About this episode
Invasive plants can permanently alter ecosystems to promote conditions that support their own persistence. For example, certain invasive grasses can make areas prone to more frequent and larger wildfires, which negatively impact native species but favour fire-resistant invaders. This self-perpetuating process, termed a grass-fire cycle, can be impossible to reverse. Dr Jeanne Chambers of the United States Department of Agriculture’s Rocky Mountain Research Station and her colleagues – Matt Brooks, Matt Germino, Jeremy Maestas, David Board, Matt Jones, and Brady Allred – recently examined how an ecosystem’s resilience to fire and resistance to invasive grasses influence whether a grass-fire cycle will establish. In their paper, the scientists introduced a geospatial tool and decision matrix that incorporate measures of ecological resilience and resistance to invasive grasses for designing management strategies to combat grass-fire cycles.

Professor Mark Jarzombek | A House Deconstructed: Uncovering the Hidden History of the Modern House
The full extent of the labour and resources which go into creating a modern house is hidden deeply within the buildings we call home. Professor Mark Jarzombek of MIT and Professor Vikramaditya Prakash of the University of Washington are co-founders of the Office of Uncertainty Research, a research collaboration that is dedicated to rethinking architecture in a modern context. Through their research, Jarzombek and Prakash investigate these hidden stories by exploring the history of a recently built modern house in Seattle. Their findings reveal that the presumed transparency of modern architecture conceals deep ethical and environmental challenges, inspiring a call for a critical reassessment of how our current construction practices should be understood and approached.
Julius Reiff | Soil, Seeds, and Sustainability: The Power of Permaculture during Environmental Breakdown
Pressing environmental challenges, such as soil degradation, biodiversity loss, and climate change, can negatively affect agriculture, while also being driven by common agricultural practices. To tackle this predicament and ensure food security while promoting environmental sustainability, innovative agricultural practices are essential. Permaculture, a holistic approach to farming that mimics the stability and resilience of natural ecosystems, offers a promising solution. A recent study conducted by Julius Reiff of the Institute for Environmental Science, RPTU University of Kaiserslautern-Landau, Germany, and colleagues, provides compelling evidence of the benefits of permaculture in enhancing carbon stocks, improving soil quality, and boosting biodiversity.
Dr Alan Cottey | How we can Improve our Science Communication to Create Climate Crisis Action
We are facing a climate crisis that threatens our entire world and life as we know it. Despite this, scientists have found it difficult to engage people on the issue and inspire effective action. Dr Alan Cottey at the University of East Anglia explores the history of scientists’ climate warnings and suggests a four-register model of communication that he believes has the potential to reach people with varying degrees of scientific literacy and different lifestyles.
Dr Piergiorgio Gentile | Utilising Cocoa Pod Waste to Improve the Sustainability of Chocolate
With a history as rich as its flavour, chocolate in its various forms has been loved by people for over 5000 years. Currently, however, chocolate is facing a serious threat. The improper disposal of cocoa waste products is spreading devastating diseases through cocoa crops across the world. To address this serious problem, Dr Piergiorgio Gentile from Newcastle University and Dr Joel Girón-Hernández from Northumbria University with their collaborators have been exploring new uses for cocoa waste products, to increase sustainability and prevent the spread of crop diseases.
