Join us for a lecture that will delve into the fascinating world of sharks. Having been on this planet for around 400 million years, sharks are a pin up of evolutionary success. They inhabit all the oceans of the world, from warm tropical mangroves to cold Arctic seas and include the world’s largest species of fish. In the natural world, their biological and ecological traits make them incredibly successful and their populations play a vital role in maintaining the balance of many marine ecosystems. However, in the face of ever increasing pressures, particularly from overfishing, their populations are under threat. Not all is lost though. Through targeted conservation efforts and seafood consumers making informed choices with their wallet, it is possible that the current global declines can be halted and reversed.

Dr Adrian Gutteridge’s relationship with sharks began when he was a self-professed “frothing little grommit”, terrified of sharks when surfing on the Sunshine Coast in Queensland, Australia. His terror turned to fascination, though, on a uni field trip on the Great Barrier Reef when he was snorkelling and a shark swam by. He was transfixed, absolutely forgot what he was meant to be doing and followed the shark until it swam off into the deep blue… and he’s not stopped since!

Adrian will join us by live video stream from Australia. For more information on Adrian and sharks, please see: https://www.msc.org/en-au/home/meet-the-wild-ones/shark-expert-dr-adrian-gutteridge

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

Posted on by

Rick Wentz: Geotechnical Engineer

Date: 5.30pm Thursday, 16 February 2023

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

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.

Thursday, 26 January, 2023: The Future of Regenerative Farming – practical experiences at Mangarara, Hawke’s Bay

Posted on by

Greg Hart, owner of Mangarara Farm and Eco Lodge

Date: 6PM, Thursday, 26 January, 2023

Venue: Lecture Theatre 1, EIT Taradale, Napier

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.

Deficit irrigation as a way to modulate Syrah quality parameters: Does less water make better wine?

Dr Chandré Honeth: Viticulture and Wine Science Lecturer

Date: 6:15pm, Tuesday, 6 December

Venue: A101, Eastern Institute of Technology, Taradale

Syrah is of specific economic interest to the Hawke‘s Bay wine industry. However, investigation into the production of Syrah has highlighted specific problems faced by producers in terms of ripening and quality. Imposing water stress during berry ripening has become a routine strategy for the modulation of grape berry composition and wine characteristics but responses of Syrah to deficit irrigation have been variable. Syrah is anisohydric in nature and therefore typically keeps its stomata open during soil drying, thus maintaining its growth and photosynthetic rate even in deteriorating conditions. This makes deficit irrigation management more challenging as a fine line exists between moderate stress which elicits positive fruit attributes and severe stress which leads to defoliation and a reduction in photosynthesis.

To have a better understanding of how Syrah vines respond to soil drying, and how best to schedule irrigation for optimising quality would benefit all growers in the Hawke’s Bay region in terms of both conserving increasingly scarce water resources and improving fruit quality for winemaking. Two Syrah vineyards, one in the Gimblett Gravels and one in the Bridge Pa Triangle sub-region were selected and monitored during the 2020 and 2021 season.

Dr Honeth will talk about the results from this trial and also give further insights into using deficit irrigation as a tool for improving quality parameters in Syrah in Hawkes Bay. She received her PhD from the University of Stellenbosch (South Africa) where she investigated the influence of UVB radiation on berry metabolites in Sauvignon Blanc grapes, and she is currently a lecturer and researcher in Viticulture at the New Zealand Institute of Skills and Technology.

Tuesday, 25 October: From Mihoutao to Kiwifruit

Posted on by

Ross Ferguson: Honorary Fellow, Plant & Food Research, Auckland

Date: 6pm, Tuesday, 25 October 2022

Venue: Lecture Theatre 1, Eastern Institute of Technology, Taradale

Admission: Gold coin donation

Kiwifruit have been a cultivated crop for less than a century in New Zealand and have successfully become a well known fruit by consumers all over the world.

