Hasibur Rahman Shahriar Rahman Marufa Sultana M.M. Abdullah-Al-Mamun Mohammad Abul Kalam Azad Alison Darcy Md. Wasim Newaz vii Preface Wetlands are amongst the Earth's most productive ecosystems. In Bangladesh these are of great importance because of the extensive food webs and rich biodiversity they support. In the past, wetlands have been undervalued. However, in recent times, awareness increases of the fact that natural wetlands provide many services toward mankind through various functions, products e.g., fish, fuelwood, timber, rice, and attributes i.e., biodiversity, aesthetic beauty, cultural heritage and archaeology. Bangaldesh's most important freshwater wetlands occur in the Hoar Basin apart from the Ganges- Brahmaputra delta, which is low lying plains in eastern Mymensingh and western Sylhet Divisions, in the north-eastern part of the country. Tanguar haor is located in two Upazillas (sub-districts) namely Tahirpur and Dharmapasha of Sunamganj district in Sylhet Division. The Tanguar Haor basin, which is an area of 10,000 hectares of land, also supports about 60,000 populations with its resources. Tanguar haor has outstanding conservation value, being a natural freshwater wetlands in the country,seasonally harbouring up to 60,000 migratory waterfowl along with many resident birds, more than 140 fish species and last vestiges of swamp forest. But the floral and faunal diversity of Tanguar Haor is under extensive threat because of unsustainable use of resources. In 1999, Government of Bangladesh declared the Tanguar Haor Basin as an “Ecologically Critical Area” to highlight its ecological importance and to monitor its environmental quality. In 2000, the haor basin was declared as the country's second RAMSAR site – wetland of international importance. With the declaration of Tanguar Haor as a RAMSAR site, government has its commitment to preserve the ecosystem and floral and faunal diversity including its migratory birds from illegal hunters. Government developed a comprehensive management plan – the Tanguar Haor Management Plan (THMP), which envisaged 'wise use' of its natural resources vis-à -vas a plan to uplift economic conditions of the local people. Importance were given to aware local community for preserving the natural resources and biodiversity and eventually protect it from degradation and overexploitation. On the above context, IUCN Bangladesh has taken an initiative to carry out this recent study on biodiversity under the project ''Community Based Sustainable Management of Tanguar Haor''. The project is being implemented by the Ministry of Environment and Forest through IUCN Bangladesh Country Office with financial assistance from Swiss Agency for Development and Cooperation (SDC). As an outcome of the project this book is to share information on threatened and most important biodiversity with the local community in Tanguar Haor. This is an expectation of IUCN Bangladesh that the book will be of immense help to monitor changes of important floral and faunal diversity of the Tanguar Haor. We also hope that this book help local people of Tanguar Haor to categorize, understand flora and fauna, watch and take conservation initiatives by stopping overexploitation, hunting, poaching of natural resources. On the other hand, this book will also be a great source of material for the researchers who are currently or in future will continue their study on flora and fauna of Tanguar Haor.

  • 1 Hydrological Impacts of Climate Change on Rice
    Hydrological impacts of climate change on rice cultivated riparian wetlands in the Upper Meghna River Basin (Bangladesh and India) Mohammed M. Rahman a,b,*, Julian R. Thompson b, and Roger J. Flower b a Department of Irrigation and Water Management, Bangladesh Agricultural University, Mymensingh, Bangladesh b Wetland Research Unit, Department of Geography, University College London, London WC1E 6BT, UK * Corresponding author: email [email protected] Tel: +88 01717 825850; Fax: +88 091 61510 Abstract Riparian depressional wetlands (haors) in the Upper Meghna River Basin of Bangladesh are invaluable agricultural resources. They are completely flooded between June and November and planted with Boro rice when floodwater recedes in December. However, early harvest period (April/May) floods frequently damage ripening rice. A calibrated/validated Soil and Water Assessment Tool for riparian wetland (SWATrw) model is perturbed with bias free (using an improved quantile mapping approach) climate projections from 17 general circulation models (GCMs) for the period 2031–2050. Projected mean annual rainfall increases (200–500 mm per 7–10%). However, during the harvest period lower rainfall (21–75%) and higher evapotranspiration (1–8%) reduces river discharge (5–18%) and wetland inundation (inundation fraction declines of 0.005–0.14). Flooding risk for Boro rice consequently declines (rationalized flood risk reductions of 0.02–0.12). However, the loss of cultivable land (15.3%) to increases in permanent haor inundation represents a major threat to regional food security. Keywords haor wetlands; Boro rice; floods; Bangladesh; climate change; SWAT 1 Introduction The potential consequences of climate change on hydrological processes and associated sectors such as water resources, agriculture, aquatic ecology and human livelihoods have been extensively documented (e.g.

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.

E-mail: pulak76((:t!gmail.com Abstract In Bangladesh, wetlands are managed through leasing system traditionally from time immemorial. Recently the Government accepted co-management approach for wetland fisheries management and this approach is being practiced in few wetlands for maximize revenue income. i\ study was carried out to evaluate trend and impact of co-management in Tanguw· haor (a Ramsar site wetland) on fisheries resources and livelihood of resident people in the immediate vicinity of the wetland. In Tanguar haor, conflict between leaseholders and the local community was a common phenomenon in the past. Since 2003 the district administration of Sunamganj has been managing the vast wetland resources, however, local people participation was ignored in haor management system. Average monthly fish catch of fishermen increased by 17°/iJ after introduction of co­ management system and 7 fish species reappeared after introduction of co-management. Average monthly volume of fish catch has increased from 70 kg to 87 kg. A well-defined management structure has been developed for integration of all people of Tanguar haor which vvould enable them to raise voice jointly and influence policy in their favour. Key words: Co-management, \\letland, Fishers Introduction \X!etlands of Bangladesh are rich in biodiversity and have great ecological, economic and social values in ensuring livelihood security of millions of poor people particularly fisher community in Bangladesh (Nishat 1993).

Yeasmin, M.S. Reza, F.H. Shikha, M.N.A. Khan and M. Kamal Department of Fisheries Technology, Faculty of Fisheries, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh Abstract: The study was conducted to evaluate the influence of formalin on the quality changes in rohu fish (Labeo rohita, Hamilton) during ice storage condition. There are complaints from the consumers that the fish traders in Bangladesh use formalin in fish imported from neighboring countries to increase the shelf life. On the basis of organoleptic characteristics, the formalin treated fishes were found in acceptable condition for 28 to 32 days in ice as compared to the control fish, which showed shelf life of 20 to 23 days. Bacterial load in formalin treated fish was below detection level even after 16 days of ice storage whereas bacterial load was significantly higher in fresh rohu stored in ice and at the end of 24 days of ice storage. NPN content was increased gradually in fresh rohu with the increased storage period in ice. On the other hand, NPN content of formalin treated rohu decreased gradually during the same period of storage. Protein solubility in formalin treated fish decreased significantly to 25% from initial of 58% during 24 days of ice storage as compared to 40% from initial of 86.70% for control fish during the same ice storage period.
