Making clay country roofing tiles: Demo

After I wrote “Clay country roofing tiles” in 1987, I suggested an NGO to conduct a demonstration-come-training programme for their housing project for the tribal in Raigad district. Their target group was Katakari and Thakar tribes.

For this demo I brought two young men, Baliram and Deva, from village Amiyar in Bharuch district in Gujarat. They belong to Bhill tribe called “Vasava Koli”. I had already known them for quite some time. Vasavas are better educated than many tribes.

Vasavas practice their skills of clay tile making at household level. Their technique resembles to one that I had seen, during my childhood, with the potters at my native village in Konkan Region, decades ago.




The illustration 1 shows the hamlet “Navi Fali” – a part of village Amiyar, where Baliram and Deva live. It is evident enough that the houses are built of organic, locally available materials – clay, bamboo and wood. The settlement is built by self-help and community participation.



Illustration 2 shows the cattle sheds, which are suitably built for the purpose.


Baliram and Deva received good facilities of accommodation, food at the mess, travel and to work at the NGO’s campus in a village.

They scouted the surrounding area with the staff of the NGO, found suitable soil, which was transported to the work shed at the campus. They produced about three thousand tiles within three weeks.



Illustration 4 shows the demonstration work in the shed provided for the prepared soil, tile making and drying the raw tiles.


Illustration 4 shows the burnt clay tiles. Persons in the picture (from left to right) are a visitor, a lady office bearer, two staff member (one in the rear), Deva and Baliram.

Observation
1. during the demo the NGO did not invite or bring the adivasis – Katakari and Thakar – either to watch it or for the training.

2. The staff (social workers) occasionally visited the demo. None of them tried their hand at making the tiles.
Knowing the urban ways, Baliram and Deva as well s myself were indifferent about it.

3. I don’t know if the NGO did ever document the whole operation – labour, logistics, and utility – price-value-cost-benefit – of the product, perhaps other than voucher for accounts purpose.
Needless to say, NGO used substandard (i.e. cheaper) Mangalore tiles for the housing.

4. NGOs, either in Gujarat or Maharashtra, are not interested in the tribal skills, knowledge, their self-reliance, and above all their self-respect. One can safely generalise this statement.

Gandhism (गांधीवाद): Marathi Poem

Gandhism

Gandhiji wore loincloth of Khadi
We patronise marketed Khadi
That’s our limit of Gandhism –
Don’t shed crocodile’s tears.

गांधीवाद

गांधीजी पंचा नेसत होते.
आम्ही बाजारू खादी नेसतो.
ही आमची गांधीवादाची मर्यादा --
नक्राश्रू ढाळू नकोस.

Tata's Nano car (Modern Haiku)

Tata's Nano car (Modern Haiku)

Behind your car
I am dragged –
fallen leaves.

(For a farmer even fallen leaves are precious. They burn them to keep warm. It is used as (compost) manure. But in modern India (call her Bharat or Hindustan) modern maharajas – the corporate – like Tatas – have emerged. What value do they have for - whether farmers or fallen leaves? Read more) (Translation by the author)

पाचोळा ( आधुनिक हायकू)

तुझ्या मोटारीच्या मागे मागे
येई मी फ़रफ़टत ....
पाचोळा।

(शेताकरयाला पाचोळा फार मोलाचा असतो। त्याची शेकोटी होते। त्याचे शेतासाठी (कम्पोस्ट) खत होते। पण आधुनिक इन्डियात [वाटल्यास भारत म्हणा किंवा हिन्दुस्तान म्हणा] टाटा सारखे आधुनिक राजे महाराजे तयार झाले आहेत। शेतकरी की पाचोळा, त्यांची त्याना काय किंमत ? पुढे वाचा )

Cow dung and paddy: a critique of Amartya Sen


Cow dung and paddy: a critique of Amartya Sen
Challenges of 21st Century

by Remigius de Souza



------------------------------------------------------------------------------
“Everything, in this world, exists in order to culminate in a book.” —Mallarmé (1842 – 1898)
“The evil that is in the world almost always comes of ignorance, and good intentions may do as much harm as malevolence if they lack understanding”
– Albert Camus
-------------------------------------------------------------------------------------------------------------------------------------------
(Key words: Land (with waters) is the source of Life and the sustenance to all living beings, and culture to humans. Peasants – the landless and the landholder alike, the artisans known as twelve ‘Balutadars’, and the forest dwellers or the tribal, which amount to 900 millions including those languish in the city-slums. Development is an ongoing process and not an abstract economic theory. When means and goals are same then there is possibility of development: here land is the means and goals, so also the peasants. Environmental-Ecological-Energy Cost (E-E-E Cost): It is not enough to count cost-price-profit (loss) in currency any more; it is already an outdated mode the economists have been following.)

