A Farmer-based fruit seedling supply system in Dale Pilot Learning Woreda (PLW): experiences from IPMS

Dale Woreda is well known for its avocado (Persia americana) and to a lesser extent mango (Mangifera indica) production. These fruit trees are planted along with coffee (Coffee arabica), enset (Enset ventricosum) and other crops. They are important sources of income and food, playing a considerable role in the livelihood of thousands of smallholder farmers of Dale. However, the varieties found in the area have large canopies that reduce land availability for other crops. They are also tall (10-15 m) thus harvesting becomes a challenge, particularly for women. Market prices for these varieties are low and during collection, there is considerable fruit loss when they fall, causing cracks and bruises and hence their rejection. The trees also take 7- 10 years to bear fruit and farmers mention that the land can be used more productively and therefore want to replace fruit trees with other more profitable crops. The diagnostic survey carried out by Improving Productivity and Marketing Success (IPMS) of Ethiopian farmers’ project identified some of the above production constraints as the major area of intervention. Further study was conducted by the International Centre for Research on Agro Forestry (ICRAF) which confirmed the above problems and suggested introduction of improved variety through grafting as one of the best solution to improve the quality of seed, reduce size and height as well as improve productivity and marketability of these varieties. Taking the experience of Dale for coffee seedling production where farmer’s nurseries have taken over 95% of seedling production, the Dale partners decided to use farmers’ nurseries as the base to start production of grafted seedlings. Using participatory extension methods with the help of various partners, the number of private nursery operators increased from the initial six (3 females) to 20 (7 female) in 2009. The number of seedlings produced has now reached 12,000 annually and this can be easily expanded since scions can now be obtained from mother trees established earlier in each of the nursery sites. Currently, seedlings are sold at around Birr 15/seedling to neighboring farmers, some on credit provided by the nursery operators. Linkages with the Productive Safety Net program are made to facilitate the scaling out of the sale of seedlings to emerging commercial farmers. Nursery operators earned between Birr 4,000–7,000 per year from these operations. Further skills development can still be made to improve survival rates of grafted seedlings. Attention will also need to be paid to the marketing of these improved varieties as well as the development of a responsive support system providing fresh knowledge, building capacity and new technologies

Prevalence and associated risk factors of ophthalmic problems of working donkeys (Equus asinus) in Mekelle, Northern Ethiopia

A cross-sectional study was conducted from December 2017 to March 2018 aimed at determining the prevalence and associated risk factors of ophthalmic problems of working donkeys in Mekelle, Northern Ethiopia. Study animals were selected by random sampling method to obtain the primary data in the form of direct physical examination and history was obtained from the owner of each examined donkey at the same time. Descriptive statistics was employed to summarize the data and uni-variant logistic regression was used to quantify the degree of association between ophthalmic problems and identified risk factors. Accordingly, out of the total 384 examined, 181 were found to be positive for ophthalmic problems with an overall prevalence of 47.14%. In this study, a statistical significant difference (P<0.05) were found among age groups and sexes. Female donkeys (63.01%) were 2.08 (OR=2.08; 95% CI: 1.105, 3.942) times more likely to have ophthalmic problems compared to male donkeys (44.97%). Donkeys with age category of >10 years (62.07%) and 6-10 years (49.6%) were 3.34 (OR=3.34; 95% CI: 2.002, 5.578) and 2.01 (OR=2.01; 95% CI: 1.225, 3.296) times more likely to have ophthalmic problems as compared to the age group of <6 years (32.87%) old, respectively. Ophthalmic problems are relatively higher in the right eye (41.44%) than the left (39.78%). Higher percentages were observed due to conjuctival defect (29.28%), followed by general lesion of eyelid (26.52%) and corneal defects (13.26%). The possible causes were diseases (62.98%) and mechanical damages (37.02%). In conclusion, the prevalence of ophthalmic problems in the study area is very high. Therefore, better management practices and awareness creation among donkey owners is highly recommended. Keywords: Mekelle; Ophthalmic problems; Prevalence; Risk Factors; Working Donkey

Governments' policy response to drought in Eswatini and Lesotho : a systematic review of the characteristics, comprehensiveness, and quality of existing policies to improve community resilience to drought hazards

