| We present here preliminary results of an integrated modelling approach combining a crop model (STICS) and an economic model (AROPAj) of European agricultural supply. This modelling framework is designed to perform quantitative analysis, regarding climate change impacts on agriculture and more generally the interactions between soils, land use, agriculture and climate integrating physical and economical elements (data, process, models). It explicitly integrates an agricultural diversity dimension with regards to economic set of choices and soil climate spatial variability. First results are given in term of quantitative analysis combining optimal land allocation (economic optimality) and “dose-response” functions related to a large set of crops in Europe,... |

| Assessing climate change impact on agriculture is a complex task involving a wide range of economical and physical processes, leading to significant uncertainties. At European scale, climate change impacts on agricultural supply have been appraised to be of relatively less important driver by the end of century compared to other global drivers. However these diagnoses are incomplete due to a limited representation of both spatial heterogeneity in important determinants of agricultural supply (soil, management practices and producer typology) and fine scale processes such as farm scale autonomous adaptation. We propose a complementary approach based on a modeling framework including a spatially explicit representation of productivity and producer behavior... |

| This paper addresses the assessment of greenhouse gas emissions from agriculture in the European Union. We first estimate and compare net emissions from agricultural activities in twelve EU countries. These estimates are based on a set of farm-unit linear-programming models. We then use these models to derive marginal and total abatement costs associated with different levels of reduction targets (dual approach) and different values of carbon-equivalent emissions (primal approach). Finally, we explore the possibility of allowing afforestation on set-aside land. This paper highlights the discrepancies between countries regarding abatement costs and their sensitiveness to the accounting for carbon sequestration. |

| In this paper, we analyze the simultaneous regulation of several goods produced on agricultural land such as environmental amenities and crops. This analysis is conducted using a general two goods model where all agricultural land is used for production. The regulation authority can regulate these goods either through set aside requirements or production quotas. The paper focuses on information asymmetry about some farm performance index creating adverse selection. When public funds are non costly we show that the net social welfare induced by the two types of contracts are equal. In general we also show that if the goal of the regulation is to decrease the production of the quota good it is better to use the quota contract. On contrary if the... |
