    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.

For detecting trend and change, Pettitt test, standard normal homogeneity test (SNHT), Mann-Kendall test, Spearman’s rank correlation methods have been used. It is observed that within this spectrum of study period, 1992 is detected as yard mark f or change in flow regime. In pre and post change point phases, water levels have reduced by 10.22%, 18.22%, 15.42% and 12.48% during pre monsoon, monsoon, post monsoon and winter periods respectively. Significant trend is detected in mean, maximum and minimum flow character as indicated by Kendall's tau value of MK test e.g. -0.57, -0.62 and -0.48 in the respective parameters. After change point phase water level is reduced but variability of flow is increased from 2.24% to 6.61% for mean flow level, 1.54% to 6.45 % for maximum flow level and 3.24% to 5.78% for minimum flow level. This sort of flow attenuation has fur flung impact on downstream habitat and ecosystem characters.

Satellite image-driven temperature and depth data calibrated with field data were 10 used to analyse fish habitability and the presence of thermally optimum habitable zones in some 11 fishes such as Labeo Rohita, Cirrhinus mrigala, Tilapia fish, Small shrimp, and Cat fishes. The 12 study was conducted both at the water's surface and at the optimum depth of survival. It is very 13 obvious from the analysis that a larger part of wetland has become an area that destroyed aquatic 14 habitat during the post-dam period and existing wetlands have suffered significant shallowing of 15 water depth.

Read Full License Page 1/19 Abstract Assessing sh habitability in pursuance of damming for some selected shes in wetland of Indo- Bangladesh barind tract using hydrological ingredients like hydro-period, water depth, and water presence consistency is major focus of the present study. Rule based decision tree modeling has been applied for integrating aforesaid hydrological parameters to nd out habitat suitability for some selected shes like carp shes, shrimps, tilapia and cat shes both for pre-dam and post-dam periods. From this work it is highlighted that damming has accelerated the rate of wetland deterioration in forms of hydrological ow alteration i.e. inconsistency in water presence has increased, hydro-duration became shortened and water depth has attenuated. From the model it is very clear that a small proportion area was considered to be good sh habitat (16.54–39.90%) in pre-dam period, but after damming almost all parts have become least suitable for sh habitability. Field survey has conrmed that shing quantity, growing rate of shes was higher in pre-dam situation but it is reduced gradually during post-dam period.

Abstract Freshwater fishes are declining rapidly due to their high sensitivity to the quantitative and qualitative alteration of aquatic habitats and India is no exception. The small rivers of this country provide refuge to innumerable fish species with hardly any documentation. This study was directed to assess fish biodiversity with reference to species diversity, phylogenetic diversity and functional diversity of the fish assemblage in three interconnected shallow rivers in the northern part of West Bengal. Sampling was conducted in between September 2007 to August 2011and diversity estimators depict higher species richness and evenness and less dominance during monsoon and autumn with progressive declining trend through winter, spring and summer. The taxonomic and functional diversity also depicted similar trend in relation with total fish catch. However, the average taxonomic distinctness, phylogenetic diversity and functional diversity estimator indicate the inherent taxonomic diversity and functional complementarity of the fish assemblage throughout the year irrespective of total fish catch. This fact signifies the importance of these three interconnected rivers as a precious habitat for indigenous fish species ensuring effective niche segregation and coexistence in a stable way for the resident fish fauna.

Therefore, the present study carried out to assess the degree of encroachment of floodplains and its impact on fish biodiversity and the livelihoods of the neighboring fishing communities. The study covered three beels of Naogaon district through remote sensing image interpretation and PRA techniques. The study used three dates remote sensing images and field data which supplemented with the secondary data from diverse origins. Data collected through the recalling method, personal interview with a structured questionnaire and livelihood analysis of fishermen and non-fishermen group living around the beels. The data interpretation showed the water area reduced by 80% from 1981 to 2016 in dry season that converted to boro rice cultivation gradually over time. The type of fishing gears and their use also changed radically over time in all the three beels.

    Journal of Nepal Geological Society, 2015, Vol. 49, pp. 65-76 River morphology and evolution of the Barind Tract, Bangladesh River morphology and evolution of the Barind Tract, Bangladesh *Md. Bazlar Rashid1, Md. Sultan-Ul- Islam2, Md. Badrul Islam2 1Geological Survey of Bangladesh, 153 Pioneer Road, Segunbagicha, Dhaka 1000, Bangladesh 2Department of Geology and Mining, University of Rajshahi, Rajshahi 6205, Bangladesh *Email: [email protected] ABSTRACT The Barind Tract is an elevated Pleistocene Terraces (about 11-48 m amsl) in northwestern Bangladesh and is widely accepted Tract to have been evolved from tectonic upliftment and /or exists as an erosional geomorphic feature. Some part of the Barind Tract bears the characteristics of morphological origin but some areas are providing evidences of tectonic upliftment. The present study is an attempt to interpret the morphological characteristics of the rivers in the area and tried to unveiling the processes that are responsible for the evolution of the Tract. River morphology are interpreted from satellite images and fi eld mapping and are used to relate neotectonic activities occurred in the area. The river forms U-shaped valleys in fl oodplain areas whereas these are V-shaped within the Barind Tract. The rivers and valleys on the Tract are also comparatively more straight, incised and entrenched, and rivers are tightly meandered, more localized, form paired and unpaired terraces, and antecedent in nature, whereas, the rivers in the fl oodplain are either meandering, braided or anastomosing drainage channels. Along the boundary between Barind and fl oodplain the rivers form asymmetric valley with steeping bank along the tract sides.
