Preface - Migration and the Environment: Some Reflections on Current Legal Issues and Possible Ways Forward

The link between migration and the environment is not new, environmental conditions have always influenced human mobility. However, the nature, the dynamics and the scale of environment related migration have dramatically changed in recent years, and the complex nexus between migration and the environment has drawn increasing attention in the contemporary international context. This relationship is not easy to outline for several reasons, including the range of environmental phe- nomena that may cause migration flows (natural disaster as well as gradual process of environmental deterioration), the difficulty of isolating environmental factors from other political, social and eco- nomic drivers of migration, the complexity of differentiating between forced and voluntary migra- tions in cases of environment-induced flows. In addition, from a different perspective, migratory flows may contribute to environmental degradation in the areas of destination and transit, giving rise to phenomena such as unmanaged urbanization or temporary camps or shelter that produce further pressure on the environment. The complexity of the link between migration and the environment challenges the current legal par- adigm in which migration is largely framed and calls into question the adequacy of the existing pro- tection frameworks. In several international fora, it is increasingly recognized that there are certain groups of people who move for environmental reasons and are in need of assistance and who currently fall outside of the scope of international protection. The goal of the volume on Migration and the Environment: Some Reflections on Current Legal Issues and Possible Ways Forward is to discuss the extent to which people whose movements are induced by environmental factors are protected under the existing international legal framework, to investigate the main legal issues and the normative gaps and to analyze the solutions being discussed in the international arena.