I AM BROWSING Amartya Sen’s book, ‘Resources, Values and Development’ (1984), a selection of his essays from 1961 to 1984, republished in paperback in 1999 (OUP), after about fifteen years. Perhaps the author and the publisher did not see any need to include subsequent essays, if any, a sequel to the theme of this book, perhaps due to the restraints of economy.


At the start of the introduction, Professor Sen declares, ‘Much of economics is neat and elegant; but some of it is not. The essays included in this volume belong to the later category (p.1).’ It is because, I think, they are holistic. They relate mainly to development economics that take into account many aspects. I, of course, skip theories, equations, diagrams, tables etc., as I am not equipped to comprehend; I look for fiction. I, however, find something amiss, something desirable to the heart of a peasant. Hence, without defining or theorising I straight go to an example:

In the Chapter 13: Rights and Capabilities, Section 3: Capabilities, I notice:
‘Consider a good, e.g. rice. The utilitarian will be concerned with the fact that the good in question creates utility through its consumption. … But that is not the only thing it does (p.315).’ he further writes, ‘Four different notions need in this context. There is a notion of a good (in this case, rice); that of a characteristic of a good (e.g. giving calories and nutrition); that of functioning of a person (in this case, living without calorie deficiency); that of a utility (in this case, pleasure or desire fulfilment from the functioning in question, or for some other functioning related to the characteristic of ice) (p. 316).’
---------------------------------------------------------------------------------


AS I READ THIS PART, I wander away from the book into the realms of my perceptions, experience, information and impressions that I gathered during my journey through places, events and time. It is also keeping in with an idiom in my native tongue, Konkani, “you need not check every grain of ‘rice’ in pot if cooked.”

Sometime around 6500 – 5800 BC, the archaeologists say, people in the Fertile Crescent in South-east Asia domesticated rice. That included a part that we now call India, Bharat, or Hindustan as per our convenience. However, even to this day the tribal, in the backyard of Mumbai, cultivate wild Jowar – millet – and use it for various purposes: grains for food, its stocks that grow 7-8 feet for fodder and in housing.
----------------------------------------------------------------------------------



I TAKE THE EXAMPLE of Konkan, a rice-producing region on the western coast, where I was born, and grew up on paddy farms during my formative years. For a peasant, her homestead is the yard around her adobe abode with plants, fields, groves, grassland, hills, and of course, the community well, a stream, water reservoir if any; and a cow, goat, chickens, cat, dog or bullocks join her kinship.

During all the dry days, besides other chores, she collects cow dung, brushwood, dry leaves, which go for fuel and/or manure in a compost pit. She collects even the ashes from ‘Chulha’ – cooking hearth, and ashes from the burnt leaves and spread in the farms. For the peasants this is ‘conventional’ agriculture, which continues in many places. The western and the westernised call it ‘non-conventional’ or ‘organic’ agriculture.


In between, there are four months of monsoon that witness hectic activity at home and the fields – transport, process, sowing and caring paddy, other grains and vegetables.

The harvest brings the work that involves transport, process and storage. For example, there is a process for parboiled rice. Until few decades ago, they used the wooden grinding wheels (Ghirat) at home to remove husk, similar to stone-mill (Jaate) for flour. Now they take paddy to rice mills. They take home even the husk of the ground paddy. They feed the finer husk after boiling to the chicken / cattle. They mix the course husk in cow dung to make ‘govari’ – a flat cow dung disk – for fuel. Paddy straw is stacked in a mound (Koodi) around a wooden bully 10 – 15 feet high. It is stored for cattle feed during dry days, as green fodder is available during monsoon.

The seeds, paddy, parboiled rice and rice are stored according to the quantity in a bamboo mat silos, or in paddy straw bundles (Moodi). Silos are covered from outside with cow dung wash. The bundles look like huge pumpkins of about three feet in diameter. The paddy straw cover is about three inches thick when compacted. They use a hand-made paddy-straw rope to tie around the bundle, compacted by using a wooden batten. The vertically tied rope looks like altitudes on a map of the globe. Indeed, it was a beauty, a work of art (or craft!) now perhaps lost forever. Paddy straw is also used for roofing in some cases, as may be seen near saltpans to cover and protect the un-disposed stock of salt in the open, during monsoon.

