Lake Restoration, Issues & Application – the Case Of LAKE RESTORATION, ISSUES & APPLICATION – THE CASE OF BANGALORE Rajshekhar Rao Asst. professor M.S. Ramaiah Institute of Technology Bangalore INTRODUCTION Associated Values of Lakes and their importance Lakes are the lungs of natural ecosystems and perform several functions. Urban Lakes are however, only a subset of all fresh water bodies, i.e., Reservoirs, Lakes, Ponds, Tanks; etc. The lakes have inherent quality of storing and maintainingggp it for a much larger period than other wetlands. In recent years, there has been increasing concern over the continuing degradation of world's wetlands, particularly rivers and lakes. Lakes sustain all life and perform useful functions in the maintenance of ecological balance. Interfacing between land and water systems, they are highly productive and biologically rich ecosystems, and are also the most endangered. It is part of India’s national policy to conserve the existing lakes and plan and devise Environment Management plans. Efforts to conserve these fragile areas and develop them to promote eco -tourism should be undertaken to make aware and sensitive towards environment and protection of our natural resources. Study area - Bangalore Wetlands of Bangalore occupy about 4.8% of the geographical area (640 sq k)km) cover ing both urban and non-urban areas. Baagaoeasngalore has many man- Figure 1: Study Area –Greater Bangaloremade wetlands In Bangalore the lakes were built for various hydrological purposes and mainly to serve the needs of irrigate agriculture. There were 262 lakes (in 1960) within the Green be lt area of the city, which has fallen to 81 at present . Figure 2: Map showing lakes in Bangalore Lakes in Bangalore are threatened due to Industrialization Urbanization and unplanned growth Criteria for Selection of Bellandur Lake Bellandur Lake is the largest in Bangalore city, being 3km in length and 2.75km in Width. It is one of the largest man-made lakes in Southeast Asia, located about 20 km from the city tdthSthtowards the South-EtfBEast of Bangal ore c ithihitity which is extreme ly important ecological zone. Bellandur lake Historically, Bellandur Lake used to irrigation to the downstream 25,000 acres of agricultural fields. BlldBellandur LkLake functioned as the kidney of the city. The lake was home to a wide variety of fauna and attracted many migratory birds . The la ke a lso prov ide d drinking water to half the cityypp's population. In the past lake was a major fish trading Present Condition of Bellandur lake 3km in length and 2 .75km inWidth overall catchments area is 110.94 sq.miles The water storing capacity of Bellandur lake is 17. 66 m illion cu bic fee t. Lake polluted due to • Discharggge of sewage and other wastewater • Dumping of solid wastes into the storm water drains pollute the lake. • The lake contains raw sewage, • Industrial effluents and Domestic garbage. • Does not have proper sewerage System. Methodology : primary, secondary and public opinion surveys personal observations site visits and visual surveys were conducted in order to get data related to various aspects and understand the existing conditions. Studies were basically done at two levels- the Catchments Level and the lake Level- to identify the impacts of different natural and human activities on the lake eco-system. Aspects at the Catchments levels are. physiograpy, climate, land use, drainage, demography, socio-economic status, transportation network, infrastructure, and location of industries. Aspects at the lake level are biodiversity, water quality, land use, settlement pattern, socio-economic status, activities in lake, facilities and amenities, and commercial activities. In addition to this, tourism related data has also been analyzed to understand the eco- tourism prospects Figure 3: Existing land use map of Bellandur lake region Major problems and issues confronting Bellandur lake region: The threats to the BlldBellandur lklake reg ion Eco-system are ppyartly due to biotic pressure from the environment and mainly due to human induced or natural changes in the zone ofif in fluence.

Proposals are given for environmental quality improvement by restoration, relocation and rehabilitation of certain activities. Provision of adequate green areas, recreational areas and open areas ensure that environmentally sustainable tourism is established. Lastly, various strategies and guide lines and policies have been formulated for environmentally relevant sectors such as Industries, transportation, waste treatment, and tourism. Analysis: The analysis is done to understand the various environmental, social and economic problems on the basis of several criteria such as severity, extent and importance. Also the positive and negative impacts of all the different activities undertaken in the lklake are ana lyze d The Land use in the catchment is critically ittThdlimportant. The developmen t activities in the catchment area like veggggetation cutting, housing, development activities, construction of road etc, which increase the erosion rate. Any man made factors affect directly or indirectly affect the quantity and qualit y o f la ke water. So it is essential to stop any such activities in the lake The Land use around bellandur la To maintain the existing water quality the iden tifica tion of hydrological sensitive area are important.so hydrological analysis is carried out. It is observed that the water quality has been reddduced reaching the bellandur lake basin due to various development activity in the catchment Figure 5: hydrologically sensitive area of Bellandur lake catchment area of the lake. Eco sensitive Zones of Bellandur lake Catchment : The lake catchment has been assessed for the three basic resources which are land i.e. slope, Vegetation, and Hydrology. These factors have assigned value depending upon their criticality, by the superimposition of these parameters; it’s able to demarcate zones within the catchment as ecologically sensitive zones. The entire catchment has been subdivided in to four ecologically sensitive zones and the treatment of each zone hence varies accordingly. Figure 6: Map showing Ecosensitive zones of Bellandur Lake at Catchments Zone 1 : The outer zone is the Buffer zone of undisturbed vegetation buffered with trees & thick shrubs. Zone 2 : Agriculture zone, where farmers have been and would continue growing crops based on appropriate and sustainable farming principles. Zone 3 : Interface zone, the limits of which zone are determined based on the existence of marshes, ponds and etc on the simple rule that restricts farming on areas adjacent to water courses up to a width equal to at least the width of the stream.

