In this engaging discussion, science reporter Dan Charles sheds light on why some experts argue for letting abandoned land reclaim its natural state. Ecologist Gergana Daskalova shares her personal journey back to her deserted Bulgarian village, exploring how urban migration impacts rural communities. They debate the balance between stewardship and allowing nature to flourish on its own. Listeners discover the complexities of biodiversity in these changing environments and the innovative strategies for managing abandoned land as agriculture shifts.
Gergana Daskalova's return to her childhood Bulgarian village highlights the personal narratives entwined with the phenomenon of land abandonment.
The podcast explores the debate on whether to allow abandoned lands to recover naturally or maintain human involvement for biodiversity.

The Legacy of Abandoned Farmland
Many forests in the eastern United States are remnants of previously productive farmland that has since been abandoned. This phenomenon, often referred to as ecological succession, describes how ecosystems can regenerate after human activity ceases. Settlers cleared vast areas for farming, but as agricultural viability diminished, these lands reverted to forest. The discussion highlights that similar abandonment is occurring globally, particularly in regions like Eastern Europe and South Asia, raising important ecological questions about the nature of these returning landscapes.
Local Voices and Personal Connections
The personal narrative of Gergana Daskalova illustrates the intimate connection between land abandonment and individual stories. Having spent her childhood in a small Bulgarian village, she witnessed firsthand the migration of people to cities, resulting in numerous abandoned houses and fields. Her relationship with this land deepens her research into the ecological implications of abandonment, as she seeks to uncover what happens to ecosystems when human stewardship is removed. Gergana's experiences underscore the broader shifts in rural communities struggling with depopulation and declining farming practices.
Biodiversity and Human Influence
The impact of land abandonment on biodiversity presents a complex debate between restoration and maintenance. Some studies indicate that without human intervention, areas may suffer from reduced biodiversity due to invasive species and loss of cultivated plants, while others advocate for allowing nature to thrive unimpeded. The challenge lies in assessing whether abandoned lands can return to a natural state beneficial for diverse species or if human-managed landscapes provide a richer ecological habitat. Ecologists continue to explore these questions, seeking insights from various global contexts to inform future conservation strategies.
Ecologist Gergana Daskalova moved back to the small Bulgarian town of her childhood. It's a place many people have abandoned — and that's the very reason she returned. At the same time as land is being cleared around the world to make room for agriculture, elsewhere farmland is being abandoned for nature to reclaim. But what happens when people let the land return to nature? This episode, science reporter Dan Charles explains why abandoned land has conservationists and researchers asking: If we love nature, do we tend it or set it free?
