Introduction 1.1 Background The Roads and Highways Department has undertakenthe Detailed Engineering,Preparation of Bid Documents,Environmental Impact Assessmentand ResettlementPlan of the Nalka - Hatikamrul - Bonpara (NHB) New Road under financing of the IDA. The contract for detailed engineering design based on a comprehensiveanalysis of the possible environmental impacts*)and elaboration of an EnvironmentalManagement Plan (EMAP) was awarded by the RHD to DHV Consultants BV (The Netherlands), in association with Consulting Engineering Services Pvt Ltd (India), DevelopmentDesign Consultants Ltd (Bangladesh)and Desh Upodesh Ltd (Bangladesh). Prior to the detailed engineering design a preliminarybaseline study was carried out in 1993 to test the feasibility of the project. The former study also incorporated the assessment of the impact of four alignment choices, along which the baseline conditions were recorded. Due to time and personnel constraints, the features described and the assessment relied mainly on secondary sources with some field work inputs (CIECC,Vol.2, 1993). The Feasibility Study recommendeda more detailed field investigation,including a comprehensiveEIA and a mitigation plan. 1.2 Terms of Reference and Objectives A detailed environmental study of the planned construcition,concerning environmental and resettlement issues, to be undertaken in accordancewith WB Operational Directives4.30 and 4.01, is included in the ToR and constitutes an integrated part of the detailed engineering design. This baseline survey is designed to meet the requirements as basis for a comprehensive EIA and elaboration of an Environmental Management Plan, including the ToR for a Resettlement Action Plan. Because of the planned construction of NHB new road a variety of ecologically important habitats will be affected, and land will have to be expropriated and people displaced. The Project is therefore likely to cause serious environmental,social and economic problems. It is the policy of the WB to absolutely minimise both adverse environmental effects and the involuntary resettlement of people. As for the first, the Project needs to ensure that the key physiographic and biological components will maintain to the maximum possible their ecological function, and wherever possible, to incorporateenvironmental enhancement features in the Project's design. As for the latter, the Project should be designedto provide the project affected persons (PAPs) with the means to improve, or at least restore, their former living standards, earning capacity and production levels. Where the displacement of PAPs can not be avoided a detailed resettlement plan, includinga timetable and budget, is required. *) TheProject is classifiedby WORLDBANK as a CategoryA project,requiring a full EIA as partof fundingconditions EnvironmentalBaseline Survey 3 October 1996 C: \ EIA \ BASELINE.DOC DHV Consultants BV Followingthis overall rationale,the ecologicalbaseline survey serves the following objectives: - providing an overview of the bio-physicalcharacteristics of the ProjectArea; - describe the ecological functionof key habitats, refenringto their biodiversityvalues; - analyse the particular hydraulic features of the floodplain, and identify measures to mitigate the effects of floodingand drainage associatedwith thteNHBNR project; - describing the nature and uses of the natural resources, and how theses uses are associated with the PAP; - investigating key habitats with respect to their sensitivity towards environmental impacts, particularly to define the degree of susceptibilityagainst excavationactivities; - analyse the biological and ecological properties of plant and animal species that will, in one way or another, play a role in implementingthe EMAP. The socio-economicsample survey serves the purposes of. - providing a broad overview of the characteristics of direct PAPs, their numbers and composition,their occupation,income, assets and resourcesetc; - estimatingthe magnitudeof displacementof people,how many households are affected; - being a directive for the proper planning, budgeting and implementationof the PAP census to be done by the NGO to be appointed; - determiningtypical PAP categories for RAP implementation; - to make a first assessment of measures to be taken to off set resettlement draw backs faced by the PAPs and to group these measures into packages; - providing the elementary data on households,land and structures for the preparationof a cost estimate for the RAP. 1.3 Scope of Survey The scope of the baseline survey undertaken corresponds to the purpose and the objectives of this Project as explained above. ' The ecological survey data have been compiled to serve as basis for drafting the Environmental Management Plan EMAP, which delineates, among others, the proposed mitigation measures and environmentalmonitoring activities.Part of the EMAP is linked to the detailed engineering

Khanom, T Khatun, M.A.S. Jewel*, M.D. Hossain and M.M. Rahman Department of Fisheries, University of Rajshahi, Rajshahi 6205, Bangladesh Abstract: The study was conducted to investigate the abundance and present status of fish biodiversity in the Shiba river at Tanore Upazila of Rajshahi district, Bangladesh. The study was conducted from November, 2016 to February, 2017. A total of 30 species of fishes were recorded belonging to nine orders, 15 families and 26 genera. Cypriniformes and Siluriformes were the most diversified groups in terms of species. Among 30 species, nine species under the order Cypriniformes, nine species of Siluriformes, five species of Perciformes, two species of Channiformes, two species of Mastacembeliformes, one species of Beloniformes, one species of Clupeiformes, one species of Osteoglossiformes and one species of Decapoda, Crustacea were found. Machrobrachium lamarrei of the family Palaemonidae under Decapoda order was the most dominant species contributing 26.29% of the total catch. In the Shiba river only 6.65% threatened fish species were found, and among them 1.57% were endangered and 4.96% were vulnerable. The mean values of Shannon-Weaver diversity (H), Margalef’s richness (D) and Pielou’s (e) evenness were found as 1.86, 2.22 and 0.74, respectively. Relationship between Shannon-Weaver diversity index (H) and pollution indicates the river as light to moderate polluted.

