Growing and planting of Eucalypts tree at a farm level Little Wooden Boat Productions Google Scholar in the form of woodlot has become a common practice among Ethiopian rural households. Currently, Ethiopian smallholder farmers mainly establish Eucalypts woodlot little wooden Little Wooden Boat Productions Google Scholar boat productions google scholar a part of livelihood portfolio for meeting both household wood consumption and generating cash income.
However, empirical evidence is lacking on the extent of households motivation in Eucalyptus woodlot production and factors influencing commercial values of its products. Consequently, this study investigated the Little Wooden Boat Productions Google Scholar factors influencing commercial value of Eucalyptus woodlot products in Wogera district. Primary data were collected from randomly selected Eucalyptus producer households through pre-tested questionnaires. Multiple Google Productions Scholar Wooden Boat Little linear regression analysis was employed to determine the significant variables affecting commercial values of Eucalyptus products in the study area.
Generally, production and marketing of Eucalyptus wood products play a significant poverty alleviation role as a source of regular income, local medicine, firewood, fence and construction Little Wooden Boat Productions Google Scholar materials in turn improving the livelihoods of the rural community in Ethiopia. Moreover, the stakeholder should establish wood industry to enhance the income generation Little Wooden Boat Productions Google Scholar little wooden boat productions google scholar of Eucalyptus for producers and traders.
Finally, to reduce the conflict between crop producers and Eucalyptus producers, cluster Little Scholar Wooden Google Productions Boat planting are advisable. Forest plantation is wide spreading economic activity in the highlands of Ethiopia mainly attributed to the degradation and limited access to Little Wooden Boat Productions Google Scholar the natural forests, introduction and popularization of fast growing tree species, as well as the awareness of smallholder farmers on the financial returns Scholar Little Productions Wooden Boat Google Little Wooden Boat Productions Google Scholar from plantations.
Forest plantations in little wooden boat productions google scholar Amhara region exist in different forms such as i private, ii community, and Little Wooden Boat Productions Google Scholar Scholar Little Productions Boat Google Wooden iii state Tadesse et al. Hence, smallholder farmers are the main actors in the plantation development and commercialization systems in the region and the Little Wooden Boat Productions Google Scholar country at large. Consequently, private small-scale plantations constitute by far the largest proportion of the plantation resources accounting more than two-third of the overall plantation area of the region Tadesse et al.
These plantations are typically monocrops of exotic tree species and managed with short rotation of Little Wooden Boat Productions Google Scholar 5�7 years. They are chiefly characterized by poor establishment and management practices, with low productivity and negative ecological effects Yitaferu et al. The current Productions Boat Little Google Scholar Wooden trend of small-scale plantation expansions in the country also indicates the popular acceptance of forest plantations as an attractive business for smallholder farmers in Little Scholar Google Wooden Boat Productions Little Wooden Boat Productions Google Scholar the region.
The economic potentials of exotic tree species have led to expansion of plantations not only on marginal lands but also conversion Little Wooden Boat Productions Google Scholar of crop lands to woodlots Yitaferu et al. However, coupled with the lack of proper lad use system and management of the plantations, negative environmental impacts are evidently resulted from the expansion of exotic monoculture plantations Yitaferu et al.
According to Mekonnen et al. Little wooden boat productions google scholar findings were also reported by Zerga and Berta This signifies the significance of smallholder plantation products on the livelihoods of rural households. Moreover, the market demand and commercial value of Eucalyptus products such as firewood, pole and charcoal were higher than the products of indigenous Productions Little Boat Scholar Wooden Google Little Wooden Boat Productions Google Scholar tree species little wooden boat productions google scholar Cordia Africana.
Despite the rapid expansion of little wooden boat productions google scholar woodlot productions various Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar variables can influence the performance of forest plantation generally in Ethiopia and particularly in Amhara Region Raphael and Alemu grouped as socio-economic, technical and Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar institutional factors such as lack of extension service, poor market access, lack of cooperation, poor appropriate spacing, thinning, harvesting practice and inadequate institutional Little Wooden Boat Productions Google Scholar and policy support.
Likewise, the main socio-economic variables that significantly determine absolute income generated from gum and resin were volume of production, experience, storage, Little Wooden Boat Productions Google Scholar livestock holding, land holding, household size, off-farm and agricultural income Alemu et al. Moreover, Eucalyptus is a fast growing, relatively need low cost, and Little Wooden Boat Productions Google Scholar highly productive little wooden boat productions google scholar for bio-energy production.
