Résumé :
The groundwater quality of Koch Bihar District (West Bengal, India) has been assessed to determine the suitability of groundwater for drinking. Eight parameters have been taken into account for calculating the water quality index (WQI): pH, total hardness (TH), magnesium (Mg), calcium (Ca), carbonate (CO32-) and bicarbonate (HCO3-), chloride (Cl), iron (Fe) and sulfate (SO42-). Secondary data on water quality were collected from Central Ground Water Commission (2018), and the samples of water have been collected from the various locations and analyzed accordingly. The physico-chemical data were evaluated following the standards of BIS and WHO guidelines. The calculated WQI ranges from 23.62 to 95.12. In terms of groundwater quality for drinking purposes, Tufanganj-1 and Koch Bihar-1 seem to be the worst blocks. The magnesium (Mg) concentration exceeds the acceptable limit of 30 mg/l in Mathabhanga I, Mathabhanga II, Koch Bihar II, Dinhata II, and Sitai Block and Koch Bihar II exceeds its permissible limit (100mg/ l). The Iron (Fe) value exceeds the acceptable limit of 0.5 mg/l in Koch Bihar II. The Total Hardness (TH) value exceeds the acceptable limit (200 mg/l) in Mekhliganj, Mathabhanga-I, Koch Bihar-I, Koch Bihar-II, Tufanganj II, Dinhata II, Sitai. However, no sample crosses the maximum acceptable limit for pH, carbonate, chloride, and sulfate. It is suggested that water drawn from such sources be disinfected adequately before being used for drinking or other domestic purposes.

Résumé :
Soil refers to the upper layer of the Earth’s surface, which is made up of a mixture of organic residues, clay, and rock particles, and that's where plants grow. The soil quality is the environmental aspect that is most significant in agricultural activities, as well as for the concern of the safety of agricultural produces. At present-day, soil quality assessment becomes the most important issue because of the raising food security awareness. This study was assessed in Koch Bihar district, West Bengal, India, to quantify soil quality using the weighted Soil Quality Index (SQI) approach. For this assessment, the soil-related data were collected from the Soil Health Card (SHC) of the Agricultural Development Offices in all blocks of Koch Bihar and then analyzed using the principal component analysis (PCA) and expert opinion (EO) method. The weights of the selected soil quality indicators were determined using the integrated Fuzzy-AHP model. According to this method, 12 indicators, i.e., soil pH, soil electrical conductivity (EC), soil organic carbon content, nitrogen content, potassium content, phosphors content, soil texture, the groundwater level in the winter season, cropping intensity, and drainage frequency were considered based on literature review. The SQI assessment was done accordingly for each spatial unit (Block), and the spatial variability of the soil quality map was produced by GIS spatial analysis module. The findings may aid in promoting non-harmful produce production, the provision of scientific data for agricultural structure adjustment, and the maintenance of agricultural sustainability.

Résumé :
The increase in population is becoming a comprehensive dilemma, causing much pressure alternative medicine for anti-fertility action. Ayurveda and other Indian literature mention the use of plants in various human ailments. India has about more than 45000 plant species and among them several thousand are claimed to possess medicinal properties. Researchers conducted in the last few decades on the plants mentioned in ancient literature or used traditionally for anti-fertility action. This review reveals that some plants and their part used having anti-fertility action, which are helpful for researcher to develop new herbal anti-fertility formulations. In the recent years, interest in drugs of plant origin has been progressively increased. The Koch Rajbangshi people use various wild and cultivated plants as medicine for curing different diseases. They completely or partially depend upon these plants for curing various diseases. The plants are mostly used as first aid treatment in most of the diseases. In almost every village there is a medical man who generally knows the traditional uses of the plants. There are some ritual believes also associated with these medicinal plants or ethnomedicines. A good number of these plants are also included in their daily diet. Above all, the plants have also some market value, thus playing an important socio-economic role among the people of the various tribal people. With the use of modern day medical techniques the traditional health care system is now at the verge of extinction. In the present work, the Researcher tried to document the plants used for the medicinal purposes in the, District Cooch Behar or Koch Bihar of the North Bengal region. To create a database of traditional knowledge and use pattern of some plants with infertility potential by Koch or Rajbangshi people in the region all the plants with its uses are documented in this study.

Résumé :
AbstractManasā is a very important goddess of the eastern part of India, particularly for the lower castes of Bengal, West Assam, some districts of Odisha, Jharkhand and Bihar. She is the main goddess for the majority of Rajbansis of North Bengal. The fluid border between deities, witches and human beings is an essential part of both her myth and cult. Being a Tāntric deity, Manasā has an extremely ambivalent character: according to the narratives and ritualistic practice she is at the same time both welcomed and unwanted. Her worship involves negotiation with dangerous divine power, which generates insecurity and uncertainty, but at the same time rewards adepts with wonderful abilities. This paper is based on ethnographic fieldwork conducted by the author in rural places in the Jalpaiguri, Koch-Behar, Goalpara and Darrang districts of West Bengal and Assam, India, among Rajbansis, Bodo Kachari and Assamees. The details of Manasā worship, Behula dance and storytelling by Bengali Monośa gidal, and in a form of Assamese suknāni ojha-palli (with deodhani dance and trance) will reveal a peculiar local knowledge system, directly aimed at overcoming and transforming mundane life crises.

