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
