Abstract: Sericulture is the backbone of alternative income generation to local communities. Sericulture is control deforestation, maintain climate change, control greenhouse gas effects and global warming, control erosion, flood and sedimentation down the slope. The ultimate aim of sericulture is established to combat desertification. Open job opportunity to youth, women, men, HIV/AIDS infested people. Generally, create job opportunity without categories age for all age groups, except under age and over aged people. These are through silkworm rearing and establishment of mulberry plantation for silkworm food. This project was entitled with: establishment of sericulture technology in Oda Bultum university for training of trainees and food insecure areas of west Harareghe zonal watersheds: the case of Oda Bultum university, west Harareghe zone, Oromia regional national state Ethiopia. The objectives include: The students will be able to acquire knowledge, skill and attitude practically in the field of sericulture technology; to produce the higher and the most competent manpower in the field of sericulture technology; to make the University the exemplary for others’ Universities, colleges, and institutions in the field of sericulture technology and to create a means of alternative income source for the university; to create job opportunities for the jobless youth by recruiting in the department; to provide training, introduced and implemented sericulture in the rural areas of west Harareghe zone and to make the university silkworm seed center or grange center of silkworm to west Harareghe zone and even if eastern Showa and eastern Harareghe zone and even though including the Qafar and Somali region in the long run. Questionnaires will be develop in closed and semi-closed; then that distributed randomly to Woreda, zone, and kebele, NGOS and governmental organization to select the most suitable areas to establish the sericulture technology. Thus, the collected feedback shall be analyzed and based on that decided the where needs priority. Mentoring of the project treds should conducted at certain intervals weekly or monthly. Evolution of the project shall be carry out at the middle or at the end of the project.

Abstract: This article assessed the historical climate attributes and the future projections for the Lemo district of south central Ethiopia based on the observed and the projected climate variables of the Meher season. An observation of rainfall, temperature, and down welling short wave radiation for the period 1991–2020 and climate projection data from the CanESM2 RCM for the period of 2021–2100 under the RCP4.5 and RCP8.5 were used. Model Bias Correction Method of capturing historical rainfall and temperature data for that specific area of study then correcting the bias found between the RCM data and observed station data. In our case, we have applied a scientific software called CMhyd (Climate Model data for hydrologic modeling) to extract the net CDF (Network Common Data Form) model data obtained from RCMs. Statistical tests and variability measuring indexes applied for analysis. Results showed insignificantly increasing trends of rainfall and temperature over the Lemo district during 1990 to 2020. And also the projections by 2021 to 2050 (near term), 2050 to 2080 (mid-term) as well as 2081 to 2100(end-term) indicate an increase in temperature compared to the 1991-2005 of baseline periods. Whereas high variability of rainfall amount, onset and cessation changes are expected to be happened in the future. This finding shows increasing trend of variability in rainfall and temperature indicating the risks of climate change impact. Therefore identifying relevant agricultural, environmental and social adaptation strategies are desirable.

Abstract: Life and politics, once marked by the “will of heaven” in determining the fate of half the world (Communist and Capitalist), have come to an end along with the conclusion of the Cold War. A new, shared hope has emerged to achieve the goal of shaping global politics. Life is no longer separated from the calculations and mechanisms of politics but shares the same desire: to pursue a better life. Life and politics are no longer detached. The effort to achieve a better life is carried out through various global and regional economic collaborations and free markets. However, the benefits cannot be equally enjoyed; each actor seeks to maximize their own gains from opportunities to increase profits. Strict regulations have thus become a constant process of interest-driven change, aligned with new interests, pushing the emergence of institutions embedded in political authority (the rulers, government, parliament, bureaucracy) to oversee market territories in order to standardize political and economic resources within the forces of production, as part of the effort to achieve continuous profit in the midst of free trade-through processes of overproduction and consumption. This article is a philosophical concept using normative research methods that engage in depth with various theoretical sources including Descartes, Foucault, Hegel, Weber and Bourdieu. How exactly is the consequence of “Politics”. That the consequence of politics is to direct human action, from all aspects of life. Every aspect of life whether in the fields of power, economy, culture and defense aims to persuasively anticipate themselves in the sovereignty of taking lives for maximum gain - where no one can act better without making others worse off. Each assumes the position of the zone of profit extraction and, at the same time, the consumer as a dumping ground - instead of politics leading in practice to a situation of letting die rather than being said to be a killer. Thus, what manifests in life today is a trajectory of physical and mental labor, which distorts the line between politics and death (quietus politic).

Abstract: This researches the dose–response efficacy of two lignocellulosic coagulants (sawdust and rice husk) in comparison with ferric chloride for textile and tannery wastewaters treatment. The jar tests were conducted using six different doses of the coagulants (0, 2, 4, 6, 8, and 10 grams per 250 milliliters of wastewater) following a completely randomized factorial design, with each test repeated three times to ensure reliable results. The efficiency of the coagulants was evaluated based on several types of key parameters: pH, electrical conductivity (EC), turbidity, total suspended solids (TSS), total dissolved solids (TDS), hardness and extracts concentration into chloride, phosphate and to cadmium had been measured. The data demonstrated the influence of the coagulant type and dose on almost all parameters, as well as multiple wastewater × coagulant interaction effects (p ≤ 0.05). In general, sawdust proved to be better than rice husk and ferric chloride when applied for all physico-chemical properties and pollutant removal excepting pH adjustment, the turbidity, reduction in solids and cadmium removal^^. The maximum doses, especially 10 g, gave the highest enhancements for both wastewater kinds. The results demonstrate that lignocellulosic coagulants, especially sawdust, are feasible and economical substitutes for the conventional inorganic metal salts as primary treatment agents to textile and tannery industries which are confronted with increasing environmental demand. Importantly, the research indicates possible application of agricultural waste by-products by large water treatment industries.

Abstract: Rainfall data is vital for agricultural planning, water resource management, and climate research in areas like Oromia, Ethiopia, where agriculture supports a large part of the population. However, ground-based observations are often limited and inconsistent. This study assesses how well satellite-derived rainfall estimates match ground observations in Oromia. In the analysis of the ENACT, CHIRPS, and TAMSAT satellite products against ground-based rainfall data, all three exhibited a consistent value sequence but did not accurately reflect the observed declining rainfall trend from 1470 mm to 30 mm. While they showed correlation in pattern, each product indicated an increasing trend that contradicted ground measurements, suggesting issues in remote precipitation sensing due to varied algorithms and data sources. CHIRPS demonstrated a perfect Probability of Detection (POD) and the correlation value (CORR, 0.717), making it preferable despite a higher Mean Absolute Error (MAE, 55.678) compared to ENACT (48.195), which had a smaller Root Mean Square Error (RMSE, 88.753). ENACT (CORR, 0.736) displayed the strongest correlation with ground truth observations in Oromia, proving its reliability for temporal and geographical rainfall patterns, highlighting the need for ongoing validation against ground truth for improved precipitation estimates crucial for hydrological and agricultural purposes. These results imply that satellite products can be reliable alternatives in areas like Oromia, where data is limited, although regional differences in topography and rainfall patterns affect accuracy.
