This study is an exploration of land acquisition for Special Economic Zones (SEZs) in India. Land acquisition has become one of the most well known problems confronting the SEZ policy and other policies that encourage private investment in infrastructure. Land acquisition for SEZs has caused widespread popular mobilizations and resistance, which have in turn led to cost overruns, delays, and project failures. This study examines India's land acquisition framework, particularly the evolution of the Land Acquisition Act 1894, in order to understand the factors contributing to acquisition problems when the state uses its power of eminent domain, as well as when private developers attempt to acquire land through consensual market transactions. It uses two SEZs spanning over 14,000 hectares of land near Mumbai--Navi Mumbai SEZ and Mumbai SEZ--as cases through which to examine the land acquisition process.

The 1985 and 1986 Cotton Reports have the same publication and P-Series numbers.
An experiment was conducted to test the hypothesis that a nutritional stress (shortage of photosynthate) affects the hormonal balance in bolls and their abscission zones. It did. The concentration of indoleacetic acid (IAA) in abscission zones of young bolls decreased and boll shedding increased as competition for photosynthate increased. Water deficit also decreased the IAA content of young bolls and their abscission zones, but greatly increased the concentration of abscisic acid (ABA) a hormone that may increase boll shedding.

Landscape management is often referred to as a holistic concept, which deals with large-scale processes and multidisciplinary manners in regards to natural resource use with ecological and livelihood considerations. Seen in this light, landscape transformation should be understood within the context of the human-nature relationship, viewing human activities and their institutions as an essential part of the system rather than as external agents. When it comes to the landscape planning and management related to cotton farming in Gujarat, there has been diversity of interest groups such as local communities, governments, corporations and non-governmental organisations. In the present study, I examine two case studies of cotton production pertaining to the Gujarat region in order to study the opportunities and challenges faced by local farmers in the process of developing agriculture. In the first case study on Cotton Improvement Program in the nineteenth century, I highlight the socioecological consequences of the colonial cotton project and how it relates to the social dynamics of networks and agricultural landscape management. The second case study examines current debates regarding the social, economic and environmental impacts of genetically modified (GM) cotton on India’s social and natural landscape. This thesis emphasises that there are recursive motifs between the two case studies in terms of the local resistances, power relations and possible environmental effects, which can be explained through the state of ‘global core’ and ‘periphery’, and partly the framework of ecologically unequal exchange. The analysis of recurring patterns concludes that exploring the narratives of local experiences offers a number of significant details that show complex power dynamics manifested through constant struggles and resistances by ‘peripheral agent’.

This study aimed to examine farmers’ descriptions of their experiences of cultivating Bt cotton and to see whether or not the farmers’ descriptions of their experiences are in coherence with the purposes with Bt cotton. This was carried out through qualitative semi-structured interviews with Bt cotton farmers in Vidarbha, Maharashtra, and a qualitative content analysis of the farmers’ descriptions. Our conclusions are among other, that the experiences of the farmers are various. Some farmers have experienced what Bt cotton was aimed to lead to; higher yields and reduced use of pesticides while other farmers have experienced the opposite.

Les politiques à l'égard de l'habitat illégal jouent un rôle central dans l'effort de réduction de la pauvreté à l'échelle locale et nationale ; étant donné que la pauvreté devient de plus en plus un phénomène urbain. Cependant; la réduction de la pauvreté est rarement définie comme objectif principal des politiques des bidonvilles; mais est une conséquence indirecte de leur application. Cette thèse a comme objectif l'amélioration de la compréhension des effets des politiques à l'égard des bidonvilles sur le bien-être des ménages. Deux cas d'études sont abordés: le Schéma de Réhabilitation des Bidonvilles (SRB) à Mumbai (Inde) et les Projets Urbains Intégraux (PUI) à Medellin (Colombie). Entre autre; nous répondons aux questions suivantes : Quelles sont les causes de la mobilité résidentielle post-réhabilitation ? Quels sont les impacts de la SRB sur l'accès au crédit ? Quels sont les effets des projets de renouvellement urbain sur le niveau de consolidation des logements ? Nous utilisons des méthodologies récentes d'économie empirique permettant de comparer des groupes bénéficiaires des politiques à des groupes non-bénéficiaires. Dans le cas de Mumbai, une enquête a été réalisée par l'auteur auprès de 510 ménages dans 9 bidonvilles cibles de la politique SRB; celle-ci ayant été mise en place dans quatre d'entre eux. Dans le cas de Medellin trois sources d'information ont été utilisés (L'Enquête Qualité de Vie; l'Enquête Medellin Solidaria et l'Enquête SISBEN) permettant le suivi d'un ensemble de bénéficiaires et de non-bénéficiaires des politiques; avant et après les opérations de rénovation urbaine
Slum policies play an important role in poverty alleviation efforts at the local scale and at the national scale - as poverty becomes increasingly 'urban' phenomena. However, poverty reduction is rarely positioned as the main objective of slum policies and, when occurring, is an indirect result of their application. The purpose of this thesis is to provide a more complete understanding of how slum policies affect households' welfare. To explore these issues, two slum-upgrading interventions are used as case studies: the Slum Rehabilitation Scheme in Mumbai (India) and Urban Integral Projects in Medellin (Colombia). This research has addressed issues ranging from the causes of post-rehabilitation residential mobility to the impacts of slum rehabilitation on households' access to credit as well as the effects of Urban Renewal Projects on housing consolidation. We used recent evolution in empirical economics methodologies that allow comparing policy beneficiaries to non-beneficiaries. In the case of Mumbai a household's survey was carried out by the author in 9 slum pockets, 4 of which had already been rehabilitated and 5 to-be rehabilitated slums. In the case of Medellin household level information was obtained from three secondary sources (the Quality of Life Survey, the Medellin Solidaria Survey and the SISBEN Survey) that allowed following a set of beneficiaries and non-beneficiaries before and after Urban Renewal Projects took place

Cotton has over the past years become a less profitable crop to grow. This has affected millions of people cultivating it. In India the struggles of cotton farmers become clear when looking at the high suicide rates amongst them with economic reasons being the most common cause. In this thesis the aim is to investigate the situation of small cotton farmers in India and define the important factors in deciding their profitability. To be able to achieve this, a qualitative multiple case study in Maharashtra district, India was conducted with farmer interviews as the backbone of the study. Our contribution through this thesis is to provide an improved understanding of the cotton farmers’ situation and the factors that affect their yield. We found that for the farmers in this study insufficient access to water was the most pressing issue. Water is an important factor in deciding the yield of cotton and thus important for the farmers’ economy. This finding may not be representative for other cotton growing areas as the issues can vary greatly geographically.

The emergence of genetically modified organisms has sparked a multi-faceted debate, covering issues related to human health, ethics, and the environment. Discussions of the economics of GMO adoption are highly politicized and are influenced by large corporations and non-governmental organizations. This study aims to provide insight into the economic impacts of genetically modified organisms on individual farmers of cotton in India. The first GMO to reach commercialization in India was Bt cotton in 2002, which led to significant increases in revenue and yield among smallholder farmers. Using survey data collected between 2003 and 2009, I examine the economic impacts of Bt cotton and explore macro level changes in the Indian economy.

In 1991, India adopted neoliberalism, a system of political economic practices that promotes private property and free trade, as its political and economic system to promote development in their country. India's neoliberal reform has created issues surrounding human development, resource accumulation, and power struggles. Eleven years later, in 2002, Bt cotton was introduced to the Indian agricultural sector. This research examines how the genetically modified organism Bt cotton is being used to commodify nature in the context of agriculture under neoliberalism. The research focuses on the dispossession of the rural farmers through the commodification of agriculture using Bt cotton. Dispossession of the rural farmers happen through the implications that arise from the commodification of nature. Through Marxist theory of primitive accumulation, this research analyzes accumulation by dispossession and how it neglects the working class and its struggle in rural India. Through this examination, the research will argue alternatives to the dispossession of the working class and the commodification of nature through Bt cotton. Dispossession, in this research, is examined both through working class, but also through the dispossession of biodiversity. Through the loss of biodiversity, the rural farmers are becoming dispossessed from a more sustainable environment. Along with these goals, the research will also incorporate themes of food security through changing landscape of agriculture due to the incorporation of Bt cotton. This research argues the contradictions that are presented through the commodification of agriculture under neoliberalism and provide a contribution to social justice literature, and our understanding of the relationship between technology and the commodification of nature.

