Groundwater Suitability for Irrigation: a Case Study from Debre Kidane Watershed, Eastern Tigray, Ethiopia

The present paper tries to assess groundwater suitability for irrigation purpose in Debre Kidane Watershed (45.09 km2), northern Ethiopia. The goal was to evaluate the suitability of the groundwater for irrigation, examine the water types and to investigate possible long and short term impact on groundwater quality. Thirty six water samples each were collected in rainy and dry (irrigation) seasons from the active shallow hand dug wells. The well selection for detailed study and water sampling was done using stratified followed by random sampling technique. The number of wells selected for study is accounting 10% of the total available hand dug wells in the area. Parameters such as electrical conductivity (EC), pH, Total Dissolved Solids (TDS), temperature and other physical properties were recorded in the field. Major anions and cations (Ca2+, Mg2+, K+, Na+, CO32-, HCO3-, Cl-, SO42- and NO3-) were analyzed in the laboratory. Chemical data suggests that the water type in the area though varies from Mg-HCO3, Ca-HCO3, Mg-Cl, Na-HCO3 to K- HCO3, predominantly it is mixed cation-HCO3 type in the rainy season; and Ca-HCO3 (Piper diagram) and Na-HCO3 (Stiff diagram) in irrigation season. Dominance of Na in irrigation season and increase in Sodium Absorption Ratio (SAR) are primarily due to possible increase of Na absorption in the soil replacing Ca. According to the guidelines for irrigation water quality, the groundwater is suitable for irrigation with some minor exceptions. In rainy season, 89% of the samples fall under the water class “good” and 11% “permissible” whereas in irrigation season only 30% are classified as “good” and 70% under “permissible” class. Toxicity in terms of SAR and salinity though presently under control and there is no specific toxicity effect on vegetables and field crops, however, there are indications of their increase in due course of time if proper measures are not taken.

Impact of child mortality and fertility preferences on fertility status in rural Ethiopia

Objectives: To determine the effects of child mortality and fertility preference on fertility status in rural Ethiopia. Design: Case-referent where the cases were women with number of children ever born alive was less than five and controls were women with number of children ever born alive greater or equal to five. Setting: Butajira rural health project study base which is a field epidemiologic laboratory found 35 Kms south of the capital city of Ethiopia, Addis Ababa run by the Department of Community Health of Tikur Anbessa Medical Faculty. Main outcome measures: Fertility status measured by number of children ever born alive; death of a child or an infant is a predictor. Subjects: A total of 219 women with number of children ever born alive less than five and 899 women with number of children ever born alive greater or equal to five were included in the study. Results: Child mortality affected number of children ever born alive significantly (OR= 7.39, 95% CI: 4.62, 9.08). As the number of children died increased proportionally, there is a proportional increase in the risk of higher fertility (X2 for trend 4.92, d.f =4, p-value 0.02). Number of children desired before marriage, desire for more children and sex preference were not associated with increased fertility in this study. Of all the socio-demographic and reproductive variables, later age at first marriage and first birth showed lower number of children ever born alive with (OR= 1.82, 95 % CI: 1.24, 2.83) and (OR= 3.08, 95 % Cl: 2.03, 4.68) respectively. Breast-feeding duration of more than six months showed association with less number of children ever born alive (OR= 1.92, 95% CI: 1.30,2.80). Conclusion: The study finding implies high fertility status is strongly associated with child death and hence measures that curb child mortality are believed to decrease fertility status besides promoting child survival.

Commercialization of vegetable production in Alamata Woreda, Northern Ethiopia: processes and impact

