Introduction The main objective of the Consultancy Services is to assist the Government of Bangladesh in preparation of detailed engineering design and detailed environmental studv for the proposed new road (NHBNR) connecting Nalka-Hatikamrul and Bonpara/Ahmedpur. This report includes all findings and assessments with respect to the environmental issues related to NHBNR. It also elaborates an Environmental Management Action Plan for the major interventions of this project in order to mitigate, minimiseor to avoid potential environmentalhazards. 1.1 Terms of Reference During its screeningand assessment procedures, the Feasibility Study (CIECC, 1993) has identified many issues relating to engineering and environmentalaspects as needing more detailed investigation during a detailed design phase. Based on this analysis, the ToR.) that relate directly and indirectly to both the EIA and the EMAP are as follows: Scope of Services Taking into account the findings of the feasibility analysis and preliminary engineering, as well as the relevant environmental impact studies, the Consultants shall perform detailed environmental studies, economic analysis, detailed field surveys, surface and subsurface investigation, including specific soils and materials investigations, laboratory testing and related works, and proceed with the detailed design of the road, bridges and other drainage structures. A master plan for environmental mitigation shall be drawn up, and implementationprocedures established. During the course of their services the Consultant was supposed to carry out inter alia, a detailed environmental Study in accordance with World Bank Operational Directive 4.01 and 4.30 for a Category A project. *) Selectedtext. adoptedand modified.where applicable. from ToR providedby the Client.

Vol. 35, 2016, pp. 7-15 ISSN 1023-6104 http://journals.sfu.ca/bd/index.php/UJZRU © Rajshahi University Zoological Society Present status of fish biodiversity and abundance in Shiba river, Bangladesh D.A. 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.

    After the Bangladesh Flood Action Plan: Looking to the Future HUGH BRAMMER*

    research paper After the Bangladesh Flood Action Plan: Looking to the future HUGH BRAMMER* 37 Kingsway Court, Hove, East Sussex BN3 2LP, UK The main objectives of the Bangladesh Flood Action Plan (FAP), to protect the country from river floods, were not achieved, for several political, economic and institutional reasons. Demographic and economic changes in the following 20 years have increased Bangladesh’s exposure to damaging floods. The country’s newly elected government is committed to providing flood protection and surface-water irrigation as a means to achieve national foodgrain self-sufficiency. Therefore, the feasibility and affordability of comprehensive flood and water management systems need to be re-examined. The technical assessment must take into account the finding that severe floods in Bangladesh are caused mainly by heavy rainfall within Bangladesh as well as the increased flood and cyclone risks associated with global warming. An institutional assessment should examine practical means to overcome governance constraints and to increase local responsibility for managing flood protection and irrigation projects. If such projects cannot be provided, alternative measures must be sought to provide security for lives, livelihoods and economic production. These could include ‘flood-proofing’ urban and rural settlements, development of improved crop varieties, and more efficient use of irrigation and fertilizers. Measures to expand other sectors of the national economy would also be needed to generate the exports and incomes required to purchase increased food imports. Keywords: Bangladesh; floods; flood protection; irrigation; polders 1. Introduction 1.1. Looking back Bangladesh has changed greatly since the Flood FAP was formulated at the request of the Govern- Action Plan (FAP) was conceived 20 years ago.

(August 2007) Stephanie Kimberly Rice, B.S., The University of Mississippi Co-Chairs of Advisory Committee: Dr. Beth L. Mullenbach Dr. Wilford D. Gardner An examination of suspended sediment concentrations throughout the Ganges- Brahmaputra River System was conducted to assess the spatial variability of river sediment in the world’s largest sediment dispersal system. During the high-discharge monsoon season, suspended sediment concentrations vary widely throughout different geomorphological classes of rivers (main river channels, tributaries, and distributaries). An analysis of the sediment loads in these classes indicates that 7% of the suspended load in the system is diverted from the Ganges and Ganges-Brahmaputra rivers into southern distributaries. Suspended sediment concentrations are also used to calculate annual suspended sediment loads of the main river channels. These calculations show that the Ganges carries 262 million tons/year and the Brahmaputra carries 387 million tons/year.

Hundred fishermen were surveyed randomly with a structured questionnaire. The livelihood status of fishermen was studied in terms of age, family, occupation, education, housing and health condition, credit and income. It was found that most of the fishermen were belonged to the age groups of 20-35 years (50%) represented by 85% Muslims. Majority of them (62%) lived in joint family and average household size was 6-7 people. Educational status revealed that 66% were illiterate. Fishermen houses were found to be of two types namely semi-constructed and unconstructed and among them 77% houses were connected with electricity. About 85% fishermen were landless represented by 95% rearing livestock. Regarding health and sanitation 85% fishermen used sanitary latrines. About 83% fishermen were solely depends on fishing and annual income of 50% fishermen was 50,000 to 60,000 TK.
