    Le changement climatique et la variabilité ont été détectés en Éthiopie. Les petits exploitants et les agriculteurs de subsistance, les éleveurs et les ménages tributaires des forêts sont les plus touchés par les risques liés au climat. Ils doivent avoir une perception du changement climatique afin d'y répondre en élaborant des stratégies d'adaptation et/ou d'adaptation. Les perceptions locales et les stratégies d'adaptation fournissent une base cruciale pour les mesures communautaires d'adaptation au changement climatique. Cette étude a été spécifiquement conçue pour (1) évaluer la perception et les connaissances des ménages en matière de changement et/ou de variabilité climatique, et (2) établir les changements observés dans les paramètres climatiques avec les perceptions de la communauté et les anomalies climatiques. La méthode d'échantillonnage aléatoire stratifié intentionnel a été utilisée pour recueillir des informations auprès de 355 ménages de l'échantillon pour des entretiens individuels complétés par des discussions de groupe et des entretiens avec des informateurs clés. L'analyse des données climatiques observées et satellitaires pour le district d'étude a montré que les températures maximales et minimales moyennes pour la période 1983–2014 ont augmenté de 0,047 et 0,028 °C/an, respectivement. Cependant, les précipitations totales ont diminué de 10,16 mm par an. En saison, les précipitations ont diminué de 2,198, 4,541, 1,814 et 1,608 mm par an pour les saisons éthiopienne d'été, de printemps, d'automne et d'hiver, respectivement. De même, la température maximale moyenne de la zone d'étude avait montré un accroissement de 0,035, 0,049, 0,044 et 0,065 °C par an pour les saisons de printemps, d'hiver, d'automne et d'été, respectivement. La variation climatique observée a été confirmée par la perception des gens. Considérant que ce qui existait avant il y a 30 ans était normal, une augmentation de la température, une augmentation de la fréquence des sécheresses, une diminution des précipitations totales, le caractère erratique de sa distribution et le retard de son apparition avaient été perçus par 88, 70, 97, 80 et 94% des répondants, respectivement, à l'heure actuelle-2015. La déforestation en tant que facteur occasionnel du changement et de la variabilité climatiques avait été perçue par 99,7 % des répondants. Cela avait également été confirmé par des études scientifiques car il émet du dioxyde de carbone et est le principal moteur du changement et de la variabilité climatiques. Les connaissances autochtones, y compris les prévisions climatiques, ont été utilisées par les gens pour mettre en œuvre leurs activités agricoles quotidiennes. Par conséquent, la science devrait être intégrée à la perception et aux connaissances autochtones des personnes pour trouver une solution concrète aux impacts du changement climatique et de la variabilité sur les moyens de subsistance humains. Se ha detectado cambio climático y variabilidad en Etiopía. Los pequeños agricultores y agricultores de subsistencia, los pastores y los hogares dependientes de los bosques son los más afectados por los peligros relacionados con el clima. Tienen que tener percepción del cambio climático para poder responder a él a través de la elaboración de estrategias de afrontamiento y/o adaptación. Las percepciones locales y las estrategias de afrontamiento proporcionan una base crucial para las medidas de adaptación al cambio climático basadas en la comunidad. Este estudio fue diseñado específicamente para (1) evaluar la percepción y el conocimiento de los hogares sobre el cambio climático y/o la variabilidad, y (2) establecer los cambios observados en los parámetros climáticos con las percepciones de la comunidad y las anomalías climáticas. El método de muestreo aleatorio estratificado se ha utilizado para recopilar información de 355 hogares de muestra para entrevistas individuales complementadas por discusiones grupales y entrevistas con informantes clave. El análisis de los datos climáticos observados y satelitales para el distrito de estudio mostró que la temperatura media máxima y mínima para el período 1983–2014 ha aumentado en 0.047 y 0.028 ° C/año, respectivamente. Sin embargo, la precipitación total ha disminuido en 10,16 mm por año. Estacionalmente, las precipitaciones han disminuido en 2,198, 4,541, 1,814 y 1,608 mm anuales para las temporadas etíopes de verano, primavera, otoño e invierno, respectivamente. Del mismo modo, la temperatura máxima media del área de estudio había mostrado un incremento de 0.035, 0.049, 0.044 y 0.065 °C por año para las temporadas de primavera, invierno, otoño y verano, respectivamente. La variación climática observada ha sido confirmada por la percepción de las personas. Teniendo en cuenta lo que habían sido las situaciones existentes antes de hace 30 años como normales, un aumento de la temperatura, un aumento de la frecuencia de la sequía, una disminución de la precipitación total, el carácter errático de su distribución y la tardanza de su inicio habían sido percibidos por el 88, 70, 97, 80 y 94% de los encuestados, respectivamente, en el momento actual-2015. La deforestación como factor casual del cambio climático y la variabilidad había sido percibida por el 99,7% de los encuestados. Esto también había sido confirmado por estudios científicos, ya que emite dióxido de carbono y es el principal impulsor del cambio climático y la variabilidad. Los conocimientos indígenas, incluidas las predicciones climáticas, han sido utilizados por las personas para implementar sus actividades agrícolas cotidianas. Por lo tanto, la ciencia debe integrarse con la percepción y el conocimiento indígena de las personas para encontrar soluciones concretas para el cambio climático y los impactos de la variabilidad en los medios de vida humanos. Climate change and variability has been detected in Ethiopia. Smallholder and subsistence farmers, pastoralists and forest-dependent households are the most hit by climate-related hazards. They have to have perception of climate change in order to respond it through making coping and/or adaptation strategies. Local perceptions and coping strategies provide a crucial foundation for community-based climate change adaptation measures. This study was specifically designed to (1) assess households' perception and knowledge in climate change and/or variability, and (2) establish the observed changes in climate parameters with community perceptions and climate anomalies. Purposive stratified random sampling method has been used to gather information from 355 sample households for individual interviews supplemented by group discussion and key informants interviews. The analysis of observed and satellite climate data for the study district showed that mean maximum and minimum temperature for the period 1983–2014 has increased by 0.047 and 0.028 °C/year, respectively. However, the total rainfall has declined by 10.16 mm per annum. Seasonally, the rainfall has declined by 2.198, 4.541, 1.814 and 1.608 mm per annum for Ethiopian summer, spring, autumn and winter seasons, respectively. Similarly, the mean maximum temperature of the study area had showed an increment of 0.035, 0.049, 0.044 and 0.065 °C per year for spring, winter, autumn and summer seasons, respectively. The observed climate variation has been confirmed by people's perception. Considering what had been the existed situations before 30 years ago as normal, an increase in temperature, an increase in drought frequency, a decrease in total rainfall, erratic nature of its distribution and the tardiness of its onset had been perceived by 88, 70, 97, 80 and 94% of the respondents, respectively, at current time—2015. Deforestation as a casual factor of climate change and variability had been perceived by 99.7% of the respondents. This had been also confirmed by scientific studies as it emits carbon dioxide and is the main driver of climate change and variability. Indigenous knowledge, including climate predictions, has been used by people to implement their day-to-day agricultural activities. Therefore, science should be integrated with the perception and indigenous knowledge of people to come up with concrete solution for climate change and variability impacts on human livelihoods. تم الكشف عن تغير المناخ وتقلبه في إثيوبيا. صغار المزارعين ومزارعي الكفاف والرعاة والأسر التي تعتمد على الغابات هم الأكثر تضررًا من المخاطر المتعلقة بالمناخ. يجب أن يكون لديهم تصور لتغير المناخ من أجل الاستجابة له من خلال وضع استراتيجيات للتكيف و/أو التكيف. توفر التصورات المحلية واستراتيجيات التكيف أساسًا حاسمًا لتدابير التكيف مع تغير المناخ المجتمعية. تم تصميم هذه الدراسة خصيصًا من أجل (1) تقييم تصور الأسر ومعرفتها بتغير المناخ و/أو تقلبه، و (2) تحديد التغيرات الملحوظة في المعلمات المناخية مع تصورات المجتمع والشذوذ المناخي. تم استخدام طريقة أخذ العينات العشوائية الطبقية الهادفة لجمع المعلومات من 355 أسرة من العينة لإجراء مقابلات فردية تكملها مناقشة جماعية ومقابلات مع المخبرين الرئيسيين. أظهر تحليل البيانات المناخية المرصودة والأقمار الصناعية لمنطقة الدراسة أن متوسط درجة الحرارة القصوى والدنيا للفترة 1983–2014 قد زاد بمقدار 0.047 و 0.028 درجة مئوية/سنة على التوالي. ومع ذلك، انخفض إجمالي هطول الأمطار بمقدار 10.16 مم سنويًا. انخفض هطول الأمطار موسميًا بمقدار 2.198 و 4.541 و 1.814 و 1.608 ملم سنويًا لفصول الصيف والربيع والخريف والشتاء الإثيوبية على التوالي. وبالمثل، أظهر متوسط درجة الحرارة القصوى لمنطقة الدراسة زيادة قدرها 0.035 و 0.049 و 0.044 و 0.065 درجة مئوية سنويًا لفصول الربيع والشتاء والخريف والصيف، على التوالي. تم تأكيد التباين المناخي الملحوظ من خلال تصور الناس. بالنظر إلى الحالات التي كانت موجودة قبل 30 عامًا على أنها طبيعية، فإن زيادة في درجة الحرارة، وزيادة في تواتر الجفاف، وانخفاض في إجمالي هطول الأمطار، والطبيعة غير المنتظمة لتوزيعها وتأخر ظهورها قد أدركها 88 و 70 و 97 و 80 و 94 ٪ من المستجيبين، على التوالي، في الوقت الحالي 2015. اعتبر 99.7 ٪ من المستجيبين إزالة الغابات كعامل عرضي لتغير المناخ وتقلبه. وقد أكدت الدراسات العلمية ذلك أيضًا لأنه ينبعث منه ثاني أكسيد الكربون وهو المحرك الرئيسي لتغير المناخ وتقلبه. استخدم الناس معارف السكان الأصليين، بما في ذلك التنبؤات المناخية، لتنفيذ أنشطتهم الزراعية اليومية. لذلك، يجب دمج العلم مع التصور والمعارف الأصلية للناس للتوصل إلى حل ملموس لتغير المناخ وآثار التقلبات على سبل عيش الإنسان.

