A GIS-Based Multi-Criteria Approach Forsiting Large Scale Mechanised Agriculture in South East Nigeria
Résumé
Sitting and management of mechanized agriculture is necessary for the conservation and protection of natural treasures. Proper location of mechanized agriculture will help to improve the economic life of local villagers and enhance food security in the country. The unavailability of data on suitable sites for mechanized agriculture in South East Nigeria has hindered progress in implementing of large-scale mechanized agriculture, hence the need for this study. This study is aimed at the application of site suitability analysis in locating potential sites for large mechanized agriculture in South East Nigeria using geospatial technology, with a view to determining the most suitable locations for large scale mechanized Agriculture. The objectives are to establish the criteria and factors for modelling and locating Large Scale Mechanized Agriculture in the study area; classify the criteria and factors according to their rank of suitability for locating Large Scale Mechanized Agriculture in the study area; apply analytical hierarchy process on classified criteria and factors to determine suitable site for Large Scale Mechanized Agriculture within the study area; and to produce a suitable index map showing areas suitable for Large Scale Mechanized Agriculture. The methodology involved acquisition of Sentinel-2 image, geology, soil, water source and road network data, image pre-processing of the Sentinel-2 image to correct radiometric and geometric errors, image classification, SRTM processing, criteria extraction, reclassification and standardization, pairwise comparison and weighted linear combination. The results revealed that in Abia State the potential sites covered a total area of 67759.35 hectares, while Anambra State had a total area of 47656.10 hectares, Ebonyi State had a total area of 32451.69 hectares, Enugu State had a total area of 179589.65 and Imo State had a total area of 54409.75 hectares. The study successfully applied site suitability analysis in locating potential sites for large scale mechanized agriculture using geospatial technology. The analytical hierarchy process approach is therefore recommended for use in large scale mechanized agriculture location planning and decision making in South-eastern Nigeria and other regions as well.
