Structural Soil and Water Conservation Practices in Farta District, North Western Ethiopia: An Investigation on Factors Influencing Continued Use

Soil degradation is one of the most serious environmental problems in Ethiopia. The Ethiopian highlands have been experiencing declining soil fertility and severe soil erosion due to intensive farming on steep and fragile lands and other factors attributed to population pressure. Although different soil and water conservation structures have extensively been  introduced over the past decades, sustained use of the measures was notas expected. The limited success of those efforts highlights the need to better understand the factors that influence sustainable use of structural soil and water conservation measures. This study used logistic model to investigate the major factors influencing the continued use of structural soil and water conservation measures in Farta district. Both purposive and simple random sampling techniques were applied to select sample kebelesand representative households respectively. Data collected from 162 sample households were used to estimate the logistic model. The result shows that only 47.2 percent of the respondents continually used the structural conservation measures and the remaining were not due to different determinant factors, of which perception of farmers on erosion and technology profitability was the major factor followed by institutional factors including tenure security, extension contact, access to training and membership in local organizations. Therefore, plan for intervention in soil conservation and sustainable use of measures should recognize these heterogeneous conditions and farmers’ preferences

Availability of Adequately Iodized Salt at Household Level and Associated Factors in Dire Dawa, Eastern Ethiopia

In Ethiopia, Iodine Deficiency Disorder has been recognized as a serious public health problem for the past six decades. In 2011, an estimated 12 million school-age children were living with inadequate iodine, and 66 million people were at risk of iodine deficiency. One out of every 1000 people is a cretin mentally handicapped, due to a congenital thyroid deficiency, and about 50000 prenatal deaths are occurring annually due to iodine deficiency disorders. Only 5.7% of the households were using iodized salt in Dire Dawa city Administration, which is below the legal requirement.This study assessed availability of adequately iodized salt at household level and associated factors in Dire Dawa town, East Ethiopia. Community based cross-sectional study was carried out among households in Dire Dawa town during March 16-26, 2015. Multistage sampling technique was used. Data were collected using a pretested and structured questionnaire by a face-to-face interview technique. Bivariate and multivariate analyses were performed to check associations and control confounding. A total of 694 participants were participated. The availability of adequately iodized salt (≥15 parts per million) in the study area was 7.5% (95% CI; 5.6-9.5). Multivariate result showed that health information about iodized salt (AOR=8.96, 95% CI; 4.68-17.16) (p=0.03), good knowledge about iodized salt (AOR=9.23, 95% CI; 3.34-25.5) (p=0.01) and using packed salt (AOR=3.99, 95% CI; 1.48-10.73) (p=0.006) were associated with availability of adequately iodized salt at household level. Availability of adequately iodized salt at household level was very low. Hence, households should be sensitized about importance of iodized salt and its proper handling at the household level

Levels of essential and toxic metals in Ethiopian khat, (Catha Edulis Forsk.)

Khat chewing is a common habit in East Africa and Arabian Peninsula. However, detail of in-organic elemental content of this plant is scarcely known. Samples of khat (Catha edulis) were collected from different parts ofEthiopia. The leaf parts, which are chewed, were separated and air dried at room temperature. The dried samples were grounded to a fine size by the use of stainless steel mills. One gram was mineralized for metal analysis via digestion in aqua regia under reflux. Spiking was performed to check the accuracy of the digestion procedure. Recoveries varied from 84.5 % to 109.6 %. Thirteen metal concentrations were measured by Flame Atomic Absorption/Emission Spectrometer and Graphite Furnace Atomic Absorption Spectrometer employing an external calibration curve. Levels of metals (mg/kg) on Dried Weight Basis were recorded as follows; Cu: 5.11-9.55 Cd: 0.03-6.54 Pb: non detectable to 1.57 Zn: 4.15-89.3 Mn:6.45-20 K: 5929.65-10948 Na: 218.2-842.25 Li: 0.1-0.85 Al: 2448.15-8556.45 Ba: 12.13-1479 Mg: 1798.5.5-3098.75 Fe: 260.95-1551.8 Ca: 2190.9- 10985.8. The possible consumption for the measured elements by chewing khat on regular basis lies within the recommended daily allowance (RDA) except for Al, Fe and Ba. Detection of toxic elements like Cd and Pb in khat plant samples investigated might be related to possible introduction of artificial contaminants to the ecosystem of Ethiopia. But the quantities found are in very small amounts thus there should not be an alarm  although usual precautions of keeping the environment safe from artificial hazards is necessary. The levels of the analyzed elements in khat that surpassed the RDA i.e. Barium may expose the khat users to damages toheart, blood vessels and nervous system, Iron may facilitate growth of certain pathogenic microorganisms and Aluminium also had unconfirmed correlations under study with neuro-disorders.Key Words: Khat, Catha edulis, Metals, Flame Atomic Absorption/Emission Spectrometer (FAAS), Graphite Furnace Atomic Absorption Spectrometer (GFAAS), Ethiopia

