    Get PDF
    The objective of this chapter is to review, from several literatures, the contribution of agriculture to climate change and the reciprocal effects of climate change on agriculture and the general consequent implications on human livelihoods and ecosystems. Human activities have already had a discernible impact on the earth’s climate leading to growing evidence of observable impacts of climate change on physical and biological systems. In no doubt, agriculture provides the world population of 7 billion with the food that we all eat every day. In addition, 1.4 billion people work in agriculture and more than 2.5 billion people sustain their livelihood on agriculture. But agriculture is one of the contributors of greenhouse gases to climate change and climate change affects agriculture in return. When the global mean temperature change increases beyond 3.5°C, most of the species will have very few suitable areas for their survival and will become extinct. Several hundred million people are seriously affected by climate change today, with several hundred thousand annual deaths. Human impacts of climate change include scarcity of freshwater resources, weather-related disasters, food insecurity due to agricultural loss, migration, and displacement due to loss of settlements. These recalled nations to limit their GHG emission, ensure sustainable ecosystem, food production, and economic development so as to calm down the impacts of climate change

    Roles of NGOs in Community Empowerment for Natural Resource Conservation: A case study of two NGOs in North Wollo, Ethiopia

    Get PDF
    This paper is a summary of a thesis submitted to the Kimmage Development Studies Centre, Dublin, in partial fulilment of the requirements for the degree of MA in Development Studies. The paper focuses on the work of two NGOs working in northern Ethiopia. It analyses the natural resource management programme components of these NGOs and their efforts at community empowerment, with particular focus on the issues of community participation, training/ awareness creation and institutional formation, together with challenges and the available opportunities. The thesis argues that the effective engagement of an NGO in community empowerment processes entails organisational orientation in terms of its vision, principles, goals, strategies and its activity components. The research utilised a qualitative approach using a purposive sampling method. It was found that in terms of their programme components, both organisations have yet to position themselves in a way that helps them address the existing power relations to facilitate the community empowerment process. Despite the NGOs’ efforts in awareness creation and community institutional formation, the community is still dependent on external agents to mobilise them for self-development activities. The thesis recommends that there is a need for raising the level of consciousness of the community, and the institutions established at the community level have to be in the form of an association fully controlled by the community, and not merely an instrument for control

    Urban Energy Transition and Technology Adoption: The Case of Tigrai, Northern Ethiopia

    Get PDF
    Dependency of urban Ethiopian households on rural areas for about 85 percent of their fuel needs is a significant cause of deforestation and forest degradation, resulting in growing fuel scarcity and higher firewood prices. One response to reducing the pressure on rural lands is for urban households to switch fuel sources (from fuelwood to electricity, for example) to slow deforestation and forest degradation and reduce indoor air pollution. However, such an energy transition is conditioned on the adoption of appropriate cooking appliances or stove technologies by the majority of users. This paper investigates urban energy transition and technology adoption conditions using a dataset of 350 urban households in Tigrai, in northern Ethiopia. Results suggest that the transition to electricity is affected by households adopting the electric mitad cooking appliance, which in turn is influenced by the level of education and income, among other things.urban energy transition, electric mitad cooking appliance, technology adoption, bivariate probit, Tigrai, Ethiopia

    Household Tree Planting in Tigrai, Northern Ethiopia: Tree Species, Purposes, and Determinants

    Get PDF
    Trees have multiple purposes in rural Ethiopia, providing significant economic and ecological benefits. Planting trees supplies rural households with wood products for their own consumption, as well for sale, and decreases soil degradation. We used cross-sectional household-level data to analyze the determinants of household tree planting and explored the most important tree attributes or purpose(s) that enhance the propensity to plant trees. We set up a sample selection framework that simultaneously took into account the two decisions of tree growers (whether or not to plant trees and how many) to analyze the determinants of tree planting. We used logistic regression to analyze the most important tree attributes that contribute to households’ tree-planting decisions. We found that land size, age, gender, tenure security, education, exogenous income, and agro-ecology increased both the propensity to plant trees and the amount of tree planting, while increased livestock holding impacted both decisions negatively. Our findings also suggested that households consider a number of attributes in making the decision to plant trees. These results can be used by policymakers to promote tree planting in the study area by trengthening tenure security and considering households’ selection of specific tree species for their attributes.tree plantin, tree species, tree attributes or purposes, sample selection, Tigrai, Ethiopia

