This analysis quantifies changesin global agricultural markets for maize, rice, soybeans, and wheat due to yield changes triggered by climate change. The scenarios include four representative concentration pathways (RCP), five global climate models, three shared socioeconomic pathways (SSPs) capturing differences in population levels and economic growth, and enhanced COurn:x-wiley:01695150:media:agec12660:agec12660-math-0001-fertilization. Yield projections incorporate the influence of SSPs on nitrogen application and agricultural technology. Depending on the SSP and comparing the RCP8.5 ensemble yields (with COurn:x-wiley:01695150:media:agec12660:agec12660-math-0002-fertilization) to a no climate change scenario in 2050, price increases for maize (61.3%–80.9%), soybeans (36.7%–51.7%), and wheat (5.4%–11.1%) are observed. Large wheat producers in temperate regions expand wheat production under climate change. Rice benefits from COurn:x-wiley:01695150:media:agec12660:agec12660-math-0003 fertilization resulting in a relatively uniform price decrease across scenarios of 19.5%–19.9%. Cropland expansion between 2015 and 2050 is lowest for the high economic growth scenario. Depending on the crop and region, there are significant reductions in production especially for maize. Absolute changes in trade patterns are most pronounced for wheat and least for rice. Using trade as a means to dampen the negative welfare effects of climate change will be important and so is economic growth.

China is a major importer of agricultural products and we examine retaliatory tariffs imposed by China on U.S. pork, soybeans, corn, and wheat. We use an agricultural trade model to determine the impacts on agricultural commodity markets and combine our results with an input‐output model to measure economic effects in the United States...

The increase in the demand for biofuels as a result of biofuel-friendly policies and market forces has led to higher crop prices.

The production cost of biofuels is a major determinant of their potential contribution as alternative sources of energy. This chapter provides a review of the literature on production costs of first and second generation biofuels, including a breakdown of their main components. In the process we highlight some of the resasons behind the widely divergent cost estimates that have been published.