The southern African kingdoms of Eswatini and Lesotho experience recurrent drought-induced disasters. Policies have been enacted, but no attempt has been made to synthesise the effects on disaster resilience. This review analyses the characteristics, quality, and comprehensiveness of drought-resilience policies in Eswatini and Lesotho. We have systematically reviewed public policies that shape responses to disaster resilience published between 1 January 1980 and 30 June 2019. A combination of keywords was used to search electronic bibliographic databases, multidisciplinary databases, key organisational websites, and the first 20 pages of Google for policies that addressed disaster and/or drought resilience. Identified documents were downloaded into an EndNote database and screened for eligibility using predetermined criteria. The logic of events framework was used for quality assessment, and a metaethnographic approach was applied for data synthesis. Three broad categories of characteristics, thematic outcomes and quality, and comprehensiveness of policy documents emerged and are presented. Policy responses contributing to disaster resilience were found in n = 32 out of 13,700 documents. Three (n = 3/32) policies were statutory, and the rest were nonstatutory. Eleven (n = 11/32) were assessed to be of high quality. Policy responses relating to drought resilience focused on reducing vulnerability to recurrent disasters; promoting drought and climate change adaptation; improving agriculture and food security; safeguarding cultural heritage; and preventing gender inequality and gender-based violence as well as improving disaster governance. However, the construct of drought resilience was not strongly articulated as a major policy goal across policy documents. There is an urgent need to promote better understanding of drought resilience in order to motivate policymakers to steer away from reactive interventions and position resilience as a major national policy goal in both countries to expedite inclusive growth and safeguard development gains and the health and wellbeing of the majority of their populations who are rural-based populations

Performance Appraisal Fundamentals, Practices and Challenges in Public Sector: Case of Adigrat Town, Ethiopia

PURPOSE & AIM: In Ethiopian Context, the modern Performance Appraisal practices and its implementation are still in its nascent stage, and there exists a gap in understanding the mechanism of performance appraisal processes in the case of Ethiopia’s public sector organizations, which employs a significant proportion of the working population

Unexplained chronic liver disease in Ethiopia: a cross-sectional study

BACKGROUND: Hepatitis B virus (HBV) infection is assumed to be the major cause of chronic liver disease (CLD) in sub-Saharan Africa. The contribution of other aetiological causes of CLD is less well documented and hence opportunities to modulate other potential risk factors are being lost. The aims of this study were to explore the aetiological spectrum of CLD in eastern Ethiopia and to identify plausible underlying risk factors for its development. METHODS: A cross-sectional study was undertaken between April 2015 and April 2016 in two public hospitals in Harar, eastern Ethiopia. The study population comprised of consenting adults with clinical and radiological evidence of chronic liver disease. The baseline evaluation included: (i) a semi-structured interview designed to obtain information about the ingestion of alcohol, herbal medicines and local recreational drugs such as khat (Catha edulis); (ii) clinical examination; (iii) extensive laboratory testing; and, (iv) abdominal ultrasonography. RESULTS: One-hundred-and-fifty patients with CLD (men 72.0%; median age 30 [interquartile range 25-40] years) were included. CLD was attributed to chronic HBV infection in 55 (36.7%) individuals; other aetiological agents were identified in a further 12 (8.0%). No aetiological factors were identified in the remaining 83 (55.3%) patients. The overall prevalence of daily khat use was 78.0%, while alcohol abuse, defined as > 20 g/day in women and > 30 g/day in men, was rare (2.0%). Histological features of toxic liver injury were observed in a subset of patients with unexplained liver injury who underwent liver biopsy. CONCLUSION: The aetiology of CLD in eastern Ethiopia is largely unexplained. The widespread use of khat in the region, together with histopathological findings indicating toxic liver injury, suggests an association which warrants further investigation

Development of a health-related website for parents of children receiving hematopoietic stem cell transplant: HSCT-CHESS

Parents of pediatric hematopoietic stem cell transplant (HSCT) play a pivotal role in the care of their child during and after transplant. In addition to the child’s comforter, parents also serve as care coordinators and conduits of communication between various health care providers, family and community members. The stress on the parent and family is enormous during this process, which for many is compounded by geographic dislocation to accompany their child during the rigorous treatment and recovery process. For many parents, their own recovery spans months to years

Scalable Synthesis of Micron Size Crystals of CH3NH3PbI3 at Room Temperature in Acetonitrile via Rapid Reactive Crystallization

From application point of view, scalable, facile and rapid synthesis method for mass production of a homogeneous and phase pure CH3NH3PbI3 micron size crystal at the industry level is still highly required, although it has been claimed that the CH3NH3PbI3 crystals can be prepared by solution-annealing the precursors at elevated temperature or prolonged reaction time. Herein, polycrystalline CH3NH3PbI3 micron size crystals can be prepared by reactive crystallization of PbI2 and CH3NH3I in a stoichiometric ratio at room temperature. TXM (Transmission X-ray Microscopy), optical microscope, TEM and TEM-EDX analysis were used to confirm the nature of the CH3NH3PbI3 product. Moreover, Ostwald ripening of iodide ion into PbI2 is proposed as the key step to form 3D PbI3−, followed by the intercalation of CH3NH3+ for this reactive crystallization. Interestingly, this result suggests that industry level mass production of micron CH3NH3PbI3 crystals is possible with this novel synthesis method

