text: In response to production changes, the price of each commodity changes under both scenarios. At the global 
  level, the market price for maize would increase by 0.7% and 3.4% under 1.5 °C scenario and 2.0 °C scenario, 
  respectively, which would vary quite largely among different countries and regions under both climate change 
  scenarios (Fig. 7). Particularly, the market price would increase by around 22% and 27% in Iran under 2.0 °C 
  scenario and 1.5 °C scenario, respectively. Iran is also the region where the highest yield reduction is observed 
  due to climate change. Market prices for maize in India, Mexico, Russia, South Africa and the Rest of Africa 
  would decrease significantly under both scenarios, as their yields improve due to climate effects. Along with the 
  domestic production, the climate change will also induce changes in international trade of maize, resulting in 
  changing levels of self-sufficiency ratios (SSR) for each country/region. By SSR, we mean the ratio of domestically 
  produced commodity, to the sum of net imports and domestic production. In our scenario analysis, generally, 
  the countries that face positive effects on yields and/or are relatively less dependent on imports, are positively 
  (less negatively) affected by climate change. For example, maize SSR for Ukraine, India, Russia and Mexico would 
  improve under both scenarios (Fig. 8). Whereas the self-sufficiency ratios of maize for Southeast Asia, Bangladesh 
  and Iran will worsen under both scenarios. China’s SSR for maize stays almost similar to the level as the baseline.