Texte intégral
Résumé :
The present study analyses rural to urban migration and the growth of urban centres in the Himalayan foothill region (Jalpaiguri, Alipurduar and Koch Bihar) of West Bengal and investigates the role of migration in urban growth and processes in this region. The study is based on data from the Census of India (migration table and general population table) from 1951 to 2011. Geospatial techniques have been used to show the evaluation, spatial distribution and growth of urban centres in the recent past. The study found that from 1951 to 2011, the total population increased by 4 times, while the total urban population increased by 10 times, and the number of urban centres increased by 7 times, which is higher than the national level. The proportion of the urban population and the concentration of urban centres show that urbanisation in the Himalayan foothill region is mainly concentrated in the district headquarters. The study also illustrates that migration towards urban centres is a dominant factor contributing to the progress and growth of urban centres in this region. Moreover, the growth of new urban centres, the direction of urban growth and the contribution of migration to urban growth predict that Koch Bihar and Alipurduar urban agglomerations will join together and emerge as twin cities in the Himalayan foothill region.

Résumé :
Experiments were carried out at ten locations of Saran district, Bihar during kharif season 2017 with okra crop cv ‘Supper green’. The assessment reveled that module (M4) proved the most effective treatment against okra pest and diseases i.e. shoot and fruit borer, Earias vittella F., yellow vein mosaic virus, Bemisia tabaci (Genn.) and red spider mites, Tetranychus urticae Koch in which lowest incidence was recorded as compared to other IPM modules, farmer practices and control plot during 2017. IPM Module III (shoot and fruit borer 7.02% on shoot, 9.87% on fruits, yellow vein mosaic virus 16.25% and red spider mites 3.35% infestation) was next effective against the major pest of okra crop in compression to IPM modules I (shoot and fruit borer 12.24% on shoot, 18.12% on fruits, yellow vein mosaic virus 24.42% and red spider mites 9.05% infestation), respectively. Significantly, maximum fruit yield was observed in module IV 210.10 q/ha. This was significantly superior over all other module. The impact of various IPM modules showed that net return was also higher in module IV which was Rs.76430.00/ha.

Résumé :
The availability and accessibility of essential services and facilities are key in promoting living conditions. In India, regional differences and development inequities are major obstacles to sustainable development. The main objectives of this study are to analyse the level and pattern of the standard of living and explore inequality in the case of accessibility to basic services and amenities in Rural West Bengal. All data was collected from the Primary Census Abstract (PCA) and Housing and Household Basic Amenities Table from Census 2011. A composite index has been developed to measure the standard of living of rural households. This study also used the Location quotient and Pearson correlation method to measure the concentration level of different household facility and their relationship. This study reveals that there is a very high level of disparity of the level of development in terms of rural household living standards. The rural living standard is very high in norther region (Darjeeling and Koch Bihar) and middle part (Haora district) due to economic opportunity. Most of the districts have low coverage of various parameters of housing conditions, availability of basic amenities, and availability of assets. This study will guide policymakers in the future in making better policies

Résumé :
Aphids are small, soft bodied, polyphagic and polymorphic sap sucking insects. During the extensive survey of different localities of 10 districts of northeast Bihar in different seasons, 41 species of aphids were recorded on more than 122 plant species belong to 35 families. Among these, only 09 species of Aphis viz., Aphis affinis Del Guercio, Aphis craccivora Koch, Aphis fabae Scopoli, Aphis glycine Matsumura, Aphis gossypii Glover, Aphis nasturtii Kaltenbach, Aphis nerii Boyer de Fonscolombe, Aphis puniceae Passerini and Aphis spiraecola Patch were recorded in the target area. The maximum number of plants were infested by A. gossypii (46 plants), followed by A. craccivora (36 plants), A. nasturtii (18 plants) and A. spiraecola (18 plants). Six species of coccinellids (Cheilomenes sexmaculata (Fabricius), Coccinella septempunctata Linnaeus, Coccinella transversalis Fabricius, Micraspis discolor (Fabricius), Pseudospidimerus circumflexa var. testaceus (Weise) and Scymnus pyrocheilus (Mulsant) and six species of syrphid predators (Allograpta javana (Wiedemann), Asarkina ericetorum (Fabricius), Episyrphus balteatus (DeGeer), Ischiodon scutellaris (Fabricius), Melanostoma orientale (Wiedemann) and Paragus serratus (Fabricius)) were recorded on Aphis spp. in the target area. Seven species of parasitoids viz, Aphelinus albipodus Fatima & Hayat, Aphelinus basilicas Fatima & Hayat, Aphelinus gossypii Timberlake, Aphelinus sp., Aphidius sp., Binodoxys indicus Subba Rao & Sharma and Lipolexis oregmae (=scutellaris) (Gahan) were also recorded on Aphis spp. in the target area. Six species of predators (C. sexmaculata, C. septempunctata, C. transversalis, E. balteatus, I. scutellaris and P. serratus) and three species of the parasitoids (A. gossypii, B. indicus and L. oregmae) were found abundantly on Aphis spp. in the target area and may be utilised in the biological control programme after further study