In 2005, the Government of India (GoI) introduced the Special Economic Zone (SEZ) Act, which changed the way India attracted foreign investors who wanted to utilize the country's natural and human capital. Considerable scholarly literature has examined why investment has been located in particular areas of India and described the factors that contribute to initiating economic growth. Yet the observation inspiring this research was that some states have operational SEZs, while other states with approved SEZ plans see investors retreat from their commitments. Why do some states have operational SEZs and other states do not? Focusing on the states of Maharashtra and Goa, this study explored information about the de-notification of zones in both states, leading to an examination of whether the factors that contributed to de-notification in Maharashtra were similar to those keeping Goa from having operational SEZs. I hypothesized that land acquisition practices, lack of physical infrastructure, and poor social infrastructure were key factors contributing to Maharashtra's de-notification and to Goa's struggle to create operational zones. The findings suggest that in order for SEZs to remain operational, comprehensive legislation must be put in place that addresses land rights, job training, and general education. Such a change would allow the residents in each state to participate more in the SEZ development scheme while mitigating India's endemic poverty.

According to several scientific reports, climate change will have an impact on water provision and thus agriculture, which depends on soil moisture for plant survival. India is a country that is heavily dependent on agriculture as a source of income. One of the country’s future challenges is securing water for irrigation. Cotton in India is an important cash crop which is grown under high evapotranspirative demand, using about 15% of the national water resources, making the crop vulnerable to changes in water availability.

The purpose of this study is to evaluate the resilience of cotton production with regards to water availability and pesticide use in Punjab and Andhra Pradesh. Three aspects of resilience: latitude, resistance and precariousness has been used to analyse three variables, precipitation, irrigation and pesticide in order to understand how these cotton growing systems are going to be affected by climate change. By bringing together existing data from several scientific reports and governmental websites, assumptions could be made whether these systems are resilient or if they are reaching a threshold. The results show that the cotton growing regions of Punjab are highly vulnerable when it comes to water provision in the region and that they might be reaching a threshold. Changes in climate are predicted to affect precipitation and temperature in the area, which in time might ultimately affect water resources in the region. Groundwater depletion and water logging are already prevailing problems in the area where almost all cotton production is irrigated. Cotton farmers in Andhra Pradesh are struggling with pest infestation which induces them to overconsume pesticides, affecting not only water quality in the area, but also farmers’ livelihood. It is likely that climate change will not minimize the outbreaks; on the contrary it might benefit some pests, which might increase the consumption of pesticide in the region. Coastal districts are more exposed to extreme weather which can harm cotton cultivation.

This thesis explores the extent to which Fairtrade (FT) might lead to a systemic shift in the way power relations are embedded and exercised in the international trading system. In doing so, it utilises power relations by positioning FT in the context of the world-systems theory, whilst arguing that FT’s ‘‘mainstreaming’’, top-down approach, principle implementation and scale have proven inadequate in modifying the international trading system. As such, by focusing on value chain ‘‘governance as power’’ (through its ‘‘buyer-driven’’ structure) and ‘‘governance as coordination’’, we highlight FT’s lack of systemic appreciation through its orientation towards only farming and consumer level by working solely with big brands. In parallel, we employ power analyses of some feminist authors in order to provide a bottom-up and horizontal dimension, which enables us to further advance the importance of FT’s farmer organisation and empowerment. As such, pursuing a qualitative approach, we use four FT GVCs as case studies: Two of them in Ghana-UK for cocoa-chocolate, in Kuapa Kokoo-Divine and Cocoa Life-Mondelez, and two in India-UK for cotton-apparel, in Chetna Organic-No Nasties and Agrocel-M&S. On this basis, our empirical findings aren’t favorable for FT’s contribution to systemic change. FT is used as a marketing tool by Mondelez and M&S, whilst leading to the dilution of FT principles and jeopardising FTI’s sustainability. FT has often proven irrelevant and ineffective due to strong government intervention, but also because of the market and governance structure advanced by TNCs. Thus, we argue that FT needs to consider going back to its fair trade roots and work with nation states instead of TNCs, whilst trying to replicate Kuapa Kokoo and Chetna as success cases, that went ‘‘beyond FT’’ through farmer ownership, forward integration, women empowerment and strong democratic processes, in order to achieve meaningful farmer empowerment and organisation in the long-run.

In recent times, special economic zones have become a popular mode of promoting economic development in developing countries. Through SEZs China has achieved immense economic growth, a model, which a number of developing countries are trying to emulate. India followed suite in establishing SEZs, however, it has not been able to achieve the same success as China. In this paper, I perform a comparitive analysis between India and China and study the impact on economic development. By highlighting the differences between the SEZs in the two countries I explain the reason for China's immediate success and India's slow growth. I finally conclude that SEZs are a viable method of achieving economic development, especially for developing countries.

Achieving sustainable production is a critical task in today’s globalised world. This is especially the case in the cotton garment industry where globally dispersed suppliers feed rapidly expanding demand across international markets. Practices associated with cotton garment production face numerous sustainability challenges from cotton farming to textile and garment manufacturing. Retailers are under increasing pressure to address these challenges and leading retailers are now actively trying to promote more sustainable production across all stages of production from raw material to final product. While numerous studies have investigated the relationship between retailers and their upper tier suppliers, there is little understanding of how sustainability challenges can be addressed across fragmented production processes. It is this gap that this thesis seeks to fill. Promoting sustainable production from raw materials to the final stages of manufacturing involves influencing practices of a diverse set of businesses responsible for different stages of production. This thesis defines the set of businesses that turn raw materials into final products as an ‘extended supplier network’ (ESN). Drawing on global value chain (GVC) and global production network (GPN) approaches to understanding how production is organised, the core question of this thesis is: To what extent is buyerdriven governance sufficient for promoting sustainable production across fragmented production processes in an ESN? GVC and GPN research provides insight into this issue as it offers a way to conceptualise how lead firms influence their suppliers. The GVC approach highlights the importance of lead buyers. The GPN approach incorporates this argument but further emphasises the importance of spatiality and the roles of a wider set of actors and processes. While both approaches theoretically incorporate all stages of production, garment industry studies using these approaches have tended to focus on relationships between brands and retailers and upper tier suppliers, paying insufficient attention to lower tiers. Considering the case of Indian cotton clothing production for major UK retailers, this study explores retailers’ governance relationships with producers at different points in their ESNs. Producers’ experiences of vertical governance through buyer-seller relationships across all stages of production within an ESN are explored. These producers’ experiences with horizontal governance within distinct local productive systems are also considered. Diverse producers’ locations within the ESN and within local productive systems are found to involve different governance experiences within the same ESN. Across the ESN, vertical governance flows are found to be limited by variation in potential for buyer governance across buyer-seller relationships in the multiple vertical pathways connecting retailers to raw material producers. Alternatively, retailers can connect to producers by making non-sourcing horizontal connections with actors in local productive systems. While dominant methods in retailers’ efforts at governance for sustainability have been vertical, horizontal connections are increasing across the industry. However, despite the emergence of new connections, this research finds that retailers’ influence over lower tier production processes remains limited. Empirically, this thesis provides insight into the complexity of sustainability challenges involved in the production of cotton garments. Conceptually, it shows the nature of diverse governance relationships across an ESN. It also emphasises that effective governance for sustainability cannot be achieved simply through vertical buyerdriven governance. Instead a more nuanced, and more complex, understanding of the interplay between vertical and horizontal is required, particularly considering the role of alliances. This has significant implications for policy, including the public and private governance for sustainability in the global cotton garment industry.