Kiwifruit originally come from China, where they are known as Mihoutao. The kiwifruit of commerce are large fruited selections of Actinidia chinensis var. chinensis (yellow and red fruit flesh) and A. chinensis var. deliciosa (green fruit flesh). The two varieties of A. chinensis differ in the place and timing of their initial domestication. Their domestication resulted from multiple selections from wild germplasm in the case of A. chinensis var. chinensis and from a single introduction of wild germplasm of A. chinensis var. deliciosa to New Zealand.

Ross Ferguson will tell you how, from an introduced plant, kiwifruit became an important commercial New Zealand fruit crop.

Ross Ferguson has been at the Mt Albert Research Centre, Auckland for more than 50 years, working on kiwifruit breeding and improvement. A new male kiwifruit cultivar , ‘Ferguson’, has been named for him and was released in 2019.

He was appointed Officer of the New Zealand Order of Merit for services to the New Zealand kiwifruit industry in 2007. Ross has published more than 40 reviews on various aspects of kiwifruit biology.

Thursday, 8 September: Towards carbon neutral fruit production

Posted on by

Jim Walker: Principal Scientist at Plant & Food Research

Date: 6pm, Thursday, 8 September 2022

Venue: Lecture Theatre 1, Eastern Institute of Technology, Taradale

Admission: Gold coin donation

As global leaders in sustainable production systems, the New Zealand fruit sector must continue to innovate to reduce both agrichemical inputs and CO2 emissions. Regulatory, consumer and environmental concerns over pesticide use are continual challenges for both the agrichemical industry and our apple sector. The pipeline for pesticide development has become more complex, reducing the frequency of new active ingredient availability. Adding to this challenge is the on-going loss of existing agrichemicals and increasingly trade-restrictive phytosanitary measures. Now export markets have signalled the need for our fruit sector to reduce their CO2 emissions with the challenge of becoming carbon neutral by 2050.

Is this achievable or an unrealistic pipedream? Issues and options for the future of New Zealand’s export fruit production will be presented in this lecture.

Dr Jim Walker is a scientist with Plant and Food Research (Hawke’s Bay) who is well known for his role in the development and implementation of the Integrated Fruit Production programme, an approach to pest management that has become a cornerstone of New Zealand’s apple export programme. He has led a team that has helped apple growers adopt practices that has greatly decreased pesticide use and residues. This programme prioritised greater use of biological control and non-chemical methods and has contributed to a 90% reduction in the quantity of insecticide used in New Zealand apple production today.

The research interests of David Prior include understanding the material processes that control the behaviour of crystalline materials (including rocks, industrial ceramics, metals, and ice), as well as the large-scale tectonic and thermo-chemical processes that control the evolution of the Earth’s interior.

Thursday 11 August: The state and health of Hawke’s Bay’s environment – Hawke’s Bay Regional Council

Posted on by

Environmental Science team: Hawke’s Bay Regional Council

Date: Thursday 11 August, 6pm-7pm

Venue: Hawke’s Bay Regional Council Chamber (159 Dalton Street Napier)

Our environment is our precious taonga. It underpins all the values that we hold for our health, our wellbeing, and our physical and spiritual needs. To ensure that these resources stay healthy for years to come, we need to understand the current health of land, rivers, lakes, and beaches – and how climate change and human use will affect them in the future.

Source from: HBRC

The science of our natural resources underpins how people manage them moving forward, in a way that ensures that the resources are still healthy and functioning for generations to come.

The Hawke’s Bay Regional Council (HBRC) has a team of technical and analytical specialists who collect environmental information. Over twenty scientists from the environmental science team of the HBRC have used this information to gain important insights into the health of the natural environment and the processes driving changes in these systems in Hawke’s Bay.

This presentation will introduce the findings from three-yearly check-in environment reports about the condition of waters, land, air, and coast that support the unique and valuable biodiversity in the Hawke’s Bay region. In addition, this talk will highlight where things are going well and where things may need more support.