    To meet sustainable development goals and address concerns on climate change, much of the world's energy demand is expected to be delivered from clean alternative energy sources. Small-scale wind turbines have proven to be applicable for off-grid electrification. The objective of this study is to present the details on the design and manufacture of a 1 kW wind turbine blade for specified conditions. Blade element moment theory is adopted in the design of the geometry of the blade. Accordingly, the aerodynamic analysis on NACA 64A410 airfoil resulted in a blade radius of 1.95m, an overall twist angle of 31°, and a gradually tapering chord length of 0.062m at the root and 0.247m at the tip of the blade. Then, the wind turbine blades are manufactured from fiberglass (mat350g), resin, catalyst, and gelcoat. Experimental results reveal the wind turbine blades started producing power at a cut-in wind speed of 3m/s. The maximum power achieved during the testing process was 900W at a hub wind velocity of 9m/s. This is lower than the expected 1000W theoretical power output due to not perfect workmanship in the manufacture of the wind turbine blades. This study will help in building local manufacturing facilities and enhance rural electrification through off-grid technologies.

    Le secteur agricole reste la principale source de moyens de subsistance des communautés rurales en Éthiopie, mais le défi du changement climatique continue de constituer une grave menace pour son développement. Cette étude a examiné les facteurs affectant les décisions des petits exploitants agricoles d'adopter des options d'adaptation au changement climatique dans l'ouest de l'Éthiopie à l'aide de données recueillies auprès de 400 ménages échantillonnés. L'indice de satisfaction des précipitations et le modèle logit multinomial ont été utilisés pour analyser l'exposition des agriculteurs à la variabilité climatique et aux facteurs qui façonnent les stratégies d'adaptation des agriculteurs. Les résultats de l'étude ont montré que la majorité des agriculteurs sont fortement exposés au changement climatique à la fois en termes de pluviométrie variable et d'augmentation de la température. En réponse, pour s'adapter à l'impact du changement climatique, les agriculteurs participaient aux pratiques agronomiques, à la diversification des moyens de subsistance, à la conservation des sols et de l'eau et à l'irrigation à petite échelle en tant qu'options d'adaptation dominantes. Il est également observé que l'adoption de pratiques agronomiques a été considérablement influencée par le capital social, l'expérience des mauvaises récoltes et l'accès à l'alerte précoce. Il a été constaté que le genre du ménage, l'éducation et la propriété du bétail avaient une relation négative avec la diversification des moyens de subsistance. L'étude a également révélé que les mesures de conservation des sols et de l'eau sont affectées positivement par la perception de l'augmentation de la température, l'exposition aux systèmes d'alerte précoce et la plus grande taille des terres cultivées. En outre, l'adoption de l'irrigation à petite échelle a été considérablement influencée par l'accès au crédit, le capital social et le statut éducatif des chefs de famille. Par conséquent, le résultat implique que les programmes et les politiques conçus pour freiner les calamités du changement climatique devraient mettre l'accent sur la création de systèmes d'alerte précoce efficaces pour sensibiliser les agriculteurs, atteindre les agriculteurs avec des institutions de microfinance efficaces et encourager les liens des agriculteurs avec de nombreuses coopératives sociales. El sector agrícola sigue siendo la principal fuente de sustento para las comunidades rurales de Etiopía, pero el desafío del cambio climático sigue representando una grave amenaza para su desarrollo. Este estudio investigó los factores que afectan las decisiones de los pequeños agricultores de adoptar opciones de adaptación al cambio climático en el oeste de Etiopía utilizando datos recopilados de 400 hogares muestreados. El Índice de Satisfacción de Lluvias y el Modelo Logit Multinomial se utilizaron para analizar la exposición de los agricultores a la variabilidad climática y los factores que dan forma a las estrategias de adaptación de los agricultores. Los hallazgos del estudio mostraron que la mayoría de los agricultores están experimentando una alta exposición al cambio climático tanto en términos de precipitaciones variables como de aumento de la temperatura. En respuesta, para adaptarse al impacto del cambio climático, los agricultores estaban participando en las prácticas agronómicas, la diversificación de los medios de vida, el ahorro de suelo y agua y el riego a pequeña escala como las opciones de adaptación dominantes. También se observa que la adopción de prácticas agronómicas se vio afectada significativamente por el capital social, la experiencia de fracaso de los cultivos y el acceso a la alerta temprana. Se encontró que el género del hogar, la educación y la propiedad del ganado tenían una relación negativa con la diversificación de los medios de vida. El estudio reveló además que las medidas de conservación del suelo y el agua se ven afectadas positivamente por la percepción del aumento de la temperatura, la exposición a sistemas de alerta temprana y el mayor tamaño de las tierras cultivadas. Además, la adopción del riego a pequeña escala se vio influenciada significativamente por el acceso al crédito, el capital social y el estado educativo de los jefes de hogar. En consecuencia, el resultado implica que los programas y políticas diseñados para frenar las calamidades del cambio climático deben enfatizar la creación de sistemas efectivos de alerta temprana para aumentar la conciencia de los agricultores, llegar a los agricultores con instituciones de microfinanzas efectivas y fomentar los lazos de los agricultores con muchas cooperativas sociales. The agricultural sector remains the main source of livelihood for rural communities in Ethiopia, but the challenge of changing climate continues to pose a serious threat to its development. This study investigated factors affecting smallholder farmers' decisions to adopt adaptation options to climate change in West Ethiopia using data collected from 400 sampled households. The Rainfall Satisfaction Index and Multinomial Logit Model were used to analyze farmers' exposure to climate variability and factors that shape farmers' adaptation strategies. The findings of the study showed that the majority of farmers are experiencing high exposure to climate change both in terms of variable rainfall and rising temperature. In response, to adapt to the impact of climate change farmers were participating in agronomic practices, livelihood diversification, soil and water conservation, and small-scale irrigation as the dominant adaptation options. It is also observed that adopting agronomic practices was significantly impacted by social capital, crop failure experience, and access to early warning. Gender of the household, education, and livestock ownership were found to have a negative relationship with livelihood diversification. The study further revealed that soil and water conservation measures are positively affected by perception of temperature increment, exposure to early warning systems, and larger size of cultivated land. In addition, the adoption of small-scale irrigation was significantly influenced by access to credit, social capital, and the educational status of household heads. Consequently, the result implies that programs and policies designed to curb the calamities of climate change should emphasize creating effective early warning systems to increase farmer awareness, reach farmers with effective microfinance institutions, and encourage farmers' ties to many social cooperatives. لا يزال القطاع الزراعي المصدر الرئيسي لسبل عيش المجتمعات الريفية في إثيوبيا، لكن التحدي المتمثل في تغير المناخ لا يزال يشكل تهديدًا خطيرًا لتنميته. بحثت هذه الدراسة في العوامل التي تؤثر على قرارات صغار المزارعين باعتماد خيارات التكيف مع تغير المناخ في غرب إثيوبيا باستخدام البيانات التي تم جمعها من 400 أسرة تم أخذ عينات منها. تم استخدام مؤشر الرضا عن هطول الأمطار ونموذج المنطق متعدد الحدود لتحليل تعرض المزارعين لتقلبات المناخ والعوامل التي تشكل المزارعين واستراتيجيات التكيف. أظهرت نتائج الدراسة أن غالبية المزارعين يعانون من ارتفاع التعرض لتغير المناخ من حيث هطول الأمطار المتغير وارتفاع درجة الحرارة. واستجابة لذلك، وللتكيف مع تأثير تغير المناخ، كان المزارعون يشاركون في الممارسات الزراعية، وتنويع سبل العيش، والحفاظ على التربة والمياه، والري على نطاق صغير كخيارات التكيف السائدة. كما لوحظ أن اعتماد الممارسات الزراعية تأثر بشكل كبير برأس المال الاجتماعي، وتجربة فشل المحاصيل، والوصول إلى الإنذار المبكر. وجد أن جنس الأسرة والتعليم وملكية الماشية لها علاقة سلبية بتنويع سبل العيش. وكشفت الدراسة كذلك أن تدابير الحفاظ على التربة والمياه تتأثر بشكل إيجابي بتصور زيادة درجة الحرارة، والتعرض لأنظمة الإنذار المبكر، وحجم أكبر من الأراضي المزروعة. بالإضافة إلى ذلك، تأثر اعتماد الري على نطاق صغير بشكل كبير بالوصول إلى الائتمان ورأس المال الاجتماعي والوضع التعليمي لرب الأسرة. وبالتالي، فإن النتيجة تعني أن البرامج والسياسات المصممة للحد من كوارث تغير المناخ يجب أن تركز على إنشاء أنظمة فعالة للإنذار المبكر لزيادة وعي المزارعين، والوصول إلى المزارعين بمؤسسات فعالة للتمويل الأصغر، وتشجيع روابط المزارعين بالعديد من التعاونيات الاجتماعية.

