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. -

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 -

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. -

IIFET 2012 Tanzania Proceedings
IIFET 2012 Tanzania Proceedings ECONOMIC INCENTIVE FOR WETLAND BIODIVERSITY AND FISHERIES CONSERVATION: THE CASE OF CHALAN BEEL (WETLAND) Aminur Rahman School of Business Independent University, Bangladesh ABSTRACT Chalan Beel, a wetland situated in the North Western Bangladesh is a very potential wetland with immense biodiversity and fisheries value. Its management problem has engulfed with suggestions ranging from private leasing, joint administration by public representation and government and community based approaches. However, nothing sustainable so far emerged concerning bio diversity and mother fishery conservations. In the midst of this uncertainty an approach based on economic incentives can be a way out to conserve biodiversity. Incentives are placed to influence people’s behavior by making objects more desirable for conservation rather than degrade and deplete it. Economic activities many ways harm biodiversity as it may sometime sounds economically profitable from individual point of view and existence of different failures leading to externalities. Since economic incentives for biodiversity and fisheries conservation can take various forms, the appropriate incentives depend on a wide range of factors, including social, political and economic. Any form of management needs augmentation of clear understanding of right economic signals so that efficient level of resources is utilized. Since the issue is a complex one different incentive have been analyzed with their relevant costs and benefits conducting surveys among the stakeholders where the options based on market based ones have better chance to conserve rare fishery spices and bio diversities rather than using Command and Control ones. For resource valuation Benefit Transfer Method has been used. INTRODUCTION Chalan Beel is one of the largest inland depression of marshy character and also one of the richest wetland areas of Bangladesh. -
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. -
