Potentials of GIS-based analyses of Ajaokuta -Kaduna-Kano gas pipeline in Nigeria

Abstract. Geographic and Information System (GIS) Potentials and emerging technologies in overcoming topographic challenges during construction of Ajaokuta-Kaduna-Kano (AKK) gas pipeline was reviewed. The increasing utilisation of natural gas in Nigeria require development of more gas pipeline systems to increased supply with the existing gas pipeline infrastructures. Hence, in selecting a route for AKK gas pipeline construction project. This paper report on the effects of topography and probable challenges that may arise as a result of Ajaokuta Kaduna –Kano gas pipeline construction activities and solutions so as to reduce the overall rate of adverse natural gas pipeline incidents and effects on environment. The proposed Ajaokuta-Kaduna-Kano (AKK) gas pipeline is a 614 km-long being developed by the Nigerian National Petroleum Corporation (NNPC) from Ajaokuta to Kano in Nigeria. Gas pipeline routes are defined by the pipeline size(s), terrain, soil erosion, and engineering analysis requirements. Major challenges and impacts of the AKK gas pipeline includes vegetation clearing; hills and contours; loss of biodiversity; loss of farmlands, crops, migration of wildlife, soil erosion, excavation damage and corrosion. GIS Potentials and emerging technologies could address AKK gas pipeline challenges and impact through detection as a higher priority than prevention. These can be addressed through improved technologies by focusing on carrying out topographical study of the area, detection as a higher priority than prevention. Proper selection of gas pipeline routes through GIS could generally reduce potential environmental impacts associated with pipeline construction and typically minimize negative effects on conserving sensitive environments and resources.