    Electricity supply in Ethiopia is extremely antiquated. Most of the remote rural areas of Ethiopia are not yet electrified. Electrifying these remote areas by extending grid system is difficult and costly. Melkey Hera village is one of a rural community situated in western Ethiopia. In this village, extension of the grid is not yet practical. As the current international trend in rural electrification is to utilize renewable energy resources; solar, wind, biomass, and micro hydro power systems can be seen as alternatives. Therefore, the target of this paper is to investigate the viability of a micro hydro, Photo Voltaic (PV) and Diesel Generator-battery hybrid power system options to come up with the best techno-economic and optimum configuration for supplying electricity to this village. The study was performed by an assessment of the predicted village energy demand, the available renewable energy resources, and then using the software called HOMER. The best hybrid system type was described and the optimization of the system configuration was also done. Furthermore, through the simulation of different configuration of the supply system, the optimal mini-grid hybrid system design was established to combine hydro, solar PV, battery energy storage and diesel generator. This system demonstrated to be more reliable in operation, and the most cost-effective for the required level of service. The role of energy storage in system operation also demonstrated to offer additional operational advantages in-terms of reliability and cost savings. Overall, the design results show that the majority of energy obtained from hydropower, which accounts 79%, the PV module covers 20%, and diesel generator is only 1% of the total load consumption. The obtained hybrid system is cost competitive with $\$$0.133/kWh, which is somewhat good to satisfy the community needs. However, this is more than current energy price in Ethiopia which $\$$0.06/kWh. If due-merit given to the electricity deficiency of the country, it would play major role in improvement of life quality of community living in rural areas. From environmental standpoint, the renewable fraction of the project is 99%, which shows the system is environmentally friendly. Finally, this study identified that off grid hybrid micro hydro-PV-DG-battery bank energy system is cost effective and environmentally friendly in delivering power for rural areas far from the grid. Moreover, the study provides valuable information to the government and Non-government organization (NGO) about the renewable energy potential of the country for a rural electrification project in Ethiopia.

    Electricity supply in Ethiopia is extremely antiquated. Most of the remote rural areas of Ethiopia are not yet electrified. Electrifying these remote areas by extending grid system is difficult and costly. Melkey Hera village is one of a rural community situated in western Ethiopia. In this village, extension of the grid is not yet practical. As the current international trend in rural electrification is to utilize renewable energy resources; solar, wind, biomass, and micro hydro power systems can be seen as alternatives. Therefore, the target of this paper is to investigate the viability of a micro hydro, Photo Voltaic (PV) and Diesel Generator-battery hybrid power system options to come up with the best techno-economic and optimum configuration for supplying electricity to this village. The study was performed by an assessment of the predicted village energy demand, the available renewable energy resources, and then using the software called HOMER. The best hybrid system type was described and the optimization of the system configuration was also done. Furthermore, through the simulation of different configuration of the supply system, the optimal mini-grid hybrid system design was established to combine hydro, solar PV, battery energy storage and diesel generator. This system demonstrated to be more reliable in operation, and the most cost-effective for the required level of service. The role of energy storage in system operation also demonstrated to offer additional operational advantages in-terms of reliability and cost savings. Overall, the design results show that the majority of energy obtained from hydropower, which accounts 79%, the PV module covers 20%, and diesel generator is only 1% of the total load consumption. The obtained hybrid system is cost competitive with $\$$0.133/kWh, which is somewhat good to satisfy the community needs. However, this is more than current energy price in Ethiopia which $\$$0.06/kWh. If due-merit given to the electricity deficiency of the country, it would play major role in improvement of life quality of community living in rural areas. From environmental standpoint, the renewable fraction of the project is 99%, which shows the system is environmentally friendly. Finally, this study identified that off grid hybrid micro hydro-PV-DG-battery bank energy system is cost effective and environmentally friendly in delivering power for rural areas far from the grid. Moreover, the study provides valuable information to the government and Non-government organization (NGO) about the renewable energy potential of the country for a rural electrification project in Ethiopia.

    Abstract The aim of this study is to analyze various ways to increase the performance of Thermoelectric (TEG) by using Computational Fluid Dynamics (CFD) techniques. For this study a three-dimensional model of TEG is developed using design modeling software SOLIDWORKS and the developed geometry is exported to CFD package which is ANSYS-FLUENT for further analysis. Mass flow rate of exhaust gas is 0.279 kg/s at a temperature of 800 K and mass flow rate of the coolant is 0.26Kg/s at a temperature 350 K are taken as boundary conditions. For this analysis various parameters are investigated such as heat exchanger material, inclination and exit gap of heat deflector and use of baffles. The effect of heat exchanger material on the performance of TEG is investigated. For this investigation pure copper, pure aluminum, aluminum alloy and low-carbon steel are chosen as heat exchanger material. Results show that pure copper has given better performance than others with 184.98 K of temperature difference. To study the effect of exit gap between heat deflector and exhaust pipe on TEG performance, exit gap is varied from 10 mm to 15 mm with an increment of 2.5 mm. The inclination angle of heat deflector is varied from 1° to 3.5° with an increment of 0.5°. Results show that 2°inclination angle of deflector with 10 mm exit gap has given better performance than other inclinations and exit gaps. The influence of baffles on TEG performance is also studied. Introducing a baffle in inclined position directs the flow direction of exhaust gas effectively to achieve better heat distribution. Finally, it can be concluded TEG has good performance with copper material as heat exchanger material, 2° inclination angle of deflector and 10 mm exit gap between heat deflector to the exhaust pipe.

    AbstractCement-stabilized rammed earth, recognized as a sustainable and cost-effective alternative in the construction industry, is gaining traction. This research investigates its potential as an affordable and durable walling material in Addis Ababa, Ethiopia, and compares it with other prevalent walling products. The study evaluates red clay soil’s physical and mechanical characteristics, both pre and post-cement stabilization. Laboratory tests conducted using soil samples from Addis Ababa demonstrate the viability of cement-stabilized rammed earth. Increasing cement content enhances strength and erosion resistance, making it a cost-effective solution for addressing regional housing challenges. This study assessed the effect of cement content at 0%, 5%, 10%, and 15%. Results show that compressive strength increases as the cement content increases; the compressive strength of cement stabilized rammed earth is 1.766 MPa, 2.85 MPa, 4.79Mpa and 7.61 MPa for 0%, 5%, 10%, and 15% cement content respectively. The cement stabilized rammed earth durability test for 10% and 15% cement content against rainfall erosion show no penetration where 117.5 mm and 1 mm penetration depth for 0% and 5% cement content; the findings underscore increased cement content enhancing the material’s resistance to rainfall erosion.

