Socio-economic analysis of soil conservation practices on upland production system in Cebu [Philippines]
1989
Silva, N.L.
The conservation practices considered in the analysis were crop diversification, stone terracing and napier grass contouring. The demographic variables characterizing the conservation adoptors and non-adoptors and which were found to have significant differences in the means were age, household size, years in farming, and years of residence. The average net profit earned by the farmers in corn production was P2,986.61 per hectare. It was observed that almost all farmers used their entire corn production for home consumption. Hence, the farms may be considered subsistence farms. Results of the production function analysis revealed that the significant variables affecting corn output were labor and farm slope. The coefficient of labor was positive, indicating that for every percent increase in labor, output increases by half percent. On the other hand, the output elasticity of land slope was -0.182 and the marginal loss of corn production due to erosion in the farm was computed at 2.43 kg. Conservation farming was found acceptable to the farmers of Jampang as indicated by the high percentage (95%) of adoptors. Among the practices, stone terracing was found to be a more effective means of conservation than napier grass contouring in terms of the ability to reduce erosion and increase corn output. The effect of crop diversification, on the other hand, should be evaluated not only in terms of corn output but also of the whole farm enterprise itself.
