| Abstract | This thesis work presents the results of the study conducted at Metro Cebu, Cebu Philippines for a holistic approach of looking at the factors that affect the complex agricultural system where a computer PC ARC-INFO software was employed in the spatial analysis of physical parameters at the macro level. A socio-economic data, farm management and cropping patterns were gathered from a sample municipality to provide baseline information for a comprehensive crop management plan at the micro-level with the aim to increase or sustain farm productivity and increase farmer's income. At the macro-level, physical parameters encompassing rainfall, temperature, slope, land cover/vegetation, soil type(texture), pH, organic matter, phosphorous, potassium and erosion potential were considered in the spatial analysis of data wherein a linear combination method for land suitability analysis was employed. Unequal weights of importance were assigned to the different parameters considered such that the derived land suitability for corn, ginger, cutflowers, fruit trees, rootcrops, leguminous crops, solanaceous crops and cucurbits(squash family) was deduced as a weighted sum of several factors. The erosion potential map was derived also by linear combination model where slope, land cover/vegetation and soil type were treated equally based on local conditions. The derived land suitability were based from FAO(l976) international framework where Sl is highly suitable, S2 is moderately suitable, S3 is marginally suitable and S4 is not suitable. At the micro-level, rapid rural appraisal (RRA) methodology was employed to gather socio-economic data, farming practices, and cropping patterns as baseline data for a comprehensive crop management plan which is location-specific, low-cost and sustaining for both the lowland and upland development zones of Compostela,Cebu, the site of the micro-analysis. Based on the results of the spatial analysis and the socio-economic study, a comprehensive plan was formulated that will hopefully increase farmers' productivity and income. |
