GIS-based identification of potential irrigable areas in Ejiba, Nigeria

None

Abstract

Rivers are essential natural resources for transportation, recreation, irrigation, fishing, and water and electricity provision. Geographic Information Systems (GIS) have revolutionized the analysis and interpretation of geographical data, making them indispensable tools in various fields. A field survey identified 10 existing irrigation sites along the River Kampe in 2023. The built-up area covered 1.43 km², accounting for 0.62 % of the total land area, while bare land and water bodies covered 81.69 km² and 1.22 km², respectively. The vegetation cover class recorded the highest area at 122.76 Km², while agriculture land covered 24.91 km². It was concluded that the most suitable, more suitable, suitable, less suitable, and unsuitable land uses accounted for 24.67 %, 22.62 %, 19.30 %, 13.74 %, and 19.68 % of the area respectively. The map created using this platform can serve as a rough guide for choosing appropriate sites for surface irrigation in the area.
