Abstract: The seasonality of meteorology significantly influences the distribution of atmospheric pollution that have harmful effect on human, environment and economy. Similarly, Ethiopia has erratic seasons, this can impact air pollution. Thus, this study focused on intercomparison of PurpleAir PM2.5 measurement at Addis Ababa city. The existing data processed by R software. Accordingly, the finding show that, during the rainy season, PM2.5 levels exhibit a consistent pattern with concentrations peaking in the early night and reaching their lowest at midday. At Black Lion Hospital (BLH), peak concentrations extend to midday due to due to heavy traffic and cross-sectional jams to travel commercial areas. In contrast, during the semi-rainy and dry seasons, PM2.5 levels peak in the early morning and decrease by midday. Hourly variations in PM2.5 concentrations could be influenced by factors such as temperature inversion, wind, relative humidity, and solar intensity, alongside transportation and industrial activities. Analysis reveals that a significant proportion of the seasonal hourly mean trend during the rainy season, vary in between 30 µg/m3 to 50 µg/m3 of the hourly data while 15 µg/m3 to 40 µg/m3 of data in both the semi-rainy and dry seasons also surpass these guidelines. Despite the general reduction in pollution levels due to rain, the rainy season still contributes to elevated PM2.5 concentrations, posing substantial risks to human health, the environment, and development activities. The monthly mean pattern further highlights a peak in PM2.5 concentrations during the rainy season, underscoring the complex dynamics of air quality. This finding emphasizes the need for targeted strategies to manage pollution throughout the year. The finding suggest that, expand air quality monitoring, and reduce traffic emissions, strengthen industrial regulations and increase public awareness. It may relevance for air quality management strategies for local and regional governments.

Abstract: Ethiopia is among the countries vulnerable to the impact of climate change due to its mostly resilient on rain-fed agriculture, but currently started crop production by irrigation even if it is not done in large, and largely rural population. Carbon farming is an emerging agricultural practice focused at mitigating climate change by increasing the carbon sequestration potential of farmlands. Both climate-smart agriculture and carbon farming encloses different approaches such as agroforestry, cover cropping, and application of bio-char and no-till farming, all of which promotes soil carbon sequestration and improves soil health; which help capture carbon dioxide from the atmosphere and store it in soil and vegetation. This system not only mitigates greenhouse gas emission but also fortifies ecosystem resilience through enhancement of soil fertility, water retention and biodiversity. By incorporating carbon farming into worldwide climate action frameworks, agricultural landscapes can evolve from being major sources of greenhouse gases to functioning as net carbon sinks. As scalable strategies to address climate change, carbon farming presents a dual advantage fulfilling the pressing requirements to reduce atmospheric CO2 levels while promoting sustainable agricultural practice and enhancing rural economies. Climate-smart agriculture has emerged as a paradigm shifting approach aimed at improving agricultural productivity, adapting to evolving climatic conditions, and mitigating to the emission of greenhouse gas emissions. This review accentuates the significance of climate-smart agriculture and carbon farming as a crucial strategy for Ethiopia to fulfill its national determined contributions under the Paris agreement, while simultaneously bolstering the resilience of its agricultural system. By scaling up both approaches, Ethiopia can attain a harmonious equilibrium between food security and climate change mitigation; ensuring sustainable development for the rapidly expanding population.
