Terrestrial ecosystems, such as forests, grasslands, and deserts, exchange heat, water, and carbon dioxide with the atmosphere. The temporal and spatial distribution of these exchange rates is a major factor in determining the Earth’s climate.
On the other hand, climate change and human activities can drastically change the shape of terrestrial ecosystems. This makes it more likely that the global environment will further increase the rate of change. Therefore, in order to predict the future global environment, we need a tool called a terrestrial ecosystem model that can reproduce the functions of ecosystems such as photosynthesis and respiration. I am currently using this terrestrial ecosystem model to study how the activities of forests and grasslands will change in the future on a European and global scale.
