Livelihood Pattern and Forest Dependence of the Major Tribes in Rangamati, Bangladesh

Indigenous people are of great interest and intense significance from forest perspective, as they inhabit for a very long time over the same region. In Bangladesh, tribal communities reside with close touch of forests and thus, quite dependent on it. That’s why, it of tremendous importance to study their Do’s and Don’ts in order to propose better forest and environmental management interventions considering options for enhancing livelihoods of the indigenous communities in Bangladesh. In this research, four major tribes of Rangamati in four sites have been purposively selected for questionnaire survey. Data has been taken into consideration from two vital viewpoint, livelihood pattern and forest dependence, assuming that all tribes are dependent on forest resources for their livelihood. And it is found that, Tanchangya and Chakma community are more economically well-off in terms of land ownership and income per capita respectively. Forestry practice provides little share in their total income though Tanchangya community has the highest land per capita in forestry sector as well as in agricultural sector. On the other hand, Marma community’s living standard is comparatively low as their income and land per capita is low, and they are more dependent on forest. Tripura community keeps the comparative middle status in almost every sector. A variety of other social and environmental factors were also collected and thoroughly analyzed here which can be very useful for further study.OtherShinshu University International Symposium 2010 : Sustainable Agriculture and Environment : Asian Networks II 　信州大学国際シンポジウム2010 : 持続的農業と環境 : アジアネットワークII ― アジアネットワークの発展をめざして―. 信州大学農学部, 2010, 45-58conference pape

Determinação da produção de casca de acácia-negra, Acacia mearnsii De Wild.

Thepresent research was undertaken with black wattle, Acacia mearnsll De Wiil. The objetive was to determine green bark yield, estimated through an equation obtained by a production model, related to age, dominat height and basal area, expressed by the generic model: log C = b0 + b1 h0² + b2 log G, where C = green bark weight per hectare: G= basal area per hectare:  h0 = dominat height. This equation showed a high precision. The independent variables, dominat height and basal area explicated 97,8% of the green bark yieldvariation per hectare.O presente trabalho foi desenvolvido com acácia-negra, Acacia mearnsii De Wild., e teve como objetivo a elaboração de tabelas de produção de casca verde, estimadas através de equações obtidas por modelagem da produção em função da idade, altura dominante e área basal, expressa pelo modelo genérico: log C = b0 + b1 h02 + b2 log G, sendo C = peso de casca verde por hectare; G = área basal por hectare; ho = altura dominante. Esta equação apresentou uma alta precisão, sendo que as variáveis independentes, altura dominante e área basal, explicaram 97,8% da variação da produção de casca verde por hectare

Über ökonomische Theorien der forstlichen Nachhaltigkeit: Eine ideengeschichtliche Auseinandersetzung mit Deegens Aufsatz "Die Stellung der Tharandter Theorien der forstlichen Nachhaltigkeit in Hayeks Klassifikation der Formen menschlicher Ordnung" (veröffentlicht in ORDO (2013: 79-97))

Peter Deegen hat 2013 eine originelle, Neues bietende und gängigen Auffassungen der Forstökonomik widersprechende Arbeit zu Theorien der forstlichen Nachhaltigkeit vorgelegt. Die Arbeit ist der theoretischen Forstökonomik zuzuordnen. Es geht dem Autor darum, verschiedene ökonomische Konzepte forstlicher Nachhaltigkeit mittels der Hayek'schen Theorie der Formen menschlicher Ordnung zu systematisieren und so theoretischer Erklärung zugänglich zu machen. Im vorliegenden Arbeitspapier wird kritisch hinterfragt, ob das Neue und Originelle in der Arbeit auch in der Sache haltbar ist. Hinterfragt werden Deegens Definition von Nachhaltigkeit, seine forstgeschichtlichen Deutungen zu den Arbeiten von Cotta, Preßler und Judeich, sein methodisches Vorgehen (eine Kombination von typologischer Methode und biographischer Methode der Geschichtswissenschaften) sowie seine auf die marktwirtschaftliche Ordnung verkürzte Darstellung der Ordnungstheorie von Hayek. Als Alternative zur an Hayek orientierten typologischen Methode wird ein ideengeschichtliches Vorgehen vorgeschlagen und am Beispiel der Auseinandersetzungen von Boden- und Waldreinertragslehre im 19. Jahrhundert illustriert. Abschließend wird hinterfragt, warum Deegens Modell der "Forstwirtschaft der Preise" der Idee der Nachhaltigkeit nicht genügt und begründet, warum Forstwirtschaft in einer Marktwirtschaft einen sozial und ökologisch verpflichtenden Ordnungsrahmen braucht, damit Nutzung und Schutz der Wälder nachhaltig erfolgen