    Sustaining crop production and productivity in sub-Saharan Africa requires the availability and use of quality seed of improved varieties by smallholder farmers. The private sector has been considered as the best way to sustain seed supply and crop productivity. Unfortunately, the private sector’s share in the seed production and delivery in sub-Saharan Africa countries has not been very substantial for decades. As a consequence, farmer access to quality seed of recently released varieties remains very low. This manuscript analyzes the experiences of informal seed producers who graduated to formal private seed enterprises to understand the effectiveness of the support they receive to become viable seed ventures. We used comparative research methods to analyze the qualitative and quantitative data collected to understand the underlying mechanisms. The findings showed that the analyzed seed enterprises started with as little as about USD 300 and have already multiplied over tenfold their initial capital. They benefited from a wide variety of supports, e.g., quality seed production, marketing, partnerships, and value chain development trainings and infrastructures, from extension workers, research centers, national and international NGOs, and the other private seed enterprise operators like large public seed enterprises and agro-dealers. The seed enterprises are producing pre-basic, basic, and certified seed of cereals and self-pollinated legume crops delivered directly to farmers, institutional markets, and agro-dealers. The seed production data have been increasing for the past three years with an area expanding from about 30 ha to over 150 ha per year for chickpea. The seed production and delivery practices being employed are smallholder farmer-based practices that are environmentally friendly. For sustainable and reliable seed production and delivery systems in sub-Saharan Africa, a bold step is needed whereby the informal seed production entities are nurtured and upgraded into formal certified seed production ventures that deliver social and economic benefits to the promotors and the communities.

    Ordinary Portland cement (OPC) is the primary binder of concrete, accounting for approximately 5% to 7% of greenhouse gas (GHG) and carbon dioxide (CO2) emissions with an annual production rate of more than 4 billion tons. It is critical to reduce the carbon footprint of concrete without sacrificing its performance. To this end, this study focuses on the use of water hyacinth ash (WHA) as a pozzolanic binder in the production of concrete as a partial replacement for cement. Four mixes are designed to achieve C-25-grade concrete with varying proportions of cement replacement with WHA of 0%, 5%, 10%, and 15% of the cement weight. Extensive experiments are performed to examine the workability, strength, durability, and microstructure of concrete specimens. The test results confirm that incorporating WHA in concrete improved its workability, strength, and durability. The optimal results are obtained at the maximum OPC replacement level, with 10% WHA. The use of WHA as a partial replacement for cement greatly reduces the energy required for cement production and preserves natural resources. More research is needed to use WHA on a large scale to achieve greater sustainability in the concrete industry.

    Abstract Analysis of performance of fuel cell is carried out by considering non-fluorinated electrolyte and variety of potential electrodes. The study spans low temperature regions and carried out MD investigation of transport of ions in a novel PEM fuel cell (PEMFC), which is composed of electrodes and SPEEK as a non-fluorinated electrolyte. Typical values of ion conductivity σ near room temperature are σ = 8.5 × 10−2 S cm−1 when Pt is used as electrode, σ = 26 × 10−2 S cm−1 when Pd3Ag is used as electrode, and σ = 0.34 × 10−2 S cm−1 when Pd is used as electrode. Thus, this study reveals a twofold implications. Firstly, the choice of electrolyte affects whether the traditional Pt electrode remains to be superior for the overall fuel cell performance. Secondly, using SPEEK electrolyte has a potential to yield a closely matching ion conductivity with the one obtained from the costly Nafion electrolyte.

    This work is a climatological evaluation of terrestrial water storage anomalies (TWSAs), which act as driving forces for sustainable development, in one of the most populous countries of the world. The objective of this work is to evaluate RL06 mascon data from the GRACE and GRACE-FO satellite missions over India to explore seasonal and interannual changes in terrestrial water storage, encompassing an area of ~3.29 million km2 with 285 grid points, from 2002 through to 2020. Several statistical tests are performed to check the homogeneity (i.e., Pettitt’s test, the BRT, the SNHT, and the VNRT). Most of the homogeneous data are found in winter, pre-monsoon, and post-monsoon, approximately above 42% to 47%, and the least are found in monsoons and annual with only 33%, at a 95% significance level. According to Pettitt’s test, the majority of the breakpoints are present in 2014 for winter, 2012 for pre-monsoon, 2011 for monsoons and post-monsoon, and 2008 as well as 2011 for annual. Furthermore, to detect trends and magnitudes we employed the nonparametric MK test, the MMK test, Sen’s slope estimator, and the parametric SLR test. According to the MK and MMK tests, the most significant negative and positive trends indicate the chances of droughts and floods, respectively. The Indo–Gangetic region shows the highest declination. According to Sen’s slope and the SLR test, the most declining magnitude is found in Delhi, Panjab, Uttrakhand, the northern part of Rajasthan, and Uttar Pradesh. Based on our findings, the average declining rate of yearly terrestrial water storage data from the MK, MMK, and SLR tests is −0.0075 m (−0.75 cm/year) from 2002 to 2020. Koppen–Geiger climate zones are also used to depict the seasonal and interannual descriptive statistics of TWSA trends. Interestingly, the annual means of arid desert cold (−0.1788 cm/year) and tropical savanna (−0.1936 cm/year) have the smallest declining trends when compared to other climatic zones. Northern Indian regions’ temperate dry winter, hot/warm summer, and dry arid steppe hot regions show the maximum declining future trend. This study could be useful in planning and managing water resources, agriculture, and the long-term growth of the country by using an intelligent water delivery system.

