In this study the effectiveness of Command Area Development Project (CADP) was investigated. Hydraulic, agricultural and institutional aspects were considered for this purpose. The impacts of CADP on the performance of the project were assessed by comparing the values of selected indicators for the post and pre conditions of CADP considering all the factors mentioned above. The hydraulic indicators were used to compare the relative water supply and water level for some selected canals under pre (1997) and post (2007) CADP condition. The agricultural indictors directly reflect irrigated agricultural system. Irrigated area, yield and production have been used as agricultural

  • 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.

Abu Bakar Siddique, Muhammad Afzal Hussain, Fawzia Adib Flowra, Mohammad Manjurul Alam*1 Department of Fisheries, University of Rajshahi, Rajshahi 6205, Bangladesh. Abstract: The research was carried out to enlist the fish species diversity along with diversity indices Article history: Received 2 July 2016 of existing fish species of Chalan Beel, Bangladesh. During the study, a total of 78 fish species Accepted 21 September 2016 including 69 native and 9 exotic fish species were recorded belonging 10 orders and 26 families. The Available online 25 October 2016 values of Shannon-Weiner diversity index (H') indicated a good spread of fish population in Chalan Beel although the number of species was not found satisfactory. The degradation of water quality Keywords: due to domestic discharges, jute rotting, excessive usage of agro-chemicals, indiscriminate fishing Fish Fauna Shannon-Weiner activity etc. were revealed as the causes of declining the fish diversity of this Beel. The Margalef’s Margalef’s richness richness index (d) expressed the species richness of Chalan Beel that started in July by joining new Pielou’s index fish population with the existing fish species and reached gradually highest in November after breeding. Pielou’s index (J) showed the equal distribution pattern of fish species throughout the sampling area indicating a stable but incompatible habitat for existing fish species.

    BAUET JOURNAL Published by Bangladesh Army University of Engineering & Technology (BAUET) Journal Homepage:http://journal.bauet.ac.bd/ Assessment of Heavy Metal Contamination in the Sediment of Gumani River, Bangladesh Md. Raquibul Hasan1, Niloy Kumar Shil2, Md. Mahfuzul Haque3 1,2,3Department of Civil Engineering, Faculty of Engineering and Technology, Pabna University of Science and Technology, Pabna-6600, Bangladesh Abstract: Gumani River is a typical river in Pabna, Bangladesh. It has been suffering an increasing environmental pressure due to the rapid development of population, social-economy and urbanization as well as a long-term over-cultivation. The present study was conducted to investigate heavy metals in the sediment samples of the Gumani river. Samples were collected from five different sampling locations and were analyzed for Pb, Cd, Cr, Mn, and As by atomic absorption spectrophotometer. The observed order of heavy metal concentration in sediments was Mn>Pb>Cd>As>Cr in mg/kg. The concentrations of heavy metals (Pb, Cd, Cr, Mn, and As) in water were found lower than the permissible level. Using advanced statistical techniques and different pollution indices, the ecological risk has been analyzed to find out the sediment contamination in the Gumani River system. According to the geo-accumulation index (Igeo), Cd might exert a moderately hazardous influence. The pollution load index (PLI) assessment suggested that the sediment samples are not contaminated. Though in the study area, there is a low presence of heavy metals, proper management and monitoring are needed to maintain the ecosystem of the river and the surrounding areas. Keywords: Heavy metals; Sediments; Ecological Impact; Gumani River; Pollution Introduction: Rivers are one of the most important natural resources on earth [1]–[3].

  • Status and Decline Causes of Fishing Activities of the Baral River, Natore, Bangladesh
    J. Sci. Foundation, 9(1&2): 115-124, June-December 2011 ISSN 1728-7855 STATUS AND DECLINE CAUSES OF FISHING ACTIVITIES OF THE BARAL RIVER, NATORE, BANGLADESH *F. A. Flowra, M. A. Islam, S. N. Jahan, M. A. Samad, M. M. Alam ABSTRACT The present investigation is a humble attempt to explore fishing techniques of the River Baral from November 2010 to May 2011. Different fish capture methods, fishing gears and crafts that were usually used in the study area have been provided. Hand fishing, cloth fishing, bait fishing and fishing by dewatering were also observed. Causes of habitat degradation and changes of natural habitat and declination of fishes were also observed. Some problems of the fishing community of the study area were also identified. A few policy recommendations have been given in the concluding chapter which may have some positive implication on the life and living of the fishermen in Bangladesh in general and the Baral basin in particular. Keywords: Gears, Crafts, Spears, Hook and lines, decline causes INTRODUCTION River plays an important role in the life and living of the people of a country specially the fishermen. These are also important in terms of huge fisheries resources and other purposes of navigation, irrigation and domestic uses. A single river possess different name at different places, even a five or six km segment has a different name upstream or downstream. Also a single name is used for different rivers in different locations (Alam and Chowdhury, 2006). Bangladesh has vast inland open water (4024934 ha) which is contributing 35.53% of total fish capture.
