Change detection of the Upper Orashi forest wetland of Nigeria, using geospatial analysis

  • Wetland is an essential ecosystem that provides numerous goods and services such as tourism and recreation, water purification, and groundwater recharge. It also acts as a carbon sink, which means that it is an essential asset in reducing the level of greenhouse gases in the environment. Despite the value, wetlands are disappearing at a fast rate, however, the need to ascertain the state of Upper Orsahi forest reserve wetland with respect to wetlands change. To ascertain the net and transition change detection in the wetland area of the Upper Orashi Forest Wetland, land cover classification change was performed using Geographic Information Systems and Remote Sensing methods, particularly the supervised classification of land cover data for 2002, 2013, and 2019. The land cover was classified into three classes: wetland, thick vegetation and light vegetation. The result shows a significant degradation of the Upper Orashi forest reserve wetlands within the study period.

The land cover was classified into three classes: wetland, thick vegetation and light vegetation. The result shows a significant degradation of the Upper Orashi forest reserve wetlands within the study period. The data from the questionnaire is to know which sector and activities in the area result in wetland loss. The result shows that industrial sector is the major driver of wetland loss in the area, while the activities include; building of industries, installation of oil and gas facilities, and agriculture. This means that the available laws used to manage Nigeria's wetlands are ineffective. However, there is an urgent need to enact a new regulation for effective/sustainable management of wetlands in the country.show moreshow less
