The Information Technology sector has a special significance for India, because India competence in this sector has made it a net exporter of IT services. It was the fastest growing sector of the nineties and continues to fast-track careers, spending power, local economies and real estate growth even today. The IT industry has three major components:

• The IT software and services industry
• The IT hardware, peripherals and networking industry
• The IT enabled services industry

The software sector has already established itself as a fast-growing sector. ITES includes services such as call centers, transcription, data processing, online education, etc. It has made a huge impact on international workflow into India, mainly because of low communication costs and the financial sense behind outsourcing non-core activities. It is an obvious advantage for any modern city to have a significant presence of this industry, which is creates white-collar, high-profile jobs and has remarkable effects on its real estate market.

Karnataka's thriving IT industry is mostly concentrated in and around Bangalore. The Information Technology in Karnataka state has become one of the main pillars of economy. Majority of IT activity in Karnataka is concentrated in Bangalore. Lately, other parts of Karnataka have also seen a growth in IT related activity. Some recent developments regarding the industry in Karnataka are described below.

Bangalore, has been recognized as a world renowned IT hub and considered as Silicon Valley of India/ the IT Capital of India. It is among the top 10 preferred entrepreneurial locations in the world. Many companies preferred Bangalore to start business operations. Many MNC's like HP, IBM, Intel, AMD, Cisco, Kyocera, Oracle etc. This has made Bangalore a first choice for IT investments

It has advantages like abundantly available skilled workforce, a high quality of living and inherent brand value, better career-growth prospects, availability of good telecommunication infrastructure and proactive Government policy initiatives. At the same time, other factors like the cost of real estate and ready access to international destinations also matter

The growth of IT has presented the city with unique challenges. Ideological clashes sometimes occur between the city's IT moguls, who demand an improvement in the city's infrastructure, and the state government, whose electoral base is primarily the people in rural Karnataka. The encouragement of high-tech industry in Bangalore, for example, has not favored local employment development, but has, instead, increased land values and forced out small enterprise. The state has also resisted the massive investments required to reverse the rapid decline in intra-city transport which has already begun to drive new and expanding businesses to other centers across India. Bengaluru is a hub for biotechnology related industry in India and in the year 2005, around 47% of the 265 biotechnology companies in India were located here; including Biocon, India's largest biotechnology company.

Because of these unique features, Bangalore has become a popular destination for immigrants from all over India However, a number of challenges pose threats to sustainable development of Bangalore including environmental degradation, high poverty level, overuse of underground Water, lack of fresh water and electricity, and poor infrastructure and recreational facilities, increase in living cost, temporary immigration.

This project seeks to explain how a complex and dynamic systems model can be developed and used as framework for decision making and capacity development for local government and private stakeholders/companies who share the responsibility of sustaining the system.

1. INTRODUCTION
In ancient times, the development of cities was synonymous with the development of civilizations. Cities emerged as a focal point of transport, trade, business, education, religion and governance. On these accounts rivers served as basic infrastructure in the form of inland transport, drinking water, irrigation and drainage potential. But the provision of services depends on the availability of sufficient infrastructure. Good infrastructure significantly improves the business environment and also contributes to the enhancement of the overall quality of life. In fact, quality of life is often dependent not only on the physical systems that sustain a community like water, roads, power, sewers, flood control, communication and waste management but also on public facilities and services like police, fire protection, parks, schools, libraries, health and social services. These services form the backbone of a growing community and play a major role in creating conditions for working.

2. Problem Structuring
This Project has been undertaken to highlight the disparity between the need and availability of basic facilities leading to tremendous pressure on physical and social infrastructure preventing the city of Bangalore from becoming the most formidable location for supporting the IT industry. In this stage, we will focus on the identifying the key issues, potential as well as challenges for sustainable development of Bangalore.
The first phase will be identifying the key issues and making a causal loop diagram as per system thinking approach.
The second phase will of simulating the problems using a dynamic system model using Vensim and coming to a conclusion from the findings.

3. IDENTIFYING THE KEY ISSUES
Provision of adequate infrastructure is essential in ensuring smooth functioning of the IT parks. Proper physical and social infrastructure along with the specifically needed IT infrastructure facilities have to be provided.
3.1 Physical Infrastructure Issues
Traffic and Transportation: Traffic congestion is perhaps the most severe in Bangalore. Transformation of the Garden city into the hi-tech city has resulted in an enormous increase in the number of vehicles on its small roads. The steep increase in these transport vehicles can be attributed to the increase in income levels, the preferences of the 20-30 age group, the absence of an adequate public transport system and also the innovative schemes offered by financial institutions. There is severe congestion created in the peak hours due to increased urbanization and ad-hoc developments on either side of the road. Since there are no well planned roads, congestion at the main entrance of the electronic city during peak hours is severe. The original road design does not cater to the drains, footpaths and service reserves adequately.

