Thin line between development works, social service and exploitation

By - Anoop Jha

A case of tribal communities and regions

We need to question our own intention of doing right and doing good thing to others. May be what we think is right for someone or some community might not be that good for them as we assume.

Who is to decide what is good for whom? Is it the job of government? or maybe the Highbrow society? Or socially, politically and intellectually established individuals with their idiosyncratic ideology and philosophy having their own idea of utopian society? Is it the job of little advanced segment of society to decide what is good for not so advanced segment of society?

What could be the hidden intention behind doing good to others or some community or some region, which we call development work or at times social service?  Let’s take the example of tribal community and tribal region. Is it the shear innocent intention of sharing existing wealth and knowledge to unprivileged or unexplored segment of society or is it to exploit the untapped potential of the previously unexplored tribal region for our own advantage, is it a sincere effort to understand and document the needs and social pattern of these tribal communities or is it just to get commercial advantage by exposing these hidden communities to mainstream society, is it to help them learn utilize their own resources more efficiently or the hidden intention to exploit rich tangible and intangible tribal resources.  Is it to provide them better health, better opportunities and better lifestyle or is it  just shear gratification of doing social service.  Has that road been built to connect those hidden tribal communities to the mainstream society and to provide them new age opportunities and facilities or the intention is to extract the tribal wealth of region and exploit the heritage and culture value in form of tourism and all. 

Shy and conservative tribal communities throughout the world need very little for their living; they are an autonomous society in themselves.  They have been adapted to their environment in course of evolution and their local environment usually provides them all they need- food, shelter, social interaction, entertainment, spiritual satisfaction. Now there are few choices to make. One is to let this situation of apparent equilibrium of autonomous tribal community go ahead as usual and second to interfere and change the equilibrium either for their good or for own advantage which seems to be the case most of the time. This is a sensitive and tender issue has to be dealt with much thought and compassion. Social behaviors, norms and needs of tribal communities are mostly way different then the mainstream, so simply imposing the rules of mainstream society on the said communities might not do justice to them. For example the concept of formal education might be something totally alien to many tribal communities, so simply introducing the primary and secondary education system to those communities might not be a good idea just because we want everyone in the country to be literate, may be they simply don’t need a formal education, may be they need a different kind of skill orientated education, may be they need an education system totally different from mainstream society.  There are many such issues to address and subject of discussion.

Until they all arrive at a consensus, role of government in the mean time can be to protect the tribal communities and regions from external commercial invaders,  and provide them the health infrastructure with emergency facilities.

Walkability demands flexibility : new approach to neighborhood planning

By - Anoop Jha


Number of available choices defines quality of urban environment and experience

“planning
Walking and jogging  trail

Image shows actual walking trail around a lagoon in some part of Santa Barbara, with different route options for people to choose from, one shorter complete loop around waterbody and other longer route which also includes dotted segment. Close view  of lagoon is an incentive to walk extra length of dotted route otherwise people can take shorter route if they are in hurry or tiered. There has be different available exit choices for people, to make any pedestrian or walkable plan successful whether its planning of park or commercial complex or mega exhibition pavilion.

Tracking morphological changes and development dynamics of a City

By - Anoop Jha

Reinventing landscape in the heart of Delhi – A case of Central Park, Connaught Place

Lively and green Central Park of Connaught Place is situated right in the of heart of Delhi, enveloped by colonial architecture and streets radiating from its centre. Above, it’s a ground for recreation, occasional festivals and celebration and below its transit hub with massive underground network of metro rail system.

”
Visible changes in Central Park character
This park has gone through several physical changes, adopted new landscape strategies to adjust to the social and infrastructural needs of time, as apparent from the changing views of satellite images captured at different time of last decade. Some of these landscape changes can be due to emergence of underground metro system and in view of recent Common Wealth Game as part of city revitalization projects. Though changes in any city are not mush apparent as experienced in day to day life, but these changes can be easily noticeable if observed for a long span of time.

Study of changing morphology and understanding the built dynamics of any city or part of it can be a very interesting subject as well as very valuable input for planners to project and decide the course of future development of that city. It can also enrich the knowledge of planners and will helps understand the nature, behavior and temperament of city. Fortunately there are many tools and much data is available for the study in this direction and will be available more abundantly in the future. May be its time to review and revise the planning course structures as well in the light of emerging technologies and data inflow which was not the case few years back.

