How Can We Promote Sustainable Regional Development and Biodiversity Conservation in Regions with Demographic Decline? The Case of UNESCO Biosphere Reserve Elbe River Landscape Brandenburg, Germany
2022
Erik Aschenbrand
This paper analyzes the relationship between out-migration from rural areas, sustainable regional development and the conservation of biodiversity. Urbanization is a key challenge for sustainable development. Will the move to cities reduce land use pressures on rural areas, and thus provide opportunities for biodiversity conservation? This paper reviews the literature on the relationship between rural out-migration and biodiversity. Generalizing statements or even predictions are rarely possible, as regional contexts differ greatly and a multitude of factors are at work. It is apparent, however, that traditional land use practices, in particular, are in decline as a result of out-migration. In some cases, this can lead to intensification, in others to abandonment, while some studies do not show any link at all. The paper then considers the case study of a peripheral biosphere reserve in Germany that is characterized by strong out-migration. Here, the urbanization tendency is evident on a smaller scale; the regional urban center consolidates, and the small communities face great challenges. At the same time, new innovative actors are emerging. It is essential for new and established actors to collaborate and jointly develop new narratives for “shrinking” regions.
