Description Decline in forest structure and quality prompted the study, essentially to examine the spatial effects ofdeforestation on the edaphic components of the environment of Kogi East, Kogi State, Nigeria. Itfocused specifically on soil and vegetation, while it assessed the implication of the destructiveinterference by humans with the natural ecosystem based on the results of preliminary investigation.Results showed thatt in many parts of the study area, substantial hectares of the forest landscape hadbeen primarily logged and abandoned. Over a 100,000 hectares of vegetation cover was lostannually, most of which were deliberately removed to make way for agriculture, mineral exploitation,urbanization and expansion of settlements, among others. Reforestation efforts reportedlyreplenished only 25,000 hectares. In order to investigate this trend, Classified Satellite Imageries ofKogi state covering 1990-2010 were acquired to assess land use information. The process involvesland use mapping and the detection of changes using remote sensing and GIS techniques. Additionalland use information were acquired through field observation and theoretical survey. Whencategorized and analyzed, the four main land use components (soil, vegetation, water and the builtenvironment) covered in this study demonstrated significant effects relationship with deforestation.Implicatively, the results of this analysis shows that there had been significant increases in the effectsof these land uses on the forest landscape thus resulting in forest depletion, soil degradation andobserved destruction of the ecosystem. It was thus concluded that land use practices in the study areamust be carried out within the limits of forestry standard for a sustainable forest management.