Terrace Garden on Every Roof !!

Did they say their city is green? Don’t believe them unless you see that green yourself. Seeing is believing! Common man does not understand the intricacy of complex statistics that is produced to position a city as a “Green City”. 





Lay men do not understand the matrix, criteria and assumptions that goes into judging a city on environmental benchmark. They don’t know and even don’t care how much eco friendly materials has been used in construction of their skyscraper office building, they also don’t care whether hot water supply in their luxurious bathroom of a high star grade hotel is from solar water heater or conventional power heater, star rating of their home appliances have only become a thing to be shown off. Green criteria of common urban dwellers are very simple in nature, if they been able to breathe fresh air, if they see lush green surrounding their home and their streets, from the window of their workplace, if their children can run and play in sprawling green fields, if their children know what it is called an ecosystem from their own living experience in city not learned from the text books, if they look above in the sky and see glittering bright stars on a clear night and if they look down below into a satellite imagery and see City as Green patch of land then they should definitely approve that city is green.

Urban Landscape planning with green building concept of Terrace Garden
Series of Terrace Garden in a City
Let’s start with our own home or apartments, wouldn’t it be a wonderful thing to enjoy a garden of your own which you can’t afford in your front lawn because you have to park 2 to 3 cars  there, larger the lawn larger the car and larger the paved area.  Community park of your housing society you anyway don’t want to use after long working and  travel hours, you lake time and energy, also you don’t feel motivated enough to use community or public park unless a doctor has gives you a good dose of advice recently.


How about climbing few steps in your own villa or taking a lift from your own apartment floor which leads to terrace where you would have found a lush green terrace garden where you would have done your daily meditation or Yoga and exercise while breathing in fresh air, spending quality time with family, only if they would have planned it properly as an approachable and inviting terrace garden, which is currently either not used at all or used as storage of discarded household stuffs in the midst of complexity of installed utilities and storage. So why not make terrace garden on every roof of the city. If governments across the cities shall make it either mandatory to have a terrace garden in every building with certain assistance or if incentivize this feature for being integrated in the architecture of building, that would be a great leap forward towards sustainable and greener urban future.

Growth dynamics of Urban Rural Fringe: Role of Cities as Facilitator

By – Anoop Jha

Knowledge, technology transfer and capacity building

Planning Strategies for controlled growth of a City
Urban Rural interface at fringe
Any city small or large seems to affect the dynamics of neighboring region through its constant growth externalities and internal dynamics, larger the city more visible the effects. These effects can be positive in terms of growing economic activities, enhanced affordability and quality of life, access to health infrastructure; enhanced social infrastructure etc. at the same time the effect of urban development can also have downbeat effect on communities of urban rural fringe in terms of deteriorated environmental conditions, shifting livelihood option from agriculture to business, imposed urban lifestyle and pace of living on rural fringe communities who are tuned for some other kind of lifestyle and pace since centuries.


City has moral and technical responsibility to facilitate inevitable growth of urban rural fringe in a controlled manner. It’s not only necessary for city’s own growth but also significant because cities have capability, finance, resources, knowledge, technology, technical skills, authority and experience to deal with such issues. Its city’s part responsibility to help built and nurture communities at the edge of cities through its wisdom, knowledge and technology transfer and capacity building and they should be encouraged to do that.

Creating Ecological Infrastructure for a city

By – Anoop Jha

Urban green with radiating river canal as a sustainable urban planning model

River provides ample opportunities of growth but it appears that majority of cities have not taken advantage of this dormant potential, most of the cities throughout the world have not even been able to handle the issues related to river like recurring floods, water pollution etc. forget about the utilization of river potential for the benefit of city. Thriving lush green riverfront has become a luxury which very few cities have been able to afford till now while rest of the world seems either totally engrossed in solving other urban problems and internal issues or they are content doing beautification of Neighborhood Parks. Greener Neighborhood Park is a good idea in short term but not a sustainable environmental solution for city in long term.

