Using Geospatial Information Technology in Natural Resources Management: The Case of Urban Land Management In West Africa

View Article: PubMed Central - PubMed

ABSTRACT

In the past several decades, Lagos Metropolis emerged as one of the fastest urbanizing cities in the West African Sub-region. In the absence of a regular use of geospatial information management systems, limited effort had been made to keep track of changes in the natural environment in the rapidly growing city for policy making in land administration. The ubiquitous energy radiated by the rapid urbanization rate in the area not only created unprecedented consequences by diminishing the quality of the environment and natural resources but it raises serious implications for land management in the region. The factors fuelling the land crisis in the area which are not far fetched consists of socio-economic, ecological and policy elements. To tackle these issues in a mega city, up-to-date knowledge would be required to capture and analyze land information trends. Such an effort will help manage the city's expansion as well as infrastructure development through the right choices in planning and (spatial) designs using the latest tools in geospatial technologies of Geographic Information Systems GIS) and remote sensing. This study investigates the spatial implications of the rapid expansion of metropolitan Lagos for land management using GIS and Remote sensing technology. The result of the research provides a valuable road map that can enable planners contribute to improved land administration necessary for effective management of natural resources.

Mentions: Table 2 and figures 2 and 3 shows the results of the classification for 1984 and 2000 images. From table 2, land area under water declined from the initial estimate of 29,040 hectares (ha) in 1984 to 24,708 in 2000. This represents an overall decrease of 14.91 percent. The size of area covered by vegetation, which include coastal mangrove, forest and grassland areas experienced a significant decline from 180,384 ha in 1984 to 140,568 ha in 2000. While the area of Lagos containing water and vegetation were experiencing a decline, agriculture and settlement was increasing. For example, between 1984 and 2000, agricultural activities increased from 4,615 ha to 9,806 representing an overall change of 112.48 percent. The size of land designated as settlement also showed a change of 159.02 percent in the same time.
