Traditional gold mining in the highlands of Ethiopia: Its effect on soil loss and possible reclamation measures

Traditional gold mining (TGM) is among the off-farm income sources of smallholder communities in the highlands of Ethiopia. However, information on their impact on land degradation, taking soil loss as a key indicator, was scant. Hence, this study aimed at i) analyzing local communities’ attitudes toward TGM practice, ii) TGM impact on soil loss, and iii) possible restoration measures for the degraded gold-mined landscapes. For the evaluation of community perceptions, 96 beneficiaries were selected from three gold mining sites following stratified random sampling techniques. Soil loss measurement was done through measurement of i) the mass of soil excavated and transported to the river (TR) from 96 individuals and ii) soil volume excavated in 45 excavated soil pits (EP). Descriptive statistics and one-way ANOVA were used to analyze soil loss data, while community perception was analyzed qualitatively. The survey results indicated that the average soil loss from TR and EP were 6,075.97±8.9 t ha-1 yr-1 and 32,549.99±753.68 t ha-1, respectively. The magnitude of soil loss also showed a significant (p<0.001) difference among the three sites. Due to a lack of awareness and hiding the reality, most of the gold miners believe that TGM practice has no negative impact on the soil resource, and no post-mined reclamation strategy is implemented. It can be concluded that the existing TGM practices are not done in an environmentally friendly approach and result in adverse soil loss. Hence, stabilizing the topography of the mined sites via backfilling of mined pits and topsoil conservation and amendment measures can be suggested

Water balance components of the potential agricultural grabens along the Rift Valley in northern Ethiopia

Region: Ethiopia's Rift Valley. Focus: matching agricultural water demand and supply is a growing policy challenge in drylands. We investigated the water balance components in Raya (3507 km(2)) and Ashenge (80.5 km(2)) grabens. The rainfall depth, river discharge, abstraction, climate and soil data (2015-2017) were used to address the research question. New hydrological insights: the average annual rainfall of the graben's escarpment and its bottom was 806 +/- 162 and 508 +/- 110 mm, respectively. Heavy rains produce floods up to 732 m(3) s(-1) in the rivers that flow into the Raya graben. Moreover, greater runoff and river discharges volumes were recorded at the graben escarpments than at the graben bottom outlets (p < 0.001) due to the greater contributing area (p < 0.001, R-2 = 0.98) and headwater elevation (p < 0.001, R-2 = 0.98). About 24% of the water entering both graben bottoms comes from the runoff from the adjacent slopes, and about 40% of the runoff reaching the Raya graben bottom flowed out at the outlet. About 76% and 77.5% of the annual rainfall was lost through evapotranspiration from the Raya and Ashenge grabens, respectively. So about 16% and 33% of the average annual inflows infiltrated into the sediments in the Raya and Ashenge grabens, respectively. These insights provided by this study into the water balance in grabens along the Rift Valley can be used to help achieve sustainable agricultural development

Experience of Research Undertaking among Women Academia at Addis Ababa University: a Qualitative Study

AbstractBackground: As a pioneer University in the Country, Addis Ababa University engages itself in collaborative and local research undertakings along with teaching, community engagements and technology transfer. Despite its long engagement in research, the participation of women academia in research is limited as manifested by their low research productivity in terms of publication in peer-reviewed scientific journals. However, the reasons for their low research participation are less known and needs further exploration. Objective: To explore the experience of research undertakings among women academia at Addis Ababa University. Method: We conducted an exploratory qualitative study using a phenomenological approach among women academia. Eight women who have been working in the University with a rank of a lecturer having at least two years participated in in-depth interviews. We used NVivo10 software to code and categorize the transcripts. Result: Our study revealed that only a few senior informants with more than 10 years of stay at the University had a better experience in applying for national and international research grants. Although all the participants said they had ever undertaken research, their publication track in peer-reviewed journals is limited. Social and economic factors, lack of networking, low salary and family responsibility, limited internet and library access, and lack of research skill among young faculty were raised as impediments to undertake research. Conclusion: This study has indicated that women in academia had limited research engagement in terms of grant application and publication in peer reviewed scientific journals. Balancing work and family life, low salary, lack of access to common University facilities were some of the challenges. While structural change ensures gender equality at a long time, addressing the gender gap in research is the responsibility of AAU. [Ethiop. J.

Female Academic Career Development and Administrative Positions at Addis Ababa University: a Mixed-Method Study

AbstractBackground: In Ethiopia, the number of female in academia in general and in administrative positions and higher university ranks in specific is very small as compared to men. A slight change has been seen in recent years, where a few women have come to male-dominated administrative positions as university presidents, vice presidents, deans and directors with still insignificant increase in the number of full professors. Objective: This study assessed female faculty member's career development and involvement in administrative positions and explored challenges. Method: We used a sequential mixed-method study starting with a cross-sectional quantitative study among 888 faculty members. The quantitate data were analysed using descriptive statistics and regression models to identify independent predictors of administrative involvement using SPSS version 25 software. An exploratory qualitative study was done among eight purposively selected female faculty. NVivo10 data management software was used to code and categorize the transcripts. Result: We found that male faculty members were more likely to involve in administrative positions than their female counterparts [AOR (95%CI) 1.6(1.1, 2.4)]. Those who were provided housing facility by AAU [AOR (95%CI) 2.29 (1.61, 3.23)] and assistant professors and above [AOR (95%CI) 1.495 (1.01, 2.220)] were more likely to involve in an administrative position than their counterparts. The qualitative findings indicated that the low salary faculty earns, lack of networks and family responsibility have deterred females from taking administrative positions. Conclusion: Female faculty involvement in the university administrative position and career development is very low. Both structural and personal factors such as gender roles affected their professional enhancement in academic ranks and hence positions. Creating a conducive platform for female faculty development is recommended to increase their involvement in administrative positions. [Ethiop. J.