Cities can trade in carbon credit but unfortunately cannot trade in quality of environment of a city. What they need to do is to create a tangible ecological infrastructure for a sustainable urban environment. For a river city it is very crucial to understand the need of exploiting the possible opportunities as well as tackling the grave problems of recurring flood and river water pollution.  River system with all its tributaries is like arteries of a leaf which carries all the minerals and nutritious content mixed in water from root to leaf tip. Cities with its built mass present an obstruction in the natural direction of flow of river. Cities can be built to facilitate the natural flow of river and should be planned to dissipate the extra water from the city fabric causing flood, as quickly as possible.

A model of sustainable ecological plan for a city can be like a leaf with its arteries’ alignment opposite the river flow, Green streak emerging from river bank, nurtured by river water itself which is carried through the narrow canals in the middle of radiating greens from the lush river bank. Radiating canals into the city fabric will not only help reduce the impact of flood by providing extra water holding capacity in times of flood hence giving extra time and cushion to tackle flood problem, but it will also provide space to create lust green natural and recreational zones all along the urban canal, giving breathing space up to the unreached recesses of cities where it is most required. Aligning radiating canals in somewhat differing direction of river flow will help reduce the possibility of city flooding due to these canals to reinforce the protection mechanism, control gates can also the added at the junction of canal and river. It is like having multiple canal bank development inside the city fabric radiating from river rather than having one riverbank development or rather ignored and polluted river cutting through the city.

Biological Clock of City : Collective Dynamism of Population

By- Anoop Jha

Relevance of City Dynamism in Urban Planning

Biological clock of a city can be understood as a collective activity of resident population across the hours, days, seasons, and decades. These varying patterns and shift in activities depend on the characteristics and collective traits of cities or urban settlements like – Character of city like historic, metropolitan, ecological or place of tourist interest, industry type i.e. service, manufacturing or agro business, Economy and business of city, Trade and commercial activities, Religious activities, rituals, Public transit system availability and regulations, political stability and governance.    

A city or town metaphorically behaves like a living organism and hence each one of them has a unique signature activity pattern. In spite of static nature of cities it has lots of innumerous dynamic activities going on within it’s envelop and beyond. Pace and extent of these activities are cyclic in nature and varies across days and hours in somewhat predictable ways and seem synchronized with diurnal variation i.e. cycle of day and night, e.g. two visibly distinct peak hours of activities in any given particular day across the cities. Cities also seem synchronized to different seasons and show different patterns of daily activities as per that season, e.g. Majority of population getting off to sleep early in winters and shops being closed early, accompanied by lesser traffic and activities on street in winter w.r.t. summer.

The reason studying “biological pattern of city” can be an interesting and important are for planners is that till now, while planning or developing a city they have historically and inevitably always assumed that city is a static entity and then they prepare a Masterplan for that city, While it’s a fundamentally wrong assumption and process of planning for a city. Let’s take a fresh look on any random city, you will find that it’s a living, thriving and dynamic entity. The word morphology which is synonymous with mutation, when used in context of urban pattern itself states that city characteristically resembles a living and dynamic entity.

Challenge for the new age planners is to recognise and accept the fact that they are planning for an active, constantly changing and mutating dynamic entity called “City” rather than the past and contemporary notion of city as a static built mass, with some activities being marked in static zones of Landuse in different color on Masterplan. Urban planners not only have to consider the character of the particular city to be built or redeveloped but they also have to consider the present or future activity pattern as well as temperament of the city.

Environment centric view of Planning and architecture

By - Anoop Jha

Creating  green value chain for projects

If we observe closely, apart from the obvious socio economic benefits and unavoidable demand needs of the development projects they have some questionable effects on our environment. Any development project affects the the ecological balance of nature through its resource exploitation and project externalities, which in most of the cases seems inevitable to prevent, but its effects can be mellowed down and an attempt can be made to neutralize the negative impacts of development on the environment.

Environment centric approach is the process of planning which revolves around the aim to conserve and minimise the effect of development project. It is applicable to any scale and nature of project whether architectural or planning.  Its a process of integrating green design and planning principals as well as adopting green strategies across the different segments of, project lifespan, implementation and operational value chain of any planning or architectural project.