    Le changement climatique et la variabilité ont été détectés en Éthiopie. Les petits exploitants et les agriculteurs de subsistance, les éleveurs et les ménages tributaires des forêts sont les plus touchés par les risques liés au climat. Ils doivent avoir une perception du changement climatique afin d'y répondre en élaborant des stratégies d'adaptation et/ou d'adaptation. Les perceptions locales et les stratégies d'adaptation fournissent une base cruciale pour les mesures communautaires d'adaptation au changement climatique. Cette étude a été spécifiquement conçue pour (1) évaluer la perception et les connaissances des ménages en matière de changement et/ou de variabilité climatique, et (2) établir les changements observés dans les paramètres climatiques avec les perceptions de la communauté et les anomalies climatiques. La méthode d'échantillonnage aléatoire stratifié intentionnel a été utilisée pour recueillir des informations auprès de 355 ménages de l'échantillon pour des entretiens individuels complétés par des discussions de groupe et des entretiens avec des informateurs clés. L'analyse des données climatiques observées et satellitaires pour le district d'étude a montré que les températures maximales et minimales moyennes pour la période 1983–2014 ont augmenté de 0,047 et 0,028 °C/an, respectivement. Cependant, les précipitations totales ont diminué de 10,16 mm par an. En saison, les précipitations ont diminué de 2,198, 4,541, 1,814 et 1,608 mm par an pour les saisons éthiopienne d'été, de printemps, d'automne et d'hiver, respectivement. De même, la température maximale moyenne de la zone d'étude avait montré un accroissement de 0,035, 0,049, 0,044 et 0,065 °C par an pour les saisons de printemps, d'hiver, d'automne et d'été, respectivement. La variation climatique observée a été confirmée par la perception des gens. Considérant que ce qui existait avant il y a 30 ans était normal, une augmentation de la température, une augmentation de la fréquence des sécheresses, une diminution des précipitations totales, le caractère erratique de sa distribution et le retard de son apparition avaient été perçus par 88, 70, 97, 80 et 94% des répondants, respectivement, à l'heure actuelle-2015. La déforestation en tant que facteur occasionnel du changement et de la variabilité climatiques avait été perçue par 99,7 % des répondants. Cela avait également été confirmé par des études scientifiques car il émet du dioxyde de carbone et est le principal moteur du changement et de la variabilité climatiques. Les connaissances autochtones, y compris les prévisions climatiques, ont été utilisées par les gens pour mettre en œuvre leurs activités agricoles quotidiennes. Par conséquent, la science devrait être intégrée à la perception et aux connaissances autochtones des personnes pour trouver une solution concrète aux impacts du changement climatique et de la variabilité sur les moyens de subsistance humains. Se ha detectado cambio climático y variabilidad en Etiopía. Los pequeños agricultores y agricultores de subsistencia, los pastores y los hogares dependientes de los bosques son los más afectados por los peligros relacionados con el clima. Tienen que tener percepción del cambio climático para poder responder a él a través de la elaboración de estrategias de afrontamiento y/o adaptación. Las percepciones locales y las estrategias de afrontamiento proporcionan una base crucial para las medidas de adaptación al cambio climático basadas en la comunidad. Este estudio fue diseñado específicamente para (1) evaluar la percepción y el conocimiento de los hogares sobre el cambio climático y/o la variabilidad, y (2) establecer los cambios observados en los parámetros climáticos con las percepciones de la comunidad y las anomalías climáticas. El método de muestreo aleatorio estratificado se ha utilizado para recopilar información de 355 hogares de muestra para entrevistas individuales complementadas por discusiones grupales y entrevistas con informantes clave. El análisis de los datos climáticos observados y satelitales para el distrito de estudio mostró que la temperatura media máxima y mínima para el período 1983–2014 ha aumentado en 0.047 y 0.028 ° C/año, respectivamente. Sin embargo, la precipitación total ha disminuido en 10,16 mm por año. Estacionalmente, las precipitaciones han disminuido en 2,198, 4,541, 1,814 y 1,608 mm anuales para las temporadas etíopes de verano, primavera, otoño e invierno, respectivamente. Del mismo modo, la temperatura máxima media del área de estudio había mostrado un incremento de 0.035, 0.049, 0.044 y 0.065 °C por año para las temporadas de primavera, invierno, otoño y verano, respectivamente. La variación climática observada ha sido confirmada por la percepción de las personas. Teniendo en cuenta lo que habían sido las situaciones existentes antes de hace 30 años como normales, un aumento de la temperatura, un aumento de la frecuencia de la sequía, una disminución de la precipitación total, el carácter errático de su distribución y la tardanza de su inicio habían sido percibidos por el 88, 70, 97, 80 y 94% de los encuestados, respectivamente, en el momento actual-2015. La deforestación como factor casual del cambio climático y la variabilidad había sido percibida por el 99,7% de los encuestados. Esto también había sido confirmado por estudios científicos, ya que emite dióxido de carbono y es el principal impulsor del cambio climático y la variabilidad. Los conocimientos indígenas, incluidas las predicciones climáticas, han sido utilizados por las personas para implementar sus actividades agrícolas cotidianas. Por lo tanto, la ciencia debe integrarse con la percepción y el conocimiento indígena de las personas para encontrar soluciones concretas para el cambio climático y los impactos de la variabilidad en los medios de vida humanos. Climate change and variability has been detected in Ethiopia. Smallholder and subsistence farmers, pastoralists and forest-dependent households are the most hit by climate-related hazards. They have to have perception of climate change in order to respond it through making coping and/or adaptation strategies. Local perceptions and coping strategies provide a crucial foundation for community-based climate change adaptation measures. This study was specifically designed to (1) assess households' perception and knowledge in climate change and/or variability, and (2) establish the observed changes in climate parameters with community perceptions and climate anomalies. Purposive stratified random sampling method has been used to gather information from 355 sample households for individual interviews supplemented by group discussion and key informants interviews. The analysis of observed and satellite climate data for the study district showed that mean maximum and minimum temperature for the period 1983–2014 has increased by 0.047 and 0.028 °C/year, respectively. However, the total rainfall has declined by 10.16 mm per annum. Seasonally, the rainfall has declined by 2.198, 4.541, 1.814 and 1.608 mm per annum for Ethiopian summer, spring, autumn and winter seasons, respectively. Similarly, the mean maximum temperature of the study area had showed an increment of 0.035, 0.049, 0.044 and 0.065 °C per year for spring, winter, autumn and summer seasons, respectively. The observed climate variation has been confirmed by people's perception. Considering what had been the existed situations before 30 years ago as normal, an increase in temperature, an increase in drought frequency, a decrease in total rainfall, erratic nature of its distribution and the tardiness of its onset had been perceived by 88, 70, 97, 80 and 94% of the respondents, respectively, at current time—2015. Deforestation as a casual factor of climate change and variability had been perceived by 99.7% of the respondents. This had been also confirmed by scientific studies as it emits carbon dioxide and is the main driver of climate change and variability. Indigenous knowledge, including climate predictions, has been used by people to implement their day-to-day agricultural activities. Therefore, science should be integrated with the perception and indigenous knowledge of people to come up with concrete solution for climate change and variability impacts on human livelihoods. تم الكشف عن تغير المناخ وتقلبه في إثيوبيا. صغار المزارعين ومزارعي الكفاف والرعاة والأسر التي تعتمد على الغابات هم الأكثر تضررًا من المخاطر المتعلقة بالمناخ. يجب أن يكون لديهم تصور لتغير المناخ من أجل الاستجابة له من خلال وضع استراتيجيات للتكيف و/أو التكيف. توفر التصورات المحلية واستراتيجيات التكيف أساسًا حاسمًا لتدابير التكيف مع تغير المناخ المجتمعية. تم تصميم هذه الدراسة خصيصًا من أجل (1) تقييم تصور الأسر ومعرفتها بتغير المناخ و/أو تقلبه، و (2) تحديد التغيرات الملحوظة في المعلمات المناخية مع تصورات المجتمع والشذوذ المناخي. تم استخدام طريقة أخذ العينات العشوائية الطبقية الهادفة لجمع المعلومات من 355 أسرة من العينة لإجراء مقابلات فردية تكملها مناقشة جماعية ومقابلات مع المخبرين الرئيسيين. أظهر تحليل البيانات المناخية المرصودة والأقمار الصناعية لمنطقة الدراسة أن متوسط درجة الحرارة القصوى والدنيا للفترة 1983–2014 قد زاد بمقدار 0.047 و 0.028 درجة مئوية/سنة على التوالي. ومع ذلك، انخفض إجمالي هطول الأمطار بمقدار 10.16 مم سنويًا. انخفض هطول الأمطار موسميًا بمقدار 2.198 و 4.541 و 1.814 و 1.608 ملم سنويًا لفصول الصيف والربيع والخريف والشتاء الإثيوبية على التوالي. وبالمثل، أظهر متوسط درجة الحرارة القصوى لمنطقة الدراسة زيادة قدرها 0.035 و 0.049 و 0.044 و 0.065 درجة مئوية سنويًا لفصول الربيع والشتاء والخريف والصيف، على التوالي. تم تأكيد التباين المناخي الملحوظ من خلال تصور الناس. بالنظر إلى الحالات التي كانت موجودة قبل 30 عامًا على أنها طبيعية، فإن زيادة في درجة الحرارة، وزيادة في تواتر الجفاف، وانخفاض في إجمالي هطول الأمطار، والطبيعة غير المنتظمة لتوزيعها وتأخر ظهورها قد أدركها 88 و 70 و 97 و 80 و 94 ٪ من المستجيبين، على التوالي، في الوقت الحالي 2015. اعتبر 99.7 ٪ من المستجيبين إزالة الغابات كعامل عرضي لتغير المناخ وتقلبه. وقد أكدت الدراسات العلمية ذلك أيضًا لأنه ينبعث منه ثاني أكسيد الكربون وهو المحرك الرئيسي لتغير المناخ وتقلبه. استخدم الناس معارف السكان الأصليين، بما في ذلك التنبؤات المناخية، لتنفيذ أنشطتهم الزراعية اليومية. لذلك، يجب دمج العلم مع التصور والمعارف الأصلية للناس للتوصل إلى حل ملموس لتغير المناخ وآثار التقلبات على سبل عيش الإنسان.

