Abstract

The study examined the Geospatial Analysis of Urban Expansion on Wetland Management in Calabar Metropolis: A Case of Edim Otop District, Cross River State. The main objective was to assess the rate of change in urban expansion between the period of 2000 and 2019. A survey research design was adopted to elicit information from the respondents. A total of 355 copies of questionnaire were distributed to the respondent using simple random technique. Data on land use cover change between 2000 and 2019 was gotten from Erdas imagine. Data analysis was carried out using independent sample t test and Pearson correlation statistic. The result proved that in the year 2000 built-up area was 3.12 sqkm and in the year 2019 built-up area was 33.54 sqkm while in the year 2000, wetland covered an area of 11.57 sqkm and in the year 2019, wetland covered an area 9.39 sqkm this showed that there was a drastic change between the year 2000 and 2019 with wetland reducing and urban expansion increasing implying that urban expansion has negative impact on wetland areas. It was also revealed that there is a significant relationship between urban expansion and wetland loss in Edim Axis. Statistical test showed that a Pearson correlation(r) was achieved at 0.650 or 65 percent, hence there is strong positive correlation between urban expansion and wetland loss in Edim Otop axis. Furthermore, the result revealed a significant value p (0.002)< 0.05. Hence, urban expansion has negatively impacted on the wetland leading to its loss in Edim Otop. The study recommends that government should strictly enforce its sustainable urban policies so as to control rapid urbanization to mitigate the impact associate with wetland degradation in Calabar Municipality.
