报告摘要：Motivated by the fresh produce industry, this paper studies the decisions faced by a farmer growing a single crop: land cultivation, fertilizer application, and crop harvesting. We develop a two-stage stochastic program capturing uncertainties in both yield and harvesting labor cost as well as the effect of fertilizer on the total yield. We characterize the farmer’s optimal decisions as well as the impact of these two uncertainties on the farmer’s optimal decisions and profitability. Based on models calibrated to data: 1) we find that there is a significant value using our integrated optimization model over commonly used heuristics in practice; 2) we quantify how the uncertainties in the farm yield and harvesting labor cost affect two sustainable measures---the yield gap (i.e., the gap between the theoretical maximum yield and the actual yield) and food losses (i.e., unharvested crops). Our findings not only aid farmers in making farm planning decisions but also provide some insights into how policymakers could tackle the food security challenges by encouraging farmers to close the yield gap and reduce food waste.
