  • Land Tenures in Cooch Behar District, West Bengal: a Study of Kalmandasguri Village Ranjini Basu*
    RESEARCH ARTICLE Land Tenures in Cooch Behar District, West Bengal: A Study of Kalmandasguri Village Ranjini Basu* Abstract: This paper describes and analyses changes in land tenure in Cooch Behar district, West Bengal. It does so by focussing on land holdings and tenures in one village, Kalmandasguri. The paper traces these changes from secondary historical material, oral accounts, and from village-level data gathered in Kalmandasguri in 2005 and 2010. Specifically, the paper studies the following four interrelated issues: (i) land tenure in the princely state of Cooch Behar; (ii) land tenure in pre-land-reform Kalmandasguri; (iii) the implementation and impact of land reform in Kalmandasguri; and (iv) the challenges ahead with respect to the land system in Kalmandasguri. The paper shows that an immediate, and dramatic, consequence of land reform was to establish a vastly more equitable landholding structure in Kalmandasguri. Keywords: Kalmandasguri, Cooch Behar, West Bengal, sharecropping, princely states, history of land tenure, land reform, village studies, land rights, panel study. Introduction This paper describes and analyses changes in land tenure in Cooch Behar district, West Bengal.1 It does so by focussing on land holdings and tenures in one village, Kalmandasguri.2 The paper traces these changes by drawing from secondary historical material, oral accounts, and from village-level data gathered in Kalmandasguri in 2005 and 2010.

    Forest Fire Prediction Modeling in the Terai Arc Landscape of the Lesser Himalayas Using the Maximum Entropy Method Amit Kumar Verma and Namitha Nhandadiyil Kaliyathan, Forest Research Institute, Dehradun, India; Narendra Singh Bisht, Arunachal Pradesh Forest Department, India; and Satinder Dev Sharma and Raman Nautiyal, Indian Council of Forestry Research & Education, Dehradun, India Abstract—The Terai Arc Landscape (TAL) is an ecologically important region of the Indian subcontinent, where anthropogenic habitat loss and forest fragmentation are major issues. The most prominent threat is forest fires because of their impacts on the microhabitat and macrohabitat characteristics and the resulting disruption of ecological processes. Moreover, wildfire aggravates conflicts between humans and wildlife in the forest fringe areas. The lack of a proper forest fire monitoring system in the TAL is a major management issue that needs attention for long-term forest viability. Hence, the present study was undertaken using maximum entropy modeling to predict the areas across the TAL at risk of wildfire and to identify key variables associated with fire occurrence. Spatiotemporally independent fire incidence locations along with other environmental variables were used to build the model. The accuracy of the model was assessed using the area under the curve. To evaluate the importance of each variable, a jackknife procedure was adopted. Areas in the projected map were categorized into high fire, marginal fire, and no fire areas. An adaptive forest management strategy can be implemented in the modeled high fire areas to mitigate forest fire and wildlife conflict in the TAL. Keywords: forest fire, maximum entropy, Terai Arc Landscape, Tiger INTRODUCTION biodiversity (Dennis and Meijaard 2001) because of changes in climate and in human use and misuse of A forest fire, whether caused by natural forces or fire.

Gorkha Janmukti Morcha. Darjeeling hills. Development. Interethnic relationships. Identity. Autonomy. ABSTRACT: The existing research work deals with an understanding of interethnic relationships among the ethnic communities of Darjeeling district and Dooars after the formation of Gorkhaland Territorial Administration (GTA) in Darjeeling hills. A brief introduction of the ethnic geography of Darjeeling district and Dooars has been made to know how significant are the interethnic relationships among these ethnic communities since the formation of GTA. Does the formation of GTA influence these interethnic relationships among its members? The author attempts to know why there are changes, if any, in their relationships, and what are the implications/significances of these changed relationships on the autonomy movement i.e. Gorkhaland movement, as the formation of the GTA is outcome of that movement.

  • Migration to and from the Nepal Terai: Shifting Movements and Motives Hom Nath Gartaula and Anke Niehof
    Migration to and from the Nepal terai: shifting movements and motives Hom Nath Gartaula and Anke Niehof Vol. 2, No. 2, pp. 29–51 | ISSN 2050-487X | journals.ed.ac.uk/southasianist journals.ed.ac.uk/southasianist | ISSN 2050-487X | pg. 29 Vol. 2, No. 2, pp. 29-51 Migration to and from the Nepal terai: shifting movements and motives Hom Nath Gartaula University of Manitoba, Canadian Mennonite University, [email protected] Anke Niehof Wageningen University, [email protected] In Nepal, the historical evidence shows that migration to the terai increased after the eradication of malaria in the late 1950s and has been increasing ever since. More recently, however, out-migration from the terai is rapidly increasing. By applying both qualitative and quantitative research methods, in-depth qualitative interviews, focus group discussions and household survey were used for data collection, with considerable inputs from ethnographical fieldwork for about 21 months. The paper presents three types of population flows in the historical pattern. First, the history of Nepal as an arena of population movement; second, the gradual opening up of the terai, leading to the hills-terai movement; and the third, the current outward flow as an individual migration for work. The paper exemplifies that poverty and lack of arable land are not the only push factors, but that pursuing a better quality of life is gaining importance as a migration motive. We conclude that like movements of people, their motives for moving are also not static and cannot be taken for granted. journals.ed.ac.uk/southasianist | ISSN 2050-487X | pg.

