Promoting Aqua-silviculture in Niger-Delta Region of Nigeria using RS and GIS Technology
Aqua-silviculture (AS) has been considered as one of the most promising options of combining forest conservation with rural development, community empowerment and poverty reduction objectives. But studies have shown that more than 75 % of the coastal area have been degraded by human activities.
Therefore, this paper was aimed at promoting AS in Niger-Delta region of Nigeria using RS and GIS technology. This paper studies five states out of nine states that comprise the Niger-delta region using Remote Sensing (RS) and Geographic information (GIS). NigeriaSat-1 imagery of Akwa Ibom, Bayelsa, Delta, Cross River and River states was imported into ILWIS version 3.1 software installed in HP TouchSmart 300 PC. States boundaries and drainage patterns were digitized in GIS environment from NigeriaSat-1 imagery. In addition, suitable sites for aqua-silviculture were equally digitized and the resulted maps were exported to ArcGIS version 9.3 software where the Geospatial analysis was carried out and the map of states in the study area were composed. The coordinates, that is the Eastings and Northings (UTM system) of the states were carried out in ArcGIS software. Topographic map used were on 1:50,000 scale.The result shows vast areas of Delta that are suitable for AS and great variation exist among states in terms of number and pattern of drainage channels. RS and GIS technology can be used to map areas of Delta (even the inaccessible area) that are suitable for AS thereby making it easier for the stake holders within and outside the region to practice AS.
