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
