Urban expansion in Uyo Urban Area was analyzed using aerial photographs taken from 1969-2001 which use was complemented with the Quick bird satellite imagery for 2004. The objectives of this study were to evaluate the urban expansion that had taken place in Uyo Urban Area over the periods of the study and to assess its influence on agricultural lands. The geographical information system (GIS) technology and field studies were applied to carry out this research. The analysis showed that Agricultural lands continually dropped in land area during the period while the built-up lands constantly rose. The built-up lands increased by 40.
This study measured and analyzed deforestation in Uyo and examined the possible effects of the deforestation on the Environment. When and where have forest lands changed in Uyo from 1969 -2004? Aerial photographs taken from 1969 -2001 which use was complemented with the Quick bird satellite imagery for 2004 were applied. The objectives of this study were to: interpret and digitize remote sensing data for Uyo for the periods 1969, 1978, 1988, 2001 and 2004; evaluate the deforestation changes that had taken place in Uyo over the periods of the study and to assess the effect of deforestation on the Uyo environment. Along the remote sensing technology, the geographical information system (GIS) technology was applied to carry out this research. Field studies were also carried out to arrive at appropriate results. Forestlands continually dropped in land area during the period while industrial lands, institutional, residential and transportation lands recorded increases in land areas. Reclassifying the land uses into built-up and forest lands revealed that the built-up lands constantly rose while the forest lands kept dropping.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
