In the heart of Southwest Ethiopia, the city of Mizan Aman is undergoing rapid transformation, and a groundbreaking study is shedding light on the environmental impacts of its urbanization. Led by Addis Bikis from the Department of Surveying Engineering at Mizan-Tepi University, the research, published in Scientific Reports, delves into how the city’s growth is altering land use and land cover, with significant implications for the energy sector and beyond.
Mizan Aman, known for its nine-month rainy season and hot climate, is experiencing an alarming rate of urban settlement expansion. This growth, driven by the demand for housing, infrastructure, and manufacturing, is coming at a cost to the city’s natural environment. “Urban settlement were increased at alarming rate due to land demand for housing, infrastructure and manufacturing,” Bikis noted, highlighting the urgent need for sustainable urban planning.
The study, which spanned three decades from 1992 to 2022, utilized geographic information systems (GIS) and remote sensing techniques to analyze land use and land cover changes. The findings are stark: dense forests, moderate forests, sparse forests, and open shrublands have significantly decreased by 68.96%, 24.60%, 31.36%, and 8.28% respectively. This deforestation, driven by urban functions such as timber production, construction materials, and firewood, is not just an environmental concern but also a critical issue for the energy sector.
Deforestation can lead to increased land surface temperatures, a phenomenon that can exacerbate the urban heat island effect. This, in turn, can increase energy demands for cooling, putting a strain on power grids and driving up energy costs. Moreover, the loss of forests can reduce carbon sequestration, further contributing to climate change and its associated impacts on energy infrastructure.
Bikis’ research underscores the need for urban planners to prioritize sustainable environmental management and integrated land use zoning. Active community involvement is also crucial in protecting against unsustainable changes in land use and land cover. “Urban planners must prioritize sustainable environmental management, integrated land use zoning, and active community involvement,” Bikis emphasized, calling for a holistic approach to urban development.
The study also points to future research directions, suggesting the use of multi-source remote sensing and high-resolution imaging to differentiate land cover more effectively. The integration of CO2 estimation techniques could also provide deeper insights into the environmental changes associated with urbanization.
For the energy sector, these findings highlight the importance of considering land use and land cover changes in energy planning and infrastructure development. As cities like Mizan Aman continue to grow, it will be crucial to adopt sustainable practices that mitigate environmental impacts and ensure energy security.
This research is more than just a study of a single city; it’s a call to action for urban planners, policymakers, and energy sector professionals worldwide. As urbanization continues to shape our world, it’s imperative that we learn from studies like Bikis’ and strive for sustainable, environmentally conscious development. The future of our cities, and our planet, depends on it. The study was published in Scientific Reports, a journal that translates to ‘Reports of Science’ in English.
