title: Science-practice roadshow 1: Summary perspectives from centralised entities and agencies

authors: Serrao-Neumann, Silvia

abstract: Flooding is Aotearoa-New Zealand’s most frequent natural hazard, regularly damaging buildings and infrastructure networks, and causing months of disruption to communities and businesses (Hutchings et al. 2019). Also, floods have indirect, cascading, and more intangible impacts (Lawrence, Blackett, and Cradock-Henry 2020), such as the withdrawal of future investment or the emotional stress of recovery. flood risk is predicted to rise quickly due to the combination of climate change and rapid urban intensification (Ministry for the Environment and The Flood Risk Management and River Control Review Steering Group 2008). 

Currently, there is no consistent approach to accurately determine flood risk on a national scale, nor how this may be changing as the climate warms. Instead, flooding risk assessments are done for individual catchments or locations, with the goal of managing and mitigating on the local scale. Local and regional governments vary widely in their capability and capacity to undertake this work (Ford, Berrang-Ford, and Berrang Ford 2011) and, thus, significant differences in data availability and modelling approaches mean that integration of results to gain a pan-region or nationwide picture has not been possible. 

The ‘Mā te haumaru ō nga puna wai ō Rākaihautū ka ora mo ake tonu: Increasing flood resilience across Aotearoa’ research develop a detailed nationwide model that could inform strategic and co-ordinated nationwide decision-making and regulations to support improved resilience to flood risk across the country. Utilising new methods and advances in computer processing and automation, the programme is developing a dynamic risk modelling framework that will assess flood hazard for every catchment in the country and under differing climate scenarios. The model will account for the risks to both built infrastructure and communities so that a fuller understanding of societal costs and impacts can be established. The model’s utility for supporting decision-making will be investigated using an initial set of scenarios for environmental planning, policy settings and infrastructure investment options. Two overarching themes across all of the research - Mtauranga Mori and Uncertainty – are designed to utilise the diverse knowledge systems available to develop tools that are relevant for communities throughout Aotearoa-New Zealand, and to take into account and communicate more clearly flood risks. 

Improved resilience to flooding across Aotearoa-New Zealand is a key outcome sought by the research programme, however it cannot be achieved by research alone. Instead, knowledge and information developed within the programme must be utilised by practitioners in their work to assist communities to plan for, manage, mitigate and avoid flood risks. New knowledge from the programme must be incorporated by practitioners into further tools, policy and decision-making frameworks. This knowledge translation however is not a straight forward process (Dilling and Lemos 2011). Cultural, behavioural and cognitive differences between those who produce and those who utilise knowledge mean that research outputs may not fit the requirements of their intended users, and thus, uptake of research outputs may be compromised. Conversely, strong engagement of knowledge users in the knowledge production process is known to increase the likelihood, and impact, of knowledge implementation. 

Stakeholders are key members of the programme’s research team, representing views across central and local government, engineering, planning consultancies, emergency management, insurance and banking industries, and Te Rūnanga o Wairewa (Banks Peninsula). To broaden the range of stakeholder perspectives, and to facilitate relationships across the programme, we have established a boundary organisation – Te W Te W . Boundary organisations (Guston 2001; Kirchhoff, Esselman, and Brown 2015) are forums that bridge between the two relatively different social worlds of knowledge producers (researchers/scientists) and users (practitioners/policy makers). These forums create and sustain legitimate space and collaboration for knowledge/information to be co-designed, co-produced and co-disseminated (Serrao-Neumann, Di Giulio, and Low Choy 2020). Within our programme, Te W Te W is responsible for organising and facilitating communication and collaboration activities – events (Science-Practice oadshows), communications channels such as an electronic newsletter and website, and learning opportunities. Through this organisation, we are fostering trust, legitimacy and capacity for information use so that our research results will be usable, useful, and used. 