This is a very brief description of few details of peasants’ actions related to rice in the example above. Simple and ordinary as they may seem, there is a complex interrelationship between resources, values and development, which modern economics may not have fully explored. There is much more: besides skills, tools, processes and products related to rice, so also number of other “utilities”, not only for livelihood, but also culture/s of peasants. This has been going on for generations, for ages.

“Consider a good, e.g. rice”, again. A few hundred miles north of my birthplace is Riagad District. Here, for example, in the coastal plains, the peasants don’t plough the paddy farm, but directly broadcast the seeds. They also use water-flooded paddy terraces to farm favourite local specie of fish, ‘Jitada’, by digging pits that retain water for few months after monsoon. People have used diversity and adversity both to their advantage discovered by ‘collective creativity’ and not by theories. In the land of great diversity that is India, what variety and wealth of knowledge, skills and practices must there be.

However there is no time or will among the ruling minority, which is obsessed with western-style ‘development’ of capitalism with a benevolent name ‘duel economy’, hence, no records of “Intellectual Property Rights”, which may come up or be ignored in future; every time there may not be cases like Basmati rice, Neem and turmeric. The theft and smuggling of plants and herbs out of the country that is taking place is apart! While the elite enjoy a status of neo-Brahmanism, the 900 million peasants are like Shudras, or second-class citizens, or an underclass; that’s ‘duel economy’! Without right empowerment how would the peasants care for the vanishing precious biodiversity?


With industrialisation, and without appropriate rehabilitation, it is not only the loss of the people’s knowledge, tools, and skills and the indigenous seeds, but also the loss of environment of the natural habitat. The ground water is going lower or is getting poisoned. We do not hear the chorus of frogs during monsoon nights any more. We were shocked to hear a hundred peasants died at a stroke in Karnataka by consuming crabs that had concentrated pesticides in their bodies. What will be the fate of the land, waters and the people when the SEZs (Special Economic Zones devised recently to take over agricultural farms in India) will become operative in near future?

The governments, at the centre or states, have shown total apathy for the past six decades to organise and implement rehabilitation of the peasants, while bringing in and supporting industrialisation with their ad-hoc policies, projects and the laws. Why is this apathy? It is only because the peasants and the farming communities in six lakh villages is not an organised sector like commerce, trade and industry, which can twist government’s arm at a single call. Are the peasants on their way out to annihilation? It is as mute a question as the peasants.

Perhaps the plain reason for this failure of the government is that the British Raj did not leave any formula as their legacy while parting; or it failed to invent any on its own; or it failed to imitate others. It failed because it failed to do necessary fieldwork. It is easier to produce nuclear weapons or space ships, at any cost. How could anyone invent a theory or an equation or a formula for application for such a great diversity and the great disparity?

Certainly, Sen must be aware of many examples as one cited above, and the anomaly thereby, as may be guessed from his writing. However, what will happen to economics, if it has to take into account the above example? It will have to count also the “Environment–Ecology–Energy Cost” (EEE Cost) of the conventional agriculture of the peasants, here and now, at least in the Twenty First Century, and revise all its equations and formulae, hypotheses and rationale. It will have to re-write the equations after assessing the “EEE Cost” of all the industrial products.

The example cited above clearly shows the practice is labour intensive, uses local resources, and conserves the soil regularly by its rehabilitation, and so far it is a model of sustainability. The capitalist society and its culture of production and consumerism beyond needs, and the waste thereby, do not envisage this aspect. Even by conventional system the peasants do not get a fair deal, even by the governments. The experts, even those rebellious against the system, are recognised by awards not by action. But who could guarantee the theories work? As Paul Valéry says, ‘there is no theory that is not a fragment.’

See, for example, the Census Survey of India 1991 (Census 2001 is not yet printed). It defines, “persons engaged in household duties, students, dependants, retired persons, rentiers, beggars are some of the categories grouped as non-workers” (Section 10, part 10.2). This seems to be applied to both urban and rural populations. How crude? Among peasants, the women share major responsibility at farms as well as home; the help comes from the aged and the children – students, dropouts, or those never enrolled. The peasants, even if aged, never retire unless invalid. The village data, if checked, will show substantial number of non-workers. See also the number of inhabited villages in the Census data. How do the people survive? Where do people go?


