Bangladesh is vulnerable to thunderstorm disasters due to its location and weather conditions. Rural people are severely affected by a thunderstorm. For this research, necessary data were collected from secondary as well as primary sources. Thunderstorm related information was randomly gathered from the 150 affected family members and close relatives. The study demonstrated that the working people especially farmers and school going students were severely affected. The research also identified impacts of thunderstorms on humans, types of damage and monetary loss. In terms of thunderstorm induced casualty, the number of death was higher than other casualties in the study area. This research also revealed that above 67 % of people succumbed to death by the thunderstorms which damaged crops, households, animals and trees. People in the study area also suffered from physical damage, for example, injuries to ears, eyes, and body. More than 37% of people faced hearing problems due to strikes of thunderstorms. The study also identified the risk factors responsible for the thunderstorms, such as lack of knowledge about a thunderstorm, outdoor activities, diurnal, and locational variation. Policymakers and planners will find insights from this research to mitigate the impact of thunderstorm disasters in rural Bangladesh.","PeriodicalId":160152,"journal":{"name":"National Geographical Journal of India","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129470390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Evaluation of morphometric characteristics of Betwa drainage basin","authors":"Neetesh Kumar, Jagadish Singh","doi":"10.48008/ngji.1775","DOIUrl":"https://doi.org/10.48008/ngji.1775","url":null,"abstract":"The morphometric analysis of any drainage basin is considered useful for water resource studies such as flood assessment, water quality sampling, water use reporting, watershed management etc. Drainage basin is generally defined as the areal extent of land from which the surface runoff flows to a defined drain, channel, stream or river. It is mainly governed by the topography of the terrain. Geographical Information System and Image Processing Techniques can be used for the identification of morphological features and analyzing properties of the basin. The morphometric parameters include linear, areal and relief aspects. ‘Watershed Atlas of India’ (2014) on 1:50,000 scale is an important digital database for planning and monitoring of development programs on a watershed basis. It serves as a uniform baseline for developing a hydrological unit-based data bank to be used for the management of water resources in the country. Run-off, sedimentation, water balance, evapotranspiration and several other catchment characterization related studies may be taken up on a watershed basis. The present study deals with morphometric parameters such as stream order (Nu), stream length (Lu), bifurcation ratio (Rb), drainage density (D) and stream frequency (Fs) of the Betwa drainage basin. Geographically the basin (77° 30′ to 80° 12′ east longitudes and 23°30′ to 25°55′ north latitudes) is located in two states i.e. Madhya Pradesh and Uttar Pradesh occupying an area of 43780 km2. The length of the stream segment is maximum for the first-order stream and decreases as the stream order increases. This study would help in understanding the hydrological behaviour of the basin. This, in turn, may enable the local people to utilize the resources of the basin for the sustainable development of the area.","PeriodicalId":160152,"journal":{"name":"National Geographical Journal of India","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124366081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There has been a growing concern over the accessibility and affordability of healthcare facilities. The spread of the ongoing pandemic COVID-19 has been felt all over the world. However, the rate of infection varies across certain regions of the world. There exists intra-regional disparity as well. Recent research shows that there are latitudinal and altitudinal variations in the spread of the COVID-19. This paper studies variation of infection COVID-19 across the highlands of the Indian Himalayan Region (IHR) and the lowland areas in India. The paper also examines the role of geographical spaces in the spread of coronavirus in these regions. The study indicates that place-based effects (altitude, temperature, pollution levels, etc.) on health can be seen in a variety of ways; therefore, locational issues are very important for addressing health questions. The paper also analyses the Spatio-temporal pattern of the COVID-19 pandemic in the study area to understand the nature of the disease in different locations.","PeriodicalId":160152,"journal":{"name":"National Geographical Journal of India","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129437501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is the activities by which people secure their livelihood and it also provides background knowledge for formulating development plans for any region. The paper presents the occupational structure of rural workers in the Mathura district. Mathura district is situated in the western part of Uttar Pradesh and has a high religious and economic importance. The whole study is mainly based on primary data collected through a structured interview schedule designed for the purpose. Field surveys were conducted during 2015-16 and 5270 respondents (2929 males and 2341 females) of 755 households were questioned to generate primary data. In the surveyed villages, the share of cultivation and agricultural labourers was 44.41 % and 16.32 % respectively. A large share of workers was engaged in primacy activities (66.73%). The analysis shows that there is a negative relationship between workers and literacy rate. It happens because as people get employment in cities they leave the village and only unemployed literates stay there. The results were derived with the help of statistical techniques and SPSS software whereas maps were prepared with the help of GIS Arc View software.","PeriodicalId":160152,"journal":{"name":"National Geographical Journal of India","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128796775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The quantitative techniques applied for linear, aerial and relief aspects of the drainage basin elucidate the rate of erosion, the intensity of denudation and subsequently the potential of the Nandakini river basin to flooding. The morphometric analysis of the Nandakini river basin in the Garwhal Himalayan region of Uttarakhand reveals that the Rf value of the Nandakini river basin is 0.28, indicating an elongated basin shape leading to quick flooding and poor draining out of floodwaters. Similarly, an elevation difference between the highest and lowest elevation is 5380 metres aids quick runoff and deposition of eroded debris in the drainage channels, another cause of channel overflow. The Rh value is high (0.12), indicating a high channel gradient with intense erosional processes operating due to steep gradient and this has a considerable impact on the rate of erosive geomorphic processes operating. The higher elevation on the Eastern part of the basin due to the Vaikrita Thrust, the Munsiyari Thrust (ie. the southern tilting Main Central Thrust) and the Baijnath Klippe has resulted in metamorphism in Miocene and Pliocene explaining the low rate of infiltration and rapid runoff.","PeriodicalId":160152,"journal":{"name":"National Geographical Journal of India","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122108289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
