Strategic Action Planning for Revival of Bangalore Lakes outlines challenges facing the city's lakes. Rapid urbanization led to increased land and infrastructure needs, resulting in loss of forest cover. Untreated sewage, waste and industrial runoff pollute lakes. Encroachments changed land use and interrupted connecting channels. A coordinated, long-term strategic plan is needed to address issues from a watershed perspective using modern tools. Community involvement and innovative financing models are crucial for conservation.

7. 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)

8. 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

 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
