TECHNICAL SESSION I: LAKE ECOSYSTEM

Chairman: Sri. A.C. Lakshmana IFS, Former Forest Secretary to Government of Karnataka.

Key speakers:

Prof. U N Ravi Kumar emphasised on overview of ecosystem, biosphere, various types of wetlands etc. The encroachment of water bodies is due to indiscriminate urban development, as in case of Bangalore- reasons include transportation, cultivation, sewage disposal and siltation etc. Ecological functions of terrestrial system are significant- wetlands is play a very important role in water bodies conservation, Eco-tones, wetland plants, biotechnology wetlands, construction of bio-deck using local materials.  CHINAMPAS –water based agriculture practice system is good example for management of wetlands and water bodies. The case example of Mysore includes the catchments of Karanji Lake, Bommanahalli lake.

Dr. Shankar P Hosmani  discussed on Phycology of lakes (study on Algae in lakes) and types of algae – Eugleanceae, chlorococcales, Bacillariophyceae, Desmids, Desmedium (Chain Desmid), Closterium, Spirulina species, Dinofagellates (form in Drinking water), Haematococcus pluvalis, Nodularia spumigena, Anatoxins etc. Also discussed was the possibility of using the diatom data to obtain and model using the software to result in  gives the ecological values of Ph, BOD level etc. The non desirable algae include arthrospira platensis and raphidiopsis medeteraina, filamentous algae are dangerous in the urban lake for examples Microcystis was found in Kukkarahalli Lake.

He had suggested some policy is required for reduce algae formation in water bodies and Nitrosamines culture spread to algae (adopted in Hussein Sagar Lake in Hyderabad)can reduce algae formation. The use of Phycotechnology- Earth bounding, algae utilisation is the need of the day. On another level, the algae structure and formation is source of inspiration to fashion designers for design and ornamentation.

Dr. M B Krishna spoke about wetlands for wildlife and the lake ecosystem as open house classroom for education. He emphasised on the wetland values for education, while seeking the recognition of the urban and sub-urban wetlands. Numerous examples of the Bangalore lakes were taken up.

Prof. K.B. Sadananda had discussed Flora of the water bodies – aquatic plants; aesthetical value of flora cannot be neglected in the discussion of the water bodies was emphasised.

Dr. S. Ravichandra Reddy had discussed on fauna of urban lakes and its Terrestrial zone, littoral zones and limonitic zones and fauna classification such as Periphyton – algae, Plankton, Benthos, Fishes, Amphibians, water snakes, turtle, Birds etc. Various instruments are available for assessing the sediment, etc.  EKMAN GRAB an instrument is used to know the bottom sediment sampler. He discussed the various species of fishes that are present in the different water bodies.

In discussions, the following points were highlighted.

  • Baseline information is important as the restoration can be centered on the environmental factors.
  • Common platform is required to address the issues of technical, social and physical aspects for sustainable management of water bodies.
  • Policy should be designed in such a way that water bodies’ ownership and management should be regulated by a single entity. The directions for restoration should be spelt out by the government sector, while it should yield some economic benefits. This can be inclusive addressing both the “have’s” and “have not’s”.

Sri. Munikrishan IPS has talk about reclaiming encroached urban lakes and catchment area and one of the important mile stones is GREEN BENCH was constituted in the Supreme Court. Human beings polluted the World beyond its recognition and tremendous advancement of science and technology increased our unhappiness and removed instinct happiness. And also discussed about feeder channels cannot be encroached or reduce the flow is punishable under IPC and wisdom can generate liberty.

Prof. Jagannath had pointed out Ecological Literacy Campaign were being organised from past five years and discussed about lakes conservation funded by ADB and ILEC (International Lake and Environment Committee) norms and standards and documentation of water bodies and should provide stakeholders space for management.


 

FILED VISIT

Key speakers:

Prof. T.V. Ramachandra -Changing role in urban wetlands

He emphasised on overview of the wetlands in Karnataka and wet land is about 3% of Indian landscape, wetlands mismanagement, spread of microphytes in water bodies, goods and services unpolluted and polluted. Policy should be focussed on conservation of future of wetlands, integration of catchment area to ensure lakes are perennial, physical integration, establish interconnectivity, remove of encroachment and stop introducing exotic species. Discussion about the urbanisation in Bangalore, urban sprawl, built up areas and phases of development, missing of lakes and the virtual conversion to various other urban uses, quantum of wastes dumped in undesignated places in Bangalore  was carried out in brief. Implications of loss of water bodies, loss of sensitive habitats, declining ground water table and changing climate etc was highlighted with use of the remote sensing data and detailed analysis. Information on the research findings are on the website of the IISc, CES.

Mr. Gopiprasad S, Director, IDES Consulting Pvt. Ltd. presented integrating water bodies in urban development. Tracing the path of water bodies in different phases, focus on integration was necessary by the deployment of planning and development.  Interconnected tanks, natural pattern verses urbanisation key conflicts, opportunities, offer possibilities for integration.

Mr. S Vishwanath, Rain Water Club, Bangalore presented the future role of tanks and manage aquifer, urban water management transition framework of cities, watersheds, sub-aquifers, hydrozonic connection between the chain of tanks, roof top rain water can be used for impoundment of water bodies and bio -diversity linking with housing level.

Discussions

  • Think of harvesting in storm water drains in Mysore the storm water flow from Hebbal to sewage form area of Vidyaranapuram
  • Integration of water bodies at ward level and community level

  • Inventory of water bodies and provide unique identity number
  • Issue notice under appropriate legislative framework for encroachment of lakes
  • Prepare lake TIPPANI Map and provide details of extent, boundary description etc.
  • Notify all the water bodies, valley zones, Raja Kaluves a ecological fragile zones
  • Special court for deal with lake matters

Sri. Kulkarni, spoke on the duties and responsibilities of the citizen for management of water and waste is major concerns today.

Discussions

  • No attention for water into tank for restoration projects
  • Rain water harvesting guidelines for catchment area at building level
  • Instead of transportation of desiltation can be utilised within the lake itself.
  • Karnataka Lake Protection Act
  • Provision for arresting Eutropication of lake by using nitrosamines
  • Community involvement for lake management to convergence at policy level or alternative institute at community level