  • The Role of Policies of Lake Water Management in Bangalore, India Lavanya Vikram 1, Neelima Reddy 2 1,2 MSRIT, Bangalore, Karnataka
    The role of Policies of Lake Water Management in Bangalore, India Lavanya Vikram 1, Neelima Reddy 2 1,2 MSRIT, Bangalore, Karnataka Abstract: Water pollution is a serious problem in India as its surface water resource and a growing percentage of its groundwater reserves are contaminated by pollutants. The high incidence of severe contamination near urban areas indicates that the industrial and domestic sectors contributing to water pollution is much higher. Water as an environmental resource is regenerative in the sense, that it could absorb pollution loads up to certain levels without affecting its quality. In fact there could be a problem of water pollution only if the pollution loads exceed the natural regenerative capacity of a water resource. The control of water pollution is therefore to reduce the pollution loads from anthropogenic activities to the natural regenerative capacity of the resource. The benefits of preservation of water quality are manifold. Agricultural run-offs affect groundwater and surface water sources as they contain pesticide and fertilizer residues. Fertilizers have an indirect adverse impact on water resources. Indeed, by increasing the nutritional content of water courses, fertilizers allow organisms to proliferate. Storm water runoff from urban areas is a major source for contamination of water. It should be clearly understood that the role of policies to be compensated fully for the damages from any kind of pollution. Using available data and case studies, this paper aims to provide an overview of the extent, impacts, and control of water pollution in India, taking the case of lakes in Bangalore. Keywords: water pollution, environmental issues, lakes, land use, guidelines 1.

Vinod Kumar and Sheriff Vaseem Anjum Department of Architecture, BMSCE, Autonomous under VTU, Bangalore - 560 019, Karnataka, India; [email protected], [email protected], [email protected], [email protected], [email protected], [email protected] Abstract Bangalore, when founded by Kempegowda I, faced water scarcity, which was mitigated by the ruler by building reservoirs as tanks and lakes. With rapid urbanisation, the lakes have been encroached upon and have given way to build struc- tures catering to the citizen’s needs. According to study conducted by the Energy and Wetland Research Group, Centre for Ecological Sciences, Indian Institute of Science, the 262 wetlands that existed in Bangalore in 1962 has declined by 58% by 2007. Similarly, when the city’s built up area shot up by 466% between 1973 and 2007, the number of lakes came down from 159 to 93. Lakes also sustained over the years due to the active linkages between them, which are now part of the hardscape of the city. With the increase in built environment, the city is losing out on softscapes that help rejuvenate the water table through percolation. The storm water drains established by the erstwhile rulers of Bangalore are turning grey. One of the lakes in Bangalore which is rapidly losing out on its ability to cater to the biodiversity and turning grey is Ulsoor Lake.

Each and every human activities supports directly/indirectly by natural factors. India is facing a problem of natural resource scarcity, especially of water in view of population growth and economic development. Due to growth of Population, advancement in agriculture, urbanization and industrialization has made surface water pollution a great problem and decreased the availability of drinking water. Many parts of the world face such a scarcity of water. Lakes are important feature of the Earth’s landscape which are not only the source of precious water, but provide valuable habitats to plants and animals, moderate hydrological cycles, influence microclimate, enhance the aesthetic beauty of the landscape and extend many recreational opportunities to humankind .For issues, perspectives on pollution, restoration and management of Bellandur Lake Falls under Bangalore Metropolitan city is very essential to know their status but so far, there was no systematic environmental study carried out.

However, on-going lake restorations often focus on recreation while excluding other users such as the urban poor, and fail to take into account lake connectivity and ecological function. Furthermore, restoration events are not followed up with adequate management actions. This study analyses and contrasts five lakes with co-management agreements, of which two were in more advanced state, and present the findings based on interviews with individuals involved in the initiatives. Aim was to a) identify key phases in navigating change, and b) actors who were key in the different phases and their characteristics.