    Le changement climatique et la variabilité ont été détectés en Éthiopie. Les petits exploitants et les agriculteurs de subsistance, les éleveurs et les ménages tributaires des forêts sont les plus touchés par les risques liés au climat. Ils doivent avoir une perception du changement climatique afin d'y répondre en élaborant des stratégies d'adaptation et/ou d'adaptation. Les perceptions locales et les stratégies d'adaptation fournissent une base cruciale pour les mesures communautaires d'adaptation au changement climatique. Cette étude a été spécifiquement conçue pour (1) évaluer la perception et les connaissances des ménages en matière de changement et/ou de variabilité climatique, et (2) établir les changements observés dans les paramètres climatiques avec les perceptions de la communauté et les anomalies climatiques. La méthode d'échantillonnage aléatoire stratifié intentionnel a été utilisée pour recueillir des informations auprès de 355 ménages de l'échantillon pour des entretiens individuels complétés par des discussions de groupe et des entretiens avec des informateurs clés. L'analyse des données climatiques observées et satellitaires pour le district d'étude a montré que les températures maximales et minimales moyennes pour la période 1983–2014 ont augmenté de 0,047 et 0,028 °C/an, respectivement. Cependant, les précipitations totales ont diminué de 10,16 mm par an. En saison, les précipitations ont diminué de 2,198, 4,541, 1,814 et 1,608 mm par an pour les saisons éthiopienne d'été, de printemps, d'automne et d'hiver, respectivement. De même, la température maximale moyenne de la zone d'étude avait montré un accroissement de 0,035, 0,049, 0,044 et 0,065 °C par an pour les saisons de printemps, d'hiver, d'automne et d'été, respectivement. La variation climatique observée a été confirmée par la perception des gens. Considérant que ce qui existait avant il y a 30 ans était normal, une augmentation de la température, une augmentation de la fréquence des sécheresses, une diminution des précipitations totales, le caractère erratique de sa distribution et le retard de son apparition avaient été perçus par 88, 70, 97, 80 et 94% des répondants, respectivement, à l'heure actuelle-2015. La déforestation en tant que facteur occasionnel du changement et de la variabilité climatiques avait été perçue par 99,7 % des répondants. Cela avait également été confirmé par des études scientifiques car il émet du dioxyde de carbone et est le principal moteur du changement et de la variabilité climatiques. Les connaissances autochtones, y compris les prévisions climatiques, ont été utilisées par les gens pour mettre en œuvre leurs activités agricoles quotidiennes.

    To meet sustainable development goals and address concerns on climate change, much of the world's energy demand is expected to be delivered from clean alternative energy sources. Small-scale wind turbines have proven to be applicable for off-grid electrification. The objective of this study is to present the details on the design and manufacture of a 1 kW wind turbine blade for specified conditions. Blade element moment theory is adopted in the design of the geometry of the blade. Accordingly, the aerodynamic analysis on NACA 64A410 airfoil resulted in a blade radius of 1.95m, an overall twist angle of 31°, and a gradually tapering chord length of 0.062m at the root and 0.247m at the tip of the blade. Then, the wind turbine blades are manufactured from fiberglass (mat350g), resin, catalyst, and gelcoat. Experimental results reveal the wind turbine blades started producing power at a cut-in wind speed of 3m/s. The maximum power achieved during the testing process was 900W at a hub wind velocity of 9m/s. This is lower than the expected 1000W theoretical power output due to not perfect workmanship in the manufacture of the wind turbine blades. This study will help in building local manufacturing facilities and enhance rural electrification through off-grid technologies.

    To meet sustainable development goals and address concerns on climate change, much of the world's energy demand is expected to be delivered from clean alternative energy sources. Small-scale wind turbines have proven to be applicable for off-grid electrification. The objective of this study is to present the details on the design and manufacture of a 1 kW wind turbine blade for specified conditions. Blade element moment theory is adopted in the design of the geometry of the blade. Accordingly, the aerodynamic analysis on NACA 64A410 airfoil resulted in a blade radius of 1.95m, an overall twist angle of 31°, and a gradually tapering chord length of 0.062m at the root and 0.247m at the tip of the blade. Then, the wind turbine blades are manufactured from fiberglass (mat350g), resin, catalyst, and gelcoat. Experimental results reveal the wind turbine blades started producing power at a cut-in wind speed of 3m/s. The maximum power achieved during the testing process was 900W at a hub wind velocity of 9m/s. This is lower than the expected 1000W theoretical power output due to not perfect workmanship in the manufacture of the wind turbine blades. This study will help in building local manufacturing facilities and enhance rural electrification through off-grid technologies.

    Le secteur agricole reste la principale source de moyens de subsistance des communautés rurales en Éthiopie, mais le défi du changement climatique continue de constituer une grave menace pour son développement. Cette étude a examiné les facteurs affectant les décisions des petits exploitants agricoles d'adopter des options d'adaptation au changement climatique dans l'ouest de l'Éthiopie à l'aide de données recueillies auprès de 400 ménages échantillonnés. L'indice de satisfaction des précipitations et le modèle logit multinomial ont été utilisés pour analyser l'exposition des agriculteurs à la variabilité climatique et aux facteurs qui façonnent les stratégies d'adaptation des agriculteurs. Les résultats de l'étude ont montré que la majorité des agriculteurs sont fortement exposés au changement climatique à la fois en termes de pluviométrie variable et d'augmentation de la température. En réponse, pour s'adapter à l'impact du changement climatique, les agriculteurs participaient aux pratiques agronomiques, à la diversification des moyens de subsistance, à la conservation des sols et de l'eau et à l'irrigation à petite échelle en tant qu'options d'adaptation dominantes. Il est également observé que l'adoption de pratiques agronomiques a été considérablement influencée par le capital social, l'expérience des mauvaises récoltes et l'accès à l'alerte précoce. Il a été constaté que le genre du ménage, l'éducation et la propriété du bétail avaient une relation négative avec la diversification des moyens de subsistance. L'étude a également révélé que les mesures de conservation des sols et de l'eau sont affectées positivement par la perception de l'augmentation de la température, l'exposition aux systèmes d'alerte précoce et la plus grande taille des terres cultivées. En outre, l'adoption de l'irrigation à petite échelle a été considérablement influencée par l'accès au crédit, le capital social et le statut éducatif des chefs de famille. Par conséquent, le résultat implique que les programmes et les politiques conçus pour freiner les calamités du changement climatique devraient mettre l'accent sur la création de systèmes d'alerte précoce efficaces pour sensibiliser les agriculteurs, atteindre les agriculteurs avec des institutions de microfinance efficaces et encourager les liens des agriculteurs avec de nombreuses coopératives sociales. El sector agrícola sigue siendo la principal fuente de sustento para las comunidades rurales de Etiopía, pero el desafío del cambio climático sigue representando una grave amenaza para su desarrollo. Este estudio investigó los factores que afectan las decisiones de los pequeños agricultores de adoptar opciones de adaptación al cambio climático en el oeste de Etiopía utilizando datos recopilados de 400 hogares muestreados. El Índice de Satisfacción de Lluvias y el Modelo Logit Multinomial se utilizaron para analizar la exposición de los agricultores a la variabilidad climática y los factores que dan forma a las estrategias de adaptación de los agricultores. Los hallazgos del estudio mostraron que la mayoría de los agricultores están experimentando una alta exposición al cambio climático tanto en términos de precipitaciones variables como de aumento de la temperatura. En respuesta, para adaptarse al impacto del cambio climático, los agricultores estaban participando en las prácticas agronómicas, la diversificación de los medios de vida, el ahorro de suelo y agua y el riego a pequeña escala como las opciones de adaptación dominantes. También se observa que la adopción de prácticas agronómicas se vio afectada significativamente por el capital social, la experiencia de fracaso de los cultivos y el acceso a la alerta temprana. Se encontró que el género del hogar, la educación y la propiedad del ganado tenían una relación negativa con la diversificación de los medios de vida. El estudio reveló además que las medidas de conservación del suelo y el agua se ven afectadas positivamente por la percepción del aumento de la temperatura, la exposición a sistemas de alerta temprana y el mayor tamaño de las tierras cultivadas. Además, la adopción del riego a pequeña escala se vio influenciada significativamente por el acceso al crédito, el capital social y el estado educativo de los jefes de hogar. En consecuencia, el resultado implica que los programas y políticas diseñados para frenar las calamidades del cambio climático deben enfatizar la creación de sistemas efectivos de alerta temprana para aumentar la conciencia de los agricultores, llegar a los agricultores con instituciones de microfinanzas efectivas y fomentar los lazos de los agricultores con muchas cooperativas sociales. The agricultural sector remains the main source of livelihood for rural communities in Ethiopia, but the challenge of changing climate continues to pose a serious threat to its development. This study investigated factors affecting smallholder farmers' decisions to adopt adaptation options to climate change in West Ethiopia using data collected from 400 sampled households. The Rainfall Satisfaction Index and Multinomial Logit Model were used to analyze farmers' exposure to climate variability and factors that shape farmers' adaptation strategies. The findings of the study showed that the majority of farmers are experiencing high exposure to climate change both in terms of variable rainfall and rising temperature. In response, to adapt to the impact of climate change farmers were participating in agronomic practices, livelihood diversification, soil and water conservation, and small-scale irrigation as the dominant adaptation options. It is also observed that adopting agronomic practices was significantly impacted by social capital, crop failure experience, and access to early warning. Gender of the household, education, and livestock ownership were found to have a negative relationship with livelihood diversification. The study further revealed that soil and water conservation measures are positively affected by perception of temperature increment, exposure to early warning systems, and larger size of cultivated land. In addition, the adoption of small-scale irrigation was significantly influenced by access to credit, social capital, and the educational status of household heads. Consequently, the result implies that programs and policies designed to curb the calamities of climate change should emphasize creating effective early warning systems to increase farmer awareness, reach farmers with effective microfinance institutions, and encourage farmers' ties to many social cooperatives. لا يزال القطاع الزراعي المصدر الرئيسي لسبل عيش المجتمعات الريفية في إثيوبيا، لكن التحدي المتمثل في تغير المناخ لا يزال يشكل تهديدًا خطيرًا لتنميته. بحثت هذه الدراسة في العوامل التي تؤثر على قرارات صغار المزارعين باعتماد خيارات التكيف مع تغير المناخ في غرب إثيوبيا باستخدام البيانات التي تم جمعها من 400 أسرة تم أخذ عينات منها. تم استخدام مؤشر الرضا عن هطول الأمطار ونموذج المنطق متعدد الحدود لتحليل تعرض المزارعين لتقلبات المناخ والعوامل التي تشكل المزارعين واستراتيجيات التكيف. أظهرت نتائج الدراسة أن غالبية المزارعين يعانون من ارتفاع التعرض لتغير المناخ من حيث هطول الأمطار المتغير وارتفاع درجة الحرارة. واستجابة لذلك، وللتكيف مع تأثير تغير المناخ، كان المزارعون يشاركون في الممارسات الزراعية، وتنويع سبل العيش، والحفاظ على التربة والمياه، والري على نطاق صغير كخيارات التكيف السائدة. كما لوحظ أن اعتماد الممارسات الزراعية تأثر بشكل كبير برأس المال الاجتماعي، وتجربة فشل المحاصيل، والوصول إلى الإنذار المبكر. وجد أن جنس الأسرة والتعليم وملكية الماشية لها علاقة سلبية بتنويع سبل العيش. وكشفت الدراسة كذلك أن تدابير الحفاظ على التربة والمياه تتأثر بشكل إيجابي بتصور زيادة درجة الحرارة، والتعرض لأنظمة الإنذار المبكر، وحجم أكبر من الأراضي المزروعة. بالإضافة إلى ذلك، تأثر اعتماد الري على نطاق صغير بشكل كبير بالوصول إلى الائتمان ورأس المال الاجتماعي والوضع التعليمي لرب الأسرة. وبالتالي، فإن النتيجة تعني أن البرامج والسياسات المصممة للحد من كوارث تغير المناخ يجب أن تركز على إنشاء أنظمة فعالة للإنذار المبكر لزيادة وعي المزارعين، والوصول إلى المزارعين بمؤسسات فعالة للتمويل الأصغر، وتشجيع روابط المزارعين بالعديد من التعاونيات الاجتماعية.

