Background Recent studies have shown an increase in open defecation and slippage of open defecation-free certified villages in Ethiopia, despite significant progress the country made on sanitation programs. Hence, realizing of existing facts, this study was conducted aiming at a critical review of available literature and to provide consolidated data showing the level of slippage and its associated factors in Ethiopia. Methods Systematic literature searches were performed from four international databases. The search involved articles published from December 1, 2013, up to June 4, 2019. The Cochran’s Q and I2 test statistics were used to check heterogeneity among the studies. To negotiate heterogeneity from qualitative data, we used a mixed-method approach. The researchers also conducted a publication bias assessment and sensitivity analysis. A random effect meta-analysis was employed to determine the pooled estimates of open defecation free slippage rate with a 95% confidence interval (CI). The data analysis was performed using the CMA V.3 software program. Result After screening 1382 studies, 12 studies were finally included in this systematic review. The estimated pooled rate of open defecation-free slippage in Ethiopia was 15.9% (95% CI 12.9–19.4%). The main contributing factors for open defecation-free slippage were lack of technical support, financial constraints, low-quality building materials, improper program implementation, and lack of sanitation marketing. Conclusion It was estimated that 1 out of 6 Ethiopian households engaged in open defecation after they have certified open defecation-free status, implying the low possibility of achieving sustainable development goals of 2030, which aims to ensure sanitation for all. Therefore, the government of Ethiopia and donors should better give special attention to the following options: (1) awareness for open defecation-free slippage, (2) launch a post-open defecation-free program, and (3) encourage research on pro-poor sustainable sanitation technologies.

Abstract:Up to the present day, wood has been used to supply the needs for cooking in rural Africa. Due to the ongoing deforestation, households need to change to other energy sources. To cover this need, a large amount of people are using residues from agriculture (straw, manure) instead. However, both straw and manure also have a function in agriculture for soil improvement. Using all the straw and manure will seriously affect the food production. In this paper we first determine the amount of energy that households need for cooking (about 7 GJ per year). Then we estimate the amount of residues that can be obtained from the agricultural system and the amount of energy for cooking that can be derived from this amount when different conversion techniques are used. The amount of residues needed is strongly affected by the technology used. The traditional three stone fires require at least two times as much resource than the more advanced technologies. Up to 4 ha of land or 15 cows are needed to provide enough straw and manure to cook on the traditional three stone fires. When more efficient techniques are used (briquetting, biogas) this can be reduced to 2 ha and six cows. Due to large variation in resource availability between households, about 80% of the households own less than 2 ha and 70% holds less than four cows. This means that even when modern, energy efficient techniques are used the largest share of the population is not able to generate enough energy for cooking from their own land and/or cattle. Most rural households in Sub-Saharan Africa may share similar resource holding characteristics for which the results from the current findings on Ethiopia can be relevant.

Background Governments have imposed physical and social distancing measures together with hand hygiene to contain COVID-19. However, maintaining the recommended social distancing less likely applicable in developing countries where the majority of the people depend on daily income. Countries like Ethiopia imposed universal use of face masks as an additional measure. Aim This study aims to review and present the advantage and challenges of imposing universal use of face masks in the community and to forward possible recommendations. Methods The study was synthesized using a narrative literature review approach involving COVID-19 databases, published literature on COVID-19, and relevant news. Results The first confirmed case of COVID-19 in Ethiopia was reported on March 13, 2020. Consequently, the government has taken swift actions including social distancing and strict hygienic measures to contain its transmission. However, new cases have started to increase with local transmission. Hence, the country imposed additional measures including universal use of face masks at public places. The universal use of masks requires a sufficient supply of masks with affordable costs. Moreover, awareness of the proper use of face masks and its disposal is another challenge affecting its effectiveness against corona virus infection. Conclusion Universal use of face masks can contribute to the containment of the virus in the community if adequately available and properly used and managed after use. Encouraging local production with clear guidance, demonstration, and awareness creation helps to improve the accessibility and effectiveness of face masks particularly among the vulnerable population.

