This project study investigated the land use-land cover (LULC) and NDVI changes in the Jimma zone, Kersa woreda, Ethiopia over a period of 30 years from 1990 to 2020. Four sets of Landsat imageries (i.e., 1990, 2000, 2010, and 2020) were the input The LULC change analysis revealed a continuous decline of forest lands throughout the first (1990-2000), second (2000-2010), and third (2010-2020) study periods by 24.5%, 23.6%, and 21.5%, respectively data from which LULC maps were produced and analyzed using remote sensing and GIS applications. On the contrary, settlement areas increased by 12.7% in the first, 13.9% in the second, and 13.9% in the third period. Agricultural lands also expanded over the study periods by 50.2%, 51.2%, and 52.1%, respectively. The NDVI change analysis revealed a continuous decline of forest lands that NDVI value of (1990-2020), decline from 0.789 high and -0.4 low to 0.559 high and -0.17 low respectively. The overall results of the analysis showed that between the years 1990 and 2020, forest lands, decreased while agricultural lands and settlement areas increased, respectively. Therefore, it is important to prioritize and design strategies for better LULC systems and natural resource conservation for integrated and sustainable development. http://www.iaees.org/publications/journals/piaees/articles/2024-14(4)/spatio-temporal-dynamics.pdf