Agricultural fields are inherently variable across both space and time but are commonly managed uniformly. Uniform management can simultaneously lead to an under and over-application of resources (e.g. fertiliser) within the same field, resulting in poor resource efficiency and reduced profit margins. This research demonstrated the potential of publicly available datasets (i.e. remote sensing, digital soil maps, weather), machine learning techniques and crop models to inform management at a sub-paddock scale. These findings will help provide a cost-effective and efficient approach to improving farm productivity, profitability and sustainability in Australian irrigated cotton systems.

This thesis is divided into 2 parts. The first part (Chapters 1-5) concentrates on unravelling the . Precambrian geological history of the high-grade poly-metamorphic and poly-deformed basement of southernmost India, using field geology and U-Pb geochronology. Because Peninsular India occupied a central position in Gondwana, this work bears on reconstruction models of central Gondwana between circa 600 Ma and 200 :f1,a. The second part of the thesis (Chapter 6) tests the use of organic carbon isotopes as a chemostratigraphic tool to correlate between the lower part of terrestrial Gondwana (Upper Carboniferous to Triassic) sequences in India. This work contributes to (i) intra-basinal and inter-basinal stratigraphic correlation and carbon isotope variations during the Pennian-Triassic extinction event of Gondwana; and (ii) refines the inter-continental correlations of the Gondwana type sequences in India with those in South Africa and Madagascar. This century much attention has been focused on the reconstruction of Gondwana, and as a result, the broad relative positions of different Gondwana fragments and their later dispersal histories is now well understood. Finer-scale reconstructions, based on modern geochronological and isotope studies integrated with field studies of continental rocks, are still needed to resolve the detailed kinematic histories of continental break-up and the evolution of continental lithosphere in general. Shear zones that cross the boundaries of continental fragments provide 'piercing points' in fitting the fragments back together. To realize this, the kinematics and the timing of major shear zones need to be determined. The first part of this thesis, therefore, primarily focuses on understanding the kinematics and geochronology of a number of subvertical continental scale shear zones in the Southern Granulite Terrain of India (SGT).

The aim of this Bachelor thesis is to find keys to successful advocacy in a rural, Indian setting. The study is based on inductive, explorative research at a grassroots level, from a bottom-up perspective. Geographically, it takes place in the East Godavari District, in the state of Andhra Pradesh. At the centre of this study is the NGO:s Sujana and the Kadali Network, who are both advocating the rights of poor, marginalised and deprived people, as well as training people to carry out advocacy themselves. The theoretical framework for this thesis originates from theories within development communication, advocacy and Participatory Rural Appraisal. The research was carried out by making 16 individual interviews and 3 focus group interviews.  Findings from the interviews have been categorised into themes and analysed through meaning condensation. The result of this study shows that there are multiple ways in which grassroots movements in East Godavari conduct advocacy. The analysis states that advocacy can be successful in a short to medium time span; the most prominent keys to success being: having a driving spirit, being creative, developing networks and being knowledgeable about laws and rights. In a longer time span though, the advocacy and struggle for change is hampered by lack of, or conflicting, political interest from the local government and by conflicting economical interests from companies.

Every artifact in this consumerism world is connected to Earth’s four ecological layers. Everything around us, air, organism, water, and soil/rock also known by the names; atmosphere, biosphere, hydrosphere, and lithosphere. All together form the ecosphere, the place that contains all materials and resources that we use when creating artifacts.  »Every material that we use comes from the ecosphere and eventually goes back to it.« - Ann Thorpe The way humans use, extract, manufacture and dispose of materials has concerned me for many years, long before I started this design program. It has formed my way of making as a designer, and because of my love for textiles, I have been applying it in that field of practise. I want to design textiles that function and can be used frequently, with a purpose and in the end, decompose before I do. The aim of this conducted design project is to, in a playful way, break down the barrier between maker and user. Combined with unfolding the hidden truths about garments, how they are manufactured and where those textile components originate from. This would enable me to broaden my knowledge in the field and in return I will have the opportunity to share my insights with the public. Within this project I will also put the emphasis on the impact textiles have on our bodies, reproductive health and surrounding ecosystems.  Designing with the intention to highlight topics like this, the whole life cycle of garments, creates a stronger bond between user and maker. This is something I as a designer and maker want to build my foundation on.  In order to do this I needed to pin down where this conducted design project could take place and what sustainable possibilities of change it could embed for the future.

Our common future involves many important challenges. People and nature need to improve the relationship in order to reach an ecologically sustainable development. In a society where consumption of products steadily increases, the consumer awareness about social and environmental issues connected to the products becomes an importent factor. More and more companies choose to work more actively with these issues and more and more products get labelled by some of the eco labelling organisations. From the cradle to the gate means that a study has been done on a part of a products life cycle. In this master thesis a pair of cotton trousers has been followed from the cotton field and through the manufacturing chain in order to sees how much resource that are connected to the cultivation and to the production. Methological approach has been Life Cycle Inventory (LCI) according to ISO 14040. The empirical material is collected in South India, in an area known for its intense cotton manufacturing.

Studies like this can be a good way of showing the environmental impacts of a certain product. LCI can for example work as a criterion for eco labelling, but the methodology could also support the overall environmental work in companies.

Cette thèse s'intéresse à l'interaction des transactions dans le montage opérationnel de grands projets immobiliers et industriels. Depuis deux décennies à Chennai (capitale du Tamil Nadu, Inde), les pouvoirs publics font la promotion des Corridors de développement économique, qui transforment des hectares de terre, voire des villages entiers. Si les politiques publiques, la gestion des organisations ou les conflits qu'entraîne l'émergence de ces projets impliquant des acteurs multiples et exogènes sont étudiés, peu de travaux s'attachent à décomposer les mécanismes anticipés, les multiples formes de négociations et les contextes historiques dans lesquels s'inscrivent ces projets. En étudiant la rencontre de la localité avec le projet et les reconfigurations de la société locale qu'elle implique, nous changeons de perspective : nous donnons à voir comment les forces locales s'approprient ces vecteurs de croissance pour asseoir ou défendre leur position sociale. A travers l'étude ethnographique de villages, nous décrivons et renseignons les représentations associées au sol et les pratiques d'acquisition foncière afin d'éclairer les micro-logiques : ces processus fragiles et incertains dans lesquels les acteurs s'impliquent de façon coordonnée ou non. Cette approche soulève les paradoxes dans la concrétisation des projets, qui malgré leur planification, découlent tant de rapports de forces que de compromis. Elle rend également compte de la production d'innovations foncières qui articulent les normes juridiques, les jeux politiques, les croyances et appartenances sociales qui s'imposent
This thesis examines the interactions of transactions entailed in the process of setting up residential and industrial Mega-Projects. In Chennai (capital of Tamil Nadu, India), the regional government has been promoting Economic Development Corridors, which, for over two decades, have been transforming hectares of private agricultural lands, public lands and even entire villages. Although research on public policies, foreign private investment or land conflicts is well documented, little attention has been paid to the upstream mechanisms, the multiplicity of negotiations and the historical context in which those projects develop. By studying the interaction between villages and projects and the social and spatial local transformation taking place, this work presents a new perspective : how do local actors appropriate those vectors of growth to strengthen and defend their social position? Using ethnographic methodology, we describe and examine the meaning of land and land acquisition practices in order to bring to light the "micro-logics": fragile and uncertain processes in which actors implement non-linear and flexible strategies. This approach allows highlighting the paradoxes inherent in the process of project concretisation and which result from power relationships and compromises. In addition, it allows to unpack "land innovations processes" which emerge from legal norms, the interplay of political forces, beliefs and social roles

A growing number of companies realise that to achieve their environmental goals and satisfy stakeholder expectations, they need to look beyond their own facilities and to involve their suppliers in environmental initiatives. A life cycle approach means that the production system should be optimised as whole, across national boarders and individual organisations taking part all the way from extraction to disposal. This study is a Life Cycle Inventory of resources used when producing a piece of cotton garment and the method is based on the standardisation series of ISO 14040-43. The area of study, Tamil Nadu the most southern state of India, accounts for more than 90% of India’s knitwear exports to Western Europe. The main conclusion is that the Life Cycle Inventory could bean appropriate method to be used within the textile industry but the main advantage may not be in solving problems but instead framing them in a distinctive way and making people aware of them. An approach that combines life cycle and sustainability concepts could be a way towards enhanced corporate responsibility.

