Bangalore Lakes: Progression of Issues
Encroachments
Change in Landuse
Interconnecting channels
Poor maintenanc
e
Interception and
impairment
Increased Pollution
Disposal of SW
Disposal of untreated Sewage
Industrial
Effluents
Immersion of Idols
Non-point
sources
Recreation and
other in-situ uses
Rapid Urbanization
Increased requirements of land, water & Infrastructure
Increased Waste, Runoff
Loss of forest cover
Decrease in Env. flows
Silting
Deterioration of Lakes
Pressure on Groundwater
Impacts on Lakes

Drying of lakes
GW Depletion and
Degradation
Change in Lake
morphology
Decrease in Env. flows
Decreased water
availability Decreased Biodiversity
Risks to Water Security
Effect on Micro-climate
Impact on Avian Fauna
Impacts: Short term? Long term? Reversible? Irreversible?
Risks to Water Security, Additionally of Climate Change?

Justice Patil Committee: Action Plan Allocation of Lakes to BBMP, BDA, LDA, KFD for –
Installation of fence and laying of embankments Identification of unauthorized construction within the
areas of the lakes and the removal thereof Removal of silt and weeds Stoppage of flow of untreated wastewater into lakes
Additional activities Survey of the lakes (Revenue Dept.) Water Quality monitoring (KSPCB) Management of sewage in the entire BBMP area
(BWSSB) Management of storm water (BBMP) Aforestation (Forests department)

What is needed? A strategic, coordinated and sustained scientific approach
is necessary Basin/ Watershed approach is required with lake
prioritization Lake degradation related issues need to be studied in depth Use of modern tools: Math modeling, Remote sensing, Bio-
monitoring Innovative technologies for in-situ treatment in channels, in-
situ remediation in lakes need to be explored New models for “conservation finance”, institutional roles
and partnerships

Strategic Action Plan …. Common Vision, Guiding and Operational
Principles Setting of Key Performance Indicators (KPIs) Developing a Strategic Action Plan Supported by policies and plans, enforcement,
roll out of programs & projects (investments), capacity building, monitoring & assessment, reporting
Addressing the lake eco-system as a whole in the catchment area (surface & ground water; forests, fauna & land resources, health and livelihoods)
Water security addressing threats due to climate change