There are ways and means to formulize greener value chain for new planning projects like new township or business district, introducing and reinforcing green retrofit for the existing functional value chain like any random city, there are also principals to plug in green principals into the value chains into the dilapidated value chain like old cities or uncontrolled megapolis. Planner’s role is to analyse the situation and propose green and sustainable environmental friendly strategies for the city.

Emerging Strategic Trends in Urban and Regional Planning

By - Anoop Jha

Proposed strategic planning interventions

Strategic research in the field of urban and regional planning is an interesting area of study. Formulising sound and sustainable strategies require thorough brainstorming by the planners, scholars, experts, academicians, business representatives, people’s representatives, Welfare organizations, focused professional groups and individuals. It’s high time that a fresh set of strategies should be prepared to tackle the exponentially growing urban and regional problems, like population bubble, shrinking resources, growing confusion chaos in cities etc. Let’s take a look at strategies which has emerging in recent part or can be the possible fresh approach towards better planning.

PROPOSED STRATEGIC PLANS

Cross sectoral learning to increase industry knowledge base,

Multidisciplinary approach for innovative approach, cost effective solutions and swift process,

Decentralization of activities for localised autonomy and efficiency,

Single point contact from public agency for hassle free and faster processing,

Bilateral and Multilateral ties for regional consensus and holistic development,

Environmentally sustainable efforts to curtail the negative externalities of project and boost the downstream benefits

Active Resource mobilization to unlock the untapped potential of the region, population and resources

Neglected Urban River Stretches - an untapped potential

By - Anoop Jha

Ignorance to the very thing which initiated the settlement of city

River which was supposed to be the life of city has become a dumping yard of city and ignored like a backyard of house in the course of evolution of city. Most of the early civilizations evolved and nurtured on the banks of river, there must be some reason for that.
Historically City used to be a combination of human Settlement, built form and River, which used to be a complete experience in itself, and key to an autonomous existence, because people used to be utterly dependent on river for –

Agriculture,
Food,
Grazing Land,
Trade,
Business,
Transport,
Drinking water,
Other Daily Activities

Contemporarily most of the rivers in the developing countries are either polluted or ignored or both, the only activity related to that is -

Dumping Industrial Waste
Dumping city sewage and waste water
Retrieving water for drinking and other purposes

For majority of rivers in the cities of developing countries the case is that river is no more directly related to livelihood of residents of the city, insignificant business or trade activities related to river, dominance of surface transport, numerous other recreational activities and places other than river.  Even rivers are perceived as hindrance in Commuting from one part of city to the other (common feeling: God forbid the long route and traffic jams on bridges crossing river at rush hours!!!).

Need is to Understand the significance of river in forming the balanced ecosystem in the dynamics of city. Cleaning, nurturing and integrating the river stretches in to the fabric of city. There is an urgent need for Pro-river Planning approach integrating it with mainstream city life. Strict but sensible river conservation and integration guidelines need to be in the place.

Even if the Riverfront Development is not possible due to some constraints like revenue, resource etc. some of the strategies to integrate river to the city life can be –

River cleansing and maintenance through diversion and downstream disposal of city waste water and sewage
Streamlining, developing and maintaining optimum acceptable standards of clean and safe public spaces with public facilities at river banks

Providing access to “public transport nodes” from river bank at walkable distances,

Integrating every existing open and green space of city to the   riverbank    

24X7 Surveillance and easy help facilities 

Light Pollution - A nuisance seemingly out of control

By - Anoop Jha

Light Pollution propelled by shear lack of awareness


If you will conduct a survey asking city dwellers, including educated as well as  illiterate population of any developing country to name the types of pollution they know, they tell you water and air pollution, few of them might also tell you Sound pollution but, you will find only handful of population even aware of the phenomenon of light pollution. This is unfortunate that people don’t even know about the price they pay in the name of industrialization and development, not even aware of their rights to live in a healthy pollution free environment.