L'Inde est le deuxième producteur mondial de coton ; après la Chine, avec environ 12,1 millions d'hectares en 2011, soit le quart de la superficie cotonnière mondiale. Après l'avènement des biotechnologies agricoles, le gouvernement indien, sous l'égide du premier ministre Atal Bihari Vajpayee, a encouragé l'utilisation de coton génétiquement modifié, dénommé coton Bacillus thuringiensis (Bt). Les variétés de coton Bt permettent de lutter contre les pertes de rendement causées par les parasites lépidoptères. Toutefois, leur implantation n'a pas été sans difficulté (la résistance des insectes, la pollution des sols, l'utilisation massive d'eau et d'engrais, le déséquilibre de l'écosystème et l'appauvrissement des fermiers). Aujourd'hui, l'Inde connaît un débat majeur autour de son expérience en matière d'adoption de coton transgénique, débat où plusieurs arguments d'impacts sur le bien-être des petits agriculteurs sont avancés. Depuis sa commercialisation en 2002, le coton Bt a provoqué les mécontentements et les suicides des fermiers appauvris. En moyenne un paysan se donne la mort toutes les 30 minutes. Les victimes sont principalement les petits fermiers qui cultivaient les semences génétiquement modifiés dans les Etats indiens : Andhra Pradesh, Karnataka, Madhya Pradesh et Maharashtra. Ces agriculteurs étaient pour la plupart endettés auprès de la compagnie semencière Mahyco-Monsanto Biotech (MMB), qui leur fournissait à crédit les semences Bt ainsi que les pesticides. Faut-il y déceler une corrélation entre le coton génétiquement modifié et ces suicides atypiques ? Ainsi, l'objectif de cette thèse est d'explorer, tant sur le plan théorique qu'empirique, la relation entre l'utilisation du coton Bt et le suicide des agriculteurs en Inde...

Over 250,000 farmers have committed suicide across India since 1995, the majority of deaths concentrated in central India’s cotton belt. Scholarly consensus views suicides amongst the peasantry as debt-induced: transgenic cotton cultivation imprisons producers in downward monetary debt spirals. Based on two years of fieldwork in rural Vidarbha, my dissertation, ‘The Life of Debt in Rural India,’ examines the proximate entanglements of debt and techno-material transformations in cotton cultivation. It demonstrates that with the emergence of cash-debt as an essential component of the productive process, differentiated interest rates have become the medium of negotiating social and familial proximity. From a formerly caste-specific proscribed activity, the generalization of usurious lending has made monetary debt the language of social prestations (of gifts, grain and labour), reshaping customary understandings of status, honour and obligation. This project contributes to the anthropology of South-Asia, the peasantry and debt in two ways. In ethnographically tracing the force of debt as social obligation and the imbrication of modes of production with symbolic cultural life, I demonstrate the inadequacy of an economistic obsession with debt as monetary liability. Accordingly, against characterizations of the ‘risk-averse’ peasant in a customary moral economy, I describe an emergent ethical economy centered on uncertainty as risk becomes a structural precondition of peasant life.

abstract: The collision between the Indian and Eurasian tectonic plates marked the onset of the rise of the Himalayan-Tibetan orogen, but also brought about profound changes to the Earth's oceans and climate. The exact sequence of events that occurred during this collision is poorly understood, leading to a wide range of estimates of its age. The Indus and Yarlung sutures are generally considered to represent the final collision between India and Eurasia, and together form a mostly continuous belt that can be traced over 2000 km along strike. In the western portions of the orogen the Karakoram Fault introduces a key complexity to the study of timing of collision by offsetting the Indus and Yarlung sutures. Recent work has used the complexities introduced by the Karakoram Fault to suggest that the more northerly Shyok suture, not the Indus suture, represents the India-Eurasia collision zone. Estimates for timing of the India-Eurasia collision fall into one of three groups: 40-34 Ma, 55-50 Ma, and 66-60 Ma. Attempts to reconcile these models have thus far been unsuccessful. In order to provide additional data that might further clarify the timing and location of collision, studies have been performed along the Shyok suture in India and along the Yarlung suture in Tibet at Sangsang. A study along the Shyok suture argues that the suture formed between 92-85 Ma. This timing precludes an interpretation that the Shyok suture marks the location of the India-Eurasia collision. A second study demonstrates the utility of two new geochronometers, (U-Th)/Pb joaquinite and 40Ar/39Ar neptunite, that play an important role in unraveling the tectonic history of the Yarlung suture. A third study is an investigation of the structure and geochronology of the Sangsang ophiolite complex. Here, multiple (U-Th)/Pb and 40Ar/39Ar systems record magmatism and metamorphism spanning ca. 125-52 Ma. By tying these chronometers to tectonic process, a history is reconstructed of the southern margin of Tibet that includes Early Cretaceous to Late Cretaceous forearc rifting associated with mid ocean ridge subduction, Paleocene accretionary wedge uplift and erosion, and finally Eocene metasomatism and collision.

The utilization of Geographic Information System (GIS) offers a wide range of applications for groundwater assessment, delineation, discovery, and resource management. The aim of the present study is to establish a long-term plan for groundwater consumption by implementing novel approaches that ensure the proper utilization and effective maintenance of critical groundwater resources. In this study, GIS techniques, employing Satty's analytical hierarchy method (AHP), were used to demarcate groundwater potential zones in the National Capital Territory (NCT) of India. Seven spatial and non-spatial thematic layers, including Slope, Geology, Rainfall, Soil, Land use / Land cover, Soil, Lineament, and Drainage Density, were examined in the GIS software, and appropriate weights were assigned to define the Groundwater potential zones. An integrated map for Delhi, India was generated as a result. The groundwater potential areas were categorized into five zones: 1-very poor, 2-poor, 3-moderate, 4-good, and 5- very good. The very poor class covered an area of 12.87 km2, poor class covered 174.24 km2, moderate class covered 695.58 km2, good class covered 592.61 km2, and very good class covered 23.08 km2, respectively. This study helps in effective resource management, water supply planning, agricultural development, environmental protection, and disaster management. By understanding the distribution and availability of groundwater, stakeholders can make informed decisions to ensure sustainable use and protection of this valuable resource.

This thesis looks at the divergent policy decisions on the commercial release of two genetically modified (GM) crops in India. Bt cotton was introduced in India in 2002, and has spread widely across the country, though not without controversy. In 2010, the first GM food crop – Bt Brinjal (eggplant) – was put forward for approval. In contrast to the Bt cotton decision, and following heated debate and a series of public consultations across the country, an indefinite moratorium was placed on the crop. In this thesis, I unpack the various factors that shaped both decisions and the politics that accompanied them. To facilitate this analysis, I use a conceptual framework that combines four key forces that are often the focus of food governance analysis, but which are not always considered together. I argue that the divergence in outcomes can be explained by a confluence of shifts in key elements of the policy process. These dimensions of influence can be understood in four related categories: corporate actors, institutional mechanisms, science and science networks, and discursive elements. Changes that took place in each of these dimensions in the period between the two decisions align to explain divergent outcomes that no individual influence could. The conceptual framework I develop in this thesis presents a useful structure to analyse the often-complex and multi-causal processes and outcomes related to food and environmental issues. The results of this research have implications for the future direction of agricultural GMO policy in India, as well as in other countries in the global South.

