THE EFFECTS OF LAND USE ON THE GREENHOUSE GADES EMISSION IN OKITIPUPA AND IRELE SOUTHWEST, NIGERIA.

This study investigates the impact of various land use practices on greenhouse gas (GHG) emissions in Okitipupa and Irele Local Government Areas, located in Southwest Nigeria. The region, characterized by diverse land use patterns including agriculture, urbanization, forestry, and wetlands, presents a unique case for understanding how different land uses contribute to GHG emissions. Given the global concern over climate change and the role of GHGs in exacerbating this phenomenon, it is crucial to analyze localized emission sources and propose sustainable land management strategies. The research employs a multi-faceted approach, combining field surveys, remote sensing, geographic information system (GIS) techniques, and GHG emission modeling to assess the emissions associated with distinct land use categories. Data were collected from various land use types such as farmland, forest area, residential area, oil palm plantations and , with a focus on identifying the specific activities within these areas that contribute to GHG emissions, including deforestation, agricultural practices, and urban development. The findings indicate significant differences in GHG emissions across the various land use types, with deforestation and intensive agricultural practices identified as the leading contributors. These activities not only release carbon dioxide (CO2) but also methane (CH4) and nitrous oxide (N2O), which are potent GHGs. In contrast, natural forests and wetlands showed a capacity for carbon sequestration, highlighting the importance of preserving these ecosystems as a strategy for mitigating GHG emissions.The study underscores the need for integrated land use planning and management to reduce GHG emissions in the region. It recommends policy interventions that promote sustainable agricultural practices, reforestation, and the protection of natural landscapes. Additionally, the research suggests the adoption of renewable energy sources and improved waste management in urban areas to further curb emissions. In conclusion, this research provides critical insights into the relationship between land use and GHG emissions in Okitipupa and Irele Local Government Areas. The study’s findings emphasize the urgent need for targeted policies and practices that promote sustainable land use, balancing development needs with environmental protection. By implementing these recommendations, it is possible to significantly reduce GHG emissions, contributing to global efforts to combat climate change and ensuring the long-term environmental sustainability of the region. The study also xii highlights the importance of continuous monitoring and assessment of land use impacts on GHG emissions to adapt strategies in response to changing environmental conditions.
