Analysis of the nutritional and antinutritional contents of tubers of Agew potatoes (Plectranthus edulis) grown in the Awi Zone, Amhara regional state of Ethiopia

Plectranthus edulis is one of the most important tuberous plants, is an indigenous plant, and grows in middle- and high-altitude areas. This study investigated the proximate, antinutritional, antioxidant, and mineral compositions of P. edulis (Agew potato) grown in the Dangila, Ankesha, and Banja districts in the Awi zone of the Amhara region, Ethiopia. The proximate composition was determined via the Association of Official Analytical Chemists (AOAC) protocol. The moisture, ash, crude fat, crude protein, crude fiber, carbohydrate, phytate, tannin, TPC, TFC, and DPPH assay results ranged from 70.87 to 74.92 g/100 g, 3.92–4.58 g/10 g, 0.36–0.61 g/100 g, 6.86–9.29 g/100 g, 3.18–3.56 g/100 g, 71.79–78.81 g/100 g, 61.48–108.04 mg/100 g, 8.46–44.15 mg/100 g, 17.53–28.42 mg/g, 2.75–5.71 mg/g, and 52.94–71.49%, respectively. The concentrations of Na, P, Fe, Cu, and Zn ranged from 261.85 to 603.90 mg/kg, 82.02–251.82 mg/100 g, 23.74–65.36 mg/kg, 9.98–16.27 mg/kg, and 17.68–30.20 mg/kg, respectively. The Agew potato from Dangila had a better nutritional content than Banja and Ankesha. Agew potatoes are nutritious and medically important tuber plants used to secure food, especially in undernourished societies.

“A quantitative analysis on the adoption of soil, water, and forest conservation technologies in the upper Gelana watershed, Northeast Ethiopian highlands”

Globally, the degradation of soil, water, and forests has had a significant impact on both livelihoods and the environment. This issue is particularly severe in developing countries, including Ethiopia. Despite extensive efforts to implement conservation measures for soil, water, and forests in the highlands of Ethiopia, there has been a lack of thorough evaluation and documentation regarding the adoption of these practices by rural households. It is crucial to have scientific and up-to-date information at various spatial scales in order to effectively monitor existing practices, scale up successful initiatives, and promote sustainable regional development. Therefore, this paper focuses on analyzing the adoption of soil, water, and forest conservation activities by households in the upper Gelana watershed, South Wollo zone, Amhara Regional State of Ethiopia. The field data collection for this study took place from January to March 2022, from 150 rural household heads. Data analysis was carried out using SPSS software version 23. Descriptive statistics, Pearson bivariate correlation, and multinomial logistic regression were used. The survey findings revealed that 69 % of the respondents had implemented various soil, water, and forest conservation measures at different stages. The Pearson correlation results indicated a positive relationship between the adoption of soil, water and forest conservation practices. The multinomial logistic regression analysis has revealed that age, gender, access to credit, and access to extension services, significantly influenced the households’ decision behaviour to adopt soil conservation practices. Age, access to extension service, and access to water resource were significant predictors of adoption of water conservation practices; whereas age, educational status, and access to extension service were significant predictors of adoption of forest conservation practices. This study underscores the significance of institutional factors in driving the adoption of technology in the research area. It further recommends policies that prioritize the dissemination of information on effective strategies, improvement of access to extension services, water resources, and credit facilities to promote sustainable watershed management. This study is exceptional in its innovative approach, which explores the convergence of these vital conservation domains within the distinct setting of the upper Gelana watershed. Studying the adoption of these technologies is crucial for informing policy-making and designing effective interventions that promote sustainable watershed practices. In this case, the Ministry of Agriculture, and development agents should scale up the adoption of these practices and take remedial actions for those not yet adopted.

