  2. 2. About EMPRI  EMPRI is an autonomous body under the Department of Forest, Ecology & Environment, Government of Karnataka  With a vision to become a knowledge Centre inspiring and enabling society to create an environment of harmony between man and nature  To conduct research on environmental policy and current environmental issues  To provide world class training and advisory services on environmental management  To enable and encourage civil society, the government and the industries to safeguard and manage natural resources effectively Centre for Lake Conservation Environmental Management & Policy Research Institute
  3. 3. Why this Study?  Lack of comprehensive data on water bodies like Lakes, Gokattes & Kuntes  Water bodies are under severe threat due to rapid urbanisation/ industrialisation  Bangalore is already facing acute water scarcity and certainly increase by leaps and bounds  Finding possible ways for conserving these water bodies and to enhance their ecological and economical values Centre for Lake Conservation Environmental Management & Policy Research Institute

  7. 7. Coding of water bodies BS KG bmk 01 038 Taluk Name Bang. South Hobli Name Kengeri Village Name Bhimnakuppe Kere EMPRI Code No.BgU District Name Bang. Urban Eg. Bhimanakuppe Hosakere: BgUBSKGbmk_kr01-038 kr Waterbody No. in Village kugk KunteGokatte  One water body may have different names and most of them are called as Hosakere  MI Tank Reg. No. is based on districts (for eg. Magadi district is now Bangalore Urban and now No. are mention two lakes) not directly represent the location of waterbody (Village, Taluk, etc.)  Feeder tanks (Gokatte & Kunte) were not considered during Numbering  EMPRI has developed the unique ID codes for all the water bodies by following the ISO Standard
