Trotter] is the major cultivated cereal crop in Ethiopia and serves as staple food grain for over 65% of the population. The area under tef cultivation is over three million hectares of land each year. Depending on the type of seed color, tef grains are categorized into white and brown, while some admixtures and intermediate seed colors also exist. However, the productivity of tef is very low as compared to other cereals due, among others, to lack of high yielding varieties. The objective of this study was to evaluate the performance of released brown seeded tef variety called Felagot and to provide unique morphological and agronomic descriptions of this new variety. Twelve genotypes resulting from two independent crossesnd breed for at least seven generations plus local and standard check varieties were tested over two years (2014 and 2015 main season) at six tef growing locations namely: Debre Zeit light soil, Debre Zeit Black soil, Minjar, Adet, Bichena and Holetta using randomized complete block design with four replications. The study found that Felagot (DZ-Cr-442/ RIL-77C) which was obtained from a cross between Quncho (the popular variety) and Gea Lammie (local cultivar) exceled the other genotypes and it was approved for release by the Ethiopian National Variety Release Committee in March 2017. The main advantages of Felagot over the other tested lines were its higher grain yield together with high straw yield and brown seed color. In addition, it was released under the brown seed category after one and half decades. Furthermore, it is anticipated that because of the brown seed color Felagot will command high external market preferences and prices, and thereby contribute for future tef export market

However, the productivity of the crop remains low mainly due to the limited use of improved technologies including seeds. In this study, three recently released and one old (as a check) tef varieties were evaluated on 254 lead farmers’ fields with the main aim of increasing farmers’ access to quality breed seeds.Each lead farmer was provided with breeder seeds of four improved tef varieties, namely Kora, Tesfa, Dagim, and Boset.The seed yield from the four tef varieties were comparable (Kora = 1.94, Tesfa = 2.31, Dagim =2.24 and Boset = 2.36 t ha-1). Given the input and output prices that prevail in the selected districts, the mean revenue was 65,355.90 Birr ha-1 while the mean production cost was 26,355.52 Birr ha-1. Among production costs, labor took for the lion’s share as it contributed to 58% of the total cost.   In general, with a benefit-cost ratio of 1.5, our technology is highly profitable and attractive to farmers if newly released tef varieties are disseminated in the seed-business-oriented method. &nbsp

    As mortality rates decline, life expectancy increases, and populations age, non-fatal outcomes of diseases and injuries are becoming a larger component of the global burden of disease. The Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) provides a comprehensive assessment of prevalence, incidence, and years lived with disability (YLDs) for 328 causes in 195 countries and territories from 1990 to 2016

    BACKGROUND: Detailed assessments of mortality patterns, particularly age-specific mortality, represent a crucial input that enables health systems to target interventions to specific populations. Understanding how all-cause mortality has changed with respect to development status can identify exemplars for best practice. To accomplish this, the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 (GBD 2016) estimated age-specific and sex-specific all-cause mortality between 1970 and 2016 for 195 countries and territories and at the subnational level for the five countries with a population greater than 200 million in 2016. METHODS: We have evaluated how well civil registration systems captured deaths using a set of demographic methods called death distribution methods for adults and from consideration of survey and census data for children younger than 5 years. We generated an overall assessment of completeness of registration of deaths by dividing registered deaths in each location-year by our estimate of all-age deaths generated from our overall estimation process. For 163 locations, including subnational units in countries with a population greater than 200 million with complete vital registration (VR) systems, our estimates were largely driven by the observed data, with corrections for small fluctuations in numbers and estimation for recent years where there were lags in data reporting (lags were variable by location, generally between 1 year and 6 years). For other locations, we took advantage of different data sources available to measure under-5 mortality rates (U5MR) using complete birth histories, summary birth histories, and incomplete VR with adjustments; we measured adult mortality rate (the probability of death in individuals aged 15-60 years) using adjusted incomplete VR, sibling histories, and household death recall. We used the U5MR and adult mortality rate, together with crude death rate due to HIV in the GBD model life table system, to estimate age-specific and sex-specific death rates for each location-year. Using various international databases, we identified fatal discontinuities, which we defined as increases in the death rate of more than one death per million, resulting from conflict and terrorism, natural disasters, major transport or technological accidents, and a subset of epidemic infectious diseases; these were added to estimates in the relevant years. In 47 countries with an identified peak adult prevalence for HIV/AIDS of more than 0·5% and where VR systems were less than 65% complete, we informed our estimates of age-sex-specific mortality using the Estimation and Projection Package (EPP)-Spectrum model fitted to national HIV/AIDS prevalence surveys and antenatal clinic serosurveillance systems. We estimated stillbirths, early neonatal, late neonatal, and childhood mortality using both survey and VR data in spatiotemporal Gaussian process regression models. We estimated abridged life tables for all location-years using age-specific death rates. We grouped locations into development quintiles based on the Socio-demographic Index (SDI) and analysed mortality trends by quintile. Using spline regression, we estimated the expected mortality rate for each age-sex group as a function of SDI. We identified countries with higher life expectancy than expected by comparing observed life expectancy to anticipated life expectancy on the basis of development status alone. FINDINGS: Completeness in the registration of deaths increased from 28% in 1970 to a peak of 45% in 2013; completeness was lower after 2013 because of lags in reporting. Total deaths in children younger than 5 years decreased from 1970 to 2016, and slower decreases occurred at ages 5-24 years. By contrast, numbers of adult deaths increased in each 5-year age bracket above the age of 25 years. The distribution of annualised rates of change in age-specific mortality rate differed over the period 2000 to 2016 compared with earlier decades: increasing annualised rates of change were less frequent, although rising annualised rates of change still occurred in some locations, particularly for adolescent and younger adult age groups. Rates of stillbirths and under-5 mortality both decreased globally from 1970. Evidence for global convergence of death rates was mixed; although the absolute difference between age-standardised death rates narrowed between countries at the lowest and highest levels of SDI, the ratio of these death rates-a measure of relative inequality-increased slightly. There was a strong shift between 1970 and 2016 toward higher life expectancy, most noticeably at higher levels of SDI. Among countries with populations greater than 1 million in 2016, life expectancy at birth was highest for women in Japan, at 86·9 years (95% UI 86·7-87·2), and for men in Singapore, at 81·3 years (78·8-83·7) in 2016. Male life expectancy was generally lower than female life expectancy between 1970 and 2016, an