Vectorial drivers of malaria transmission in Jabi Tehnan district, Amhara Regional State, Ethiopia

Among the factors affecting the effectiveness of malaria control is poor knowledge of the entomologic drivers of the disease. We investigated anopheline populations as part of a baseline study to implement house screening of windows and doors as a supplementary malaria control tool towards elimination in Jabi Tehnan district, Amhara Regional State of Ethiopia. The samples were surveyed monthly using CDC light traps between June 2020 and May 2021. Mosquito trap density (< 3 mosquitoes/trap) was low, however, with a high overall Plasmodium sporozoite rate (9%; indoor = 4.3%, outdoor = 13.1%) comprising P. falciparum (88.9%) and P. vivax (11.1%). Anopheles gambiae s.l., mostly An. arabiensis, comprised > 80% of total anopheline captures and contributed ~ 42% of Plasmodium-infected mosquitoes. On the other hand, morphologically scored Anopheles funestus s.l., constituting about 6% of anopheline collections, accounted for 50% of sporozoite-infected mosquitoes. Most of the infected An. funestus s.l. specimens (86.7%) were grouped with previously unknown or undescribed Anopheles species previously implicated as a cryptic malaria vector in the western Kenyan highlands, confirming its wider geographic distribution in eastern Africa. Other species with Plasmodium infection included An. longipalpis C, An. theileri, An. demillioni, and An. nili. Cumulatively, 77.8% of the infected mosquitoes occurred outdoors. These results suggest efficient malaria parasite transmission despite the low vector densities, which has implications for effective endpoint indicators to monitor malaria control progress. Additionally, the largely outdoor infection and discovery of previously unknown and cryptic vectors suggest an increased risk of residual malaria transmission and, thus, a constraint on effective malaria prevention and control.

Characterization of Cattle Production System in East Gojjam Zone of Amhara Regional State, Ethiopia

Survey was conducted in four Districts of East Gojjam Zone Amhara Regional state of Ethiopia (Sinan, Dejen, Gozamen and Machakel). The objectives of the survey were to characterize cattle production systems, asses feed resources of cattle in eastern Gojjam and identify major constraint of cattle production in the zone. A total of 160 household heads were randomly selected and interviewed using a structured questionnaire. The study revealed that the average cattle herd size was 7.55 ± 0.31 heads per household and were significantly different (P&amp;lt;0.01) among districts. In the study districts, cattle are primarily kept for draught power followed by income source and milk production. According to the respondents, crop residue, hay and local brewery by-products are the main feed resources ranked in order of importance as first, second and third, respectively in dry season. Similarly, crop residue, cut and curry system and communal grazing are important feed sources in wet season (ranked as first, second and third, respectively). The study also shows that feed shortage was the main constraint affecting livestock production and productivity across the districts. In availability of appropriate cattle genotype and disease were identified as second and third important constraints. Due to shrinkage of grazing areas, farmers are shifting cattle rearing from permanent free grazing into tethering and semi-grazing systems. The total livestock number in the zone was estimated to be 7.55 TLU unit which is directly related to carrying capacity of the grazing feed resources in the area. Thus, the study implies that there is a need to improve fodder production, crop residue utilization, efficiency and utilization of artificial insemination to increase the number of improved cattle genotype and improve delivery of veterinary services in a smallholder cattle production system of the zone.

Testing CORDEX GCMs for Projecting Rainfall in Amhara, Ethiopia

Five CORDEX Global Circulation Models (GCMs): ICHEC-EC-EARTH, MIROC5, HadGEM2-ES, MPI-ESM-LR, and NorESM1-M were tested and validated for projecting rainfall in the Amhara regional state of Ethiopia. The GCMs were evaluated in terms of their performance during the historical period 1981-2020 and of the near-term, mid-term, and long-term future periods in three Representative Concentration Pathway (RCP) scenarios, RCP2.6, RCP4.5, and RCP8.5, across 71 grid points. Monthly observed rainfall data was used to compare the GCMs' performance and correct their biases using three non-parametric quartile mapping methods: robust empirical quartiles, empirical quartiles, and smoothing splines. The results show that HadGEM2-ES and MPI-ESM-LR had the best performance in the study area. The test and validation results for these two GCMs have come up with r = 0.8, NSE = 0.5-0.6, and RMSE = 64-70 mm/month. As there was a large discrepancy in historical and projected CORDEX rainfall data, bias correction was necessary, and the robust empirical quartiles method was found the best for the Amhara region. Compared to the historical, there will be a decrease in the monthly rainfall amount for the months of March, May, June, July, and October and an increase for the rest in all projected scenarios. The result concluded that using an ensemble of HadGEM2-ES &amp; MPI-ESM-LR GCMs would better simulate the rainfall in the Amhara region

Factors affecting onion production: An empirical study in the Raya Kobo district, Amhara regional state, Ethiopia.