Maintaining behaviour change: innovations in demand-side sanitation and hygiene interventions

This paper explores innovations in demand-side sanitation and hygiene intervention design and implementation. These innovations build on approaches employed by Community-Led Total Sanitation and Hygiene (CLTSH) programming to sustain improved WASH behaviours. Through an iterative process, our team conducted formative activities in Amhara, Ethiopia to: 1) generate information regarding stakeholders’ experiences with the government’s Health Extension Package (HEP) and previous CLTSH programming, and 2) explore options for intervention design and delivery. Our results suggest in some cases, community members were willing to engage in demand-side sanitation and hygiene programming after having negative experiences with ineffectual CLTSH triggering. Health Extension Workers (HEWs) indicated that high demand is placed on them to deliver the 16-component HEP. We conclude that what is needed are demand-side approaches that: 1) engage more community-level change agents, 2) include plans and resources to provide community actors with supportive supervision and on-the-job-training, and 3) focus on behavioural maintenance

Interpreting ambiguous ‘trace’ results in Schistosoma mansoni CCA Tests: Estimating sensitivity and specificity of ambiguous results with no gold standard

Background The development of new diagnostics is an important tool in the fight against disease. Latent Class Analysis (LCA) is used to estimate the sensitivity and specificity of tests in the absence of a gold standard. The main field diagnostic for Schistosoma mansoni infection, Kato-Katz (KK), is not very sensitive at low infection intensities. A point-of-care circulating cathodic antigen (CCA) test has been shown to be more sensitive than KK. However, CCA can return an ambiguous ‘trace’ result between ‘positive’ and ‘negative’, and much debate has focused on interpretation of traces results. Methodology/Principle findings We show how LCA can be extended to include ambiguous trace results and analyse S. mansoni studies from both Côte d’Ivoire (CdI) and Uganda. We compare the diagnostic performance of KK and CCA and the observed results by each test to the estimated infection prevalence in the population. Prevalence by KK was higher in CdI (13.4%) than in Uganda (6.1%), but prevalence by CCA was similar between countries, both when trace was assumed to be negative (CCAtn: 11.7% in CdI and 9.7% in Uganda) and positive (CCAtp: 20.1% in CdI and 22.5% in Uganda). The estimated sensitivity of CCA was more consistent between countries than the estimated sensitivity of KK, and estimated infection prevalence did not significantly differ between CdI (20.5%) and Uganda (19.1%). The prevalence by CCA with trace as positive did not differ significantly from estimates of infection prevalence in either country, whereas both KK and CCA with trace as negative significantly underestimated infection prevalence in both countries. Conclusions Incorporation of ambiguous results into an LCA enables the effect of different treatment thresholds to be directly assessed and is applicable in many fields. Our results showed that CCA with trace as positive most accurately estimated infection prevalence

Controls on timescales of soil organic carbon persistence across sub-Saharan Africa

Given the importance of soil for the global carbon cycle, it is essential to understand not only how much carbon soil stores but also how long this carbon persists. Previous studies have shown that the amount and age of soil carbon are strongly affected by the interaction of climate, vegetation, and mineralogy. However, these findings are primarily based on studies from temperate regions and from fine-scale studies, leaving large knowledge gaps for soils from understudied regions such as sub-Saharan Africa. In addition, there is a lack of data to validate modeled soil C dynamics at broad scales. Here, we present insights into organic carbon cycling, based on a new broad-scale radiocarbon and mineral dataset for sub-Saharan Africa. We found that in moderately weathered soils in seasonal climate zones with poorly crystalline and reactive clay minerals, organic carbon persists longer on average (topsoil: 201 ± 130 years; subsoil: 645 ± 385 years) than in highly weathered soils in humid regions (topsoil: 140 ± 46 years; subsoil: 454 ± 247 years) with less reactive minerals. Soils in arid climate zones (topsoil: 396 ± 339 years; subsoil: 963 ± 669 years) store organic carbon for periods more similar to those in seasonal climate zones, likely reflecting climatic constraints on weathering, carbon inputs and microbial decomposition. These insights into the timescales of organic carbon persistence in soils of sub-Saharan Africa suggest that a process-oriented grouping of soils based on pedo-climatic conditions may be useful to improve predictions of soil responses to climate change at broader scales
