  • Information Sheet on Network Sites
    Site Information Sheet V1 Information Sheet on Flyway Network Sites Notes for compilers: The management body intending to nominate a site for inclusion in the East Asian - Australasian Flyway Site Network is requested to complete a Site Information Sheet. The Site Information Sheet will provide the basic information of the site and detail how the site meets the criteria for inclusion in the Flyway Site Network. The Site Information Sheet has been divided into two sections. Part 1 (Section 1-14) seeks basic information on the site and it is essential that it be completed. Part 2 seeks additional information and is optional. The Site Information Sheet is based on the Ramsar Information Sheet. If the site proposed for the Flyway Site Network is an existing Ramsar site then the documentation process can be simplified. In this case the National Government Partner need only send a copy of the existing sheets with additional details on Question 1 and 10 of the Flyway Site Information Sheet. Once completed, the Site Information Sheet (and accompanying map(s)) should be submitted to the Flyway Partnership Secretariat. Compilers should provide an electronic (MS Word) copy of the Information Sheet and, where possible, digital copies of all maps. Part 1: Essential Information 1. Name and contact details of the compiler of this form: The full name, institution/agency, and address of the person(s) who compiled the SIS, together with any telephone and fax numbers and e-mail address. i.

    Bangladesh]. Fish. Res., 14(1-2), 2010: 103-114 Co-management approach on fisher group: A case study on Ramsar site, Tanguar haor in Bangladesh 1 2 Pulakesh Mondal*, Marion Glaser , Ainun Nishat and Annette Breckwoldt University or Bremen, Bremen, Germany. 1ZMT, Bremen, Germany 'IUCN Bangladesh orrice, Dhaka, Bangladesh *Corresponding author & present address: i\ssistant Chier, J\'\inistry or Fisheries and Livestock, Bangladesh Secretariat, Dhaka 1000, Bangladesh. 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).

  • A Study on Climate Change Impact on the Livelihoods of the People in Tanguar Haor, Bangladesh
    A STUDY ON CLIMATE CHANGE IMPACT ON THE LIVELIHOODS OF THE PEOPLE IN TANGUAR HAOR, BANGLADESH Muhammad Mizanur Rahaman*, Kamrul Islam Sajib and Intekhab Alam Department of Civil Engineering, University of Asia Pacific, House 8, Road 7, Dhanmondi, Dhaka -1205, Bangladesh Fax: +88029664950 Email: [email protected]; [email protected] Email: [email protected] Email: [email protected] *Corresponding author Abstract Bangladesh is widely recognized as one of the most climate vulnerable countries in the world. Previous studies reveal that Surma-Kushiyara river system known as haor basin is projected to be under additional stress due to climate induce changes in temperature and rainfall pattern. Tanguar haor which is located in the north-eastern region of Bangladesh is characterized by large round shaped floodplain depressions and marshy lands. This research focuses on the climate change impacts on the environment, water resources, flood, fisheries, cropping patterns etc. that effects the livelihoods of the people living in the Tanguar haor area. Primary data has been collected through field level questionnaire, key informant interviews and also from various government and non-governmental agencies. For secondary data source, peer-reviewed articles, a wide range of books, research documents and online databases have been reviewed. This paper tries to grasp and analyze the ongoing problems, with main concentration on climate change impacts on the livelihood of Tanguar haor people. This study reveals that the rainfall of Tanguar haor is decreasing, which affects the crops production and fisheries. This study also shows that the average temperature is rising, consequently, drought is frequent in this area which negatively affects the crops production in Tanguar Haor area.

  • Status and Distribution of the Endangered Baer's Pochard Aythya Baeri in Bangladesh
    FORKTAIL 28 (2012): 57–61 Status and distribution of the endangered Baer’s Pochard Aythya baeri in Bangladesh SAYAM U. CHOWDHURY, ALEXANDER C. LEES & PAUL M. THOMPSON Continued declines in the now endangered Baer’s Pochard Aythya baeri imply that this species may well be entering a downward spiral towards global extinction. Knowledge of the drivers of this decline remain fairly anecdotal and even basic data on population trends are hard to come by given the species’s similarity to other diving ducks. We conducted a review of past records of Baer’s Pochard in Bangladesh, given concerns over the reliability of some past counts, to determine the true magnitude of recent declines, and also present counts from targeted surveys in Bangladesh in the 2010–2011 winter in addition to some basic autecological data. We conclude that several of the high counts from the period 1990–2005 may have been in error, but even accounting for these, the population has declined nationally by 99% in just two decades. INTRODUCTION survey methodology, field descriptions and in rare cases photographic documentation. We treated older records as reliable Baer’s Pochard Aythya baeri is a globally threatened diving duck if the observers were known to be experienced surveyors with which breeds in Russia and north-eastern China and winters mainly previous experience of identifying this species. Some AWC records in eastern and southern mainland China, India, Bangladesh and were treated as unreliable if experienced observers, listed as present, Myanmar. It was uplisted from Vulnerable to Endangered on the were subsequently found not to have participated in the counts.
