Research Description

It is important to clarify the impact of climate change on crop productivity, and that is very important issue from the viewpoint of decision-making. However, crop yield model that can be predicted in a wide region and stably has not realized because of
1) difference of cultivatation technology and terrain environment,
2) Difficulty of taking into account the cultivation technology factors such as diffeerences in breed,
3) Non-linear characteristics of the crop growth and complextiy of the ecosystem,
4) Uncertainties between crop growh and physical and chamical soil properties.

Based on above evaluation, I am developing the global and regional crop model that is used as input data (soil, water, climate, crop characteristics, and field management). Also, daily crop evapotranspiration, biomass and yield can be obtained as daily output value. The yield prediction technique is the important tool for that can be incorporated as a possible use decision support system on the farmers judgement. In the study, I begin the development of a new stable crop yield prediction model through the integration of observation data and crop yield model. In addition, I have a study on the impacts of climate change on crop productivity.

About TUAT's tenure-track program

I think for the start-up funds is sufficiently secured, that to build progresses smoothly the research environment. To take the tenure position, I think there is room for some improvement.

Future aspirations

Because I'm given the research environment, I amd conducting research steadily.At the same time, we believe that to develop further and joint research with researchers and companies in other fields, and if possible even more dramatically. I think while maintaning a balance of research and eduction, and want to make a laboratory lively.