Most households in rural developing countries depend on firewood from public forests or agricultural bio-wastes for cooking. Public forests, though, are declining due to an increasing population and inefficient use of wood. Use of agricultural wastes on the other hand involves loss of soil nutrients since these resources are used as a substitute for inorganic fertilizers. Biogas energy can be an alternative in providing clean energy for cooking as well as improving soil fertility with the slurry. However, the labor spent on producing biogas can limit its use as a source of energy and fertilizers. Therefore, this study aims to determine the labor requirement of different mono and co-digestion biogas energy systems. The assessment is made by using simple models involving different schemes of resources collection and transportation based on reported relevant literature. The analysis shows that biogas production can be labor intensive when transportation of feedstock, water, and slurry is involved. Transporting these resources over a one kilometer (km) distance requires about ten times the amount of time spent on firewood collection and transportation. The largest part of the time for biogas production activities is spent on water collection and transportation. Low labor biogas production is possible only if all the resources are available nearby (not transported). One of the advantages of the biogas energy system is to use the slurry for soil enrichment. However, this can only be realized when the slurry is converted to compost or directly applied on nearby lands. In general, biogas production involving resources (feedstock, water and slurry) transportation is not a viable alternative to save the time spent on the traditional use of firewood. However, a community biogas system involving resource system integration is an option to provide clean energy with acceptable labor requirements of production.

Background: Most households in rural developing countries do not have access to modern energy supply. Household level biogas energy was considered as an option but failed due to lack of sufficient resources for its installation and operation. A community energy system can be an option, but most studies focused on off-grid electricity. This energy system cannot be a realistic option particularly for cooking demand. An efficient and suitable system matching local resources and demand expectation needs to be developed which this study focuses on assessing. Biogas and solar energy technologies are viable to establish such kind of a system since they can be converted to different forms of energy. Therefore, this study aims to determine efficient biogas and solar energy production and utilization options for small scale village energy application in rural Ethiopia. Methods: The efficiencies of the production and utilization options are determined based on the system configurations involving resource, conversion, and utilization combination models. We used local resources, data, and relevant literature information for the system analysis. Results: The analysis shows that most energy is needed in the form of heat for cooking and a smaller part in the form of electricity (about 10%). The community waste stream converted to biogas will be enough for cooking, but not enough biogas is left to produce enough electricity. Co-digesting altogether provides biogas that can meet only about 75% of the electricity demand. Concentrated solar cookers can be an alternative for cooking in areas where installation of biogas is not possible. About 2-m 2 size solar concentrator is sufficient to meet each household's cooking energy demand. The lighting and appliance energy demand can be met with photovoltaic (PV) energy produced with reasonably sized panels. However, the use of electrical energy for cooking produced with PV cannot be an economic option with the available technologies. Conclusions: The community energy system involving anaerobic co-digestion (biogas) and/or solar energy technologies is viable to meet the demand when efficient production and conversion is made based on specific local resource supply and demand.

Background Community attitude towards mental health problems and help-seeking behavior plays a major role in designing effective community based mental health interventions. This study aimed to assess the attitude, help-seeking behavior, and associated factors of the Jimma zone community towards mental health and mental health problems. Methods A community-based cross-sectional study design was employed. A respondent from each of the 423 systematically selected households was interviewed using a pretested, structured, and interviewer-administered questionnaire. Accordingly, a community’s attitude towards mental health problems was measured by the adapted version of the “Community Attitude towards Mentally Ill questionnaire (CAMI)” and help-seeking behavior was measured by a general help-seeking questionnaire. Data were entered into Epi-data version 3.1 and exported to SPSS version 23.0 for analysis. Bivariate and multivariate logistic regression analysis was done to determine the independent predictors of the outcome variable. Results Among the total 420 study participants (197,46.9%) of them had an overall unfavorable attitude towards mental illness. The majority (153,36.4%) of the study participants agreed on avoidance of anyone who has mental health problems and (150,35.7%) participants described marrying a person with a mental health problem or recovered from the problem is foolishness. Moreover, regression analysis showed family monthly income (AOR = 0.24, 95%CI:0.06–0.91) and occupational status (AOR = 0.57, 95%CI:0.34–0.96) were found to be the predictors of community attitude towards mental health problems. The study finding also revealed a significant number of the respondents preferred non- medical treatment approaches. Conclusion Almost half of the respondents had an unfavorable attitude towards mental health problems and the traditional and religious help-seeking intention was high. This suggests the need for designing effective community based mental health interventions to improve the general public attitude and help-seeking behavior towards mental health problems.
