The researcher's work integrates a comprehensive exploration of land use dynamics and ecosystem responses using advanced remote sensing technologies. This integrated approach allows for a detailed analysis of various ecological challenges such as water cycle variations, fire impact on wetlands, soil erosion, and Cocoa land transformations. The integration of GIS and machine learning tools enhances our understanding of these complex systems across different regions in Ghana, addressing critical issues like water cycle dynamics, fire risks, and soil erosion. Additionally, the study examines cocoa land transformation impacts on tree distribution and richness, cocoa farmers' livelihoods, urban development challenges faced by cocoa farmers, and cocoa mining's ecological implications. Furthermore, it highlights cocoa transformations' effects on vegetation structure and their impact on forest ecosystems in the Keta Lagoon basin. This research underscores the importance of sustainable agriculture and land management strategies to support food security and environmental balance.
Faculty Biography
Dr. George Ashiagbor is a senior lecturer at the Faculty of Renewable Natural Resources of the Kwame Nkrumah University of Science and Technology. He is a GIS and Remote Sensing Analyst, and his research interests revolve around using Remote Sensing and GIS tools to study landscape-level changes and the interactions between humans and the environment. He is particularly interested in the assessment of deforestation, forest monitoring, landscape ecology, conservation, land use/cover change, natural resource management, environmental modelling, and environmental systems, which serve as a basis for landscape planning.Dr. Ashiagbor has been actively involved in developing methodologies for accurately mapping Ghana's landscape using Remote Sensing approaches. He was the Remote Sensing technical lead for the Forest 2020 Ghana project, a collaboration between the Forestry Commission of Ghana and Ecometrica, a UK Space Agency-funded project to develop approaches for segregating cocoa from forest. Additionally, Dr. Ashiagbor has led several land use land cover mapping and analysis activities in Ghana, with a primary focus on mapping and analysing commodities (cocoa, oil palm, and rubber) driven deforestation. With his extensive research conducted in the cocoa-forest mosaic landscape of Ghana, he has made significant contributions to the discussions around the European Union's Deforestation Regulation (EUDR). Dr. Ashiagbor has conducted research on a range of topics, including land use and cover change, forest monitoring, deforestation assessment, landscape ecology, conservation, environmental modelling, and natural resource management. He has been the Principal Investigator for four granted projects and Remote Sensing lead for three other funded projects. His expertise and contributions to the field are widely recognised and respected. Dr. Ashiagbor is currently collaborating with the CSIR-Soil Research Institute in Ghana to develop a framework supported by remote-sensing technology. This framework aims to incentivize site-specific agronomic management of smallholder cocoa farms. The project, named FRAME-Cocoa, is funded by the African Plant Nutrition Institute (APNI).
