My big idea. Work the doubling factor (Ortiz, et al) into law, engineering and architecture. Stop cities in their tracks and offer unlimited density and therby guarantee an unfragmented wilderness, or at least the potential for restoring one.
Take any annual percentage rate and divide it into 70 to get a rough estimate of the “doubling-time factor”. It is an easy way to question the presumed benefits “growth rate” figures. For example, a 7% growth rate of a population would double the population every ten years – thus require double bottom line questions about who (or how) would we pay for the doubling of the number of schools, the efficiency of all forms of environmental facilities, and so on.
*The doubling time factor is the period of time required for a quantity to double in size or value.

A Common Vision
As Mumbai matures and harbors aspirations of becoming a world-class city or an international business center, the City needs to engage in ecological urban design and accountable urban planning. Urban planning is a means to create a citizen-defined vision for the city’s future that is implemented by responsible public and private leaders.
Much has been said recently about the need for improving governance of cities in India where there has been little attention paid to the planning or design of cities. Cities throughout history – especially in democracies — evolve from a state of chaos and irresponsible governance (where mostly the interests of the powerful take precedence over the city’s general welfare) — to a progressive state where the better informed and educated citizens demand and receive political accountability for better urban life through effective planning and urban design.
Mumbai at present is in a transitional phase in its urban and political history where few enlightened and committed citizens and civic leaders are learning about the prospect of a better city in the future. Better than its current physical, social and political conditions such that through gradual transformation in another generation Mumbai could achieve its citizen-defined aspirational goals.
What is critical for such an evolution to start now is that the various citizen and advocacy groups, the academia, the private development sector, and the political and government leaders come together in a broad-based coalition to initiate a process of creating a Mumbai 2040 Vision. Such a future vision will need a supportive Strategic Urban Design/Ecological Master Plan that identifies the necessary implementation strategies, including the coordinated roles to be played by various sectors and agencies to achieve the vision.
Democracies present messy and inherently conflicting and competing challenges. Yet, through early-stage consensus-building processes, defining and adopting long-term common goals and vision are not altogether impossible even as they may be difficult. Yet, too, it is the difficult and hard things one does to achieve in the end something meaningful. This holds true for communities and cities too. Mumbaikars will thus come together to engage in a process — possibly arduous — to define a common future vision of their city.
Which Mumbai or Which Parts of Mumbai?
With the rapid and explosive urbanization of the city, Mumbai has spawned off a Navi Mumbai and several other distant and close urban agglomerations such as Thane, Andheri-Versova and the Bandra-Kurla complex. A clear question to be addressed up front is for which Mumbai or which parts of Mumbai would this future vision be created. The answer lies in the consensus Mumbaikars would achieve for the area of study. Ideally such a study area should cover the central and south Mumbai for regional recommendations, and for more focused recommendations an area such as south Mumbai. Even more detailed and fine-grained recommendations can be based on study areas comprising the wards, sectors or neighborhoods of Mumbai. The important point is to select a large enough area to better account for the city’s unique ecological considerations.
Why A Strategic Urban Design/ Ecological Master Plan?
Historically Mumbai was put together by joining and connecting seven islands in the colonial times. With rapid urbanization and ever-increasing built-up areas over time there is little vacant or open land today for the city to stay in balance with nature. The most recent major flood (2005) is a disruptive reminder of why a major development priority for Mumbai will be to create balance between growth and natural ecology.
Among the Indian cities Mumbai also has a unique social ecology – whereby historical growth patterns have resulted in close juxtaposition of high-end neighborhoods and the economically-productive yet hygienically-challenged places of homes and industries. A major reason for such growth patterns in the city is economic where Mumbai as the nation’s financial capital continues to attract job- and opportunity-seeking population from its rural hinterland and indeed the rest of the country. Any future vision of Mumbai will thus also address its unique social challenges ensuring that its market-driven growth is in balance with the need-driven places for living and work.
Along with the city’s own efforts, national growth policies that effectively bring jobs and urbanization to the villages will also be essential to reduce growth pressures on Mumbai. Notably, programs like PURA (Planned Urbanization of Rural Areas) would be important for Mumbai’s evolution towards achieving its long-term vision.

