Abstract Details

2023, Master of Science (MS), Ohio University, Geography (Arts and Sciences).
This thesis aimed to understand the complex interactions between land-use changes and agricultural production to inform decision-making and maximize crop yields. The research used advanced tools and techniques, including GIS, remote sensing, and spatial modeling, to analyze changes in land cover classes over time. The results showed a significant shift in land cover, with cropland increasing from 43.15% in 2010 to 55.03% in 2016, while grassland decreased from 48.38% in 2010 to 36.69% in 2016. The thesis also explored the impact of environmental factors on maize yields in three Nigerian states, finding that temperature and precipitation was the most sensitive factor influencing yields, and that land cover changes had a moderate influence. The study highlights the importance of using advanced tools and techniques to analyze land use and cover changes and their impact on agricultural production. The findings provide valuable insights for remote sensing and GIS practitioners interested in monitoring land cover and land use changes for natural land preservation, urbanization, agricultural land expansion and sustainability, as well as farmland loss. Furthermore, this thesis demonstrates the importance of considering environmental factors such as temperature, normalized vegetation index, and precipitation alongside land cover changes to better understand the impact of different factors on crop yields. It is recommending the use of both multiple regression models and spatial geographical models to gain a better understanding of how different land cover changes affect crop yields, with the latter providing better results based on AIC and 𝑅2.