    Rubella virus sero-prevalence and associated factors among non-vaccinated pregnant women in Northwest Ethiopia

    Get PDF
    Abstract Background: Rubella virus infection during pregnancy is associated with adverse fetal outcomes and reproductive failures. In Ethiopia, little is known about the extent of the disease and rubella vaccination is not widely available. The main aim of this study was to assess the sero-prevalence of the rubella virus infection and its associated risk factors among pregnant women. Methods: An institution based cross-sectional study was conducted in the antenatal clinics of Debre Markos and Debre Tabor hospitals of Amhara Region, Northwest Ethiopia from March to June2015. Study participants were recruited until the calculated sample size was achieved at both hospitals. Data on socio-demographic and factors associated with rubella virus infection were collected through a structured questionnaire. A 5ml blood sample was also collected from all study participants and tested for Immunoglobulin (Ig) G and IgM antibodies against rubella virus infection using enzyme immune assay (EIA) test at the Amhara Regional Health Research Laboratory Center, Bahir Dar. Data were analyzed using SPSS version 21 and frequencies, chi-square tests and Odds ratio were computed using a p value < 0.05 as a level of significance. Result: A total of 401 pregnant mothers were screened for rubella virus infection. The mean age of the study participants was 26.4 year (SD= 5.4) and the overall sero-prevalence of rubella anti-IgG was 46.4%. In connection, the sero-prevalence of anti-IgM among anti-IgG sero-positive cases was 3.2%. Pregnant women at first trimester (OR=2.49, 95% CI= 1.14-5.42) and HIV sero-status (OR= 0.33, 95% CI= 0.15-0.76) were factors found to be significantly associated with rubella anti-IgG sero-prevalence (p<0.05). Conclusion: The sero-prevalence of rubella virus infection among pregnant women was considered to be low, showing the high risk of a new infection. In addition to a comprehensive surveillance approach and efforts to determine rubella susceptibility profile among school-aged girls and women of childbearing age, it is also important to consider rubella vaccine in a national vaccination program.

    Methicillin-resistant Staphylococcus aureus with genotyping method among human immunodeficiency virus positive pediatric patients in Northwest Ethiopia: A cross-sectional study design

    Get PDF
    Abstract Background: Increasing evidence suggests that methicillin-resistant Staphylococcus aureus (MRSA) infections are becoming more prevalent throughout the human immunodeficiency virus (HIV) infected community. However, there is scarcity of data about the prevalence of MRSA among HIV positive pediatric patients in the study area. Objectives: To determine the prevalence and types of MRSA among S. aureus isolates of HIV positive pediatric patients in the Amhara National Regional State, Northwest Ethiopia. Methods: Pediatric patients who attended the clinic from December 2013 to April 2014 were included in the study. Genotype MRSA VER 3.0 was used for characterization of S. aureus isolates. This detected methicillin-resistance-mediating mecA and mecC genes and the bicomponent cytotoxic virulence factor Panton–Valentine leukocidin (PVL). Data were analyzed using SPSS version 20. Results: Among 126 S. aureus isolates, 37.3% and 11.9% were mecA and Panton–Valentine leukocidin gene positive, respectively. Patients of FHRH (P = 0.04) and DRH (P = 0.02) have statistical significance for mecA gene. Panton–Valentine leukocidin gene positive strains were about 97% less likelihood to be mecA gene positive (P = 0.001). Conclusion: A high prevalence of pathogenic MRSA strains among HIV positive pediatric patients was observed. Most of the MRSA types were hospital acquired. Hence, strict hygienic approaches by healthcare workers in hospitals should be implemented. In addition, screening and treatment of MRSA for HIV positive pediatric patients is recommended. [Ethiop.

