Mumbai

7/28/2014 3

• Mumbai developed by British

and nurtured by Local

Mumbaikars.

• Earlier comprised of 7 isle now a

metro city

• Financial capital of the country

• Busiest and 1 of the rapidly

growing city in world.

Navi Mumbai• Navi Mumbai is being developed as a counter

magnet to the main city to achieve the goal of

de-congestion of Mumbai

• CIDCO developed a new town Navi Mumbai of

area 344 sq. km.

• Its Asias largest planned and developed city for

population 2 million and 0.8 million jobs.

• high-tech Jawaharlal Nehru Port (JNPT)

catering to International Container Cargo

traffic at Nhava-Sheva is located on the

southern side of the city.

7/28/2014 4

Need of NMIA project?• Mumbai contributes about 40% of total net domestic product of Maharashtra.

• The share of manufacturing sector employment is expected to decline from 35

% to 27% and share of tertiary sector employment is expected to increase from

64% to 72%.

• City is shifting from traditional manufacturing activities to trading and service

activities.

• There is a need of increasing the capacity of airport as the existing Sahar airport

(domestic) and CSIA (international) are not sufficient.

7/28/2014 5

• Mumbai handles (23%) caters for the highest air

passenger

• Mumbai airport at Santacruz is the busiest airport in the

country and handles approx. 23% of total passengers, 31% of

Cargo traffic and 18% of aircraft movement in the country.

Navi Mumbai site

• Located near Panvel town about 45 kms from the

CBD of Belapur.

• 2 runways are planned. Phase wise development is

adopted to meet the air travel demand.

• The site is also proposed to be accessed from Mumbai

by high-speed water transportation system abutting

airport site.

7/28/2014 6

Location and Geography• Located at Panvel taluka, Raigad Dist.

Maharashtra.

• Present site is majorly CIDCO owned and

remaining is private which will be acquired

for airport development.

• SH54, NH4B, Aamra Marg (Running on the

Boundary of Airport site).

• Panvel creek, Gadhi river, Taloja river and

Ulwe river running along and through the

boundary of the airport.

• Ulwe hill – RL 82 Mts. within the site.

• Elephanta at a distance of 13 Kms. West

• Seismic zone :Zone-III as per IS: 1893 (Part-I)

2002.

• Study area falls in coastal region of Konkan

area.

• Panvel 1.5 kms. on Central Rly./Konkan Rly.

Khandeshwar – 1 km. suburban Rly..

7/28/2014 7

The study area is about 10 kms

in radius around the airport site.

Description Of Environment

• Study area covers the district of Thane and Panvel.

• Climate is hot and humid.

• it is included in Deccan Trap where all the balastic

compositions are surrounded by large no. Of dykes.

• Taloja river and Kasadi river in the North, Kalundri and Gadhi

river in the East and Ulwe river in the South.

• The physico-chemical parameters ranges value within the

prescribed standard except the BOD and nutrients.

• A total of 58 species of birds, 46 animals, 23 aquatic animals

and maximum of 198 plant were found in study area.

• There is no forest area in the project area.

7/28/2014 8

Description Of Environment• 50% of project area is open land, salt marshes cover another 25%,

10% under mangrove forest, rain fed agriculture occupies 7% area

rest is man-made things in the project area.

• Open land:

– hilly terrain extending NW and is towards the SW end of the proposed runway.

• Salt marshes:

– more common in the Eastern region of the site of proposed airport than in the

west.

– Used for Prawn culture and are also man made.

– No life as anaerobic condition prevails.

• Mangroves:

– Avicennia marina more dominant species found here.

• Agricultural Land:

– rain fed agriculture in mansoon else barren land.

– Brick making also observed.

Description Of Environment

• area includes places of

historical importance

such as:

– The Elephanta Caves.

– Karnala Bird

Sanctuary.

– Matheran Eco-

sensitive Zone.

7/28/2014 11

Project Activites

• Project area is about

2054 Ha.

• Airport zone is about

1615 Ha. Consisting of

1200 Ha. For

aeronautical activity and

415 Ha. For non-

aeronautical activity.

