It provides social, economic, health and environmental benefits to the urban people in a city. Bangladesh's third largest city is Khulna, which is dominated by agriculture, two of the Wards of this city namely Ward no. 17 and Ward no. 20 are selected as the study area for this study. In many established and developing countries, community gardening is a common feature of urban development, but it is a new concept in Bangladesh. The study aims at exploring the potentials i.e., factors or favorable reasons of introducing community gardens in Khulna City. A wide range of related literature on community gardens are reviewed. A total of 300 households of the study Wards are surveyed through semi-structured questionnaire, key informant interviews of urban planners, civil engineers, architects, agriculturist, environmentalist and sociologist are conducted with review of Khulna City master plans, and other reports and publications. The study finds that approximately 3. 67 acres and 2.43 acres land in Ward no. 17 and Ward no. 20 remain vacant respectively. Also, after knowing the pros and cons of CG, 58.33% people in Ward no. 17 and 60% people of Ward no. 20 become interested to participate in CG. If it is possible to utilize the vacant land for community gardening, community gardens on one acre land having 17 decimal or 10.30 katha land of each community garden will be capable to sequestrate about 3.5 tons of carbon per year and depending on the size and duration of rain event, will be able to hold about 2000-10000 cubic ft. of storm water per year. The study also proposes some sites for the development of community gardens in future.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132268623","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}

This research aims to assess the spatial distribution of parks as urban green space of Khulna City in equity planning. Primary data on existing condition of parks with facilities, user satisfaction level, improvement of existing parks, and proposals for new parks etc. are collected from questionnaire survey of 384 park users and key informants of urban planners, civil engineers and architects from Khulna Development Authority (KDA) and Khulna City Corporation (KCC), the city planning and urban service delivery government organizations. Implementation status of park proposals in 1961 and 2001 City Master Plans, and proposals in the 2018 Detailed Area Development Plan (DAP) along with relevant published research articles, reports etc. are reviewed as secondary data sources. Demand for parks is assessed through Buffer and Network analysis using GIS and also from Threshold Population analysis. Khulna, the 3rd largest industrial city of Bangladesh has about 0.7 million people in its 45.65 sq. km area. There are only 8 parks in Khulna City, most of which are small and cover only 0.15% of total KCC area. Among the 31 KCC Wards, only 7 (23%) Wards, where 27% city people live have parks. The remaining 24 (77%) Wards having 73% city people are deprived of parks. Increased urban population due to rapid urbanization is causing tremendous pressure on the existing limited number of parks. KCC and KDA have not followed equity principles while planning and implementation of park proposals. The parks are mostly found in the Wards having planned and old built-up areas. The existing parks are unable to fulfill the demand of city people. Considering the served, over served and underserved area of existing parks in a more conservative manner, a total of 14 new parks are proposed to ensure equity in planning and development of parks in Khulna City.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"10 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127108430","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}

Broad and easy access to mobile devices and social media has created immense opportunities for the public to share and publish their works on open forums. The audience as the prosumer (producers and active consumers) generates ‘user-generated content’ that undoubtedly influences the mainstream media’s content production procedure and manner through distributing them to many news or social platforms. This process leads to citizen journalism as a parallel mode of journalism where collection, collaboration and dissemination of the information go through a single channel. This study is based on both primary and secondary data sources to understand the impacts, challenges, and opportunities of citizen journalism needed beside the journalism. The qualitative data are collected from seven in-depth interviews with senior journalists, editors, academics and news managers. And two semi-structured interviews were conducted with citizen journalism project coordinators. Their analysis regarding this citizen journalism practices in mainstream media creates access to information by opening a new door to more significant resources. However, the concern remains whether incorporating citizen journalism into mainstream journalism poses any threat or not. It is observed that the absence of practicing journalistic rules and regulations in social media makes their credibility questionable and generates confusion. Online news sites use mobile technologies to create and disseminate their media products, gradually attracting the audience and readers. As a result, people are often used to accessing news from online sites rather than print media. With this current demand, mainstream news media is focusing on more interactivity on their online platforms and encouraging their audiences to join in the news production process.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131408323","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 purpose of this study was to explore the effects of probiotics in neonatal STZ-induced type-2 diabetic rats. Following the biochemical analysis of probiotic bacteria, yogurt was prepared using cow milk and used to feed the experimental rats. Probiotic yogurt was supplemented to three rat groups, each with six rats, and the doses were 2 g in PYT1, 4 g in PYT2 and 6 g in PYT3 for 21 days. Fasting serum glucose, serum insulin, lipid profiles and liver glycogen levels were measured to investigate the probiotic effects on type 2 diabetic rats. It was observed that fasting serum glucose levels were significantly lower in case of PYT3 group (p<0.05) whereas a significant (p<0.05) upsurge of serum insulin levels was detected in PYT2 rat group. A significant (p<0.05) decrease in LDL level in PYT2 group and significantly (p<0.05) increased level of HDL was detected in PYT1 and PYT2 rat groups. However, there were no significant differences regarding triglyceride as well as total cholesterol levels among three probiotic yogurt supplemented rat groups. Hepatic glycogen content was 34.5%, 30.9% and 39.1% among the probiotic yogurt feed groups viz. PYT1, PYT2 and PYT3, respectively. Findings of this research suggest that application of probiotic yogurt can help to manage type-2 diabetes.

