  Remote Sensing has been used to study the characteristic properties of the surface of the earth due to the advantages of its broad area of observation and periodicity. This study presents a study carried out to map the ecological risk zones of Kogi State in Central Nigeria by integrating the analytical tools of Geographic Information System (GS) with Remote Sensing (RS). Landsat ETM + image data of 2005 was used for the identification and mapping of ecologically fragile areas in the state. Seasonally flooded areas, areas susceptible to soil erosion and gully development and other vulnerable areas were identified and demarcated. The study revealed that about 2636 km2 or 21.42% of the territory of the state is flooded annually and also prone to soil erosion. The impact of this on the subsistence agricultural practice in the state is quite enormous. The study underlined the importance of creating the necessary mechanism by the state and Federal Government Agencies to monitor, check and control these problems.

  The number of natural and human-made disaster is on the rise worldwide. Over the last few months, Nigeria has witnessed an astronomic increase in rate of bombing and other fire outbreak. Recently, a Dana plane crashed in Lagos, Nigeria killing about 152 passengers. Most of these passengers died as a result of the fire outbreak. The rates of fire outbreak have increased tremendously in Onitsha metropolis. This may be attributed to illegal electricity connection and lack of quick response by the fire service department to stop the fire at an early stage. Government has lost a lot of money in payment of compensation to victim of fire outbreak. The emotional distress on the victim of this incidence is unquantifiable and in some cases result to loss of human lives. Government in its effort to tackle this problem has invigorated the state fire service department to be able to tackle this challenge by providing new equipment for them. But how effective has this effort been able to solve this problem. GIS offers itself as an effective tool to manage this problem since it can graphically display features on the ground and be able to perform query on them. The analytical capabilities of GIS can detect the possible shortest route as well as model the housing pattern and location of important features, thereby providing a quick response to fire outbreak. This study discusses the application of GIS to effectively manage fire disaster in Onitsha metropolis. It explores the great potential of GIS in managing fire disasters through sample queries. The research recommends immediate increase in the number of fire stations in Onitsha.
