| In the context of ever-increasing petroleum prices combined with concerns about climate change, timing of adoption and rate of diffusion of land-based fuels and backstop technologies for transportation use are examined in this paper. A global model of land allocation joined with a Hotelling model has been developed. Using this framework, effects of climate and energy policies on world agricultural and energy markets have been explored. Further, their regional impacts are also analyzed. Whereas mandatory blending bio-fuels have substantial effects on world food prices and do not succeed in curbing down carbon emissions fluxes, carbon targets are expected to speed up date of adoption of backstop technologies. Then, sensitivity scenarios with regards to... |

| In order to assess the future world food demand/supply balance for the next century, in relation to the land uses, we develop a model in which the society has to supply two types of food demand, namely, processed crop products and meat and dairy products. From the supply side, the society can resort to different classes of land. Each class of land can be allocated wholly or partially either to crop cultivation or to pasture or last to be lain fallow. Primary crop production can be transformed either into processed crop products to satisfy final needs, or into intermediate livestock products used as inputs within the intensive industrial farming system. The livestock products can also be obtained from the extensive grazing system. The increase in world... |