Other than its unique ecology and social structure, there are other factors as well (such as limited physical space for the needed transportation capacity) that further distinguish Mumbai from other Indian cities. Carefully analyzing such factors will inform the creation of solutions that are uniquely suitable for Mumbai. While specific targets may be set to increase the city’s supply of jobs and housing, the number of healthcare and educational facilities, or the number of infrastructure projects, achieving numerical parity with other world-class cities alone will be inadequate for Mumbai to achieve its aspirational goals.
That’s why Mumbai needs a Strategic Urban Design/Ecological Master Plan (Strategic Master Plan) that would improve urban life and achieve balance with nature. There are many successful examples of city design from across the world that Mumbaikars could choose from as appropriate urban design solutions for their city.
With the extensive transportation improvements being planned and implemented in the city, appropriate urban design would provide – for example — better pedestrian access to stations for the residents at the street level. One can imagine a network of wider sidewalks in neighborhoods that is integrated with open parks and plazas, around which are located residential, commercial and mixed-use buildings in settings that enhance the sense of place and the quality of urban life. Appropriate urban design would also determine the most suitable land uses for transit routes and stations – especially where new development may replace the established development.
The new parks and open spaces would be located strategically in low-lying areas to give the city much needed breathing space and the room for dissipating flood waters to escape with little harm to city life.
Appropriate urban design would also achieve good urban life across the city equitably.
A Strategic Master Plan would thus provide multiple tangible and perceived benefits to the city that would raise its attractiveness for urban living and for businesses. Achieving the quantitative aspirations would then add to the city’s draw in the world.
A Strategic Master Plan would go farther with new urban policies and better governance. Mumbaikars engaged in Plan development would expect more accountable leadership, and by demanding it will gradually get it too.
What is critical is that a citizen-defined Common Vision and a citizen-supported Strategic Urban Design/Ecological Master Plan be adopted for Mumbai to most effectively meet its aspirations.

Affordable Housing Strategy:
The city has a housing shortage of 2.62 million units in 2009.This will almost double to 4.47 by 2025 if not addressed. We need to develop new strategies and tools to solve the crisis.
Develop a Climate Change Action Plan
Many scientists agree that even the current level of carbon in our atmosphere is going to contribute to changes in our environment. So even though it is important to mitigate climate change or reduce the carbon emissions. There is an urgent need for adapting Mumbai City to climate change impacts and a future of extreme climate events. It needs to start with a comprehensive scientific analysis and modeling to understand the potential impacts of climate change on the city.
Improve Public spaces & Become Pedestrian friendly
Creation of grand cultural destinations & public spaces for all the citizens of the city … There is especially a need to make the city more pedestrian friendly and invest in pedestrian infrastructure. The city also needs to focus on Non-Motorized Transit Infrastructure.
The world’s urban Population is set to double …
The world’s urban Population is set to double from the current 3.4 billion to 6.3 billion by 2050, according the United Nations. India will be at the forefront of this urban rise. Keep in mind that the scale and pace of the urbanization that India is going to experience in the coming century is unprecedented by history. It requires us to act fast or we will have to deal with social and environmental crisis of disastrous proportions.
The present set of problems that the world faces in area of environment, poverty and health; demands that India craft a vision of an entirely new developmental model. The manner in which cities have grown in the past thousand years has been acceptable up till now. But we are at a tipping point at the moment and we need to choose a new path.
Think about it- The world simply cannot continue to grow in the current model. The current model of development that is employed in the most advanced economies of the world doesn’t allow all the population of the world to use its resources fairly. For example – Today even though less than 5 percent of the world’s 6.45 billion people live in the United States, this small population consumes roughly 25 percent of the world’s resources. According to some estimates, the average American consumes five times more energy than the average global citizen, 10 times more than the average Chinese, and nearly 20 times more than the average Indian. If everyone in our planet were to live the average American lifestyle, then we would require 5.3 planets. The current developmental model only allows the rich to live a certain quality of life at the expense of the poor.
So clearly, the world simply cannot develop in the current model of growth. It would simply be implausible to move our entire population towards a reasonable level of “Human Development Index” with the current models of growth – Simply because we don’t have resources to sustain it. So does that mean that we stop all development and halt the progress of our civilization? Well no. It means that we need to conceive a brand new type of development model.