  • Chapter – Ii Demographic Profile and Social Structure of Terai
    DEMOGRAPHIC PROFILE AND SOCIAL STRUCTURE OF TERAI CHAPTER – II DEMOGRAPHIC PROFILE AND SOCIAL STRUCTURE OF TERAI The District of Darjeeling of present West Bengal consists of three distinct tracts, viz, (i) the thanas of Darjeeling, Jorbangla and Kurseong i.e. the whole of the hills except the Kalimpong outpost, most of this was ceded by the Raja of Sikkim in 1835, (ii) the Kalimpong outpost taken from Bhutan in 1865 and (iii) the Terai i.e. the Siliguri 1 thana annexed from Sikkim in 1850. The Geographical and religious structure of the Terai region with its multi-racial and multi-lingual character reminds us of the Indian diversity in races, culture and language. This feature has, therefore, provoked many scholars to refer North Bengal as ‘little India’. Prior to the Colonial period the regions of North Bengal were covered with dense forests and it was an area of Kala-Azar, Malaria and ferocious and dangerous animals .Various sources state that there was the practice of agriculture among the inhabitance of people in this regions.2 The records declare that the Terai had a scanty population with very rare settlements, mostly tribal. The Report of 1839 states that there were of inhabitance of few Mech population in the Darjeeling Terai when the British 3 received Darjeeling in 1835 as a gift from the Raja of Sikkim. According to Campbell, the first Superintendent of Darjeeling, there were 400 Mech families in Terai in 1839.4When the British ceded Darjeeling in 1835, the Terai area was covered with deep forest. It was a dump and most un-healthy place of Northern Bengal.

  • Problem Tiger in the Sundarbans
    Journal of the Fauna Preservation Society February 1976 A reprint from Volume XIII No 3 s *• .'t«íA^'* ^. VILLAGE on reclaimed land near where the tiger was captured Problem Tiger in tlie Sundarbans John Seidensticker, R. K. Lahiri, K. C. Das, and Anne Wright In August 1974 a young male tiger moved into a populated area in the Sundar- bans, the delta of the Ganges, and killed one woman and a number of livestock. Rather than destroy the animal the Forest Directorate decided to capture it, using immobilising drugs, and release it in the Sundarbans Tiger Reserve. This was successfully done, but less than a week later it was found dead from wounds evidently inflicted by another tiger. The authors discuss the implications of the incident, the publicity it attracted, and the changes in public attitudes. In the early morning of August 2nd, 1974, a tiger was reported to have killed a woman near the village of Jharkhali, 70 km. south-east of Calcutta, in a re- claimed part of the Sundarbans in the Ganges delta. The tiger was sighted repeatedly over the next few days, and people were very alarmed. On August 7th, the State Wildlife Officer, R. K. Lahiri, arrived by motor launch to investigate and report to the West Bengal Forest Directorate, the authority responsible under the 1972 Wild Life Protection Act. The tiger was roaming in a densely populated region of a large delta island, a mosaic of paddy fields, villages and a large central mangrove marsh used as a fishery. The area had been part of reserve forest lands until about 1955, when it was reassigned for the resettlement of refugees.

Subsequently blessed with human resource support from National Agricultural Research Project (NARP) in 1990, the research activity of the Station achieved a strategic boost through formulation of bench level study of the zone. The goal setting was done on the basis of identified rationales and the task was accomplished by dedicated participation of multi- disciplinary group of scientists each committed to his/her own field. In 2001, the Station extended adequate support in formulation of new Directorate of Research of Uttar Banga Krishi Viswavidyalaya (UBKV) born out of bifurcation of BCKV and since then it became a constituent of the same. This also incurred some static change in scientists group through optional discontinuity of few seniors and subsequent refilling by fresher.

  • Y-Chromosome Haplogroup Diversity in the Sub-Himalayan Terai and Duars Populations of East India

Analysis of the paternal genetic diversity of the populations inhabiting these regions and their genetic relationships with adjacent Himalayan and other Asian populations has not been addressed empirically. In the present investigation, we undertook a Y-chromosome phylogeographic study on 10 populations (n¼375) representing four different linguistic groups from the sub-Himalayan Terai and Duars regions of East India. The high-resolution analysis of Y-chromosome haplogroup variations based on 76 binary markers revealed that the sub-Himalayan paternal gene pool is extremely heterogeneous. Three major haplogroups, namely H, O and R, are shared across the four linguistic groups. The Indo-European-speaking castes exhibit more haplogroup diversity than the tribal groups. The findings of the present investigation suggest that the sub-Himalayan gene pools have received predominant Southeast Asian contribution. In addition, the presence of Northeast and South Asian signatures illustrate multiple events of population migrations as well as extensive genetic admixture amongst the linguistic groups.
