ABSTRACTS
In the Developing World, suitable land remaining for cultivation is becoming increasingly limited as unplanned landuse is shrinking the available fertile, but fragile wetlands at an alarming rate. Interestingly, most of the growing food demand originates from these regions. The spatial pattern of Fadama areas in Ile-Ife was analyzed with a view to identifying and mapping the wetland areas used for cultivation; understanding the spatial pattern of Fadama cropping; modelling areas that are favourable for Fadama farming; and examining the economic importance and constraints of Fadama to farmers. Data collection was conducted through questionnaire administration to farmers and recording of wetlands co-ordinates using a GARMIN III GPS device. Using Chi Square (X2) and Analysis of Variance (ANOVA), a number of hypotheses were tested including significance of relationship between types of crop cultivated and monthly income from the farm; farmersÂ’ perception of Fadama farming; and major constraints encountered on the farm. Standard spatial operations were carried out using ITCÂ’s ILWIS 3.2 and ArcView 3.2 GIS Software. The result reveal the pattern of Fadama cropping as mainly small-scale, self-managed level with only few farms classified as near medium-scale. The major constraints encountered by farmers are insufficient land for farming, as well as pests and diseases. Recommendations are made to ensure optimal utilization of wetlands for improved and sustainable agricultural development.