Onion is a vital vegetable crop in Ethiopia, with significant economic and health benefits. However, its production trend is not consistent, with periods of increase and decrease; and its productivity in the country falls far below its potential. As a result, farmers are not yet fully benefited from onion production. Thus, this study was initiated to identify the factors influencing onion production in the Raya Kobo District of Amhara Regional State of Ethiopia. Data was collected from 189 onion-producing farmers through household surveys, and both descriptive and econometric techniques were used for analysis. The study found significant variation in onion production among farmers, with lower levels compared to national and international averages. Factors such as gender, education level, experience, labor force, land size, access to extension services, irrigation water, land plough frequency, and fertilizer availability positively impact onion production. However, excessive fertilizer use was found to have a negative effect. The study also identified challenges faced by farmers, including input shortages, high costs, diseases, labor issues, soil infertility, and storage knowledge gaps. The study recommends policymakers and stakeholders to utilize these findings to develop effective policies and interventions that can enhance onion production, benefiting farmers and improving the overall onion production.

Microbial, physicochemical and proximate analysis of Tej collected from Amhara regional state of Ethiopia

Tej is an Ethiopian traditional alcoholic beverage with significant social and economic importance. Due to the spontaneous fermentation process of Tej, several issues such as safety, quality, and physicochemical properties of the final products is rquired to be assessed. Thus, this study was aimed to assess the microbial quality, physicochemical, and proximate properties of Tej associated with different maturity time. The microbial, physicochemical and proximate analyses were carried out by standard protocol. Lactic acid bacteria (6.30 log CFU/mL) and yeast (6.22 log CFU/mL) were the dominat microorganisms of all Tej samples at different maturity time, with significant differences (p = 0.001) in mean microbial count among samples. The mean pH, titratable acidity and ethanol content of Tej samples were 3.51, 0.79 and 11.04% (v/v), respectively. There were significant differences (p = 0.001) among the mean pH and titratable acidity values. The mean proximate compositions (%) of Tej samples were as follows: moisture (91.88), ash (0.65), protein (1.38), fat (0.47) and carbohydrate (3.91). Statistically significant differences (p = 0.001) were observed in proximate compositions of Tej samples from different maturity time. Generally, Tej maturity time has a great impact on the improvement of nutrient composition and the increment of the acidic contents which in turn suppress the growth of unwanted microorganisms. Further evaluation of the biological, and chemical safety and development of yeast-LAB starter culture are strongly recommended to improve Tej fermentation in Ethiopia.

Ethiopian Voluntary Resettlement Programme-Lesson to Learn

The basic right of people in any society is earning a livelihood, and providing or fulfilling this requirement is a prime duty of the concerned government. Acting towards this end the democratic government of Ethiopia (African continent) has recently launched a resettlement program. The main objective of this study is to provide an overall view of the resettlement program in Bamluk and Sawatamp settlement sites, Jawi district, Amhara Regional State of Ethiopia. A qualitative method of analysis was employed for conducting this study. The informants at the household level were randomly selected to give the possible representative information. Key informants interviews and focus group discussions with resettlers and government representatives at district and zonal levels were held. The study revealed that there is a gap between the program document and its implementation on the ground. There was no consistency with the pillars, key principles, and approaches in the program document. The resettlement’s adverse consequences were the lack of proper preparation. The study indicates that the establishment of infrastructure and social services before the resettlement program are below the minimum standard and the services have not yet been improved in the area. Moreover, small land holdings and the risk of exposure to malaria contributed to the failure of the program. This reveals that the implementation of the resettlement program in the area is very weak.

