Perceived Impacts of Climate Change and Disaster Risk Management by Rural Communities in Ethiopia

In developing countries including Ethiopia changing pattern of rainfall, increasing temperature, recurrent drought, massive land degradation, and poor performance of agricultural sector contribute for failure to meet the growing demands for food for the rural communities and left dependent on foreign food aid and seasonal migration. This study aims at examining the perceived impacts of climate change and disaster risk management by rural communities in Ethiopia. Cross-sectional socio-economic data were used. Dejen district was purposively selected as it is highly susceptible to climate related problems. Stratified and snowball sampling techniques were employed to select a sample of 398 households. Household survey was employed to collect data on climate change impacts perceived by local communities. Focus group discussions were carried out using guiding questions and seasonal calendar. Key informant interviews were used to triangulate households\u27 perceived climate change impacts. Field observations were used to observe biophysical, economic, social, and institutional features of the district. The results indicate that crop pests, soil erosion, crop disease, frost, drought, flood, hailstorm, and erratic rainfall were the major contributing factor for the loss of 50,555 quintals of agricultural cops over the period 2009-2016. The community seasonal calendar indicate that erratic rainfall, hailstorm, dry period, flood, landslide, livestock disease, crop disease and pests, and human diseases were the major climatic events in the study areas of rural communities. The lowland households were more susceptible to climate change impacts. Policy priority should be given based on the agro-ecology and households livelihood assets vulnerability level

Newborn care seeking practices in Central and Southern Ethiopia and implications for community based programming

Background: In Ethiopia, close to 120,000 newborns die annually and newborn mortality now constitutes 42% of under-five deaths. The use of health care for newborn illnesses is very limited.Objective: To investigate local perspectives and practices related to newborn care-seeking and the factors affecting them.Methods: Key informant interviews with grandmothers and in-depth interviews with mothers, TBAs and fathers were used to collect data in four communities in Sidama Zone, Southern Nations, Nationalities and Peoples Region and East Shewa Zone and West Arsi Zone in Oromia Region. Analysis consisted of manual thematic coding of the data and synthesis for write-up.Results: Locally recognized signs and types of illness only partially conform to medically recognized danger signs. Households apply home therapies, traditional healers or health facilities to get treatment for sick newborns. Lack of resources, transportation and appropriate treatment are barriers to making use of health facilities.Conclusion: Local conceptions of newborn illnesses, inadequate recognition of danger signs, using traditional treatment, and lack of financial resources, transportation and appropriate treatment constrain or delay resorting to health facilities for newborn illnesses

Ectoparasites of Sheep and Goats in North-West Amhara Regional State, Ethiopia

A cross-sectional study on ectoparasites of sheep (n=738) and goats (n=492) was conducted in Northwestern Amhara Regional State of Ethiopia from October 2009 to April 2010 to determine the prevalence of major ectoparasites of sheep and goats and the associated risk factors. Out of the clinically examined animals, 331(44.9%) sheep and 214 (43.5%) goats were infested with one or more ectoparasites. Ectoparasites identified in sheep were Damalinia ovis (30.9%), Mellophagus ovinus (10.8%), ticks (3.9%), Linognathus species (3.1%) and flea (1.1%). Among goats, Linognathus species, ticks, flea and demodectic mange were identified with respective prevalence of 27%, 17.7%, 2.6% and 2.2%. Sheep in midland were 3.7 and 2.3 times more at risk for Damalinia ovis infestation than sheep in highland and lowland, respectively and also goats in midland were 1.8 times at risk for Linognathus species than lowland sheep (P < 0.05). Sheep poor in body condition were 1.9 times more at risk for Damalinia ovis than good body condition sheep and goats poor in body condition were 3.5 times more at risk for Linognathus species than good body condition goats (P< 0.05). Age and wool length of sheep were important predictors for the presences of Mellophagus ovinus on highland sheep. The prevalence of Mellophagus ovinus was significantly higher in young and long wool sheep than in adult and short wool sheep (P < 0.05). The observed overall prevalence is generally high which may result in enormous economic losses through decreased production and productivity, damages to the skin and deaths of the animal which requires an immediate attention and professional intervention.Key words: Ectoparasites, Ethiopia, Goat, Prevalence, Risk factors, Sheep

Status of the ANAIS Dark Matter Project at the Canfranc Underground Laboratory

The ANAIS experiment aims at the confirmation of the DAMA/LIBRA signal. A detailed analysis of two NaI(Tl) crystals of 12.5 kg each grown by Alpha Spectra will be shown: effective threshold at 1 keVee is at reach thanks to outstanding light collection and robust PMT noise filtering protocols and the measured background is well understood down to 3 keVee, having quantified K, U and Th content and cosmogenic activation in the crystals. A new detector was installed in Canfranc in March 2015 together with the two previous modules and preliminary characterization results will be presented. Finally, the status and expected sensitivity of the full experiment with 112 kg will be reviewed.Comment: Contributed to the 11th Patras Workshop on Axions, WIMPs and WISPs, Zaragoza, June 22 to 26, 201

