Item Forested landscape dynamics in Saki-East local government area of Oyo State, Nigeria(Forests and Forest Products Society, 2021) Alo, A. A.; Onilude, Q. AThe prime objective of this study is to apply Remote Sensing and GIS technology in examining the trend and pattern of land cover changes observed between forested and non-forested landscapes in Saki east LGA of Oyo State, Nigeria. This was done for the purposes of determining changes in the vegetation cover for a period of 27 year. Satellite Imageries were obtained from Global Land Cover Facility (GLCF) and GLOVIS. Landsat Thematic Mapper of 1992, 2001, 2010 and Operational Land Imager of 2019 were obtained at 30m resolution. The Image analysis was done and created using ArcGis 10.5 (ESRI, Redland, CA). Satellite imagery was classified into two major categories, Forested landscape and Non-forested landscape. Results from satellite imageries also showed that forested landscape decreased from a total land area of 139,510 ha (84.53%) in 1992 to 102,480 ha (62.09%) in 2019. The amount of land area lost by forested landscape is being added up by the non-forested landscape. 2.53% of forested landscape was lost to non-forested between 1992-2001, with 18.05% and 1.86% lost between 2001-2010 and 2010-2019 respectively. However, percent change per year in lost of forested landscape observed was 0.28%, 2.01% and 0.21% between 1992-2001, 2001-2010 and 2010-2019 respectively. It was concluded that changes observed in forested landscape was due to deforestation to provide raw materials for wood industries, and space for agriculture and building of house for the increasing population in the area. The implications of deforestation for biodiversity and climate change have been highlighted.