How reliable are such data that may be extensively used by economists, other experts and planners to shape the fate of the people, but never reach the peasants? The amazing fact is the government may approve to send a man on the moon, but never sends complimentary copies of the Census Survey to the Gram Panchayats so they can scrutinise its work: only the peasants are qualified to do it, but they are languishing in illiteracy – innumeracy.

The peasants are not aware of their status recorded by the government every ten years. And now Census 2001 is available only in electronic form. What would be the response of the peasants, particularly women, who feed not only their families but also the nation, to their status of ‘non- workers’ along the beggars, in the country that is so rich in resources? Whosoever may be responsible, the hypocrisy is unprecedented, it has no match anywhere.

Having, of course, a will, in the modern times, and by hard work, the government can open many new avenues and areas to the peasants to elevate their skills, knowledge, livelihood, sustenance and self-reliance.

------------------------------------------------------------------------------------
Taking the example of rice, we name a few options as a reminder:


Rice husk: cement; Paddy straw: cattle feed Paper; Rice bran: bran oil; Defatted bran: Agricultural farm;
Animal waste and farm residue: methane gas, manure; Waste water: filtration plant --- algae pond (nitrogen-rich manure) / fish pond; Recycled water: farm/ kitchen garden;

Plantation: fruits / fibres / spices and condiments / medicinal plants / aromatic plants / colours and dyes / gums and resins /paper / timber / and conservation of vanishing species; and now bio diesel (e.g. Jatropha);

Land: conservation, restoration, use of soil testing kit, and as the subcontinent now is known to be earthquake prone, to be prepared for self-help;

Waters: conservation, recycling, aquaculture, health, recreation, use of water testing kit, and water management in the times of floods and draughts by self-help, having known that the government help does not reach in time to save life and property.

Market: (1) arithmetic to derive the price-cost-value-benefit of their actions and input into their work, sustenance and the way of living; (2) idea of modern ‘economic developments that are conducive to a proliferation of middle-men, where commodities take over things, even humans, and prices from values; (3) work to master the market, neither to serve it or patronise it.
These options should be the focus of education and main part of the curriculum for 900 millions peasants and 600,000 villages in the country, and not the British-made schooling, which is still being followed by the authorities and the departments.

-----------------------------------------------------------------------

Having a will and courage, the government, as it has vast infrastructure, it turn every village into a Special Agro-tech Parks (SAPs) across the country. Taking a clue, if need be, from the West that sent the youth to the armed forces, or China’s example of ‘Cultural Revolution’, India too can develop on an indigenous tool, which is partially in operation.

Introduce a compulsory ‘internship’ of six months for all the candidates who go for Diplomas, Degrees, Masters and Doctorates from every discipline of higher education, without reservations. They must go to the villages and work with peasants and SAP, without any stipend. They should support themselves by using, and also testing, their learning of 15 / 17 / 20 years of formal education. (The likely fallout that there may be a countrywide wave of ‘bribery and corruption’ to escape the internship, or otherwise we trust the Response-Ability of the younger generation, irrespective of all the prevailing waves in the country!)

Deliver the “Pro-poor” products, not the promises.
Give them the ‘fishing-hook’, not the fish.
Be the facilitator, being democratic government, not a ruler.
Return the land to the peasants, by their ancestral right, don’t sale to the corporate.
Start six lakhs SAPs for six lakhs Villages of India on war footing.

Context, Process and Content (Story)

Comment on a Comment by Harini on “Illiterate farmer women of Andhra”.

Any project has three elements: Context, Process and Content.
We, in Terra Incognita Indica, are right now critically concerned about Context and Content, which are elements of any project than its Process.

Our “NEEDS” are more important at this critical time in history than the “WANTS” of the few who constantly continue to upgrade process – technology – that has no effect on context to living sanely and livelihood of the billions.

Dheboo Ghosh, during one of his workshops on ESP held in Mumbai, told us a story:

Once upon a time there were two cities on the two banks of a river. Both city governments decided they should build a bridge for the convenience of the citizens.

They built the bridge. Everyone involved – cooperators, engineers, bureaucrats, contractors and the citizens – were happy. They had received their rewards.

But in a course of time the bridge developed serious defects. They tried to repair it, but no use. Hence they decided there was something wrong with the process – technology, and therefore proposed to build a new bridge. What could be the fate of the new bridge? They were checking the process instead of the context and the content.