Background model of NaI(Tl) detectors for the ANAIS Dark Matter Project

A thorough understanding of the background sources is mandatory in any experiment searching for rare events. The ANAIS (Annual Modulation with NaI(Tl) Scintillators) experiment aims at the confirmation of the DAMA/LIBRA signal at the Canfranc Underground Laboratory (LSC). Two NaI(Tl) crystals of 12.5 kg each produced by Alpha Spectra have been taking data since December 2012. The complete background model of these detectors and more precisely in the region of interest will be described. Preliminary background analysis of a new 12.5 kg crystal received at Canfranc in March 2015 will be presented too. Finally, the power of anticoincidence rejection in the region of interest has been analyzed in a 4x 5 12.5 kg detector matrix.Comment: Contributed to the 11th Patras Workshop on Axions, WIMPs and WISPs, Zaragoza, June 22 to 26, 201

Production and relevance of cosmogenic radionuclides in NaI(Tl) crystals

The cosmogenic production of long-lived radioactive isotopes in materials is an hazard for experiments demanding ultra-low background conditions. Although NaI(Tl) scintillators have been used in this context for a long time, very few activation data were available. We present results from two 12.5 kg NaI(Tl) detectors, developed within the ANAIS project and installed at the Canfranc Underground Laboratory. The prompt data taking starting made possible a reliable quantification of production of some I, Te and Na isotopes with half-lives larger than ten days. Initial activities underground were measured and then production rates at sea level were estimated following the history of detectors; a comparison of these rates with calculations using typical cosmic neutron flux at sea level and a selected description of excitation functions was also carried out. After including the contribution from the identified cosmogenic products in the detector background model, we found that the presence of 3H in the crystal bulk would help to fit much better our background model and experimental data. We have analyzed the cosmogenic production of 3H in NaI, and although precise quantification has not been attempted, we can conclude that it could imply a very relevant contribution to the total background below 15 keV in NaI detectors.Comment: Proceedings of the Low Radioactivity Techniques 2015 workshop, March 2015, Seattle (US

Analysis of backgrounds for the ANAIS-112 dark matter experiment

The ANAIS (Annual modulation with NaI(Tl) Scintillators) experiment aims at the confirmation or refutation of theDAMA/LIBRA positive annual modulation signal in the low energy detection rate, using the same target and technique, at the Canfranc Underground Laboratory (LSC) in Spain. ANAIS-112, consisting of nine 12.5 kg NaI(Tl) modules produced by Alpha Spectra Inc. in a 3x3matrix configuration, is taking data smoothly in "dark matter search" mode since August, 2017, after a commissioning phase and operation of the first detectors during the last years in various setups. A large effort has been carried out withinANAIS to characterize the background of sodium iodide detectors, before unblinding the data and performing the first annual modulation analysis. Here, the background models developed for all the nine ANAIS-112 detectors are presented. Measured spectra from threshold to high energy in different conditions are well described by the models based on quantified activities independently estimated following several approaches. In the region from 1 to 6 keVee the measured, efficiency corrected background level is 3.58+-0.02 keV-1 kg-1 day-1; NaI crystal bulk contamination is the dominant background source being 210Pb, 40K, 22Na and 3H contributions the most relevant ones. This background level, added to the achieved 1 keVee analysis threshold (thanks to the outstanding light collection and robust filtering procedures developed), allow ANAIS-112 to be sensitive to the modulation amplitude measured by DAMA/LIBRA, and able to explore at three sigma level in 5 years the WIMP parameter region singled out by this experiment.Comment: Final version for publicatio

'People have started to deliver in the facility these days': a qualitative exploration of factors affecting facility delivery in Ethiopia

Objectives To understand the recent rise in facility deliveries in Ethiopia. Design A qualitative study. Setting Four rural communities in two regions of Ethiopia. Participants 12 narrative, 12 in-depth interviews and four focus group discussions with recently delivered women; and four focus group discussions with each of grandmothers, fathers and community health workers. Results We found that several interwoven factors led to the increase in facility deliveries, and that respondents reported that the importance of these factors varied over time. The initial catalysts were a saturation of messages around facility delivery, improved accessibility of facilities, the prohibition of traditional birth attendants, and elders having less influence on deciding the place of delivery. Once women started to deliver in facilities, the drivers of the behaviour changed as women had positive experiences. As more women began delivering in facilities, families shared positive experiences of the facilities, leading to others deciding to deliver in a facility. Conclusion Our findings highlight the need to employ strategies that act at multiple levels, and that both push and pull families to health facilities