  • Historical Geography and Demography of Colonial Northern Bengal
    Chapter I Historical Geography and Demography of Colonial Northern Bengal The present chapter seeks to historicize the geographical transformations and ecological vulnerabilities during the colonial periods in northern Bengal. The chapter also intends to explain the demographic transformations of northern Bengal shaped by the environmental factors and natural disasters occurred during the period of the study. Apart from the geographical and demographical changes the chapter will also focus on the political construction of the northern Bengal districts which had gone through several territorial and administrative adjustments and transfers of lands among each other even in the first half of the twentieth century. In order to analyse the geographical characteristics, the river system, change of river course and formation of new lands seemed to be the most decisive factor for the geographical construction of the region. Northern Bengal had a great variety of topographical structures which extended from the Darjeeling Himalayan ranges to the riverine inundated agricultural tracts. Niharranjan Ray, while describing the northern boundary of Bengal, has argued that the north of Bengal is bounded up by the Sikkim and the snowy Himalayan peak of Kanchenjungha below which there are Jalpaiguri and Darjeeling districts.1 The districts of Jalpaiguri, Darjeeling and the State of Cooch Behar were overwhelmingly populated by the hilly tribes viz. Lepcha, Limbu, Koch, Rajbanshi, and Bhutia; and the north-eastern boundary in the ancient time was extended up to the Brahmaputra river which demarcated the eastern and western boundary of Pundrabardhan and Kamrup State respectively.2 H. Blochmann has mentioned about the five ‘districts’ of Bengal during pre-medieval period viz.

Copyright © Strategic Foresight Group 2013 ISBN 978-81-88262-19-9 Design and production by MadderRed Printed at Mail Order Solutions India Pvt. Ltd., Mumbai, India PREFACE At the superficial level, relations between India and Bangladesh seem to be sailing through troubled waters. The failure to sign the Teesta River Agreement is apparently the most visible example of the failure of reason in the relations between the two countries. What is apparent is often not real. Behind the cacophony of critics, the Governments of the two countries have been working diligently to establish sound foundation for constructive relationship between the two countries. There is a positive momentum. There are also difficulties, but they are surmountable. The reason why the Teesta River Agreement has not been signed is that seasonal variations reduce the flow of the river to less than 1 BCM per month during the lean season. This creates difficulties for the mainly agrarian and poor population of the northern districts of West Bengal province in India and the north-western districts of Bangladesh. There is temptation to argue for maximum allocation of the water flow to secure access to water in the lean season.

  • Fish Assemblage and Structure As Well As Hydrological Parameters at Karatoya Fish Sanctuary, Panchagarh, Bangladesh
    Iranian Journal of Fisheries Sciences 18(1) 140-162 2019 DOI: 10.22092/ijfs.2018.117727 Fish assemblage and structure as well as hydrological parameters at Karatoya Fish Sanctuary, Panchagarh, Bangladesh Md. Rashidul I.1*; Md. Jewel M.1; Shirin S2. Received: August 2016 Accepted: February 2017 Abstract Spatiotemporal variations in fish assemblage structure was studied from January to December 2015 in order to understand the impacts of the sanctuary on ichthyo-faunal diversity and to determine the indices and major hydrological factors in six sampling stations of Karatoya Fish Sanctuary sectioned in the River Karatoya. A total of 69 fish species were obtained from this sanctuary including 21 threatened species where Aspidoparia jaya, Pethia ticto, Puntius sophore, Canthophrys gongota and Barilius barna were the major contributory species (>4.17%) both in space and time. The uppermost species richness and abundance were viewed in January and lowest in May. Based on analysis of similarities (ANOSIM), fish assemblages were significantly different in all stations (p<0.001, R=0.15) and months (p<0.001, R=0.62). Through two-dimensional nonmetric multidimensional scaling (nMDS) and cluster analysis based on Bray-Curtis similarity index, assemblages were alienated into two groups at a value of 42% and 28% partition for station and month, respectively. Canonical Correspondence Analysis (CCA) recognized considerable relations between the number -1 Downloaded from jifro.ir at 2:44 +0330 on Sunday September 26th 2021 of fishes and hydrological parameters where dissolved oxygen (mg L ) and water temperature (ºC) were the main leading factors in shaping the fish assemblage structure.
