- How many lakes in India?
- Dams: 5,100,
- f which 400 under
construction
- What data on lakes?
SLIDE 19
- Who administers lakes?
- MoEF.
- It gave Rs 1,000 to 100+ lakes
- For ‘development’ or ‘conservation’
- How many ‘conserved’?
- Examples of lakes:
- Hyderabad – use of JICA funds
- Bhopal – MoEF funds
- Ajmer – MoEF funds
- Pushkar – MoEF funds
- Udaipur – MoEF funds
SLIDE 20
Reasons for poor performance?
- (i) Lake development treated as an engineering design
- (ii) Lake not treated as the Natural Resource
- (iii) Restoration/conservation not accorded priority
- (iv) Ad hoc works initiated
- (v) Lack of monitoring
- (vi) Stake holders not involved
- (vii) Sewerage-treatment not addressed
- (viii) Eco System Based Approach not adopted
- (ix) Recycle and reuse of sewerage water not prioritized
- (x) MoEF reduced to a grant-agency
SLIDE 21
Possibilities:
(i) Lakes to offer quality water for uses (ii) Potable water use be separated (iii) Cities adopt own Water Budget (iv) Cities try to be self-sufficient in water
SLIDE 22
An Ideal model:
(i) Adopt re-cycle and re-use pattern (ii) Stop Chemical treatment at ETPs/STPs (iii) Start Bio Treatment (iv) Will reduce huge capital cost (v) Will avoid use of power (vi) Will reduce implementation time (v) No foul odour around
SLIDE 23
Inputs needed:
(i) Aquatic vegetation (ii) Fish, frogs, micro-organisms, etc (iii) Flow of water (flushing) (iv) Sedimentation Basin mechanism
SLIDE 24
An example: Jaipur’s Man Sagar:
(i) Drain bypassed (ii) Aquatic vegetation introduced (iii) Islands created (iv) Bio treatment of sewerage (v) Water depth increased (vi) Water did not dry up (vii) Foul odour gone (viii) Biodiversity revived (ix) Immense recreation (xi) Peoples’ life improving
SLIDE 25
PPP approach:
(i) Land around be lure (ii) Lake be objective (iii) Conservation-cap (iv) Model for other lakes
Possible :
- Yes. Jaipur has done it:
Citizens’ Birding Fairs (1997 continue)
- Govt. (2002) and
PPP (2005 onwards)

Hyderabad Recovery Scenario
SLIDE 27
Dal, richer with vegetation
SLIDE 28
Birds make Udaipur’s Pichhola rich
SLIDE 29
Chandalai on death bed
SLIDE 30
Jaipur’s Man Sagar: then (prior to 2005) and now (after 2006)
SLIDE 31
Inputs need recognition for Lakes
SLIDE 32
Inputs undermined at Lakes
SLIDE 33
An ideal can be recreated