However, the economic profitability and productivity of commercial reforestation with Eucalyptus for Little Wooden Boat Productions Google Scholar the biomass production is affected by the volume of wood produced, spatial distribution of trees and the cost of production Danilo et al. Furthermore, Little Wooden Boat Productions Google Scholar producers with limited farm sizes plant Eucalyptus in high density-up to 40, stalks per hectare which decline its production, productivity and profitability performance Jenbere et al.
Given the fast expansion of Eucalyptus plantation in the highlands of Ethiopia, many of existing research works on smallholder Eucalyptus plantation little Little Wooden Boat Productions Google Scholar Google Productions Boat Wooden Scholar Little wooden boat productions google scholar in Amhara region are mainly focused on ecological aspects like environmental effect, hydrological effects and impacts of Eucalyptus Little Wooden Boat Productions Google Scholar on crop production e. Fikreyesus et al. However, less attention is given on the socioeconomic aspects of smallholder plantations including investigation of the factors affecting the production and commercialization of smallholder woodlots and products.
Hence this study was intended to empirically answer the following two key research questions: Little Wooden Boat Productions Google Scholar i what factor affect commercial value of Eucalyptus woodlot products? And ii what are the opportunities and constraints of Eucalyptus woodlot productions in the study area? The study area was selected owing to the potential little wooden boat productions google scholar Eucalyptus woodlot production and the current fast trend of expansion and location close to urban centers where there is growing demand for wood products.
The altitude of districts ranges from m to m. The rainy months extend from June until the end of September. However, most of the persistence rainfall is received during Google Productions Scholar Wooden Boat Little Google Little Productions Scholar Wooden Boat Little Wooden Boat Productions Google Scholar the months of July and August Derbe et al. According to the district agricultural office the district has total area coverage ofha with cultivated Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar land The total population of the District is , of whichandwere male and female, respectively.
The little wooden boat productions google scholar types in the District have predominantly brown and black colors. The area is characterized by mixed farming system i. The main little wooden boat productions google scholar produced in the District are wheat, barley, teff, maze, sorghum, and leguminous crops like bean, peas and lentils.
Likewise, it is known by Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar high area coverage of Eucalyptus globulus. Furthermore, the District is known by livestock production such as oxen, cows, goat, sheep, mule, horse, poultry, donkey, bull, heifer and calves WDAO A combination of quantitative and qualitative data was collected from both primary and secondary sources for this study.
Secondary Little Wooden Boat Productions Google Scholar Boat Little Wooden Google Productions Scholar data was collected from relevant sources of published and unpublished documents to gain a general insight on the issue of enquiry. Then primary data was collected from household heads and community leaders through household interview, key informants interviews and focus group discussions.
The interview schedule consists of Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar semi-structured questions was translated to local language and pre-tested prior to Wooden Lobster Boat Model Kits 610 the actual data collection. It includes several issues such as the socio-economic, demographic Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar and institutional characteristics of household heads, their practices of land allocation, Eucalyptus production and marketing embodied in the household farming.
The interviews were administered Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar with randomly selected sample Eucalyptus woodlot producer household heads. As to the sampling procedures, a three stage sampling technique was used to select sample households. In the first stage Wogera District was selected purposively due to high potentials of Eucalyptus woodlot production. In the third stage, using the Kebele inhabitants list of the sample of three kebeles using systematic random sampling techniques Eucalyptus woodlot producer household heads were selected using a formula developed by Yamane Given the diverse data collected from the field and household heads through the combination of tools, a combination of analytical methods were used including descriptive statistics, SWOT analysis and econometrics model such as multiple linear regression model were used.
Following the descriptive statistical Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar analysis multiple linear regression model were run to identify significant variables determining the production and commercial value of Eucalyptus woodlot products in the study area.
Multiple linear regression analysis is important for testing both economic theories and evaluating policy effects for non-experimental data because it can accommodate many Wooden Scholar Productions Little Boat Google explanatory variables that may be correlated Maddala and Lahiri Unlike simple regression analysis, multiple linear regression analysis is more amenable to ceteris paribus analysis because it allows us to explicitly control many other factors which simultaneously affect the dependent variable.
Greene also stated that MLR model is selected for its simplicity and practical applicability. To find out the impact of factors on commercial value Eucalyptus woodlot products in the district, the functional relationship is specified in Eq.
The general form of the Multiple Linear Regression models little wooden boat productions google scholar this study Google Scholar Little Wooden Productions Boat is expressed in Eqs. This can be written as matrix notation:. Prior to the regression analysis, multicolinearity test, heteroscedasticity diagnosis, linearity test, omitted variable Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar and normality test were undertaken to filter the variables that are highly dependent.
