renewable energy subsidies, culture (such as acceptance to new technologies and new energy sources) and alternatives to biomass.There are extensive debates on the impacts of biomass production on food production/markets (e.g.Wang et al. [7]). The food production or markets is determined by the supply and demand of food. Any factors which influence the supply-demand relation of food will impact food production or markets. For example, the increase in food yield due to new technology will provide more food and therefore may result in low market price of food. If the massive utilization of biomass imposes a significant impact on the supplydemand
relation of food, then food production or markets will be influenced. Conversely, if the supply-demand relationship is not affected, then food production or markets will remain stable. For
example, even though the increased demand for biomass may cause farmers to convert more land for biomass, the production or markets of food will be not impacted if the supply and demand of
food remains stable.