The Raya valley in Tigray where Alamata Woreda is located, has fertile soil, suitable climate and rich water resources to grow various crops including vegetables. Surface water from seasonal rivers/streams and small dams and ground water extracted from deep and shallow wells with various water lifting devices are the two main sources of water for irrigation in the Woreda. A participatory rural appraisal (PRA) study conducted by the Woreda stakeholders and facilitated by IPMS identified (irrigated) vegetables as a potential marketable commodity in 2005. Using the commodity value chain approach, production, input supply and marketing problems and opportunities were identified. Major problems were lack of interest partly as a result of market failure in the past, lack of agronomic and irrigation knowledge and skills resulting in lack of use of advanced agronomic inputs (e.g. seeds) and underutilization of modern irrigation facilitates (most of the deep wells established were not used and/or underutilized). Different extension approaches were used including study tours to change the mind-set and to acquire knowledge for experts and farmers. Following various production interventions, market linkages were created which resulted in better prices (from 0.70Birr/kg before 2005 to 3-5Birr/kg in the following years). Farmer to farmer communications, trainings, workshops and media coverage facilitated the further dissemination of knowledge and skills between PAs in Alamata and neighboring Woredas. As a result of these interventions, the area of irrigated onion, pepper and tomato tripled in size from 351 ha in 2004/05 to 1113 ha in 2008/09. The lion share of this increase was due to a ten fold increase in onion area from 84 ha in 2004/05 to 824 ha in 2008/09. Most of this increase took place in the spate irrigated areas where plots previously used for cereal crops (sorghum and teff) were converted to vegetables. Both women and men farmers benefited from the intervention. Many farmers managed to construct houses in town and were able to own different assets. The further expansion of the (irrigated) vegetable production in Alamata is feasible. However, more attention needs to be paid to improving productivity, especially in the spate irrigated areas since no clear evidence was found that area increase was accompanied by productivity increase, indicating lack of adequate institutional and farmers’ knowledge and skills. Also adverse weather conditions during the 2008 harvesting season, resulted in considerable crop spoilage and lower prices – indicating the risk associated with this commodity under rain-fed conditions. Finally, potential salinity problems should also be taken into account

Intestinal parasitic infection and nutritional status among school children in Angolela, Ethiopia

ntroduction. Gastrointestinal parasitic infections are most prevalent in populations with low household income, poor han- dling of personal and environmental sanitation, overcrowding, and limited access to clean water. We conducted this study to esti- mate the prevalence of parasitic infection and nutritional status, and to evaluate the extent to which the two are associated among schoolchildren in rural Ethiopia. Methods. This is a cross sectional study of 664 students aged from 6 to 19 years old from Angolela, Ethiopia. Socio-demo- graphic information was collected using a structured question- naire. Anthropometric measurements were taken at the time of interview. Examinations of fecal samples for helminthic and pro- tozoan parasitic infections were performed. Logistic regression procedures were employed to evaluate the association between stunting, underweightedness, and wasting with parasitic infec- tions. Results. One-third of the participants were found to have a protozoan infection, while 7.1% were found to have a helminhic infection. Approximately 11% of the students were stunted, 19.6% were wasted, and 20.8% were underweight. Severely underweight boys were 3.88-times as likely as boys of adequate weight (odds ratio OR = 3.88, 95% confidence interval CI: 1.12- 13.52) to be diagnosed with protozoan infections. Among girls, those who were severely stunted were approximately 12 times (OR = 11.84, 95%CI: 1.72-81.62) as likely to be infected with a helminthic parasite, than those who were not. Overall, there was a deficit in normal growth patterns as indicated by lower than average anthropometric measures. Discussion and conclusions. There is a high prevalence of intes- tinal parasitic infections. Stunting, wasting, and underweighted- ness were also prevalent, and showed patterns of associations with intestinal parasitic infections. Efforts should be made to strengthen and expand school and community-based programs that promote inexpensive, though effective, practices to prevent the spread of parasitic diseases. Initiatives aimed at improving the nutritional status of school children are also needed

Prevalence of Metabolic Syndrome among Working Adults in Ethiopia

Objective. To evaluate the prevalence of metabolic syndrome (MetS) according to the International Diabetes Federation (IDF) and Adult Treatment Panel (ATP) III criteria among working East African adults. Design. This cross-sectional study of 1,935 individuals (1,171 men and 764 women) was conducted among working adults in Addis Ababa, Ethiopia. The study was conducted in accordance with the STEPwise approach of the World Health Organization. Results. According to ATP III and IDF definitions, the overall prevalence of MetS was 12.5% and 17.9%, respectively. Using ATP III criteria, the prevalence of MetS was 10.0% in men and 16.2% in women. Application of the IDF criteria resulted in a MetS prevalence of 14.0% in men and 24.0% in women. The most common MetS components among women were reduced high-density lipoprotein-cholesterol (HDL-C) (23.2%) and abdominal obesity (19.6%); whilst reduced HDL-C concentrations (23.4%) and high blood pressure (21.8%) were most common among men. Conclusion. MetS and its individual components are prevalent among an apparently healthy working population in Ethiopia. These findings indicate the need for evidence-based health promotion and disease prevention programs; and more robust efforts directed towards the screening, diagnosis and management of MetS and its components among Ethiopian adults

