Natural environment and land use in the Chad Basin, NE-Nigeria : preliminary results of an interdisciplinary research

  • The objective of this paper is to combine the environmental conception of the Kanuri with detailed findings of pedological and botanical field investigations. Interpretation of multitemporal satellite data and aerial photographs should provide land cover and land use information for an extended area. The area of investigation was outlined within the transitional zone from the clay plains to the sandy areas by interpretation of satellite images. The presented subset of a SPOT-XS-satellite image shows part of the Marte Local Government Area with its capital Old Marte in the north-eastern part of the image. The darker colours represent the clay plains while the lighter parts are related to the sandy areas. Almost half of the research area is covered by clay but all settlements are located on the slightly elevated sandy areas. Within these sandy areas different gray shades demonstrate the pattern of the rainy season farming area. Differences in colour within the clay plains are mainly due to variances in soil, water content and vegetation cover. In the north-eastern part of the image irrigation channels of the South Chad Irrigation Project are visible. The main attention, especially of the pedological and botanical research, was directed towards the south-western part of the subset in the vicinity of the villages of Wulwa, Dura, Kajere and Ngubdori.
