Upland farming systems in Lucban, Quezon [Philippines] and its ecological implications in the conservation and management of Mt. Banahaw de Lucban watershed
1993
Navasero, C.S.
The study shows that upland farmers are cultivating in Site 3. There are three farming systems identified in this site namely: vegetable-based farming system, vegetable + passion fruit-based and vegetable + coconut-based farming systems. Vegetable-based however, is the most dominant. Regression analysis revealed an inverse relationship with the farmers' number of years within the reservation and vegetable-based farming system. Vegetable + coconut-based on the other hand, is positively related to three factors namely: size of landholding, number of parcels owned and number of years within the reservation. Vegetable + passion fruit-based, however is influenced both by income and current agricultural practices prevailing in the community. Vegetable farming is the primary source of income of upland farmers. Correlation analysis shows that income is significantly correlated to the size of landholding. Farmers do not have problem on where to sell, their problem lies on the middlemen's control on prices. Soil chemical analysis revealed that Site 1 has the highest values of % OM, total N, total K and pH. On the other hand, Site 2, being the deposition area, has the highest available P. Among the three study sites, Site 3 is considered the most degraded as it show the highest erosion of 440 MT/ha. This can be attributed to low vegetable cover and destructive farm practices
