Studies were conducted for a period of 6 months Accepted: 26 August 2018 from July to December 2016. Focus group discussions (FGD), questionnaire interviews (QI) and key informant interviews (KII) were done to collect appropriate data from the local fishers and resource persons. A total of 62 species of fish and shellfish from 23 families were found in the river and 9 species disappeared in last 10 years. The species availability status was Keywords remarked in three categories and obtained as 14 species were commonly available, 28 species were moderately available and 20 species were rarely available. The highest percentage of Aquaculture Biodiversity fishes was catfishes (24.19%). There was a gradual reduction in the species diversity from Fishes and shellfishes previous 71 species to present 62 species with 12.68% declined by last 10 years. -
Mapping Exercise on Water- Logging in South West of Bangladesh
MAPPING EXERCISE ON WATER- LOGGING IN SOUTH WEST OF BANGLADESH DRAFT FOR CONSULTATION FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS March 2015 I Preface This report presents the results of a study conducted in 2014 into the factors leading to water logging in the South West region of Bangladesh. It is intended to assist the relevant institutions of the Government of Bangladesh address the underlying causes of water logging. Ultimately, this will be for the benefit of local communities, and of local institutions, and will improve their resilience to the threat of recurring and/or long-lasting flooding. The study is intended not as an end point, but as a starting point for dialogue between the various stakeholders both within and outside government. Following release of this draft report, a number of consultations will be held organized both in Dhaka and in the South West by the study team, to help establish some form of consensus on possible ways forward, and get agreement on the actions needed, the resources required and who should be involved. The work was carried out by FAO as co-chair of the Bangladesh Food Security Cluster, and is also a contribution towards the Government’s Master Plan for the Agricultural development of the Southern Region of the country. This preliminary work was funded by DfID, in association with activities conducted by World Food Programme following the water logging which took place in Satkhira, Khulna and Jessore during late 2013.

Aquatic Ecology and Dangerous Substances: Bangladesh Perspective
Diffuse Pollution Conference Dublin 2003 8C Ecology: AQUATIC ECOLOGY AND DANGEROUS SUBSTANCES: BANGLADESH PERSPECTIVE Institute for Environment and Development Studies 5/12-15, Eastern view (5th floor), 50, D.I.T Extension Road, Dhaka -1000, Bangladesh. E-mail: [email protected] ; Phone: +880 2 9354128 ; Fax: +880 2 8315394 Bangladesh had always been predominantly and agricultural based country and in early days pollution was never even felt in this region. Since early sixties, of necessity, industries of various kinds started to spring up slowly. It appears in a survey that ecological imbalance is being caused continuously due to discharge of various industrial wastes into air and water bodies. It has also been found that the intensity of pollution caused by the factories and industrial units depend on their type, location, raw materials, chemical effects, production process and discharge of gaseous, liquid and solid pollutants to the natural environment. All of Bangladesh's sewage and industrial wastes are flushed directly into Ganges and Brahmaputra Rivers. There are wide spread fears that as the region develops in industrial infrastructure, industrial pollution will accelerate, compounding the problems posed by raw municipal wastes. About 900 polluting industries in Bangladesh dispose of untreated industrial wastes directly into rivers, although the effluents contain 10 to 100 times the allowable levels permissible for human health. The Ganges-Brahmaputra delta is the largest delta in the world and the rivers contribute one-third of the global sediment transport to the world oceans. The rivers flow through 10 per cent global population and carry untreated rural, urban, municipal and industrial wastes to the Bay of Bengal. -

With vast low lying areas, Bangladesh is considered as one of the most vulnerable countries in the world to climate change. Strengthening the resilience to climate change is pivotal in all its development and poverty alleviation activities. The city of Khulna, being located in the coastal area of Bangladesh, and influenced by tides from the Bay of Bengal, is highly vulnerable to climate change. The increasing salinity intrusion into the city waters and the anticipated sea level rise might have a major impact on the water resources and the water and drainage infrastructure of the city and its surrounding areas. The city experiences frequent water logging during the rainy season. -

Situation Assessment Report in S-W Coastal Region of Bangladesh
Livelihood Adaptation to Climate Change Project (BGD/01/004/01/99) SITUATION ASSESSMENT REPORT IN S-W COASTAL REGION OF BANGLADESH (JUNE, 2009) Food and Agriculture Organization of the United Nations (FAO) Department of Agricultural Extension (DAE) Acknowledgements The present study on livelihoods adaptation was conducted under the project Livelihood Adaptation to Climate Change, project phase-II (LACC-II), a sub-component of the Comprehensive Disaster Management Programme (CDMP), funded by UNDP, EU and DFID which is being implemented by the Department of Agricultural Extension (DAE) with technical support of the Food and Agriculture Organization (FAO), UN. The Project Management Unit is especially thankful to Dr Stephan Baas, Lead Technical Advisor (Environment, Climate Change and Bioenergy Division (NRC), FAO, Rome) and Dr Ramasamy Selvaraju, Environment Officer (NRC Division, FAO, Rome) for their overall technical guidance and highly proactive initiatives. The final document and the development of the project outputs are direct results of their valuable insights received on a regular basis. The inputs in the form of valuable information provided by Field Officers (Monitoring) of four coastal Upazilas proved very useful in compiling the report. The reports of the upazilas are very informative and well presented. In the course of the study, the discussions with a number of DAE officials at central and field level were found insightful. In devising the fieldwork the useful contributions from the DAE field offices in four study upazilas and in district offices of Khulna and Pirojpur was significant. The cooperation with the responsible SAAOs in four upazilas was also highly useful. The finalization of the study report has benefited from the valuable inputs, comments and suggestions received from various agencies such as DAE, Climate Change Cell, SRDI (Central and Regional offices), and others. -

Mullenbach Wilford D. Gardner Committee Members, Mary Jo Richardson Head of Department, Robert R. Stickney August 2007 Major Subject: Oceanography iii ABSTRACT Suspended Sediment Transport in the Ganges-Brahmaputra River System, Bangladesh. (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. -
