  • Could you let me know where you obtained the data for some of the great maps of Bangalore's urban growth? I'm specifically interested in the slide of "Metropolitan Expansion" and its data, as well as "Residential Projects under Construction." You do cite "Government Sources," I believe, but I'd love to download some of the data sources! thanks so much, Daniel Brownstein, Ph.D.

  4. 4. CLIMATE- • The climate of Bangalore is classified as the tropical wet and seasonally dry. • Dry season - December to February. • Summer season - March to May.. • South-West monsoon - June to September. • Temperature -mean maximum -33.4 ° C in April/May mean minimumof 15 ° C in December/January. • Relative humidity - mean monthly - 44% (min) in March - 85% (max) in October. • The mean annual rainfall is 889 mm. • Wind - easterly and westerly predominant directions. • May to September - WSW to W. • November to March -ENE to ESE. • Bangalore city is located in a seismically stable region (Zone II ).
  5. 5.  ORIGIN & EVOLUTION • In 1537 CE, Kempe Gowda — a feudatory ruler under the Vijayanagara Empire established a mud fort considered to be the foundation of modern Bangalore. • Within the fort, the town was divided into smaller divisions, each called a "pete“. • The town had two main streets—Chikkapete Street, which ran east-west, and Doddapete Street, which ran north-south. • Their intersection formed the Doddapeté Square—the heart of Bangalore. • Kempé Gowda's successor, Kempé Gowda II, built four towers that marked Bangalore's boundary. • Following by the Marathas and Mughals, the city remained under the Mysore kingdom. • Bangalore continued to be a cantonment of the British Raj.

  7. 7. • As a city, Bangalore’s history in the last six decades has undergone many changes. In the post independence decades Bangalore was known as a Garden City of retirees’ bunglows, and for a significant public sector presence, as a large number of centrally owned public sector units as well as state government owned enterprises were set up from the early to mid nineteen fifties onwards. The city also saw the growth of several premier scientific research institutions, set up by the central government. Garden City Of India
  8. 8. Garden City to Silicon Valley • As the era of economic reforms began, from the late 1980s, successive governments in Karnataka, across political parties, pushed an economic reform agenda due to which as is well known now, the city has now become the icon of India’s information technology revolution, a major centre for multi national companies, international banking, finance and hospitality, and an attractive destination for an upwardly mobile, tech savvy middle and upper class of citizens with multiple channels of connection to the global economy and culture. • All of this has entirely transformed the city’s landscape, as real estate prices soared in the wake of the economic boom, and the horizontal architecture of yesteryears gave way to the inevitable multi storied complexes of offices and residences, malls and multiplexes. • Bangalore is now known as the Silicon Valley of India because of the large number of information technology companies located in the city which contributed 33% of India's IT exports in 2006–07. • Bangalore's IT industry is divided into three main clusters — Software Technology Parks of India (STPI); International Tech Park, Bangalore (ITPB); and Electronics City.

  14. 14. ECONOMIC DEVELOPMENT - The growth of Bangalore from a town to a metropolis has been a result of five growth events: • Shifting the state capital from Mysore; • Establishment of Cantonment; • Setting up Public Sector Undertakings/Academic Institutions; • Development of Textile Industry; and • Development of Information Technology/ ITES/ Biotech based Industries. The distribution of economic activities in the city reflects its history, its different stages of development as well as the underlying socio-spatial contexts. Several distinct areas or spatial groups emerge from the geographical distribution of activities in Bangalore. These spatial groups are: • The “Old Petta”, the historical heart of the city, constitutes a very important centre of wholesale and retail activities. • The North-East- form a second commercial hub in the Cantonment area. • In the East, Chennai railway lime and Whitefield Road are important corridors that includes the International Technology Park Ltd. • South-East- Electronic city area with large Public and Private software and IT enterprises. • Western zone- Housing sector for most manufacturing workers • North-south axis- Households for those engaged in trade and business. • North- East- Households for those engaged in public and administrative services.

