Climate Conscious Farming

Dr. Ted Yeap

Waller

   Tet H. Yeap received the B.A.Sc. degree in electrical engineering from Queen’s University, Canada, in 1982, and the M.A.Sc. and Ph.D. degrees in electrical engineering from the University of Toronto, Canada, in 1984 and 1991, respectively. He is currently a Professor of systems science with the School of Electrical Engineering and Computer Science, University of Ottawa, Ottawa, ON, Canada. He is also the Director of the Systems Science Program and the Bell Canada Advanced Research Laboratory, Ottawa.
   Thank you for the invitation. It would be my honor to share with your group the 3-year results of working on precision farming, trying to mitigate the disastrous effect of nitrous oxide from our farmland on climate warming. Our research at Area X.O. has achieved 33% savings on fertilizer usage, a 30% increase in yield, and a 90% reduction in nitrous oxide emissions with precision farming. Our work is tested on 100 acres of farmland at the corner of Woodroffe and Hunt Club.
   Agriculture plays a substantial role in greenhouse gas emissions, and finding environmentally friendly and economically viable practices is crucial for addressing climate change and ensuring the long-term sustainability of the farming industry. A modern farming practice called Enhanced Strip-till is introduced in this paper. Compared with the widespread Conventional Broadcast farming practice, the new farming practice can achieve more than a 90% reduction in nitrous oxide emissions, a 33% reduction in fertilizer use, and a 26% increase in yield. Adopting and promoting such a sustainable farming practice is essential for the agricultural sector to transition towards more environmentally friendly and economically viable models. It's a positive step forward in balancing food production with environmental conservation, aligning with the goals of sustainable agriculture and responsible resource management

What happened to Emelia Earhart?

Dr. Ian Mackay

Waller

   Many of us know of Amelia Earhart only as a flyer who disappeared sometime in the first half of the 20th century, and that her fate is a great, enduring mystery. There are also a sizable number of conspiracy theories explaining that mystery, ranging from a popular one based on the plot of the 1943 movie starring Rosalind Russell and Fred MacMurray to the usual suspects: aliens and foreigners.
   The truth is more straightforward. Today, there is an enormous weight of individual but interlocking pieces of evidence that precisely outline her fate. What is more shocking is that quite a number of influential people had strong suspicions within days of her disappearance as to where she ended up – and they were right – in plenty of time to have rescued her and saved her from a truly miserable fate. But incompetence, prejudice, lack of communication, and the hierarchical nature of command let her down. This story is a classic case of the truism “Never attribute to conspiracy what can be explained by ego, stupidity, incompetence and bad luck.”   The evidence that pointed to her location in 1937 still points there but is supplemented by a great deal of evidence discovered in 1940, plus a wealth of evidence assembled in the past 30 years. Join us for a story full of twists and turns and many surprises.
   Ian is retired from a 40-year career as a professor in the Department of Linguistics, University of Ottawa, where he taught in both official languages. Much of his research involved the acquisition of pronunciation when learning a second language at various starting ages. He also taught a graduate seminar on the origins of human language.
   For more than a decade Ian has been closely following developments in the search for answers to Amelia Earhart’s fate, While textbook writing is no tutorial for novel writing, he is attempting to write a historical novel based on the famous venture during which Earhart disappeared. While a novel demands at least some fiction, Ian’s talk on Earhart sticks to the facts as best they can be determined.