Everyone of the participants understood the moral of the story.
If it is still not clear: Consider what was the context and content of the invasion on Iraq by the Us and its buddies?

iTECHNOMAN

Self-portrait by Remigius de Souza, Mumbai, India (1972)
Colour on handmade paper 9"x 12"
© Remigius de Souza

You may read or interpret iTECHNOMAN” in various ways that you may prefer.

Remi (Remigius de Souza) is marginally literate, not only in computers, but also in any of the Arts and Literary disciplines.
He began to learn writing Letters and Numbers of his vernacular language MARATHI on a slate, at his native village in Konkan.Simultaneously he also took lessons in his basic needs, which are farming in agriculture, horticulture and aquaculture; mud house building and its maintenance; and spinning and handloom weaving of cotton fabric: FOOD, SHELTER and CLOTHING.
Industrial society has failed after centuries to reach this ability or level, which is mentioned above, to impart education to any citizen anywhere in the world, certainly not in India.
Decades later he learnt computer programming in an antique language “1401” in an intensive course of one month, which was given by Tata Consultancy Services (TCS): that was the only formal training he received in computers.

Illiteterate Farmer women of Andhra (Comment)


IN THE FIRST PLACE, They should show these movies to the ruling minority in India – politicians, bureaucrats, experts, specialists, planners, the educationists and the self-proclaimed leaders, and the urban elite – before showing them to the world.

This “Soil Unrecognised Indian” is now being seen…

Building with Earth: a notable Textbook



Building with Earth: a notable Textbook (Book Review)
by Remigius de Souza 
------------------------------------------------------------- 

BUILDING WITH EARTH
Authors: P. Doat, A. Hyys, H. Houben, S. Matuk & F. Vitoux (CRATerre, France),
Translators: Asha Puri with Manu Bhatnagar, Publishers: The Mud Village Society 24, Chitra Vihar (FF), New Delhi 110092Price not mentioned. (PB). 
-----------------------------------------------------  


TO MY QUERY, which was directed to CRAterre [in 1990], when I received an answer, I had sighed with relief. My question was if I could use compressed mud block for building in the region where there is saline soil. The answer was negative. The cause of my relief was in this part of the world the “machine” – even the manually operated one – will not help to build with mud, and that there shall be little less intervention by the elite class, of architects at least, in the people’s initiative to build their own houses; perhaps temporarily for the present.

For I cannot foresee what may befall upon people – peasants in future, save annihilation, at the hands of more powerful societies with weapons of market economy, information technology, mass media, intellectual property rights, etc. at their disposal.

Because in the food – farming – sector already the hybrid seeds which require more and more water, chemical fertilizers and pesticides and deep ploughing mechanized farm implements have found their way in this region. It is not without causing death of the earth and indigenous seeds which helped the sustainable ecology until now. CRATerre’s answer had described that the only possible method was to build by hands and the manner, which in fact the people of the region had developed and practiced over generations.

THE EARTH TOUCHES every facet of Indian life, from humble lamp burnt with vegetable oil to housing, and from ‘Chulha’ – hearth – and utensils to farm and water management. The universal building material ‘earth’ is now being termed as ‘non – conventional’, thanks to the environmental revolution which started in the modern times in the industrial civilization of the West, and is slowly being accepted by the advanced societies.

CRATerre – International Centre for Research and Application of Earth Construction – is an NGO, works in research, training and implementation. It was established in 1979 by the co–authors of this book. The present work is the historical and technical research, standardization of tests, analysis and trials. CRATerre Peru researches on earthquake – resistant building systems and has a specialized documentation center

‘Building with Earth’ gives sufficient ‘scientific base’ and also ‘industrial footing’ to the subject, which the educated look for. About 300 pages of the book are abundant with tables, graphs, illustrations in diagrams, drawings, details and photographs, and cover several case studies, traditional practices, use of machines, soils and modification of soil characteristics, construction methods, binders and stabilizers, renderings and finishes with much sophistication. It is attached with bibliography, a list of organizations and new research in the field. It is indeed a comprehensive treatise on building with earth and an excellent textbook.

Now that this up–to–date manual on earth technology, imported from the West, is made available in India, it should give enough credibility to “earth” as a building material. The earth, not merely a matter but Mother Earth, is used by the majority of Indians to build a house.