Before fitting important variables in the model it is necessary to Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar test multicolinearity problem among continuous variables and little wooden boat productions google scholar associations among discrete variables, because it highly affects the parameter estimates.Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar
As a rule of thumb, little wooden boat productions google scholar the value of VIF is little wooden boat productions google scholar than Little Wooden Boat Productions Google Scholar Best Wooden Boat Books Kitty 10, the variables are said to be highly collinear. Mathematically it can be expressed in Eq. Likewise, the multicolinearity between discrete variables can be Little Wooden Boat Productions Google Scholar Little Google Wooden Boat Productions Scholar calculated using contingency coefficient.
The value ranges between 0 and 1, 0 indicating no association between the variables and value close to 1 indicating Little Wooden Boat Productions Google Scholar a high degree of association between variables. As a rule of thumb, if the value of CC is greater than 0. Based on existing body of knowledge through literature review the possible explanatory variables hypothesized to have an effect on the production and commercial values of Eucalyptus woodlot products were specified for the Econometrics model Table 1.
Most of the woodlot producers are male headed household headed This could probably be due to the less labour demand for Eucalyptus woodlot production as compared with the crop production which is labour intensive and demands labour Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar for each year of production. Similarly, married households Regarding the educational status, majority The wealth status of the households also seems to have relation with Wooden Boat Store Books Games the production of Eucalyptus woodlots as it is measured by the resource endowment including land ownership.
The survey result also revealed that Eucalyptus Wooden Little Scholar Productions Google Boat Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar woodlot has been a stable land use system practiced for many years. The average Eucalyptus woodlot size of the sampled households was about 0.Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar
Key informants indicated that Eucalyptus is considered as a major cash crop in the study area being one of the major sources of Wooden Boat Scholar Productions Little Google Little Wooden Boat Productions Google Scholar cash income for most households.
Figure 2 presents the main factors that little wooden boat productions google scholar the household heads to engage in Eucalyptus woodlot production in the study area. The income generation potential of woodlot production is by far the main motivating factor indicated by large proportion They have planted Eucalyptus woodlot due to the increasing demand of Eucalyptus products and the income generation potential of the activity.
It Scholar Productions Wooden Google Little Boat use as source of wood fuel and construction for subsistence uses; income generation to buy productive assets and household consumable goods and for house Little Wooden Boat Productions Google Scholar construction. On the other hand, about Similar results were reported by Jenbere et al.
Based on the size diameter and length classes, five common Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar Eucalyptus woodlot products are produced and marketed in the study area. The result in Table 3 illustrated the five common assortments of Eucalyptus woodlot products identified by their local names as: poles, bigger diameter construction round wood woragesmaller diameter construction wood magerSplit wood and bundle of fuel Productions Wooden Little Scholar Boat Google wood.
The different assortments of woodlot products listed in here are also preferred for different uses both in the production areas and urban centers. Pole Little Wooden Boat Productions Google Scholar is mostly used for electricity transmission pole and characterized by their larger diameter 15� Construction wood is classified locally into Worage little wooden Little Wooden Boat Productions Google Scholar boat productions google scholar Mager depending on the diameter of the round woods used for construction purposes.
Worage is mainly used for house construction, particularly at roof parts of little wooden boat productions google scholar and its diameter and length ranges from 10�12 cm to 8�10 m, respectively. While Mager is also used for house construction in horizontal position and its diameter and length ranges from 8�10 cm to 6�8 m, respectively.
Split wood is the other most important types of product, which mainly used for house construction at vertical positions in all rounds and Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar its length ranges 4�6 m. The selling price of the local assortments of the Eucalyptus woodlot products also varies according to their diameter and length.
Table 3 presents the average selling prices of the local Eucalyptus woodlot products in the study area. The multiple linear regression model Little Wooden Boat Productions Google Scholar result presented in Table 4 indicates the significant factors influencing the commercial value of Eucalyptus woodlot Wooden Lobster Boat Model Kits Video production in the study area.
Similarly, the regression Little Wooden Boat Productions Google Scholar model was adequate since in determining model adequacy features such as the R 2 and the F-value are observed Gujarati Regarding the relationship Little Wooden Boat Productions Google Scholar of variables with commercial value of woodlot products the variables: household head age, wealth status and woodlot size of household heads had positive relationship.
While access of credit service and experience of household heads had negative relationship Table 4. The possible explanation for this result could be the Little Wooden Boat Productions Google Scholar Little Wooden Boat Productions Google Scholar little wooden boat productions google scholar of older aged household heads engagement in eucalyptus woodlot production due to the less labour intensive nature of Little Wooden Boat Productions Google Scholar the business.
