Biophysical Mapping and Land Use Attributes of Kano Ecosystems, North-western Nigeria

Abstract

The study examines the terrestrial ecosystems component in Kano, Nigeria. The study employed direct digitization using latest Google Earth Image (version 10.3) and National Space Research Development Agency (NASRDA) land use map of the state. Simple descriptive statistics was also used to evaluate units of ecosystems indentified. The results revealed 16 ecosystems of land units within Kano terrestrial ecosystems. Mapping of the study area also revealed anthropogenic cultivation ecosystem Major category of 18,542km2 representing 89% while aquatic ecosystem covered a total 506 km2 with altitude elevation of 480above the sea level (a.s.l.). Shelterbelts and wind breaks were 458 - 498 a.s.l. with >100 approximate number of patches. Results were discussed and concluded as Kano ecosystem land use attributes revealed an interdependence of units with major terrestrial and minor aquatic ecosystems with the serious anthropogenic interferences which result in systemic loss of valuable units of ecosystems, ecosystem services and biodiversity components. Therefore, government should embark on mass awareness campaign on proper land use and sustainable environmental policies framework in the state should be enacted.
