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. -

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.

Tanguar Haor in Bangladesh
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). -

Therefore, it is important to take practical disaster mitigating measures which meet the local vulnerability conditions of the region. Designating Bangladesh as a research zone, this research aims to propose measures for strengthening the disaster mitigating system tailored to the region starting from identifying the characteristics of the disaster risk threatening the country. To this end, we identified the country’s natural and social characteristics first, and then analyzed the risk challenges and their background as the cause to create and expand the water-related disasters. Furthermore, we also analyzed the system -

Saifullah Bin Aziz a, Neaz A. Hasan b, Md. Mostafizur Rahman Mondol a, Md. Mehedi Alam b, Mohammad Mahfujul Haque b,* a Department of Fisheries, University of Rajshahi, Rajshahi, Bangladesh b Department of Aquaculture, Bangladesh Agricultural University, Mymensingh, Bangladesh ARTICLE INFO ABSTRACT Keywords: This study evaluates changes in fish species diversity over time in Hakaluki Haor, an ecologically critical wetland Haor in Bangladesh, and the factors affecting this diversity. Fish species diversity data were collected from fishers using Fish species diversity participatory rural appraisal tools and the change in the fish species diversity was determined using Shannon- Fishers Wiener, Margalef's Richness and Pielou's Evenness indices. Principal component analysis (PCA) was conducted Principal component analysis with a dataset of 150 fishers survey to characterize the major factors responsible for the reduction of fish species Climate change fi Anthropogenic activity diversity. Out of 63 sh species, 83% of them were under the available category in 2008 which decreased to 51% in 2018. Fish species diversity indices for all 12 taxonomic orders in 2008 declined remarkably in 2018. The first PCA (climatic change) responsible for the reduced fish species diversity explained 24.05% of the variance and consisted of erratic rainfall (positive correlation coefficient 0.680), heavy rainfall (À0.544), temperature fluctu- ation (0.561), and beel siltation (0.503). The second PCA was anthropogenic activity, including the use of harmful fishing gear (0.702), application of urea to harvest fish (0.673), drying beels annually (0.531), and overfishing (0.513). -

Pakistan's Progress
39 Pakistan's Progress By Guy Mountfort In the short space of twelve months Pakistan has laid wide-ranging plans for conserving her wildlife, hitherto completely neglected. On the recommenda- tion of two World Wildlife Fund expeditions, led by Guy Mountfort, an international WWF trustee, two national parks and several reserves are being created which should give Pakistan a last chance to save the tiger, the snow leopard and several other seriously threatened mammals and birds. NTIL very recently wildlife conservation in Pakistan was non- U existent; today the situation is extremely encouraging. Under the direction of President Ayub Khan, most of the recommendations in the report of the 1967 World Wildlife Fund expedition have already been implemented, and a number of the proposed new wildlife reserves are now in being. A wildlife committee (in effect a Government Commission) has been set up under the distinguished chairmanship of Mr. M. M. Ahmad, Deputy Chairman of the Central Government Planning Commission, to create a permanent administrative framework for the conservation and management of wildlife and habitats, and two sub-committees are studying technical, educational, legal and administrative requirements. After submitting detailed reports and recommendations to the President in the spring of 1970, the committee will be replaced by a permanent wildlife advisory body to co-ordinate future planning. Responsibility for the management of wildlife resources has been given to the Department of Forests. Forest Officers are to be given special train- ing in wildlife ecology and management, and the first trainees have just completed courses in the United States. Meanwhile, a post-graduate curriculum in wildlife management is in preparation at the Forest Institute at Peshawar, to which Major Ian Grimwood has been seconded by FAO.