  21. 21. Proposed Land Use Map
  22. 22. BANGLORE Bangalore gets its water from the Cauvery river about 95km from the city. Bangalore Water Supply
  23. 23. Bangalore Water Supply • The supply was augmented in 1933 from Chamaraja Sagara Reservoir built across River Arkavathi . • The Cauvery Water Supply Scheme started in 1974. • 1st stage – 1974 - 135 MLD • 2nd stage- 1983 - 135 MLD • 3rd stage- 1993 - 270MLD • 4TH stage Phase I -2002 - 270 MLD • 4th stage Phase II-2012 - 500MLD • TOTAL : 1310 MLD • Bangalore Water Supply and Sewage Board(BWSSB) formed in 1964 now adequate water supply for the city.
  24. 24. Sources of Drinking Water
  25. 25. Present Water Supply Scenario • Present Population as on 2011 : 9.5 Million • Present Demand : 1283 MLD • Present Supply : 900 MLD • Water deficit : 383 MLD • The Per Capita Supply : 90 to 100 ltrs • No. of Connections (Consumers) : 6.47 Lakhs • Total Length of Water Supply Line : 5975 Km • Total Length of Sewer Line : 3712 Km • No. of Service Stations : 106 • No. of Reservoirs in the city : 52 • No. of Booster Pumping Stations : 62 • Pumping Capacity -------- Number : 247 • Capacity : 169240 Hp • Power charges per year : Rs. 305 Crores • Sanction Strength of Employees : 3500
  26. 26. Sewage • The number of households connected to the sewage network increased from 157,000 in 1991 to 344,000 in 2001, and the population grew from 18.9% to 30%. • The significance of this rate, which just concerns the connections to the formal well-to-do category of the population, indicates, the lack of sewage network on one hand and on the other, the fact that often covered storm water drains are used for sewage disposal. • The result is that about 70% ofthe BMP population uses a drainage system that translates to a geographical area of about 40% of the total LPA area.
  27. 27. Solid Waste Disposal • The production of Waste in Bangalore is approximately 2200 tons per day, with 0.4 kg of Waste produced per day per person. While collection is carried out regularly, Waste treatment is an issue of concern. • Only 300 to 350 tons of Waste is currently treated every day for composting and the remaining Waste is disposed in an unhygienic manner. • At present the City has treatment and disposal facilities with combined capacity of 2000 MT and 1600 MT, respectively. • New dump sites and landfill sites are to be identified and developed to serve the purpose.
  28. 28. Drainage • The growing geographic spread of Bangalore and accompanying construction activity has interrupted the natural valley system of the region. • Construction has also resulted in tilling up small Water bodies and low-lying areas. The flooding of drains during each monsoon exposes its poor state and their inadequate capacity, and impacts the City’s overall infrastructure. • With the growth of the City, the number of lakes has reduced to 64 from 400, and small lakes and tank beds have vanished because of encroachment and construction activities. • This has resulted in storm-Water drains reducing to gitters of insutlicient capacity, leading to flooding during monsoon. • Dumping of municipal solid Waste (MSW) in the drains compounds the problem and leads to blockages. • To control floods, it is important to remove silt and Widen these storm Water drains to maintain the chain flow and avoid Water from stagnating at one point.
  29. 29. Health infrastructure • Health infrastructure and facilities have improved and today Bangalore has high quality super speciality health institutions compared to other big cities. • The number of hospital beds for 1000 people have increased in ten years from 2.4 to 4.08 . • Access to different levels of health care (primary, secondary, tertiary) is generally satisfactory in spite of the shortage of amenities in the poorer areas such as Kenrpapura, Agralrara and Baiyyappanahalli. etc and the concentration of facilities in the city’s core area in relation to the peripheral areas. • Nearly three fourths of health services is provided by the private sector while the health services offered by parastatal agencies play an important role at the primary level and needs greater attention.
  30. 30. • Areas deficient in health and education in the city is depicted in Figure as Shadow Areas.
  31. 31. Education • Bangalore known for its high quality educational system and training institutions has about 80% literacy rate, which is high in comparison with the state average of 67%. • The numbers and reputation of universities, engineering colleges and other training institutions confirm, beyond the boundaries of the State. • At the city level. the existing norms (number of students per' institution) for higher primary schools (1.64) and for high schools (3.15) are higher than that of primary schools (1.04). • Primary level education faces unfavorable conditions as compared to secondary and pre-university level education. which benefit from more facilities. • With a ratio of one primary school for 2450 persons and 32 students per teacher for the primary level (compared to a generally accepted average of 40 students per' teacher), the situation seems quantitatively satisfactory. • However. the major problem is the ratio of public and private educational facilities. Private schools represent 75% of institutions and this is a concern for all the categories of the population. • Public institutions have limited resources and their objective is to eliminate illiteracy particularly among the poorer section.
  32. 32. • HOUSING :-
  34. 34. Slum Population :
  35. 35. Types of Slums :- 1. Notified Slums 2. Non Notified Slums
  36. 36. • Bangalore has a radio-concentric system structured by ring roads, five major radial roads and five secondary radial roads that converge towards the centre of the city. • The major and secondary radial roads that form a ten-pointed star constitute the organizational system of the city and are important as they support both industrial and commercial development.

  39. 39. Traffic Impression :
  40. 40. ENVIRONMENTAL IMPACT The environmental impacts of the problems associated with urban planning and growth are listed below: • ground water contamination due to soak pits and improper drainage system near open wells, • decrease in groundwater recharge due to increasing surface runoff due to paved areas, • polluting surface water bodies like tanks by the letting sewage into the lakes, • health problems due to uncollected garbage strewn around, • health problems due to crowding of families in one- room or two-room houses, • increase in temperatures due to radiation from buildings and paved roads (heat islands), and In adequate tree cover to counter this rise in temperature. Air circulation is also reduced due to the dense residential development and loss of vegetation/tree cover,
