Norms |
Location of the project (SEZ by Karnataka Industrial Areas Development Board (KIADB)) in the valley zone |
This is contrary to sustainable development as the natural resources (lake, wetlands) get affected due to this decision. Eventually this kills the lake. This reflects the ignorance of the administrative machinery on the importance of ecosystems and the need to protect valley zones |
The proposed activity is in valley zone |
To be protected considering ecological function
And are ‘NO DEVELOPMENT ZONES’ as per CDP 2005, 2015 |
Location of SEZ in flood prone zone of the lake and in wetland - 30 m buffer zone of the water body is to be no development zone |
In case of water bodies a 30.0 m buffer of ‘no development zone’ is to be maintained
around the lake (as per revenue records)
- As per BDA, RMP 2015
- section 17 of KTCP Act, 1961 and sec 32 of BDA Act, 1976
- Wetlands (Conservation and Management) rules 2010, Government of India

Alterations in topography |
Adjacent localities would be vulnerable to floods |
Removal of rajakaluve (storm water drain) and gradual encroachment of rajakaluve as well as lake bed |
Removal of lake connectivity enhances the episodes of flooding and associated disasters
The Hon’ble Supreme Court in Civil appeal number 1132/2011 at SLP (C) 3109/2011 on January 28,2011 has ex-pressed concern regarding encroachment of common property resources, more particularly lakes and it has directed the state governments for removal of encroachments on all community lands.
Eviction of encroachment: Need to be evicted as per Karnataka Public Premises (eviction of unauthorised occupants) 1974 and the Karnataka Land Revenue Act, 1964. |
The proposed action by KIADB to set up SEZ violates Hon’ble High Court of Karnataka’s verdict to protect, conserve, rehabilitate and wisely use lakes and their watersheds in Bangalore all lakes in Karnataka and their canal networks (about 38,000) |
High Court of Karnataka (WP No. 817/2008)
- Protects lakes across Karnataka,
- Prohibits dumping of Garbage and Sewage in Lakes
- Lake area to be surveyed and fenced and declare a no development zonearound lakes
- Encroachments to be removed.
- Forest department to plant trees in consultation with experts in lake surroundings and in the watershed region
- Member Secretary of state legal services authority to monitor implementation of the above incoordination with Revenue and Forest Departments.
- Also set up district lake protection committees

Additional 10000 to 14000 vehicles |
Increases traffic bottleneck in the region and air pollution (with the increase in density of vehicles) |
Increase in vehicular traffic and enhanced pollutants |
Traffic congestion (due to additional vehicle movement). The density of traffic would increase, the road’s current level of service (LOS) is under category C , the increase in vehicles upto 14000+ would worsen the traffic condition with LOS under category F. enhanced levels of vehicular pollutants; likely increase in respiratory diseases; |
Water shortage
The estimate shows that SEZ requires 4587 Kilo Liters per day (4.58 MLD – Million liters per day) |
Bangalore is already experiencing severe water shortages as water yield in rivers (Cauvery, etc.) has come down due to large scale land cover changes. Neither Cauvery, T G Halli nor groundwater can sustain Bangalore’s growing water demand.BWSSB has not given NOC and has indicated inability to supply such huge quantity of water on regular basis. |
Pathetic water scenario and insufficient drinking water in Bangalore |
At the 4% population growth rate of Bangalore over the past 50 years, the current population of Bangalore is 8.5 million (2011). Water supply from Hessarghatta has dried, Tippegondahanally is drying up, the only reliable water supply to Bangalore is from Cauvery with a gross of 1,410 million liters a day (MLD). There is no way of increasing the drawal from Cauvery as the allocation by the Cauvery Water Disputes Tribunal for the entire urban and rural population in Cauvery Basin in Karnataka is only 8.75 TMC ft (one thousand million cubic – TMC ft equals 78 MLD), Bangalore city is already drawing more water—1,400 MLD equals 18 TMC—than the allocation for the entire rural and urban population in Cauvery basin. |
Ecological and Environmental Implications:
- Land use change: Conversion of watershed area especially valley regions of the lake to paved surfaces would alter the hydrological regime.
- Loss of Drainage Network: Removal of drain (Rajakaluve) and reducing the width of the drain would flood the surrounding residential as the interconnectivities among lakes are lost and there are no mechanisms for the excessive storm water to drain and thus the water stagnates flooding in the surroundings.
- Alteration in landscape topography: This activity alters the integrity of the region affecting the lake catchment. This would also have serious implications on the storm water flow in the catchment.
The dumping of construction waste along the lakebed and lake has altered the natural topography thus rendering the storm water runoff to take a new course that might get into the existing residential areas. Such alteration of topography would not be geologically stable apart from causing soil erosion and lead to siltation in the lake.
- Loss of Shoreline: The loss of shoreline along the lakebed results in the habitat destruction for most of the shoreline birds that wade in this region. Some of the shoreline wading birds like the Stilts, Sandpipers; etc will be devoid of their habitat forcing them to move out such disturbed habitats. It was also apparent from the field investigations that with the illogical land filling and dumping taking place in the Bellandur lakebed, the shoreline are gobbled up by these activities.
- Loss of livelihood: Local people are dependent on the wetlands for fodder, fish etc. estimate shows that wetlands provide goods and services worth Rs 10500 per hectare per day (Ramachandra et al., 2005).
Decision makers need to learn from the similar historical blunder of plundering ecosystems as in the case of Black Swan event (http://blackswanevents.org/?page_id=26) of evacuating half of the city in 10 years due to water scarcity, contaminated water, etc. or abandoning of FatehpurSikhri and fading out of AdilShahi’sBijapur, or ecological disaster at Easter Island or Vijayanagara empire.
It is the responsibility of Bangalore citizens (for intergenerational equity, sustenance of natural resources and to prevent human-made disasters such as floods, etc.) to stall the irrational conversion of land in the name of development and restrict the decision makers taking the system (ecosystem including humans) for granted as in the case of Bellandur wetlands by KIADB. |
