There will be wide range of vehicles such as two and three axle/ multi axle trucks, bus, car, two-wheeler etc. These type of transportation system are major contributors to air pollution as these emit harmful pollutants which has adverse impact on environment. It is difficult to project air pollution as because pollutant enters the air by different amounts at different times and also varies with places. It is expected that air pollutants which might be discharged by the operations of tenant in the industrial and logistic area would be well controlled and managed by the tenants. For indicative assessment of air quality of the project area, projection has been done for some pollutants due to vehicle emission only. Forecast Area The areas examined to forecast is the project area (Zone 2A and 2B of BSMSN) shown in the Figure 1- 1. The project area is about 1450 acres. At present, it is observed that the concentration of some pollutants such as SO2, NOX, CO, PM2.5, PM10 and SPM are below the allowable limit as per DoE standard (Bangladesh). All the surveyed data are given in the baseline data collection section of main report.

  • Importance of Making More Water Dams and Construction of Concretes River Embankment in Bangladesh to Protect Flood
    IOSR Journal of Environmental Science, Toxicology and Food Technology (IOSR-JESTFT) e-ISSN: 2319-2402,p- ISSN: 2319-2399.Volume 14, Issue 11Ser. I (November 2020), PP 43-53 www.iosrjournals.org Importance of Making More Water Dams and Construction of Concretes River Embankment in Bangladesh to Protect Flood Asaduzzaman1*, Tao Wang2 1Master’s Student and Graduate Research Assistant, State Key Laboratory of Water Resources and Hydropower Engineering Science, Wuhan University, 430072, China 2Associate Professor, School of Water Resources and Hydropower Engineering, Wuhan University, 430072, China *Corresponding author. Mobile: +880-1836928714, +86-16-27013327. E-mail address: Asaduzzaman ([email protected]) Abstract Water is Bangladesh’s blessing and a curse. For nearly half the year, the monsoon rains cause the country’s four major rivers, the Jamuna, Padma, Brahmaputra and Meghna, and their tributaries to swell. Devastating floods are often the consequence. During the rest of the year, the dry season brings almost no rainfall, and droughts threaten the livelihoods of people and the health of the natural environment. Frequent and widespread flooding is a major problem in Bangladesh, which is a Rangpur, Bogra, Shirajganj, Rajbari Region. The problem is caused mainly by the Jamuna River and sudden coming floodwater from India through Brahmaputra whose erratic riverbank erosion has been leading to the general widening of channels and large-scale instability of riverbanks. Both the flooding and erosion in the river valley can be tackled only through an adaptive response that includes the use of structural protection systems such as making water dams and strong river embankment. A practicability study in this paper was led for riverbank protection works and an increasing number of dams are also discussed.

  • Sensitive Space Along the India-Bangladesh Border
    THE FRAGMENTS AND THEIR NATION(S): SENSITIVE SPACE ALONG THE INDIA-BANGLADESH BORDER A Dissertation Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Jason Cons January 2011 © 2011 Jason Cons THE FRAGMENTS AND THEIR NATION(S): SENSITIVE SPACE ALONG THE INDIA-BANGLADESH BORDER Jason Cons, Ph.D. Cornell University 2011 Borders are often described as “sensitive” areas—exceptional and dangerous spaces at once central to national imaginaries and at the limits of state control. Yet what does sensitivity mean for those who live in, and those who are in charge of regulating, such spaces? Why do these areas persist as spaces of conflict and confusion? This dissertation explores these questions in relation to a series of enclaves—sovereign pieces of India inside of Bangladesh and vice versa—clustered along the Northern India–Bangladesh border. In it, I develop the notion of “sensitivity” as an analytic for understanding spaces like the enclaves, showing how they are zones within which postcolonial fears about sovereignty, security, identity, and national survival become mapped onto territory. I outline the politics of sensitivity and the production of sensitive space through both historical and ethnographic research. First, I explore the ways that ambiguity and vague fears about security and citizenship emerge as forms of moral regulation within and in relation to the enclaves. Specifically, I interrogate the processes through which information about the enclaves is regulated and policed and the ambiguity, suspicion, and insecurity that emerge out of such practices.

    Bangladesh J. Zool. 45(1): 47-60, 2017 ISSN: 0304-9027 (print) 2408-8455 (online) DIVERSITY OF ICHTHYOFAUNA OF FENI AND MUHURI RIVERS, FENI, BANGLADESH Sumana Yeasmin, Gulshan Ara Latifa and Gawsia Wahidunnessa Chowdhury* Department of Zoology, University of Dhaka, Dhaka-1000, Bangladesh Abstract: Diversity of ichthyofauna of Feni and Muhuri rivers was studied from April, 2015 to March 2016. The selected rivers were surveyed to cover the wet season (April 2015-September 2015) and the dry season (October 2015-March 2016). A total of 65 freshwater fish species belonging to 11 orders, 29 families were recorded from the two rivers. Of the 65 species, 12 species were threatened, and one species was identified as data deficient according to IUCN Bangladesh. Perciformes was recorded as most dominating order (19 species, among the 54 species recorded) in Feni river, whereas the Cypriniformes was recorded as the dominating order (17 species among the 42 species recorded from this river) in Muhuri river. Corica soborna was the most common species with the highest number of individuals in comparison to other fish species recorded from two rivers in both wet and dry seasons. Calculating the Shannon-Weiner and Simpson’s indices of diversity and species evenness, highest number of species and individuals were found in the wet season while minimum in the dry season from both the rivers. Key words: Ichthyofauna, Feni River, Muhuri River, status. INTRODUCTION Bangladesh (between 200 34′N and 260 38′N latitude and between 88001′E and 92041′E longitude in South Asia) is bordered by India to the north, east and west and Myanmar for a small portion in the south-east (Akonda 1989).

  • Hazard EARLY WARNING & Humanitarian Response
    UN World Food Programme Supported by Bangladesh Country Office Disaster Risk Reduction Unit WFP Bangladesh Bulletin Hazard EARLY WARNING & Humanitarian Response Issue 26/ 2007 23 July 2007 HIGHLIGHTS Heavy rains fell throughout the country during the period 17th July to 22nd July. The rains have contributed to localized flash flooding, particularly in the Northeast and Southeast Bangladesh. River levels have risen considerably in the Northeast and Southeast. Five rivers have reached their danger levels as of 22nd July. The rainfall forecast for the next two days shows highest expected rainfall in the Southeast, within the districts of Chittagong, Feni and Noakhali. Rainfall Extremes and Forecast: Between the morning of the 21st and 22nd July numerous locations throughout the country received heavy rain above the threshold for localized flooding; these included Comilla (78 mms), Patualkali (79 mms), Pabna (99 mms), and Rajshahi (105 mms). According to a Bangladesh Meteorological Department/ BMD report issued at 3 pm on 22nd July, more heavy rainfall is likely to occur but will diminish by 25th July. The 3-day forecast (22nd–24th July) shows areas within the districts of Chittagong, Feni and Noakhali in the Southeast are expected to receive cumulative rainfall above 150 mms. Heavy rainfall is expected for the neighboring Indian state of Meghalaya bordering Sylhet in the Northeast of Bangladesh. The same forecast applies to the Indian state of West Bengal, near the area that borders Bangladesh’s districts of Panchagarh and Thakurgaon in the extreme Northwest. Note: Rainfall thresholds for potential localized flooding are 75 mms (24 hours) and 150 mms (72 hours).
