Thursday, 3 February: The Future of Regenerative Farming – practical experiences at Mangarara, Hawke’s Bay

Greg Hart, owner of Mangarara Farm and Eco Lodge

Date: 6.00pm Thursday, 3 February 2022

Venue: Lecture Theatre 1, EIT Taradale, Napier

Admission: Gold coin donation

Regenerative Agriculture (RA) is an ecological model that aims to correct perceived failings in our current systems of agriculture. The RA movement acknowledges that farmers can mitigate or reverse the negative impacts of the way that animals and plants are currently raised and grown for food production but suggests that they can benefit themselves at the same time. RA is touted as a part of the solution to reverse climate change, biodiversity loss and declining water quality, whilst improving the wellbeing of rural and farming communities and the quality of the food produced.

However, there is a lack of clarity about what RA actually is, scepticism about its claimed benefits, and uncertainty whether or not it is relevant to New Zealand farmers and agricultural production.

In this lecture, Greg Hart will talk about his practical experience of applying regenerative agriculture at Mangarara, how to provide a stable financial platform for the continued restoration of the ecosystem, and innovating regenerative farming practices.

Greg Hart has made the switch from a traditional sheep station with typically 3,000 ewes to a diverse stock of approximately 1000 ewes, 500-1,500 lambs, 20-40 dairy cows, 60-100 Berkshire pigs, 150 Angus heifers and 100-200 other cattle. Meat is sold both locally and in Auckland. Over 100,000 trees have been planted and the quality of the soil is actively monitored and managed.

At the end of this lecture, you will have an idea about how a diverse and integrated farm can maintain the balance between ecosystem restoration and the production of healthy, nutritious food.

Wednesday, 16 February: 1931 Earthquake Commemorative Lecture: Liquefaction – What is it, why it matters and what we can do about it

Rick Wentz: Geotechnical Engineer

Date: 5.30pm Wednesday, 16 February 2022

Venue: The National Aquarium of New Zealand – 546 Marine Parade, Napier

This lecture has been advertised as part of Napier’s Art Deco Festival and is therefore likely to be popular. Our venue, the Aquarium, has applied a capacity limit of 50 attendees under red traffic light. Please come early to ensure a seat.

Admission: Gold coin donation

This is the commemorative lecture for 1931 Hawke’s Bay Earthquake, also known as the Napier earthquake, which occurred at 10:47am on 3 February 1931, killing 256, injuring thousands and devastating the Hawke’s Bay region.

This year Rick Wentz is invited to give a lecture on liquefaction. The focus of this lecture will be to define liquefaction, describe the cause and the conditions under which it typically occurs, and to highlight its potential impacts on the built environment. Also discussed will be some things that individuals and communities can consider doing to reduce the impacts of liquefaction on homes and infrastructure.

Mr Wentz grew up in Northern California and completed his MS in Civil Engineering at the University of California – Berkeley where he got to experience the 1989 magnitude 6.9 Loma Prieta earthquake first hand. He has been a practising geotechnical engineer for 30 years and has worked on a range of projects from residential subdivisions to nuclear power plants in the U.S., South America and New Zealand. He spent several years working in the corporate world before starting his own consultancy in Northern California in 2005. His career focus has been geotechnical earthquake engineering including design, forensic investigation of post-event ground and foundation performance, project / peer review, and applied research. Mr. Wentz came to New Zealand “for 1 year” in 2011 to work in the Christchurch Rebuild and recently celebrated his 10th anniversary of living and working here. Notable NZ projects include serving as an expert on the Government-appointed panel that investigated the performance of the Wellington Statistics House during the 2016 Kaikoura earthquake, and helping to develop the MBIE document Planning and engineering guidance for potentially liquefaction-prone land. When not pondering liquefaction and other geotechnical issues, Mr Wentz enjoys flyfishing, cycling and tramping with the family.

Sunday, 27 February: 2022 Beatrice Hill Tinsley Lecture (RASNZ) A deadly dance: When black holes and neutron stars collide

Dr Heloise Stevence: Research Fellow of the University of Auckland

Date: 2.00pm Sunday, 27 February 2022

Venue: Lecture Theatre 1, EIT Taradale, Napier

What happens when the densest objects in the universe collide at half the speed of light? It starts with a stretch of a wobble in the fabric of spacetime, and sometime sends in cosmic explosions that create some of the rarest and shiniest elements in the Universe. Together we’ll learn how some of the most massive stars in the cosmos live and die with bang, to create the black hole and neutron star mergers we can “hear” colliding a hundred million light years away. This 45 minute “lecture” will combine cutting edge science and wacky humour to make the mysteries of merging black holes and neutron stars accessible to all ages and backgrounds.

Dr Heloise Stevence is an energetic, enthusiastic, educational and entertaining speaker well able to reach out to audiences of all ages and levels. Heloise, born and raised in France, moved to the UK to study Physics and Astronomy at the University of Sheffield. After working as a support astronomer at the Isaac Newton Group in La Palma for a year, she obtained her Masters of Physics in 2015 and subsequently started a PhD studying the 3D shape of Core Collapse Supernovae. She completed her PhD in 2019 and joined the University of Auckland as a Research Fellow to research the evolution of massive stars to better understand how they die and produce Supernovae and Kilonovae.
