Dimensions of Poverty in Northeastern Ethiopia: Looking into Multitude Facets of Poverty for Poverty Reduction
Despite efforts being made and some signs of change, poverty in Ethiopia is staggeringly high and thus the country is undoubtedly among the poorest nations in the world in which poverty persists at debilitating levels and hence becomes multifaceted and longstanding problem over periods. The situation of northeastern Ethiopia, one of the poverty stricken areas in the country, does not be different from the above situations. A thorough examination different dimension of poverty and estimating the extent of each dimension are important for policy measures to tackle poverty. This study is, therefore, aims to analyze the economic, social and institutional dimensions of poverty in the northeastern Ethiopia. The study employed rural household survey questionnaire based on income and expenditure dataset of the 400 sample households from four study weredas using a two stage random sampling method proportionate to size. Data on the demographic, socio-economic and institutional characteristics of the sample households are also collected so as to analyze the various poverty dimensions. While the cost of basic needs approach was used to determine the poverty line, FGT family of poverty indices were used to estimate the extent of poverty in monetary terms. In addition, the analysis of multidimensional poverty is also supplemented by additional measures of poverty in terms of the economic, social and institutional aspects using the summary statistics and t-tests. Concerning the monetary measures of poverty, the absolute food and total poverty line are ETB 2866.14 and 3410.71 respectively and the extreme food and total poverty lines are 2149.39.59 and 2557.77 respectively. Based on the above absolute total poverty line, the incidence of poverty in rural northeastern Ethiopia is 39 percent. With regard to the other economic and social dimensions of poverty, households identified as poor in our survey confirms that they are worse off in almost all dimensions than average or better-off households so that poverty in rural northeastern Ethiopia is truly multi-dimensional. As a result, in most cases rural households in the study areas are facing adverse socio-economic composition which in turn increases the likelihood of falling into poverty. Therefore, the identified multitude dimensions and the respective estimated magnitudes of poverty in the study areas are worth considering as a positive knock for policymakers and anyone else who may have a stake on poverty reduction and hence better livelihood of rural households in northeasten Ethiopia in particular and in the country in general.

Climate Variability, Communities\u27 Perceptions and Land Management Strategies in Lay Gayint Woreda, Northwest Ethiopia
Climate variability is the fluctuation of climatic elements from the normal or baseline values. Agrarian communities are the most sensitive social groups to climate variability and associate extreme weather-induced hazards due to the fact that climate variability affects the two most important direct agricultural production inputs, such as rainfall and temperature. As Ethiopia is heavily dependent on agriculture its economic development is being hindered by climate variability coupled with many other deriving forces. Therefore, the objective of this study is to examine climate variability, local communities\u27 perceptions and land management strategies to reduce the adverse impact of climate variability in Lay Gayint Woreda, Ethiopia. Both primary and secondary data were used to complete this study. Primary data were collected and analyzed from a total of 200 randomly selected respondents reside in different agro-ecological areas. Metrology data were gathered from Nefas Mewcha Station from the years 1979 to 2010. Standardized rainfall anomaly index (SRAI), crop diversification index (CDI) and other descriptive statistical techniques were used to analyze the data. The results obtained from the climate data revealed an increase in temperature, and decrease and/or erratic in rainfall distribution. Time series SRAI from 1979 to 2010 indicates that 2002 and 2008 were characterized by extreme and severe dry conditions in order of importance with high impact on crop yields whist only 1984 and 1990 received near normal rainfall amount. Similarly, the survey result reveals that out of the total household heads, 87.5 % perceived that there was an increase in temperature over the last 20 years. The survey result also disclosed that significant numbers of households are more likely to adopt different land management strategies to reduce the negative impact of climate variability. Constructing terraces and check dams as well as planting trees were the major land management strategies used by the local communities. However, crop diversification index (CDI) was found to be 0.11 as the cultivated area is stanch to one crop indicating very low alternative crop production in the study area. Although the study area receives variable and inefficient rainfall the rugged topography and poor soil conditions have hindered the development of irrigation facilities. Local context-specific integrated watershed management activities, small-scale irrigation schemes and extension services need to be strengthened to reduce the impact of climate variability. Policy makers need also to substantially invest in establishing information dissemination systems in order to provide reliable weather information for farmers given that crop production is largely dependent on it