Runoff estimation and water management for the Holetta river in Ethiopia

The hydrology of Holetta River and its seasonal variability is not fully studied. In addition to this, due to scarcity of the available surface water and increase in water demand for irrigation, the major users of the river are facing a challenge to allocate the available water. Therefore, the aim of this research was to investigate the water availability of Holetta River and to study the water management in the catchment. Soil and Water Assessment Tool (SWAT) modelled the rainfall runoff process of the catchment. Statistical (coefficient of determination [R2], Nash- Sutcliffe Efficiency Coefficient [NSE] and Index of Volumetric Fit [IVF]) and graphical methods used to evaluate the performance of SWAT model. The result showed that R2, NSE and IVF were 0.85, 0.84 and 102.8, respectively for monthly calibration and 0.73, 0.67 and 108.9, respectively, for monthly validation. These indicated that SWAT model performed well for simulation of the hydrology of the watershed. After modelling the rainfall runoff relation and studying the availability of water at the Holetta River, the water demand of the area assessed. CropWat model and the survey analysis performed to calculate the water demand in the area. The total water demand of all three major users was 0.313, 0.583, 1.004, 0.873 and 0.341 MCM from January to May, respectively. The available river flow from January to May obtained from the result of SWAT simulation. The average flow was 0.749, 0.419, 0.829, 0.623 and 0.471 MCM from January to May respectively. From the five months, the demand and the supply showed a gap during February, March and April with 0.59 MCM. Therefore, in order to solve this problem alternative source of water supply should be studied and integrated water management system should be implemented

Formulation of complementary food using amaranth, chickpea and maize improves iron, calcium and zinc content

Malnutrition is the cause of the majority of deaths in children under five years old in Ethiopia. Micronutrient deficiencies such as iron, zinc and calcium, often seen in malnourished children, are major public health problems throughout Ethiopia. These deficiencies have negative consequences on the cognitive and physical development of children, and on work productivity of adults. There is, therefore, a need for sustainable methods to address iron inadequacy in complementary feeding. Animal products are a good source of iron, zinc and calcium, but due to their high costs, their consumption by most children in Ethiopia has declined. The grain amaranth grows wild in areas of Ethiopia but is considered a weed. This study, conducted in rural Ethiopia, was initiated to prepare nutrient-rich complementary food using recipes that substituted the usual maize gruel with porridge made from amaranth and chickpea flours. Using a laboratory based experimental study design, four porridges suitable for complementary feeding, with different proportions of amaranth grains, maize and chickpeas were formulated in triplicate and analyzed in triplicate for minerals including iron, and phytate levels. Mother-child pairs were recruited for acceptability testing, at the community level. Results showed adding amaranth improved the content of iron and other nutrients as compared to control porridge (100% maize) and decreased phytate levels. The lowest phytate to iron ratio (0.24) was observed in the 70% amaranth and 30% chickpea blend, and the lowest viscosity measure was also observed in this same formulation. Soaking amaranth seeds in warm (50oC) water then germinating in lemon juice-containing water at 32oC for 72 hours resulted in the lowest phytate levels. In sensory testing, all of the formulated porridges with different proportions of amaranth flour were acceptable to mothers and their children, although the red color was disliked by mothers and their children. Flavor preference was not altered; however, overall acceptability was reduced with increasing amounts of amaranth. The study indicated that a processed 70% amaranth and 30% chickpea product can be used to produce low-cost, nutrient-rich complementary food with moderate acceptability. Increased nutritional awareness, production and consumption of grain amaranth products may be the way to address mineral deficiencies including iron, in the study area.Keywords: Micronutrients, Phytates, Complementary feeding, Amaranth grain, Chickpea, Ethiopia, Iron, Zinc

Clinico-pathological Diagnosis of Facioscapulohumeral Dystrophy in a 22-year-old Male

Background: Facioscapulohumeral dystrophy (FSHD) is a rare hereditary disease with a prevalence of 2.03–6.8 per 100,000 individuals. FSHD is the third most common type of muscular dystrophy after the Duchene muscular dystrophy and myotonic dystrophy. To the best of our knowledge, the current case report is the first to report probable FSHD case mainly diagnosed using clinico-pathological evidence from sub-Saharan Africa (SSA). Case Report: A 22-year-old right-handed male college student presented with progressive proximal muscular weakness associated with wasting. The weakness started from the bilateral facial muscles and progressively involved proximal upper and lower limbs muscles associated with scapular winging, waddling gait, and bilateral foot drops. His bulbar, sensory, autonomic, and cognitive systems were spared. Muscles EMG showed myopathic patterns and normal serum CK. Muscle biopsy from affected muscles showed variation in fiber size with groups of angular fibers, preserved fibers, and hypertrophic fibers with marked fibrosis and adipose tissue replacement with no apparent inflammation and necrosis which is consistent with pathological features of muscular dystrophy. Considering the clinical semiology, physical findings, EMG findings, and pathological findings diagnosis of FSHD of scapuloperoneal variant was made. The patient was managed with analgesics, nutritional advice, and ankle prosthesis for foot drops. Currently, the patient is in a similar condition with modest improvement in his musculoskeletal pain complaints. Conclusion: This case highlights the fact that a careful clinical evaluation with thorough utilization of diagnostic investigations available at our disposal may support the diagnosis of FSHD in resource-limited areas where the necessary genetic tests were not available.