Planet earth is restless and one cannot control its inside activities and vibrations those leading to natural hazards. Earthquake is one of such natural hazards that have affected the mankind most. Most of the causalities due to earthquakes happened not because of earthquakes as such, but because of poorly designed structures which could not withstand the earthquake forces. The improper building construction techniques adopted and the high population density are the major causes of the heavy damage due to earthquakes. The damage due to earthquakes can be reduced by following proper construction techniques, taking into consideration of appropriate forces on the structure that can be caused due to future earthquakes. The steps towards seismic hazard evaluation are very essential to estimate an optimal and reliable value of possible earthquake ground motion during a specific time period. These predicted values can be an input to assess the seismic vulnerability of an area based on which new construction and the restoration works of existing structures can be carried out. A large number of devastating earthquakes have occurred in India in the past. The northern region of India, which is along the plate boundary of the Indian plate with the Eurasian plate, is seismically very active. The north eastern movement of Indian plate has caused deformation in the Himalayan region, Tibet and the North Eastern India. Along the Himalayan belt, the Indian and Eurasian plates converge at the rate of about 50 mm/year (Bilham 2004; Jade 2004). The North East Indian (NEI) region is known as one of the most seismically active regions in the world. However the peninsular India, which is far away from the plate boundary, is a stable continental region, which is considered to be of moderate seismic activity. Even though, the activity is considered to be moderate in the Peninsular India, world’s deadliest earthquake occurred in this region (Bhuj earthquake 2001). The rapid drifting of Indian plate towards Himalayas in the north east direction with a high velocity along with its low plate thickness might be the cause of high seismicity of the Indian region. Bureau of Indian Standard has published a seismic zonation map in 1962 and revised it in 1966, 1970, 1984 and 2002. The latest version of the seismic zoning map of India assigns four levels of seismicity for the entire Country in terms of different zone factors. The main drawback of the seismic zonation code of India (BIS-1893, 2002) is that, it is based on the past seismic activity and not based on a scientific seismic hazard analysis. Several seismic hazard studies, which were taken up in the recent years, have shown that the hazard values given by BIS-1893 (2002) need to be revised (Raghu Kanth and Iyengar 2006; Vipin et al. 2009; Mahajan et al. 2009 etc.). These facts necessitate a comprehensive study for evaluating the seismic hazard of India and development of a seismic zonation map of India based on the Peak Ground Acceleration (PGA) values. The objective of this thesis is to estimate the seismic hazard of entire India using updated seismicity data based on the latest and different methodologies. The major outcomes of the thesis can be summarized as follows. An updated earthquake catalog that is uniform in moment magnitude, has been prepared for India and adjoining areas for the period till 2010. Region specific magnitude scaling relations have been established for the study region, which facilitated the generation of a homogenous earthquake catalog. By carefully converting the original magnitudes to unified MW magnitudes, we have removed a major obstacle for consistent assessment of seismic hazards in India. The earthquake catalog was declustered to remove the aftershocks and foreshocks. Out of 203448 events in the raw catalog, 75.3% were found to be dependent events and remaining 50317 events were identified as main shocks of which 27146 events were of MW ≥ 4. The completeness analysis of the catalog was carried out to estimate completeness periods of different magnitude ranges. The earthquake catalog containing the details of the earthquake events until 2010 is uploaded in the website the catalog was carried out to estimate completeness periods of different magnitude ranges. The earthquake catalog containing the details of the earthquake events until 2010 is uploaded in the website the catalog was carried out to estimate completeness periods of different magnitude ranges. The earthquake catalog containing the details of the earthquake events until 2010 is uploaded in the website A quantitative study of the spatial distribution of the seismicity rate across India and its vicinity has been performed. The lower b values obtained in shield regions imply that the energy released in these regions is mostly from large magnitude events. The b value of northeast India and Andaman Nicobar region is around unity which implies that the energy released is compatible for both smaller and larger events. The effect of aftershocks in the seismicity parameters was also studied. Maximum likelihood estimations of the b value from the raw and declustered earthquake catalogs show significant changes leading to a larger proportion of low magnitude events as foreshocks and aftershocks. The inclusions of dependent events in the catalog affect the relative abundance of low and high magnitude earthquakes. Thus, greater inclusion of dependent events leads to higher b values and higher activity rate. Hence, the seismicity parameters obtained from the declustered catalog is valid as they tend to follow a Poisson distribution. Mmax does not significantly change, since it depends on the largest observed magnitude rather than the inclusion of dependent events (foreshocks and aftershocks). The spatial variation of the seismicity parameters can be used as a base to identify regions of similar characteristics and to delineate regional seismic source zones. Further, Regions of similar seismicity characteristics were identified based on fault alignment, earthquake event distribution and spatial variation of seismicity parameters. 104 regional seismic source zones were delineated which are inevitable input to seismic hazard analysis. Separate subsets of the catalog were created for each of these zones and seismicity analysis was done for each zone after estimating the cutoff magnitude. The frequency magnitude distribution plots of all the source zones can be found at http://civil.iisc.ernet.in/~sitharam . There is considerable variation in seismicity parameters and magnitude of completeness across the study area. The b values for various regions vary from a lower value of 0.5 to a higher value of 1.5. The a value for different zones vary from a lower value of 2 to a higher value of 10. The analysis of seismicity parameters shows that there is considerable difference in the earthquake recurrence rate and Mmax in India. The coordinates of these source zones and the seismicity parameters a, b & Mmax estimated can be directly input into the Probabilistic seismic hazard analysis. The seismic hazard evaluation of the Indian landmass based on a state-of-the art Probabilistic Seismic Hazard Analysis (PSHA) study has been performed using the classical Cornell–McGuire approach with different source models and attenuation relations. The most recent knowledge of seismic activity in the region has been used to evaluate the hazard incorporating uncertainty associated with different modeling parameters as well as spatial and temporal uncertainties. The PSHA has been performed with currently available data and their best possible scientific interpretation using an appropriate instrument such as the logic tree to explicitly account for epistemic uncertainty by considering alternative models (source models, maximum magnitude in hazard computations, and ground-motion attenuation relationships). The hazard maps have been produced for horizontal ground motion at bedrock level (Shear wave velocity ≥ 3.6 km/s) and compared with the earlier studies like Bhatia et al., 1999 (India and adjoining areas); Seeber et al, 1999 (Maharashtra state); Jaiswal and Sinha, 2007 (Peninsular India); Sitharam and Vipin, 2011 (South India); Menon et al., 2010 (Tamilnadu). It was observed that the seismic hazard is moderate in Peninsular shield (except the Kutch region of Gujarat), but the hazard in the North and Northeast India and Andaman-Nicobar region is very high. The ground motion predicted from the present study will not only give hazard values for design of structures, but also will help in deciding the locations of important structures such as nuclear power plants. The evaluation of surface level PGA values is of very high importance in the engineering design. The surface level PGA values were evaluated for the entire study area for four NEHRP site classes using appropriate amplification factors. If the site class at any location in the study area is known, then the ground level PGA values can be obtained from the respective map. In the absence of VS30 values, the site classes can be identified based on local geological conditions. Thus this method provides a simplified methodology for evaluating the surface level PGA values. The evaluation of PGA values for different site classes were evaluated based on the PGA values obtained from the DSHA and PSHA. This thesis also presents VS30 characterization of entire country based on the topographic gradient using existing correlations. Further, surface level PGA contour map was developed based on the same. Liquefaction is the conversion of formally stable cohesionless soils to a fluid mass, due to increase in pore pressure and is prominent in areas that have groundwater near the surface and sandy soil. Soil liquefaction has been observed during the earthquakes because of the sudden dynamic earthquake load, which in turn increases the pore pressure. The evaluation of liquefaction potential involves evaluation of earthquake loading and evaluation of soil resistance to liquefaction. In the present work, the spatial variation of the SPT value required to prevent liquefaction has been estimated using a probabilistic methodology, for entire India. To summarize, the major contribution of this thesis are the development of region specific magnitude correlations suitable for Indian subcontinent and an updated homogeneous earthquake catalog for India that is uniform in moment magnitude scale. The delineation and characterization of regional seismic source zones for a vast country like India is a unique contribution, which requires reasonable observation and engineering judgement. Considering complex seismotectonic set up of the country, the present work employed numerous methodologies (DSHA and PSHA) in analyzing the seismic hazard using appropriate instrument such as the logic tree to explicitly account for epistemic uncertainties considering alternative models (For Source model, Mmax estimation and Ground motion prediction equations) to estimate the PGA value at bedrock level. Further, VS30 characterization of India was done based on the topographic gradient, as a first level approach, which facilitated the development of surface level PGA map for entire country using appropriate amplification factors. Above factors make the present work very unique and comprehensive touching various aspects of seismic hazard. It is hoped that the methodology and outcomes presented in this thesis will be beneficial to practicing engineers and researchers working in the area of seismology and geotechnical engineering in particular and to the society as a whole.

