| Abstract Soil nutrient loss due to soil erosion and removal in harvest with traditional farming methods where farmers do not use any fertilisers threatens the sustainability of vegetable productions in the Philippine uplands. Consequently, poor farmers are losing incomes due to declining yields. The situation is reaching crisis point. A bio-economic analysis is used in this research to investigate the economic returns in terms of gross and net annual income over time for upland farmers from adopting alternative soil management options. Cost benefit analysis is used to compare the net returns to farmers from potential management options. A bio-physical model, SCUAF, is used to simulate the long-run tomato yields and associated soil erosion, over a... |