Gender Difference in Research Productivity and its Associated factors in Addis Ababa University: a Cross-Sectional study

AbstractBackground: Gender equity movements have increased the number of women going to higher institutions. However, the number of women participating in research is limited in creating a critical mass. Objective: To assess the gender gap in research and its associated factors determinants among faculty at Addis Ababa University. Method: We conducted a cross-sectional study from October 2018 to March 2019 using a structured self-administered questionnaire. University faculty who was lecturers and above level who served the University for more than a year were invited to participate in the study. Faculty were approached by data collection facilitators with graduate degrees and the secretory of the respective departments. We used descriptive and multivariate statistical methods to analyse the data. Result: Of the 888 study participants, 161 (18.1%) females faculty participated in the study. It was found that three hundred ninety-seven male academics (54.6%) and 50 female academics (31.1%) had ever published articles in peer-reviewed journals (p&lt;0.001). Male faculty were more likely to publish in peer-reviewed journals than their female counterparts [AOR and (95% CI) [2.55 (1.68, 3.86)]. Faculty with a rank of assistant professors and above [AOR (95% CI) 3.47(2.31, 5.21)], those who have a Ph.D. as highest degree [AOR (95% CI) 2.98 (2.11, 4.19) and those who have affiliation with other institutions [AOR (95% CI) 2.59 (1.98, 3.56)], were more likely to publish in peer-reviewed journals than their counterparts. Conclusion: Female faculty were less likely to be involved in research than men counterparts. The University needs to narrow the gender gap in research by designing and implementing an appropriate intervention strategy. [Ethiop. J.

Global, regional, and national burden of traumatic brain injury and spinal cord injury, 1990-2016: a systematic analysis for the Global Burden of Disease Study 2016.

Traumatic brain injury (TBI) and spinal cord injury (SCI) are increasingly recognised as global health priorities in view of the preventability of most injuries and the complex and expensive medical care they necessitate. We aimed to measure the incidence, prevalence, and years of life lived with disability (YLDs) for TBI and SCI from all causes of injury in every country, to describe how these measures have changed between 1990 and 2016, and to estimate the proportion of TBI and SCI cases caused by different types of injury. METHODS: We used results from the Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study 2016 to measure the global, regional, and national burden of TBI and SCI by age and sex. We measured the incidence and prevalence of all causes of injury requiring medical care in inpatient and outpatient records, literature studies, and survey data. By use of clinical record data, we estimated the proportion of each cause of injury that required medical care that would result in TBI or SCI being considered as the nature of injury. We used literature studies to establish standardised mortality ratios and applied differential equations to convert incidence to prevalence of long-term disability. Finally, we applied GBD disability weights to calculate YLDs. We used a Bayesian meta-regression tool for epidemiological modelling, used cause-specific mortality rates for non-fatal estimation, and adjusted our results for disability experienced with comorbid conditions. We also analysed results on the basis of the Socio-demographic Index, a compound measure of income per capita, education, and fertility. FINDINGS: In 2016, there were 27·08 million (95% uncertainty interval [UI] 24·30-30·30 million) new cases of TBI and 0·93 million (0·78-1·16 million) new cases of SCI, with age-standardised incidence rates of 369 (331-412) per 100 000 population for TBI and 13 (11-16) per 100 000 for SCI. In 2016, the number of prevalent cases of TBI was 55·50 million (53·40-57·62 million) and of SCI was 27·04 million (24·98-30·15 million). From 1990 to 2016, the age-standardised prevalence of TBI increased by 8·4% (95% UI 7·7 to 9·2), whereas that of SCI did not change significantly (-0·2% [-2·1 to 2·7]). Age-standardised incidence rates increased by 3·6% (1·8 to 5·5) for TBI, but did not change significantly for SCI (-3·6% [-7·4 to 4·0]). TBI caused 8·1 million (95% UI 6·0-10·4 million) YLDs and SCI caused 9·5 million (6·7-12·4 million) YLDs in 2016, corresponding to age-standardised rates of 111 (82-141) per 100 000 for TBI and 130 (90-170) per 100 000 for SCI. Falls and road injuries were the leading causes of new cases of TBI and SCI in most regions. INTERPRETATION: TBI and SCI constitute a considerable portion of the global injury burden and are caused primarily by falls and road injuries. The increase in incidence of TBI over time might continue in view of increases in population density, population ageing, and increasing use of motor vehicles, motorcycles, and bicycles. The number of individuals living with SCI is expected to increase in view of population growth, which is concerning because of the specialised care that people with SCI can require. Our study was limited by data sparsity in some regions, and it will be important to invest greater resources in collection of data for TBI and SCI to improve the accuracy of future assessments
