| A mathematical programming model is developed and associated to a spatial pattern index (Ripley L function) to analyse the optimal reserve design and implementation for the Little Bustard conservation in Plaine de Niort. The model structure corresponds to three spatial levels, fields, farm and landscape. Simple in terms of area representation, it is detailed in terms of farm behaviour and spatially explicit. The model is applied in a normative and in a positive way. The major findings of the normative approach relate to the trade-offs between the reserve pattern and its cost. It was found that the environmentally optimal reserve, which is randomly dispersed across the zone, is the most costly one. Within the positive approach, it is illustrated that the... |

| The European Union has launched an ambitious policy aiming at increasing the use of biofuels in land transport “with a view to contributing to objectives such as meeting climate change commitments, environmentally friendly security of supply and promoting renewable energy sources”. Another motivation, at least for some member states, is that the development of biofuels is expected to provide larger outlets for domestic farm products and new employment opportunities in rural areas and make future adjustments of the Common agricultural policy easier. The EU policy of support to energy crops, tax exemption for biofuels and mandatory incorporation targets in some member states, has resulted in a significant increase in the demand and supply of biofuels. The... |

| The paper provides background information regarding the EU policy on biofuels. The purpose is to assess whether this policy may lead to an increased use of European agricultural products to provide energy, or whether it is more likely that the EU will shift towards imports of biofuels. The paper first describes the EU support policy for energy crops, i.e. tax exemption for biofuels and mandatory incorporation taxes in some member states, the impact on demand and supply of biofuels. It then focuses on the prospects for the production and utilization of biofuels in the EU. The paper addresses the three related issues of energy efficiency, environmental benefits and cost competitiveness of EU biofuels and presents simulations regarding the competition between... |
