ABSTRACT This themed section is aimed at presenting different contributes on climatic-environmental migration. With this paper we set out to provide an introduction of the subject: this includes a general review of relevant publications and a brief analysis of global scenarios. The second part of the paper gives a general interpretation of the issue, using a historical-social procedural method, of the global ecology of migrations. The ecological approach is based on the need to integrate the geographical and the historical aspects of the subject, and to consider both local and global dimensions. The authors examine the subject of climatic-environmental migration up to the present day, demonstrating the complex relations between environmental and geopolitical issues as determiners of migratorial phenomena. An analysis of the relations between climatic-environmental migration and urban dynamics draws the reader’s attention to certain problematic areas and potential vicious circles, most notably the problem of urban gigantism, especially in river delta areas, in African and Asiatic cities. We conclude with an introduction of the five papers of the theme section. One is on the effects of environmental change on migration in the future, and possible policy responses and the other one is on environmental racism and migrations.

迈向全球移民生态学：气候环境移民简介

摘要 本主题部分旨在展示对气候-环境迁移的不同贡献。在本文中，我们着手介绍该主题：包括对相关出版物的一般审查和对全球情景的简要分析。本文的第二部分使用历史-社会程序方法对全球移民生态学问题进行了一般性解释。生态方法是基于需要整合主题的地理和历史方面，并考虑本地和全球层面。作者研究了时至今日的气候-环境移民主题，展示了环境和地缘政治问题之间的复杂关系，作为移民现象的决定因素。对气候环境迁移与城市动态之间关系的分析将读者的注意力吸引到某些有问题的领域和潜在的恶性循环上，尤其是城市巨人化问题，尤其是在河流三角洲地区、非洲和亚洲城市。最后介绍主题部分的五篇论文。一个是关于环境变化对未来移民的影响，以及可能的政策反应，另一个是关于环境种族主义和移民。