The export performance of emerging economy firms: the influence of firm capabilities and institutional environments
We advance a two-stage theoretical model which contends that the export performance of emerging economy firms (EEFs) will depend both upon their firm-specific capabilities and their home institutional environments. Specifically, we argue that EEFs will be more likely to export when facing more uncertainty at home from greater political instability, substantial informal competition, and high corruption. Furthermore, we hypothesize that firms’ export intensities will be contingent upon specialized internal capabilities such as a skilled workforce, top managerial experience, and access to external technologies. We test these hypotheses using a dataset of more than 16,000 firms from the four BRIC economies (i.e., Brazil, Russia, China and India). Our results confirm that political instability and informal competition have robust effects on the export propensity of EEFs, whilst export intensity is contingent upon the availability of skilled workers and access to external technologies via licensing
Mechanical Property of Plastic Lumber Produced from Recycled High Density Polyethylene (HDPE)
Recycling is a strategy to combat environmental pollution due to plastic wastes. Of the many plastic wastes, researchers confirmed the possibility to produce plastic lumber from used HDPE plastics. The aim of this study is to experimentally determine the mechanical property of the plastic lumber produced from pure HDPE and its composite with wood to proof usability and applicability for different purpose. The experiment considered different conditions. Pure plastic lumber and wood plastic composite lumber is initially produced and examined under room temperature and below room temperature. Under each condition, bending, tensile and impact strength were examined. For each test eight specimens were prepared based on international standards and the experiments were conducted using standard testing machines. The result shows that pure plastic lumber has demonstrated superior load carrying capability, tensile load resistance capability and impact load resistance at room temperature. Moreover, the pure plastic lumber has an elastic nature and the wood composite has a brittle nature. In both cases the mechanical property of the plastic lumber permits to use for different applications. This has been also tested and resulted in similar phenomena at 20C below room temperature
Application of GIS on Environmental Degradation Due to the Offshoots of Highway Development Projects: Central Ethiopian Highlands
Physical land degradation after road building has been observed in Central Ethiopian highlands through gully erosion. In this research work by using a number of methods such as Field observation, gully measurement, GIS technique, the 1997 and 2006 topomap and socio-economic questionnaires, the impacts of the road on land degradation has been studied. It investigates how highway construction in the Ethiopian Highlands affects the gully erosion risk by quantifying the catchment area before and after road construction, the number of gullies created, and its characteristics in two selected cases: Addis Ababa-Fiche and Addis Ababa-Ambo. Accordingly; since the building of the road, 17 new gullies were created immediately down slope of the studied road segments and 8 other gullies at a radical change in its dimensions. The average catchment area is now 58.28 hectares and 74.52 on the road segments of Fiche and Ambo respectively, which is significantly different (p<0.001) from the average pre-road catchment area of 8.45 and 14.52 hectares (paired average). The total surface area occupied by gullies in the side of Fiche road and in the side of Ambo road transects was about 63,892.6 m2 and 59,214.25 m2 respectively. The volume of soil loss was calculated between 12,530.38 m3 and 71,420 m3 from each road segments. The result of statistical analysis indicates that variation of the gully length contributed 95% of variation in the volume of soil loss. The Gully density (5.7m/ha to 14.06m/ha) implies that the sampled roadside areas were moderately to severely degraded. The damages and associated problems of the gullies, as explained by farmers, include loss of land, dissection of farms, and deposition of sediments on growing crops and in extreme cases putting agricultural fields out of production. Hence roads should be designed in a way that keeps runoff interception, concentration and deviation minimal. Techniques must be used to spread concentrated runoff in space and time and to increase its infiltration instead of directing it straight onto unprotected slopes.Key words: Gully erosion Risk, catchment area, Road design, Ecological destruction
Podoconiosis and soil-transmitted helminths (STHs): double burden of neglected tropical diseases in Wolaita zone, rural southern Ethiopia
Background
Both podoconiosis and soil-transmitted helminth (STH) infections occur among barefoot people in areas of extreme poverty; however, their co-morbidity has not previously been investigated. We explored the overlap of STH infection and podoconiosis in Southern Ethiopia and quantified their separate and combined effects on prevalent anemia and hemoglobin levels in podoconiosis patients and health controls from the same area.