It could now safely be recognized by and introduced in the organized sector of technical education of the architects, engineers and technicians/artisans by the Indian universities, IITs (Indian Institutes of Technology), ITIs (Industrial Training Institutes), polytechnics, boards of technical education at the state and national level, Council of Architecture, Indian Institute of Architects, Institute of Engineers, SSCE and HSCE Boards, Shramik Vidyapiths and other autonomous organizations engaged in housing, education and funding etc. besides NGOs (Non-Government Organizations) active in the rural and urban areas in development work.

Though earth as building material remained outside the educational curriculum in India, it was, however, given a due place in the famous “P.W.D. Handbook (1950, Rs. 7.62, First Edition 1876) of former Bombay Presidency during the British Rule.

There are other building materials, namely thatch and Bamboo, which are also ignored in the technical education in India. Thatch certainly has a place in the materials, specifications and practices in the West. Bamboo grows abundantly in India. It is absent in the western textbooks because it does not grow in that region.

What are the possibilities of applications of this treatise on earth in the Indian Context? Cities have their own constraints where earth to build upon and to build with is under great pressure. Nearly 50% population of Bombay (now Mumbai) lives in the slums and squatters. In these settlements, however, earth is a major component in spite of variety of rags being used. At the countryside the majority people continue to use earth in spite of urban influence to use high fossil energy consuming materials such as reinforced cement concrete (RCC).

The Indian countryside is full of diversity of land characteristics, climate, languages, food, dresses… which is beyond generalizations. It is obvious that soils and their characteristics change with localities. Various regions have their indigenous ways of using earth for building: plains of river Ganga, Jamuna, Brahmaputra etc. (flood-prone); desert areas of Gujarat – Rajasthan (scanty rain fall – now earthquake-prone); Deccan plateau (now earthquake-prone); tropical rain forest region of coast (cyclone-prone) and many other regions.

One must not expect to find all the answers to all the conditions in this book. The professionals, therefore, could trust a little more the traditions – the traditions of the so-called illiterates, uneducated, and ignorant rural folks, their wisdom and skills – and do not depend fully on such manuals while practicing at local levels.

Ironically folks from various parts of the country also could be found in the cities and towns after the massive migration that has been taking place during the last few decades. What is more? A major part of the labour force – unskilled, semi-skilled and skilled – in the building construction industry could be found in the slums and squatters, for example, in Bombay (now Mumbai).

As has been said earlier, the book has educative value as a textbook. Traditionally, however, science and technology were available free of cost to the people and learning has been experiential and holistic. It was not the department of education, but the people had autonomy in education. So also Epics and Puranas, which were passed on by mnemonic method from generation to generation over centuries and have become intrinsic part of life of people. When teaching became authoritative and totalitarian, Sant Jnaneshwar (saint-poet of Maharashtra state) had to ask a buffalo to recite Vedas to put the pundits in their right context. Sant Tukaram (saint-poet of Maharashtra state) challenged, “Only we understand meaning of Vedas; other carry burden on their heads.” We need to understand the mindset of the people. Today with printing technology and mass production, the education has gone into the safe custody of the privileged few and has become inaccessible to the ‘masses’.

The publisher’s note mentions that the book shall be available at 50% discount to the students of architecture and engineering. But the price is not mentioned – a popular gimmick. Taking into account the aids, supports and the price of the forest at the cost of people (not merely price of paper) the book should not cost more than Rupees 30/- to 40/- to make it truly global! Besides, the publicity given in the book to the commercially available machinery in the West should further bring down the price. Taking into account the huge demand for housing the price could be further slashed down to make it truly utilitarian book. Better still if the book is translated in the regional languages. All those who advocate sustainability, alternative – appropriate – intermediate etc. technologies should begin to apply energy costs rather than the currency costs while pricing any work – a book or a mud house.

We cannot, perhaps, ignore more than two hundred million people are living below poverty line, and as many are without shelter in India. In Indian sense, environmental concerns encompass matter, mind and Soul.