BOX 11000, 00076 AALTO www.aalto.fi Master of Arts thesis abstract Abstract This master’s thesis investigates how design interventions can enable public participation in the functioning of a sustainable urban water management system, specifically by increasing awareness of the system by involving members of the communities that are linked to it. A unique closed-loop urban water management system — the Jakkur Lake in Bangalore (India) — is utilised as a case study to do so. The Jakkur Lake is one of the largest and cleanest water bodies in Bangalore and is particularly special because it is a potential model for Integrated Urban Water Management (IUWM). This complex socio-ecological ecosystem highlights the symbiotic relationship between nature and hu- mankind. By serendipity, a sewage treatment plant (STP) with a capacity to treat 10 million litres a day was set up north of the lake by the government bodies. The plant currently releases 8 million litres of treated water into the man-made wetland which further purifies the water by a natural process before letting it enter the lake. Therefore the lake is fed with this treated water everyday, which in turn recharges the ground, increases the water table and fills up the bore-wells and the beautiful old open wells — heritage structures that adorn this area and are in need of preserva- tion.

  • Bacterial Community Analysis of Seven Polluted Lakes In
    BACTERIAL COMMUNITY ANALYSIS OF SEVEN POLLUTED LAKES IN BANGALORE, INDIA: THE FOAM STOPS HERE AN HONORS THESIS SUBMITTED ON THE FIFTH DAY OF MAY, 2020 TO THE DEPARTMENT OF PUBLIC HEALTH IN PARTIAL FULFILLMENT OF THE REQUIREMENTS OF THE HONORS PROGRAM OF NEWCOMB-TULANE COLLEGE TULANE UNIVERSITY FOR THE DEGREE OF BACHELOR OF SCIENCE IN PUBLIC HEALTH WITH HONORS IN PUBLIC HEALTH BY _________________________________ Tanya Sarah Isaac APPROVED: Dr. Samendra Sherchan Director of Thesis Dr. Mark Wilson Second Reader Dr. Laurie O’Brien Third Reader Abstract This study analyzes the microbial population of seven highly polluted lakes in the Varthur lake series in Bangalore, Karnataka. Unchecked development made Bangalore the center of India’s IT development, which led to a demographic transition. This resulted in a city populated with thirteen million people whose sewage needs could not be met. Due to increased industrial pollution and poor sewage disposal practices, approximately 60% of Bangalore’s sewage goes into the Varthur lake series, primarily into Varthur and Bellandur lakes causing the proliferation of pathogenic bacteria and opportunistic pathogens. Water samples were collected in December 2019 from seven lakes in the Varthur lake series to determine the level of opportunistic pathogens in these water bodies. Nanopore sequencing of 16S rRNA genes identified several pathogenic bacterial strains such as Escherichia coli, Klebsiella pneumoniae, and mycobacterium and industrially important species such as Pseudomonas aeruginosa. The dominant microorganisms found in the Varthur lake series belonged to the phyla Proteobacteria, Bacteroidetes, Firmicutes, and Cyanobacteria. Additionally, all seven samples had fecal indicator organisms indicating fecal contamination. The results of this study indicate the need for drastic and immediate control and remediation measures to reduce neighboring communities’ exposure to these harmful pathogens.

  • Tracing the Impact of Bangalore's Urbanisation
    International Journal of Environment, Ecology, Family and Urban Studies (IJEEFUS) ISSN 2250-0065 Vol.2, Issue 4 Dec 2012 23- 28 © TJPRC Pvt. Ltd., TRACING THE IMPACT OF BANGALORE’S URBANISATION ON ITS WETLANDS WITH A CASE STUDY OF SAMPANGI LAKE 1FATHIMA SAMANA S & 2RAJESH GOPINATH 1 Assistant Professor, Acharya’s NRV School of Architetcure, Bangalore, India 2 Assistant Professor, Department of Civil Engineering, AIT, Bangalore, India ABSTRACT Urbanisation is an inevitable phenomenon introducing drastic transitions in the natural landscape. As the demography is altered, it directly and indirectly impairs the city’s natural resources inclusive of the water-bodies. The present research envisages the makeover of Bangalore and its wetlands due to inadvertent urbanisation. In 1537, when the city was founded, significant prominence was given to water-bodies during the planning process. However, the city currently strikes a sorry note, as its evolution into a metropolitan has triggered rampant new land-uses. This revolution, triggered by various government initiatives, privatisation and encroachments led to significant deterioration in the water- bodies, both quantitatively and qualitatively. The current study closely follows Bangalore’s urbanisation pattern from 1537AD and enlists the determinants that brought about the loss of its several wetlands. The research concludes with the analysis of the transformation pattern for Sampangi Lake with the aid of historical and current land-use maps, till its disappearance in the current scenario. KEYWORDS : Urbanisation, Determinants, Sampangi Lake, Quantitatively, Land-Use, Wetlands. INTRODUCTION Urbanisation brings about high rate of population growth in cities due to steep development in industrial, residential and commercial sectors. However, this also transcribes into decline of the natural resources.
