Abstract The agricultural landscape of Mediterranean islands has transformed radically over the last 60 years. The results differ, due to the interplay of macro, national, and local factors for each setting. In this study, some of these trajectories of change are examined for the island of Lemnos in Greece, using remote sensing and oral history techniques. The first aim is to present the changes in and of the agricultural landscape of Lemnos, applying quantitative and qualitative methods, in order to capture different aspects of those changes. The second aim is to identify the socio-economic factors that underlie landscape changes or lack of, using local knowledge and perception of the landscape. Land cover maps were produced by aerial photographs using additional texture features, for 1960, 1980, and 2002, through object-oriented image analysis (OBIA). Interviews and a workshop with local actors were used to validate and understand different change trajectories, and to identify the factors behind these changes. Results show that although grasslands have increased, revealing a process of extensification of agriculture in the study area, change has affected a small proportion of the landscape. This process is backed by information revealed through qualitative methods, as migration of labor power in the 1960s and mechanization of the agricultural sector in the late 1970s and early 1980s have been the main factors of the transformation of the agricultural sector in Lemnos, resulting in bigger mixed crop-livestock farms and the abandonment of marginal areas. The results of these processes are discussed in the context of agricultural change in the Mediterranean.

Lemnos 农业景观的地图变化

摘要 在过去的 60 年里，地中海岛屿的农业景观发生了根本性的变化。由于每个环境的宏观、国家和地方因素的相互作用，结果各不相同。在这项研究中，使用遥感和口述历史技术检查了希腊莱姆诺斯岛的一些变化轨迹。第一个目的是展示 Lemnos 农业景观的变化，应用定量和定性方法，以捕捉这些变化的不同方面。第二个目标是利用当地对景观的知识和感知，确定导致景观变化或缺乏的社会经济因素。土地覆盖图是通过使用附加纹理特征的航拍照片制作的，用于 1960、1980 和 2002，通过面向对象的图像分析（OBIA）。与当地参与者的访谈和研讨会被用来验证和理解不同的变化轨迹，并确定这些变化背后的因素。结果表明，虽然草地增加，揭示了研究区农业扩张的过程，但变化影响了一小部分景观。这一过程得到了通过定性方法揭示的信息的支持，因为 1960 年代的劳动力迁移和 1970 年代末和 1980 年代初的农业部门机械化是莱姆诺斯农业部门转型的主要因素，导致更大的农牧混合农场和废弃边缘地区。