Traditional Mud Floor Technology


Traditional Mud Floors Technology

In India – a so called third world country – most people still continue to use mud as a conventional building material. It has en an important material in rural housing for millennia. The major part of rural house consists of mud plinth, floor, walls, plaster roof, roofing, silos, utensils, bed, seats, hearth etc. and the statues of deities, mud is either used as it comes or is used with other materials – stone, bamboo, Karavi (Strbilanthes callosus Nees) or as burnt bricks. Roofs in some places are made of a meter thick mud slabs (e.g. parts of Maharashtra, Karnataka, and Andhra etc.).
Mud is processed or treated with compounds such as cow dung, horse dung, ash, anthills, chopped straw of paddy or wheat, chopped organic fibres such as sisal or coir, lime or in baked form. Mud, as a building material, at one time was also compounded with extracts from plants, either to stabilise it or to make it waterproof: gum of banyan or papal trees, powder made from barks of Khair (Acacia catechu Wild) Arjuna (Terminalie Arjuna W.); tea made from three famous plants, known for their great medicinal value, known as Trifala (three fruits) Hirada (Terminalia Chebula Retz.), Behada (Terminalia Roxb.) and Amala (Embelic Mirobalan) besides many other materials such as iron powder for different uses.

The ancient forests, with advent of modern development, are now diminished and many species of trees have nearly vanished from the forests; Khiar, which is also useful for Tusser silkworms, for example, for making railway sleepers.

For centuries rural people have managed the construction of their houses with their own hands and with the resources available closed by. People with different trades, farmers, landless labourers, women, children… all participate in the construction of the house. Community Participation goes far beyond just to build a house – to build temples, mosques, bunds, roads, wells, in farming actions and many other community works. In modern India the governments and the elite of the First World India do not recognise this immense human energy.

The Community Participation also eliminates any need to employ commission agents such as contractors, public works departments, agencies, with government grants, engaged in construction of houses for the masses in rural areas.

Construction
The layer for the mud floor should be 12–15 cm thick. It should be spread over hard core of stone / rubble of 15 to 25 cm thickness. The hard core protects the floor from dampness rising from the ground, from rodents and to prevent it from deterioration due to underground settlement of the soil.

The mud selected should be fine grained, free from course sand or gravel, other organic or inorganic materials. The mud should be kept soaked in water for a week, thoroughly pulverised before spreading over the hard core.

The layer is then compacted by ramming with wooden tools. The floor must not dry quickly as it tends to develop cracks. Water should be sprinkled from time to time. This helps to keep moisture uniform throughout its depth. It should be compacted by ramming; once or twice a day for a week or till required finish is achieved. (While tamping the floor, water should b sprinkled lightly to avoid the mud sticking to the implements.)

With each course of tamping the floor becomes more and more impervious and homogeneous, smooth, hard and durable. With every temping, effort should be made to remove marks, and impressions of the instrument and unevenness of the surface. In the process meanwhile the floor goes on setting and slowly drying.

It is advisable to complete the whole floor without joints and without dividing it into panels. The joints or panels as used in cement concrete floors will cause deterioration in a mud floor.
Traditionally the surface is finished with cow dung wash. The floor thus prepared is suitable for many types of building except for industrial purposes. Contrary to popular opinion the mud floor is also suitable for high rainfall areas – even where it exceeds 3000 mm per year. Where floods occur often the mud floor gets damaged or remains damp for a long time.

Housing is not the end Product

A point to note is that in a traditional Indian house the mud floor does not end here. It goes beyond its construction: collection of appropriate materials, preparation, ramming, watering, tamping, levelling... The surface of the floor is finished with cow dung wash mixed with water applied by either hand or broom. This leaves a beautiful texture with a curvilinear pattern of dark grey-green shades. Cow dung wash is applied regularly once in a fortnight or two.

Daily dusting of floor sends back some quantity of loose particles to nature. The floor at the entrance is adorned with Rangoli (Marathi) or Alpana (Bengali); these are symbols such as Swastika painted / drawn with rice flour or pumis stone powder on floor, every morning by the women in the household. Similarly, during meals Rangoli is inscribed around the plate. These are not merely decorations; they are invocations to primal cosmic energy. In Indian culture Vastu – abode – is sacred; during construction from the foundation to the roof people carry ritual worships. Even biotic and abiotic nature is personified and worshiped.

In front of the entrance a Tulasi plant (Ocimum sanctum L.) placed on a platform where people lit oil or butter oil lamp every evening at dusk. Tulasi is considered holy; it is also medicinal plant as well as natural insecticide.
By Indian tradition, housing is not a finished product to buy in the commodity market of price inflation. It is a process of living with the house, not off the house, an association with environment of the house and homestead – an awareness of living organ.

Housing is a process of continuous maintenance, additions, alterations, attention through generations, and when one needs change, the elements used in the house either could be reused or sent back to the biomass – to the Earth.
