 programmes in communities. The study focuses on the use of Remote Sensing and Geographic Information System technology to propose an effective assessment of the vulnerability of Kubwa town to flooding and the capacity for implementing a DRR programme in the area. Satellite imageries for three periods: 1987, 2001 and 2006 were used for an overall assessment to produce a contemporary land use maps. Comparative analyses of the old land use map, the master plan and the derived land use map shows that there has been consistent changes in the original land use compared to the current, evidenced in the increase of areas allotted for residential purposes (20.54% to 75.6%). Buffering analysis was carried out to determine areas that fall within the floodplain. Digital Terrain Modelling (DTM) and slope analysis were used to re-classify the area into different levels of vulnerability. The analyses showed that the central part of Kubwa, which is the most populated area, is most affected by flood incidences due to soil sealing resulting to infiltration. Other features of this area are encroachment on the flood plains, clogging of the drains and lack of land use planning. The study therefore recommends the need for improved land use planning, enforcement of standards and codes, Community Education/ participation, among others.&picture=http://www.aascit.org/aascit/decorators/img/journal/924.jpg)

Disaster occurrences are on the increase all over the world and large numbers of people are constantly exposed to the risk associated with these disasters including flooding. Urban areas, especially in developing countries, are highly vulnerable with increasing threat of flood; there is therefore need for an assessment of flood vulnerability and capacity for implementing disaster risk reduction (DRR) programmes in communities. The study focuses on the use of Remote Sensing and Geographic Information System technology to propose an effective assessment of the vulnerability of Kubwa town to flooding and the capacity for implementing a DRR programme in the area. Satellite imageries for three periods: 1987, 2001 and 2006 were used for an overall assessment to produce a contemporary land use maps.
