ABSTRACT

The relationship between land values, climate and landscape diversity is investigated for a region of the Mediterranean where climate impacts are expected to be particularly severe. The Ricardian approach is applied, and spatial correlation and endogenous selection of farm type are accounted for. The analysis is at the farm level, and it is completely geocoded. It is found that farmland value is affected by both climate and landscape agrobiodiversity, and that their impacts differ across models. However, landscape agrobiodiversity is extremely significant, and it greatly contributes to sustaining the mean level of land value. The results show that spatial correlation and the endogenous nature of adaptation substantially affect impacts assessment and suggest that spatial dependence and adaptation should not be overlooked in Ricardian models.

摘要

对地中海地区的土地价值，气候和景观多样性之间的关系进行了调查，预计该地区的气候影响将特别严重。应用Ricardian方法，并考虑了空间相关性和农场类型的内生选择。该分析是在服务器场一级的，并且已完全进行地理编码。发现农田价值受气候和景观农业生物多样性的影响，并且其影响因模型而异。但是，景观农业生物多样性极为重要，它极大地有助于维持平均土地价值。结果表明，空间相关性和适应性的内生性实质上影响了影响评估，并表明在Ricardian模型中不应该忽视空间依赖性和适应性。
