Abstract

Fuzzy logic and Geographical Information System (GIS) based techniques were used for land suitability evaluation and production of land suitability maps for oil palm cultivation in Ife Central Local Government Area of Osun State, Southwestern Nigeria. Land and climatic characteristics data were obtained from a previous soil fertility evaluation of Ife Central Local Government Area. Ten land and climatic characteristics fitted to membership functions were used in computing land suitability index for each point observation based on the Sematic Import (SI) model. Average membership value for cation exchange capacity (CEC) is the lowest (0.216), whereas that of pH is the highest (0.809). Computed land suitability index for oil palm in the study area ranged from 0.32 to 0.52 with a mean of 0.44. CEC, annual rainfall and months of dry season with mean membership functions of 0.21, 0.22 and 0.24 respectively are the major constraints to oil palm cultivation. Land suitability map was produced using G.I.S based techniques. The use of fuzzy logic has proved valuable for identifying major constraints to oil palm cultivation. The production of suitability maps through the use of GIS techniques will further enhance decision making and strategies in overcoming these constraints.