Intention to use wearable health devices and its predictors among diabetes mellitus patients in Amhara region referral hospitals, Ethiopia: Using modified UTAUT-2 model

IntroductionThe burden of diabetes mellitus is increasing in Africa. Wearables have a proven track record of combating chronic diseases. However, little is known about patients’ intentions to use such technologies in resource-limited settings. Therefore, this study aimed to assess DM patients' intentions to use wearable health devices and its predictors in Ethiopia. MethodsAn institutional-based cross-sectional study was conducted among 924 diabetes mellitus patients from May 19 to June 23, 2022, at referral hospitals in the Amhara regional state of Ethiopia. An interviewer-administered questionnaire was used to collect the data using the Kobo Collect app. A systematic random sampling technique was used to select the study participants. Descriptive statistics were done using SPSS version 25 software and presented using tables and pie charts. Structural equation modeling analysis with SPSS AMOS version 26 software was employed to identify predictors associated with the intention to use wearable health devices in Ethiopia. ResultsA total of 883 diabetes mellitus patients, with a 95.56% response rate, participated in the study. The proportion of intention to use wearable health devices was 47.1%, 95% CI (43.7–50.5). Effort expectancy (β = 0.543, P < 0.01), performance expectancy (β = 0.306, P < 0.01), facilitating condition (β = 0.131, P < 0.05), and habit (β = 0.093, P < 0.05) had a positive direct relationship with intention to use wearable health devices. Age (β = 0.439, p < 0.001) was moderate performance expectancy, while gender (β = 0.780, p < 0.001) had moderate effort expectancy to the intention to use wearable health devices. ConclusionsOverall, diabetes mellitus patients’ intentions to use wearable health devices were promising. The intention to use wearables was positively related to effort expectancy, performance expectancy, facilitating conditions, and habit. Thus, increasing patient intention to utilize it could be achieved through capacity building, access to technology, and technical support. In addition, implementers should prioritize improving the availability of devices, patients' abilities, encouraging customers, to utilize the product on a regular basis by actively fostering their relationship with them, and create awareness about usefulness of wearable health devices.

Role of community pharmacy professionals in child health service provision in Ethiopia: a cross-sectional survey in six cities of Amhara regional state

BackgroundCommunity pharmacy professionals have great potential to deliver various public health services aimed at improving service access, particularly in countries with a shortage of health professionals. However, little is known about their involvement in child health service provision in Ethiopia.ObjectiveThe purpose of this study was to evaluate the level of involvement of community pharmacy professionals in child health service provision within Ethiopia.MethodsA multi-center cross-sectional survey was conducted among 238 community pharmacy professionals from March to July 2020 in Amhara regional state of Ethiopia. Independent samples t-test and one way Analysis of Variance (ANOVA) was used to test the mean difference.ResultsMost community pharmacy professionals were ‘involved’ in providing child health services related to ‘advice about vitamins/supplements’ (46.6%), ‘advice about infant milk/formulas’ (47.1%) and ‘responding to minor symptoms’ (50.8%) for children. The survey revealed that, community pharmacy professionals were less frequently involved in providing childhood ‘vaccination’ services. Further, level of involvement of community pharmacy professionals differed according to participants’ licensure level, setting type, responsibility in the facility and previous training experience in child health services.ConclusionCommunity pharmacy professionals have been delivering various levels of child health services, demonstrating ability and capacity in improving access to child health services in Ethiopia. However, there is a need for training and government support to optimize pharmacist engagement and contribution to service delivery.

Adherence to Covid-19 mitigation measures and its associated factors among health care workers at referral hospitals in Amhara regional state of Ethiopia.

With fragile health care systems, sub-Saharan Africa countries like Ethiopia are facing a complex epidemic, and become difficult to control the noble coronavirus. The use of COVID-19 preventive measures is strongly recommended. This study aimed to assess the adherence of COVID-19 mitigation measures and associated factors among health care workers. A facility-based cross-sectional study was conducted among health care workers at referral hospitals in the Amhara regional state of Ethiopia from May 15 to June 10; 2021. It was a web-based study using an online questionnaire. STATA 14.2 was used for data analysis. Variables with a p-value<0.05 at 95% confidence level in multivariable analysis were declared as statistically significant using binary logistic regression. Adherence to COVID-19 mitigation measures was 50.24% in the current study. The odd of adherence of participants with a monthly income of ≥12801birr was 15% whereas the odds of adherence of participants who hesitate to take the COVID 19 vaccine were 10% as compared to those who don't hesitate. Participants who had undergone COVID-19 tests adhered 6.64 times more than their counterparts. Those who believe adequate measurements are taken by the government adhered 4.6 times more than those who believe not adequate. Participants who believe as no risk of severe disease adhered 16% compared to those with fear of severe disease. Presence of households aged >60years adhered about 7.9 times more than with no households aged>60. Participants suspected of COVID-19 diagnosis adhered 5.7 times more than those not suspected. In this study, a significant proportion of healthcare workers did not adhere to COVID-19 mitigation measures. Hence, giving special attention to healthcare workers with a monthly income of ≥12801 birr, being hesitant towards COVID-19 vaccine, being aged 26-30, and perceiving no risk of developing a severe infection is crucial to reduce non-adherence.