The numbers of filled grain and unfilled grain plant-1 and yields of grain and straw m-2 were the highest from the above-mentioned combination. The lowest dry weights for culm, leaf, spike, and total dry matter and minimum grain yield and straw yield were obtained from 25% light either alone or in combination with any plant densities indicating the profound influence of light on dry matter production and grain yield of wheat. Therefore, reduced light (up to 25%) and optimal plant density can ensure wheat production without significant yield loss.

However, most tea-workers living in these areas have lower social profiles and, to some extent, are isolated from mainstream society. The tea-workers communities have diverse ethnic backgrounds, mainly from the neighbouring country - India and different parts of Bangladesh. Initially, within the Tea estates, they were settled in housings developed as 'labour lines', and later those areas were modified and expanded by the communities. There are issues related to space crisis, municipal services, and other amenities such as health care and education in their housing areas, but their settlement patterns have inherent traditional features crafted by the vernacular adaptations. This study aims to identify and analyse their settlement areas' ethnographic landscapes and understand the relationships between their housing morphology and socio-cultural beliefs. We have selected three different communities from the three (03) major tea estates, i.e. Lakkatura, Malnichara and Khadimnagar estate. We developed a conceptual framework incorporating principles from ethnographic landscape and spatial morphology. For ethnographic analysis, we have investigated the socio-cultural profiles (including ethnic origin, demography, financial status, community participation and socio-cultural activities), housing policies and vernacular techniques through field surveys and secondary sources. For morphological analysis, we have adopted McCartney, 2018's framework that helped characterise the study areas' spatial dimensions. Finally, we have developed a typological understanding from the combined approach that outlines the ethnographic landscape of the selected tea-workers communities in Sylhet. Cross-cultural investigations in future can further explore how ethnic landscape changes with migration movements and aid in the planning and policy-making of informal settlements.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121727452","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}

As regulation of land use is largely absent in rural areas, agricultural land use is getting indiscriminately converted into non-agricultural uses. This conversion is threatening agro-based food security of the country in general and of the rural households in particular. Regarding this issue, the current government has emphasized the rural homestead as a ‘production unit’ of agro-farming. As an important source of food and nutrition, homestead farming is an integral part of rural settlements where women play a vital role. However, in most of the cases, it is done in an un-integrated and rudimentary manner. As a result, they are unable to yield the maximum from homestead farming. In this context, the research focuses on designing integrated homestead agro-farming based on case studies of two homesteads of a typical village in Batiaghata, Khulna. With an exploratory approach the research methodology is designed with a three-stage framework. Stage I includes investigation of the categories and needs of agro-products focusing on the role of women in production, processing, management and consumption; Stage II includes exploration of existing spatial-morphological patterns and extent of different types of agro-farming; while Stage III includes development of design schemes for integrated homestead agro-farming. Based on the triangulation of findings, this research contributes strategic physical-spatial design considerations for integrated homestead agro-farming towards ensuring household food security in a socially sustainable and agro-ecologically resilient manner.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128668704","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}

Co-production within the community becomes successful when the community people lead their processes themselves. Through this theme, the communities can enhance their capacity to respond constructively to future problems. Besides, community people, the government, and other organizations play important roles in regulating, financing, and managing the whole process, being potential actors. Slowly, a transformation is taking place in the relationships between the stakeholders—that is, being equal partners in development. This type of relationship strengthens the sustainability of community development initiatives. In some cases, the application of co-production at the grassroots for a better life has encountered numerous challenges limiting participation at various levels. Our study aims at exploring the concept of co-production in housing scenarios, identifying the outcomes of this concept by indicating active roles encountering diverse ways that actors and participants may face challenges to make it successful in the housing process. This paper also focuses on finding out the benefits and drawbacks of co-production in housing and the effectiveness of management policies in the context of Bangladesh. For achieving these objectives, an effective literature review of the existing knowledge on this theme of “Co-Production” has been followed as the study methodology. The results from this study depict that co-production within a community can be an alternative approach to addressing the housing issues of the underprivileged community of society. Although having the challenges of socio-economic and political dynamics, a flexible participatory approach to co-production can be successful in Bangladesh, with an appropriate management policy undertaken by the stakeholders.","PeriodicalId":408769,"journal":{"name":"Khulna University Studies","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131251233","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}
