Urbanization is a process that always initiates the continual transformation of land from one use to the other. Land transformation is presently being experienced in and around fast growing towns, like Anyigba in Kogi State. This study used Remote sensing and GIS techniques to identify, mark, and measure the extent of the various land uses from the Land use map of 1995 and Nigeriasat 1 imagery of 2006. The study revealed that there have been tremendous transformation in the various land uses, with the built-up area expanding more than other land uses with 398.4%. Gaining 167 ha, 613.45 ha, 159.62 …

This research integrated remote sensing and Geographic Information Systems (GIS) to identified land use/cover types in Lokoja, including their temporal transformation and association with surface temperatures from the LandSat TM and LandSat ETM imageries of 1987 and 2001 respectively. As the built-up area increased in size (2667.6%) so was the surface temperature (6.48oC), vacant land (872%: 9.65oC), cultivated land (104.4%: 1.2oC) and water bodies (64.3%:0.94oC) while vegetation cover increased by 2.44oC while its area extent decreased (316.7%). These changes were responsible for the rise in the mean surface temperature from 38.39oC in 1987 to 42.61oC in 2001, indicating a 4.22oC …

The role of urban agriculture in the food supply of cities and towns, as a complement to rural agriculture is becoming an important issue in a globalizing world economy. The developing countries see it as a way to alleviate urban poverty. Remote sensing and GIS techniques were used to assess areal extent of urban agricultural land in Lokoja. Questionnaires were also used to evaluate the contributions to urban agriculture to food security and income generation among the urban poor in Lokoja. The result revealed that urban agricultural land had increased, thereby implying that urban agriculture is supporting many urban poor …

This study used remote sensing techniques to estimate surface radiant temperature of Lokoja town from LandSat ETM satellite imagery of 2001. The research was conducted in the phases of Pre-fieldwork, fieldwork and post fieldwork. Data generated from the field and satellite imagery were integrated, analysed, interpreted in a GIS environment. The result indicated that built-up area (336.14 K) and vacant land (321.63 K) exhibit the highest surface radiant temperature, while vegetated surfaces (301.23 K), water bodies (303.06 K) and cultivated land (307.56K) recorded the lowest radiant temperature respectively. Specifically, the resulting land surface temperature was 313.06K. Generally, this approach was …

Land Surface Temperature (LST) of Lokoja town were retrieved from LandSat TM imagery of 1987. The NDVI and land emissivity were estimated from visible and near infrared bands, while the effective satellite temperature was estimated from the thermal infrared band. The Qin et al's mono-window algorithm was employed to obtain the land surface temperatures of the different land use/cover types in Lokoja town. The result indicated that vacant land and built-up have the highest LST values of 331.13K and 329.82K, and vegetation, water bodies and cultivated land having the least with 294.03K, 296.76K and 306.06K respectively. The average retrieved LST …

Remote Sensing And Gis Applications In Urban Expansion And Loss Of Vegetation Cover In Kaduna Town, Northern Nigeria, Olarewaju Oluseyi Ifatimehin
Olarewaju Oluseyi Ifatimehin
Anthropogenic drivers such as the urbanization and economic dependence have being a major force shaping various landscapes. Kaduna town is no exception of such landscapes. This study uses remote sensing and GIS techniques with survey to identify the various land uses, their various transformations over the a period of 11 years (1990-2000)and to measure the rate of urban expansion and loss of vegetation cover in the study area. The study revealed that built-up area is expanding at about 167.86 hectares annually vegetation covers declining at a faster rate of 297.5 hectares annually. It also revealed that bare land a component …