    Electricity supply in Ethiopia is extremely antiquated. Most of the remote rural areas of Ethiopia are not yet electrified. Electrifying these remote areas by extending grid system is difficult and costly. Melkey Hera village is one of a rural community situated in western Ethiopia. In this village, extension of the grid is not yet practical. As the current international trend in rural electrification is to utilize renewable energy resources; solar, wind, biomass, and micro hydro power systems can be seen as alternatives. Therefore, the target of this paper is to investigate the viability of a micro hydro, Photo Voltaic (PV) and Diesel Generator-battery hybrid power system options to come up with the best techno-economic and optimum configuration for supplying electricity to this village. The study was performed by an assessment of the predicted village energy demand, the available renewable energy resources, and then using the software called HOMER. The best hybrid system type was described and the optimization of the system configuration was also done. Furthermore, through the simulation of different configuration of the supply system, the optimal mini-grid hybrid system design was established to combine hydro, solar PV, battery energy storage and diesel generator. This system demonstrated to be more reliable in operation, and the most cost-effective for the required level of service. The role of energy storage in system operation also demonstrated to offer additional operational advantages in-terms of reliability and cost savings. Overall, the design results show that the majority of energy obtained from hydropower, which accounts 79%, the PV module covers 20%, and diesel generator is only 1% of the total load consumption. The obtained hybrid system is cost competitive with $\$$0.133/kWh, which is somewhat good to satisfy the community needs. However, this is more than current energy price in Ethiopia which $\$$0.06/kWh. If due-merit given to the electricity deficiency of the country, it would play major role in improvement of life quality of community living in rural areas. From environmental standpoint, the renewable fraction of the project is 99%, which shows the system is environmentally friendly. Finally, this study identified that off grid hybrid micro hydro-PV-DG-battery bank energy system is cost effective and environmentally friendly in delivering power for rural areas far from the grid. Moreover, the study provides valuable information to the government and Non-government organization (NGO) about the renewable energy potential of the country for a rural electrification project in Ethiopia.

    Electricity supply in Ethiopia is extremely antiquated. Most of the remote rural areas of Ethiopia are not yet electrified. Electrifying these remote areas by extending grid system is difficult and costly. Melkey Hera village is one of a rural community situated in western Ethiopia. In this village, extension of the grid is not yet practical. As the current international trend in rural electrification is to utilize renewable energy resources; solar, wind, biomass, and micro hydro power systems can be seen as alternatives. Therefore, the target of this paper is to investigate the viability of a micro hydro, Photo Voltaic (PV) and Diesel Generator-battery hybrid power system options to come up with the best techno-economic and optimum configuration for supplying electricity to this village. The study was performed by an assessment of the predicted village energy demand, the available renewable energy resources, and then using the software called HOMER. The best hybrid system type was described and the optimization of the system configuration was also done. Furthermore, through the simulation of different configuration of the supply system, the optimal mini-grid hybrid system design was established to combine hydro, solar PV, battery energy storage and diesel generator. This system demonstrated to be more reliable in operation, and the most cost-effective for the required level of service. The role of energy storage in system operation also demonstrated to offer additional operational advantages in-terms of reliability and cost savings. Overall, the design results show that the majority of energy obtained from hydropower, which accounts 79%, the PV module covers 20%, and diesel generator is only 1% of the total load consumption. The obtained hybrid system is cost competitive with $\$$0.133/kWh, which is somewhat good to satisfy the community needs. However, this is more than current energy price in Ethiopia which $\$$0.06/kWh. If due-merit given to the electricity deficiency of the country, it would play major role in improvement of life quality of community living in rural areas. From environmental standpoint, the renewable fraction of the project is 99%, which shows the system is environmentally friendly. Finally, this study identified that off grid hybrid micro hydro-PV-DG-battery bank energy system is cost effective and environmentally friendly in delivering power for rural areas far from the grid. Moreover, the study provides valuable information to the government and Non-government organization (NGO) about the renewable energy potential of the country for a rural electrification project in Ethiopia.

    Abstract The aim of this study is to analyze various ways to increase the performance of Thermoelectric (TEG) by using Computational Fluid Dynamics (CFD) techniques. For this study a three-dimensional model of TEG is developed using design modeling software SOLIDWORKS and the developed geometry is exported to CFD package which is ANSYS-FLUENT for further analysis. Mass flow rate of exhaust gas is 0.279 kg/s at a temperature of 800 K and mass flow rate of the coolant is 0.26Kg/s at a temperature 350 K are taken as boundary conditions. For this analysis various parameters are investigated such as heat exchanger material, inclination and exit gap of heat deflector and use of baffles. The effect of heat exchanger material on the performance of TEG is investigated. For this investigation pure copper, pure aluminum, aluminum alloy and low-carbon steel are chosen as heat exchanger material. Results show that pure copper has given better performance than others with 184.98 K of temperature difference. To study the effect of exit gap between heat deflector and exhaust pipe on TEG performance, exit gap is varied from 10 mm to 15 mm with an increment of 2.5 mm. The inclination angle of heat deflector is varied from 1° to 3.5° with an increment of 0.5°. Results show that 2°inclination angle of deflector with 10 mm exit gap has given better performance than other inclinations and exit gaps. The influence of baffles on TEG performance is also studied. Introducing a baffle in inclined position directs the flow direction of exhaust gas effectively to achieve better heat distribution. Finally, it can be concluded TEG has good performance with copper material as heat exchanger material, 2° inclination angle of deflector and 10 mm exit gap between heat deflector to the exhaust pipe.

