Abstract
A model to find a balance of human impacts and the global environmelt from the view point of food and energy is discussed. This model consists of satellite data and Edmonds & Reilly (E-R) model. The farmer combined with weather data and soil maps (ex. ISRIC data) can monitor the suitable place for cultivation and plantation and estimate the amount of CO2 fixation. And the latter can estimate the CO2 discharge. From the model proposed in this stud, ywe can find the CO2 discharge when the population becomes the limit by E-R model, and can find the place for cultivation and plantation simultaneously