International Airport: Bangalore International Airport is located at Devanahalli, which is 40 km away from the city. All facilities are provided meeting International Air Transport Association standards. It will take at least three hours to reach BIA by road from Electronic City and Whitefield, where most of the IT companies are located. The onus now shifts to the state government, which has to provide better infrastructure to reach the airport. The government has to undertake several road works between Whitefield and Electronic City to the new airport in order to reduce travel time. A high speed railway track between the city and the airport is needed urgently.

Water Supply: The Bangalore Water Supply and Sewerage Board (BWSSB) is responsible for the provision of water to the city and its suburbs. As the present water demand is 1,219 MLD, there is a shortfall of 349 MLD (41 percent).

Power Supply: The Karnataka Power Transmission Corporation Limited is responsible for power transmission in the state. In 1906, Bangalore was the first city in India to have electricity. Regular, reliable, uninterrupted power is a great necessity for running IT software and services businesses. The power load growth of Bangalore District itself was 15–16 percent. In ITPB, the Infrastructure includes a dedicated power plant generating 12.5 MW and another 5 diesel generators for emergency ensures a third level of redundancy. With the increase in population the demand of power will keep on increasing and we need to see how to balance the use of power and power generation. Using nonrenewable sources of energy will add to the woes of govt. and people and will increase the cost of petrol and diesel which again add up to the price rise of resources we are facing presently.

Sewerage and Drainage: It is provided for the disposal of human waste within a controlled environment to protect the health of the communities. Approximately 70 percent of the population uses a drainage system that is open or covered, leading to natural outlets that are transformed into open-air sewage areas, in the heart of the city. The existing drainage system is inefficient, as it is undersized and clogged with garbage and silt.

Solid Waste Management: The production of solid waste is approximately 2,500 tons per day with 0.4 kg of waste produced per day per person in the city of Bangalore. Even though their collection is ensured fairly satisfactorily, their treatment poses a problem. Around 350 to 400 tons of waste is currently treated every day for composting, a procedure that is well adapted to the quality of waste in the city. The remaining solid wastes are deposited every day in the open and non-controlled zones, along the major arterial roads in the old quarries, and also in the valleys and near the lakes, which give rise to problems of pollution and risks of adversely affecting underground water resources.

3.2 Social Infrastructure Issues
Crime and Policing : Increased income difference between IT and Non It workers and the increase in prices of the basic commodities has increased the crime rate in city. Proper infrastructure has to be in place for the safety of people. Also as IT people work in three shifts, women are vulnerable during nights.

Fire Safety: Fire safety is an extremely critical component of the urban infrastructure as urban assets are generally highly susceptible to fires and disasters leading to huge losses in terms of money and lives. The Karnataka Fire Services Department is responsible for ensuring fire safety. There are only eleven fire stations in Bangalore Urban District against the recommended 140 by central government norms.

Education: Bangalore is traditionally a known centre for education and research. It is seeing a huge thrust in school education. Bangalore offers a peaceful environment, good climate and creative skill development. The significant increase in engineering colleges and the number of IT and related courses introduced in the state has also added to the infrastructure needs of Bangalore.

Healthcare: Most of the big hospitals have eminent doctors from abroad as consultants. Also, most hospitals that have foreign patients have facilities and services customized for the comfort and convenience of the patients (Breeze, 2008). Which also adds to price and the infrastructure needs of Bangalore and makes the specialized treatment away from common man (in context of private hospitals).

Leisure and Entertainment: Bangalore is known for its gardens and parks, natural lakes, architectural landmarks, shopping malls, the best restaurants and pubs. But with the rising population the need of the facilities is going higher have given rise to private leisure and entertainment club houses and sports facilities which are costly for common man.

Housing: There is a boom in the housing sector. The major reason for this is the easy availability of finance and also the income tax incentives for people taking a housing loan. So, most of the projects are for the upper class, the middle class that have guaranteed incomes. In Bangalore, independent houses have reduced because of high land values and also due to non-availability of land. This huge demand for houses has again helped in the mushrooming of apartments and rise of prices made the houses away from the reach of common man. Also due to large no of apartments the infrastructure need has again risen.

Because of IT companies the revenue has rapidly increased and become the largest contributor to the local and country economy. However, Bangalore is facing a number of severe and urgent environmental problems. These include environmental pollution, high levels of poverty in several communes, overuse of underground water, lack of fresh water and electricity (especially in the summer), high living cost, as well as poor infrastructure and recreational facilities. These problems pose serious threats to sustainable development of Bangalore.