The north eastern movement of Indian plate has caused deformation in the Himalayan region, Tibet and the North Eastern India. Along the Himalayan belt, the Indian and Eurasian plates converge at the rate of about 50 mm/year (Bilham 2004; Jade 2004). The North East Indian (NEI) region is known as one of the most seismically active regions in the world. However the peninsular India, which is far away from the plate boundary, is a stable continental region, which is considered to be of moderate seismic activity. Even though, the activity is considered to be moderate in the Peninsular India, world’s deadliest earthquake occurred in this region (Bhuj earthquake 2001). The rapid drifting of Indian plate towards Himalayas in the north east direction with a high velocity along with its low plate thickness might be the cause of high seismicity of the Indian region.

In den 1980er Jahren begannen viele Entwicklungsländer, ihre Saatgutmärkte zu liberalisieren. In der Folge verbreitete sich die Nutzung proprietärer Saatguttechnologien, einschließlich gentechnisch veränderter Pflanzen (GV-Pflanzen). Die Konsequenzen dieser Entwicklung für Kleinbauern werden seither kontrovers diskutiert. Kritiker befürchten, dass Privatisierung die Qualität von Saatgut sowie den kleinbäuerlichen Zugang zu ihm verschlechtert. Befürworter gehen davon aus, dass proprietäres Saatgut landwirtschaftliche Produktivität und Einkommen steigern kann. In dieser Dissertation untersuchen wir Auswirkungen proprietärer Saatguttechnologien auf Kleinbauern. Bacillus thuringiensis-Baumwolle (Bt-Baumwolle) in Indien und Hybridmais in Tansania. Der dritte Fokus dieser Arbeit liegt auf der Adoption proprietärer Saatguttechnologien, wo erneut auf Hybridmais in Tansania Bezug genommen wird. Infolge einer ausländischen Investition transferierte eine indische Saatgutfirma Mitte der 1990er Jahre die Bt-Technologie in mehrere Baumwollhybriden. Diese Hybriden wurden 2002 zum Anbau zugelassen. In den Folgejahren verwendeten auch zahlreiche andere Saatgutfirmen die Bt-Technologie in ihren Züchtungsprogrammen. 2011 bauten 7 Millionen Bauern auf etwa 90% der indischen Baumwollfläche Bt-Baumwolle an. Sie ist gegen Kapselbohrer, eine Gruppe wichtiger Schädlingsinsekten, resistent. Dadurch kann sie den Einsatz von Insektiziden verringern und außerdem den effektiven Ertrag erhöhen. Dies würde Kosteneinsparungen bei Pestiziden und höhere Erlöse nach sich ziehen, welche wiederum das landwirtschaftliche Einkommen steigern können. Wenn aber die Saatgutpreise von Bt-Baumwolle hoch und die Ertragseffekte klein sind, könnte der Einkommenseffekt gering oder negativ ausfallen. Zu den Auswirkungen von Bt-Baumwolle wurden viele Studien publiziert, aber Selektionsverzerrungen, die Entwicklungsdynamik der Effekte und über Einzelfelder hinausgehende Wirkungen wurden bisher nicht ausreichend berücksichtigt. Hier analysieren wir Paneldaten aus dem Zeitraum 2002-2008. Mithilfe von Fixed-Effects-Modellen reduzieren wir Selektionsverzerrungen und betrachten den zeitlichen Verlauf der Effekte. Unsere Schätzergebnisse zeigen, dass Bt im Zeitraum 2002-2008 den Ertrag um 24% und den Deckungsbeitrag um 50% erhöhte, sowie den Lebensstandard im Zeitraum 2006-2008 um 18%. Außerdem finden wir Hinweise für eine Steigerung der Ertrag- und Deckungsbeitragseffekte über den gesamten Zeitraum. Einen Rückgang des Insektizideinsatzes in Bt- und konventionellen Feldern, der wahrscheinlich ein Zeichen für eine starke Dezimierung von Kapselbohrern durch die Zunahme des Bt-Anbaus ist, können wir ebenfalls beobachten. Nach der Liberalisierung des Saatgutmarkts in Tansania Anfang der 1990er Jahre begannen mehrere private Saatgutfirmen mit dem Vertrieb von Hybridmais. Hybriden können zu einem Ertragszuwachs führen, der wiederum Erlös und Einkommen steigern kann. Auf der anderen Seite könnte der Einkommenseffekt negativ ausfallen, wenn Hybridsaatgut teurer als Nichthybridsaatgut ist. Zudem kann ein leistungsstarker Nichthybride durchaus auch einen höheren Ertrag erzielen als mancher Hybride. Es gibt zwar Studien, die Produktivitätseffekte von Hybridmais in Afrika evaluieren, aber in der Regel kontrollieren sie nicht Störfaktoren, wie etwa Bodenqualität oder Düngereinsatz. Darüber hinaus liegen kaum Untersuchungen zu modernen Maissorten in Afrika vor, die neben der Produktivität auch Effekte auf den Lebensstandard landwirtschaftlicher Haushalte berücksichtigen. Wir analysieren einen Querschnittsdatensatz aus dem Norden und Osten des Landes und finden einen Ertragszuwachs von 50-60% durch Hybriden. Dieser führt auch zu einem höheren Deckungsbeitrag. Die Zugewinne treten vor allem im Norden auf, wo sie außerdem den Lebensstandard um 15% erhöhen. Im Osten bringen Hybriden keine Vorteile hinsichtlich Ertrag, Deckungsbeitrag oder Lebensstandard. Da sich jedoch die Mehrheit der Anwender im Norden befindet, profitieren in einer überregionalen Betrachtung die meisten Hybridnutzer von der Technologie. Außerdem finden wir heraus, dass der Ertragseffekt von Hybriden unabhängig vom Einsatz von Mineraldünger, Bewässerung, Pestiziden oder Mischanbau ist. Allerdings ist die Adoptionsrate von Hybridmais in Tansania gering. Ein möglicher Grund könnte darin liegen, dass seine Verwendung durch bestimmte Faktoren, wie etwa einen mangelnden Informationstand der Bauern bezüglich der Hybriden, erschwert ist. In unserer Stichprobe bauen 31% der Bauern Hybridmais an. Im Norden sind Hybriden den meisten Bauern bekannt und 49% verwenden die Technologie, während im Osten nur 50% von der Technologie gehört haben und nur 12% sie nutzen. Mithilfe des Average Treatment Effect Framework errechnen wir, dass eine Informierung aller Bauern über Hybriden die Adoptionsrate auf 45% ansteigen lassen würde. Jedoch wären dann die meisten neuen Anwender im Osten, wo die Ertrags- und Deckungsbeitragseffekte von Hybriden klein sind. Im Norden, wo die Adoption einträglicher ist, haben bereits fast alle Bauern von Hybriden gehört. Außerdem zeigt sich, dass eine Verbreitung von Informationen über Hybriden durch Beratung und ländliche Netzwerke im Norden (nicht im Osten) stattfindet und daher als Resultat der dort höheren Nützlichkeit verstanden werden kann. Für diese Interpretation spricht auch, dass wir keine Hinweise finden, dass Risiko oder Mangel an Kreditzugang die Adoption verhindern. Daher erscheint es wahrscheinlich, dass Informationsflüsse und Adoptionsentscheidungen primär vom Nutzen, den Hybriden gegenüber Nichthybriden bieten, bestimmt werden. Wir kommen zu dem Schluss, dass der Privatsektor verbesserte Saatguttechnologien für Kleinbauern in Entwicklungsländern liefern kann und dass derartige Saatguttechnologien einschließlich GV-Pflanzen diesen Kleinbauern dienlich sein können. Daher sollte die Liberalisierung von Saatgutmärkten in Entwicklungsländern unterstützt werden. Außerdem müssen Regulierungen, welche die Verfügbarkeit von Saatguttechnologien einschränken, den möglichen Nutzen dieser Technologien für Landwirte berücksichtigen. Und schließlich sollten Politik und Geberorganisationen in ihren Förderentscheidungen die Beseitigung von Adoptionshemmnissen gegen die Schaffung verbesserter Technologien abwägen.

