Virtually every state in Nigeria experiences various kinds of disaster (natural and man-made). Conventional approaches to solving disaster problems have not efficiently addressed the inherent problems in hazard occurrences and management. The use of geographic information systems (GIS) and remote sensing imageries was noted with a view to proffering solution to flood disaster management in Nigeria. Content analysis was applied in arriving at our solution to the flood disaster risk management. Developing countries generally do not have access to remotely sensed imageries on the fly for assessing and monitoring disasters. But the UN has stepped in to alleviate this problem through its cooperating bodies by recommending that developing countries must be helped to have access to remote sensing data. This is being implemented. Nigeria Sat-1 was launched in 2003 to supply fundamental datasets and for monitoring natural occurrences. This satellite has expired. More satellites were launched by Nigeria after the 2003 launch for other purposes. Effort should be intensified to augment the datasets by building databases for our rivers, coastal areas, etc. The databases are required for digital analysis and decision-making on hazard management. Use of GIS and remote sensing techniques is highly recommended. Nigeria is enjoined, as a way of enhancing data available from Nigerian satellites, to utilize the opportunity offered by the UN to have access to remote sensing imageries of pre- and post-disaster areas in the country.
