GIS-Based multi-criteria land suitability mapping for scaling faba bean varieties in Ethiopia.

Successful scaling of agricultural technology requires a spatial explicit framework for targeting the right variety at the right place. This entails a multi-criteria evaluation (MCE) approach, using a set of determining factors to delineate the scaling domains for faba bean ( Vicia faba L.) varieties in and identify potentially suitable land area in a specific region, and zone in Ethiopia. Meeting this challenge will require a solid spatial framework. Land suitability analysis is an evaluation and spatial decision making, involving several determining factors. The factors considered in this analysis include key biophysical parameters such as climate, topography, soil types and properties. The analysis was also focused on improved faba bean varieties viz., Dagm, Dosha, Gabelcho, Gora, Hachalu, Moti and Walki. The environmental factors\u2019 layers of a specific crop pixel values were classified and given a weight, and then compared among themselves for further ranking to account for their relative importance to delineate variety specific extrapolation domains. The geo-statistical analysis was carried out to estimate the extent of the scalable areas. The classification showed that, it was highly suitable for varieties 0.02 million hectares for Dosha; 0.19 for Gabelcho; 0.11 for Gora; 0.33 for Moti; 0.05 for Dagm; 0.14 for Hachalu; and 0.26 million hectares for Walki. Moderately suitable areas for these varieties covered 5.0, 9.4, 7.2, 15.3, 4.6, 8.8, and 7.5 million hectares, respectively across the country. The largest proportion for all varieties was moderately suitable; while the share of slightly suitable was very low, although there was quite variability within each of the faba bean variety in terms of its agro-ecology adaptation to the target environments. Such biophysical spatial frameworks become essential entry points for introducing variety specific product profiles and this can be further enhanced by incorporating socio-economic attributes accounting for return of the investment in targeting the technology.La mise \ue0 l\u2019\ue9chelle r\ue9ussie de la technologie agricole n\ue9cessite un cadre d\u2018 explicite spatial pour se concentrer sur la bonne vari\ue9t\ue9 au bon endroit. Cela implique une approche d\u2019\ue9valuation multicrit\ue8re (ECM), utilisant un ensemble de facteurs d\ue9terminants pour d\ue9limiter les domaines de mesurage pour les vari\ue9t\ue9s de f\ue9verole ( Vicia faba L.) et identifier les terres potentiellement appropri\ue9es dans une r\ue9gion et une zone sp\ue9cifiques en \uc9thiopie.

INFLUENCE OF TREATMENT OF SEED POTATO TUBERS WITH PLANT CRUDE ESSENTIAL OIL EXTRACTS ON PERFORMANCE OF THE CROP

Farmers in most developing countries store seed potato ( Solanum tuberosum L.) tubers in traditional storage that invariably leads to rapid deterioration in the quality of the seed tubers due to sprouting and aging. Thus, potato seed tubers senesce and are past their prime when planted. A pot experiment was conducted at Sirinka Agricultural Research Centre, in north-eastern Ethiopia, to evaluate the effect of treating seed potato tubers with crude plant essential oil extracts, on the growth and yield of the potato crop. Treatments consisted of seed potato tubers treated with dill weed, spearmint, black cumin and eucalyptus crude essential oil extracts, each applied at 45, 90 and 135 mg kg-1 of potato tubers for one month, plus a control treatment. The control consisted of untreated tubers. Results revealed that potato plants grown from seed tubers treated with oil extracts from dill weed, spearmint, and eucalyptus at 135 mg kg-1, took the longest time to sprout, flower, and tubers to mature. Potato plants grown from seed tubers treated with dill weed, spearmint, black cumin and eucalyptus crude essential oil extracts at 135 mg kg-1 were 23 - 38% taller than plants from the untreated seed tubers. Similarly, potatoes from these treatments had 21 - 89% more numbers of leaves compared to plants from the untreated seed tubers. Crude essential oils from dill weed at the concentrations of 90 and 135 mg kg-1 and eucalyptus at 135 mg kg-1, had the greatest positive effects on growth and yield of the potato crop.Dans plusieurs pays en d\ue9veloppement, les paysans conservent les tubercules de pomme de terre ( Solanum tuberosum L.) en stockage traditionnel, ce qui est responsable de la d\ue9t\ue9rioration rapide de la qualit\ue9 des semences due au vieillissement et au bourgeonnement des tubercules. Alors, les tubercules de pomme de terre vieillissent et perdent leur fra\ueecheur avant d\u2019\ueatre plant\ue9. Une exp\ue9rimentation en pots a \ue9t\ue9 conduite au Centre de Recherche Agricole de Sirinka au North-Est de l\u2019Ethiopie pour \ue9valuer l\u2019effet du traitement des tubercules de pomme de terre avec des huiles essentiels sur la croissance et le rendement la culture subs\ue9quente. Les traitements consistaient en l\u2019utilisation des huiles essentielles de la fenouille, la menthe verte, du cumin noir et de l\u2019eucalyptus \ue0 diff\ue9rente concentrations (45, 90 et 135 mg kg-1) pour traiter les tubercules de pomme de terre pendant un mois, et un traitement t\ue9moin (tubercules non trait\ue9s).

Exploring barriers to the use of formal maternal health services and priority areas for action in Sidama zone, southern Ethiopia.

