[U10-03] Agricultural impact assessment and adaptation research in Japan using climate change scenarios at multiple scales

★Invited Papers

Keywords:Climate adaptation, Agricultural production, Regional climate projection scenarios

Climate change is already affecting agricultural production, and their impacts will become more significant if stringent mitigation measures are not implemented. Such impacts have occurred through various mechanisms, from the field scale to the continental and global scales. Therefore, highly accurate information on climate change projections is needed to assess the impact of climate change on agriculture at various spatio-temporal scales and to develop locally appropriate adaptation measures.
Our research strategy in NIAES/NARO is how crops respond to environmental changes such as increases in atmospheric CO2 concentration, global warming, and changes in precipitation, which will be utilized for projecting the impacts and assessing effective adaptation measures. The characteristics of the studies are integrating, data collections and quality control, climate change scenario development, and crop modeling and simulations are mainly carried out by ourselves. From incremental to transformative methods, agricultural adaptation strategies to climate impacts are also systematized by us.
We have developed and published a regional climate scenario with a 1km squared grid, which relies on the projections of general circulation (global climate) models. We know very little about the increase in greenhouse gas emissions and the associated climate change itself, but we have detailed knowledge on regional agro-meteorological phenomenon and its impacts. The climate modeling community, which Prof. Manabe has established and rapidly developed, and we, as climate and agriculture intermediaries and impact researchers, will work together to adapt wisely to the growing impacts of climate change.