At this point , I also have to highlight that cities in many ways are the appropriate model for the future. Cities, in fact, allow all of us to share resources and they are the most efficient way for human civilization to distribute its resources fairly while conserving its important flora , fauna and biodiversity. But we need to relook the way we perceive the city.
In the current developmental Model – we seem to talk about a host of non-renewable resources. But we miss the most important – Land. Arable land that grows food and nurtures the planet earth and its inhabitants (both humans, and other flora and fauna) is limited. Without food, humankind cannot survive; people will die of hunger. The current model of Urbanization is threatening our food supply and the existence of our planet. We need to conserve land desperately and come up with a new type of developmental model.
The future urban development model of the world will conserve land vehemently. Instead of converting hundreds of acres of farmland into development zones like today; Urbanization of the future will have to be creating farms and forests in already developed zones. Multi-layered high density towers will be the way to achieve this development model as they are the best way to ensure compact urban centers. In today’s times– High density development has been equaled to skyscrapers which are only seen in an iconic manner. But high density towers will have to be seen as a tool to reduce our ecological footprint. The design and form of the high density towers of the future will again be different. The high-rise of the future will be small cities in themselves and will be self sufficient pods. The mega towers of the future will have multiple levels of gardens, parks and farms in the sky. They will have vertical networks of mass- transport: The elevators of today will act like networks of mass-transit similar to subways / rails of today and will transport millions of people.
Instead of just using energy – our cities will be producing energy. The cities of the future will conserve every drop of water that falls on us. In essence, the cities of the future will have to increase the bio-capacity of our planet instead of reducing the earth’s bio-capacity. The key task of the infrastructure provider of the future will then have to be about adding to bio-productivity of the planet. At that time – Existing cities will be villages and existing villages merely historic sites. The large quantity of the agrarian economy will be centered in these areas. Most of the world’s population will live in these areas and will rightly leave large parts of our earth for other species .
The megapolis of the future will require a whole new way of thinking, a whole new set of rules and laws. We will not have land rights but we will have space rights since land will be extremely precious. The political reality will be different too. The lowest strata of our society will be treated with great level of respect. The government will provide social housing for the poor like any other basic infrastructure provided by them today.
India’s young population is going to be a great asset in this age. Europe & North America is already aging rapidly and birth rates are far below those necessary to maintain current population levels. Because of its one child policy, China is also set to age rapidly in about 20 years. But more than half of India is below 25 and growing. So India’s youth will be an asset to the world.
In this future – The world’s people will be global citizens due to huge levels of inter geography – migration; and collaboration between people of different regions paving a way for a world with little conflict. There will be tremendous intermingling of people from different cities much like global cities of today and a new global state will evolve. Our talented young people like others across the globe will move between these megapolisis as new economic opportunities come up .

Often, when framing urban policies we in India …
Often, when framing urban policies we in India adopt a view where we try to create policies where all the lobbies are satisfied, .Most times this may not necessarily translate to a great vision. When you analyze a city like Bangalore, there is an inner older city and the outer city which is mostly new developments. The old Bangalore with tree-lined roads and little gardens has always had great appeal. This character of Bangalore, largely shaped by these tree-lined streets, is slowly vanishing, given the shortsighted way the city seems to be cutting off its trees.
The new development plan is going to further destroy this invaluable quality of Bangalore as the garden city. The widening of the roads, the cutting down of the trees, the new high density plans will wipe out the Bangalore that we all love and remember. I am all for urban redevelopment and change. But we can focus on high density development and new infrastructure while conserving the valuable features and heritage of our cities. I think the idea of creating a single law for the old and new segments of the city is not an intelligent solution.
I believe the inner city with its charming character should have been preserved as it is. It should have been the nucleus and they should have kept the FSI or density constant in these areas. The major metro lines, infrastructure projects and higher density development should have been focused on the outer city circle. I call it the “Medhu wada” concept- The old charming Bangalore should be preserved, almost as it, in the inner circle and higher density outer city with new infrastructure should be created as a ring around the existing city. In that way, you could have kept the intervention in the exiting parts of Bangalore to a minimal. Of course you would need a few crisscross expressways and an underground metro system. This way we could have retained the older charm of the city and the outer city could have been designed like the state of the art mega city of the future.