    Global, regional, and national disability-adjusted life-years (DALYs) for 333 diseases and injuries and healthy life expectancy (HALE) for 195 countries and territories, 1990–2016: a systematic analysis for the Global Burden of Disease Study 2016

    BACKGROUND: Measurement of changes in health across locations is useful to compare and contrast changing epidemiological patterns against health system performance and identify specific needs for resource allocation in research, policy development, and programme decision making. Using the Global Burden of Diseases, Injuries, and Risk Factors Study 2016, we drew from two widely used summary measures to monitor such changes in population health: disability-adjusted life-years (DALYs) and healthy life expectancy (HALE). We used these measures to track trends and benchmark progress compared with expected trends on the basis of the Socio-demographic Index (SDI). METHODS: We used results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2016 for all-cause mortality, cause-specific mortality, and non-fatal disease burden to derive HALE and DALYs by sex for 195 countries and territories from 1990 to 2016. We calculated DALYs by summing years of life lost and years of life lived with disability for each location, age group, sex, and year. We estimated HALE using age-specific death rates and years of life lived with disability per capita. We explored how DALYs and HALE differed from expected trends when compared with the SDI: the geometric mean of income per person, educational attainment in the population older than age 15 years, and total fertility rate. FINDINGS: The highest globally observed HALE at birth for both women and men was in Singapore, at 75·2 years (95% uncertainty interval 71·9-78·6) for females and 72·0 years (68·8-75·1) for males. The lowest for females was in the Central African Republic (45·6 years [42·0-49·5]) and for males was in Lesotho (41·5 years [39·0-44·0]). From 1990 to 2016, global HALE increased by an average of 6·24 years (5·97-6·48) for both sexes combined. Global HALE increased by 6·04 years (5·74-6·27) for males and 6·49 years (6·08-6·77) for females, whereas HALE at age 65 years increased by 1·78 years (1·61-1·93) for males and 1·96 years (1·69-2·13) for females. Total global DALYs remained largely unchanged from 1990 to 2016 (-2·3% [-5·9 to 0·9]), with decreases in communicable, maternal, neonatal, and nutritional (CMNN) disease DALYs offset by increased DALYs due to non-communicable diseases (NCDs). The exemplars, calculated as the five lowest ratios of observed to expected age-standardised DALY rates in 2016, were Nicaragua, Costa Rica, the Maldives, Peru, and Israel. The leading three causes of DALYs globally were ischaemic heart disease, cerebrovascular disease, and lower respiratory infections, comprising 16·1% of all DALYs. Total DALYs and age-standardised DALY rates due to most CMNN causes decreased from 1990 to 2016. Conversely, the total DALY burden rose for most NCDs; however, age-standardised DALY rates due to NCDs declined globally. INTERPRETATION: At a global level, DALYs and HALE continue to show improvements. At the same time, we observe that many populations are facing growing functional health loss. Rising SDI was associated with increases in cumulative years of life lived with disability and decreases in CMNN DALYs offset by increased NCD DALYs. Relative compression of morbidity highlights the importance of continued health interventions, which has changed in most locations in pace with the gross domestic product per person, education, and family planning. The analysis of DALYs and HALE and their relationship to SDI represents a robust framework with which to benchmark location-specific health performance. Country-specific drivers of disease burden, particularly for causes with higher-than-expected DALYs, should inform health policies, health system improvement initiatives, targeted prevention efforts, and development assistance for health, including financial and research investments for all countries, regardless of their level of sociodemographic development. The presence of countries that substantially outperform others suggests the need for increased scrutiny for proven examples of best practices, which can help to extend gains, whereas the presence of underperforming countries suggests the need for devotion of extra attention to health systems that need more robust support.

