The demand of energy and food production will grow as rapid population increase. However, although it is closely related to food habitat change, water resource, and bioenergy boom, a comprehensive understanding integrated with food, water and bioenergy has been rarely documented. Our aim in this study is to investigate the effect of agricultural land and bioenergy potential in global scale using water resources model H08. We use five future food consumption scenarios, which are composed of 10 food categories. Two different land-cover types, abandoned land and fallow land, are defined as potential area for cultivation of food-producing and biofuel-producing crop. The estimated global bio-energy potential is 57-200 [EJ]. It is highly related to increased land demand for large-scale food production based on the scenarios. In particular, the cereals consumption for fodder production is significantly changed on the basis of the land-use scenario. It implies that future energy and food security will critically depend on livestock food consumption.
