under Tropical Dry Evergreen Forest type - the least common vegetation type seen in India. The campus can be considered as an ideal example for the co-existence various types of mini-ecosystems. The main inhabitants of these ecosystems are the blackbuck, spotted deer, jackals, mongooses, monkeys, squirrels, toddy cats, wild cats, various types of reptiles, a plethora of insects including about 40 different species of butterflies and about 100 species of birds. IITM campus also hosts large groups of migratory birds and butterflies every year. People can approach the club members for any emergencies or issues related to the wild life of the campus.


Wild life  help-lines :->
1.                When  hit  by  a  vehicle :
Do not go near and make the animal panic unless you know some first aid. Call the Veterinary Doctor (Dr. Kribakaran is a vet who comes on the spot and examines/treats the animal. He is also an expert on treatment of wild animals). Please do not try to transport the animal unless the doctor says so. Most of the wild animals like deer and black buck can die due to shock while transporting as well as mishandling of the injured animal. If the doctor is not available, call the Blue Cross Try to discourage formation of crowd around the affected animal Injure deer should not be kept on cement/smooth floor since they can break their legs while trying to get up and slipping (It is difficult for animals with hooves to balance on smooth surfaces).
Emergency numbers :

Dr. Kribakaran : 24471743 (you will also have to pay the doctor's bill or call one of the following IIT numbers and inform and has to be around when the doctor arrives to guide him to the injured animal) 

Blue Cross Ambulance : 22354959 

Prakriti members: 4172 or 6172 or 6419 or 4169 or 6169 or mobile: 9884278466

2.             Animal death :
Inform the Wildlife Department. Inform the Security Office, IITM.
Emergency numbers :

22301328 (Range Officer, Guindy National Park) 

24321471 (Wildlife Warden) 

8280 (Security Duty Officer)

3.              Prevention  of  cruelty  towards  animals : 
 Please do not interfere if you notice two animals (of the same species, like two male deer or two male blackbuck or two male monkeys, snakes etc.) fighting. It is natural. They are trying to establish territory by doing this. Similarly, the male Spotted deer sheds its antlers (these are not horns) every year. Do not panic when you see the exposed skin and little bleeding, after the antlers fall off. This will look as if someone has cut it. In comparison with deer, the male blackbuck has permanant horns. They will not fall off. If you see anyone throwing stones or using catapults at animals/birds, or trying to catch them or putting traps/snares etc. in the campus or ill-treating animals, inform the Security office or the wildlife officers. You may also contact Prakriti volunteers if you need help.
Emergency numbers :

8280 (Duty room), CSO (8262 or 9262) or Prakriti members (4172/6172, 6419, 4169/6169).

Work-plan   and   methodology :->

Our plan was to collect as many photos as possible, conduct surveys in the campus, observe the natural beauty inside the campus, conduct an investigation in the heritage centre, enquire about garbage disposal and other queries in the owzone garbage duct. Fortunately, we managed to complete the whole plan. On the first two days we went to the residential zone to conduct surveys. Then we went for a nature walk and collected many pictures. Then we went to the heritage centre and observed the nature through photographs and posters. Atlas we went to the owzone garbage duct and had a conversation among the staffs and also got to know about the garbage disposal and its machinery.  


How  can  we  protect  species  in  our  campus 

                  `         Maintain their habitat area as open grasslands and avoid planting more trees in this area. Trees will not allow grass and herbs to grow, on which the blackbuck survive. Details of the blackbuck habitat area are shown on the campus map.
     Avoid construction and concreting, especially in the blackbuck habitat area. This is increasingly reducing the food availability of these animals. This area is heavily built up (about 25% including concreted and paved surfaces) and fragmented due to buildings coming up in key habitat zones dividing them and making them not accessible to animals.
      Protecting trees alone will not help humans as well as other animals who feed on the ground. A habitat is healthy due to various species that exist there in harmony. Protect bio-diversity by protecting the native wild plants and trees 
     Refrain from creating fences on campus. Take pro-active steps to remove fences around your buildings. This will increase the habitat area for animals
     Drive carefully and slowly in the campus. There have been many cases where Blackbuck and Spotted deer were killed by vehicles. Instruct drivers if you are using taxi/auto etc.
      Do not throw cooked food remains in open bins as this encourages stray dogs.
     Avoid creating lawns and return the existing lawns back to nature to recover native species.

