Adaption To Climate Change Through Fallow Rotation In The U.S. Pacific Northwest

In this paper, we study the use of wheat land fallow production systems as a climate change adaptation strategy. Using data from the U.S. Census of Agriculture, we find that fallow is an important adaption strategy for wheat farms in the U.S. Pacific Northwest region. In particular, we find that a warmer and wetter climate increases the share of fallow in total cropland and thus reduces cropland in production. Our simulations project that, on average by 2050, the share of fallow (1.5 million acres in 2012) in the U.S. Pacific Northwest region will increase by 1.3% (0.12 million acres) under a medium climate change scenario and by 1.8% (0.16 million acres) under a high climate change scenario.