This report summarises the discussion and perspectives shared at the first Science-Practice Roadshow held in October 2021.

title: Eke panuku, eke tangaroa! How Black Ferns 7s athletes navigate Instagram and inspire the next generation in Aotearoa

authors: Keet, Thandiwe Maia

subjects: Gender

abstract: This thesis considers the role of Instagram in the lives of players on the New Zealand Black Ferns 7s rugby team, and audience engagement with players’ social media accounts. Using a mana wāhine methodology, this study explores how Black Ferns 7s players utilize and navigate Instagram, through mixed-methods enquiry, including a social media analysis of 8 players’ accounts, interviews with 3 Black Ferns 7s players, and talanoa sessions with members of the women’s rugby community in the Bay of Plenty, supplemented by input from Black Ferns players and fans via direct messages on Instagram. The quantitative social media analysis identified 4 key themes in players’ Instagram posts: achievement, team & rugby, life outside rugby, and culture & vulnerability. The analysis reveals that players post the most regarding their “team & rugby”, generating an “athlete first” self- representation. It finds a statistically significant difference in the thematic content of Instagram posts based on squad seniority and the number of followers a player has. Followers were found to engage most with posts regarding “achievement”, and the least with posts regarding “culture and vulnerability”.
The interviews elaborate upon these quantitative differences by highlighting why athletes specifically use Instagram, insights into Black Ferns aspirational team dynamics, and the importance of a player’s life outside of rugby. The thematic analysis also reveals the digital economic and collective labour involved in producing social media content as a member of this team, and what it means to be culturally “authentic” online in Aotearoa. It reveals the unique elements generated by the team-sport context of this study, including intra-team differences in social media usage. Furthermore, hauora, Indigenous role modeling, and Tall Poppy Syndrome emerge as factors particularly unique to the cultural context within which this study takes place. The discussions culminate in the establishment of a layered understanding of the external, internal, and individual factors which shape Instagram posting habits, and the features which most significantly impact why audiences follow the curated displays Black Ferns 7s athletes provide online.
This project contributes to international literature on sportswomen’s use of social media, demonstrating the powerful ways that players support one another in what, when, and how they post, and the importance of cultural identity in Māori and Pasifika players’ social media engagement. It further reveals the importance of team culture in shaping individual players’ social media and audience engagement. This thesis also highlights the significance of sporting and cultural histories and intersectional identities in digital self-representation and fan engagement with sportswomen’s social media usage.

title: The viability of commercially relevant New Zealand seaweeds as a novel source of protein: The impact of processing on the extraction efficiency of protein

authors: Battershill, Zoe

subjects: Seaweed

abstract: The world’s population is increasing and with it so too is the demand for food production specifically protein which is essential for human nutrition. However, relying solely on animal-based proteins is increasingly problematic given growing global environmental impacts. Thus, novel protein sources are increasingly investigated, particularly plant-based alternatives due to their smaller carbon footprint. Seaweeds hold potential as a novel protein source due to their relatively high protein content and quality as evidenced by essential amino acid content. However, seaweeds’ cell structure, with unique polysaccharides, complicate protein availability in terms of human digestion, necessitating procedures to disrupt the cell if seaweeds are to be a reliable protein source.
This research thesis sought to investigate which of six New Zealand seaweeds (five different species) had the highest raw potential as a protein source, and if this protein’s extraction could be improved by food grade standard, industry relevant processing techniques. 
Seaweeds assessed included: Pyropia plicata wild harvested from the Tauranga, Bay of Plenty (North Island) and Kaikōura, Canterbury (South Island); Macrocystis pyrifera and Undaria pinnatifida provided by commercial supplier (NZ Kelp); and Ulva sp. B and Ulva ralfsii harvested from land-based cultivation at Coastal Marine Field Station (CMFS), University of Waikato, Tauranga. All six were analysed for proximate composition (C, H, N, S, and ash), content of protein (as amino acids), total lipids, carbohydrates, fibre, minerals, and heavy metals. Antioxidant capacity was evaluated as new research shows this can influence protein bioavailability. From these results Ulva sp. B and Ulva ralfsii were chosen as the potential protein sources with their protein content 151 mg/ g and 138 mg/ g, respectively.

The effects of two alternative processing methods, which were applicable to industry for human nutrition, were then applied to these two species to assess their impact on the extractability of protein. The two chosen processing treatments were enzyme hydrolysis using a commercial mixture of enzymes (Viscozyme®) to target the chemical degradation of cell wall polysaccharides, and homogenisation to target the mechanical degradation of the cell wall structure. These were used alone and combined in a factorial experimental design and found that the combination of both processing methods yielded the greatest extraction efficiency 55.2% and 63.7% extraction efficiency for U. sp. B and U. ralfsii, respectively.
While this study was limited in scope, it demonstrated the potential for cultivated seaweeds in New Zealand to be successfully processed to enhance their available protein and serve as a novel protein source for human nutrition.