    AbstractCement-stabilized rammed earth, recognized as a sustainable and cost-effective alternative in the construction industry, is gaining traction. This research investigates its potential as an affordable and durable walling material in Addis Ababa, Ethiopia, and compares it with other prevalent walling products. The study evaluates red clay soil’s physical and mechanical characteristics, both pre and post-cement stabilization. Laboratory tests conducted using soil samples from Addis Ababa demonstrate the viability of cement-stabilized rammed earth. Increasing cement content enhances strength and erosion resistance, making it a cost-effective solution for addressing regional housing challenges. This study assessed the effect of cement content at 0%, 5%, 10%, and 15%. Results show that compressive strength increases as the cement content increases; the compressive strength of cement stabilized rammed earth is 1.766 MPa, 2.85 MPa, 4.79Mpa and 7.61 MPa for 0%, 5%, 10%, and 15% cement content respectively. The cement stabilized rammed earth durability test for 10% and 15% cement content against rainfall erosion show no penetration where 117.5 mm and 1 mm penetration depth for 0% and 5% cement content; the findings underscore increased cement content enhancing the material’s resistance to rainfall erosion.

    Sustaining crop production and productivity in sub-Saharan Africa requires the availability and use of quality seed of improved varieties by smallholder farmers. The private sector has been considered as the best way to sustain seed supply and crop productivity. Unfortunately, the private sector’s share in the seed production and delivery in sub-Saharan Africa countries has not been very substantial for decades. As a consequence, farmer access to quality seed of recently released varieties remains very low. This manuscript analyzes the experiences of informal seed producers who graduated to formal private seed enterprises to understand the effectiveness of the support they receive to become viable seed ventures. We used comparative research methods to analyze the qualitative and quantitative data collected to understand the underlying mechanisms. The findings showed that the analyzed seed enterprises started with as little as about USD 300 and have already multiplied over tenfold their initial capital. They benefited from a wide variety of supports, e.g., quality seed production, marketing, partnerships, and value chain development trainings and infrastructures, from extension workers, research centers, national and international NGOs, and the other private seed enterprise operators like large public seed enterprises and agro-dealers. The seed enterprises are producing pre-basic, basic, and certified seed of cereals and self-pollinated legume crops delivered directly to farmers, institutional markets, and agro-dealers. The seed production data have been increasing for the past three years with an area expanding from about 30 ha to over 150 ha per year for chickpea. The seed production and delivery practices being employed are smallholder farmer-based practices that are environmentally friendly. For sustainable and reliable seed production and delivery systems in sub-Saharan Africa, a bold step is needed whereby the informal seed production entities are nurtured and upgraded into formal certified seed production ventures that deliver social and economic benefits to the promotors and the communities.

    Sustaining crop production and productivity in sub-Saharan Africa requires the availability and use of quality seed of improved varieties by smallholder farmers. The private sector has been considered as the best way to sustain seed supply and crop productivity. Unfortunately, the private sector’s share in the seed production and delivery in sub-Saharan Africa countries has not been very substantial for decades. As a consequence, farmer access to quality seed of recently released varieties remains very low. This manuscript analyzes the experiences of informal seed producers who graduated to formal private seed enterprises to understand the effectiveness of the support they receive to become viable seed ventures. We used comparative research methods to analyze the qualitative and quantitative data collected to understand the underlying mechanisms. The findings showed that the analyzed seed enterprises started with as little as about USD 300 and have already multiplied over tenfold their initial capital. They benefited from a wide variety of supports, e.g., quality seed production, marketing, partnerships, and value chain development trainings and infrastructures, from extension workers, research centers, national and international NGOs, and the other private seed enterprise operators like large public seed enterprises and agro-dealers. The seed enterprises are producing pre-basic, basic, and certified seed of cereals and self-pollinated legume crops delivered directly to farmers, institutional markets, and agro-dealers. The seed production data have been increasing for the past three years with an area expanding from about 30 ha to over 150 ha per year for chickpea. The seed production and delivery practices being employed are smallholder farmer-based practices that are environmentally friendly. For sustainable and reliable seed production and delivery systems in sub-Saharan Africa, a bold step is needed whereby the informal seed production entities are nurtured and upgraded into formal certified seed production ventures that deliver social and economic benefits to the promotors and the communities.

    Ordinary Portland cement (OPC) is the primary binder of concrete, accounting for approximately 5% to 7% of greenhouse gas (GHG) and carbon dioxide (CO2) emissions with an annual production rate of more than 4 billion tons. It is critical to reduce the carbon footprint of concrete without sacrificing its performance. To this end, this study focuses on the use of water hyacinth ash (WHA) as a pozzolanic binder in the production of concrete as a partial replacement for cement. Four mixes are designed to achieve C-25-grade concrete with varying proportions of cement replacement with WHA of 0%, 5%, 10%, and 15% of the cement weight. Extensive experiments are performed to examine the workability, strength, durability, and microstructure of concrete specimens. The test results confirm that incorporating WHA in concrete improved its workability, strength, and durability. The optimal results are obtained at the maximum OPC replacement level, with 10% WHA. The use of WHA as a partial replacement for cement greatly reduces the energy required for cement production and preserves natural resources. More research is needed to use WHA on a large scale to achieve greater sustainability in the concrete industry.

    Abstract Analysis of performance of fuel cell is carried out by considering non-fluorinated electrolyte and variety of potential electrodes. The study spans low temperature regions and carried out MD investigation of transport of ions in a novel PEM fuel cell (PEMFC), which is composed of electrodes and SPEEK as a non-fluorinated electrolyte. Typical values of ion conductivity σ near room temperature are σ = 8.5 × 10−2 S cm−1 when Pt is used as electrode, σ = 26 × 10−2 S cm−1 when Pd3Ag is used as electrode, and σ = 0.34 × 10−2 S cm−1 when Pd is used as electrode. Thus, this study reveals a twofold implications. Firstly, the choice of electrolyte affects whether the traditional Pt electrode remains to be superior for the overall fuel cell performance. Secondly, using SPEEK electrolyte has a potential to yield a closely matching ion conductivity with the one obtained from the costly Nafion electrolyte.

    Abstract Analysis of performance of fuel cell is carried out by considering non-fluorinated electrolyte and variety of potential electrodes. The study spans low temperature regions and carried out MD investigation of transport of ions in a novel PEM fuel cell (PEMFC), which is composed of electrodes and SPEEK as a non-fluorinated electrolyte. Typical values of ion conductivity σ near room temperature are σ = 8.5 × 10−2 S cm−1 when Pt is used as electrode, σ = 26 × 10−2 S cm−1 when Pd3Ag is used as electrode, and σ = 0.34 × 10−2 S cm−1 when Pd is used as electrode. Thus, this study reveals a twofold implications. Firstly, the choice of electrolyte affects whether the traditional Pt electrode remains to be superior for the overall fuel cell performance. Secondly, using SPEEK electrolyte has a potential to yield a closely matching ion conductivity with the one obtained from the costly Nafion electrolyte.

    This work is a climatological evaluation of terrestrial water storage anomalies (TWSAs), which act as driving forces for sustainable development, in one of the most populous countries of the world. The objective of this work is to evaluate RL06 mascon data from the GRACE and GRACE-FO satellite missions over India to explore seasonal and interannual changes in terrestrial water storage, encompassing an area of ~3.29 million km2 with 285 grid points, from 2002 through to 2020. Several statistical tests are performed to check the homogeneity (i.e., Pettitt’s test, the BRT, the SNHT, and the VNRT). Most of the homogeneous data are found in winter, pre-monsoon, and post-monsoon, approximately above 42% to 47%, and the least are found in monsoons and annual with only 33%, at a 95% significance level. According to Pettitt’s test, the majority of the breakpoints are present in 2014 for winter, 2012 for pre-monsoon, 2011 for monsoons and post-monsoon, and 2008 as well as 2011 for annual. Furthermore, to detect trends and magnitudes we employed the nonparametric MK test, the MMK test, Sen’s slope estimator, and the parametric SLR test. According to the MK and MMK tests, the most significant negative and positive trends indicate the chances of droughts and floods, respectively. The Indo–Gangetic region shows the highest declination. According to Sen’s slope and the SLR test, the most declining magnitude is found in Delhi, Panjab, Uttrakhand, the northern part of Rajasthan, and Uttar Pradesh. Based on our findings, the average declining rate of yearly terrestrial water storage data from the MK, MMK, and SLR tests is −0.0075 m (−0.75 cm/year) from 2002 to 2020. Koppen–Geiger climate zones are also used to depict the seasonal and interannual descriptive statistics of TWSA trends. Interestingly, the annual means of arid desert cold (−0.1788 cm/year) and tropical savanna (−0.1936 cm/year) have the smallest declining trends when compared to other climatic zones. Northern Indian regions’ temperate dry winter, hot/warm summer, and dry arid steppe hot regions show the maximum declining future trend. This study could be useful in planning and managing water resources, agriculture, and the long-term growth of the country by using an intelligent water delivery system.
