Impact of climatic variabilities and extreme incidences on the physical environment, public health, and people’s livelihoods in Ethiopia

Introduction

Since the pre-industrial revolution era, climatic hazards such as global warming, El Niño, La Niña, cyclones, droughts, hurricanes, floods, and forest fires have significantly impacted ecosystems, human life, and property due to the Earth’s diverse weather patterns (Aghakouchak et al., 2020). These events have escalated in frequency and intensity, underscoring the global relevance of climate change as one of the most urgent challenges facing humanity today. For instance, Zscheischler et al. (2020) emphasize that rising global temperatures have resulted in increasingly erratic rainfall patterns, while Norris et al. (2016) highlight the continuous melting of ice sheets and glaciers, which are causing fluctuating ocean levels. The effects of these climatic changes have become most apparent through the increased occurrence of extreme weather events such as devastating storms, catastrophic floods, intense heatwave

Abstract

E. coli are frequently isolated food-borne pathogens from meat, milk, and their products. Moreover, there has been a significant rise in the antimicrobial resistance patterns of E. coli O157:H7 to commonly used antibiotics. A cross-sectional study was conducted from October 2019 to July 2021 to estimate prevalence and identify associated factors of E. coli and E. coli O157:H7 and to determine antibiotic resistance pattern of E. coli O157:H7 from foods of bovine origin in Dessie and Kombolcha towns. A total of 384 samples were collected. Systematic and simple random sampling techniques were employed for sampling carcasses and milking cows, respectively. E. coli and E. coli O157:H7 were detected according to recommended bacteriological protocols. E. coli O157:H7 strains were evaluated for in vitro antimicrobial susceptibility using agar disk diffusion method. Both descriptive and inferential statistical techniques were applied to analyze the data. Overall prevalence rates of E. coli and E. coli O157:H7 were 54.7% and 6.5%, respecti

This document provides an overview of major developments in Ethiopia from 1941-1995. It discusses: - The consolidation of imperial power under Haile Selassie I following Italy's defeat, and the agreements he was forced to sign with Britain that restricted Ethiopian sovereignty. - Ethiopia's quest to regain the territories of Eritrea and Ogaden, which were rejected by Britain in favor of their own interests in the region. Eritrea's status was disputed until it was forcibly united with Ethiopia in 1962. - The growing relationship between Ethiopia and the US as Britain's influence declined. Haile Selassie I turned to the US to modernize Ethiopia and consolidate his power.