    Profitability of bioethanol production: the case of Ethiopia

    Get PDF
    This research investigates the profitability of bioethanol production in Africa, taking Ethiopia as a case in point, and suggests an oil price threshold beyond which biofuels may be profitable. Specifically, the study analyzes the viability of producing bioethanol from molasses in the context of Ethiopia, using data from a biofuels investment survey by EEPFE/EDRI in 2010. We draw on investment theory as our underlying conceptual framework and we employ unit cost analysis for our empirical analysis. Findings reveal that bioethanol production (from molasses) in Africa/Ethiopia can be quite viable and the biofuels industry can be viewed as a way out of poverty. This is a case study involving a few observations because of the small size of the universe of producers studied; hence the need for further analysis as the sector expands.Key words: profitability; bioethanol; oil price threshold; Ethiopia; AfricaJEL Codes: Q56, Q4

    Bacterial profile and antimicrobial susceptibility pattern of neonatal sepsis in Felege-Hiwot Referral Hospital, Bahir Dar, northwest Ethiopia: A cross-sectional study design

    AbstractBackground: Neonatal sepsis is a life-threatening medical condition that occurs when host and pathogen interaction leads to organ/tissue damage. Determining the bacterial profile and the antimicrobial susceptibility pattern, and associated factors, in certain geographic regions is vital for rapid empirical medical decisions.Objective: To assess the bacterial profile, antimicrobial susceptibility pattern, and factors associated with neonatal sepsis, in Felege-Hiwot Referral Hospital, Ethiopia.Methods: A facility-based cross-sectional study was conducted from April 2018 to July 2018. A total of 412 neonates were included in the study. Socio-demographic and clinical data were collected using a structured and pre-tested questionnaire. About 2ml of blood sample was withdrawn from each participant, and processed for bacterial identification and susceptibility testing, following 2017 Clinical and Laboratory Standards Institute guidelines. Data were analysed using Statistical Package for the Social Sciences version 23. Logistic regressions were used to determine the association between independent variables and dependent variables in relation to bacterial profiles and antimicrobial susceptibility patterns. Odds ratios, and their 95% confidence intervals, were calculated, and the results were considered statistically significant at a p-value less than 0.05.Results: Of the 412 neonates who were enrolled, 41.3% (170/412) were positive for blood culture. Klebsiella pneumoniae, 28.2% (48/170) was the predominant isolate, followed by Staphylococcus aureus, 24.7% (42/170). The majority of the isolates developed resistance to ampicillin and penicillin. The overall proportion of multidrug resistance was 78.2% (133/170). Preterm (<37 weeks) [AOR = 2.049; 95% CI: 1.151, 3.647], low birth weight (<2,500gm) [AOR = 2.357; 95% CI: 1.352, 4.109], prolonged rupture of membrane (≥18 hours) [AOR = 4.282; 95% CIL: 1.615, 11.354], and caesarean section modes of delivery [AOR = 2.826; 95% CI: 1.618, 4.936] showed statistical association with bacteriologically confirmed neonatal sepsis.Conclusions: The majority (78.2%) of presumptive neonatal sepsis cases tested positive for blood culture. Klebsiella pneumoniae and Staphylococcus aureus were the leading isolates recovered from neonatal sepsis cases. Most of the bacterial isolates from NS cases were resistant to multiple classes of antibiotic. Auspiciously, majority of these isolates were susceptible to ciprofloxacin; as such this replication inhibitor antibiotic could be a choice of physicians for empirical treatment decision. Since it is a single facility based study, further study is recommended. [Ethiop. J.

    BACKGROUND: Tuberculosis and human immunodeficiency virus (HIV) are among the major health problems in Ethiopia. This study assessed the proportion of tuberculosis lymphadenitis (TBLN), HIV infection and their co-infection among TBLN presumptive individuals at the selected hospitals in NorthwestEthiopia.METHODS: Institution based cross sectional study was carried out. Data on demographic and clinical variables were collected with standardized questionnaire. Microbiological culture was done on specimen obtained by fine needle aspirates. The HIV status was determined by rapid anti-HIV antibody test. Data was entered and scrutinized using SPSS version 20 statistical packages. A stepwise logistic regression model was used. The result was considered as statistically significant at P<0. 05.RESULTS: A total of 381 lymphadenitis patients were included in the study. The overall prevalence of TBLN and HIV were at 250(65.6%) and 9(2.4%), respectively and their co-infection was at 6(2.4%). Based on the cytological examination, 301(79.0%) of them were diagnosed as TBLN. The age group, (P=0.01) and residency, (P=0.01) were found significantly associated with TBLN. Similarly, unsafe sex was also statistically significant for HIV infection (P=0.007).CONCLUSION: Tuberculosis lymphadenitis is the leading cause of TB and lymphadenitis in the region. However, TBLN-HIV coinfection was promisingly low. High rate of discrepancy was noticed between cytological and culture results. Hence, the TBLN diagnostic criteria shall pursue revision