The main objective of my dissertation is to analyze and compare the socio-ecological implications of the adoption of genetically modified (GM) seeds and alternative agroecological farming methods for farming communities in Alberta, Canada and Andhra Pradesh, India localities situated in contrasting geopolitical, socio-cultural, and structural-institutional contexts in the global economy. For this research, the adoption of GM canola in Alberta and GM cotton in Andhra Pradesh are used as comparative case studies to explore the qualitative impact of agricultural biotechnology on farming communities. Many studies have examined the potential impact of GM crops, but few have looked beyond economic cost-benefit analysis. In this dissertation, I examine social and cultural aspects of farmer decision-making in the adoption of the new seed technology, farmer receptivity to new cropping methods, knowledge translation between laboratory and farmer, and the impact of global knowledge-based technology on local knowledge systems, socio-cultural practices, the nature-society relationship, and gender relations. I use a global ethnography methodology and draw on a series of field interviews with farmers to provide sociological insight into how global processes of the Gene Revolution impact different farming communities in different localities in the world-economy. In this dissertation I argue that the debate about the new agricultural technologies (e.g. GM seeds), the environment and agrarian crises should not be narrowed to the question of new technologies per se. Rather it should be understood from an agrarian political ecology perspective articulating political economy (neoliberal governance at global, national and provincial levels, and the processes of dispossession of primary agricultural producers from their means and conditions of production), socio-cultural systems (the construction of hegemonic discourse about genetically modified organisms, agricultural deskilling, gender relations), and ecosystems (a process of mastering nature, monoculturization, environmental risks, metabolic rift) in the context of neoliberal globalization. My fieldwork study of the Gene Revolution provides closer, more fine-grained research and analysis of its impacts with sensitivity to local class and status, gender and cultural issues, and the ways in which farmers technology adoption decisions can dramatically alter overall quality of life, local knowledge systems, community development, the sustainability of agriculture and the ecosystem itself.

Tee present research focuses on seismic hazard studies for the states of Tripura and Mizoram in the North-East India with taking into account the complex sesismotectonic characteristics of the region. This area is more prone to earthquake hazard due to complex subsurface geology, peculiar topographical distribution, continuous crustal deformation due to the under thrusting of Indian and the Eurasian plates, a possible seismic gap, and many active intraplate sources identified within this region. The study area encompasses major seismic source zones such as Indo Burmese Range (IBR), Shillong Plateau (SP), Eastern Himalayan arc (EH), Bengal Basin (BB), Mishmi Thrust (MT) and Naga Thrust (NT). Five historical earthquakes of magnitude Mw>8 have been listed in the study area and 15 events of magnitude Mw>7 have occurred in last 100 years. Indian seismic code BIS-1893-2002 places the study area with a high level of seismic hazard in the country (i.e. seismic zone V). More than 60% of the area is hilly steep-terrain in nature and the altitude varies from 0 to 3000 meters. Recent works have located a seismic gap, known as the Assam gap since 1950 between the EH, SP, and IBR with the Eurasian plate. Various researchers have estimated the return period, and a large size earthquake is expected in this region any time in future. The area is also highly prone to liquefaction, since rivers in Tripura (Gomati, Howrah, Dhalai, Manu, Bijay, Jeri, Feni) and the rivers in Mizoram (Chhimtuipui, Tlawng, Tut, Tuirial and Tuivawl etc.) are scattered throughout the study area where soil deposits are of sedimentary type. In 2011, both the states together have experienced 37 earthquakes (including foreshocks and aftershocks) with magnitudes ranging from 2.9 to 6.9. Of these events, there were 23 earthquakes (M>4) of magnitudes M6.4 (Feb 4th 2011), M6.7 (March 24th 2011), M6.9 (Sept.18th 2011), M6.4 (October 30th 2011), M6.9 (Dec 13th 2011), M5.8 (Nov 21st 2011), M5 (Aug 18th 2011), M4.9 (July 28th 2011), M4.6 (Dec 15th 2011), M4.6 (Jan 21st 2011), M4.5 (Dec 9th 2011), M4.5 (Oct 21th 2011), M4.5 (Oct 17th 2011), M4.5 (Sept 18th 2011), M4.3 (Oct 10th 2011), M4.3 (Sept 22nd 2011), M4.3 (April 4th 2011), M4.2 (Sept 9th 2011), M4.2 (Sept 18th 2011), M4.1 (April 29th 2011), M4.1 (Feb 22nd 2011), M4 (June 9th 2011), and M4 (Dec 2nd 2011) which occurred within this region [source: IMD (Indian Metrological Department), India]. The earthquake (M6.9) that occurred on Sept. 18th 2011 is known as the Sikkim earthquake, and it caused immense destruction including building collapse, landslides, causalities, disrupted connectivity by road damages and other infrastructural damages in Sikkim state as well as the entire North-East India. In the cities of Agartala and Aizawl of Tripura and Mizoram, construction of high rise building is highly restricted by the Government. Being the capital city, many modern infrastructures are still pending for growth of the city planning. Although many researchers have studied and reported about the status of seismicity in North-East Region of India, very few detailed studies have been carried out in this region except Guwahati, Sikkim and Manipur where almost the whole of the study area is highly vulnerable to severe shaking, amplification, liquefaction, and landslide. From the available literature, no specific study exists for Tripura and Mizoram till date. In the present research, seismic hazard assessment has been performed based on spatial-temporal distribution of seismicity and fault rupture characteristics of the region. The seismic events were collected from regions covering about 500 km from the political boundary of the study area. The earthquake data were collected from various national and international seismological agencies such as the IMD, Geological Survey of India (GSI), United State Geological Survey (USGS), and International Seismological Centre (ISC) etc. As the collected events were in different magnitude scales, all the events were homogenized to a unified moment magnitude scale using recent magnitude conversion relations (region specific) developed by the authors for North-East Region of India. The dependent events (foreshocks and aftershocks) were removed using declustering algorithm and in total 3251 declustered events (main shocks) were identified in the study area since 1731 to 2011. The data set contains 825 events of MW < 4, 1279 events of MW from 4 to 4.9, 996 events MW from 5 to 5.9, 131 events MW from 6 to 6.9, 15 events MW from 7 to 7.9 and 5 events MW ≥8. The statistical analysis was carried out for data completeness (Stepp, 1972). The whole region was divided into six seismic source zones based on the updated seismicity characteristics, fault rupture mechanism, size of earthquake magnitude and the epicentral depth. Separate catalogs were used for each zone, and seismicity parameters a and b were estimated for each source zone and other necessary parameters such as mean magnitude (Mmean), Mmax, Mmin, Mc and recurrence periods were also estimated. Toposheets/vector maps of the study area were collected and seismic sources were identified and characterized as line, point, and areal sources. Linear seismic sources were identified from the Seismotectonic atlas (SEISAT, 2000) published by the GSI, in addition to the source details collected from available literature and remote sensing images. The SEISAT map contains 43 maps presented in 42 sheets covering entire India and adjacent countries with 1:1million scale. Sheets representing the features of the study area were scanned, digitized and georeferenced using MapInfo 10.0 version. After this, tectonic features and seismicity events were superimposed on the map of the study area to prepare a Seismotectonic Map with a scale of 1:1million. In seismic hazard assessment, a state of art well known methodologies (deterministic and probabilistic) was used. In deterministic seismic hazard analysis (DSHA) procedure, hazard assessment is based on the minimum distance between sources to site considering the maximum magnitude occurred at each source. In hazard estimation procedure a lot of uncertainties are involved, which can be explained by probabilistic seismic hazard analysis (PSHA) procedure related to the source, magnitude, distance, and local site conditions. The attenuation relations proposed by Atkinson and Boore (2003), and Gupta (2010) are used in this analysis. Because in this region two type activities are mostly observed, regions such as SP, and EH are under plate boundary zone whereas IBR is under subduction process. These equations (GMPEs) were validated with the observed PGA (Peak ground acceleration) values before use in the hazard evaluation. The hazard curves for all six major sources were prepared and compiled to get the total hazard curve which represents the cumulative hazard of all sources. Evaluation of PGA, Sa (0.2s and 1.0s) parameters at bedrock level were estimated considering a grid size of 5 km x 5 km, and spectral acceleration values corresponding to a certain level of probability (2% and 10%) were done to develop uniform hazard spectrum (UHS) for both the cities (Agartala and Aizawl). To carry out the seismic microzonation of Agartala and Aizawl cities, a detailed study using geotechnical and geophysical data has been carried out for site characterization and evaluation of site response according to NEHRP (National Earthquake Hazard Response Program) soil classifications (A, B, C, D, and E-type). Seismic site characterization, which is the basic requirement for seismic microzonation and site response studies of an area. Site characterization helps to have the idea about the average dynamic behavior of soil deposits, and thus helps to evaluate the surface level response. A series of geophysical tests at selected locations have been conducted using multichannel analysis of surface waves (MASW) technique, which is an advanced method to obtain direct shear wave velocity profiles from in situ measurements for both the cities. Based on the present study a major part of Agartala city falls under site class D, very few portions come under site class E. On the other hand, Aizawl city comes under site class C. Next, a detailed site response analysis has been carried out for both the cities. This study addresses the influence of local geology and soil conditions on incoming ground motion. Subsurface geotechnical (SPT) and geophysical (MASW) data have been obtained and used to estimate surface level response. The vulnerable seismic source has been identified based on DSHA. Due to the lack of strong motion time history of the study area, synthetic ground motion time histories have been generated using point source seismological model (Boore 2003) at bedrock level based on fault rupture parameters such as stress drop, quality factor, frequency range, magnitude, hypocentral distance etc. Dynamic properties such as the shear modulus (G) and damping ratios (ζ) have been evaluated from the soil properties obtained from SPT bore log data collected from different agencies such as PWD (Public works Department), and Urban Development Dept. of the State Government, in situ shear wave velocity has been obtained from MASW survey in different locations, and following this, a site response analysis has been carried out using SHAKE-2000 to calculate the responses at the ground surface in combination of different magnitudes, distances and epicentral depth for a particular site class. An amplification factor was estimated as the ratio of the PGA at the ground surface to the PGA at bedrock level, a regression analysis was carried out to evaluate period dependant site coefficients, and hence, the period dependant hazard impact on the ground surface could be calculated to obtain the spatial variation of PGA over the study area. Further, liquefaction potential of the site (Agartala) was also evaluated using available SPT bore log data collected and using presently estimated surface level PGA. The results are presented in the form of liquefaction hazard map representing as a Factor of safety (FS) against liquefaction with various depths such as 1.5m, 10m, and 15m respectively. It has been seen that Agartala city shows highly prone to liquefaction even up to 15 m depth. Hence, site specific study is highly recommended for implementing any important project. The liquefaction hazard assessment could not be conducted for the Aizawl city because of non availability of the SPT-N data, however, the city stands on hills/mountains, and therefore, such a study is not applicable in this area. Further, seismic microzonation maps for both the cities have been prepared considering Analytical Hierarchy Process (AHP) which support to the Eigen value properties of the system. Two types of hazard maps have been developed, one using deterministic and another using the probabilistic seismic microzonation maps. These maps can be directly used as inputs for earthquake resistant design, and disaster mitigation planning of the study area. However, an investigation has also been made in forecasting a major earthquake (Mw>6) in North-East India using several probabilistic models such as Gamma, Weibull and lognormal models. IBR and EH show a high probability of occurrences in the next 5 years (i.e. 2013-2018) with >90% probability.

