    Md. Sirajul Islam, Md. Hasan Imran, Md. Humayun Kabir, Md. Masud-Un-Noby, Md. Enamul Hoq, Sunzida Haque Rimu, Md. Safiur Rahman

    Abstract:  This study was conducted to know the seasonal dynamics of heavy metal (Zn, Cu, Cr, Cd, Pb and Hg) concentrations in marine fish from the Bay of Bengal coast of Bangladesh in pre-monsoon, monsoon and post-monsoon seasons. The fish samples of various species viz. Churi (Trichiurus lepturus), Loittya (Harpadon nehereus), Ilish (Tenualosa ilisha) in St-1; Churi, Loittya, Ilish, Surma (Euthynnus affinis) in St-2; and Poa (Otolithoides pama), Loittya, Ilishin St-3 were collected seasonally from fish landing stations during December 2017 to November 2018. The samples were analyzed by using UNICAM-929 atomic absorption spectrophotometer following AOAC (2012) in the Food Laboratory of the SGS Bangladesh Limited., Dhaka. The results showed that among the metals, only Zn was detected in every station over the seasons. Overall metal accumulation, Zn content found more followed by Cu and Cr, whereas Cd, Pb and Hg were below the lower limit of detection in all the collected fish samples. Therefore, the study concluded that the fish are safe for human consumption as well as for public health and food safety measures ensured by common marine fish of Bangladesh.

    Community Based Forest Management in Nepal: Current Status, Successes and Challenges

    Pramod Ghimire, Uchita Lamichhane

    Abstract: Community based forest management in Nepal has been widely acclaimed as the most successful approach for participatory forest management and its governance. So far, about 2,831,707 hectares of forests of Nepal have been managed under the regime of community-based forest management. During four decades of its implementation, the program has undergone a considerable shift from state dominated top-down approach to community-based participatory approach to forest management through organizational and policy reform in Nepal. The success of community-based forest management approach is described in terms of improving the supply of forest products, generating green employment, improving rural livelihood, empowering women, poor and disadvantage groups, rehabilitating degraded land and habitat and also increasing biodiversity. Yet, community-based forest management approach continues to face some organizational and policy challenges during its implementation, and this cannot be overlooked. Social exclusion, inequitable benefit sharing, elite dominance in decision making are the major challenges that are to be resolved in the years to come. Furthermore, this paper intends to illustrate the lessons learnt and the current challenges in making the decentralized forest governance more successful in the changing context.

    Abstract: The study for this paper was conducted to assess the proximate compositions, heavy metal concentrations and pesticide residues in marine dried fish. The selected fish were silver pomfret (Pampus chinensis), bombay duck (Harpadon nehereus), ribbon fish (Trichiurus savala), sardine (Salmostona bacaila) and anchovy(Colia dussumieri) collected from the Cox’s Bazar, Kuakata (Patuakhali) and Dubla Island (Khulna) of Bangladesh coast. The moisture content ranged from 11.27% (S. bacaila) to 38.94% (P. chinensis) among the dried fish products. Protein content varied from 51.33% (C. dussumieri) to 77.68% (T. savala). The As concentration varied from 8.41 mg/kg to 22.27 mg/kg only in T. savala. The Fe content was measured 116.85 mg/kg to 160.18 mg/kg in H. nehereus and P. chinensis. The Zn concentration varied from 31.08 mg/kg to 36.74 mg/kg. Among heavy metals, As, Fe and Zn concentration were found higher than the permissible level for human consumption. However, Cd, Cu and Pb tested were found within the permissible level in all three species. The residue of organochlorine pesticide was found within the maximum residue limit level recommended by World Health Organization. The existence of pesticides residues in the samples of this study is a matter of health concern as this poisoning has long term effect on human health.

    Non-Timber Forest Products and their Role in the Livelihoods of People of Nepal: A Critical Review

    Sami Shrestha, Jiban Shrestha, Kabita Kumari Shah

    Abstract: Nepal is a rich source of Non-Timber Forest Products (NTFPs) in terms of production and trading practices. The altitudinal and climatic variations in various pockets of Nepal have contributed to their diversity. This article attempts to outline the current status of NTFPs and its importance in the Nepalese economy. NTFPs provide rural people with food, medicine, construction materials, and income. About 80% of the rural population depend on the NTFPs for their livelihood and Nepal. NTFPs have commercial, socioeconomic and environmental values ​​in rural communities. More than 700 species of plants are recognized as producing NTFPs and about 150 species of these are commonly used in international trade. The management of NTFPs has been receiving increasing attention from donors, development agencies and user groups who are involved in different aspects of NTFP promotion. Sustainable exploitation, use, and commercialization of NTFPs are important for socio-economic development, poverty reduction, and livelihood enhancement of rural people in Nepal.

    The Role of the Constitution in Effective Disaster Management of Bangladesh

    Fayjus Salehin, Md. Nuralam Hossain, Abdur Rakib Nayeem, Md. Rakibul Hassan

    Abstract: Bangladesh is prone to recurring natural hazards due to its geographical position and topography. The country has suffered casualties and damage to homes, agriculture, and the economy as a result of tropical cyclones. Effective disaster management approaches are required to reduce the risk of disaster and loss. The Constitution of Bangladesh plays an active role in implementing these approaches at the national and sub-national level. This article analyzes parts of the Constitution addressing disaster management by ensuring disaster governance and adaptive governance. To examine the theoretical aspects of disaster management from a global and Bangladesh perspective, the current institutional role for disaster management, the difference in service delivery for specific organizations, and human rights and humanitarian aspects, a study was conducted based on secondary data and information. Bangladesh's supreme law supports all phases of the disaster management cycle. Consequently, it is said that the Constitution would be an essential document for effective disaster management at all levels.