In  order  to  improve  the  quality  of  habitats (with  the  Blackbuck  in  view  as  the  Flagship) and  restore  at  least  some  areas  into  the original  vegetation  type,  the  following  steps have  to  be  adopted :

      Systematically weed the open spaces in the Campus of invasive plants such as Prosopis juliflora (saplings), Cassia siamea (saplings), Cassia javanica (saplings), Cereus peruvianus, Antigonon leptopus and Croton bonplandianus.

      Remove all Prosopis juliflora trees and the cactus (Cereus peruvianus) from grids A16-G16, H17, K12 and K13 and restore the habitat using native grasses, bamboo and shrubs.

      Protect the Lake and swamps by planting bamboo along the periphery.
This will particularly help in minimizing the pressure  on the Lake  from  
people living in areas adjoining the Campus.

      The space between the newly constructed Boy's Hostel and the Student's Activity Centre (Hostel Zone; grid no L15-M15) that has been cleared and reclaimed should not be planted with trees or lawn grass. Instead the empty space should be restored using a combination of native grasses and bamboo.

      Over-shading by excessive tree growth has been the bane of IIT-M. Curtail the planting of trees on the Campus. Native grasses should be allowed to take-over all open spaces. There are at least 29 species of native grasses on the Campus that can be used for the purpose.

Waste  disposal (ozwone  grean  plant):->

COLLECTION OF GARBAGE FROM THIS SOURCE ITS DISPOSAL METHOD :

1. Two plastic buckets were given to each flats. One green bucket used for bio-degradable waste. The segregation of the garbage starts from the individual house.
2. Garbages were collected in two separate big plastic dust bin used for bio-degradable and non-biodegradable waste by the zero waste zone workers (on contract basis) daily in the morning from the residences using tricycle.
3. The collected garbages are taken to the segregation yard.
SEGREGATION OF COLLECTED GARBAGES :

1. The IIT Madras campus has been divided into three zones named residential zone, academic zone and Hostel Zone.
2. The solid waste management deals with the efficient disposal of sewage, drainage water and the garbages.
3. The collected garbages from all the zones were taken to the segregation yard for further segregation.
4. The garbages were segregated a usable and non-usable item

5. The usable items like glass bottles, papers, bags, card board, plastic bottles, polythene covers, pet bottles etc. were separated and given for resale.


Observation :->

1.            By visiting the heritage centre we observed many species of plants, birds, animals, butterflies, toads etc. we could also observe the natural beauty of the campus and its ecology.

2.             By taking surveys, we got to know the opinions of the residents of iit campus and their disposal methods.

3.            By visiting the ozwone garbage duct, we learnt about garage disposal, recycling and other queries. We could also obtain that the food remains of the campus is converted into organic manure.

4.            The residents segregate their household garbage into 3 bins – recyclable, non- recyclable and other materials like sanitary napkins.

5.            A wild life organization called prakriti is incharge of the wildlife and its security. It’s also an adjoining part of guindy national park.

Conclusion :->
We successfully, completed our investigatory on time with our satisfaction. We learnt and discovered new things. We also understood that we should always know about our environment, its components and its conservation. So we salute the people who care for our environment and take its responsibility.



Acknowledgement :->


We sincerely thank our science teacher, Mrs. Nandhini mam, for giving us the opportunity to carry out the study, observation and learning of new knowledge inside the campus and for the overall encouragement. We also wish to place on record our appreciation of the cooperation and services extended by the owzone staff members, heritage centre staffs and the residents who have helped us a lot. Our sincere thanks are indeed due to the principal and baghyalakshmi mam, who helped us to visit the heritage centre.