• Remaining area is there

for utility services.

7/28/2014 12

Positive Impacts

• Project will facilitate the fast movement of man and materials, thereby

fostering trade and commerce.

• support employment generation, CM outlined that around 1lakh direct jobs

and around 4lakh indirect jobs due to this project.

• Pressure on other airport at Santacruz will be eased.

• offer increased accessibility, which in turn fuels the tourism sector which

causes more money flows into the local economy.

• raising the standard of living of the people in the region. provides a thrust

to the GDP of the local region, having a positively impact on the national

economy.

• it will handle 60 million passengers/year which is much smaller than the

international standard of 100 million passengers/year so there is always

possibilities of expansion.

7/28/2014 13

Impacts due to NMIA Location• Removal of Mangroves & Biodiversity:

– With the project intervention, A total of 161.50 ha of mangroves (though in

degraded form) will be lost due to the project.

• Tree clearance:

– There is no forest in the project site area, though there are naturally growing

trees/plants/vegetation in the area.

– This project will result in loss of all vegetation in the project site.

• Roads and infrastruture:

– two impacts namely the over concretization and

– diversion of agricultural land leading to issues of land use change and food

security.

– Though the surface soil is being stripped off for brick making.

• Water ways connectivity:

– stress on the surrounding marine ecosystem and fishing.

• Rehabilitation:

– Ten settlements approx 15000 people will be affected due to the project.

7/28/2014 14

Impacts due to NMIA Project

Design• Training of Gadhi River:

– The impacts of channelization on the aquatic

community mainly arise due to clearing and

removal of vegetation.

– Siltation affects aquatic vegetation by

increasing the turbidity of water.

– loss and reduction in the number of organisms.

• Diversion of Ulwe River:

7/28/2014 15

Impact Due To Construction

Phase• Employment, Migration and Settlement:

– stress in the area surrounding the project in terms of water requirement,

power, increased ecological footprint, increased requirement for health

and educational facilities and changes in the land use pattern and local

culture.

• Siting of construction camp for construction:

– stress on the local ecological resources

• Leveling of site:

– leveling process would lead to an intense / heavy quantity of dust

which would raises the SPM levels in the vicinity.

– the noise levels would be high due to the machinery used for leveling.

• Safety of Workers

• Construction Activity

7/28/2014 16

Impacts during Operation Phase

of NMIA• Operation of airport:

– two major impacts

include that of air

emissions and noise.

• Surface Traffic:

– air quality is affected

– Noise also is affected

• Employment,

Migration &

Settlement:

7/28/2014 17

MITIGATION MEASURES

7/28/2014 18

Air sector• Appropriate dust suppression measures will

be implemented within the project site.

• Background air quality of all transport

corridors will be maintained by reducing

idling time and control on emissions.

• Aerobridges would be used for passenger

transportation

7/28/2014 19

Biodiversity and Forests• CIDCO has planned to take up approx 350 Ha. of

plantation of mangroves against the 161.50 Ha. Loss.

• The channelization activities are designed to keep flow

characteristics as close to the original natural flow.

• compensatory vegetation and plantation programme will

be undertaken within the airport area

• contamination of estuarine body would occur mostly

during the construction phase due to resuspension of

sediments or dust from construction site, both of which

are temporary.

• There was no wildlife, observed during the field survey.

Disaster management plan

• Natural Disasters:

– earthquake

– flood

– storms/cyclone

– cloud burst/lightning/extreme

weather conditions

– Fire

• Terror Attack, Plane Hijack,

Sabotage

• A highly equiped airport is

developed to counter all the

calamities and disasters.

• Aircraft Accident Related

Disasters:

– aircraft accident at airport

– aircraft accident off airport

– Hazardous material emergency,

hydrocarbon spills (ATF)

followed by vapour dispersion

and pool fire

– fire

Conclusion• The project is necessary and

should be given a nod.

• Development is necessary, but

development along with

environment is acceptable.

• So adopt sustainable

development.

• Human imagination is

touching sky, sky is part of

environment so better

preserve for imagination

hence future.

• Go green.