Methods and Principal Findings
A two-part comparative cross-sectional study was conducted in Wolaita zone, southern Ethiopia. Data were collected from adult patients presenting with clinically confirmed podoconiosis, and unmatched adult neighborhood controls living in the same administrative area. Information on demographic and selected lifestyle factors was collected using interviewer-administered questionnaires. Stool samples were collected and examined qualitatively using the modified formalin-ether sedimentation method. Hemoglobin level was determined using two different methods: hemoglobinometer and automated hematology analyzer. A total of 913 study subjects (677 podoconiosis patients and 236 controls) participated. The prevalence of any STH infection was 47.6% among patients and 33.1% among controls (p<0.001). The prevalence of both hookworm and Trichuris trichiura infections was significantly higher in podoconiosis patients than in controls (AOR 1.74, 95% CI 1.25 to2.42, AOR 6.53, 95% CI 2.34 to 18.22, respectively). Not wearing shoes and being a farmer remained significant independent predictors of infection with any STH. There was a significant interaction between STH infection and podoconiosis on reduction of hemoglobin level (interaction p value = 0.002).
Conclusions
Prevalence of any STH and hookworm infection was higher among podoconiosis patients than among controls. A significant reduction in hemoglobin level was observed among podoconiosis patients co-infected with hookworm and ‘non-hookworm STH’. Promotion of consistent shoe-wearing practices may have double advantages in controlling both podoconiosis and hookworm infection in the study area
Prevalence of Trachoma in Gambella Region, Ethiopia: Results of Three Population-Based Prevalence Surveys Conducted with the Global Trachoma Mapping Project.
PURPOSE: In Ethiopia, trachoma is a major public health problem, accounting for 11.5% of all cases of blindness. In Gambella, one of the country's most remote regions, the 2005-2006 National Survey of Blindness, Low Vision and Trachoma estimated a region-level prevalence of active trachoma of 19.1% in those aged 1-9 years. Detailed district or sub-regional level estimates are required to implement interventions. METHODS: Population-based prevalence surveys were carried out following a 2-stage cluster random sampling methodology and Global Trachoma Mapping Project protocols. As the 13 districts (woredas) in Gambella had relatively small populations, they were grouped together to form three evaluation units (EUs) of about 100,000 persons each, and all subsequent survey planning and sampling was carried out at EU-level. RESULTS: Altogether, 558 cases of TF (17.2%) were identified in 3238 children aged 1-9 years across the three EUs. The adjusted TF prevalences in 1-9-year-olds for the three EUs were 11.5%, 12.5% and 19.3%; 14.4% for Gambella overall. A total of 142 cases of trichiasis (3.8%) were identified among 3781 adults aged 15 years or older, with age- and sex-adjusted EU-level trichiasis prevalences in adults being 0.8%, 1.3% and 2.4%; 1.5% overall. CONCLUSION: The high prevalences of TF and trichiasis throughout Gambella indicate a need for rapid scaling up of the World Health Organization SAFE strategy (surgery, antibiotics, facial cleanliness, and environmental improvement) to help meet the 2020 target of global elimination of trachoma as a public health problem