GIS-based landslide susceptibility zonation and risk assessment in complex landscape: A case of Beshilo watershed, northern Ethiopia

Landslides necessitate comprehensive prediction of susceptible zones for timely intervention to mitigate any disaster. Present study at Beshilo-watershed in Amhara Regional State of Ethiopia was attempted to prepare landslide susceptibility zonation (LSZ) map and to carry out risk assessment. GIS-based multi-criteria decision analysis was adopted by considering factors; land-use/land-cover, slope, elevation, aspect, drainage-density, rainfall, lithology, lineament/fault density, soil depth, and texture. Factor weights were determined through Analytical Hierarchy Process (AHP) and the factor classes rating were assigned through logical judgment. Landslide susceptibility indices were determined based on a continuous numerical scale developed for this purpose. Very high and high susceptibility zones were found to spread in 1215.28 km2 and 2279.87 km2, respectively in the eastern and north-eastern parts that are characterized by high lineament/fault density, barren lands, shrubs, bushes, grassland, or croplands mostly having unconsolidated soils with shallow depth. The Receiver Operating Characteristics (ROC) curve showed acceptable results. Further, risk assessment indicated that populations in high to very high-risk zones need timely attention of the local authorities to avert any unwanted happenings.

Spatial and temporal dynamics of soil organic carbon stock and carbon sequestration affected by major land-use conversions in Northwestern highlands of Ethiopia

Soil organic carbon (SOC) is the major component of the terrestrial carbon (C) budget, a key indicator of environmental sustainability. So, estimating SOC stock and soil carbon (C) sequestration dynamics is important for evidence-based and carbon-conscious decisions. Quantification of SOC stock and soil C sequestration affected by land-use changes (LUCs) have received much attention in addressing food and climate security. This study aims to estimate the dynamics of SOC stock, soil C sequestration and associated soil parameters affected by major LUCs from 2012 to 2021 in Awi highlands of Amhara Regional State of Ethiopia. The study area has experienced dramatic LUC, particularly plantation and growing of Acacia decurrens (J.C. Wendl.) tree followed by recurrent deforestation and then cropping and back to the plantation. The study quantified spatial and temporal dynamics of SOC stock, soil C sequestration and associated changes affected by the LUCs. A total of 22 topsoil (0–20 cm) legacy data was obtained from the Ethiopian Soil Information System (EthiSIS) database of 2012. The same number of samples were collected at the same locations in 2021 by using the same sampling procedure as that of 2012. In addition, the same number of core samples were collected in 2021 for bulk density analysis. To estimate the unmeasured bulk density of legacy data, we applied a pedotransfer function. We used empirical equations and basic statistics to assess changes in SOC stock and C sequestration rate between the two periods. Statistically significant variation (P < 0.01) in SOC stock and C sequestration was observed between the two periods. LUC from acacia plantation to croplands caused a decline of SOC stock by −30.16%, and it also caused the decline of total nitrogen stock, available phosphorus, cation exchange capacity (CEC). However, the reverse LUC caused an increase in SOC by 27.74% and the abovementioned soil parameters. LUC from plantation forest to cropland caused emission of 8.3 tons of CO2 year−1. Generally, overall LUCs caused the net negative change in SOC stock by (−2.42 %) and associated soil parameters in the last ten years. Our study provides evidence that overall LUCs in the current study site caused a decline in SOC stock, along with associated soil parameters with carbon emitted to the atmosphere. Hence, sustainable land-use management options which can offset losses in SOC stock should be implemented soon.