Tee present research focuses on seismic hazard studies for the states of Tripura and Mizoram in the North-East India with taking into account the complex sesismotectonic characteristics of the region. This area is more prone to earthquake hazard due to complex subsurface geology, peculiar topographical distribution, continuous crustal deformation due to the under thrusting of Indian and the Eurasian plates, a possible seismic gap, and many active intraplate sources identified within this region. The study area encompasses major seismic source zones such as Indo Burmese Range (IBR), Shillong Plateau (SP), Eastern Himalayan arc (EH), Bengal Basin (BB), Mishmi Thrust (MT) and Naga Thrust (NT). Five historical earthquakes of magnitude Mw>8 have been listed in the study area and 15 events of magnitude Mw>7 have occurred in last 100 years. Indian seismic code BIS-1893-2002 places the study area with a high level of seismic hazard in the country (i.e. seismic zone V). More than 60% of the area is hilly steep-terrain in nature and the altitude varies from 0 to 3000 meters. Recent works have located a seismic gap, known as the Assam gap since 1950 between the EH, SP, and IBR with the Eurasian plate. Various researchers have estimated the return period, and a large size earthquake is expected in this region any time in future. The area is also highly prone to liquefaction, since rivers in Tripura (Gomati, Howrah, Dhalai, Manu, Bijay, Jeri, Feni) and the rivers in Mizoram (Chhimtuipui, Tlawng, Tut, Tuirial and Tuivawl etc.) are scattered throughout the study area where soil deposits are of sedimentary type. In 2011, both the states together have experienced 37 earthquakes (including foreshocks and aftershocks) with magnitudes ranging from 2.9 to 6.9. Of these events, there were 23 earthquakes (M>4) of magnitudes M6.4 (Feb 4th 2011), M6.7 (March 24th 2011), M6.9 (Sept.18th 2011), M6.4 (October 30th 2011), M6.9 (Dec 13th 2011), M5.8 (Nov 21st 2011), M5 (Aug 18th 2011), M4.9 (July 28th 2011), M4.6 (Dec 15th 2011), M4.6 (Jan 21st 2011), M4.5 (Dec 9th 2011), M4.5 (Oct 21th 2011), M4.5 (Oct 17th 2011), M4.5 (Sept 18th 2011), M4.3 (Oct 10th 2011), M4.3 (Sept 22nd 2011), M4.3 (April 4th 2011), M4.2 (Sept 9th 2011), M4.2 (Sept 18th 2011), M4.1 (April 29th 2011), M4.1 (Feb 22nd 2011), M4 (June 9th 2011), and M4 (Dec 2nd 2011) which occurred within this region [source: IMD (Indian Metrological Department), India]. The earthquake (M6.9) that occurred on Sept. 18th 2011 is known as the Sikkim earthquake, and it caused immense destruction including building collapse, landslides, causalities, disrupted connectivity by road damages and other infrastructural damages in Sikkim state as well as the entire North-East India. In the cities of Agartala and Aizawl of Tripura and Mizoram, construction of high rise building is highly restricted by the Government. Being the capital city, many modern infrastructures are still pending for growth of the city planning. Although many researchers have studied and reported about the status of seismicity in North-East Region of India, very few detailed studies have been carried out in this region except Guwahati, Sikkim and Manipur where almost the whole of the study area is highly vulnerable to severe shaking, amplification, liquefaction, and landslide. From the available literature, no specific study exists for Tripura and Mizoram till date. In the present research, seismic hazard assessment has been performed based on spatial-temporal distribution of seismicity and fault rupture characteristics of the region. The seismic events were collected from regions covering about 500 km from the political boundary of the study area. The earthquake data were collected from various national and international seismological agencies such as the IMD, Geological Survey of India (GSI), United State Geological Survey (USGS), and International Seismological Centre (ISC) etc. As the collected events were in different magnitude scales, all the events were homogenized to a unified moment magnitude scale using recent magnitude conversion relations (region specific) developed by the authors for North-East Region of India. The dependent events (foreshocks and aftershocks) were removed using declustering algorithm and in total 3251 declustered events (main shocks) were identified in the study area since 1731 to 2011. The data set contains 825 events of MW < 4, 1279 events of MW from 4 to 4.9, 996 events MW from 5 to 5.9, 131 events MW from 6 to 6.9, 15 events MW from 7 to 7.9 and 5 events MW ≥8.
