Countries that have experienced a delayed entry within the world economy have usually sustained an enhanced and faster globalisation process. This is the case for BRIC countries which are, compared to other emerging countries, organised on large economies and thus provide a stronger potential market. From this perspective, India appears to be the perfect case study with an economic growth expected to overcome China's growth in the near future. However, the "clichés" are persistent within a country mostly depicted as bipolar. On the one hand, it is considered as a new eldorado, the "Shining India", a place where multinationals aim to implement themselves due to the substantial increase of the consumer market. At the same time, India is also characterised by overcrowding, the major presence of slum areas and mass poverty, both in urban and rural areas. It is indeed possible that some areas will accommodate a bigger and bigger share of the growing middle class, while others will accentuate economic and social inequalities. Yet, can these extremes be truly representative of the diversity of such a large country? In fact, in some urban oriented spaces, the evolution of the tertiary sector is not strong enough to maintain a high level of employment while in rural spaces; an intensive farming model contributes to gradually reducing the number of labourers and landowners. As a result, the increase of the standard of living related to both economic and demographic growth is not homogeneously distributed over a territory where socio- economic divisions are already made worse by a tight caste system. With evidence dating back to 2400 BCE, it must be remembered that India is a country of old urbanisation. This has given rise to a rich and complex history and India is now home to a variety of languages, religions, castes, communities, tribes, traditions, urbanisation patterns and, more recently, globalisation-related dynamics. Perhaps no other country in the world seems to be characterised by such a great diversity. This begs the following questions: how is it possible to quantify and visualise the spatial gap of such a complex and subcontinent sized country? What are the main drivers affecting this spatial gap? It would indeed be simplistic to study India only through macro-economic indicators such as GDP. To deal with this complexity, a conceptualisation has been performed to strictly select 55 criteria that can affect the transformation sustained by the Indian territory in this age of enhanced globalisation. These selected factors have fed a multi-critera database characterised by aspects coming from economy, geography, sociology, culture etc. at the district scale level (640 spatial units) and on a ten-year timeframe (2001-2011). The assumption is as follows: each Indian district can be driven by different factors. The human capacity to understand a complex issue has been reached here since we cannot take into account and at the same time the behaviour of a large iv number of elements influencing one another. AI Based Algorithm methods (Bayesian and Neural Networks) have thus been resorted to as a good alternative to process a large number of factors. In order to be as accurate as possible and to keep a transversal point of view, the methodology is divided into a robust procedure including fieldwork steps. The results of the models show that the 55 factors interact, bringing the emergence of unobservable factors representative of broader concepts, which find consistency only in the case of India. It also shows that the Indian territory can be segmented into a multitude of subspaces. Some of these profiles are close to the caricatured India. However, in most cases, results show a heterogeneous country with subspaces possessing a logic of their own and far away from any cliché. Keywords: India, globalisation, urbanisation, middle classes, spatial segmentation, AI based- algorithms, Bayesian and Neural Networks, Self-Organizing Maps. vTable of Contents

INTRODUCTION
"Toutes les démarches du chercheur doivent pouvoir être explicitées, expliquées, justifiées, même quand il s'agit de l'intuition"1Mialaret Gaston (2004)
I was told by senior researchers in India that the first months of a thesis are always the less productive ones. According to them, India was a country so complex that a young researcher not familiar with it should get used to starting off in several wrong directions. Looking back, I can't but agree with them. Basically, when I arrived in India, I got stung by almost everything. I am not referring to the well-known cliché of a traveller setting foot in India and experiencing for the first time a little bit of culture shock and seeing chaos everywhere. Of course, it is difficult to go against some clichés (especially in large cities) such as traffic jam which is associated with constant sounds of horns, people everywhere riding rickshaws, motorcycles, trunks, bicycles, vendors of all kinds walking through the traffic, pollution, overcrowding, etc. Yet, I spent some time in Africa and South America studying the self-organised transportation systems when I was an undergraduate student. All in all, seeing order in chaos was what I have been trained for but yet, I could not have felt less prepared for "handling India" as something seemed indeed very different about this country. With the benefit of hindsight, I realise now that India is the very definition of a complex country. India is one of the most multi-faceted countries in the world and really is a mix of everything you can find around the world plus some specificities (such as the caste system). This country as it is today is the outcome of various civilisations that followed one another and is home now to a variety of languages, religions, castes, communities, tribes, traditions, etc., thereby increasing the degree of complexity of any topic you choose to address. During the first year of this research, I was indeed not aware of this complexity which is also reflected in the ways in which people interact. For example, there is a simple noncommittal nod that exists only in India and means neither "yes" nor "no". It is widely used for any topic of discussion and by all the strata of the population. You can for example order 11All actions of the researcher must be explicit, explained, justified, even when it comes to intuition.
2 some food in a restaurant and the waiter will give you that nod. What you must understand is that the waiter does not know if the food you just ordered is available in the kitchen and that he will check for you later. Most of the time, when you ask an Indian what are his thoughts about the caste system he will tell you that "castes" are now a thing of the past and that there are no more caste problems in India. One day, a new director had been appointed in an institute in which I worked. The new director was a foreigner and during the welcome drink, he decided to shake hands with all the staff. Unwittingly, the first person he shook hands with was a dalit2 of the cleaning staff. Immediately after that, all the other people backed off and refused the handshake since the hand was now "impure". It is only later that I realised that the people with whom you interact the most as a foreigner are people speaking English fluently and most of these people are from upper castes at the top of the social ladder. They are not fooling themselves when they state that there are no more caste problems in India. The Indian society is fragmented and most of the people live and work within their community and/or within their caste. For the groups at the top of the social ladder, the inequalities related to the caste system are not reflected at all in their day-to-day routine. To a Westerner, India turns out to be a country full of surprises on many occasions. I remember a friend of mine coming to my place in order to celebrate the fact that he was going to get married in the coming months. I congratulated him and asked how he met his bride. He gave me a strange look and told me that he hadn't met her yet and that he was waiting for his parents to introduce her to him. If arranged weddings are still common in India we should nonetheless be careful not to make any generalisation. You may wonder why I am starting with these stories instead of introducing the research topic. The answer is quite simple; I think that these events have deeply affected my work. Even if the first months of this research were less productive than those which followed; they were at the same time the most decisive ones. Indeed, it quickly became apparent that the first thing you learn about India is that you cannot fully understand how it works. Diversity is so great in India that any generalisation becomes irrelevant. I therefore thought that if India was so complex, the best way to address it was to adopt a holistic point ofquotesdbs_dbs27.pdfusesText_33[PDF] Bircher Kartoffeln - Klinik Hohenfreudenstadt
