We modeled climate change impact on production of cereals in Russia. Similar to many countries of Eastern Europe, the area of intensive grain production in Russia is located in a zone with limited summer precipitation affected by frequent droughts. If climate change indeed results in higher temperatures and smaller amount of summer precipitation, as commonly predicted for this region by GCMs, the increasing frequency of droughts will negatively impact agricultural production. Even though there are many adaptation strategies that can decrease the likelihood of adverse effects on food security, the imposed political constraints can significantly reduce the agriculture adaptive capacities.  We used a modified GAEZ model and four GCM simulations to analyze the effectiveness of several common adaptation strategies. Four scenarios of market regulations (Free Market, Fortress World, Developed Socialism, and Big Commune), similar to those that were in place during different periods of the 20^th century, were used to regulate adaptation strategies. We demonstrated that adaptation effectiveness is highly limited by market regulations, and that the currently utilized “Fortress World” scenario has the lowest adaptation capacity. We also showed that under the imposed constraints the historically effective planned adaptation measures help little in future climate conditions.
