    A System Dynamic Analysis for Cement Production and Carbon Emissions in Ethiopia
    (AAU, 2023-06-01) Shimelis Fikre; Alemu Lambamo (PhD)
    Cement production in Ethiopia is backbone for economic development by constructing large projects such as Grand Ethiopian Renaissance Dam (GERD), Mega Projects, road, etc. Conversely, the concentration of CO2 emissions from cement sector is challenging issue to future climate changes. Over time the demand for cement is increasing for housing and infrastructure development, while the productivity of cement production among the factory is yet poor. Most cement industry in Ethiopia use combustion of imported fossil fuels. However, these leads to high concentration of CO2 emission, productions inefficiency, high cost of operations, loss of productions due to various problem such as shortage of power, spare part, etc. and vulnerability to climate change severity in Ethiopia. This study simulates and develops System Dynamic Model for cement sector to explore endogenous behavior of variables within the model, using Causal Loop Diagram and Stock-Flow Diagram. According to simulation of this study, at end of 2030 the CO2 emission from cement industry is more than double, about 8.92mill. tonsCO2 as compared to 4.37 mill. tonsCO2 in 2022, as well cement production also doubles at the end of 2030 about 16.28 mill. tons. Thus, depict that the carbon emissions proportionally increasing with cement productions. Therefore, the study recommends to utilizes alternative renewable energy resource and modern technological kiln processor to improve their energy efficacy and more productive as well as cope environmental burden of carbon emissions from cement sector of Ethiopia.
