 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Dimensions of Food Insecurity and Adoption of Soil Conservation Technology in Rural Areas of Gursum District, Eastern Ethiopia) ผู้เขียน:Abebaw Shimeles, เพ็ญพร เจนการกิจ, ดร.วุฒิ หวังวัชรกุล, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractDefining food security in terms of availability and access to sufficient food to meet dietary needs for a productive and healthy life, this paper assessed the dimensions of food insecurity and its association with the adoption of soil conservation technologies in the Gursum district of Eastern Ethiopia. Stratified random sampling was employed to select 280 rural households, from which primary data were acquired by means of structured questionnaires. This study applied the Foster, Greer and Thorbecke (FGT) model, which was originally developed for poverty analysis, to examine the incidence of food insecurity, and the food insecurity gap and severity of food insecurity. Sixty seven percent of the total sampled households adopted structural soil conservation measures. Of those who were adopters, 43 percent and 57 percent undertook traditional and introduced soil conservation measures, respectively. The results indicated that almost 66 percent of the sampled households were food insecure during the survey period, with the food insecurity gap and severity of food insecurity being 27 and 14 percent, respectively. Moreover, food insecurity was also found to be significantly higher in households that were non-adopters of soil conservation measures. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Analysis of Factors Affecting Adoption of Soil Conservation Measures among Rural Households of Gursum District, Ethiopia) ผู้เขียน:Abebaw Shimeles, เพ็ญพร เจนการกิจ, ดร.วุฒิ หวังวัชรกุล, รองศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractLand degradation in the highlands of Ethiopia is reaching an irreversible state. It has become increasingly difficult to maintain the current level of production of basic food items. Government and nongovernmental organizations have attempted to promote soil conservation technologies. However, their attempts have not succeeded in activating voluntary adoption to the expected level. This paper examines the main determinants of farmers? adoption decisions and the use intensity of level bund soil conservation measures using a cross-sectional sample of 280 farm households in the Gursum district of Eastern Ethiopia. Tobit analysis was employed to analyze the data. The results showed that highland agro-ecological location, slope, educational level of the household head, extension service, land tenure security, access to credit, and offfarm income are important factors that positively influence the adoption and intensity of use of level bunds in the study area, whereas livestock holding had a negative influence. This study suggested that to assure voluntary soil conservation adoption, the government needs to entrust land tenure security to farmers, promote formal and informal training on land management and utilization, and establish a targeted credit scheme that would integrate crop production and soil conservation in the study area. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Quantitative Methods for Analysis of Factors Influencing Farmers’ Adoption of Technology.) ผู้เขียน:Aree Wiboonpongse สื่อสิ่งพิมพ์:pdf Abstract A study on factors influencing the adoption of farm innovation aims at understanding of farmers’ socio-economic characteristics, which affect farmers adoption. This paper reviews quantitative methods employed in the recent studies of adoption determinants and compares empirical results of the 6 methods applied to adoption of grass strip in integrated soil water conservation cropping systems in Mae Hong Son highlands, include ; (i) Spearman rank correlation (ii) chi-square test (iii) A model with grass strip area as dependent variable using the least square (LS) technique (iv) A logit model of grass strip ratio to total land holding of adopters with LS technique (v) A binary dependent model using LS technique and (vi) Finally Logit model for the binary dependent variable with maximum likelihood estimation. Since the tests of the independence of nonparametric methods rest on the impact of a given factor and ignore the influence of the others, their results are not all consistent with obtained by parametric methods. The techniques applied to models (iii), (iv) and (vi) are considered appropriate as the tests indicated that the specified models explain correctly. Nevertheless, the choice of the model depends on the information available for the dependent variable and its implication. The method (v) is not acceptable theoretically as the predicted value possibly goes beyond 0 and 1 and moreover, accuracy of prediction is only 77% as compare to 90% obtained from likelihood estimation. |
หัวเรื่อง:มาตรการอนุรักษ์ดินและน้ำ : กรณีศึกษาการดำเนินงานในภาคตะวันออก ผู้เขียน:ดร.ผ่องพรรณ ตรัยมงคลกูล, รองศาสตราจารย์ , ดร.ประสงค์ ตันพิชัย, รองศาสตราจารย์ , Arunsiri Kumlang สื่อสิ่งพิมพ์:pdf AbstractThis is a case study of the Land and Water Conservation Center project implemented in the selected
7 eastern provinces by Department of Land Development (DLD), under the cooperation of the Japanese
government. Objectives of this study were to assess suitability of the conservation measures, effectiveness,
problems and constraints of the pilot project implementation, and to propose recommendations for further
adaptations of the model for soil and water conservation measures.
The contextual analysis revealed that the project goal was not clearly perceived at the practice level.
There were unadequate inputs in terms of follow-up budget and personnel to maintain the mechanical structure
and equipment. The pilot site was appropriately selected for technology testing in terms of physical condition,
but with some problems in the social background of participating farmers. Overall administrative structure
and plan of the project were well developed. However, the problems existed in the project coordination and
monitoring, incongruence of the target plan and the actual implementation. Technology testing was not fully
implemented, particularly on-farm experiment. Follow-up and evaluation of the project was unadequate. The
output analysis revealed that the mechanical and vegetative measures were suitable for the project area.
However, extension activities were much needed to support the adoption of vegetative measures by farmers.
Farmers did not fully perceive the benefits of the conservation measures, hence a lack of participation in the
maintenance. The DLD official benefited much from the knowledge transfer, but knowledge implementation
was limited. Data were lacking to indicate the physical outcome of the conservation measures. Overall, the
project goal was attained in output rather than outcome.
For further adaptation of the conservation technology and model, it was recommended that the integrated
nature of the project should be maintained by incorporating into the routine activities of the provincial DLD
offices. To ensure a successful and sustainable implementation, selection of project sites should be based on
the activeness of the local farmers, group dynamics, and local leaders and organizations. |

 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Nitrogen Fertilization and Moisture Conservation Practices on Maize (Zea mays L.) Grown Under Dryland Conditions of Ethiopia) ผู้เขียน:Girma WOLDETSADIK, ดร.สมบัติ ชิณะวงศ์, รองศาสตราจารย์ , รังสิต สุวรรณเขตนิคม, นางสุนันทา จันทกูล, ผู้ช่วยศาสตราจารย์, ดร.อภิพรรณ พุกภักดี, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractA Field experiment was conducted during the rainy season of 2003 to study the effect of nitrogen levels and moisture conservation practices on soil, water, yield and yield components of maize (Zea mays L.) in the rift valley of central Ethiopia. Grain yield was influenced by nitrogen fertilizer levels but 1000 grains weight, total biomass, straw yield, soil temperature, soil moisture content, and infiltration rate were not affected by nitrogen levels. Signifcant effects of harvest index and water use efficiency by nitrogen levels were observed only at Dera and Melkassa respectively. Moisture conservation practices gave more improvement in grain and straw yields, harvest index, and total biomass over flat bed due to availability of moisture than separate application. Bulk density, infiltration rate, water use efficiency, and soil moisture content were also affected by moisture conservation practices. The effect of mulch to reduce the soil temperature was observed prior to maize maturity. |
