Abstract: The research on the production of biodiesel has increased significantly in recent years because of the need for an alternative fuel which with biodegradability, low toxicity and renewability. The present study aimed to production biodiesel from Citrullus colocynthis seeds oil and determines its physical and chemical proprieties. The dry seeds of Citrullus Colonythis plant were obtained from Elmatama locality. Citrullus Colonythis seeds were minced and its oil was extracted by using a soxhlet (hexane as solvent. The oil content percent of the seeds was 18.91% and then was subjected to transesterification reaction until the biodiesel (C. Colonythis oil ethyl ester - CCOEE) was produced. Biodiesel properties were investigate which were; kinematic viscosity 9cSt, the calorific value 43.82 MJ/ Kg, the density 0.906 g/m3, the specific gravity 0.913, the pour point -33°C, micro carbon residue 0%, Acid value 0.6 mg KOH/g and API number 23.29. The density of CCOEE was found to be closed to the limits specified ASTM standard for biodiesel and diesel fuel which were 0.88 g/m3 and 0.823 g/m3 respectively. The kinematic viscosity of CCOEE measured at 50°C was higher when it compared with ASTM standard, (1.6 - 6.0) for biodiesel and (1.9 - 4.1) for diesel fuel. While calorific was well within the range of diesel standard 45.5 MJ/kg and the calorific value of biodiesel is 37.27 MJ/kg. Micro Carbone residue was determinate according to ASTM standard method the CCOEE biodiesel (0%)) was found in the range of ASTM, the (0.05%) is maximum limit. The biodiesel produced from CCOEE had a flash point of 55°C, this result it close to flash point of diesel fuel (52°C) and so far of flash point of biodiesel it was 130°C that made biodiesel is safe for transportation purpose.

Abstract: Due to land scarcity, agricultural land infertility, high population pressure and recurrent drought, the government of Ethiopia implemented resettlement programs in 2003 EC before 15 years. The program aimed at addressing the problem of drought and famine through improved access to land and availing institutional support. In light of this, the objective of the study is to identify existing livelihood strategies adopted by rural households and analyze factors that determine households’ participation to choose alternative livelihood strategies in Buno Bedele Zone, Chewaka resettlement district. The data were collected through both primary and secondary data collection methods. The data were obtained from 137 sample household heads that were selected through simple random sampling techniques. The study used both descriptive and econometrics for analysis. The descriptive statistics were used to explain socio economic characters of the household comparison which it resettlers have better encouragement than the hosts community,… and it was used to identify the existence of livelihood strategies that was 60.72 percent of households total annual income from the on farm strategy (agriculture) and 23.46/15.81percent was from off/nonfarm activities. Multinomial logit model applied to analyses the factors that determine households’ participation to choose alternative livelihood strategies. In this regard, the econometric investigation indicate that out of the total seventeen variables included in the models four variables in non and off farm activities, ten variables in off farm and on farm strategies, eight variables in combination of on farm, off farm and nonfarm activities and four variables in on farm and nonfarm activities were solely or simultaneously in different strategies significant including age of household heads, family size, dependent ratio, settlement fragmentation, number of oxen, irrigation access, education access, land size, livestock holding size, sex of household head,, market distance, total annual income from on farm, membership in local association, extension service, agricultural input use and credit access are found to be the significant determinants up to 10% probability levels. The results of this study recommend that resettlement implementation should be for sustainable livelihood development. To do so, higher concern would be given to the environmental issue and both agricultural intensification and non/off farm strategies could be strengthened to raise positively farmers’ participation in various livelihood strategy.
