Shinichiro Fujimori, Associate Professor of the Graduate School of Engineering, Kyoto University, collaborated with the National Institute for Environmental Studies and the Institute for International Applied Systems to investigate the impact of climate change and greenhouse gas emission reduction measures by 2050 on agriculture. Greenhouse gas reduction measures have been found to increase the risk of starvation.The research group says that various policy options should be taken for food security.
According to Kyoto University, the research group used multiple global agricultural economic models to assess the impact of climate change and greenhouse gas reduction measures on food security by 2050.As a result, it was found that if measures are taken according to economic rationality, the impact of greenhouse gas reduction measures is greater than the change in crop yield due to climate change.
Taxes on methane and nitrous oxide emitted from the agricultural sector will partially cover the costs of greenhouse gas reduction measures, resulting in higher food prices, lower per capita food consumption and increased hunger risk. Means that is born.
Based on the results of this study, the research group considers not only the economic rationality of greenhouse gas reduction measures, but also low-income people facing hunger risk, regional characteristics, etc., and changes the carbon tax rate depending on the sector, direct emissions. It recommends the adoption of various policy options, such as regulating carbon tax revenues and allocating carbon tax revenues to food security measures.