In 2015 the maternal mortality ratio for Ethiopia was 353 per 100,000 live births. Large numbers of women do not use maternal health services. This study aimed to identify factors influencing the use of maternal health services at the primary health care unit (PHCU) level in rural communities in Sidama zone, south Ethiopia in order to design quality improvement interventions. We conducted a qualitative study in six woredas in 2013: 14 focus group discussions (FGDs) and 44 in-depth interviews with purposefully selected community members (women, male, traditional birth attendants, local kebele administrators), health professionals and health extension workers (HEWs) at PHCUs. We digitally recorded, transcribed and thematically analysed the interviews and FGDs using Nvivo. The 'three delay model' informed the analytical process and discussion of barriers to the use of maternal health services. Lack of knowledge on danger signs and benefits of maternal health services; cultural and traditional beliefs; trust in TBAs; lack of decision making power of women, previous negative experiences with health facilities; fear of going to an unfamiliar setting; lack of privacy and perceived costs of maternal health services were the main factors causing the first delay in deciding to seek care. Transport problems in inaccessible areas were the main contributing factor for the second delay on reaching care facilities. Lack of logistic supplies and equipment, insufficient knowledge and skills and unprofessional behaviour of health workers were key factors for the third delay in accessing quality care. Use of maternal health services at the PHCU level in Sidama zone is influenced by complex factors within the community and health system. PHCUs should continue to implement awareness creation activities to improve knowledge of the community on complications of pregnancy and benefits of maternal health services. The health system has to be responsive to community's cultural norms and practices. The mangers of the woreda health office and health centres should take into account the available budgets; work on ensuring the necessary logistics and supplies to be in place at PHCU

Performance of three multi-species rapid diagnostic tests for diagnosis of Plasmodium falciparum and Plasmodium vivax malaria in Oromia Regional State, Ethiopia

BACKGROUND: Malaria transmission in Ethiopia is unstable and variable, caused by both Plasmodium falciparum and Plasmodium vivax. The Federal Ministry of Health (FMoH) is scaling up parasitological diagnosis of malaria at all levels of the health system; at peripheral health facilities this will be through use of rapid diagnostic tests (RDTs). The present study compared three RDT products to provide the FMoH with evidence to guide appropriate product selection. METHODS: Performance of three multi-species (pf-HRP2/pan-pLDH and pf-HRP2/aldolase) RDTs (CareStart, ParaScreen and ICT Combo) was compared with 'gold standard' microscopy at three health centres in Jimma zone, Oromia Regional State. Ease of RDT use by health extension workers was assessed at community health posts. RDT heat stability was tested in a controlled laboratory setting according to WHO procedures. RESULTS: A total of 2,383 patients with suspected malaria were enrolled between May and July 2009, 23.2% of whom were found to be infected with Plasmodium parasites by microscopy. All three RDTs were equally sensitive in detecting P. falciparum or mixed infection: 85.6% (95% confidence interval 81.2-89.4). RDT specificity was similar for detection of P. falciparum or mixed infection at around 92%. For detecting P. vivax infection, all three RDTs had similar sensitivity in the range of 82.5 to 85.0%. CareStart had higher specificity in detecting P. vivax (97.2%) than both ParaScreen and ICT Combo (p < 0.001 and p = 0.05, respectively). Health extension workers preferred CareStart and ParaScreen to ICT Combo due to the clear labelling of bands on the cassette, while the 'lab in a pack' style of CareStart was the preferred design. ParaScreen and CareStart passed all heat stability testing, while ICT Combo did not perform as well. CONCLUSIONS: CareStart appeared to be the most appropriate option for use at health posts in Ethiopia, considering the combination of quantitative performance, ease of use and heat stability. When new products become available, the choice of multi-species RDT for Ethiopia should be regularly re-evaluated, as it would be desirable to identify a test with higher sensitivity than the ones evaluated here

Mapping inequalities in exclusive breastfeeding in low- and middle-income countries, 2000–2018

Abstract: Exclusive breastfeeding (EBF)—giving infants only breast-milk for the first 6 months of life—is a component of optimal breastfeeding practices effective in preventing child morbidity and mortality. EBF practices are known to vary by population and comparable subnational estimates of prevalence and progress across low- and middle-income countries (LMICs) are required for planning policy and interventions. Here we present a geospatial analysis of EBF prevalence estimates from 2000 to 2018 across 94 LMICs mapped to policy-relevant administrative units (for example, districts), quantify subnational inequalities and their changes over time, and estimate probabilities of meeting the World Health Organization’s Global Nutrition Target (WHO GNT) of ≥70% EBF prevalence by 2030. While six LMICs are projected to meet the WHO GNT of ≥70% EBF prevalence at a national scale, only three are predicted to meet the target in all their district-level units by 2030

Trends in HIV/AIDS morbidity and mortality in Eastern 3 Mediterranean countries, 1990–2015: findings from the Global 4 Burden of Disease 2015 study

Objectives We used the results of the Global Burden of Disease 2015 study to estimate trends of HIV/AIDS burden in Eastern Mediterranean Region (EMR) countries between 1990 and 2015. Methods Tailored estimation methods were used to produce final estimates of mortality. Years of life lost (YLLs) were calculated by multiplying the mortality rate by population by age-specific life expectancy. Years lived with disability (YLDs) were computed as the prevalence of a sequela multiplied by its disability weight. Results In 2015, the rate of HIV/AIDS deaths in the EMR was 1.8 (1.4–2.5) per 100,000 population, a 43% increase from 1990 (0.3; 0.2–0.8). Consequently, the rate of YLLs due to HIV/AIDS increased from 15.3 (7.6–36.2) per 100,000 in 1990 to 81.9 (65.3–114.4) in 2015. The rate of YLDs increased from 1.3 (0.6–3.1) in 1990 to 4.4 (2.7–6.6) in 2015. Conclusions HIV/AIDS morbidity and mortality increased in the EMR since 1990. To reverse this trend and achieve epidemic control, EMR countries should strengthen HIV surveillance,and scale up HIV antiretroviral therapy and comprehensive prevention services
