Abstract

Planting green fertilizer during fallow periods improves the supply of ecosystem services (ES) like soil quality, habitats and weed control. Nevertheless, farmers in Taiwan do not implement fallow practices and plant green fertilizer commonly. This is due to the current subsidy (46000 NT$ per ha) to manage fallowing of being too low. In this paper, the objective of government agriculture policy or farmer’s objective is defined as maximization of farm productivity, approximated to the value of social welfare and agricultural ecosystem services as well. Farms, which do not follow proper fallowing practices, often have poorly maintained fallow land or leave land abandoned. This results in negative environmental consequences such as cutworm infestations in abandoned land, which can affect crops in adjacent farmlands. The objectives of this study are to: 1) determine proper the fallowing subsidy based on payment for ecosystem services (PES) to entice more farmers to participate in fallowing; and 2) simulate the benefit of planting green manure in fallow land to the supply of agricultural ecosystem services, represented by the rate of farmer participation in fallow land practices and essential variables that affect soil fertility change. The approach involves a series of interviews and a developed empirical model.
