Operations Review of the German State Forest Office Wald-Michelbach

Forest owners in Germany, independent from category of ownership, have gone through a deep economic crisis for some years already, which results from increasing costs by at the same time declining incomes. However, despite difficult economic frame conditions, there are a few forest offices in Germany that have achieved very satisfactory operating results. To illuminate how this could be achieved, the state forest offices Wald-Michelbach and Beerfelden have been selected for an operations review. This study shows that the favourable financial outcome of the state forest office Wald-Michelbach results from various measures applied, all of which contribute to a high rate of operation optimization.Article信州大学農学部演習林報告 38: 133-140(2002)departmental bulletin pape

Towards exploration of plant-based ethno-medicinal knowledge of rural community: basis for biodiversity conservation in Bangladesh

Because lack of data impedes the assessment of the conservation of medicinal plants, ethno-medicinal studies are important to fill this gap. This study considered the traditional use of plants for health care by the rural communities in two forested and non-forested regions of Bangladesh. A total of 230 respondents were interviewed accompanied by field observation and voucher specimen collection. Altogether, 68 species of medicinal plants belonging to 38 families distributing over 58 genera were recorded, of which 22 species were common in both regions. Trees were the most commonly utilized growth form and leaves were the most commonly used plant part. Forests and homesteads were the major sources of medicinal plants in forested and non-forested regions, respectively. High use versatility (Relative Importance > 1) was represented by 14 species; Emblica officinale L. and Allium sativum L. were the most versatile species. Forty-one individual ailments were treated with the medicinal plants recorded. The ailment categories 'respiratory problems' and 'sexual problems' received the highest score from the calculation of informants' consensus factor (F (ic)) in forested and non-forested regions, respectively. The findings could contribute in the pharmaceutical sector by directing further investigation of bio-active compounds in medicinal plants. Secondly, results could inform the clues for conservation strategies of forest resources in that region.NEW FORESTS. 40(2):243-260 (2010)journal articl

Therapeutic use of plants by local communities in and around Rema-Kalenga Wildlife Sanctuary: implications for protected area management in Bangladesh

Traditional systems of medicine have become a topic of global importance recently. Increased commercialization of economically important medicinal plants has resulted in overharvesting, threatening their survival. The present study was carried out to document the indigenous uses of medicinal plants by the local communities in and around Rema-Kalenga Wildlife Sanctuary, Bangladesh. Data collection was predominantly qualitative recording the species use, identifying their relative importance (RI) and assessing the informants' consensus factor (F-ic) on associated knowledge. We interviewed 140 households of the local community and 5 local herbal practitioners. A total of 44 plant species were in use to treat 33 ailments under 10 broad disease categories. Five species were found to have high use versatility (RI > 1), Emblica officinale L. being the most versatile. Respiratory problems scored the highest F-ic value (0.56) involving the use of 30% of the species recorded. Terminalia bellerica Roxb., Sterculia villosa Roxb., Dillenia pentagyna Roxb. and Terminalia arjuna Bedd. were being harvested commercially. Use by the community, particularly for subsistence consumption, seemed to be sustainable, but commercial extraction of some species appeared unsustainable. Buffer zone-based commercial farming of medicinal plants with a commercial value could serve a dual purpose of assuring sustainable alternative income generation for local communities as well as conserving the natural resources in protected areas.ArticleAGROFORESTRY SYSTEMS. 80(2):241-257 (2010)journal articl

Economic Development in Post-War Cambodia Outline

A centrally planned economic was adopted in Cambodia from 1980s until 1991 when all political factions came to a peace agreement in France. Although attempts at reform start modestly in 1985, momentum was made after 1992, Initial reform was supported by the fund called Systemic Transportation Facility and the later under the Enhanced Structural Adjustment Facility. Progress has been made in moving toward a free market-oriented economy, with state owned enterprises now accounting for less than 10% of GDP. To accelerate economic development in Cambodia, the government adopted their first social economic development plan (1996-2000) with a view to consolidating the development progress. This report tries to outline the major economic development and reforms in Cambodia, based primarily on reports of the International Monetary Found (IMF).Article信州大学農学部演習林報告 38: 127-132(2002)departmental bulletin pape

Global observation of EKC hypothesis for CO2, SOx and NOx emission: A policy understanding for climate change mitigation in Bangladesh

Environmental Kuznets Curve (EKC) hypothesis is critical to understanding the developmental path of a nation in relation to its environment. How the effects of economic development processes dictate environmental changes can be found through the study of EKC. To understand the EKC phenomena for climate change, this study was undertaken by reviewing the available literature. As CO2, SOx and NOx are the significant greenhouse gases (GHG) responsible for global warming, thus leading to climate change, the study focused on those GHGs for EKC consideration. With an understanding of the different EKC trajectories, an attempt was made to determine the implications for the economic development of Bangladesh in regards to the EKC. It was shown that EKC for CO2 was following a monotonous straight line in most cases. SOx were shown to follow the full trajectory of the EKC in most situations and NOx was shown the hope only for the developed countries getting the low-income turning point. The type of economic policy that Bangladesh should follow in regards to the discussed pollutants and sources is also revealed. From these discussions, contributions to policy stimulation in Bangladesh are likely to be made. (C) 2010 Elsevier Ltd. All rights reserved.ArticleENERGY POLICY. 38(8):4643-4651 (2010)journal articl

Embracing collaborative protected area management for conservation: an analysis of the development of the forest policy of Bangladesh

With the history and experiences of more than one hundred years in formulation and revisions since the British colonial period, the forest policy of Bangladesh has turned away from a traditional production premises towards protection. Establishing protected areas for biodiversity conservation dates back to the 1960s. The strategy gained impetus with the passage of national legislation in 1973 that included the provision of declaring forests as national parks, wildlife sanctuaries and game reserves for the protection of the natural forest resources. Due to the absence of a clear demarcation between core areas and buffer zones and the absence of concern for the sustention of local communities' usufruct rights, degradation continued in the protected areas. Therefore, an alternative strategy of co-management involving local stakeholders and provision of incentives in terms of Alternative Income Generation (AIG) supports has been introduced by the government under a donor assisted project. This new policy is being implemented in five pilot sites. This co-management strategy has demonstrated positive impacts and, increasingly, is gaining recognition as appropriate for other protected areas. This paper reviews the evolutionary history of and periodical changes in the forest policy of Bangladesh - highlighting the conservation aspects, the development of protected areas and the gradual adoption of their collaborative management.ArticleINTERNATIONAL FORESTRY REVIEW. 11(3):359-374 (2009)journal articl
