Professor Avril Horne – Dr Andrew John | Re-evaluating How We Assess and Manage Rivers in Response to Climate Change
Understanding and successfully managing river flows is vital for sustaining human communities, the river environment, and its ecosystems. However, the methods currently used to assess river flow needs are limited in the face of increasing pressures from an uncertain and changing climate. Academics at the University of Melbourne are rethinking the approach to these assessments. This includes work by Professor Avril Horne, Dr Andrew John and their collaborators to present a more integrated and holistic method, which provides much-needed room for learning over time, and to understand the vulnerability, robustness, and adaptability of river flow regimes.
The COVID-19 pandemic forced many universities to deliver their courses online, exposing the limitations of remote learning strategies. Dr Barrett Caldwell and his team at Purdue University devised a new approach that could help to improve online courses in different engineering subjects. The approach builds on his experience while teaching and developing the ‘Perspectives on Systems Engineering’ course, which is part of the curriculum for the Systems Engineering program at Purdue University.
Future food security is one of the key global challenges facing society. Climate change presents significant threats to our ability to produce staple food crops – particularly in regions already vulnerable to droughts. Dr Kahiu Ngugi and his research team from the University of Nairobi and other institutions in Kenya investigated numerous varieties of sorghum – one of the world’s most important cereal crops. Their aim was to find new genes that would allow the crop to withstand both drought and a common parasitic weed.
Dr Carlos Rodriguez-Franco | Dr Deborah Page-Dumroese – Healing Abandoned Mine Ecosystems with Biochar
The Gold Rush of the 1800s is inextricably tied to USA history. Mining towns popped up wherever precious metals could be extracted, with many of these towns and mines now lying abandoned as ghostly reminders of the old wild west. Abandoned mine land poses a threat to environmental and human health, and methods to rehabilitate this land has gathered much interest over the past few years. Dr Carlos Rodriguez-Franco and Dr Deborah Page-Dumroese from the US Department of Agriculture have been evaluating the use of biochar as a sustainable method to remediate abandoned mine lands.