Prevalence and Correlates of Mental Distress Among Working Adults in Ethiopia

Objective: To evaluate the prevalence of mental distress and its correlates among working Ethiopian adults. Methods: This cross-sectional study of 2,180 individuals (1,316 men and 864 women) was conducted among working adults in Addis Ababa, Ethiopia. A structured questionnaire was used to collect information on socio-demographic and lifestyle characteristics of participants. Mental distress was assessed using the self-reporting questionnaire (SRQ). Logistic regression was employed to estimate adjusted odds ratios (OR) and 95% confidence intervals (95% CI). Results: The prevalence of mental distress in the study sample was 17.7% (25.9% in women and 12.4% in men). Younger participants (age ≤24 years) had the highest prevalence of mental distress (35.5% in women and 16.7% in men). The odds of mental distress was 2.47-fold higher among women as compared with men (OR=2.47, 95% CI 1.97-3.09). Participants reporting excellent health status had a 50% reduced odds of mental distress (OR=0.47; 95%CI: 0.38-0.59); and moderate alcohol consumption was associated with a slight increased odds of mental distress (OR=1.26; 95%CI: 1.00-1.67). Conclusion: A high prevalence of mental distress was observed among working adults in Ethiopia. Our findings suggest that the workforce institutions should provide targeted prevention and intervention programs to improve the mental health state of their employees. National mental health policy that clearly outlines and addresses mental distress among working adults is also warranted

Vulnerability to episodes of extreme weather: Butajira, Ethiopia, 1998–1999

BACKGROUND: During 1999-2000, great parts of Ethiopia experienced a period of famine which was recognised internationally. The aim of this paper is to characterise the epidemiology of mortality of the period, making use of individual, longitudinal population-based data from the Butajira demographic surveillance site and rainfall data from a local site. METHODS: Vital statistics and household data were routinely collected in a cluster sample of 10 sub-communities in the Butajira district in central Ethiopia. These were supplemented by rainfall and agricultural data from the national reporting systems. RESULTS: Rainfall was high in 1998 and well below average in 1999 and 2000. In 1998, heavy rains continued from April into October, in 1999 the small rains failed and the big rains lasted into the harvesting period. For the years 1998-1999, the mortality rate was 24.5 per 1,000 person-years, compared with 10.2 in the remainder of the period 1997-2001. Mortality peaks reflect epidemics of malaria and diarrhoeal disease. During these peaks, mortality was significantly higher among the poorer. CONCLUSIONS: The analyses reveal a serious humanitarian crisis with the Butajira population during 1998-1999, which met the CDC guideline crisis definition of more than one death per 10,000 per day. No substantial humanitarian relief efforts were triggered, though from the results it seems likely that the poorest in the farming communities are as vulnerable as the pastoralists in the North and East of Ethiopia. Food insecurity and reliance on subsistence agriculture continue to be major issues in this and similar rural communities. Epidemics of traditional infectious diseases can still be devastating, given opportunities in nutritionally challenged populations with little access to health care

Can radiosensitivity associated with defects in DNA repair be overcome by mitochondrial-targeted antioxidant radioprotectors

Radiation oncologists have observed variation in normal tissue responses between patients in many instances with no apparent explanation. The association of clinical tissue radiosensitivity with specific genetic repair defects (Wegner's syndrome, Ataxia telangiectasia, Bloom's syndrome, and Fanconi anemia) has been well established, but there are unexplained differences between patients in the general population with respect to the intensity and rapidity of appearance of normal tissue toxicity including radiation dermatitis, oral cavity mucositis, esophagitis, as well as differences in response of normal tissues to standard analgesic or other palliative measures. Strategies for the use of clinical radioprotectors have included modalities designed to either prevent and/or palliate the consequences of radiosensitivity. Most prominently, modification of total dose, fraction size, or total time of treatment delivery has been necessary in many patients, but such modifications may reduce the likelihood of local control and/or radiocurability. As a model system in which to study potential radioprotection by mitochondrial-targeted antioxidant small molecules, we have studied cell lines and tissues from Fanconi anemia (Fancd2-/-) mice of two background strains (C57BL/6NHsd and FVB/N). Both were shown to be radiosensitive with respect to clonogenic survival curves of bone marrow stromal cells in culture and severity of oral cavity mucositis during single fraction or fractionated radiotherapy. Oral administration of the antioxidant GS-nitroxide, JP4-039, provided significant radioprotection, and also ameliorated distant bone marrow suppression (abscopal effect of irradiation) in Fancd2-/- mice. These data suggest that radiation protection by targeting the mitochondria may be of therapeutic benefit even in the setting of defects in the DNA repair process for irradiation-induced DNA double strand breaks. © 2014 Greenberger, Berhane, Shinde, Han Rhieu, Bernard, Wipf, Skoda and Epperly
