Sam McColl

7.30 pm Tuesday, 20 May, Palmerston North Central Library, George Street, Palmerston North

Held jointly with the Geoscience Society of New Zealand

Sam McColl is a quantitative geomorphologist who applies cross-disciplinary approaches to solve problems spanning natural hazards, agriculture, engineering, and environment, with primary expertise in landslide processes and Quaternary geomorphology. He is the Engineering Geology Team Leader at GNS Science and the current President of the Geoscience Society of New Zealand.

Sam will take you on a foray through the fascinating world of landslides, from the unbelievably large landslides on Mars to common problems in your back yard. The talk will explore why New Zealand has so many landslides and why they cost more than any other natural hazard. Some thoughts will be given to the big questions in landslide science and projections for landslides in a warming world.

Isabel Castro

7.30 pm Tuesday, 15 April, Palmerston North Central Library, George Street, Palmerston North

Kiwi ancestors were the lucky ones to survive the dinosaur extinction 66 million years ago, and today they remain the closest extant branch of the dinosaurs, or, if you wish, the lowest branch of birds. Their physiology, behaviour, and genetics continue to fascinate us. Isabel Castro and her team have been studying one of the kiwi species, the brown kiwi, for the last 21 years and in this talk, Isabel will present some of their extraordinary findings.

Originally from Colombia, South America, Isabel has lived in New Zealand for the last 35 years and during 21 of those has been researching kiwi biology. Isabel is a wildlife biologist with broad interests including animal behaviour, parasite-host interactions, anatomy, morphology, sensory biology, and conservation. Her research is on island species, particularly birds, but also introduced mammals and charismatic land snails. Isabel has a passion for solving conservation problems, making new biological findings, and working with technology.

Our ability to effectively nourish an increasing global population is one of the key challenges facing humanity. Likewise, feeding New Zealanders well while balancing the environmental and economic aspects of our own food system remains difficult. And as individuals, how should we think about our own diets to make sure we are meeting our own needs, within budget, while still being able to feel good about what’s on our plates?

Food system challenges are global, local, and individual, and there are a range of voices telling us what we should do. What evidence do we need in order to act to achieve sustainable food systems and diets? What needs to be considered part of sustainability when it comes to food? This talk will focus on several aspects of the work of the Riddet Institute and the Sustainable Nutrition Initiative® that aim to inform the future of food systems and nutrition. At the foundation of this work is the idea that nutrition is integral to a sustainable food system: if we fail to produce and provide the food and nutrients to enable people to survive and thrive, we have failed, regardless of what else we achieve.

The talk will cover the nutritional adequacy of the global food system now and in the future; NZ food and nutrient production, trade, and availability; and the trade-offs between the different aspects of sustainability within diets.

Dr Nick Smith is a Senior Research Officer at the Riddet Institute, a New Zealand Centre of Research Excellence hosted by Massey University, where he works as part of the Sustainable Nutrition Initiative®, a program providing evidence for the sustainable food system debate and ensuring that human nutrition is seen as a key aspect of sustainability. Nick holds degrees in mathematics from Swansea University (UK) and in nutritional science from Massey University (NZ). His expertise is in mathematical modelling of complex systems, with a particular focus on human nutrition. His former research interest was in predictive models for dynamics in the human intestinal microbiome, and the influence on host health and wellbeing. He now studies the dynamics of global and national food systems and their impact on the nutrition of the global population.