    Economic Valuation of Lake Tana: A Recreational Use Value Estimation through the Travel Cost Method

    No full text
    Lake Tana is a well-known tourist spot in northern Ethiopia that lures both domestic and foreign tourists. The lake’s value is still underrated, despite the site’s immense potential for recreation and tourism. In this study, the recreational value of Lake Tana is estimated, and the consumer characteristics associated with recreational demand are analyzed. The study employs a Zero-Truncated Poisson (ZTP) regression model for data generated by the Individual Travel Cost Method (ITCM) and draws information from 1094 on-site surveys. According to ZTP regression results, variables that are significantly and positively associated with demand for Lake Tana recreation include the monthly income and age of the visitors and their preference for other recreation destinations such as Tis-Abay and Gondar Fasiledes Royal Castle. However, respondents’ leisure time, overall cost, and residential distance from the recreational site are all negatively associated with the demand for recreation. It is also evident that Lake Tana is endowed with a wealth of attributes, ranging from natural beauty to ancient religious and cultural heritages, making the lake a highly desirable recreation destination. According to the estimation, Lake Tana has a yearly recreational value of around USD 68.5 million. However, it also demonstrates that if lake settings were to improve in quality, the value of Lake Tana would rise considerably, reaching USD 151 million. The value of sentimental attachment implies that determining Lake Tana’s recreational value is a key element in the resource’s sustainable utilization and management. To make greater use of Lake Tana’s recreational amenities, however, uncontrolled waste disposal, favorable recreation facilities, and the spread of water hyacinth should be addressed immediately. Furthermore, it is imperative to maintain the lake’s diverse attributes, as the integration of these attributes is what gives the lake its primary appeal

    Individual- and Community-Level Risk Factors Associated with Childhood Diarrhea in Ethiopia: A Multilevel Analysis of 2016 Ethiopia Demographic and Health Survey

    No full text
    Background. Diarrhea is the second cause of child deaths globally. According to World Health Organization reports, in each year, it kills more than 525,000 children under 5 years. More than half of these deaths occur in five countries including Ethiopia. This study is aimed at identifying both individual- and community-level risk factors of childhood diarrhea in Ethiopia. Methods. Ethiopian demography and health survey of 2016 data were used for the analysis. A total of 10,641 children aged 0–59 months were included in the analysis. A multilevel mixed-effects logistic regression model was used to identify both individual- and community-level risk factors associated with childhood diarrhea. Result. The incidence of childhood diarrhea was 12% (95% CI: 11.39, 12.63). The random-effects model revealed that 67% of the variability of childhood diarrhea was explained by individual- and community-level factors. From the individual-level factors, children aged 36–59 months (AOR=3.166; 95% CI: 2.569, 3.900), twin child (AOR=1.871; 95% CI: 1.390, 2.527), birth order 5 and above (AOR=2.210, 95% CI: 1.721, 2.839), not received any vaccination (AOR=1.197; 95% CI: 1.190, 1.527), smaller size of child at birth (AOR=1.303; 95% CI: 1.130, 1.504), and never breastfed children (AOR=2.91; 95% CI: 2.380, 3.567) associated with the higher incidence of childhood diarrhea. From the community-level factors, living in a rural area (AOR=1.505; 95% CI: 1.233, 1.836)), unprotected source of drinking water (AOR=1.289; 95% CI: 1.060, 1.567), and availability of unimproved latrine facilities (OR: 1.289; 95% CI: 1.239, 1.759) associated with the higher incidence of childhood diarrhea. Besides, children who live in Afar, Amhara, Benishangul-Gumuz, Gambella, SNNPR, and Dire Dawa regions had higher incidence of childhood diarrhea. Conclusion. The incidence of childhood diarrhea was different from cluster to cluster in Ethiopia. Therefore, integrated child health intervention programs including provisions of toilet facility, access to a clean source of drinking water, educate parents about the importance of breastfeeding, and vaccination have to be strongly implemented in order to reduce the high incidence of childhood diarrhea among children in Ethiopia