There is a very simple and straight reason for all this unawareness - there is no curriculum throughout the hierarchy of education ladder that teaches the existence, cause, effects and resolution of light pollution. At least it wasn’t included in course structure in recent past. Another reason of lack of awareness is that majority of young population who were born and brought up in city and have not visited or spent time in any rural area or outskirts of city, they don’t even know that how does a clear night sky look like. They haven’t observed stars in real, lying on the terrace of their home, or in front lawn of their home, because majority of them live in compact flats in the comfort of controlled indoor temperature, they have only vague memories of star filled sky from a movie or childhood imagination of stories that their grandparents used to tell them. Possibly Light pollution is more of intangible in nature and awareness, hence planning communities as well as city authorities are more concerned with the tangible issues whose effects are visible and well known by citizens like water and air pollution.    

Acute phenomenon of light pollution calls for strict urban lighting Guidelines and Regulations whether people are aware of it or not. Parallelly an education drive needs to be conducted throughout the country to make people aware of the illness of industrialization, massive unregulated developments, their rights, emerging global phenomenon.

Local Ecosystem : Model for adaptive growth

By - Anoop Jha

An autonomous and sustainable model for planning

Understanding the intricate pattern of  local ecosystem of any region which is adjustable and adaptive to its constantly changing environmental parameters like micro-climate, inhabitants, pace of activities, external tangible influences etc. could prove to be the key to future sustainable model for Urban and regional development. 

There are ample of example of such ecosystem throughout the world with  its peculiar challenges and solutions. ecosystems can be as small as an small island or a patch of land on a river bank, or it can be as big as a regional watershed catchment area of forest of Amazon, but each of these autonomous ecosystems have some kind of  similarity  which is absorptive capacity of these ecosystems, they seem to have inevitable capacity to nurture and absorb the growth within its somewhat flexible envelop. 

Natural ecosystems try to maintain a unique environmental conditions necessary for its existence from its constant physical and chemical activities. For example, river bank of an urban settlement which acts as the only grazing land for  buffaloes and cows of the small villages trapped within the city fabric in the process of urban expansion, can be an interesting area of study related to ecosystem.It is more or less similar cycle of activity flux everyday in the somewhat flexible envelop of this river bank grazing land, though constantly being influenced and invaded by the development activities of city and natural cyclic activities like annual flood. another example can be the Large forest of Savanna, which apparently seem calm from a distance but  buzzing with life cycle activities of flora and fauna inside its dense green envelop, constantly nurturing, changing, adapting  and absorbing the growth, while maintaining its ecosystem. Urban and Regional Planner need to study, document, analyse, extract, and implement the similar autonomous model of growth and planning for a sustainable future of cities.

Perception of space – a function (f) of Space

Regional and Locational shift in Perception of space

“understanding
Space function and origin
Perception of space in terms of physical location of observer plays a crucial part in understanding planning of urban built form and is a vital part of Urban Planning, but the roots of such perception emerges from regional level. It is also related to conditioning, space perceived by residents of mountainous, hilly and undulating terrain are totally different from space perceived by person living in  flat terrain. Similarly space recognized by a person who spent most of his life in sprawling rural setting  can be totally different than a person living in an urban setting, It can be either” a not so pleasant shock” or “a surprise” or “an aspiration” for an individual while changing their location from hills to plain or rural to urban or vice versa. Usually what happens is that people constantly living in mountainous and hilly terrain witness only finite view due to restrained field of view by mountains,  hills and valleys, and when they occasionally come to plain and see that there is no limitation on the field of view, when they realize that they can see upto the horizon, it’s a pleasant shock to them.

Similarly when a resident of sprawling plain terrain goes for a vacation to some hill station or otherwise, they find it as a one of the finest moments of their life, primarily because of limited and ever changing field of view provided by hilly city,  they have a totally different experience of space that is finite which they have never experienced in life living in plains. Similarly a person living in a rural setting with sprawling, sparse and low-rise settlement when encounter with a city with medium to high-rise and dense built form and architecture, its not the rush of city that strikes him most, it’s the “Built Form” that strikes him dumb, he curiously looks out of the window of train and bus and cab, to see the buildings touching the sky, public spaces formed and enclosed by surrounding buildings. Suddenly he finds himself enclosed and restrained in the built form of the city which provides finite field of view with claustrophobic environment which is a paradigm shift in perception from the earlier experienced freedom of unlimited perceived space of rural setting.