The Effect of Covid-19 on Unemployment and Price Changes in Ethiopia: Evidence from Woldia Town “Does The Downward Sloping Philips Curve Hold True at Micro Level”

The massive spread of corona creates pressure on the general systems of the world countries. As stated in some studies corona virus affect every institution and individuals of the world in many aspects. Specifically it results in high unemployment, low level of production and significance rise in the nominal price of commodities. This study tries to explain the change in those economic variables to analyze the effect of Covid-19 on the living standard of households in Woldia town, Amhara regional state of Ethiopia using a data obtained from the north wollo zone planning commission which had been collected from sampled individuals monthly. Since the issue is so recent and absence of many conducted researches on this area, this article have no specific chapter for review of literature and gives more focus for data analysis part. Then descriptive analysis indicates the presence of valuable rise in unemployment and average price levels simultaneously and the OLS regression result disproved the applicability of Philips curve for the study area under the influence of COVID-19.

Behavioral and Sociodemographic Determinants of Hypertension and Its Burden among Bank Employees in Metropolitan Cities of Amhara Regional State, Ethiopia.

Background Hypertension is the leading cause of cardiovascular disease and premature death worldwide. Bank workers are at higher risk of hypertension because of their work sedentary characteristics. However, little is known about the prevalence and determinants of hypertension among this group of population. Therefore, this study aimed to assess the prevalence and associated factors of hypertension among bank employees in metropolitan cities in Amhara Regional State of Ethiopia. Method An institution-based cross-sectional study was conducted among 368 bank employees. A simple random sampling technique was used to select participants. A pretested self-administered questionnaire and biophysical measurements were employed to collect the data. Descriptive statistics and logistic regression analyses were done to summarize the data and identify factors associated with hypertension, respectively. Result The overall prevalence of hypertension among bank employees was 52.4% (95% CI: 47.2, 57.7). Increased age (AOR = 1.1, 95% CI: 1.03, 1.11), male sex (AOR = 2.5, 95% CI: 1.2, 5.1), overweight (AOR = 2.7, 95% CI: 1.5, 5.2), obesity (AOR = 5.6, 95% CI: 2.0, 11.3), moderate/high physical activity (AOR = 0.36, 95% CI: 0.2, 0.62), daily fruit intake (AOR = 0.1, 95% CI: 0.04, 0.3), stressful life event experience (AOR = 1.8, 95% CI: 1.01, 3.4), family history of hypertension (AOR = 2.8, 95% CI: 1.5, 5.4), and poor knowledge of CVDs (AOR = 2.4, 95% CI: 1.2, 4.8) were significantly associated with hypertension. Conclusion The prevalence of hypertension among bank workers was very high. Increased age, male sex, overweight and obesity, daily fruit intake, moderate/high physical activity, the experience of stressful events, familial history of hypertension, and poor CVDs knowledge were associated with hypertension. Thus, raising awareness about cardiovascular disorders and behavior change interventions that enhance bank workers' engagement in physical exercise, screening behavior, and a healthy diet is urgently required for this group of population.

Growth Assessment of Tree Species Growing in the Amhara Region in Ethiopia

ABSTRACT Ethiopian mixed forests have multipurpose benefits and services. However, there is a gap of information in the entire Ethiopian highlands on forest growth needed for implementation of sustainable forest management and provision of ecosystem services. Therefore, main aim of this study was to identify main factors deriving tree growth in forest and woodland in Amhara Regional State of Ethiopia and to provide an individual tree basal area increment (BAI) model based on increment cores. The data came from 170 sampling plots in study area and cover 51 tree species. For each tree species, diameter at breast height (DBH), height, increment core measurement, tree location, and distance from subject tree measurements were recorded. Because of large number of trees species, it is difficult to develop growth functions for each individual tree species. Thus, classification of species groups provided a framework to organize information that differs between vegetation types. Our classification resulted in three groups. For each tree species group, an individual tree BAI model was calibrated. The tree species group of BAI differs by DBH class. The response to BAI depends on competitive condition of a tree. This growth model can be used to predict tree growth for Ethiopian mixed-species forests.
