Bangalore is India’s third most populous city and is among the top 100 cities that contribute to the global economy. 75 percent of Bengaluru’s income is from the service sector, with over ₹ 500 billion (approximately US $7.6 billion) from IT and real estate. Several Fortune 500 companies have their offices in Bangalore. In 2014, the city received the ninth highest number of foreign investment projects in the world.
While this growth has increased incomes, it has also led to infrastructure problems, like poor quality of water, unreliable power and traffic congestion. Public investments in infrastructure have not kept pace with growth, giving rise to self-provisioning solutions like diesel-powered generators, bore-wells and packaged water that have created environmental and health concerns. Bangalore needs to sustain its economic growth and improve quality of life for its citizens to maintain its appeal for investors and talent. In its attempt to address congestion, limit sprawl and improve efficiency, Bangalore has to now make key decisions on land-use, infrastructure, transport and energy.
In the last 20-30 years, Bangalore has been building wider, faster roads and flyovers in response to the growing number of vehicles in the city. This approach has failed. Not only has it made it unsafe for pedestrians, but it has also resulted in the city having the sixth worst traffic jams in the world. With the metro still under construction, the city’s public bus operator, BMTC, carries the majority of the commuter load—42 percent. However, increasing costs and inefficient operations has resulted in a less than optimal quality of service. Every day, 5.2 million people commute via 6,700 buses operated by BMTC.
To actively address congestion and solve mobility and accessibility issues, Bangalore needs to (1) redesign roads to make them safer for all users, and specifically for pedestrians and cyclists, (2) improve speed and quality of bus-based mass transport, including bus rapid transit (BRT), in addition to Namma Metro, (3) integrate various modes of public transport and intermediate public transport through schedule, fare and physical integration, (4) develop progressive regulations for emerging shared mobility options like ridesharing, carpooling, shared bicycles and taxi aggregators and (5) ensure car-users pay the full cost driving, including the costs of parking and congestion.
Managing Urban Expansion
Bangalore has led the growth of India’s technology industries. These emerging economies are located in the suburbs and peripheries of the main city and have global access. While the core city is undergoing some transformation, the peripheries have seen rapid growth. From 2006 to 2012, the metropolitan region added 1228 square feet per minute. Over 10,000 gated residential developments now dot the region. Areas such as Whitefield and BIAAPA are manifestations of this growth. In order to manage expansion in a sustainable manner, Bangalore needs to:
- Move from a traditional static land-use approach for planning and development, and adopt a strategic spatial planning approach.
- Leverage the US $2 billion investment in Namma Metro by implementing transit-oriented development principles in its well-serviced core area.
- Develop peripheral and satellite ring roads as area-based development projects rather than mere road projects by integrating land-use and transport
- Adopt local area planning that allows for improved infrastructure and services for new and existing wards
Improving Energy Efficiency
BESCOM, the city’s electric utility, serves 8.9 million customers—almost the entire population of the city. However, the utility has been struggling to supply sufficient power to meet the 3400 megawatt peak demand. In 2015, due to technical challenges and dropping hydro reserves, the gap between demand and supply was almost 900 megawatts.
Bangalore consumes 40 million units every day, which is projected to increase to 74 million units by 2030. To meet this growing demand, Karnataka proposes to increase generation capacity by 22.5 gigawatts, of which 14.5 gigawatts will come from non-renewable energy sources. Distribution losses are at 14 percent, with additional transmission losses.
In order to reduce the demand-supply gap, the city needs to (1) identify and overcome information, technical and financial barriers to installation of rooftop solar PV, (2) focus on energy-efficiency and demand-side management via by promoting the use of energy efficient appliances and user education, (3) facilitate the procurement of renewables by large electricity consumers to reduce their dependence on diesel and other pollutants and (4) promote increased public participation in BESCOM’s decision making
Bangalore is at a critical juncture in its growth, where decisions today will be “locked-in” for the next 40-100 years. By addressing congestion that shifts the conversation from vehicles to people, managing urban expansion towards sustainable growth and implementing practices that provide clean, reliable energy for its people, Bangalore can move on to a path of improved livability and sustainability, and maintain its competitive status in the global economy.
